alyses, and other routine analyses in conformance with Regulatory Guide 1.21. c. Provisions should be made to perform routine instrument calibra- tion, maintenance, and inspections in conformance with guidelines of Regulatory Guide 4.15. The frequencies of such actions should be given in the plant technical specifications. The provisions will be reviewed at the OL stage. Provisions should also be made to replace or 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 specifications. Non-ESF instrumentation Provisions for automatic termination or diversion of releases should conform to the design guidance contained in 11.5-4 Rev. 3 - July 1981 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 ICSB. 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 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), Appendix 11.5-A (this SRP section) (Ref. 11), and Regulatory Guide 1.97 (Position&C, and Table I or Table 2, as applicable) (Ref. 3). 5. Provisions should be made for the instrumented monitoring or sampling and analysis of identified liquid effluent paths in the event of a postulated accident. To meet Criterion 64, as it relates to postulated accidents and identified liquid effluent paths, the design of plant liquid waste collection and processing
