An underground nuclear power plant with a disposal site for low and intermediate radioactive waste

Abstract

The invention discloses an underground nuclear power plant with a disposal site for low and intermediate radioactive waste, which includes a nuclear island placed in the cavern group of the nuclear island of the mountain and a conventional island placed on the ground platform outside the mountain. The reactor building, the nuclear fuel building, the safety building, the electrical building and the nuclear auxiliary building arranged around the reactor building also include the low and intermediate level waste disposal site placed in the mountain nuclear island cavern group, and the low and intermediate level waste disposal site passes through the waste The transport tunnel is connected with the nuclear auxiliary plant of the nuclear island. Combining the characteristics of underground nuclear power plants, the present invention can not only meet the disposal requirements of low and intermediate radioactive wastes, realize closed cycle of fuel, reduce possible radioactive pollution in fuel cycle process, but also realize unified planning and construction of nuclear power plants and disposal sites, cut costs.

Description

technical field [0001] The invention relates to nuclear power technology, in particular to an underground nuclear power plant with a disposal site for low and intermediate radioactive waste. Background technique [0002] The low and medium radioactive waste generated by the operation and decommissioning of nuclear power plants mainly includes activated metal waste, waste resin, waste filter elements, radioactive evaporative concentrates, etc. Compared with high-level radioactive waste, its radioactive total specific activity accounts for a small proportion, but its volume is relatively large, which requires reasonable treatment and disposal. [0003] The radioactive waste generated during the operation and decommissioning of nuclear power plants is sorted in the nuclear waste plant, and the low and intermediate level waste is solidified and packaged for temporary storage, and finally transported to the disposal site for final disposal. The nuclear fuel cycle process in the n...

AI Technical Summary

Problems solved by technology

At present, my country has built two low-intermediate radioactive waste disposal sites near the surface in Northwest China and Guangdong Beilong. During the "13th Five-Year Plan" period, it plans to build five low-intermediate radioactive waste disposal sites. The currently built and proposed disposal sites are located in nuclear power plants or Near the nuclear facility, it receives the waste transported by several nearby nuclear power plants. The nuclear power plant and the low-intermediate radioactive waste site are planned and constructed separately, and the cost is relatively high
