This standard specifies the design principles and requirements for nuclear reactor neutron flux rate measuring core instruments. This standard applies to on-line neutron detectors and core neutron flux measurement components and instruments designed for reactor safety-important purposes (protection, information or control). Commonly used detectors are DC ionization chambers, fission ionization chambers, and self-powered neutron detectors.
