Abstract

The invention discloses a floating nuclear power station reactor compartment arrangement structure which comprises a double-shell ship body arranged on an offshore nuclear power platform, wherein a primary containment vessel and a spent fuel storage cabin are arranged in an inner cavity of the double-shell ship body; a reactor and primary loop system equipment are arranged in the primary containment vessel; a spent fuel storage facility is arranged in the spent fuel storage cabin; the bottoms and the side faces of the primary containment and the spent fuel storage cabin are elastically connected with the double-shell ship body through elastic connecting structures; a nuclear fuel loading and unloading cabin is arranged on the upper portions of the primary containment and the spent fuel storage cabin; and communication ports are formed between the nuclear fuel loading and unloading cabin and the primary containment and between the nuclear fuel loading and unloading cabin and the spent fuel storage cabin respectively. The nuclear fuel tank has three functions of containment, nuclear fuel loading and unloading and spent fuel storage, and has the characteristics of regular appearance,compact layout, low design pressure and light shielding weight; and an elastic connecting structure is provided, so that the safety of the reactor cabin is further improved.

Description

technical field

[0001] The invention relates to the field of offshore floating nuclear power plants, in particular to a stack layout structure of a floating nuclear power plant. Background technique

[0002] Floating nuclear power plants use ships as their carrying platforms, and need to set up stacks on ships, so that the layout functions of nuclear islands in land-based nuclear power plants are transplanted to the stacks of floating nuclear power plants. However, due to the different environmental conditions of the sea and the land environment, the space and weight of the ship are limited, there are threats of collision and impact at sea, and the hull is bent and torsional. Structural protection requirements for marine environmental conditions.

[0003] Existing nuclear-powered submarines or ships have two disadvantages: one is that the cabin for independent refueling of the ship is not considered, which increases the construction requirements for the land refueling base;...
