for these systems. The application of RG 1.189 to the review of safe shutdown I&C systems should be coordinated with the organization responsible for fire protection. (u) RG 1.200, “An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results for Risk-Informed Activities.” Applicability - All I&C Systems. Review Methods - RG 1.200 provides a basis for the conformance to GDC 13 as part of the evaluation of I&C surveillance test interval changes for purposes other than the accommodation of a 24 month fuel cycle change. RG 1.200 provides guidance on determining that the quality of the PRA, in total or the parts that are used to support an application, is sufficient to provide Appendix 7.1-A-35 Revision 6 – August 2016 confidence in the results such that the PRA can be used in regulatory decision making for light-water reactors. (v) RG 1.204, “Guidelines for Lightning Protection of Nuclear Power Plants” (endorses IEEE Std 665, IEEE Std 666, “IEEE Design Guide for Electrical Power Service Systems for Generating Stations,” IEEE Std 1050, IEEE Std C62.23, “IEEE Application Guide for Surge Protection of Electric Generating Plants,” and applicable portions of referenced secondary standards). Applicability - All I&C systems and components important to safety. Review Methods - RG 1.204 provides a basis for evaluating conformance of I&C systems and components with 10 CFR 50.55a, 10 CFR 50.55a(h), and GDC 2. RG 1.204 provides guidance in the design and installation of lightning protection systems to ensure that electrical transients resulting from lightning phenomena do not render I&C systems important to safety inoperable or cause the spurious operation of such systems. RG 1.204 also endorses the applicable portions of the following standards, which are referenced by IEEE Std 665, IEEE Std 666, IEEE Std 1050, or IEEE Std C62.23. • IEEE Std 80-2000, “IEEE Guide for Safety in AC Substation Grounding” • IEEE Std 81-1983,
