lication of Regulatory Guide 1.189 to review of safe shutdown I&C systems should be coordinated with the organization responsible for fire protection. (u) Regulatory Guide 1.200 (For Trial Use), “An Approach for Determining the Technical Accuracy of Probabilistic Risk Assessment Results for Risk-Informed Activities.” Applicability - All I&C Systems. Review Methods - Regulatory Guide 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. Regulatory Guide 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 confidence in the results such that the PRA can be used in regulatory decision making for light-water reactors. (v) Regulatory Guide 1.204, “Guidelines for Lightning Protection of Nuclear Power Plants” (endorses IEEE Std. 665-1995, “IEEE Guide for Generating Station Grounding,” IEEE Std. 666-1991, “IEEE Design Guide for Electrical Power Service Systems for Generating Stations,” IEEE Std. 1050-1996, “IEEE Guide for Instrumentation and Control Equipment Grounding in Generating Stations," IEEE Std. C62.23-1995, “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 - Regulatory Guide 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. Regulatory Guide 1.204 provides guidance in the design and installation of lightning protection systems to assure that electrical transients resulting from lightning phenomena do not render I&C systems important to safety inoperable or cause spurious operation of such systems. Regulatory Guide 1.204 also endorses the applicable portions of
