Containment structure of floating nuclear power plant

Abstract

The invention relates to a containment structure of a floating nuclear power plant. The containment structure includes a containment body, and is characterized in that the containment body is internally equipped with a loop area and a refueling area, the loop area includes a main coolant system compartment and a loop subsystem compartment that area interconnected, a steam generator and a voltage stabilizer of the main coolant system are arranged on one side close to the containment front wall, a loop subsystem is disposed in the compartments on both sides of a suppression water tank, the refueling area includes a spent fuel storage pool, a suppression pool and a reactor chamber, the suppression pool is located between the spent fuel storage pool and the reactor chamber, the suppression pool, sluice gate equipped partition walls are disposed between the suppression pool and the spent fuel storage pool and reactor chamber respectively, discharge pipelines are laid vertically in the wallbetween the loop subsystem compartment and the suppression pool, and the upper ends of lower ends of the discharge pipelines are respectively connected to the loop subsystem compartment and the suppression pool. The containment structure of a floating nuclear power plant provided by the invention has the advantages of compact structure, reasonable layout, good suppression effect, simplification ofrefueling process and improvement of refueling safety.

Description

technical field [0001] The invention relates to a containment vessel of a nuclear power plant, in particular to a containment vessel structure of a floating nuclear power plant. Background technique [0002] The nuclear-powered icebreakers that Russia has built and the nuclear-powered merchant ships that have been built in the United States have no refueling-related cabins and facilities for the nuclear power devices of these ships, and the nuclear power devices occupy a small space. These ships have good navigability and can operate in a wide range of sea areas. [0003] The floating nuclear power plant under construction in Russia has the capability of autonomous refueling, adding spent fuel storage compartments and refueling compartments. The nuclear power plant-related facilities occupy a large space and the ship is relatively large. Its floating nuclear power plants have high requirements on marine environmental conditions, and usually operate on the shore with breakwa...
