iteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. 1. Provisions should be made for the installation of instrumentation and monitoring equipment and/or sampling and analyses of all normal and potential effluent pathways for release of radioactive materials to the environment, including nonradioactive systems that could become radioactive through interfaces with radioactive systems. For GDC 64 and the requirements specified in 10 CFR 50.34(f)(2)(xvii) and 10 CFR 50.34(f)(2)(xxvii), the system designs should meet the provisions of Regulatory Guide 1.21 (Position C and Appendix A), 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 Branch Technical Position (BTP) 7-10 (see SRP Section 7.5) provides additional guidance on the application of Regulatory Guide 1.97. A. The gaseous and liquid process streams or effluent release points should be monitored and sampled according to Tables 1 and 2 of this SRP. B. For both boiling water-reactors (BWRs) and pressurized-water reactors (PWRs), liquid waste and gaseous waste (contained in tanks) should be sampled on a batch basis before their release, in accordance with Regulatory Guide 1.21. 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, do not require continuous gaseous effluent monitors. For liquid and gaseous effluents that cannot be easily monitored or sampled on a batch basis, one of the following representative sampling methods should be provided: 11.5-7 Revision 4 - March 2007 i. Use of a continuous proportioning sampling 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
