Integrated modular pressurized water reactor with 69 reactor core

Abstract

The invention belongs to field of integrated modular pressurized water reactor technology, and concretely relates to an integrated modular pressurized water reactor with a 69 reactor core. A voltage-stablizer, multiple modular steam generators, multiple wet winding main pumps, and multiple groups of control rod drive mechanisms are totally and internally arranged in a reactor pressure vessel in order to integrate into an integrated pressurized water reactor module; The voltage-stablizer is also used as a top cover of the reactor pressure vessel, an inverted cap shaped double-layer stainless steel thermal insulation board with a composite structure and air interlayers is internally arranged in the voltage-stablizer, electric heating elements are circumferentially and uniformly and horizontally arranged in the voltage-stablizer, and the electric heating elements are arranged on the thermal insulation board; multiple groups of built-in control rod drive mechanisms are arranged below the thermal insulation board and above the reactor core by using a modular double layer assembling arrangement. The product better solves contradiction of safety and economical efficiency of small reactors with good engineering realizability.

Description

technical field [0001] The invention belongs to the technical field of integrated modular pressurized water reactors, and in particular relates to an integrated modular pressurized water reactor with 69 reactor cores. Background technique [0002] Small heaps have high safety, but always face economic difficulties. In recent years, the U.S. Department of Energy and the International Atomic Energy Agency have proposed a modular design concept for reactors, trying to improve the economics of small and medium-sized reactor applications while obtaining high safety through modular design. However, the size and power ratio of the reactor are relatively large, and the form of containment, the setting of passive system facilities, the refueling process and the combined arrangement of modules are not reasonable, and the engineering feasibility is poor. Contents of the invention [0003] The purpose of the present invention is to provide an integrated modular pressurized water reac...
