Layout structure of floating nuclear power plant

Abstract

The invention discloses a floating nuclear power plant reactor cabin layout structure, which comprises a double-hulled hull arranged on an offshore nuclear power platform, the inner cavity of the double-hulled hull is provided with a primary containment vessel and a spent fuel storage compartment, and the primary containment is provided with a There are reactors and primary circuit system equipment, and spent fuel storage facilities are installed in the spent fuel storage tank. The bottom and sides of the primary containment and spent fuel storage tanks are elastically connected to the double-hull hull through elastic connection structures. The primary containment and spent fuel The upper part of the storage cabin is provided with a nuclear fuel loading and unloading cabin, and connecting ports are respectively provided between the nuclear fuel loading and unloading cabin, the primary containment vessel and the spent fuel storage cabin. The invention has three functions of containment, nuclear fuel loading and unloading, and spent fuel storage, and has the characteristics of regular shape, compact layout, low design pressure and light shielding weight; and an elastic connection structure is proposed to further increase the safety of the reactor cabin.

Description

technical field [0001] The invention relates to the field of offshore floating nuclear power plants, in particular to a stack arrangement structure of a floating nuclear power plant. Background technique [0002] The floating nuclear power plant uses the ship as the carrying platform, and it is necessary to set up a stack on the ship, and transplant the layout function of the nuclear island of the land nuclear power plant to the stack of the floating nuclear power plant. 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 ...

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; the other is that the containment and hull structure are integrated, and the hull load The strength transmitted to the containment is relatively high, and the safety is affected
