U.S. Secretary of Energy Rick Perry plans to visit the Savannah River lab near Aiken on Friday.

The stop comes in the wake of a recent legal win by S.C. Attorney General Alan Wilson to force the federal agency to start disposing weapons-grade plutonium on the site.

The Department of Energy is billing the visit as an "all-hands meeting" with employees of both the Savannah River National Laboratory and the Savannah River Site. It will include remarks from Perry and a question-and-answer session at 1:45 p.m., according to a DOE new release.

The removal of 12 tons of highly radioactive plutonium from the site has been a long-running issue. The material was moved to the site from other nuclear defense sites in the 1990s with the understanding the plant would turn it into commercial nuclear fuel.

The program never got going, and the federal government had agreed to move the material out of state if it didn't.

Wilson last year won a ruling that DOE must remove a ton of plutonium within the next two years, consistent with the original agreement.
