Two weeks after an unprecedented security breach, two top executives have retired from the company that manages the Y-12 National Security Complex, and one of them has been replaced.
In a press release, The Babcock and Wilcox Co. announced that Charles “Chuck” G. Spencer is now acting president and general manager for Babcock & Wilcox Technical Services Y-12 LLC, the contractor that manages the plant for the National Nuclear Security Administration. He replaces Darrel P. Kohlhorst, who has retired.
It said William R. Klemm, deputy general manager of operations, has also retired.
The statement didn’t say whether the staff changes were related to the highly publicized July 28 intrusion by three anti-nuclear weapons activists, and it didn’t say who would replace Klemm.
