<NOTICE> NUCLEAR REGULATORY COMMISSION <DEPDOC>[NRC-2025-1930]</DEPDOC> <SUBJECT>Applications for Amendments to Facility Operating Licenses Involving Proposed No Significant Hazards Consideration Determination and Containing Sensitive Unclassified Non-Safeguards Information and Order Imposing Procedures for Access to Sensitive Unclassified Non-Safeguards Information</SUBJECT> <HD SOURCE="HED">AGENCY:</HD> Nuclear Regulatory Commission. <HD SOURCE="HED">ACTION:</HD> License amendment request; notice of opportunity to comment, request a hearing, and petition for leave to intervene; order imposing procedures. <SUM> <HD SOURCE="HED">SUMMARY:</HD> The U.S. Nuclear Regulatory Commission (NRC) received and is considering approval of three amendment requests. The amendment requests are for Braidwood Station, Units 1 and 2, and Byron Station, Units 1 and 2; Catawba Nuclear Station, Units 1 and 2, and McGuire Nuclear Station, Units 1 and 2; and Limerick Generating Station, Units 1 and 2. For each amendment request, the NRC proposes to determine that it involves no significant hazards consideration (NSHC). Because each amendment request contains sensitive unclassified non-safeguards information (SUNSI), the NRC is issuing an order imposing procedures to obtain access to SUNSI for contention preparation by persons who file a hearing request or petition for leave to intervene. </SUM> <DATES> <HD SOURCE="HED">DATES:</HD> Comments must be received by January 29, 2026. A request for a hearing or petitions for leave to intervene must be filed by March 2, 2026.

Background</HD> Pursuant to section 189a.(1)-(2) of the Atomic Energy Act of 1954, as amended (the Act), the NRC is publishing this 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 NSHC, notwithstanding the pendency before the Commission of a request for a hearing from any person. This notice includes notices of amendments containing SUNSI. <HD SOURCE="HD1">III. Notice of Consideration of Issuance of Amendments to Facility Operating Licenses, Proposed No Significant Hazards Consideration Determination, and Opportunity for a Hearing</HD> The Commission has made a proposed determination that the following amendment requests involve NSHC. Under the Commission's regulations in 10 CFR 50.92, this means that operation of the facility in accordance with the proposed amendments would not (1) involve a significant increase in the probability or consequences of an accident previously evaluated, or (2) create the possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reduction in a margin of safety. The basis for this proposed determination for each amendment request is shown as follows. The Commission is seeking public comments on these proposed determinations. Any comments received within 30 days after the date of publication of this notice will be considered in making any final determination. Normally, the Commission will not issue the amendments until the expiration of 60 days after the date of publication of this notice. The Commission may issue any of these license amendments before expiration of the 60-day period provided that its final determination is that the amendments involve no significant hazards consideration. In addition, the Commission may issue any of these amendments prior to the expiration of the 30-day comment period if circumstances change during the 30-day comment period such that failure to act in a timely way would result, for example, in derating or shutdown of the facility. If the Commission takes action on any of these amendments prior to the expiration of either the comment period or the notice period, it will publish a notice of issuance in the <E T="04">Federal Register</E> . If the Commission makes a final no significant hazards consideration determination for any of these amendments, any hearing on those amendments will take place after issuance. The Commission expects that the need to take this action will occur very infrequently. <HD SOURCE="HD2">A. Opportunity To Request a Hearing and Petition for Leave To Intervene</HD> Within 60 days after the date of publication of this notice, any person (petitioner) whose interest may be affected by any of these actions may file a request for a hearing and petition for leave to intervene (petition) with respect to that action. Petitions shall be filed in accordance with the Commission's “Agency Rules of Practice and Procedure” in 10 CFR part 2. Interested persons should consult a current copy of 10 CFR 2.309. If a petition is filed, the Commission or a presiding officer will rule on the petition and, if appropriate, a notice of a hearing will be issued. Petitions must be filed no later than 60 days from the date of publication of this notice in accordance with the filing instructions in the “Electronic Submissions (E-Filing)” section of this document. Petitions and motions for leave to file new or amended contentions that are filed after the deadline will not be entertained absent a determination by the presiding officer that the filing demonstrates good cause by ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Preview showing 10k of 35k characters.
