Nuclear Regulatory Commission October 26, 2016 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) is issuing Revision 1 to Regulatory Guide (RG) 5.51, ``Independent Assessment of Nuclear Material Control and Accounting Systems.'' Revision 1 is based on experience gained since RG 5.51 was initially published in June 1975, and reflects revisions to the NRC's material control & accounting (MC&A) regulations that have been made since 1975. Updates include use of the term ``independent assessment'' to replace ``management review,'' and use of the term ``inventory difference'' to replace ``material unaccounted for.''
