NRC Bulletin 2012-01: Design Vulnerability in Electric Power System
The U.S. Nuclear Regulatory Commission (NRC) is issuing this notice to inform all holders of operating licenses and combined licenses for nuclear power reactors of the closure of ``NRC Bulletin 2012-01: Design Vulnerability in Electric Power System'' (Bulletin). NRC has completed evaluations and inspections of the responses and other actions taken by the licensees of the nuclear power plants in response to NRC Bulletin 2012-01. The staff has approved the actions to be taken by the licensee for Vogtle Units 3 and 4 following commencement of operations and will inspect these actions under the Reactor Oversight Process. The NRC staff concludes that any potential adverse impact on nuclear plant safety due to an open phase condition (OPC) in the plant offsite power system has been adequately addressed by the licensees.
Draft Regulatory Guide: Sizing of Large Lead-Acid Storage Batteries
The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment a draft regulatory guide (DG), DG-1418, ``Sizing of Large Lead-Acid Storage Batteries.'' This DG is proposed Revision 2 of Regulatory Guide (RG) 1.212 of the same name. DG-1418 describes an approach that is acceptable to the NRC staff to meet regulatory requirements for sizing of large lead-acid storage batteries for production and utilization facilities. It endorses, with clarifications, the Institute of Electrical and Electronic Engineers (IEEE) Standard 485-2020, ``IEEE Recommended Practice for Sizing Lead- Acid Batteries for Stationary Applications.''
American Society of Mechanical Engineers Code Cases and Update Frequency
The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its regulations to incorporate by reference proposed revisions of three regulatory guides, which would approve new, revised, and reaffirmed code cases published by the American Society of Mechanical Engineers. This proposed action would allow nuclear power plant licensees and applicants for construction permits, operating licenses, combined licenses, standard design certifications, standard design approvals, and manufacturing licenses to use the code cases listed in these draft regulatory guides as voluntary alternatives to engineering standards for the construction, inservice inspection, and inservice testing of nuclear power plant components. The NRC is requesting comments on this proposed rule and on the draft versions of the three regulatory guides proposed to be incorporated by reference. The NRC also is making available a related draft regulatory guide that lists code cases that the NRC has not approved for use. This draft regulatory guide will not be incorporated by reference into the NRC's regulations. In addition, this rulemaking proposes to extend the time periods required for licensees to update their codes of record.
