ions 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 construction to preclude potential loss of charcoal from adsorber cells. Further guidance on charcoal loss is found in NRC Bulletin 80-03. G. Components such as demisters, heaters, prefilters, HEPA filters, mounting frames, filter housings, adsorbent, fans, ductwork, and dampers are designed, constructed, and tested in accordance with ASME N509-1989 design and qualification testing criteria. Water drain design and the accessibility of components and ease of maintenance are in accordance with the recommendations of ERDA 76-21 and ASME N509-1989. 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 6.5.1-9 Revision 3 - March 2007 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 Regulatory Guide 1.140 are acceptable. If decontamination factors for iodine differ from those specified in Regulatory Guide 1.140 for design purposes, this fact should be supported by test data under operating or simulated conditions (including temperature, pressure, humidity, expected
