Setpoints for Safety-Related Instrumentation
The U.S. Nuclear Regulatory Commission (NRC) is issuing draft regulatory guide (DG), DG-1141, ``Setpoints for Safety-Related Instruments'' for public comment. This DG is proposed Revision 4 of Regulatory Guide (RG) 1.105, ``Setpoints for Safety-Related Instrumentation.'' This DG describes proposed updates to the recommended practices and criteria for determining instrument setpoints and appropriate setpoint related criteria. This DG describes proposed practices and criteria that the staff of the NRC considers acceptable for demonstrating compliance with NRC requirements for ensuring that setpoints for safety related instruments are initially within, and should remain within, technical specification limits. This DG also proposes practices and criteria for establishing those technical specification limits and ensuring that those limits will adequately support the proper operation of the associated systems.
