DOCKET NUMBER 50-483 CALLAWAY PLANT UNIT 1 UNION ELECTRIC CO.
RENEWED FACILITY OPERATING LICENSE NPF-30 PRESENTATION INFORMATION FOR PRE-APPLICATION MEETING REGARDING TRANSITION TO ADVANCED WESTINGHOUSE FUEL AND UPGRADE OF ANALYTICAL METHODS AT CALLAWAY PLANT A meeting between Union Electric (Ameren Missouri), Westinghouse Electric Corporation (WEC) and NRC personnel is being planned for the purpose of discussing a license amendment request (LAR) to be submitted in the November 2025 timeframe for the Callaway Plant, Unit 1 (Callaway). The forthcoming meeting is intended to address the licensing aspects of a fuel transition project and solicit inquiries and insights from the NRC staff.
The proposed license amendment has the following major themes: transition to an upgraded fuel assembly design with improved materials, adoption of improved analysis methods, an incremental increase in allowable fuel burnup, and adoption of TSTF-51, TSTF-471 and TSTF-571. These changes provide a more robust fuel product with accident tolerant features, a supporting safety analysis that conforms to current regulatory guidance, and increased operational flexibility.
From preparation of the presentation materials to be used for the anticipated pre-application meeting, it was determined that some of the discussions are likely to include or describe information that is proprietary to WEC. On that basis, the pre-application meeting is being planned as partly a public meeting and partly a closed meeting.
The presentation materials to be used for the open portion of the meeting are in the form of PowerPoint "slides" prepared by Ameren and WEC personnel. These slides contain no proprietary content. The purpose of this letter is to transmit the slides to the NRC staff in advance of the meeting.
The set of slides to be used for the public meeting is provided as Enclosure 1. No slides were prepared for the closed portion of the meeting.
