erform gross beta-gamma and gross alpha measurements isotopic analyses, and other routine analyses in conformance with Regulatory Guide 1.21. c. Provisions should be made to perform routine instrument calibration, maintenance, and inspections in conformance with guidelines of Regulatory Guide 4.15. The frequencies of such actions should be given in the plant DRAFT Rev. 4 - April 1996 11.5-6 technical specifications RETS, ODCM, and/or PCP. The provisions will be 43 reviewed at the OL or COL stage. Provisions should also be made to replace or 44 decontaminate monitors without opening the process system or losing the capability to isolate the effluent stream. d. Isolation valves, dampers, or diversion valves with automatic control features should fail in the closed or safe position. Setpoints for actuation of automatic control features initiating actuation of isolation valves, dampers, or diversion valves should be established in the plant technical specificationsRETS, ODCM, and/or PCP. Non-ESF instrumentation provisions for automatic termination or 45 diversion of releases should conform to the design guidance contained in Appendix 11.5-A (this SRP section). ESF instrumentation provisions for automatic termination or diversion of releases are reviewed in SRP Section 7.6 by ICSBHICB.46 11.5-7 DRAFT Rev. 4 - April 1996 4. Provisions should be made for the instrumented monitoring or sampling and analysis of identified gaseous effluent paths in the event of postulated accident releases. To meet Criterion GDC 64 as it relates to potential gaseous effluent paths, the design of systems should meet the provisions of NUREG-0718 and NUREG-0737 (Refs. 9 and 10) (Items II.F.1, Attachments 1 and 2), 10 CFR 50.34(f)(2)(vxii) and 10 CFR 47 50.34(f)(2)(vxxii), Appendix 11.5-A (this SRP section) (Ref. 11), and Regulatory 48 49 Guide 1.97 (Position C and Table 1 or Table 2, as applicable) (Ref. 3).50 5. Provisions should be made for the instrumented monitoring or sampling and analysis
