re required for the safety systems to accomplish their safety functions, should meet the applicable specifications for Class 1E equipment and circuits. Applicability - Information systems important to safety and supporting data communications systems in ALWRs. For nuclear power plants with construction permits issued before January 1, 1971, the display and control features should be consistent with their licensing basis or may meet the standards of IEEE Std 603-1991 (including the correction sheet dated January 30, 1995). For nuclear power plants with construction permits issued after January 1, 1971, but before May 13, 1999, the display and control features should meet the standards of IEEE Std 279-1971 or IEEE Std 603-1991 (including the correction sheet dated January 30, 1995). For nuclear power plants with construction permits issued after May 13, 1999, the display and control features should meet the standards of IEEE Std 603-1991 (including the correction sheet dated January 30, 1995). In addition, these features should conform, as appropriate, to RGs that support and amplify the guidance of IEEE Std 279-1971 and IEEE Std 603-1991. Review Methods - Section 7.5 describes methods for review of annunciator systems in ALWRs. Appendix 7.1-A-28 Revision 6 – August 2016 4. RGs (including endorsed industry codes and standards) (a) RG 1.22, “Periodic Testing of Protection System Actuation Functions” Applicability - RTS, ESFAS, diverse I&C systems, and supporting data communications systems. Review Methods - RG 1.22 provides bases for evaluating conformance to GDC 21 and IEEE Std 279-1971, Clauses 4.10 through 4.13. The guidance applies equally to IEEE Std 603-1991, Clauses 5.7, 5.8.3, 6.5, 6.7, 7.5, and 8.3. SRP BTP 7-8 describes the staff position on the scope of periodic testing in protection systems. SRP BTP 7-17, “Guidance on Self-Test and Surveillance Test Provisions,” provides additional guidance on acceptable periodic testing provisions for digital
