The U.S. Nuclear Regulatory Commission (NRC) is amending its regulations to make technical corrections, including adding three inadvertently omitted addenda to Section XI, "Rules for Inservice Inspection of Nuclear Reactor Coolant Systems," of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV) Code to the list of documents approved for incorporation by reference; and correcting a footnote number. This final rule is necessary to inform the public of these non-substantive changes to the NRC's regulations.
