Detailed Description

The nuclear reactor fuse comprises: the neutron absorption device comprises a bracket, a neutron absorption rod, a neutron reflection tile and an alloy hoop; the neutron reflection tile is tightly hooped and fixed by a plurality of alloy hoops, so that the neutron reflection tile does not fall off, the alloy hoops are formed by mixing a plurality of metals with lower melting points, and the melting points are close to and lower than the limit working temperature of the reactor; the nuclear reactor fuse tube is arranged near a nuclear fuel rod in a nuclear reactor, and the normal operation of the nuclear reactor cannot be influenced because the neutron absorption rod is completely surrounded by the neutron reflection tile and is not exposed; when the reactor is out of control due to various accidental reasons and the temperature of the reactor core continuously rises to be close to the ultimate working temperature of the reactor, the alloy hoop of the reactor protecting tube is melted, the neutron reflecting tile loses the fixation of the alloy hoop, the whole neutron reflecting tile falls into the bottom of the pool, the neutron absorbing rod is completely exposed to absorb neutrons of the nuclear fuel rod, so that the reactor is stopped, the reactor stops working, and the safety is ensured; the safety tube of the nuclear reactor is the last safety guarantee of the nuclear reactor and can effectively protect the operation safety of the nuclear reactor.
