tem II.F.1 and Attachments 1 and 2; 10 CFR 50.34(f)(2)(viii); 10 CFR 50.34(f)(2)(xiv)(E); 10 CFR 50.34(f)(2)(xvii); 10 CFR 50.34(f)(2)(xxvi); and 10 CFR 50.34(f)(2)(xxvii), Appendix 11.5-A to this SRP section, and RG 1.97. SRP Chapter 7 and BTP 7-10 provide additional guidance on the application of RG 1.97. For any portion of the PERMISS (accident monitoring systems) that supports safety-related functions, the review addresses the performance, design, qualification, display, QA, and selection of monitoring variables of radiation monitoring equipment required for accident monitoring and sampling. In addition, the design of the 11.5-20 Revision 6 – January 2016 gaseous waste collection and processing system should meet the guidance of SRP Sections 9.3.2, 11.3, and 13.3, as well as the following conditions: A. Administrative controls and procedures should be consistent with Acceptance Criterion 3 (above) of this SRP section in minimizing inadvertent or accidental releases of radioactive gaseous and particulate effluents. B. Gaseous and particulate radiological effluent monitors should be provided for the automatic termination of releases in the event that effluent release setpoints are exceeded, as described in Acceptance Criterion 1 (above) of this SRP section, and implemented in the plant’s RETS/SREC and ODCM. C. When two or more radiation monitoring systems are used for accident monitoring on a single discharge point, differences in instrumentation response characteristics should be described over their overlapping operational ranges for expected concentrations of noble gases, particulates, and halogens. 5. Provisions should be made for monitoring instrumentation, sampling, and sample analysis for all identified liquid effluent release paths in the event of a postulated accident. These provisions should be in accordance with GDC 64 and the requirements of 10 CFR 50.34(f)(2)(viii), 10 CFR 50.34(f)(2)(xiv)(E), 10 CFR 50.34(f)(2)(xvii), 10 CFR 50.34(f)(2)(xxvi),
