Terrace-buried underground nuclear power plant

Abstract

The invention discloses a terraced flat-buried underground nuclear power plant, which includes a nuclear island and a conventional island. The nuclear-related buildings of the nuclear island are placed in the cavern group of the nuclear island of the mountain, and the conventional island is placed in the first conventional island area and the second conventional island area. Above, the first conventional island area is located on the terrace platform on the upper part of the mountain slope, the second conventional island area is located on the ground platform outside the slope, and the nuclear island caverns are buried flat in the mountain slope relative to the second conventional island. The present invention is applicable to the terrain environment where there are relatively large platforms on the outside and upper part of the mountain slope, or the terrain environment where large platforms are easily formed by manual excavation on the outside and upper part of the slope, and provides a feasible overall layout for the construction of underground nuclear power plants; mainly Compared with ground nuclear power plants, the process system does not require major adjustments, which reduces the difficulty of technology research and development of underground nuclear power plants; by arranging nuclear island plants in different underground caverns, it can ensure that the existing underground engineering technology meets the requirements of nuclear power plants for nuclear-related buildings to be placed underground.

Description

technical field [0001] The invention relates to nuclear power technology, in particular to a terrace-buried underground nuclear power plant. Background technique [0002] At present, large-scale commercial nuclear power plants are arranged on the ground, and the power of a single reactor is generally above 600MW. The building mainly includes two parts: the nuclear island (including the reactor device and the primary circuit system) and the conventional island (including the turbogenerator system, cooling tower, etc. auxiliary equipment, etc.). The Chernobyl nuclear accident in the former Soviet Union, the Three Mile Island nuclear accident in the United States, and the Fukushima nuclear accident in Japan have shown that the existing ground nuclear power plants are not enough to effectively prevent and control nuclear leakage and ensure nuclear safety under extreme accident conditions. For this reason, some scholars at home and abroad have proposed to build nuclear-related b...

AI Technical Summary

Problems solved by technology

However, the excavation of underground caverns is generally selected in mountainous or hilly terrain environments, and the construction environment is quite different from that of ground nuclear power plants; and the nuclear islands of ground nuclear power plants and conventional islands are arranged in close proximity, with many buildings and large sizes. Space technology is difficult to accommodate all the buildings of the nuclear island in a single artificial underground cavern, and the overall layout of the ground nuclear power plant cannot meet the needs of the construction of an underground nuclear power plant
