Slope type horizontally-buried underground nuclear power station

Abstract

The invention discloses a slope type horizontally-buried underground nuclear power station which comprises a nuclear island and a conventional island. A nuclear-related building of the nuclear island is arranged in a nuclear island cavity group of a mountain. The conventional island is arranged on a ground platform on the outer side of the mountain. The nuclear island cavity group is horizontally buried in a slope of the mountain relative to the conventional island. The slope type horizontally-buried underground nuclear power station is suitable for a terrain environment where a large ground platform is arranged on the outer side of the slope of the mountain or a terrain environment where a large platform can be formed easily by hand excavation on the outer side of the slope of the mountain; a feasible overall layout is provided for construction of the underground nuclear power station, the engineering economy is good, and the platform on the outer side of the slope is beneficial to construction and arrangement; a main process system does not need large adjustment relative to a ground nuclear power station, so that the technical research and development difficulty of the underground nuclear power station is lowered; since nuclear island plants are arranged in different underground cavities, it can be ensured that the existing underground engineering technology meets the requirement that the nuclear-related building of the nuclear power station is arranged underground.

Description

Technical field [0001] The invention relates to nuclear power technology, in particular to a slope-type flat-buried underground nuclear power plant. Background technique [0002] At present, large-scale commercial nuclear power plants are all arranged on the ground. The power of a single reactor is generally above 600MW. The buildings mainly consist of two parts: nuclear island (including reactor equipment and primary circuit system) and conventional island (including steam turbine generator system, cooling tower, and others). 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-based nuclear power plants are insufficient to effectively prevent and control nuclear leakage and ensure nuclear safety under extreme accident conditions. For this reason, some scholars at home and abroad proposed to construct nucl...

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
