potential noise levels. III. REVIEW PROCEDURES The information provided in the SAR pertaining to the design of the communica- tion system will be evaluated to determine that intra-plant communication equip- ment needed in vital areas during recovery actions from transient, fire or acci- dent conditions is provided. Material will be selected and emphasized from this SRP section as may be deemed appropriate for a particular case. The design basis, design criteria, system description sections, and the analyses that 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 PSB will 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 condi- tions, including fire and accident condition, to demonstrate system capabilities. IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and that the his review supports conclusions of the following type, to be included in the staff's safety evaluation report: The communication system includes all components for intra-plant and plant-to-offsite communications. The scope of review of the communi- cations system for the _ plant included verification that offsite equipment is capable of providing for notification of person- nel and implementation of evacuation procedures, and verification that onsite communications are adequate in the event of an emergency. The basis for acceptance of the communication system in our review was conformance of the design, design criteria, and design bases to staff positions and
