New security leaders appointed at nuclear site

(AP) The security contractor at a Tennessee plant that stores the nation's supply of highly enriched uranium has appointed an acting general manager almost two weeks after three protesters, including an 82-year-old nun, got into a high-security area.

Officials say the protesters on July 28 were found hanging banners in the dark, singing and offering to break bread with the security guards at Y-12 Oak Ridge National Security Complex in Knoxville. They were arrested and officials say all nuclear materials are safe.

WSI-Oak Ridge confirmed to the Knoxville News Sentinel (http://bit.ly/MqW3ex ) Wednesday that Steven C. Hafner will replace the removed Lee Brooks as general manager

The Y-12 Protective Force director, Gary Brandon, also was relieved of duty. Both he and Brooks will be reassigned.

The plant provides nuclear fuel for the Navy and research reactors worldwide.
