REVIEW RESPONSIBILITIES Primary - Auxiliary Systems Branch (ASB) Plant Systems Branch (SPLB)1 Secondary - None I. AREAS OF REVIEW The reactor coolant pressure boundary (RCPB) leakage detection systems are designed to provide a means of detecting and to the extent practical, identifying the source of the reactor coolant leakage. The ASB SPLB reviews those areas of the SAR relating to the system design 2 to determine its adequacy to perform the detection and monitoring function to assure conformance with the requirements of General Design Criteria 2 and 30. The ASB SPLB3 reviews the system design with respect to the following: 1. The system is capable of identifying to the extent practical, the source of the reactor coolant leakage. 2. The system is capable of separately monitoring and collecting leakage from both identifiable and unidentifiable sources. 3. The system is adequately equipped with indicators and alarms for each leakage detection system in the main control room, and readily permits qualitative interpretations of such indicators. 4. The system provides for the monitoring of systems connected to the RCPB for signs of intersystem leakage. DRAFT Rev. 2 - April 1996 5.2.5-2 Review Interfaces:4 SPLB also reviews the environmental capability of those portions of the system necessary to perform their design safety functions under abnormal, accident, and postaccident environments as part of its primary review responsibility for SRP section 3.11.5 In addition, the ASB SPLB will coordinate other branches' evaluations that interface with the 6 overall review of the system as follows: 1. The Instrumentation and Control Systems Branch (ICSB) Instrumentation and Controls Branch (HICB) and the Power Systems Branch (PSB) determines the adequacy of the 7 design, installation, testing and inspection of electrical components (sensing, and control, power) required for proper operation as part of theirits primary review responsibility for SRP Sections 7.5 and 8.3 respectively
