and post-accident sampling systems include piping, valves, heat exchangers, and other components associated with the systems 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 design of these systems. The review has included descriptive information for the process and post-accident sampling systems 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 and post-accident sampling systems to applicable regulations, guides, and industry standards. The staff concludes that the design of the process and post-accident sampling systems are acceptable and that the process sampling system meets the relevant requirements of 10 CFR Part 20, § 20.1(c)20.1101(b) and General Design Criteria 1, 2, 13, 14, 26, 41 (for PWR only), 60, 66 63, and 64 in Appendix A to 10 CFR Part 50 , and the post-accident sampling system meets the 67 9.3.2-15 DRAFT Rev. 3 - April 1996 relevant requirements of General Design Criteria 1, 2, 13, 14, and 60 in Appendix A to 10 CFR Part 50 , 10 CFR 50.34(f)(2)(viii), Item II.B.3 of NUREG-0737, 10 CFR 50.34(f)(2)(xxvi), 68 69 and Item III.D.1.1 of NUREG-0737. This conclusion is based on the following: 70 For PWR The staff has determined that the proposed process sampling system meets (1) the requirements of GDC 13 in Appendix A to 10 CFR Part 50 to monitor variables that 71 can affect the fission process for normal operation, anticipated operational occurrences, and accident conditions, by sampling the reactor coolant, the ECCS core flooding tank, the refueling water storage tank, the boric acid mix tank, and the boron injection tank for boron concentrations; (2) the requirements of GDC 13 and 14 in
