methodology, and on experience gained from U.S. Nuclear Regulatory Commission (NRC) inspections of operating plants. 1. Regulatory Basis Title 10 of the Code of Federal Regulations (10 CFR) 50.55a(h), “Protection and Safety Systems,” requires compliance with Institute of Electrical and Electronics Engineers (IEEE) Standard(Std) 603-1991, “IEEE Standard Criteria for Safety Systems for Nuclear Power Generating Stations,” and the correction sheet dated January 30, 1995.For nuclear plants with construction permits issued before January 1, 1971, the applicant or licensee may elect to comply instead with the plant-specific licensing basis. For nuclear power plants with construction permits issued between January 1, 1971, and May 13, 1999, the applicant or licensee may elect to comply with the requirements stated in IEEE Std 279-1971, “Criteria for Protection Systems for Nuclear Power Generating Stations.” Clause 4.4 of IEEE Std 603-1991 requires identification of the analytical limit associated with each variable. Clause 6.8.1 requires that allowances for uncertainties between the analytical limit and the device setpoint be determined using a documented methodology. Clause 3(6) of IEEE Std 279-1971 requires identification of the levels that, when reached, will necessitate protective action. 10 CFR Part 50, “Domestic Licensing of Production and Utilization Facilities,” Appendix B, “Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants,” Criterion XI, “Test Control,” and Criterion XII, “Control of Measuring and Test Equipment,” provide requirements for tests and test equipment used in maintaining instrument setpoints. 10 CFR Part 50, Appendix A, “General Design Criteria for Nuclear Power Plants,” General Design Criterion (GDC) 13, “Instrumentation and Control,” requires, in part, that instrumentation be provided to monitor variables and systems and that controls be provided to maintain these variables and
