Fresh and Spent Fuel Pool Criticality Analyses
The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment draft regulatory guide (DG), DG-1373, ``Fresh and Spent Fuel Pool Criticality Analyses.'' This draft guide, if finalized as a new regulatory guide (RG), would update and supersede Interim Staff Guidance DSS-ISG-2010-01, ``Staff Guidance Regarding the Nuclear Criticality Safety Analysis for Spent Fuel Pools.'' This draft guide describes an approach that the NRC staff considers acceptable to demonstrate that NRC regulatory requirements are met for subcriticality of fuel assemblies stored in fresh fuel vaults and spent fuel pools at light-water reactor power plants. It endorses, with clarifications and exceptions, the Nuclear Energy Institute (NEI) guidance document NEI 12-16, ``Guidance for Performing Criticality Analyses of Fuel Storage at Light-Water Reactor Power Plants,'' Revision 4.
Exelon Generation Company, LLC; Byron Station, Unit Nos. 1 and 2; Braidwood Station, Units 1 and 2
The U.S. Nuclear Regulatory Commission (NRC) is issuing an exemption in response to a September 30, 2019, request from Exelon Generation Company, LLC (Exelon) from regulatory requirements to allow Byron Station, Unit Nos. 1 and 2, and Braidwood Station, Units 1 and 2, to use an alternative methodology for determining reactor coolant system pressure-temperature limits. The methodology is described in AREVA NP Topical Report BAW-2308, Revisions 1-A and 2-A, ``Initial RTNDT of Linde 80 Weld Materials.''
In the Matter of LaCrosse Solutions, LLC; La Crosse Boiling Water Reactor
The U.S. Nuclear Regulatory Commission (NRC) is issuing an Order to extend the effectiveness of a September 24, 2019, Order, which approved the direct transfer of Possession Only License No. DPR-45 for the La Crosse Boiling Water Reactor (LACBWR) from the current holder, LaCrosseSolutions, LLC, to Dairyland Power Cooperative and approved a conforming license amendment, for six months beyond its current September 24, 2020, expiration date.
EnergySolutions Services, Inc.
The Nuclear Regulatory Commission (NRC) received and is considering issuing an export license (XW026) requested by EnergySolutions Services Inc. (ESSI). On July 27, 2020, ESSI filed an application with the NRC for a license to export low-level radioactive waste to Mexico. The NRC is providing notice of the opportunity to comment, request a hearing, and petition to intervene on ESSI's application.
Biweekly Notice; Applications and Amendments to Facility Operating Licenses and Combined Licenses Involving no Significant Hazards Considerations
Pursuant to section 189.a.(2) of the Atomic Energy Act of 1954, as amended (the Act), the U.S. Nuclear Regulatory Commission (NRC) is publishing this regular biweekly notice. The Act requires the Commission to publish notice of any amendments issued, or proposed to be issued, and grants the Commission the authority to issue and make immediately effective any amendment to an operating license or combined license, as applicable, upon a determination by the Commission that such amendment involves no significant hazards consideration (NSHC), notwithstanding the pendency before the Commission of a request for a hearing from any person. This biweekly notice includes all amendments issued, or proposed to be issued, from August 11, 2020, to August 24, 2020. The last biweekly notice was published on August 25, 2020.
Applications and Amendments to Facility Operating Licenses and Combined Licenses Involving Proposed No Significant Hazards Considerations and Containing Sensitive Unclassified Non-Safeguards Information and Order Imposing Procedures for Access to Sensitive Unclassified Non-Safeguards Information
The U.S. Nuclear Regulatory Commission (NRC) received and is considering approval of two amendment requests. The amendment requests are for Oconee Nuclear Station, Units 1, 2, and 3 and Beaver Valley Power Station, Unit 2. For each amendment request, the NRC proposes to determine that they involve no significant hazards consideration. Because each amendment request contains sensitive unclassified non- safeguards information (SUNSI) an order imposes procedures to obtain access to SUNSI for contention preparation.
