Description

Technical Field

[0001] The invention relates to the technical field of nuclear power plant building layout, and in particular to a layout structure for arranging nuclear power plant buildings by utilizing abandoned mines. Background Art

[0002] A nuclear power plant is a power plant that converts the energy generated by nuclear fuel in fission reactions into electrical energy. Its working principle is that nuclear fuel undergoes fission reactions in the reactor equipment to generate a large amount of heat energy, which is then taken out with high-pressure water to generate steam in the steam generator room. The steam is transmitted to the steam turbine generator set, and the steam after power generation is condensed and returned to the steam generator. Nuclear power plant buildings are generally divided into two parts: the nuclear reaction plant that uses nuclear fission to produce steam, and the power plant that uses high-temperature steam to drive the steam turbine to generate electricity.

[0003] However, ground nuclear power plants encroach on farmland, pose a certain threat to the surrounding environment, and have shortcomings in safety protection. Therefore, the development of deep underground nuclear power plants uses natural and solid barriers to deal with external natural disasters such as wind, tsunamis, floods or man-made disasters, terrorist attacks, weapon attacks, etc. The defense capabilities are far superior to traditional ground nuclear power plants, and the possibility of releasing large amounts of radioactive substances is actually eliminated from the design. Therefore, the present invention is based on the utilization of abandoned mines combined with the safety protection of nuclear power plants, and provides a layout structure for accommodating nuclear power plant buildings using abandoned mines. Summary of the invention

[0004] Aiming at the problem that the safety protection measures of ground nuclear power plants are poor and a large area of ​​land is occupied, the present invention provides a layout method of an underground nuclear power plant in an abandoned mine.

[0005] The present invention is realized by the following technical scheme: a layout structure for placing a nuclear power plant building using an abandoned mine, comprising a ground control room, a power plant building placed at the first level, and a nuclear reaction plant building placed at the second level:

[0006] The ground control room is used to dispatch personnel for safe operation, equipment transportation and production in each plant;

[0007] The first level power plant specifically includes a steam turbine generating room, a cooling room, and an inspection passage. The steam turbine generating room is connected to the second level steam generating room through a steam pipeline, and communicates with the cooling room and the transport shaft through the inspection passage.

[0008] The second-level nuclear reaction plant specifically includes a nuclear reaction room, a water storage room, a steam generating room, an equipment storage room, a disaster shelter, a monitoring room, and an equipment passage. The steam generating room is located in the center of the second level. The nuclear reaction room provides energy to heat the water in the water storage room to generate steam. The monitoring room monitors the situation in each plant in real time. The equipment storage room is used to place operation and maintenance equipment. The disaster shelter is located behind the equipment storage room, away from the nuclear reaction room, and is used for emergency evacuation and disaster avoidance.

[0009] Furthermore, each of the factory buildings is constructed in the goaf, and after construction is completed, slurry is filled between the broken gangue for reinforcement.

[0010] Furthermore, a containment shell is installed on the surface of each building of the second-level nuclear reaction building to prevent the migration of nuclides.

[0011] Furthermore, each factory building entrance and exit is provided with an isolation door, and the isolation door adopts a double-layer airlock door design.

[0012] Furthermore, an artificial blasting device is installed at the bottom of the first level to seal the second level in an emergency. BRIEF DESCRIPTION OF THE DRAWINGS
