Problems solved by technology
In power plants of the same type of technology, the increase in single-unit capacity can certainly achieve better economics, but at the same time it brings huge pressure on nuclear safety, which in turn has a negative impact on the obtained economy and the safety of power grid operation. Negative effects have come. It can be said that the economic effect of the capacity scale of a single nuclear power unit has reached its limit.

Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings of the description.
[0020] Such as figure 1 Shown is the layout structure of the nuclear island powerhouse provided by the present invention. The nuclear island powerhouse includes a plurality of reactor powerhouses, fuel powerhouses and two auxiliary powerhouses; multiple reactor powerhouses are arranged symmetrically on both sides of the fuel powerhouse; Auxiliary buildings are arranged on both sides of multiple reactor buildings; connection buildings are set between multiple reactor buildings and fuel buildings; new and spent fuel receiving facilities and spent fuel temporary storage pools are installed in the fuel buildings, and every two symmetrically arranged reactors The plant shares a refueling channel, and each refueling channel is connected to the spent fuel temporary storage pool.
[0021] In this way, multiple reactor buildings can share new and s...

The invention relates to a nuclear island plant arrangement structure. Nuclear island plants comprise a plurality of reactor plants, a connection plant, a fuel plant and two auxiliary plants. The multiple reactor plants are symmetrically arranged on the two sides of the fuel plant in a rowed mode. The connection plant is arranged between the multiple reactor plants and the fuel plant. The two auxiliary plants are arranged on the two sides of the multiple reactor plants. A new and spent fuel receiving facility and a spent fuel temporary storage pool are arranged in the fuel plant. The multiple reactor plants share the new and spent fuel receiving facility and the spent fuel temporary storage pool. By the adoption of the arrangement structure, the integrity and the economical efficiency of the nuclear island plants are improved, and the construction cost of a nuclear power plant is reduced; external events can be effectively replied, the overall safety of the nuclear power plant is improved, and the acceptance of people to nuclear safety is improved; and arrangement is flexible, the adaptability is high, and the nuclear island plant arrangement structure can adapt to different unit capacities, plant site conditions and construction scales without large adjustment.
Description
technical field [0001] The invention belongs to the field of nuclear island design, and in particular relates to an arrangement structure of a nuclear island powerhouse. Background technique [0002] Under the low-carbon development model, nuclear power is the best choice to solve the contradiction between high energy consumption, high power demand and carbon emission reduction pressure caused by the heavy industrialization of my country's economy. [0003] Economy and safety are important factors affecting investment in nuclear power plants. In order to improve the economics of nuclear power generation, it is mainly to reduce the construction cost by increasing the unit capacity and the scale of the power station. At present, the maximum unit capacity has reached 1650MWe. In power plants of the same type of technology, the increase in single-unit capacity can certainly achieve better economics, but at the same time it brings huge pressure on nuclear safety, which in turn h...
