Integrated modular pressurized water reactor with 89 reactor core and suspension main pump

Abstract

The invention belongs to field of integrated modular pressurized water reactor technology, and concretely relates to an integrated modular pressurized water reactor with an 89 reactor core and a suspension main pump. 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 by using a modular double layer assembling arrangement; reactor internals are arranged outside the control rod drive mechanisms, and in the reactor pressure vessel and below the thermal insulation board. 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, in particular to an integrated modular pressurized water reactor with 89 cores suspended from a main pump. 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 wat...
