al report). For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff’s safety evaluation report. The reviewer also states the bases for those conclusions. The process sampling system includes piping, valves, heat exchangers, and other components from the point of sample withdrawal from a fluid system up to the analyzing station, sampling station, or local sampling point. Our review included the provisions proposed to sample all principal fluid process streams associated with plant operation and the applicant’s proposed PSS design. The review has included descriptive information for the process sampling system and the location of sampling points, as shown on piping and instrumentation diagrams. The basis for acceptance in our review has been conformance of the applicant’s design for the process sampling system to applicable regulations, guides, and industry standards. The staff concludes that the design of the process sampling system is acceptable and that the process sampling system meets the relevant requirements of 10 CFR 20.1101(b) and GDC 1, 2, 13, 14, 26, 41 (for PWR only), 60, 63, and 64. The following paragraphs discuss the bases for this conclusion for each of the requirements, as applicable to PWRs, BWRs, or both. For some designs, which may not contain the listed systems or locations for sampling, sampling of systems or locations found to be equivalent is acceptable in meeting the requirements of this SRP section. For PWR The staff has determined that the proposed process sampling system meets (1) the requirements of GDC 13 to monitor variables that can affect the fission process for normal operation,
