Nuclear Regulatory Commission June 2, 2009 – Federal Register Recent Federal Regulation Documents

The NRC is proposing to amend its regulations to incorporate by reference the latest revisions of two regulatory guides (RG) that would approve new and revised code cases published by the American Society of Mechanical Engineers (ASME). These are RG 1.84, ``Design, Fabrication, and Materials Code Case Acceptability, ASME Section III,'' Revision 35, and RG 1.147, ``Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1,'' Revision 16. This action would allow the use of the code cases listed in these RGs as alternatives to requirements in the ASME Boiler and Pressure Vessel (BPV) Code regarding the construction and inservice inspection (ISI) of nuclear power plant components. Concurrent with this action, the NRC is publishing a notice of the issuance and availability of the RGs in the Federal Register.

The U.S. Nuclear Regulatory Commission (NRC) is amending its spent fuel storage regulations by revising the Holtec International HI- STORM 100 dry cask storage system listing within the ``List of Approved Spent Fuel Storage Casks'' to include Amendment No. 6 to Certificate of Compliance (CoC) Number 1014. Amendment No. 6 will modify the CoC to add instrument tube tie rods used for pressurized water reactor 15x15 and 17x17 fuel lattices, for both intact and damaged fuel assemblies, to the approved contents of the MPC-24, MPC-24E, MPC-24EF, MPC-32, and MPC-32F models; and to correct legacy editorial issues in Appendices A and B Technical Specifications.
