ments, depending on design features. The guidance of RG 1.143 applies to the balance of the GWMS since it is not a safety-related system. 11.3-8 Draft Revision 4 – August 2014 18. For any portion of the GWMS post-accident systems that supports safety-related functions, as identified by the applicant, the review of these design features is performed using the guidance in SRP Chapter 7 and SRP Section 13.3, “Emergency Planning.” In this context, the review, using the guidance in RG 1.97, “Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants,” addresses the performance, design, qualification, display, quality assurance, and selection of monitoring variables for radiation monitoring equipment required for accident monitoring and sampling. 19. With respect to the operation of the GWMS and associated releases of gaseous effluents to unrestricted areas regulated under 10 CFR Part 20, the review of instrumentation and components, with respect to capability, reliability, and conformance to the acceptable criteria is performed using the guidance in SRP Sections 7.1, “Instrumentation and Controls – Introduction,” 7.5, “Information Systems Important to Safety,” 7.6, “Interlock Systems Important to Safety,” and 7.7, ” Control Systems,” and related branch technical positions in SRP Chapter 7, as mandated by design and operational considerations. 20. Review of design features of building exhaust and ventilation systems servicing radiologically controlled areas where GWMS equipment and radioactive materials are located and used to vent tanks and process equipment (e.g., use of HEPA and charcoal filters) is conducted using the guidance in SRP Section 9.4 and, for instrumentation used to monitor and control radioactive effluent releases, SRP Section 11.5. SRP Section 11.5 provides guidance on the review of instrumentation used to monitor and control (terminate and/or divert) gaseous radioactive effluent releases and process streams
