formation provided in the SAR pertaining to the design of the communication system and related plant features will be evaluated to determine that intra-plant communication equipment 16 needed in vital areas during recovery actions from transient, fire or accident conditions is provided in a manner compatible with the proper operation of other plant equipment . Material 17 will be selected and emphasized from this SRP section as may be deemed appropriate for a particular case. A. The design basis, design criteria, system description sections, and the analyses that 18 demonstrate the effectiveness of the system when maximum plant noise levels are being generated during incident and accident conditions are reviewed to verify that the communication system will function effectively. Engineering judgment is used in conjunction with a comparison of the system capabilities with equipment and communication systems provided for previously approved plants. The PSBHICB will 19 accept the communication system if a statement in the SAR commits the applicant to perform a functional test under conditions that simulate the maximum plant noise levels being generated during the various operating conditions, including fire and accident conditions , to demonstrate system capabilities. 20 B. The reviews which follow are conducted for new applications considering the applicant's analysis of specific communications needs, including the security communications requirements, upon which the design is based.21 9.5.2-3 DRAFT Rev. 3 - April 1996 1. The reviewer verifies that effective communication will not be impeded by problems of transmission through thick concrete walls, high-noise areas, personnel use of protective equipment, too few communication lines/channels, or interference with or from other electronic or electrical equipment.22 2. The reviewer verifies the adequacy of any plant features needed to alert personnel in high noise environments to use the communications systems as well as
