ication and Use of Valves in Power Plant Systems”, NP-5479, “Application Guidelines for Check Valves in Nuclear Power Plants,” NP-5697, “Valve Stem Packing Improvements,” NP- 6737, “Cobalt Reduction Guidelines,” and NP-6316, Guidelines for Threaded-Fastener Application in Nuclear Power Plants,” that provided contemporary operating experience regarding design practices beneficial to reducing ORE. While the state of technology has advanced since the issuance of the initial URD, the reports referenced within the URD, revised versions of those reports and new reports (e.g. “Pressurized Water Reactor Primary Water Zinc Application Guidelines,”) related to improving equipment reliability are sources of information that describe the current state of technology that may be used to evaluate design specifications provided to ensure ORE is ALARA through the use of reliable and low maintenance valves, pumps and other components, consistent with the guidance in RG 8.8 and the requirements of 10 CFR 20.1003 and 1101(b), and 12.3-12.4-25 Draft Revision 5 – October 2012 10 CFR 52.47(a)(22) to ensure that operating insights have been incorporated into the plant design. The reviewer will consider plant layout and intended access and egress traffic patterns both to determine conformance with 10 CFR 20.1601, 10 CFR 20.1602, 10 CFR 20.1901, 10 CFR 20.1902, 10 CFR 20.1903, 10 CFR 20.1904, 10 CFR 20.1905, or Standard Technical Specifications and to determine whether they will control access properly in limited and restricted access areas (high radiation and very high radiation areas). The staff will review SAR Chapters 5, 9 and 11 as necessary to evaluate dose rates in and around the spent fuel pool areas, the location of airborne radioactivity monitoring instruments within ventilation systems, and radwaste systems as they relate to radiation protection design. The reviewer will evaluate all relevant aspects of the initial design plans, particularly to identify new
