Content:
irculating at a rate of not less than two tank volumes in 8 hours. For gaseous and liquid process stream samples, provisions should be made for purging sampling lines and for reducing the plate-out of radioactive materials in sample lines. Provisions for gaseous sampling from ducts and stacks should be consistent with ANSI/HPS N13.1- 1999. B. When 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 with SRP Section 9.3.2 and 10 CFR 20.1406. 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 controls for the installation of necessary auxiliary or ancillary equipment, for the inclusion of special features in instrumentation and radiological monitoring sampling systems, and for the analysis of process and effluent streams. For GDC 63 and 64 (including the requirements specified in 10 CFR 50.34(f)(2)(xvii) and 10 CFR 50.34(f)(2)(xxvii)), 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 meet the guidelines of Appendix 11.5-A, RG 1.21 (Position C), RG 4.15 (Position C), and Appendix A to RG 1.33. Instrumentation, sampling, and monitoring provisions should conform to the following: 11.5-11 Revision 5 - May 2010 A. Sampling frequencies, required analyses, instrument alarm/trip setpoints, calibration and sensitivities, and provisions for preparing composite samples for low-level radioactivity analyses should conform to RGs 1.21, 1.33, and 4.15. The plant’s SREC, ODCM, and/or PCP 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
