rborne contamina- tion are made in conjunction with the assigned meteorologist. A secondary review Is performed by the Effluent Treatment Systems Branch (ETSB) and the Siting Analysis Branch (SAB) and the results are used by AEB in its overall evaluation of the control room habitability. ETSB reviews the iodine removal efficiencies of the control room atmosphere filtration system. The efficiencies are transmitted to AEB for use in the analysis and are referenced in the SER. The evaluation of the potential hazardous gas sources is performed by the SAB under SRP Section 2.2. The SAB will provide AEB with a description of the sources. In those cases where the identified sources are found to have the potential for incapacitating people in the vicinity of the control room building, the SAB will provide AEB with source location, estimated hazardous gas concentrations near the control room building, and probability for the releases with respect to transportation accidents. In addition, AEB will coordinate the evaluation with other branches that interface with the review of the control room habibility system as follows: the Auxiliary System Branch (ASB) reviews the design of the control room ventilation system as part of its primary review responsibility for SRP Section 9.4.1. The Radiological Assessment Branch (RAB) reviews radiation shielding and exposures as part of the primary review responsibility for SRP Sections 12.1 through 12.5. The review for technical specifications are coordinated and performed by the Licensing Guidance Branch (LGB) as part of the primary review responsibility for SRP Section 16.0. The acceptance criteria necessary for the review and their application are contained in the above referenced SRP section. of the corresponding primary branch. 1I. ACCEPTANCE CRITERIA The control room habitability system design is acceptable if the requirements of the following regulations are met: a.
