Description

The risk analysis principles, guidance, and implementation strategies presented in this Standard are broadly applicable; however, this Standard has been specifically developed for applications involving fixed pressure-containing equipment and components. This Standard is not intended to be used for nuclear power plant components; see ASME BPV, Section XI, Rules for Inservice Inspection of Nuclear Power Plant Components. It provides guidance to owners, operators, and designers of pressure-containing equipment for developing and implementing an inspection program. These guidelines include means for assessing an inspection program and its plan. The approach emphasizes safe and reliable operation through cost-effective inspection. A spectrum of complimentary risk analysis approaches (qualitative through fully quantitative) should be considered as part of the inspection planning process.
