ic 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.” The minimum requirements that are applicable to all DCS are IEEE Std. 603-1991, Clause 5.6.3, “Independence Between Safety Systems and Other Systems,” or IEEE Std. 279-1971, Clause 4.7.2, “Isolation Devices,” or the plant-specific licensing basis, as defined by 10 CFR 50.55a(h), as noted above. 3. 10 CFR Part 50, Appendix A, General Design Criteria (GDC) 1, “Quality Standards and Records.” 4. GDC 24, “Separation of Protection and Control Systems.” Additional requirements applicable to all DCSs that support protection system functions reactor trip system (RTS) (SRP Section 7.2) or engineered safety features actuation system (ESFAS) (SRP Section 7.3) 1. 10 CFR 50.34(f)(2)(v), regarding automatic indication of bypassed and inoperable status of safety system equipment. For Part 50 applicants not listed in 10 CFR 50.34(f), the provisions of 50.34(f) will be made a requirement during its licensing review. 2. 10 CFR 50.55a(h)(2), “Protection Systems.” 3.
