NUCLEAR REGULATORY COMMISSION 10 CFR Part 50
[NRC-2022-0159]
Regulatory Guide: Maintenance, Testing, and Replacement of Vented Lead-Acid Storage Batteries for Production and Utilization Facilities AGENCY: Nuclear Regulatory Commission.
ACTION: Final guide; issuance.
SUMMARY
- The U.S. Nuclear Regulatory Commission (NRC) is issuing Revision 4 of Regulatory Guide (RG) 1.129, Maintenance, Testing, and Replacement of Vented Lead-Acid Storage Batteries for Production and Utilization Facilities. This revised guidance provides information to manage vented lead-acid battery degradation such that a battery in service would retain its readiness for supporting design-basis events. It endorses, with certain clarifying regulatory positions, Institute of Electrical and Electronics Engineers (IEEE) Standard (Std.) 450-2020, which provides the recommended maintenance, test schedules, and testing procedures intended to optimize the life and performance of permanently installed vented lead-acid storage batteries used for standby power applications. It also provides guidance to determine when batteries should be replaced.
DATES: Revision 4 to RG 1.129 is available on March 27, 2023.

SUPPLEMENTARY INFORMATION I. Discussion The NRC is issuing a revision to an existing guide in the NRCs Regulatory Guide series. This series was developed to describe methods that are acceptable to the NRC staff for implementing specific parts of the agencys regulations, to explain techniques that the staff uses in evaluating specific issues or postulated events, and to describe information that the staff needs in its review of applications for permits and licenses.
Revision 4 of RG 1.129 was issued with a temporary identification number of DG-1401 (ADAMS Accession No. ML22026A441).
Revision 4 of RG 1.129 describes an approach that may be used to determine quality standards acceptable to the NRC staff to meet the regulatory requirements provides guidance to manage vented lead-acid battery degradation such that a battery in service would retain its readiness for supporting design-basis events. Revision 4 of RG 1.129 also endorses, with certain clarifying regulatory positions, IEEE Std. 450-2020, which provides the recommended maintenance, test schedules, and testing procedures intended to optimize the life and performance of permanently installed vented lead-acid storage batteries used for standby power applications. It also provides guidance to determine when batteries should be replaced.
II. Additional Information The NRC issued RG 1.129, Revision 3, in September 2013, to endorse (with certain clarifying regulatory positions) IEEE Std. 450-2010. Since then, IEEE has revised the standard as IEEE Std. 450-2020 to provide clarifying guidance on 3
maintenance, testing, and corrective actions. The revised IEEE standard provides guidance for the condition monitoring of stationary batteries. The staff determined that, based on the revised IEEE standard, a revision to this RG is necessary for guidance to support new license applications, design certifications, and applications for license amendments.
The NRC published a notice of availability of DG-1401 in the Federal Register on August 29, 2022 (87 FR 52814) for a 30-day public comment period. There were no comments from the public submitted for DG-1401, and no staff responses were needed.
As noted in the Federal Register on December 9, 2022 (87 FR 75671), this document is being published in the Rules section of the Federal Register to comply with publication requirements under 1 CFR chapter I.
III. Congressional Review Act This RG is a rule as defined in the Congressional Review Act (5 U.S.C. 801-808).
However, the Office of Management and Budget has not found it to be a major rule as defined in the Congressional Review Act.
IV. Backfitting, Forward Fitting, and Issue Finality Issuance of RG 1.129, Revision 4 does not constitute backfitting as defined in section 50.109 of title 10 of the Code of Federal Regulations (10 CFR), Backfitting, and as described in NRC Management Directive (MD) 8.4, Management of Backfitting, Forward Fitting, Issue Finality, and Information Requests (ADAMS Accession No. ML18093B087); constitute forward fitting as that term is defined and described in MD 8.4; or affect the issue finality of any approval issued under 10 CFR part 52, Licenses, Certificates, and Approvals for Nuclear Power Plants. As explained in RG 1.129, Revision 4, applicants and licensees are not required to comply with the positions set forth in this regulatory guide.

V. Submitting Suggestions for Improvement of Regulatory Guides A member of the public may, at any time, submit suggestions to the NRC for improvement of existing RGs or for the development of new RGs. Suggestions can be submitted on the NRCs public website at https://www.nrc.gov/reading-rm/doc-collections/reg-guides/contactus.html. Suggestions will be considered in future updates and enhancements to the Regulatory Guide series.
