Description

Nuclear waste packaging modules
Introduction of the present invention is used to encapsulate the composite can of the nuke rubbish of various different radiation levels, and they can the safe and permanent buried waste disposal place that is put in.
The means of various encapsulation nuke rubbish have in the prior art.A kind of packaging body that uses the earliest is 55 gallons a steel drum.This steel drum uses " playing roll-type " waste material in early days to bury in the place system.After encapsulation, the surface emissivity of this steel drum is often too high, so that does not allow to load and unload them by the staff; Therefore, the long-armed cranage of the steel drum after the encapsulation.These cranes hang in an easy native trench to steel drum, bury there and put steel drum.Unfortunately, using the 55 gallons of steel drums of this class in this trench, is a kind of extremely not satisfied method of nuke rubbish underground disposal.Fill out loosening the soil of these trenches not and come, be more prone to seep water manyly compared with the closely knit representative closely knit rock stratum at the bottom of loading soil or forming trench that forms the trench side.Therefore, the Tu Hao with infiltration that centers on the pine relatively of steel drum makes these trenches assemble a large amount of stationary waters, and this is called as " bathtub effect ".Corrosion and breaking-up take place in the wall that these stationary waters finally cause being embedded in the steel drum in the trench.The compacting in time of the breaking-up of steel drum and soil turns over and causes moving downward or sinking of soil, and this makes and forms depression at the top of trench.This depression is assembled surface water, further worsens thereby trench is assembled on steel drum and kept a tendency of cheating stationary water.The increase of the stationary water that causes is sunk soil further, and quickens to bury the corrosion and the breaking-up of the steel drum that is placed on the there.The corrosion of the steel drum container in this type of place and breaking-up cause phreatic certain radioactive contamination there of flowing through.
In order to solve and this type of encapsulation disposal system relevant problem of " playing roll-type ", studied the packaging body of wall with quite thick radiation-screening and water-impervious.Opposite with the thin-walled of 55 gallons of steel drums, the heavy wall of these concrete packaging bodies does not reduce to the packaging body surface emissivity that forms must use long-armed cranage, and can be loaded and unloaded by operating personnel safely on the contrary.In addition, the ability of thick concrete layer opposing groundwater erosion is much bigger.In use, these heavy wall concrete packaging bodies are transported to the place that waste material produces, and this class place is representational to be nuclear power station.Waste material is directly thrown away the inside into these packaging bodies, and packaging body is sealed on the spot.Then the packaging body of sealing is transported to remote disposal site and buried and put.The relevant surface emissivity of these concrete packaging bodies is very low, therefore can stack with fork truck order in burying the trench of putting of shielding.
Although the encapsulation of this kind concrete is better than the steel drum type encapsulation that " playing roll-type " system uses, this specific packing forms still has many shortcomings.At first, these specific packaging bodies can not load and unload the waste material of high radiation level easily, as useless control rod; The concrete wall thickness of packaging body is enough to the surface emissivity of packaging body is attenuated to the acceptable level seldom or never.Secondly, relevant problem is the concrete packaging body surface emissivity changes with the radioactivity that is packaged in specific waste material wherein.Because people always wish to put in the trench below the packaging body that will " the hottest " packaging body be enclosed in the radioactivity minimum burying, so the fact that the surface emissivity of these special package bodies changes in broad range makes to be difficult to determine the optimal sequence stacked.The 3rd, these packaging bodies in fact only have the unique radiation together and the restraining barrier of water between contained waste material and outside soil layer.If the concrete wall of these packaging bodies, has not just had the water of reserve or radiation blocking layer owing to seismic disturbance breaks.The 4th, these concrete packaging bodies are put the place and are reclaimed very inconvenient from burying.If seismic disturbance breaks to the degree that may spill radiomaterial a specific packaging body, last shortcoming is the defective of an especially severe so.
Obviously, need a kind of nuke rubbish packaging body of underground disposal, it can encapsulate the radioactive waste of different radioactivity levels, and these waste materials are demonstrated identical or similar at least surface emissivity level.Ideal situation is, just in case for a certain reason and the outer wall of packaging body breaks, a kind of like this packaging body should have multiple water and radiation blocking layer to surround contained waste material.At last, this packaging body should stack the configuration of the damage that the incident that can highly withstand an earthquake or other natural disturbance cause, and just in case a certain special package body of stacking is damaged, should be easy to reclaim.
Therefore, the invention belongs to a kind of energy and will be contained in the composite can that the interior radioactive waste of pig is packaged into the rock-steady structure shape that can bear pressure load.This composite can comprises a hard outer layer container that surrounds waste material fully, the restraining barrier of the first road radiation and water is provided for waste material, an internal layer container that forms by pig, for waste material provides the second road radiation blocking layer, and the fluid substance layer that can harden in the middle of being positioned at, it has filled up the space between outer layer container and the internal layer container, for waste material provides another road radiation blocking layer, and for composite can provides a quite hard enhancing inner casing, it has strengthened the compressive strength of composite can.
The present invention comprises that also the radioactive waste that a kind of energy will be contained in the pig is packaged into the composite can that can bury the rock-steady structure shape of putting.This composite can comprises the hard outer layer container of a rectangular prism shape that is made of binding material, the restraining barrier of the first road radiation and water is provided for waste material, an internal layer container that forms by pig, the restraining barrier of the second road radiation and water is provided for waste material, and the grout blanket in the middle of being positioned at, it has filled up the space between outer layer container and the internal layer container fully, for waste material provides the restraining barrier of radiation of another road and water, and for composite can provide one can the support pressure load quite hard enhancing inner casing.
Secondly, according to of the present invention be a kind of dense package array of nuclear waste disposal composite can, in array is imbedded soil after, it meets consistent with the variation of native shape neatly.Said herein array comprises many composite cans, corner cube prism of the outer appearance of each composite can, sidewall and two end walls that size shape equates of having many size shape to equate.Said herein composite can end face phase ground connection is stacked the pillar that becomes to adjoin each other, and the sidewall of all composite cans all is coplanar in the particular post herein, so each composite can pillar can be with respect to the pillar vertical moving of adjacency.
Once more, but according to of the present invention be but that a kind of nuke rubbish with compacting is encapsulated in the flow process in the pig of compacting, this flow process comprises compacting container and waste material wherein; Container after at least one compacting is placed on the middle body of composite can container, and fills up the annulus that is compacted between container and the composite can container with a kind of fluid substance that can harden.
The container of composite can be put into the pig of many radioactive wastes.Can each pig of compacting, to increase the pig number of the composite can container of can packing into as far as possible.This compacting also makes less suction of waste material and infiltration owing to the waste material that hardened has increased overall compressive strength.Therefore in optimum implementation of the present invention, pig bears a compaction force that makes pig and contained object both thereof that inelastic deformation take place, and has eliminated " rebounding " of pig after the compacting and contained object thereof.This " rebounding " can form crack or space originally in composite can, rebound if produce this kind when grouting still is in mecystasis.
The pig of compacting can be placed on the central authorities of the hard outer layer container of composite can, so that the composite can surface emissivity that forms equates.In addition, the number of the pig that is in the milk in hard outer layer container can select to such an extent that make the composite can surface emissivity of formation be no more than a preset value.The loading and unloading of composite can for convenience, the bottom of composite can outer layer container can comprise parallel substantially groove line, inserting the shovel fork of fork truck, and the top of this container can comprise and manyly can detachably be connected to the I shape bolt anchor ring that the hoister hook gets on.In addition, hard outer layer container can comprise a tabular lid, it has a lid fastenings at least, and this part can insert when the mortar that pours into is in unhardened state in the mortar, and this part just is used for lid is anchored on the outer layer container after the mortar sclerosis.
At last, the shape of the hard outer layer container of composite can is corner cube prism preferably, and the sidewall that has many size shape to equate is so that composite can be stacked the pillar that becomes to adjoin each other densely.In optimum implementation, composite can is hexagonal prism.The closely packed array that does not produce sinking that this sexangle prism forms, have the trench overlayer of fully big compressive strength, but can meet consistent neatly with the variation of the trench shape that causes owing to seismic disturbance or other corollary failure with supporting soil property type.

With reference now to Fig. 1,, identical Ref. No. is represented identical parts among all each figure among the figure, the packaging facility 1 of system of the present invention comprises four stifled divider wall 2a, 2b, 2c and 2d, they surround a remote control loading and unloading waste material encapsulation region 3 that is positioned at the buildings left side, one is positioned at the composite can loading of buildings central authorities and the contact loading and unloading garbage area 85 that 60, one of traffic zones are positioned at buildings the right.Remote control loading and unloading are loaded and unloaded garbage area 3 and 85 and are comprised a driving main line 7 and 87 respectively with contact.On these two driving main lines 7 and 87, truck 13 and 95 transports to be contained in the remote control loading and unloading in the quite light pig of weight (being lining, 55 gallons of steel drums and LSA container) and contact and loads and unloads nuke rubbish, produce the place and ship from being positioned at a distance waste material, go so that be encapsulated in the composite can 200 of quite heavy closely knit filling.In optimum implementation, the final disposal place 150 by the composite can 200 of packaging facility 1 filling is positioned at the place near facility 1, to shorten the distance that filling back composite can (it may weigh more than 30,000 pounds) must transportation as far as possible.The facility that is surrounded by divider wall should be noted that at the very start away from waste material produces the place near final disposal place 150 has three main relevant benefits at least.The first, do not need that quite heavy composite can 200 is transported to waste material and produce the place.The second, eliminate waste material generation place and encapsulated the contingent contamination of heavy.The 3rd, divider wall 2a, 2b, 2c and 2d are encapsulated the contingent contamination of heavy to disposal site 150 and are reduced to minimum.
Turning rate is described the remote control loading and unloading garbage area 3 of facility 1 more particularly now.This garbage area 3 comprises a track 9, and there is inlet (not shown) and one outlet 11 in track 9, is used for accepting to transport truck 13.This kind truck 13 is contained in nuke rubbish a kind of can reusable shielding the shipment in the jar 15 usually, and the type of shipment jar 15 obtains Department of Transportation or United States Nuclear Regulatory Commission's approval.The inside of this kind shielding shipment jar 15 has been equipped with the metal or the plastic bushing (not shown) that in fact hold waste material.The garbage area 3 of facility 1 comprises that further the same 18, one high of the processing platforms of the vehicle body of a height and truck 13 have the radome 19 of hook gear 21, and the mobile type hoist 23 of a remote control.Radome 19 is preferably made by the box hat of band leadwork, and leadwork thickness will be enough to the radiant quantity that untouchable waste material produces is reduced to the acceptable level.Crane 23 comprises a main electromotor 25, and it forms dismountable the connection by an electronic pulley blocks device 27 with the hook gear 21 of radome 19.Mobile type hoist 23 further comprises a balladeur train 29 that main electromotor 25 is moved along " X-axis " direction (track 9 that is parallel to the main line 7 of driving a vehicle), and one makes main electromotor 25 along the mobile overhead traveling crane 33 of " Y-axis " direction (forward position that is parallel to facility 1).Vertical adjustable electronic pulley blocks device 27, combine with balladeur train 29 and overhead traveling crane 23, mobile type hoist 23 is swung to radome 19 above the shipment jar 15 that transports truck 13, from container 15, hang out the dress waste material lining, and with lining be placed on processing platform 18 want on the position.Though in optimum implementation, used remote control mobile type hoist 23, can use the existing remote operation hoist equipment of any other type to come the supplementary copy invention by the TV monitor operation.Outside main electromotor 25, between mobile type hoist 23 and radome 19, also connected a secondary hoister 35.Hawser and suspension hook (not shown) in the secondary hoister 35 control radomes 19, the position of waste material lining in shielding shipment jar 15 makes it possible to detachably get one's things ready approximately.
The remote control garbage area 3 of buildings 1 also comprises a Characteristics Detection station 37, and it has various radiation detector 39 and ultrasonic detector 41, meets the shipment inventory with the contained object that verifies lining in the shipment jar 15.Radiation detector 39 is used for measuring contains the radiation intensity that waste material produces in the lining, and checks the title of the radiant-energy spectrum of this waste material whether to meet the degree of accuracy scope of loading and transporting inventory.Ultrasonic detector 41 is used for measuring whether have radioactive liquid in the lining.The Federal Government regulation, strictness forbids burying the radioactive waste of tapping shape, and therefore, the information that is provided by ultrasonic detector 41 is most important.Radiation detector 39 and ultrasonic detector 41 boths utilize the cable in the groove 43 that is placed on processing platform 18 to be electrically connected with the storage unit of reading dial 45.Though do not express any one numeral especially, but a central computer is preferentially imported in the output of radiation detector 39 and ultrasonic detector 41, so that note, and determine that this particular combinations jar can load the waste material of many a spot of a certain particular types before the surface emissivity of composite can 200 surpasses a preliminary election limit.Central computer can further calculate and must pour into how many mortar could seal waste material suitably in a specific loading composite can, and when the aqueous waste material that contains in the waste material that holds in the ultrasonic detector 41 indication linings reaches the number percent that can not allow, can start warning circuit.
In optimum implementation, the height of processing platform 18 selects to such an extent that meet the height of tandem truck 13 vehicle bodies approx, therefore when shipment jar 15 is removed lid, and the radiation that the operating personnel on the platform 18 are shot out by tank deck can not.In operation, radome 19 drops in the shipment jar of opening 15, connect to live a jar interior lining, then swing also is reduced to rapidly from several inches of these sensors on the sensor 39 and 41 at Characteristics Detection station 37, so that shadow zone 3 be subjected to by penetrating and, reduce to minimum in radome 19 bottoms by platform 18 radiation reflected.In optimum implementation, processing platform 18 is made of solid concrete slab, both in order to make facility 1 structurally become as a whole, also in order to shield.Explained below after the 26S Proteasome Structure and Function of depositing well 50 of adding a cover that the purpose of a back shielding is just clear.Though the Characteristics Detection station 37 of optimum implementation has included only radiation detector 39 and ultrasonic detector 41, if desired, also can comprise the detecting device (the RTV remote television watch-dog of for example visual discriminating waste material) of other type.
At last, the remote control of facility 1 loading and unloading garbage area 3 comprise four add a cover deposit well 50, also comprise between a repair operation that forms by barrier shield 54 and enter by shield door 55 53.The well 50 of depositing that each is added a cover comprises a well that is generally drum shape that binds with the plate-like lid.That adds a cover deposits the storage area that well 50 provides a safe ready, is used for depositing by Characteristics Detection station 37 and checks out the nuke rubbish that has excess liq or other unacceptable condition.In addition, when grouting station 118 was blocked, that adds a cover deposited well and can be used for temporarily depositing the waste material of remote control loading and unloading.Cover the material of the pan-shaped cover of depositing well 50 and thickness to select can make the waste material of the remote control loading and unloading that are stored in the well be incident upon the perform region of shadow zone 3 radiant quantity be reduced to below the security level.The repair operation district provides the isolated area in the remote control loading place 3 of a facility 1, and the lining that breaks the there lining of liquid (or contain) can suitably be repaired or handle, and does not pollute the major part of remote control loading place 3 or the most danger of facility 1.As becoming later on more obviously, the broken wall that provides an independent room 53 to repair lining is important, because when lining is in the milk in composite can, lining provides one of restraining barrier of composite can 200 interior three radiation and water.When finding free fluid in the waste material lining, 53 provide a zone between repair operation, liquid can mix mutually with suitable absorbing agent or other setting medium there, is suitable for burying the solid shape of putting so that liquid become in existing Federal Government regulation regulations.Under normal circumstances, neither can use depositing well 50 and also can not using between repair operation 53 to handle remote control loading and unloading waste material of adding a cover.On the contrary, after finishing Characteristics Detection, these waste materials are promoted by remote control usually and pass through by barrier shield 57a that forms 3 back sides, shadow zone and the formed tortuous outlet 56 of 57b, and put into the composite can 200 on the railcar 64, and railcar sails for grouting station 118.
Composite can loading and traffic zone 60 are positioned at the central authorities of facility 1, between remote control loading place 3 and contact loading place 85.Composite can loads and this middle position of traffic zone 60, make it can be easily for the remote control loading place 3 of facility 1 with contact loading place 85 and serve.Usually, the traffic zone 60 that composite can loads comprises the whole parts and the function of its mobile type hoist 23 of describing before comprising of mobile type hoist 62(of a routine), be deposited in the composite can on the external orbital car 64 of buildings 1 with loading.These railcars can be freely move along the load rail device 66a and the 66b of pair of parallel.For railcar 64 can be moved freely, base 70a and the 70b of attachment rail 68a and 68b tilt a little, so that make the track 68a that is limited to load rail device 66a and 66b and the railcar 64 on 68b gravitate and roll down track freely.Though all do not illustrate among several figure, each load rail device 66a and 66b comprise many pneumatic shut-down mechanisms, so as along each different loading of load rail device 66a and 66b, be in the milk and the position of adding a cover on railcar 64 is stopped.Composite can loads and traffic zone 60 comprises a rail set that returns 74, and the vergence direction of its base 78 is opposite with the vergence direction of the base 70a of load rail device 66a and 66b and 70b.The reverse direction of the base 78 of return trajectory device 74 tilts, and makes after the grouting and the composite can 200 of adding a cover of railcar on remove, and can get back to composite can loading and traffic zone 60 freely rolling on track 76 under the effect of gravity.At last, its preferably thick at least 12 inches solid concrete wall of barrier shield 79() places between rail set 66a and the return trajectory device 74, when being loaded into a composite can and accepting grouting with convenient remote control loading and unloading waste material, shielding contact garbage area 85, the irradiation that waste material is loaded and unloaded in the remote control that makes it not contained by radome 19.This barrier shield 79 generally serves a dual purpose, loading and unloading garbage area 3 is trapped among in the same facility as the remote control to make on the one hand contact loading and unloading garbage area 85, the remote control loading place 3 that can make facility 1 on the other hand with contact loading place 85 and can use a composite can loading and traffic zone 60 jointly.A loading and the transportation system that benefit has removed from providing dual in back.
Forward contact loading and unloading garbage area 85 now to, this district of facility 1 comprises many general parts that have in remote control loading place 3.For example, loading place 85 comprises a driving main line 87, this main line 87 comprise with the driving main line of discussing in the past 7 in track 89, inlet 90 and the outlet (not shown) of same type.Loading place 85 also comprises a processing platform 93 that preferably is made of solid concrete slab, and it is identical with the truck body height highly approx, unloads from transporting truck 95 with the convenient waste material that encapsulates.Loading place 85 also comprises two Characteristics Detection station 107a and 107b, also comprise add a cover deposit well 113.At last, loading place 85 comprises between a repair operation 112, the container that breaks with repairing, and encapsulate inappropriate waste material with other and change into and can accept to bury the solid shape of putting liquid.
But except these and loading place 3 common means, loading place 85 has also comprised other parts of some unique existence in buildings 1.For example, used a quite light turning crane 99 of load with magnetic or Vacuum hoister 101 to replace the quite heavy mobile type hoist 23 of loading place 3.Because the waste material radiation level that handle loading place 85 is quite low, can directly contact, so do not need the crane that can mention heavy radome 19 that in loading place 3, uses with the staff.Therefore, as long as the crane that uses in the loading place 85 can be mentioned the nuke rubbish of slight encapsulation, these waste materials generally are contained in when arriving buildingss 1 in 55 gallons the steel drum 97.But though can use some slight shielding on the contact region 85 of buildings 1, it is very low usually to distinguish its radiation level of waste material of handling, thereby each holds the steel drum 97 of waste material not need the shielding of degree of depth ground.Therefore, preferably constitute a conveyor system 103 by roller bearing, it will make the loading and unloading of the steel drum 97 that holds waste material become greatly convenient.At last, provide a powerful compacting machine 110, it not only is compacted into smaller volume to waste material, and steel drum on every side is expressed to the elastic limit that surmounts steel, makes that the volume of waste material can not " rebound " in filling process.This is an important advantage, and it will describe in detail in the back of this paper.
Conveyor system 103 had both comprised compacting machine travelling belt 105a and the 105b that pair of series is arranged, and also comprised a repair operation travelling belt 106.Compacting machine travelling belt 105a transmits 55 gallons of steel drums that hold contact loading and unloading waste material from turning crane 99, by comprising ultrasonic and first Characteristics Detection station radiation detector (not shown), enters the loader mechanism 110.1 of powerful compacting machine 110.110 pairs of 55 gallons of steel drum containers of powerful compacting machine apply 500 to 1200 tons pressure, thereby steel drum container is reduced into the high density " cake " 117 of density between 60 to 70 pounds/cubic feet.In optimum implementation, generally use 600 tons compaction force.High density cake 117 is released from powerful compacting machine 110, slide on the compacting machine travelling belt 105b from slideway 111.2, travelling belt 105b transfers cake 117 is moved easily, has equipped ultrasonic equally and the Characteristics Detection station 107b radiation detector (not shown) through second.Then travelling belt 105b is sent to high density cake 117 on the magnetic or Vacuum hoister 116 of turning crane 114, and hoister 116 hangs in cake 117 in the composite can 200 that transports grouting station 118 to.Contain liquid when Characteristics Detection station 107a detects (a) steel drum 97, (b) wall of steel drum 97 breaks, or the waste material that (c) holds in the steel drum 97 can not compress 106 entrys into service of repair operation travelling belt.If detect a kind of in these three kinds of situations, then only need operating personnel's (not shown) that steel drum 97 is shifted onto on the repair operation travelling belt 106 from compacting machine travelling belt 105a, the latter then steel drum 97 is sent between repair operation 112, carry out there that suitable bucket wall is repaired, liquid solidifies or independently grouting formality in the bucket, so that make steel drum 97 and the waste material that holds reaches the proper states that is sealed in the composite can 200.If obstructing event occurs in 112 between repair operation, steel drum 97 can temporarily leave adding a cover of loading place 85 of contact in to be deposited in the well 113.
Describe Fig. 2 now in detail.As shown in the figure, powerful compacting machine 110 of the present invention comprises a charge mechanism 110.1, and there is a steel drum scraper bowl in this mechanism at the end of articulated type telescopic boom device 110.3.Slide the steel drum 97 of skewed slot at the end of compacting machine travelling belt 105a, the personnel of being operated send in the steel drum scraper bowl 110.2.Then articulated type telescopic boom device 110.3 is steel drum 97 skid bed 110.4 of packing into.Compacting machine 110 also comprises a charging pressure head 110.5, and it is sent into steel drum 97 within the telescopic compacting tube 110.6, and compacting tube 110.6 can be mobile between the position of main pressure head 110.8 outsides and discharging slideway 111.2 tops.In Fig. 2, compacting cylinder 110.6 is illustrated in and leaves main pressure head 110.8 and the extended position at contiguous discharging slideway 111.2 tops.After steel drum 97 was packed compacting tube 110.6 into, compacting tube 110.6 was withdrawn in the main pressure head 110.8, and steel drum 97 is not shown at pressure head piston 110.9(there) and the press of main pressure head 110.8 between flatten.As previously mentioned, one 500 to 1200 tons compaction force is added on the steel drum 97.Utilize big like this compaction force that three tangible benefits are arranged.Therefore the first, the volume of steel drum 97 and contained object thereof dwindles, and makes a composite can 200 more a plurality of steel drums of can packing into.Say exactly, use big like this compaction force can make 35 to 84 steel drums 97 be encapsulated into a composite can 200, rather than 14 steel drums.Second, distantly be to use steel that big like this compaction force makes bucket 97 to surmount the elastic limit of material far away, therefore with the waste material that includes, the high density cake that forms can not " rebound " again and arrive bigger shape after discharging from discharging slideway 111.2.Eliminated this " rebounding ", just eliminated the possibility that after composite can 200 is packed cake 117 and grouting into, in the hardened mortar of composite can 200, forms cavity or internal rupture.Except eliminating " rebounding ", the high density cake 117 that causes is when covering mortar, and in positive incompressible enhancing structure of composite can 200 inner formation, the another kind that its helps composite can to play the structural support component of ground trench overlayer 164 is employed.At last, the height compacting (waste material is generally rag, paper and contaminated working cloth) of waste material makes waste material no longer absorb water in the steel drum 97.Certainly, this makes waste material in they are got wet this few event really, is not easy to leach radiomaterial.This to absorbing the resistance of water, also make waste material be not easy to produce biological degradation, this has replenished the full functionality of composite can 200 aspect the sealing waste material again, because the meeting after for a long time of this biological degradation " depletes of " container of shipment waste material, and causes the sinking problem.
The end should be mentioned that compacting machine 110 comprises an air filtering system 111.4, and it has 111.6, one exhaust ducts 111.7 of 111.5, one blowing plants of a filtrator.Air filtering system 111.4 is owing to applying the radioactivity suspended particulates that 660~1100 ton forces produce and discharge transporting the steel drum 97 that can contact waste material.
Get back to Fig. 1, the loading place 85 of facility 1 comprises a grouting station 118, it has a mortar-trough that can extend 120, and this groove can inject mortar and be limited to rail set 66a(near remote control loading and unloading garbage area 3) or rail set 66b(near contact loading and unloading garbage area 85) railcar 64 on composite can 200 in.Noncontact loading place 3 and the composite can 200 that contacts loading place 85 loadings are all used a grouting station 118, and another has avoided the repetition of expensive components in the total system.Grouting station 118 and then one comprise transport crane 126 add a cover station 122, crane 126 has a hoister 128, is used for lid 220 is mentioned above the top of the composite can 200 that enters the process of adding a cover.When introducing the structure of composite can 200 in detail, the process of adding a cover will be described more accurately.
Though composite can 200 is usually near the filling waste material in the waste material packaging facility 1 in waste disposal place 150, grouting (at grouting station 118) with add a cover, they also can be handled in waste material produces the facility on ground.Because the surface emissivity of the composite can that obtains at last is usually low to can contacting loading and unloading, so composite can 200 scene storage and wouldn't utilize the disposal space easily.When disposing the space can utilize the time, composite can 200 can be transported to disposal site 150 in reusable transition cask (not shown), and directly is deposited in the trench 152 and goes.Though this method does not preferably adopt, it is usually than using on-the-spot waste material storage facilities will spend less.
The disposal site 150 that Fig. 3 explanation is used in combination with packaging facility 1.Disposal site 150 is usually by the perhaps a plurality of parallel trenches of trench 152(with general smooth alluviation ground 154) constitute.Before the composite can with cover 200 that mortar has been hardened is packed trench into, in whole ground 154, place the lisimeter 155 of many collection water equably, with the radiation level of water in the monitoring trench.The placement way of lisimeter 155 in trench ground 154 is in hole of brill, ground, the slender tube body of lisimeter to be inserted.The operating personnel that plastic tube networking (not shown) makes disposal site 150 sucking-off termly are collected in water in the cup of lisimeter 155, monitor the radiation level of these water samples termly, to determine whether radiant matter leaks out slightly from composite can 200.All ground 154 are suitably buried put lisimeter 155 after, ground 154 covers about 2 feet thick sandy gravel stratums 156, sandy gravel stratum plays the capillary restraining barrier.Even disposal site 150 preferably is chosen in the place that groundwater flow is lower than 154 80 feet on trench ground at least, gravel capillary restraining barrier 156 also still is placed on the top on ground 154, prevents that to provide underground water is penetrated into the additional assurance of going the stacking array 160 of composite can 200 owing to capillary action from trench ground 154.Though the whole capillarys restraining barrier in the disposal site 150 of the present invention preferably is made of gravel, it should be noted that, present invention includes and use the high coarse grain shape material of transmissibility.Sandy gravel stratum 156 has covered about 4 inches thick filling sand beds 158.This filling sand bed 158 plays roadbed, is used to support the wheel of heavy fork truck 185 and trailer 184, and fork truck 185 and trailer 184 are used for a composite can 200 fortune and remove trench 152.If there is not sand bed 158, vehicle 184 and 185 wheel can be absorbed in the sandy gravel stratum 156 and going.
The next parts of disposal site 150 are closely packed arrays 160 of sexangle composite can 200 illustrated in fig. 3.In optimum implementation, composite can 200 is preferably stacked into cylindricality close to each other, each Six Point of each composite can 200 all with the Six Point copline of two composite cans in addition that forms cylindricality.Composite can is arranged in this kind cylindricality close to each other, has four tangible benefits at least.The first, this kind closely packed of composite can 200 can provide supporting structure for non-hard trench overlayer 164, and the natural materials that overlayer 164 can be flowed by soil, sand and gravel and so on rapidly easily forms.The second, this kind is arranged in does not almost completely have the space between the composite can 200, the soil shrinkage problem that discussed before may causing originally in this space.The 3rd, this kind arranged even can be withstood serious seismic disturbance, because each composite can 200 can (being end face, bottom surface and six sexangle sides that form composite can 200) be done independent different motion along eight different planes.Because there are the rigidity interlocking in neither one composite can and adjacent composite can, so each composite can be done the motion of certain vertical slip or horizontal slip at least in the seismic disturbance incident.The freedom of motion on this eight planes makes whole composite can array 160 adapt to the change of shape of trench 152 neatly, and eliminates or reduce at least as far as possible to produce in array 160 possibility of local earthquake's disturbance of local stress point.This stress point strength is broken even as big as the wall that makes entire container.The 4th, the column of using in the array 160 is stacked, and makes when taking place to need to reclaim the accident of composite can, is easy to reclaim specific composite can 200, because as long as want comprising composite can particular combinations jar post above dig the hole of a composite can size, just can take out any one composite can.In optimum implementation, i.e. " the hottest " composite can 200 that radioactivity is the strongest places the bottom of composite can array 160, the composite can more weak by radioactivity surrounds, and therefore the composite can around and the composite can of middle layer and top layer will provide additional shielding to the radiation that material in " heat " composite can sends.
Trench 152 also comprises side gravel capillary restraining barrier 162a and 162b, and they are between the wall of closely packed composite can array 160 and trench 152.The purpose of these restraining barriers 162a and 162b is again anti-sealing from the infiltration around the closely packed array 160 of composite can 200 of the wall of trench 152.In optimum implementation, each side capillary restraining barrier 162a and 162b be about 2 feet thick.
The non-rigid overlayer that preferably a kind of natural materials that is flowed by soil, sand and gravel and so on of trench overlayer 164 forms.A kind of like this composite structure of overlayer specific rigidity more can stand seismic disturbance.In particular, if seismic disturbance takes place, cause between the Different Strata of overlayer 164 vertical minute movement takes place, then overlayer 164 non-rigid makes its at least can part " self-healing ".In addition,, utilize conventional repairing the roads and shoveling equipment so, just can easily repair overlayer 164 if cause the serious seismic disturbance of the quite big damage of overlayer 164.As noted earlier, the closely packed array 160 of composite can provides all essential structure supports for the structure and the maintenance of the Different Strata of trench overlayer 164.
The ground floor of trench overlayer 164 is one deck atteration 166 preferably, and its thickness range is thick from 4 feet on the limit thick to central authorities 7 feet.As pointing out among Fig. 3, its local soil of preferably shifting out when excavating trench 152 of alluvial deposit 166(forms) be to slide to both sides gradually with about 4.5% gradient from center line.A kind of like this appearance profile makes overlayer 164 rush down the outer field water of infiltrate overlayer 164 down effectively, these water is guided into the drainageway 178a and the 178b of ditch side.After alluvial deposit 166 is added to above the top of closely packed composite can array 160,, then place other each layer with soil layer 166 compactings.This compacting can be carried out with the subgrade compaction equipment of routine, also can allow alluvial deposit 166 only be subjected to the natural force effect fully and stablizes.These two kinds can the method for compacting alluvial deposit 166 in, preferably use subgrade compaction equipment.Even it is faster that the atteration natural stability time among the present invention was compared with the soil stabilization time in waste disposal place in the prior art, also still seldom be shorter than three months, also may reach 1 year, depend on the character of the specific soil that constitutes atteration.In contrast, if use path pressuring equipment, can shorten to about several days stabilization time.Should be noted that alluvial deposit 166 is placed into the speed on the closely packed array 160, the speed that forms array 160 with stacking single composite can 200 is similar to.This alluvial deposit 166 is placed on way on the composite can array 160 simultaneously, the radiant quantity that pick ditch workman is subjected to when building up disposal site 150 reduces to minimum.
Approx after the compacting, apply the about 4 inches filling sand bed 168 of a layer thickness at alluvial deposit 166 above.After sand bed 168 is added on the alluvial deposit 166 fully, on filling sand bed 168, place the about 2 feet gravel capillary restraining barrier 170 of another layer thickness.Filling sand bed 168 serves as the insertion restraining barrier between the atteration quite thin in the quite thick gravel that forms gravel capillary restraining barrier 170 and the alluvial deposit 166.One after place on gravel capillary restraining barrier 170, and the filling sand bed 172 that another road thickness is about 4 inches is added on the gravel capillary restraining barrier 170.Secondly, the fine powder sand 174 of one deck water pouring is added on the filling sand bed 172 of imbrication on gravel capillary restraining barrier 170.Filling sand bed 172 serves as the insertion restraining barrier between the gravel on the silty sand of silt layer 174 and gravel capillary restraining barrier 170 again.Silt layer 174 is main water pouring layers of trench overlayer 164, and about 2 feet of thickness is formed by the material that sieved (preferably being obtained by the locality), and compacting on the position should arranged.Use silt layer 174 to replace having two aspect benefits at least as other water pouring natural materials of clay and so on.At first, silty sand usually obtains from the locality than clay is easier, so expense is lower.Secondly, if silt layer 174 saturated water, can be as clay when its is dry uneasy split or broken do not produce and splits or fragmentation, helps to keep the general integrity of trench overlayer 164.
The edge of silt layer 174 adjoins the drainageway 178a and the 178b of trench 152 both sides.Drainageway 178a and 178b respectively have a groove, have settled antipriming pipe 182a and 182b in the groove.The water that flows down from silt layer 174 both sides injects pipe 182a and 182b by eyelet, and flows along trench drain 180a and 180b, leaves trench 152.If rainwater or other surface water source are very many, so that silt layer 174 is saturated by water institute fully, gravel capillary restraining barrier 170 will prevent that sealing flows into composite can array 160 by capillary action downwards from saturated silt layer 174.
The top one deck 176 of trench 164 is to be made of the riprap layer that gradient is arranged, and says with popular words, is extremely thick gravel (it can be big or small as fist stone).Riprap layer 176 plays three functions at least.The first, its insulating powder sand bed 174 is avoided degrading gradually of wind and flowing water.The second, it provides last one radiation blocking layer to composite can array 160, and it makes the radiation level of disposal site 150 be reduced to the scope that is positioned at normal background radiation satisfactorily.The 3rd, it provides defensive restraining barrier together, and it stops the human or animal who swarms into to pick up above composite can array 160.The optimum implementation of up to the present described overlayer 164 is used for dry area.In the humid area, another embodiment of overlayer 164 is the infiltration restraining barrier that increase by first road is made of local soil on the closely packed array 160 of composite can 200.This has covered sand bed and gravel capillary restraining barrier above layer successively, is similar to 168,170 and 172 each layers of previous discussion.These sand beds cover the cobble insert layer again successively with gravel capillary restraining barrier, and additional one deck sand bed and sandy gravel stratum on the top are to support the soil that last one deck has vegetation.In a kind of like this alternate embodiment, vegetation works on the one hand to prevent that upper strata earth from may be degraded, and removes the water of infiltration overlayer top layer on the other hand.The plant of using should have shallow root, not hinder the integrality of overlayer 164.In addition, a kind of so alternative embodiment can have the above gradient of general 10 degree, is accompanied by bigger rainfall amount because consider such area.
Consult Fig. 4 A, 4B, 4C and 5A, 5B now, composite can 200 of the present invention generally is made up of container 201 and lid 220, and container 201 has the wall of reinforced concrete, it fill nuke rubbish and suitably grouting after, cover with lid 220.
At length consult Fig. 4 A to 4C now.The container 201 of composite can 200 is sexangle prisms 202, and inner 216 is drum shape.The corner angle 204 at the sexangle wall place of abutting one another are preferably clipped, so as after composite can 200 to be stacked into composite can array 160 illustrated in fig. 3 near composite can 200 between also leave little space.These little spaces are even as big as holding recovery instrument (reclaiming the words of any one composite can 200 if desired), but the little remarkable sinking that does not produce soil when being arranged in the illustrative planform of Fig. 3 when composite can.Secondly, when the cross sectional shape of corner angle 204 made in stacking process and with fork truck 185 composite can 200 to be pushed the composite can array, corner angle were not easy cracked damage.
