tures 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 regulatory guides 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. 4. Regulatory Guides (including endorsed industry codes and standards) (a) Regulatory Guide 1.22, “Periodic Testing of Protection System Actuation Functions” Applicability - RTS, ESFAS, diverse I&C systems, and supporting data communication systems. Review Methods - Regulatory Guide 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 provides additional guidance on acceptable periodic testing provisions for digital computer-based systems. (b) Regulatory Guide 1.47, “Bypassed and Inoperable Status Indication for Nuclear Power Plant Safety Systems” Appendix 7.1-A-26 Revision 5 - March 2007 Applicability - RTS, ESFAS, information systems important to safety, safety interlock systems, and supporting data communication systems. Review Methods - Regulatory Guide 1.47 provides bases for evaluating conformance to GDC 21 and IEEE Std. 279-1971, Clauses 4.13 and 4.20, for protection systems. The guidance applies equally to IEEE Std. 603-1991, Clauses 5.8.2 and 5.8.3. The regulatory guide also provides bases for evaluating the adequacy of bypass and inoperable status indication for I&C systems important to safety as
