Description

technical field [0001] The invention belongs to the technical field of excore cores, and in particular relates to a detector fixing device and a fixing method. Background technique [0002] The nuclear instrumentation system outside the reactor is a safety-level device. It continuously monitors the reactor power, power level change and power distribution by measuring the neutron flux rate leaked from the reactor core. It is an important input parameter for the reactor protection system and the five major control systems of the power plant. . Therefore, the installation and replacement of nuclear detectors is a very critical process in nuclear power plants. The traditional installation method is to hoist the entire detector from top to bottom. Although this installation method is convenient, it reduces the installation reliability and service life of the detector. The new nuclear power plant adopts the installation method of installing detectors from the bottom of the reac...
