A design method for the fully buried layout of the main building group of an underground nuclear power plant

Abstract

The invention discloses a fully-buried layout design method for the main workshop group of an underground nuclear power plant, which comprises arranging the reactor workshop cavern at the geometric center of the plane area occupied by the underground nuclear island cavern group of a single nuclear power unit; the steam turbine generator workshop cavern The location of the room layout should make the distance L1 of the straight line section of the anti-main steam pipeline satisfy L1≦400m; the minimum distance formula for the distance between the main cavern group of the underground nuclear island, the underground conventional island and the main cavern group between them is proposed; When islands and nuclear islands are arranged underground, the requirements for the thickness of the rock and soil mass on the top of the reactor building cavern and the top of the loading and unloading powerhouse cavern. The invention successfully solves the technical problems of separating the nuclear island and the conventional island underground of the nuclear power plant and how to determine the positional relationship between the underground nuclear island and the underground conventional island, and the position of the main powerhouse group, and provides a reasonable and convenient way to determine the underground nuclear island and underground of the underground nuclear power plant. Reasonable spatial position relationship among conventional islands and the fully buried layout design method for the location of the main factory buildings in each part of the area.

Description

technical field [0001] The invention relates to a layout design method of production workshops, in particular to a fully buried layout design method of main workshops of an underground nuclear power plant. Background technique [0002] As society pays more and more attention to nuclear safety, especially after the Fukushima nuclear accident in Japan, countries around the world are prompted to reassess and review their nuclear power plant safety and nuclear energy planning, and further improve human understanding of nuclear energy development. The ability of existing nuclear power technology, including third-generation nuclear power technology, to resist severe external events (such as tsunamis, earthquakes, and large aircraft crashes, etc.) has also been questioned by the public. [0003] With the help of modern underground engineering technology and the practical experience of large-scale hydropower underground power plants, moving the nuclear power plant to the mountain ca...
