Riepilogo

The U.S. Nuclear Regulatory Commission (NRC) is considering an exemption request from Arizona Public Service Company to allow the Palo Verde Nuclear Generating Station to load spent fuel with a larger pellet diameter than is authorized in the MAGNASTOR[supreg] storage cask system in Certificate of Compliance No. 1031, Amendment No. 7. 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.
