Nuclear Regulatory Commission May 16, 2013 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) is issuing Revision 2 to Regulatory Guide (RG) 1.57, ``Design Limits and Loading Combinations for Metal Primary Reactor Containment System Components,'' in which there are no substantive changes to the RG. The revision includes correction of a subsection title and editorial changes to improve clarity. This guide describes a method that the NRC staff considers acceptable for design limits and loading combinations for metal primary reactor containment system components.

The U.S. Nuclear Regulatory Commission (NRC), in consultation with the U.S. Department of Transportation (DOT), is proposing to amend its regulations for the packaging and transportation of radioactive material. These amendments would make NRC regulations conform to revisions to the International Atomic Energy Agency (IAEA) regulations for the international transportation of radioactive material and maintain consistency with DOT regulations. These changes are necessary to maintain a consistent regulatory framework for the transportation and packaging of radioactive material. These changes would make the regulation of quality assurance programs more efficient by allowing changes that do not change quality assurance approval holder commitments to be made without prior NRC approval, and extending the duration of quality assurance program approvals. These changes would clarify the responsibilities of general licensees and further limit the shipping of fissile material under a general license. The parallel DOT proposed rulemaking was published in the Federal Register on August 12, 2011.
