Independent Assessment of Nuclear Material Control and Accounting Systems

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."
