Industry Codes and Standards; Amended Requirements

The U.S. Nuclear Regulatory Commission (NRC) proposes to amend its regulations to incorporate by reference a later edition and addenda of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPV Code) and the ASME Code for Operation and Maintenance of Nuclear Power Plants (OM Code) to provide updated rules for construction, inservice inspection (ISI), and inservice testing (IST) of components in light-water cooled nuclear power plants. The proposed rule identifies the latest edition and addenda of the ASME BPV and OM Codes that have been approved for use by the NRC subject to certain limitations and modifications. The NRC is also withdrawing a supplemental proposed rule that would have eliminated the requirement for licensees to update their ISI and IST programs every 120 months to the latest ASME Code edition and addenda incorporated by reference in the regulations.
