Content:
ctions 3.2.1, 3.2.2, 3.3.1, 3.3.2, 3.5.3, 3.7.1 through 3.7.4, 3.8.4, and 3.8.5 will be used to evaluate exceptions. 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 (1) process streams where water decomposition gases (hydrogen and oxygen) exist in a BWR, (2) cover gas streams where air in-leakage can occur in a PWR, and (3) areas where there is a possibility of liquid hydrocarbons and ozone collecting in a cryogenic distillation system. 4. The GRS design, system layout, equipment design, method of operation, and provisions to reduce leakage and to facilitate operations and maintenance are compared to Regulatory Guide 1.143 for gaseous wastes produced during normal operation and anticipated operational occurrences. Special design features provided to control leakage from system components and topical reports on system designs will be evaluated on a case-by-case basis. 11.3-15 Revision 3 - March 2007 5. The review will compare the design, testing, and maintenance criteria for HEPA filters and charcoal adsorbers in filtration systems against the provisions of Regulatory Guide 1.140. 6. If a potential for explosive hydrogen and oxygen mixtures exist, 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 the required dual instrumentation and design features to annunciate and prevent the buildup of potentially explosive mixtures, respectively. 7. Part of the review identified in SRP Sections 11.5 and 16.0 will evaluate the SREC, ODCM, and Administrative Controls section of the TS proposed by the applicant for process and effluent controls. The reviewer will determine that 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
