Nuclear island plant arrangement structure

Abstract

The invention relates to a nuclear island plant arrangement structure comprising a reactor plant, a nuclear auxiliary plant, an electric plant and a fuel plant. The nuclear auxiliary plant, the electric plant and the fuel plant are arranged around the reactor plant. An operating hall platform of the reactor plant is arranged on a + / -0.00 m elevation layer. The nuclear island plant arrangement structure has the beneficial effects that 1, by building the fuel plant, the nuclear auxiliary plant and the electric plant around the reactor plant, the compact layout can be guaranteed, the occupied area is decreased, and economic performance is achieved; 2, as for nuclear island plant arrangement, by arranging an operating hall on the + / -0.00 m elevation layer, building of auxiliary facilities canbe reduced, the technical process for mounting and transporting of main equipment is simplified, and the mounting, overhauling and maintaining time is shortened; 3, arrangement is conducted accordingto the safety levels of items, and thus safe production of a nuclear island is facilitated; and 4, a shell of the reactor plant is of a double-layer structure, a water tank is arranged on the top layer of the reactor plant, thus, the emergency situation can be effectively defended, and production safety is guaranteed.

Description

technical field [0001] The invention belongs to the field of nuclear engineering, 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. Common nuclear island plant reactor plant and fuel plant operation hall need to add gantry and other facilities when carrying out main equipment transportation and fuel operation, which increases the projec...
