適用范圍：This standard applies to in-core (on-line) neutron detectors and instrumentation which is designed for safety, information or control purposes. It also applies to components in so far as these compo-nents are contained within the primary envelope of the reactor. The detector types usually used are d.c. ionization chambers, fission ion chambers and self-powered neutron detectors.This standard is intended as a code of practice for the design of in-core instrumentation for neutron fluence r?te measurements in thermal neutron reactors designed for power production.The major emphasis in this guide is on the general design aspect of on-line systems.Nole. — For the principles of overall system design and purpose of neutron flux measurements, reference should be made to IEC Publication 231, General Principles of Nuclear Reactor Instrumentation, Clause 2.
