Content:
ection 3.2.1, “Seismic Classification,” provides guidance to the NRC staff in reviewing seismic classification of SSCs for nuclear power plant applications. o SRP Chapter 7, “Instrumentation and Controls” provides guidance on Regulatory Guide 1.97, and seismic requirements for instrumentation and control portions of systems and components in mild environments. o SRP Section 19.3, “Regulatory Treatment of Non-safety Systems for Passive Advanced Light Water Reactors,” provides guidance to the NRC staff in reviewing the regulatory treatment of non-safety systems for which certain seismic expectations have been established so that they can withstand the SSE. • RG 1.97, “Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants” (Ref. 5), provides guidance for complying with the agency’s regulations with respect to satisfying criteria for accident monitoring instrumentation in nuclear power plants. • RG 1.100, “Seismic Qualification of Electric and Mechanical Equipment for Nuclear Power Plants” (Ref. 6), provides guidance on the qualification of electrical and mechanical equipment to withstand the effects of the SSE and remain functional. DG-1315, Page 3 • Regulatory Guide 1.189, “Fire Protection for Operating Nuclear Power Plants” (Ref. 7), provides guidance used to establish the design requirements for portions of fire protection SSCs to meet the requirements of GDC 2, as they relate to designing those SSCs to withstand the effects of the SSE. • Regulatory Guide 1.205, “Risk-Informed, Performance-Based Fire Protection for Existing Light- Water Nuclear Power Plants” (Ref. 8), provides guidance to comply with 10 CFR 50.48(c) to implement a risk-informed, performance-based fire protection program. Purpose of Regulatory Guides The NRC issues regulatory guides to describe to the public methods that the staff considers acceptable for use in implementing specific parts of the agency’s regulations, to explain techniques
