Application Summary AI generated
This standard specifies the technical requirements, test methods, and inspection rules for direct current (D.C.) periodmeters used in nuclear instrumentation. It is applied in the design, manufacturing, and quality verification of instruments that measure the reactor period (rate of change of neutron flux) in nuclear reactor control and safety systems. The standard ensures reliable performance of these meters in monitoring reactor startup and power transients within nuclear power plants and research reactors.
