Detailed Description
For a clearer understanding of technical features, objects and effects of the present utility model, a detailed description of embodiments of the present utility model will be made with reference to the accompanying drawings.
Through theoretical analysis and actual measurement, the waste water in the radioactive waste disposal karst cave system is mainly divided into two types, namely dialysis water in non-radioactive mountain bedrock cracks, and the part of waste water mainly enters the vicinity of a disposal area in the form of original or external rainfall and the like in mountain bodies, and is not in contact with radioactive waste cargo bags, so that the waste water does not have radioactivity; the other is that during ventilation of the disposal chamber, condensed water drops may be dropped on the surface of the radioactive waste bag at the top of the disposal area due to condensation caused by temperature difference between the inside and the outside of the mountain, and the water contains potential radioactivity due to contact with the radioactive waste bag. The waste water to be discharged from the cave can be classified into potentially radioactive waste water and non-radioactive waste water.
As shown in fig. 1 to 4, the radioactive waste disposal cave system of an embodiment of the present utility model includes a disposal cave, a potentially radioactive waste water collection line located inside the disposal cave, and a potentially radioactive waste water collection container 1 located outside the disposal cave. The disposal cavern includes a traffic cavern 20, a radioactive waste disposal cavern 21, a construction cavern 22, and a ventilation cavern 23, which are respectively communicated with the traffic cavern 20. Arrows in fig. 1 show the flow direction of wastewater in the disposal of the cave.
The potentially radioactive waste water collection container 1 is provided corresponding to the entrance/exit of the traffic cavity 20, and is used for collecting potentially radioactive waste water flowing out from the entrance/exit of the traffic cavity 20. The potentially radioactive waste water collection line extends along the length of the transportation chamber 20 with its inlet end 9 at the junction of the transportation chamber 20 and the radioactive waste disposal chamber 21 and its outlet end connected to the potentially radioactive waste water collection container 1. As shown in fig. 4, the potentially radioactive waste water collection container 1 is provided with an interface 10 for connecting the outlet end of the potentially radioactive waste water collection line.
The internal ground level of the disposal rock opening is greater than the ground level outside the disposal rock opening. The ground of the traffic chamber 20, the radioactive waste disposal chamber 21, the construction chamber 22 and the ventilation chamber 23 is at least partially provided with a slope. That is, the ground of the traffic chamber 20, the radioactive waste disposal chamber 21, the construction chamber 22 and the ventilation chamber 23 may be provided with slopes as a whole or may be provided with slopes in part for draining potentially radioactive waste water and non-radioactive waste water in the disposal rock to the entrances and exits of the traffic chamber 20.
Specifically, the entrance/exit of the transportation chamber 20 is used as an entrance/exit of the disposal cave, and is communicated with the external surface environment, and the wastewater in the disposal cave is led out of the cave from the entrance/exit of the transportation chamber 20. The internal ground elevation of the disposal rock cave is larger than the ground elevation of the external ground surface, so that the height difference exists between the interior of the disposal rock cave and the entrance (namely the entrance of the traffic cavity 20), and the passive self-flowing discharge of the wastewater can be realized. For example, in this embodiment, the elevation inside the disposal cave is 22m, while the elevation of the ground on which the potentially radioactive waste water collection container 1 is located outside the disposal cave is 3.8m.
Under the drainage effect of the ground gradient, the potential radioactive waste water in the radioactive waste disposal cavern 21 finally enters the position of the potential radioactive waste water collecting container 1 outside the traffic cavern 20 through the potential radioactive waste water collecting pipeline, and the potential radioactive waste water in the potential radioactive waste water collecting container 1 needs to be subjected to radioactivity monitoring and then discharged after reaching the discharge standard. The non-radioactive waste water in the radioactive waste disposal chamber 21, namely mountain bedrock seepage water from the traffic chamber 20, the construction chamber 22 and the ventilation chamber 23 directly flows out to the ground surface from the entrance and exit of the traffic chamber 20 for discharge under the slope drainage effect of the chamber ground.
Therefore, the utility model has at least the following beneficial effects: the potentially radioactive waste water in the radioactive waste disposal cavern 21 is finally collected by entering a potentially radioactive waste water collection container outside the traffic cavern 20 through a potentially radioactive waste water collection pipeline, and the portion of the potentially radioactive waste water is subjected to radioactivity monitoring and is discharged after reaching the discharge standard. The non-radioactive wastewater (namely mountain bedrock seepage water from the traffic cavern 20, the construction cavern 22 and the ventilation cavern 23) in the disposal cavern directly flows out to the ground surface from the entrance and exit of the traffic cavern 20 for discharge, so that the potential radioactive wastewater and the non-radioactive wastewater can be subjected to classification treatment, the amount of collected wastewater is reduced, the required capacity of the wastewater collection equipment is reduced, the required requirement is reduced, and the workload of daily operation, sampling, maintenance and the like is reduced; the interior ground elevation of the disposal cavern is greater than the ground elevation outside the disposal cavern, and the ground of each chamber of the disposal cavern is provided with a gradient, and the potentially radioactive wastewater and the non-radioactive wastewater in the disposal cavern can flow by gravity and be discharged outwards from the entrance and exit of the traffic cavern 20.
In this embodiment, as shown in fig. 1 and 3, a water collection tank 3 is provided at the junction of the transportation chamber 20 and the radioactive waste disposal chamber 21. The inlet end 9 of the potentially radioactive waste water collection line is connected to the sump 3. The potentially radioactive waste water in the radioactive waste disposal chamber 21 flows to the water collection tank 3 to accumulate under the action of the ground gradient, and is discharged into the potentially radioactive waste water collection container 1 outside the cave through the potentially radioactive waste water collection line. Therefore, the potential radioactive waste water in the radioactive waste disposal cavity 21 can be collected to the water collecting tank 3 in a concentrated mode and then discharged through the potential radioactive waste water collecting pipeline, effective collection and concentrated discharge of the potential radioactive waste water in the radioactive waste disposal cavity 21 can be achieved, and the drainage efficiency is improved.
Further, in the present embodiment, as shown in fig. 2, a filter 4 is provided in the sump 3. The inlet end 9 of the potentially radioactive waste water collection line is connected to the water outlet end of the filter 4 and is connected to the water filtered by the filter 4. The water outlet end of the filter 4 may be at its bottom or at its side. The filter 4 can firstly separate at least impurities from the collected potentially radioactive wastewater, and can also adsorb and filter radioactive particles in the wastewater, so as to primarily reduce the radioactivity of the wastewater in the water collecting tank 3. The specific construction of the filter 4 itself, which can achieve the above-mentioned functions, is known in the art, and a person skilled in the art can choose a suitable filter 4 to achieve the corresponding purpose according to the specific situation and requirements.
In this embodiment, the ground of the traffic chamber 20, the radioactive waste disposal chamber 21, the construction chamber 22 and/or the ventilation chamber 23 is provided with a drain 5 extending along the length thereof. At least the drainage ditch 5 is provided with a slope inclined to the direction of the entrance and exit of the traffic cavity 20 on the ground of the traffic cavity 20, the radioactive waste disposal cavity 21, the construction cavity 22 and/or the ventilation cavity 23, so that the non-radioactive waste water in each cavity is collected into the drainage ditch 5 in a concentrated manner and is drained to the entrance and exit of the traffic cavity 20 through the drainage ditch 5. That is, on the ground of the traffic chamber 20, the radioactive waste disposal chamber 21, the construction chamber 22 and/or the ventilation chamber 23, a slope inclined toward the entrance/exit direction of the traffic chamber 20 may be provided in an area other than the drainage ditch 5. Specifically, under the action of gravity, water in each cave is firstly in the drainage ditch 5, and the potential radioactive waste water in the radioactive waste disposal cavern 21 is drained to the inlet end of a potential radioactive waste water collecting pipeline at the joint of the traffic cavern 20 and the radioactive waste disposal cavern 21 through the drainage ditch 5, and enters the potential radioactive waste water collecting container 1 through the potential radioactive waste water collecting pipeline; the non-radioactive wastewater in other chambers is led to the entrance and exit of the traffic chamber 20 through the drainage ditch 5 and is directly discharged to the ground surface. Therefore, the waste water in each cave can be effectively collected and intensively discharged, and the drainage efficiency is improved. The ground that can be transportation chamber 20, radioactive waste handles chamber 21, construction chamber 22 and ventilation chamber 23 all is equipped with escape canal 5, also can be transportation chamber 20, radioactive waste handles chamber 21, one or more of construction chamber 22 and ventilation chamber 23 is equipped with escape canal 5, when transportation chamber 20, radioactive waste handles chamber 21, construction chamber 22 and ventilation chamber 23 all are equipped with escape canal 5, the drainage efficiency that can realize is the highest.
Further, on the ground of the traffic chamber 20, the radioactive waste disposal chamber 21, the construction chamber 22 and/or the ventilation chamber 23, a slope inclined to the direction of the drainage ditch 5 may be provided in an area other than the drainage ditch 5 to drain water on the area other than the drainage ditch 5 into the drainage ditch 5 for concentrated collection.
Further, in this embodiment, the potentially radioactive waste water collection line is located within the drain 5 of the traffic cavity 20. From this, latent radioactive waste water and non-latent radioactive waste water are all conducted to the access & exit of traffic cavity 20 through the escape canal 5 of traffic cavity 20 and are carried out categorised emission to do not influence the effective separation of two kinds of waste water, can no longer additionally occupy traffic cavity 20 except that escape canal 5 other spaces, the pipeline overall arrangement is more reasonable. Of course, in other embodiments, the potentially radioactive waste water collecting line may be disposed at a place other than the drainage ditch 5 of the traffic cavity 20, and only the ground on which the potentially radioactive waste water collecting line is disposed has to have a slope to drain the potentially radioactive waste water in the potentially radioactive waste water collecting line to the entrance and exit of the traffic cavity 20, for example, the slope inclined toward the entrance and exit of the traffic cavity 20 may be at least partially disposed on the other ground in the traffic cavity 20 other than the drainage ditch 5 for disposing the potentially radioactive waste water collecting line. In other embodiments, when no drainage ditch is provided in the traffic chamber 20, it may be that some or all of the ground in the traffic chamber 20 is provided with a slope sloping toward the entrance and exit of the traffic chamber 20, and the potentially radioactive waste water collection line is disposed on the ground having a slope that provides drainage for both the non-radioactive waste water and the potentially radioactive waste water in the potentially radioactive waste water collection line.
Further, in this embodiment, the gutters 5 are distributed on opposite sides of the ground near the wall surface of the traffic chamber 20, the radioactive waste disposal chamber 21, the construction chamber 22 and/or the ventilation chamber 23. And the gutters 5 located at opposite sides of the ground may be symmetrically disposed. That is, the gutters 5 may be disposed on opposite sides of the ground against the wall, giving up as much central traffic area as possible to minimize the obstruction to normal traffic. At this time, the drain 5 of the radioactive waste disposal cavern 21 may be directly connected to the catch tank 3, the catch tank 3 is disposed at the drain 5 side of the traffic cavern 20, near the drain 5 of the traffic cavern 20, and a communication hole may be provided between the drain 5 side wall of the traffic cavern 20 and the bottom side wall of the catch tank 3, and then the inlet end 9 of the potentially radioactive waste water collecting line may extend into the catch tank 3 from the communication hole. Of course, in other embodiments, the gutters 5 may be in other distribution patterns.
In this embodiment, the radioactive waste disposal cave system further comprises a drain pump 6 located outside the disposal cave. The potentially radioactive waste water collection container 1 is connected to a drain pump 6. In particular, the potentially radioactive waste water collection container 1 is connected by a pipeline to the inlet end of the drain pump 6. The outlet end of the drain pump 6 may be connected to a drain pipe. As described above, the potentially radioactive waste water in the potentially radioactive waste water collection container 1 is subjected to radioactivity monitoring, and the radioactivity monitoring may be implemented by using a radioactivity detector or the like. When the radioactivity of the wastewater in the potentially radioactive wastewater collection container 1 is detected to reach the discharge standard, the drainage pump 6 is started again to drain the wastewater in the potentially radioactive wastewater collection container 1 to the external surface through the drainage pipe.
In this embodiment, the radioactive waste disposal cave system further includes a waste water treatment plant 7 disposed outside the entrance and exit of the traffic cavity 20, and the potentially radioactive waste water collection container 1 and the drain pump 6 are disposed in the waste water treatment plant 7 to isolate the potentially radioactive waste water collection container 1 and the drain pump 6 from the outside. Further, the wastewater treatment plant 7 may include a wastewater collection room 70, a wastewater discharge room 71. The potentially radioactive wastewater collection vessel 1 is placed in the wastewater collection room 70 and the drain pump 6 is placed in the wastewater discharge room 71.
Further, the number of potentially radioactive wastewater collection vessels 1 is at least two. Thus, when the water level of one of the potentially radioactive waste water collection containers 1 reaches a preset threshold, water injection to that potentially radioactive waste water collection container 1 is stopped and waste water continues to be collected by the other (or more) potentially radioactive waste water collection containers 1 to leave a reasonable container margin. The number of potentially radioactive wastewater collection vessels 1 may be determined based on the particular amount of underground cavern engineering dialysis water.
Further, a control valve is arranged on the potentially radioactive waste water collecting pipe line and is used for controlling the on-off between the potentially radioactive waste water collecting pipe line and the potentially radioactive waste water collecting container 1. When the water level of the potentially radioactive waste water collection container 1 reaches a preset threshold, the control valve is closed to stop the water injection to the potentially radioactive waste water collection container 1.
