aths in the event of a postulated accident. To meet Criterion 64, as it relates to postulated accidents and identified liquid effluent paths, the design of plant liquid waste collection and processing streams should meet the guide- lines referenced in SRP Sections 9.3.3 and 11.2 and, in addition, the following conditions should be met: a. Administrative controls and procedures in conformance with subsection II.3 of this SRP section are to be in effect to minimize inadvertent or accidental releases of radioactive liquids, and b. Liquid effluent radiological monitors are to be provided for the automatic termination of releases in the event that effluent setpoints, as provided in subsection II.1 of this SRP section, and as established in the plant technical specifications, are exceeded. III. REVIEW PROCEDURES The reviewer will select and emphasize material from this SRP section as may be appropriate for a particular case. 1. In the review of the process and effluent radiological monitoring and sampling system, ETSB will compare the listing of process and effluent monitors contained in the SAR with the principal release points identified in SRP Section 11.1 to assure that all major process stress and release pathways are being monitored during normal operation, anticipated operational occurrences, and postulated accidents. The review includes the following: a. The location bf probes, detectors, sampling points, 4nd.sample stations, and the bases for the selection of these sampling or monitoring. points are compared with the general principles for obtaining valid samples of airborne radioactive materials, the methods and materials for gaseous and particulate sampling, and guides for sampling from ducts and stacks contained in ANSI N13.1-1969, Guide to Sampling Airborne Radioactive Materials in Nuclear Facilities" (Ref. 5). b. The equipment, piping, and description of sampling methods to assure representative sampling will be compared with the guidelines given in
