Start Preamble

AGENCY:

Nuclear Regulatory Commission.

ACTION:

Draft regulatory guide, request for comment.

SUMMARY:

The U.S. Nuclear Regulatory Commission (NRC) is issuing draft regulatory guide (DG), DG-1311, “Sizing of Large Lead-Acid Batteries” for public comment. This guidance is proposed revision 1 of regulatory guide (RG), RG 1.212, “Sizing of Large Lead-Acid Storage Batteries.” This DG endorses, with certain clarifications, the Institute of Electrical and Electronic Engineers (IEEE) Standard 485-2010, “IEEE Recommended Practice for Sizing Lead-Acid Batteries for Stationary Applications.” This DG describes methods acceptable to the NRC staff for complying with the design requirements for stationary battery applications in full float operation for nuclear power plants.

DATES:

Submit comments by June 19, 2015. Comments received after this date will be considered if 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 such information 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 problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses.

The DG, entitled, “Sizing of Large Lead Acid Storage Batteries” is temporarily identified by its task number, DG-1311. This DG-1311 is proposed revision 1 of RG 1.212. This DG endorses, with certain clarifications, IEEE Standard 485-2010, “IEEE Recommended Practice for Sizing Lead-Acid Batteries for Stationary Applications.” This DG describes methods acceptable to the staff for complying with the design requirements for stationary battery applications in full float operation for nuclear power plants.

Copies of IEEE standards may be purchased from the Institute of Electrical and Electronics Engineers Service Center, 445 Hoes Lane, P.O. Box 1331, Piscataway, NJ 08855, or through the IEEE's public Web site at http://www.ieee.org/​publications_​standards/​index.html.

III. Backfitting and Issue Finality

Issuing of this DG, if finalized, would not constitute backfitting as defined in § 50.109 of Title 10 of the Code of Federal Regulations (10 CFR), (the Backfit Rule), and would not otherwise be inconsistent with the issue finality provisions in 10 CFR part 52. As discussed in the “Implementation” section of this DG, the NRC has no current intention to impose this DG on current holders of Part 50 operating licenses or Part 52 combined licenses.

This DG, if finalized, could be applied to applications for operating licenses and combined licenses docketed by the NRC as of the date of issuance of the final RG, as well as future applications for operating licenses and combined licenses submitted after the issuance of the RG. Such action would not constitute backfitting as defined in 10 CFR 50.109(a)(1) or be otherwise inconsistent with the applicable issue finality provision in 10 CFR part 52, inasmuch as such applicants or potential applicants, with exceptions not applicable here, are not within the scope of entities protected by the Backfit Rule or the relevant issue finality provisions in part 52.

Start Signature

Dated at Rockville, Maryland, this 14th day of April, 2015.

For the Nuclear Regulatory Commission.

Harriet Karagiannis,

Acting Chief, Regulatory Guidance and Generic Issues Branch, Division of Engineering, Office of Nuclear Regulatory Research.
