A three-judge panel heard the case -- Orange County v. U.S. Nuclear Regulatory Commission -- over the potential danger of waste storage pools at Carolina Power & Light Co.'s Shearon Harris Nuclear Power Plant.
Orange County is seeking a full environmental impact study on the potential consequences of these pools.
Diane Curran, attorney for Orange County, said the county appealed to the U.S. Court of Appeals when the NRC refused to grant it a hearing and prepare an environmental impact statement regarding the site.
"The NRC has never prepared an environmental impact statement that looks at the effects of partial drainage," she said. "We're still hoping for our hearing."
She said no decision from the Court of Appeals is expected in the near future.
Curran said there is a concern that if pools are partially drained, nuclear fuel cells could be exposed to air and would burn a radioactive fire.
She said the Nuclear Regulatory Commission argues that the county has not shown how a fire could occur.
Keith Poston, spokesman for CP&L, said the NRC and the Atomic Safety and Licensing Board studied the condition of the pools between 1999 and 2001.
Poston said he expects the panel to reject the county's appeal.
