eters or associated functional requirements on a parameter-by-parameter basis. The evaluation of instrumentation for monitoring environs conditions and radiation monitoring systems is addressed in the review of other sections of the SAR. SRP Section 7.5 and BTP 7-10 describe the review of accident monitoring instrumentation. (g) Regulatory Guide 1.105, “Setpoints for Safety-Related Instrumentation” (endorses Part 1 of ISA-S67.04-1994, “Setpoints for Nuclear Safety-Related Instrumentation”) Applicability - All I&C systems. Review Methods - Regulatory Guide 1.105 provides a basis for evaluating conformance to GDC 13 and IEEE Std. 279-1971, Clause 3. The guidance applies equally to IEEE Std. 603-1991, Clause 6.8. SRP BTP 7-12 provides guidance for establishing and maintaining instrument setpoints. Regulatory Guide 1.105 and ISA-S67.04-1994 provide guidance for establishing setpoints for trip functions. Nevertheless, their guidance is equally relevant to accounting for measurement uncertainties when determining the indicated plant conditions at which emergency procedures will require operator action, determining the setpoint for interlock functions, and determining setpoints for control functions provided to maintain plant variables and systems within prescribed operating ranges. Therefore, the guidance of Regulatory Guide 1.105 is useful in reviewing all I&C systems important to safety even if no automatic trip functions are involved. (h) Regulatory Guide 1.118, “Periodic Testing of Electric Power and Protection Systems” (endorses IEEE Std. 338-1987, “Standard Criteria for the Periodic Surveillance Testing of Nuclear Power Generating Station Safety Systems”) Appendix 7.1-A-28 Revision 5 - March 2007 Applicability - All I&C safety systems, diverse I&C systems, 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
