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.
