Exelon Generation Company, LLC; Calvert Cliffs Nuclear Power Plant; Independent Spent Fuel Storage Installation
The U.S. Nuclear Regulatory Commission (NRC) is considering an exemption request from Exelon Generation Company, LLC (EGC) to allow the Calvert Cliffs Nuclear Power Plant (CCNPP) to load spent fuel with a larger pellet diameter than is authorized in the Holtec International, Inc. (Holtec) HI-STORM FW storage system in Certificate of Compliance No. 1032, Amendment No. 1, Revision 1. The NRC prepared an environmental assessment (EA) documenting its finding. The NRC concluded that the proposed action would have no significant environmental impact. Accordingly, the NRC staff is issuing a finding of no significant impact (FONSI) associated with the proposed exemption.
