assurance that offsite doses of radiation resulting from accident conditions will not exceed regulatory limits and that releases will be adequately documented. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant=s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 1. The organization responsible for the review of ventilation and air filtration reviews the plant design to determine where ESF atmosphere cleanup systems are needed. This effort is coordinated with the organization responsible for the review of design basis accident radiological consequence analyses. 2. The organization responsible for the review of ventilation and air filtration review is carried out by making a detailed comparison of atmosphere cleanup system designs with the acceptance criteria of Section II, above. 3. The organization responsible for the review of ventilation and air filtration verifies each ESF atmosphere cleanup system, as follows: 6.5.1-8 Revision 4 - May 2010 A. The system is designed so that it can operate after a design-basis accident (DBA) and can retain radioactive material after a DBA. The capability of a system to remove fission products from the atmosphere after a DBA is reviewed, based on a design loading of 2.5 mg of total iodine (radioactive plus stable) per gram of activated charcoal adsorbent. Designs consistent with GDCs 19, 41, 42, 43, 61, and 64 and the guidelines of RG 1.52 will be assigned the system efficiencies for removal of elemental iodine and organic iodides given in Tables 2 and 1 of RG 1.52 revisions 2 and 3 respectively and a system efficiency of 99% for removal of particulates resulting from a DBA. The assigned
