ls, the acceptance criterion of RG 1.143 is 1 mSv (100 mrem) for members of the public assumed to be located at or beyond the restricted area or in unrestricted areas (whichever is most limiting). For unmitigated radiation exposures to site personnel, the acceptance criterion is 5 rem (50 mSv) for a plant worker assumed to be located in the restricted area. In classifying system components, the radioactivity inventories of 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 11.3-26 Draft Revision 4 – August 2014 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
