tems, and supporting data communication systems. Review Methods - Regulatory Guide 1.118 provides a basis for evaluating conformance to GDC 21 and IEEE Std. 279-1971, Clause 4.10. The guidance applies equally to IEEE Std. 603-1991, Clause 5.7. The I&C evaluation is limited to the review of testing of protection systems. The evaluation of testing of electric power systems is addressed by others in the review of Chapter 8 of the SAR. SRP BTP 7-17 discusses periodic test provisions in digital computer-based systems. (i) Regulatory Guide 1.151, “Instrument Sensing Lines” (endorses ANSI/ISA-S67.02-1980, “Nuclear Safety-Related Instrument Sensing Line Piping and Tubing Standard for Use in Nuclear Power Plants”) Applicability - I&C sensing lines and sensing line environmental control systems. Review Methods - Regulatory Guide 1.151 provides a basis for evaluating conformance to GDC 13. Environmental control systems for all I&C systems are addressed in the review of Section 7.7 of the SAR. (j) Regulatory Guide 1.152, “Criteria for Digital Computers in Safety Systems of Nuclear Power Plants” (endorses IEEE Std. 7-4.3.2-2003, “IEEE Standard Criteria for Digital Computers in Safety Systems of Nuclear Power Generating Stations”) Applicability - All I&C safety systems and supporting data communication systems. Review Methods - Regulatory Guide 1.152 provides a basis for evaluating conformance of computers with GDC 21. SRP Appendix 7.1-D provides review guidance for the evaluation of conformance to the guidance of Regulatory Guide 1.152. (k) Regulatory Guide 1.168, “Verification, Validation, Reviews and Audits for Digital Computer Software Used in Safety Systems of Nuclear Power Plants” (endorses IEEE Std. 1012-1998, “IEEE Standard for Software Verification and Validation,” and IEEE Std. 1028-1997, “IEEE Standard for Software Reviews and Audits”) Applicability - All I&C systems and components important to safety. Review Methods - Regulatory Guide 1.168
