BWXT Y-12 Names Steve Liedle Acting General Manager of Y-12 National Security Complex.

LYNCHBURG, Va. -- BWX Technologies, Inc. ("BWXT") announces that Steve Liedle has been named Acting General Manager for the Y-12 National Security Complex. Liedle replaces Dennis R. Ruddy, until a permanent General Manager is appointed.

Liedle has served as Deputy General Manager

for BWXT Y-12 since January 2004. Prior to joining BWXT Y-12, Liedle had served as President and General Manager at both the Bechtel Jacobs Company and Bechtel Nevada. "Liedle's successful experience managing complex projects for the Department of Energy makes him an excellent choice for leading Y-12 during this interim period," said John A. Fees, President and Chief Operating Officer of BWXT.

The National Nuclear Security Administration ("NNSA") recently awarded BWXT Y-12 a five-year contract extension to manage and operate the Y-12 National Security Complex. "I appreciate the confidence that the NNSA has shown in awarding us the extension. We look forward to another five years of success at Y-12 and I am confident that the change in personnel will have no influence on the facility's operations. Significant transformation of the Y-12 site has occurred under BWXT's management, of which, Denny Ruddy was a part. BWXT has established high expectations for furthering this progress over the next five years," said Fees. BWXT is working closely with the DOE, NNSA and Bechtel to guarantee a successful transition in management.
