1971, the applicant’s 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/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 Part 50, “Domestic Licensing of Production and Utilization Facilities,” Appendix A, “General Design Criteria for Nuclear Power Plants,” General Design Criterion (GDC) 1, “Quality Standards and Records.” 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 must be such that the protection system continues to meet the requirements of 10 CFR Part 50, Appendix A, Section III, “Protection and Reactivity Control Systems.” Review of the reactor protection system for these areas of conformance is addressed in SRP Sections 7.2 and 7.3. Additional requirements applicable to any information system important to safety proposed for standard DC or COLs under 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants.” 7. 10 CFR 52.47(b)(1), which requires that a DC application contain the proposed ITAAC that are necessary and sufficient to provide reasonable assurance that, if the inspections, tests, and analyses are performed and the acceptance criteria met, a plant that incorporates the design certification is built and will
