Letter from P.R. Simpson (Constellation Energy Generation, LLC) to U. S.

Nuclear Regulatory Commission, " License Amendment Request Regarding Transition to GNF3 Fuel," dated August 18, 2022 (ADAMS Accession No. ML22230C927)

By letter dated August 18, 2022 (Reference), Constellation Energy Generation, LLC ( CEG) requested an amendment to Renewed Facility Operating License Nos. DPR-19 and DPR-25 for Dresden Nuclear Power Station (DNPS), Units 2 and 3, respectively. The proposed change supports the transition from Framatome, Inc. ATRIUM 10XM fuel to Global Nuclear Fuel -

Americas, LLC (GNF/GNF-A) GNF3 fuel at DNPS by adding the GNF Methods to Technical Specifications (TS) 5.6.5.

The NRC requested clarification on the implementation schedule for the amendment since the DNPS units have different outages years. This letter provides clarity on the implementation of the proposed amendment. The DNPS TS apply to both units. The following statement replaces the implementation schedule included in the Reference letter. The changes to TS 5.6.5 will be implemented during the fall of 2023 outage to support the Unit 2 initial transition to GNF3 fuel.

Unit 3 will transition to GNF3 fuel starting with the fall 2024 refueling outage and continue to use Framatome TS methods until that transition occurs.

CEG has reviewed the information supporting the No Significant Hazards Consideration and the Environmental Consideration that was previously provided to the NRC in the Reference. The additional information provided in the submittal does not affect the conclusion that the proposed license amendment does not involve a significant hazards consideration. This additional information also does not affect the conclusion that neither an environmental impact statement nor an environmental assessment need be prepared in support of the proposed amendment.

In accordance with 10 CFR 50.91, "Notice for public comment; State consultation,"

paragraph (b), CEG is notifying the State of Illinois of this application for license amendment by transmitting a copy of this letter and its attachments to the designated State Officials.
