Chapter 28, authored by Richard W. Swayne, discusses the Section XI rules for in-service inspection and testing of nuclear power plant components. This chapter covers the general requirements of Section XI applicable to all Classes of components, including concrete structures and steel vessels, piping, pumps, and valves. It identifies the limits of applicability of Section XI, that is, what is within and outside the scope of the Code. Interfaces with applicable regulatory requirements are addressed, and the use of Code Editions, Addenda, and Cases is explained.

Mr. Swayne comments on the periodic NDE and pressure testing to ensure the integrity of components, other than containment vessels, within the scope of jurisdiction of this Code. These requirements include NDE, from personnel qualification to conduct of the NDE. They also include the type and frequency of NDE required, including sample expansion and increased frequency required because of defect detection. Mr. Swayne also addresses periodic pressure testing and pressure testing following R/R activities. Responsibilities and quality assurance program requirements of the different entities involved in examination and testing of a nuclear power plant are discussed.

This chapter addresses many controversial issues and topics of current concern, including the applicability of recent U.S. Nuclear Regulatory Commission (NRC) Generic Letters and Information Notices, and describes ways in which readers can use recent revisions of Section XI to their advantage. References to ASME Interpretations are included to explain how the Code requirements can be applied to common problems. This Edition contains new information from Mr. Swayne on risk-informed in-service inspection and reliability integrity management programs for high-temperature gas-cooled reactors.
