Double-reactor T-shaped nuclear power plant group integrally provided with low-intermediate-level waste disposal field

Abstract

The invention relates to the technical field of underground nuclear power plants, and discloses a double-reactor T-shaped nuclear power plant group integrally provided with a low-intermediate-level waste disposal field. The plant group comprises a disposal field, two reactor plant cavities and a combined plant cavity; the combined plant cavity comprises a safety plant, a fuel plant, a safety plantand a nuclear auxiliary plant which are sequentially arranged from outside to inside along the space of the underground cavity; the disposal field communicates with the nuclear auxiliary plant; eachof the reactor plant cavities is connected with an electric plant cavity and a pressure relief cavity; the reactor plant cavities, the electric plant cavities and the pressure relief cavity are all indouble-reactor T-shaped mirror arrangement with the axes of the combined plant cavity as a center; and the reactor plant cavities are both connected with fuel plant, the safety plants and the nuclearauxiliary plant. According to the double-reactor T-shaped nuclear power plant group integrally provided with the low-intermediate-level waste disposal field, the whole excavation amount of underground cavities is reduced, the problem of disposal of low-intermediate-level wastes after operation and decommissioning of nuclear power plants is solved, and whole economy is improved.

Description

technical field [0001] The invention relates to the technical field of underground nuclear power plants, in particular to a double-stack T-shaped nuclear power plant building group integrated with low and intermediate radioactive disposal sites. Background technique [0002] With the development of domestic nuclear power, nuclear power sites are becoming more and more scarce resources. Due to the importance of nuclear safety and my country's special national conditions, the development of ground sites is very limited. On the other hand, people have turned their attention to the underground space. [0003] China's utility model patent application (publication date: November 26, 2014, publication number: CN203966573U) discloses an underground nuclear power plant in which the reactor and radioactive auxiliary plants are placed underground. The layout of the cavern and the scale of excavation are explained. Putting the nuclear power plant underground can give full play to the p...

AI Technical Summary

Problems solved by technology

At present, the Northwest Disposal Site and the Guangdong Beilong Disposal Site have been built in China, and five low and intermediate radioactive disposal sites are planned to be built during the 13th Five-Year Plan period. Most of the radioactive waste generated by nuclear power plants is still temporarily stored in nuclear power plants, which affects the normal operation of nuclear power plants
