The self-powered detectors are widely used in the third generation nuclear power plants. Combining with the requirements of the standards IEC 61468 and EJ/T78, the structure of self-powered neutron detector is introduced, and the measuring principle and compensation principle for self-powered neutron detector are analyzed in accordance with the standard of IEC 61648. In addition, the calculation method for the current signal, the γ-ray compensation and background compensation of Cobalt self-powered detector are introduced in detail and researched. These provide technical support for selecting reactor core neutron flux detectors in subsequent new projects.
