mendations of ERDA 76-21 and ASME N509-1989. 1RGs 1.3, 1.4, and 1.25 provide guidance related to Technical Information Document (TID) 14844, ACalculation of Distance Factors for Power and Test Reactor Sites.@ This guidance is applicable to a holder of an OL issued prior to January 10, 1997 or a holder of a renewed license under 10 CFR Part 54 whose initial OL was issued prior to January 10, 1997. These license holders may voluntarily revise the accident source term. RG 1.183 is applicable to applicants or license holders issued after January 10, 1997. 6.5.1-9 Revision 4 - May 2010 H. Inplace testing includes meeting the requirements of ASME N510-1989. For laboratory testing of activated carbon adsorbent, conformance with ASME N509-1989 will be used as an acceptability criterion. I. For the post-LOCA ESF atmosphere cleanup system, the organization responsible for the review of ventilation and air filtration will accept the following deviations from the above criteria: i. If the calculated dose (sum of the long-term doses from the LOCA and the purge dose at the low population zone outer boundary) is less than the criteria of 10 CFR 100.11 or 10 CFR 100.21, as applicable, no filtration system is needed. ii. If a radioiodine decontamination factor of 10 or less is needed for the calculated dose to be below 10 CFR 100.11 or 10 CFR 100.21, as applicable, an atmosphere cleanup system that meets the design, testing, and maintenance guidelines for HEPA filters and charcoal adsorbers as specified in RG 1.140 are acceptable. If decontamination factors for iodine differ from those specified in RG 1.140 for design purposes, this fact should be supported by test data under operating or simulated conditions (including temperature, pressure, humidity, expected iodine concentrations, and flow rate). The effects of aging and poisoning by airborne contaminants should also be supported by test data. iii. If a radioiodine decontamination factor of greater than 10 is needed for the
