Two-phase natural circulation integrated reactor

Abstract

The invention belongs to the technical field of nuclear reactors, and particularly relates to a two-phase natural circulation integrated reactor which comprises a pressure vessel (1), a hanging basket(3) in the pressure vessel (1), a reactor core (2) located in the bottom of the hanging basket (3), and a heat exchange area (5) located on the periphery of the top of the hanging basket (3) and communicated with a secondary loop, and the space, located above the reactor core (2), in the hanging basket (3) is a primary loop reactor core outlet chamber (7). First steam generated by the reactor core (2) enters the heat exchange area (5) through the primary loop reactor core outlet cavity (7) to heat cooling water provided by the second loop into second steam, then the second steam is convertedinto condensate water and flows back to the reactor core (2), and the second steam is conveyed to the second loop. The reactor and the steam generator are integrated in the pressure vessel 1, equipment is simplified, the design of a main pump, a primary loop pipeline, a pressure stabilizer and the like is canceled, the risks of active equipment faults and crevasse are reduced, and the influence ofradioactive products on secondary loop equipment is avoided.

Description

technical field [0001] The invention belongs to the technical field of nuclear reactors, in particular to a two-phase natural circulation integrated reactor. Background technique [0002] In a nuclear reactor system, there are generally a primary loop system and a secondary loop system. After the cooling water of the primary loop of the nuclear reactor is heated through the core, the heat is transferred to the water of the secondary loop, and the water of the secondary loop forms steam to drive the turbo generator. Such a design often requires a series of supporting equipment such as main pumps, primary circuit piping, pressurizers, and steam generators outside the reactor for heat exchange between the primary and secondary circuits, making the entire reactor system too complex. [0003] Since the 21st century, small reactors have attracted the attention of countries all over the world due to the advantages of low initial investment, short construction period, low requiremen...
