mpling system, with at least two sample collection tanks. The system should be designed to collect a sample at a fixed ratio established between the sample collection flow rate and the effluent stream discharge flow rate. ii. Use of a periodic automatic grab sampling system, with at least two sample collection tanks. The system should be designed to collect a sample at a fixed volume established at a rate that is proportional to the effluent stream discharge flow rate. iii. For radioactive materials, other than noble gases in gaseous effluents, a continuous sampling system should be used with replaceable particulate filters and radioiodine adsorbers. The system should be designed to automatically take representative samples at a known flow rate established in accordance with American National Standards Institute/Health Physics Society (ANSI/HPS) N13.1-1999. iv. For intermittently operating effluent release points, the system should be designed to automatically take samples whenever flow is in the effluent stream using a known ratio between the discharge and sampling stream flow rates. v. Periodic sampling and analysis frequencies and types of radiological analyses should be specified for all samples described above in the SREC, ODCM, and/or PCP. 2. Provisions should be made for the installation of instrumentation and monitoring equipment and/or periodic or continuous sampling and analysis of radioactive waste process systems. For GDC 60 and 63, as they relate to radioactive waste systems, detection of excessive radiation levels, and initiation of appropriate safety actions, the design of systems should meet the guidelines of Appendix 11.5-A, Regulatory Guide 1.21 (Position C, as applicable), Regulatory Guide 1.97 (Position C and Table 1 or 2, as applicable), Regulatory Guide 4.15 (Position C), and Appendix A to Regulatory Guide 1.33. SRP BTP 7-10 (see SRP Section 7.5) provides additional guidance on the application of Regulatory Guide 1.97. A. Provisions should be
