Reactor and reactor vessel thereof

Abstract

The invention discloses a reactor and a reactor vessel thereof. The reactor vessel (100) comprises a protection vessel (110), a main vessel (120), at least one separator (140) and a plurality of sodium detection devices, wherein the protection vessel (110) defines an accommodating space; the main vessel (120) is arranged in the accommodating space, a gap (130) is formed between the main vessel (120) and the protection vessel (110), and the main vessel (120) is used for accommodating a reactor core and forming a flowing space of liquid sodium for cooling the reactor core; the at least one separator (140) is used for separating the gap (130) into a plurality of spacer regions (141); and each of the spacer regions (141) is provided with at least one of the sodium detection devices, and each of the sodium detection devices arranged in the spacer regions (141) is used for detecting the liquid sodium in the corresponding spacer regions (141). According to the reactor and the reactor vessel thereof, the leakage area can be conveniently defined while the leakage of the main vessel is detected, so that the safety of the reactor is ensured.

Description

technical field [0001] The present application relates to the technical field of reactors, in particular to a reactor and its container. Background technique [0002] A reactor, also known as an atomic energy reactor or a nuclear reactor, is a device that can maintain a controllable self-sustaining chain nuclear fission reaction to realize the utilization of nuclear energy. The reactor can use liquid sodium to cool the core. However, the liquid sodium may flow out from the main container containing the core. In order to ensure the safety of the reactor, it is necessary to monitor whether there is liquid sodium leakage in the reactor. However, related technologies cannot effectively identify Areas where liquid sodium spills occur. Contents of the invention [0003] In one aspect, the present application provides a reactor container, including: a protective container defining an accommodating space; a main container disposed in the accommodating space, a gap is formed betwe...
