Main machine hall group arrangement method of nuclear power plant

Abstract

The invention discloses a main machine hall group arrangement method of a nuclear power plant and relates to the technical field of nuclear power, and the main machine hall group arrangement method is used for solving the problem that an compact and efficient arrangement method capable of meeting enabling and non-enabling safety facility arrangement requirements, which is used for solving the reasonable equipment arrangement of a nuclear island plant does not exist in the prior art. The scheme provided by the invention is as follows: according to the main machine hall group arrangement method of the nuclear power plant, a main machine hall group comprises a nuclear island and a conventional island, and a nuclear island machine hall group comprises a reactor machine hall with a double-layer safety shell, an electric machine hall, a safety machine plant, a fuel machine hall, a nuclear auxiliary machine hall, a nuclear waste machine hall, an operation service machine hall, an emergency diesel generator machine hall and a nuclear-island fire-fighting water machine hall. According to the nuclear-island machine hall group arrangement method, a novel nuclear power plant single-pile arrangement structure is adopted and comprises an enabling and non-enabling combined safety system, has stronger capability of resisting severe external events, meets the requirement of a third-generation nuclear power technology, is beneficial to improvement on the safety of the whole nuclear power plant, and can be used for enhancing the nuclear safety acceptability of the public.

Description

technical field [0001] The invention belongs to a method for arranging production workshops, in particular to a method for arranging main workshops of a nuclear power plant. Background technique [0002] At present, nuclear power plants that have been built and are under construction are mainly divided into two types of layout structures: double reactors and single reactors, especially the third-generation nuclear power units are all arranged in single reactors. The main building group of a nuclear power plant mainly refers to the nuclear island and the conventional island, and the nuclear island includes the reactor building and surrounding buildings, which are used to contain the nuclear reactor and nuclear auxiliary facilities. Restricted by the technical route, the layout methods of the main building groups of existing nuclear power plants are very different, some mainly meet the needs of redundant active safety systems (such as EPR), and some mainly meet the needs of pa...

Problems solved by technology

[0004] The layout structure of the nuclear island powerhouse targeted by the present invention is a product designed correspondingly according to the reactor technology and safety technology route, that is, "what kind of technology determines what kind of powerhouse". The double-stack layout, this layout structure can hardly be further improved to meet the requirements of the third-generation technology for the layout space location, and the nuclear island plant corresponding to the third-generation nuclear power such as AP1000 with passive safety design is simple in scale and small in size. The nuclear island plant corresponding to EPR, which is more focused on redundant active safety design, is characterized by multi-series safety plants, all of which have obvious technical tendencies, which also lead to differences in the layout and structure of the nuclear island plant
