ered as malfunctions of an automatic safety system. Such an occurrence could challenge the integrity of the reactor core, reactor coolant pressure boundary, containment, and associated systems. 10 CFR 50.36(c)(3), “Technical Specifications,” states that surveillance requirements are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met. 2. Relevant Guidance Regulatory Guide 1.105, Revision 3, “Setpoints for Safety-Related Instrumentation,” provides guidance for ensuring that instrument setpoints are initially - and remain - within the technical specification limits. This regulatory guide endorses ISA-S67.04-1994, Part I, “Setpoints for Nuclear Safety-Related Instrumentation Used in Nuclear Power Plants.” ISA-S67.04-1994, Part II, “Methodology for the Determination of Setpoints for Nuclear Safety-Related Instrumentation,” provides additional guidance, but Regulatory Guide 1.105, Revision 3, does not endorse or address Part II of ISA-S67.04-1994. NRC Regulatory Issue Summary (RIS) 2006-17, “NRC Staff Position on the Requirements of 10 CFR 50.36, ‘Technical Specifications,' Regarding Limiting Safety System Settings During Periodic Testing and Calibration of Instrument Channels,” discusses issues that could occur during testing of LSSS. BTP 7-12-3 Revision 5 - March 2007 IEEE Std. 498-1990, "IEEE Standard Requirements for the Calibration and Control of Measuring and Test Equipment Used in Nuclear Facilities," and ANSI/NCSL Std. Z540-1-1994, "Calibration Laboratories and Measuring and Test Equipment - General Requirements," provide guidance for the calibration and control of measuring and test equipment used in the maintenance of instrument setpoints.
