Approval of American Society of Mechanical Engineers' Code Cases

The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment three draft regulatory guides (DG), DG-1230, "Design, Fabrication and Materials Code Case Acceptability, ASME Section III"; DG-1231, "Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1"; and DG-1232, "Operation and Maintenance code Case, Acceptability, ASME OM Code." The subject DGs list the Code Cases that the NRC has approved for use by applicants and licensees. Code Cases provide an acceptable voluntary alternative to the mandatory American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (BPV) Code and Operation and Maintenance (OM) of nuclear power plant provisions approved by the NRC.
