REACTOR COOLANT PRESSURE BOUNDARY RCPB

This section discusses the measures employed to provide and maintain the integrity of the Reactor Coolant Pressure Boundary (RCPB) throughout the facility s design lifetime. The RCPB is defined in accordance with ANSI/ANS 51.1-1983. Included are all pressure containing components such as pressure vessels, piping, pumps, and valves which are ... 

An In-service Inspection (ISI) program will be provided for the examination of the Reactor Coolant Pressure Boundary (RCPB) components and supports defined as Code Class 1. The program will reflect the principles and Intent embodied In the ASME Boiler and Pressure Vessel Code, Section XI. Specific Code Editions and addenda required by 10 CFR 50.55(a) are referenced In the Pressure Inspection (PSI) and ISI programs. The purpose of the In-service Inspection program Is to periodically monitor the systems or components requiring In-service Inspection in order to identify and to repair those indications which do not meet acceptance standards. 

REACTOR COOLANT PRESSURE BOUNDARY (RCPB) LEAKAGE DETECTION SYSTEMS... 

The acceptance criteria for the resolution of GSI 029 are that proven bolting designs, materials, and fabrication techniques shall be employed. In addition, reactor coolant pressure boundary (RCPB) bolting shall meet the requirements of ASME Code, Section III (Reference 2). Also, for RCPB bolting the owner-operator shall use established industry practice in developing maintenance, assembly, and disassembly procedures. Furthermore for RCPB and its support bolting, inservice inspection shall meet the requirements of ASME, Section XI (Reference 2),... 

The acceptance criteria for the resolution of GSI 119.5 for the design of a future plant are that the Reactor Coolant Pressure Boundary (RCPB) leakage detection systems shall meet the requirements and be consistent with the guidance of Regulatory Guide 1.45 (Reference 4).
