2015-23290. Independent Assessment of Nuclear Material Control and Accounting Systems

AGENCY:

Nuclear Regulatory Commission.

ACTION:

Draft regulatory guide; request for comment.

SUMMARY:

The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment draft regulatory guide (DG), DG-5049, “Independent Assessment of Nuclear Material Control and Accounting Systems.” This DG provides guidance from experience gained since the regulatory guide was initially published in June 1975. In particular, the guidance for performing independent assessments has been expanded to include process monitoring and item monitoring for Category I fuel cycle facilities, and to include guidance for uranium enrichment facilities. In addition, this revision addresses changes in Material Control & Accounting (MC&A) terminology; for example, the term “management review” has been replaced by “independent assessment,” and “material unaccounted for” by “inventory difference.”

DATES:

Submit comments by November 16, 2015. Comments received after this date will be considered if it is practical to do so, but the NRC is able to ensure consideration only for comments received on or before this date. Although a time limit is given, comments and suggestions in connection with items for inclusion in guides currently being developed or improvements in all published guides are encouraged at any time.

The NRC does not routinely edit comment submissions to remove identifying or contact information.

If you are requesting or aggregating comments from other persons for submission to the NRC, then you should inform those persons not to include identifying or contact information that they do not want to be publicly disclosed in their comment submission. Your request should state that the NRC does not routinely edit comment submissions to remove such information before making the comment submissions available to the public or entering the comment submissions into ADAMS.

II. Additional Information

The NRC is issuing for public comment a DG in the NRC's “Regulatory Guide” series. This series was developed to describe and make available to the public information regarding methods that are acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques that the staff uses in evaluating specific issues or postulated events, and data that the staff needs in its review of applications for permits and licenses.

The DG entitled “Independent Assessment of Nuclear Material Control and Accounting Systems” is a proposed revision temporarily identified by its task number, DG-5049. This DG is proposed Revision 1 of Regulatory Guide (RG) 5.51, “Management Review of Nuclear Material Control and Accounting Systems.”

This DG provides guidance that conforms with revisions to 10 CFR part 74, “Material Control and Accounting of Special Nuclear Material,” as well as incorporates experience gained since the RG was initially published in June 1975. In particular, the guidance for performing independent assessments has been expanded to include process monitoring and item monitoring for Category I fuel cycle facilities, and to include guidance for uranium enrichment facilities. In addition, this revision addresses changes in MC&A terminology since the RG was published in 1975; for example, the term “management review” has been replaced by “independent assessment,” and “material unaccounted for” by “inventory difference.”

III. Backfitting

This DG provides guidance on recordkeeping and reporting requirements with respect to material control and accounting, as set forth in 10 CFR part 74. The regulatory position held in this guidance demonstrates the method that the NRC staff finds acceptable for an applicant or licensee to meet the requirements of the underlying NRC regulations. The issuance of the guidance in this DG is not backfitting, as that term is defined in 10 CFR 70.76, 72.62, or 76.76, because information collection and reporting requirements with respect to material control and accounting are not included within the scope of the NRC's backfitting protections.

Dated at Rockville, Maryland, this 11th day of September, 2015.
