II. Discussion

The NRC is issuing for public comment draft Supplement 62 to the GEIS for License Renewal of Nuclear Plants, NUREG-1437, regarding the proposed renewal of Facility Operating License Nos. DPR-80 and DPR-82 for an additional 20 years for Diablo Canyon. Draft Supplement 62 to the GEIS includes the NRC staff's evaluation of the environmental impacts of the proposed action and alternatives to the proposed action. The NRC staff's preliminary recommendation is that the adverse environmental impacts of license renewal for Diablo Canyon are not so great that preserving the option of license renewal for energy-planning decisionmakers would be unreasonable.
