Nuclear Regulatory Commission.


Draft regulatory guide; request for comment.


The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment draft regulatory guide (DG), DG-5057, “Special Nuclear Material Control and Accounting System for Non-Fuel Cycle Facilities.” This DG provides guidance to licensees and applicants on the NRC's regulations concerning the material control and accounting of special nuclear material. The need for this guidance arises from an ongoing NRC rulemaking to revise these regulations, as discussed further in Section II below. The scope of DG-5057 covers nuclear power plants and all non-fuel cycle facilities.


Submit comments by June 15, 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.

II. Additional Information

The NRC is conducting a rulemaking to revise part 74 of Title 10 of the Code of Federal Regulations (10 CFR), “Material Control and Accounting of Special Nuclear Material,” and in this regard published on November 8, 2013 (78 FR 67225) a proposed rule for comment. The rulemaking to revise the material control and accounting (MC&A) regulations was initially authorized by a 2009 staff requirements memorandum (SRM) to SECY-08-0059, “Rulemaking Plan: Part 74—Material Control and Accounting of Special Nuclear Material.” The SRM and SECY-08-0059 may be found in ADAMS under Accession Nos. ML090360473 and ML080580307, respectively. The SRM directed the NRC staff to revise existing MC&A guidance documents to reflect any new and revised requirements.

The draft guidance that the NRC is issuing for public comment is a DG in the NRC's “Regulatory Guide” series. This series was developed to describe and make available to the public technical information, such as 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 “Special Nuclear Material Control and Accounting System for Non-Fuel Cycle Facilities,” is temporarily identified by its task number, DG-5057. This DG-5057 is proposed revision 3 of RG 5.29. Revision 3 of RG 5.29 considers conformance with the provisions of American National Standards Institute (ANSI) N15.8 2009, “Methods of Nuclear Material Control—Material Control Systems—Special Nuclear Material Control and Accounting Systems for Nuclear Power Plants,” to be an acceptable approach to meet the MC&A requirements in subpart B of 10 CFR part 74 at nuclear power plants. DG-5057 expands the scope of the guidance to cover the proposed new requirements in subpart A of 10 CFR part 74 and to cover all non-fuel cycle facilities.

III. Backfitting and Issue Finality

Draft Guide-5057 provides guidance on MC&A recordkeeping and reporting requirements, as set forth in 10 CFR part 74. The regulatory guidance held in this guidance provides methods 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 DG-5057 is not backfitting, as that term is defined in 10 CFR 50.109, 70.76, or 72.62, or inconsistent with the issue finality provisions in 10 CFR part 52, 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 or part 52 issue finality provisions.

Applicants and potential applicants are not, with certain exceptions, protected by any issue finality provisions under part 52. This is because the issue finality provisions under part 52, with certain exclusions discussed below, were not intended to apply to every NRC action which substantially changes the expectations of current and future applicants. The exceptions to the general principle are whenever an applicant references a part 52 license (e.g., an early site permit) and/or NRC regulatory approval (e.g., a design certification rule, a standard design approval) with specified issue finality provisions. However, the scope of issue finality provided extends only to the matters resolved in the license or regulatory approval. Early site permits, design certification rules, and standard design approvals do not address or resolve compliance with material control and accounting requirements in 10 CFR part 74. Therefore, no applicant referencing an early site permit, design certification rule, or standard design approval is protected by relevant issue finality provisions with respect to the material control and accounting matters addressed in DG-5057.
