NRC issues supplemental EIS for 20-year Grand Gulf license renewal

The Nuclear Regulatory Commission (NRC) has issued its final supplemental environmental impact statement (EIS) for the proposed 20-year renewal of the operating license for the Entergy (NYSE:ETR) Grand Gulf nuclear power plant in Mississippi.

The report concludes there are no environmental impacts that would preclude renewing the plant’s license. NRC announced the action Dec. 2.

The Grand Gulf plant is a single boiling water reactor located in Port Gibson, about 20 miles south of Vicksburg. GenerationHub records indicate that it has an operating capacity of roughly 1,250 MW. The data shows that Grand Gulf had a capacity factor of about 61% in 2012.

It is licensed to operate through Nov. 1, 2024. Entergy Nuclear applied on Nov. 1, 2011, to renew the license for an additional 20 years.

The license renewal review process proceeds along two tracks – one for review of safety issues and another for environmental issues.

As part of the environmental review of the application, the NRC held public meetings near the plant to discuss the review process and the draft version of the environmental impact statement, which was published in November 2013. Comments were received and considered from members of the public, local officials, and representatives of state and federal agencies, NRC said.

Potential license renewal of Grand Gulf and other nuclear plants started moving forward again in September when NRC issued its continued storage rule that addresses long-term on-site storage of spent nuclear fuel at plant sites.
