anage- ment systems being designed to control release of radioactive materials to the environment. C. General Design Criteria 63 and 64 as they relate to the radioactive waste management systems being designed to monitor radiation levels and leakage. Specific criteria necessary to meet the relevant requirements of the Commission regulations identified above are: 1. Provisions should be made for the instrumented monitoring or for the sampling and analyses of all normal and potential effluent pathways for release of radioactive materials to the environment to meet General Design Criterion 64. 11.5-2 Rev. 3 - July 1981 To meet Criterion 64, the design of systems should meet the provisions of Regulatory Guide 1.21 (Position C and Appendix A) (Ref. 2), Regulatory Guide 1.97 (Position C and Table 1 or Table 2, as applicable) (Ref. 3), and Regulatory Guide 4.15 (Position C) (Ref. 4). a. The gaseous and liquid process streams or effluent release points should be monitored and sampled according to Tables 1 and 2. b. For both BWRs and PWRs, liquid wastes and confined volumes of gaseous waste should be sampled batchwise prior to release, in accordance with Regulatory Guide 1.21. Continuous gaseous effluent monitors are not required for open structures, such as PWR turbine buildings or atmospheric vents for liquid waste tanks containing treated or processed liquid waste and located outside of buildings. For liquid and gaseous effluents that cannot be practicably monitored or sampled batchwise, one of the following methods of representative sampling should be provided: (1) A continuous proportioning sampling system with at least two sample collection tanks. The system should be designed to pro- vide a fixed or measured flow ratio of the sample collected to the sampled stream discharge, or, alternatively (2) A periodic automatic grab sampling system with at least two sample collection tanks. The system should be designed to collect a fixed volume of sample at a rate proportional
