Description
Technical field
The present invention relates to a kind of tent assembly that in the process nuclear field of materials, uses.The invention particularly relates to a kind of nuclear radiation protection property and disposable tent assembly, glove box (glove box) for example, this assembly is used for the radiocontamination thing is intervened (intervention), is under the environment of sealing, to carry out thereby make said intervention.Said tent assembly comprises at least one can and outer support member.This intervention for example comprises dismounting and the overhaul to nuclear device.
Background technology
Nuclear device usually need to intervene-have and discharge active material and the risk that exposes α, β and/or gamma-rays and/or neutron at their certain time point-open said nuclear device in serviceable life at this time point.
Nuclear device for example mixed oxide fuel (' MOX) or other contain plutonium fuel production device factory harbour, for example pollute glove box, consume fuel that β/gamma-electric cell and α/β/gamma-electric cell are handled again, are used to produce the fresh fuel that comprises a small amount of actinide.
Wherein a kind of intervention is meant scrapping of nuclear device.Scrapping can be to whole device, and for example after nuclear device cut out, scrapping also can be part, when for example the part of said nuclear device need be reequiped, or in the length of life of said device for prolonging.
Overhaul is another kind of the intervention, opens nuclear device and has the risk that discharges pollutant.When for example changing large-scale or heavy process components or window, follow abandoning of process components to reduce sometimes and the destruction of the nuclear technology shell that pollutes with size.
Between intervention period, for example scrap and overhaul, take multiple preventive measure to reduce the release of radiocontamination particle and the risk that human body is shone.The operator personnel not only need be to taking in and sucking these radiocontamination particles and the internal radiation that causes protects; External radiation from radiation when also wanting is protected, and for example radiation surpasses the control dose limit and/or reaches the (" amount that the floor level ") principle that can rationally accomplish is confirmed according to ALARA.Thereby the result is that before said intervention, the nuclear fission material is collected usually and is removed from nuclear device.Thus, generally speaking the exposure of fission neutron is insignificant.Can on the maximum reasonable degree, remove nuclear pollution subsequently.Another kind of prevention provides the intervention shell, for example Alpha's containment member, glove box or disposable protective tent assembly, said protective tent assembly be positioned at need to remove or the nuclear device of service around.
When Alpha's containment member or glove box are used as the intervention shell, said nuclear device (for example said glove box) at first need be transported to the enclosure space that is positioned at the factory somewhere.Yet, consider the exposure of radioactive particulate, this transportation is expensive and has risk.
Said nuclear device gets into shell and realizes through " pack " technology of using a kind of routine.The technology of back can keep said casing when introducing equipment or other materials sealing.For above-mentioned purpose, said equipment or material are set in the sack, and wherein open side provides O type circle.The latter is fixed in the circumferential groove of inlet of said enclosure space, thereby makes this sack overlapping and close the latter with another sack of porch Already in.In order to get into said equipment or said material, the latter is drawn in the enclosure space together with said sack.In case said equipment or material are positioned at wherein, said inlet is closed by said sack, and storage has equipment or material in the sack.
Said shell holds intervenes required equipment, and is under the state of relative external environment condition sealing.Stand in the inside of Alpha's containment member or in cutting box outside operator's electrical power for operation or pneumatic aid, for example removal tool.Said operator's entrance and exit is through the perception in advance of adaptive gas lock, and the discarded part that cutting operation causes removes through using waste storage drum or cutting box near said Alpha's containment member.
When in Alpha's containment member, working, the operator is equipped with seal coat and breathing apparatus.Can wear lead apron when being exposed to gamma-rays following time.
For fear of the risk that said nuclear device is transported to out of bounds areas and expense that is produced and exposure, recorded and used a kind of protective tent equipment, for example be patented claim and the paper " art is put forward in the dismounting that is used for plutonium pollution glove box: from the experience that stopped production 1 year " of DE4040115t6 at publication number; R.BAUMANN, P.FABER, the 6th radiates and scraps refuse international symposium; Kontec 2004; Berlin, Germany, in March, 2004.
Described glove box in the document of back and how to be transported to the protective tent assembly that is positioned at operation factory, said protective tent assembly is erected at around the said glove box at the scene.Said protective tent assembly comprises flexibility and envelope sealed, and said shell is adapted by the form factor of special one-tenth and the said glove box that will remove, and can be equipped with gloves and window, and passes through the ventilating system maintenance vacuum of oneself.Said tent assembly can comprise the cutting equipment that is used to carry out dismounting, and said cutting equipment moves under the situation of isolating with external environment condition.The operator who stands in said protective tent assembly outside operates said removal tool.Similar instrument and watch-dog when these operators can equip with the operational sequence glove box.The refuse that said cutting operation produces can be discharged through the waste storage drum that links to each other with protective tent assembly with sealing means.
The shortcoming of said known protective tent assembly is that its radiation protection to the operator is not enough.In fact, the uranium/plutonium that is produced by plutonium 241 decline and the β of americium 241 expose with gamma-rays, the neutron exposure that nuclear reaction produces in particularly most of nuclear device and the risk of generation can not be underestimated.
Therefore, need dismounting or the process equipment of serving and its shell by highly polluted when said, the operator prevents to expose through wearing suitable clothes, comprises lead apron of the prior art.Yet lead apron has this shortcoming down: they can not reduce the dose rate of neutron to the operator who is wearing it, only can prevent gamma-rays.In addition, these lead aprons are heavy, restriction operation person's dirigibility, and bring added burden when in known protective tent assembly, carrying out cutting work physical demands and dangerous for the operator.
Summary of the invention
