rne Radioactive Materials in Nuclear Facilities" (Ref. 5). b. The equipment, piping, and description of sampling methods to assure representative sampling will be compared with the guidelines given in Regulatory Guide 1.21. 11.5-5 Rev. 3 - July 1981 c. ETSB will independently calculate, on an audit basis, the radiation levels and concentrations in process and effluent streams using the models of NUREG-0016 or NUREG-0017 to verify the expected levels (Refs. 6 and 7). d. ETSB will compare the sampling frequencies, types of analyses required, and monitoring instrument sensitivities and ranges with those recom- mended in Regulatory Guides 1.21 and 1.97. At the OL stage, ETSB will compare the applicant's monitoring instrumentation specifications and performance criteria with those contained in ANSI N13.10-1974 (Ref. 8) and in Appendix 11.5-A (this SRP section). e. In the review of the P&IDs for the liquid and gaseous waste treatment systems, ETSB will verify that release points for radioactive material have provisions for automatic termination of releases in the event they exceed a predetermined level. Instrumentation provisions for automatic termination of releases will be compared with the design guidance contained in Appendix 11.5-A (this SRP section). f. ETSB will review.the location of the monitors shown on the P&IDs and the location of readouts, annunicators, and alarms discussed in SAR Chapter 7 to assure that the operator will be advised of system per- formance and effluent releases consistent with the release limits specified in the plant technical specifications. g. ETSB will compare the proposed calibration methods and frequency of calibration with the guidelines in Regulatory Guide 1.21 (FSAR) and Regulatory Guide 4.15. h. ETSB will assure that provisions are included in the design for replac- ing or decontaminating detectors without opening the-boundary of the process system or without losing the capability to isolate the system or divert the effluent to a
