igned the system efficiencies for removal of elemental iodine and organic iodides given in Tables 2 and 1 of Regulatory Guide 1.52 revisions 2 and 3 respectively and a system efficiency of 1Regulatory Guides 1.3, 1.4, and RG 1.25 provide guidance related to Technical Information Document (TID) 14844, “Calculation of Distance Factors for Power and Test Reactor Sites.” This guidance is applicable to a holder of an operating license issued prior to January 10, 1997 or a holder of a renewed license under 10 CFR Part 54 whose initial operating license was issued prior to January 10, 1997. These license holders may voluntarily revise the accident source term. Regulatory Guide1.183 is applicable to applicants or license holders issued after January 10, 1997. 6.5.1-8 Revision 3 - March 2007 99% for removal of particulates resulting from a DBA. The assigned efficiencies are for the organization responsible for the review of design basis accident radiological consequence analyses use in accident analyses to calculate offsite doses to the whole body and thyroid. B. The system has provisions to prefilter air, remove moisture, and meet the guidance of Regulatory Guide 1.52 for charcoal adsorption. C. The system is redundant, is designed to Seismic Category I requirements, is able to actuate automatically, and is limited to an airflow rate of approximately 15 m3/s (30,000 cfm). D. Design of instrumentation for ESF atmosphere cleanup systems conforms to the guidelines of Regulatory Guide 1.52 and to the recommendations of ASME N509-1989. Instrumentation, readout, recording, and alarm provisions for ESF atmosphere cleanup systems meet the minimum guidance given in Table 6.5.1-1 of this SRP section. E. Environmental design guidelines for acceptability are based on the conditions following a DBA. Radiation source terms are consistent with the guidelines in Regulatory Guides 1.3, 1.4, 1.1831, 1.7, and 1.25. F. Fabrication of the charcoal tray and screen involves all-welded
