hould be protected using appropriate measures, such as check valves, backflow preventers, interlocks, differential pressures, etc. Contaminated purged fluids should be returned to the most appropriate RWMS for processing. 3. Provisions should be made for administrative and procedural controls for the installation of auxiliary or ancillary equipment, inclusions of special features in instrumentation and radiological monitoring sampling systems, and for the analysis of process and effluent streams. In complying with GDC 63 and GDC 64 requirements (including the requirements specified in 10 CFR 50.34(f)(2)), as they relate to radioactive waste process systems and effluent discharge paths, the design of systems and the implementation of administrative and procedural controls should be consistent with the guidance of Appendix 11.5-A to this SRP section, RG 1.21 (Position C), RG 4.15 (Position C), and Appendix A to RG 1.33. SRP Chapter 7 and BTP 7-10 provide additional guidance on the application of RG 1.97 for any portion of the PERMISS (accident monitoring systems) that supports safety-related functions, as identified by the applicant. The full provisions of 10 CFR 50.34(f)(2) include 10 CFR 50.34(f)(2)(viii), 10 CFR 50.34(f)(2)(xiv)(E), 10 CFR 50.34(f)(2)(xvii), 10 CFR 50.34(f)(2)(xxvi), and 10 CFR 50.34(f)(2)(xxvii)). Instrumentation, sampling, and monitoring provisions should conform to the following: A. Sampling frequencies, required analyses, instrument alarm/trip setpoints, calibration and sensitivities, and provisions for preparing composite samples for radioactivity analyses should implement the guidance of RGs 1.21, RG 1.33, and RG 4.15. The plant’s RETS/SREC and ODCM should indicate sampling frequencies and required analyses. B. Provisions should be made for the necessary instrumentation and facilities to perform gross beta-gamma and gross alpha measurements, isotopic or radionuclide-specific analyses, and other routine analyses using the guidance of RG
