⚛️License Amendment Proposal for Nine Mile Point Nuclear Station

Constellation Energy Generation, LLC; Nine Mile Point Nuclear Station, Unit 2; License Amendment Request

Summary

The U.S. Nuclear Regulatory Commission (NRC) is considering issuance of an amendment to Renewed Facility Operating License (RFOL) No. NPF-69, issued to Constellation Energy Generation, LLC (CEG, or the licensee) for operation of the Nine Mile Point Nuclear Station, Unit 2, located in Oswego, New York. The proposed license amendment would revise the technical specifications (TS) to eliminate the requirement for automatic main steam line (MSL) isolation based on the temperature in the area around the MSL. In lieu of automatic isolation, a new specification is proposed that requires manual action when the MSL area temperature is above the limit.
