ACCEPTANCE CRITERIA Requirements Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 1. 10 CFR 50.55a(a)(1), “Quality Standards.” 2. 10 CFR 50.55a(h), “Protection Systems and Safety Systems,” requires compliance with IEEE Std 603-1991, “IEEE Standard Criteria for Safety Systems for Nuclear Power Generating Stations,” and the correction sheet dated January 30, 1995. For nuclear power plants with construction permits issued before January 1, 1971, the applicant/licensee may elect to comply instead with their plant-specific licensing basis. For nuclear power plants with construction permits issued between January 1, 1971, and May 13, 1999, the applicant/licensee may elect to comply instead with the requirements stated in IEEE Std 279-1971, “Criteria for Protection Systems for Nuclear Power Generating Stations.” For safe shutdown systems that are not safety systems as 7.4-4 Revision 5 - March 2007 defined by IEEE Std 603-1991 and that are isolated from safety systems, the applicable requirements of 10 CFR 50.55a(h) are IEEE Std 279-1971 Clause 4.7, “Control and Protection System Interaction” IEEE Std 603-1991 Clause 5.6.3, “Independence Between Safety Systems and Other Systems;” and IEEE Std 603-1991, Clause 6.3, “Interaction Between the Sense and Command Features and Other Systems.” 3. 10 CFR 50.34(f)(2)(xx), “Power for Pressurizer Level Indication and Controls for Pressurizer Relief and Block Valves,” or equivalent TMI action plan requirements imposed by Generic Letters. 4. 10 CFR 50, Appendix A, GDC 1, “Quality Standards and Records.” 5. GDC 2, “Design Bases for Protection against Natural Phenomena.” 6. GDC 4, “Environmental and Missile Design Bases.” 7. GDC 13, “Instrumentation and Control.” 8. GDC 19, “Control Room.” 9. GDC 24, “Separation of Protection and Control Systems.” 10. GDC 34, “Residual Heat Removal.” 11. GDC 35, “Emergency Core
