mples, provisions should be made for purging sample lines and for reducing plateout in sample lines. Provisions for gaseous sampling from ducts and stacks should be in agreement with ANSI N13.1. (Ref. 5) b. Where practicable, provisions should be made to collect samples from process waste streams at central sample stations to reduce leakage, spillage and radiation exposures to operating personnel in accordance wit; SRP Section 9.3.2. c. Provisions should be made to purge and drain sample streams back to the system of origin or to an appropriate waste treatment system. 3. Provisions should be made for administrative and procedural control for necessary auxiliary or ancillary equipment, and for special features for the instrumented radiological monitoring, sampling, and analysis of process and effluent streams. To meet Criterion 63 and Criterion 64, as they relate to radioactive waste process systems and effluent discharge paths, the design of systems and the implementation of adminis- trative and procedural controls should meet the guidelines of Appendix 11.5-A (this SRP section), Regulatory Guide 1.21 (Position C) and Regula- tory Guide 4.15 (Position C). 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 low-level analyses should be in conformance with Regulatory Guides 1.21 and 4.15. Sampling frequencies and required analyses should be given in the plant technical specifications; these provisions will be reviewed at the OL stage. b. Provisions should be made for the necessary instrumentation and facilities to perform 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 calibra- tion, maintenance, and inspections in conformance with
