Senate confirms Creedon at NNSA

The Senate confirmed a new second-in-command for the agency in charge of the safety, reliability and performance of the U.S. nuclear device and materials stockpile.

Madelyn Creedon was confirmed July 23 as the Department of Energy’s principal deputy administrator for the National Nuclear Security Administration.

Nominated for the position last November, Creedon will support NNSA Administrator Frank Klotz in managing the agency and contribute on policy matters across the DOE and NNSA enterprise. NNSA was created in 1999 as a semi-autonomous agency operating under DOE.

“Madelyn Creedon’s confirmation comes at a critical point for the National Nuclear Security Administration,” Energy Secretary Ernest Moniz said in a statement following her confirmation. “She is well-prepared for her new role at the department.”

Creedon had served as assistant secretary of Defense for global strategic affairs since 2011, where she oversaw policy development and execution in the areas of countering weapons of mass destruction, U.S. nuclear forces and missile defense, as well as DoD cybersecurity and space issues.

She has also served as counsel for the Democratic staff on the Senate Armed Services Committee. In 2000, she left the Armed Services panel to become deputy administrator for defense programs at the NNSA, and returned to the committee in January 2001. Prior to joining the Armed Services Committee staff in March 1997, she was associate deputy secretary of Energy for national security programs, beginning in October 1995.
