Reactor, reactor main equipment and waterproof ring for reactor main equipment

Abstract

The invention relates to a reactor, reactor main equipment and a waterproof ring for the reactor main equipment. The reactor main equipment comprises a cylinder body, reactor internals are arranged inthe cylinder body, and the circumferential rings of the reactor internals and the inner wall of the cylinder body are arranged at intervals. A pipe connecting port is arranged on the side wall of thecylinder body, and an outlet channel and an inlet channel which are isolated from each other are formed in the pipe connecting port. The waterproof ring comprises a ring-shaped body and an extendingpart extends outwards the edge of the ring-shaped body; and an outer ring of the ring-shaped body corresponds to the shape of the inner wall surface of the cylinder body, the outline dimension of an inner ring of the ring-shaped body is more than that of the outer ring of the reactor components, and the reactor components and the inner ring of the waterproof ring are sealed after the reactor components are expanded, so that a plurality of independent of ring cavities are formed in the reactor of the main equipment, a loop coolant forms a circulating loop according to the design intention of asmall reactor, the coolant can move in the mutually independent channels in the main equipment, a long main pipeline structure is omitted, and compact arrangement of nuclear island main equipment is realized.

Description

technical field [0001] The invention relates to the field of nuclear power, and more specifically relates to a reactor, main equipment of the reactor and a water barrier used for the main equipment of the reactor. Background technique [0002] Small reactors, especially offshore small reactors, require a compact arrangement between the main equipment of the nuclear island in order to meet the harsh environmental requirements. [0003] In the related art, the main equipment of the primary circuit is usually connected between the main equipment through pipelines to realize the circulation of the coolant among the main equipment. The way of pipeline connection makes the reactor occupy a large space. It is not conducive to the miniaturization of the reactor. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a reactor, reactor main equipment and a water barrier used for the reactor main equipment. [0005] The technic...
