Solution type nuclear reactor control system

Abstract

The invention discloses a solution type nuclear reactor control system. The system is provided with a feed liquid storage tank out of a graphite reflecting layer of a reactor container, with a size 1 / 10-1 / 15 that of the reactor container. The reactor container is communicated with the bottom of the feed liquid storage tank; a pipeline communicated with corresponding air cavity is drawn forth from the upper potion of the reactor container and the upper portion of the feed liquid storage tank respectively; an air pump pipeline, an automatic regulating valve pipeline, a compensating valve and a safety valve are connected in parallel on the two pipelines, wherein the air pump pipeline exhausts air from the air cavity at the upper portion of the reactor container and presses into the air cavity at the upper portion of the feed liquid storage tank; when the air pressure in the reactor container is lower than that of the feed liquid storage tank, the liquid level in the reactor container rises, and startup of the reactor is realized; and oppositely, as the liquid level in the reactor container descends, power of the reactor decreases, when the air pressure in the reactor container is equal to that of the upper portion of the feed liquid storage tank, shutdown of the reactor is realized, thereby realizing the control of the reactor. The solution type nuclear reactor control system has the advantages of simplified reactor core structure, improved reactivity of the reactor and reduced construction cost of the control system.

Description

technical field [0001] The invention belongs to a nuclear reactor control system, in particular to a solution type nuclear reactor control system. Background technique [0002] The existing solution type nuclear reactor using solution nuclear fuel has a control system consisting of safety rods, compensation rods and automatic adjustment rod systems. The pile container has several vertical conduits, the fuel solution is outside the conduits, and the water in the conduits communicates with the pile pool. The control rod absorber moves up and down in the duct. Since the conduit is the boundary between the fuel solution and the pool water, if there is a leak in the conduit, the fuel solution will mix with the pool water of the stack reflector, causing serious pollution of the pool water and making post-treatment very difficult; The reactivity loss of the stack is very large; the size of the control rod drive mechanism is large and the layout is difficult; and the price of the ...
