s from nuclear power plants will not exceed specified limits.61 DRAFT Rev. 4 - April 1996 11.5-10 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, ETSBPERB will compare the listing of process and effluent monitors contained in the 62 SAR with the principal release points identified in SRP Section 11.1 to assure ensure that all major process streams and release pathways are being monitored during normal operation, anticipated operational occurrences, and postulated accidents. In addition, PERB will review monitoring of nonradioactive systems that could become radioactive through interfaces with radioactive systems. The review includes the following: 63 a. The location of probes, detectors, sampling points, and 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 N13.1-19691993,64 "Guide to Sampling Airborne Radioactive Materials in Nuclear Facilities." (Ref. 5).65 b. The equipment, piping, and description of sampling methods to assure ensure representative sampling will be compared with the guidelines given in Regulatory Guide 1.21. c. ETSBPERB will independently calculate, on an audit basis, the radiation levels 66 and concentrations in process and effluent streams using the models of NUREG- 0016 or NUREG-0017 to verify the expected levels (Refs. 6 and 7).67 d. ETSBPERB will compare the sampling frequencies, types of analyses required, 68 and monitoring instrument sensitivities and ranges with those recommended in Regulatory Guides 1.21 and 1.97. At the OL or COL stage, ETSBPERB will 69 70 compare the applicant's monitoring
