This standard specifies the principles, characteris ics, requirements and test methods related to neutron fluence rate instrumentation and measurement based on the mean square voltage method in nuclear power plant reactor control. This standard is applicable to instruments and measurement channels that obtain information related to the neutron fluence rate of nuclear power plant reactors by calculating the mean square voltage value of the neutron detector signal. Other nuclear facilities can refer to it for use.
