A layout structure of a multi-reactor nuclear power plant

Abstract

The invention relates to a multi-reactor nuclear power plant arrangement structure. The nuclear power plant includes a nuclear island and a conventional island. The nuclear island includes a plurality of reactors disposed on the outer layer and a plurality of spent fuel storage tanks disposed on the inner layer, the plurality of reactors and the plurality of spent fuel storage tanks are arranged in a circular structure, the center part enclosed by the spent fuel storage tanks is provided with a fuel transfer platform, the fuel transfer platform is communicated with each reactor through the respective refuelling channel of each spent fuel storage tank, each refuelling channel is provided with a spent fuel transfer port, each spent fuel transfer port is communicated with the corresponding spent fuel storage tank, the conventional island includes a steam turbine plant which is located in the periphery of the nuclear island, and the reactors of the nuclear island share a steam turbine plant. The nuclear power plant of the invention is flexible, compact, and reasonable in arrangement, occupies less area, and is adaptable to the ground, underground, semi-buried or fully buried construction modes of the nuclear island plant, thereby improving the integrity and safety of the nuclear power plant and realizing the scale effect of a nuclear power unit.

Description

technical field [0001] The invention belongs to the field of nuclear power plant design, and in particular relates to an arrangement structure of a multi-stack nuclear power plant. Background technique [0002] In the process of nuclear power technology development, traditional technical means rely on increasing the unit capacity of nuclear power units and the scale of power plants to reduce construction costs. However, in power stations with the same type of technology, the increase in the capacity of a single unit can certainly improve the economy, but the nuclear safety assurance capability is further weakened, which in turn has a negative effect on the obtained economy and the safety of power grid operation. It can be said that the economic effect of the capacity scale of a single nuclear power unit has reached its limit. The nuclear power plants designed according to the traditional technology route are single or double reactors. The scale of such nuclear power units i...

Problems solved by technology

However, in power stations with the same type of technology, the increase in the capacity of a single unit can certainly improve the economy, but the nuclear safety assurance capability is further weakened, which in turn has a negative effect on the obtained economy and the safety of power grid operation. It can be said that the economic effect of the capacity scale of a single nuclear power unit has reached its limit

The nuclear power plants designed according to the traditional technical route are single or double reactors, and the scale of such nuclear power units is relatively low, which cannot give full play to the advanced modular design and construction capabilities
