The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its regulations to incorporate by reference the 2004 Edition of Section III, Division 1 and Section XI, Division 1 of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPV Code) and the 2004 Edition of the ASME Code for Operation and Maintenance of Nuclear Power Plants (OM Code) to provide updated rules for constructing and inspecting components and testing pumps, valves, and dynamic restraints (snubbers) in light-water nuclear power plants. NRC also proposes to require the use of ASME Code Cases N-722 and N- 729-1, both with conditions, and to remove certain obsolete requirements specified in Sec. 50.55a. This action is in accordance with the NRC's policy to periodically update the regulations to incorporate new editions and addenda of the ASME Codes by reference and is intended to maintain the safety of nuclear reactors and make NRC activities more effective and efficient.
