components are compared to the acceptance criteria in determining the appropriate safety classification. In addition, RG 1.206, Part I, C.I.3, Sections 3.2.1 and 3.2.2, and SRP Section 3.8.4, identify applicable acceptance criteria in evaluating SSCs requiring seismic design considerations and discuss differences from the recommendations of RG 1.143. 7. The review will compare the design, testing, and maintenance criteria for HEPA filters and charcoal absorbers in filtration systems against the provisions of RG 1.140. 8. If a potential for explosive hydrogen and oxygen mixtures exists, it will be determined, using the system description and P&IDs, whether the applicant has designed the GRS to withstand the effects of such an explosion or has provided dual instrumentation and design features to annunciate and prevent the buildup of potentially explosive mixtures. The applicant’s design is reviewed to ensure that it includes adequate provisions to stop continuous leakage paths after an explosion. The areas of concern are: (a) process streams where water decomposition gases (hydrogen and oxygen) exist, (b) cover gas streams where air in-leakage can occur, and (c) areas where there is a possibility of liquid hydrocarbons and ozone collecting in a cryogenic distillation system. 9. The SREC, ODCM, and TS Administrative Controls, Section 5.5, , proposed by the applicant for process and effluent controls will be evaluated as part of the review identified in SRP Section 11.5, and SRP Chapter 16, as adopted from standard technical specifications (NUREG-1430, NUREG-1431, NUREG-1432, NUREG-1433, and NUREG-1434). The reviewer will determine whether the content of the SREC and ODCM, calculation methods, and scope of the programs identified in the Administrative Controls section of the TS are in agreement with the requirements identified as a result of the staff’s review. The review will include the evaluation or development of appropriate controls and the limiting conditions
