Underground nuclear power station with low and medium radioactive waste disposal system and disposal method thereof

Abstract

The invention relates to the technical field of underground nuclear power plants, and discloses an underground nuclear power plant with a low-medium radioactive waste disposal system, which comprisesa power generation area and a waste disposal area, wherein the power generation area comprises a plurality of single-pile nuclear power systems, and each single-pile nuclear power system comprises a plurality of power plants, the waste disposal area comprises an SRTF site radioactive waste treatment facility which is connected with a power generation area traffic tunnel through a waste transfer tunnel, the bottom of the SRTF site radioactive waste treatment facility is provided with a discharge water tank communicated with a site waste water discharge system of the power generation area, the SRTF site waste discharge treatment facility is also connected with a low radioactive waste treatment tunnel, a medium radioactive waste disposal tunnel and a spent fuel dry storage area. The inventionfurther discloses a disposal method of the underground nuclear power station with the low-medium radioactive waste disposal system. According to the underground nuclear power station with the low-medium-radioactive waste disposal system and the disposal method thereof, the problem of site selection of the low-medium-radioactive disposal site is solved, meanwhile, the centralization of the waste disposal function is achieved, the excavation of a cave is reduced, and the problem of nuclear security in the process of outward transportation of radioactive waste is avoided.

Description

technical field [0001] The invention relates to the technical field of underground nuclear power plants, in particular to an underground nuclear power plant with a low and intermediate radioactive waste disposal system and a disposal method thereof. Background technique [0002] With the development of nuclear power in my country, more and more radioactive wastes are produced by nuclear power plants, and the treatment and disposal of radioactive waste has become an important factor restricting the long-term sustainable development of nuclear power in my country. [0003] The main forms of low and intermediate radioactive waste generated by the operation of nuclear power plants are radioactive waste water, waste gas and solid waste. Among them, radioactive wastewater includes process wastewater, chemical wastewater and surface wastewater; waste gas includes hydrogen-containing waste gas and hydrogen-free waste gas; solid waste includes distillation residue concentrate, radioa...
