Duke Energy Carolinas LLC; McGuire Nuclear Station Units 1 and 2; Independent Spent Fuel Storage Installation

摘要

The U.S. Nuclear Regulatory Commission (NRC) is considering an exemption request from Duke Energy Carolinas, LLC (Duke Energy) which would permit Duke Energy to maintain MAGNASTOR[supreg] Cask 0FCTKN045 at its McGuire Nuclear Station independent spent fuel storage installation (ISFSI) in a storage condition where the helium density is above the range specified in Certificate of Compliance No. 1031, Amendment No. 7, Technical Specification 3.1.1. The NRC prepared an environmental assessment (EA) documenting its finding 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.
