ide on Surge Testing for Equipment Connected to Low-Voltage AC Power Circuits”) Applicability - All I&C systems and components important to safety. Review Methods - Regulatory Guide 1.180 provides a basis for evaluating conformance of I&C systems and components with 10 CFR 50.55a(a)(1), 10 CFR 50.55a(h), GDC 1, GDC 2, GDC 4 and Criteria III and XI. Regulatory Guide 1.180 identifies electromagnetic environment operating envelopes, design, installation, and test practices acceptable to the staff for addressing the effects of electromagnetic interference/radio frequency interference (EMI/RFI), and power surges on I&C systems and components important to safety. Regulatory Guide 1.180 also endorses the applicable portions of the following standards, which are referenced by IEEE Std. 1050-1996. • IEEE Std. 518-1982, “IEEE Guide for the Installation of Electrical Equipment to Minimize Noise Inputs to Controllers from External Sources” • IEEE 665-1995, “IEEE Guide for Generating Station Grounding” (t) Regulatory Guide 1.189, “Fire Protection for Operating Nuclear Power Plants” Appendix 7.1-A-32 Revision 5 - March 2007 Applicability - Safe shutdown I&C systems. Review Methods - Regulatory Guide 1.189 compiles fire protection regulations and guidelines into a comprehensive guide. It provides a basis for evaluating conformance of I&C systems and components with 10 CFR Part 50 Appendix A GDC 19, GDC 25, and 10 CFR 50 Appendix R. Regulatory Position 5 of the Regulatory Guide provides performance goals for safe shutdown, alternate and dedicated shutdown systems. This position also identifies systems and instrumentation generally necessary for achieving hot shutdown and cold shutdown and provides guidance on design criteria and analysis methods for these systems. Application of Regulatory Guide 1.189 to review of safe shutdown I&C systems should be coordinated with the organization responsible for fire protection.
