Incorporation by Reference of American Society of Mechanical Engineers Boiler and Pressure Vessel Code Cases

Краткое содержание

The Nuclear Regulatory Commission (NRC) is proposing to amend its regulations to incorporate by reference the latest revisions of two previously incorporated regulatory guides (RGs) that approve Code cases published by the American Society of Mechanical Engineers (ASME). These RGs are 1.84, "Design and Fabrication Code Case Acceptability, ASME Section III," Revision 34 and RG 1.147, "Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1," Revision 15. This proposed action would allow licensees to use the Code Cases listed in the regulatory guides as alternatives to requirements in the ASME BPV Code regarding the construction and inservice inspection of nuclear power plant components.
