Continuous measurement system for reactor core neutron flux entering from bottom of pressure vessel

The invention belongs to the technical field of reactors, and particularly relates to a reactor core neutron flux continuous measurement system for entering from the bottom of a pressure vessel. The device comprises 50 finger sleeves, and the 50 finger sleeves are installed in a reactor core guide pipe and are fastened and sealed with the guide pipe. The system further comprises 50 self-powered neutron detector complexes, and the 50 self-powered neutron detector complexes are introduced. And each self-powered neutron detector complex is provided with a plurality of self-powered detectors and a plurality of thermocouple detectors for temperature measurement. And after the 50 self-powered neutron detector complexes are mounted at the specified coordinates and height positions of the reactor core, the 50 self-powered neutron detector complexes are combined with an inlet of the finger sleeve and are sealed and fastened. The system further comprises a signal acquisition processing cabinet matched with the self-pow
