t removal, reactor coolant inventory, containment isolation, and containment integrity. • For plants with a digital RTS or ESFAS, DAS functions and other D3-related functions are reviewed to confirm that they are consistent with the portions of the accident analysis that support the D3 analysis. The specific acceptance criteria and review procedures are contained in the reference SRP sections. II. 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 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 the 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 diverse actuation systems 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, Appendix A, General Design Criterion (GDC) 1, “Quality Standards and Records.” 7.8-4 Revision 5 - March 2007 4. GDC 13, “Instrumentation and Control.” 5. GDC 19, “Control Room.” 6. GDC 24, “Separation of Protection and Control Systems.” Note that the design of the diverse I&C systems
