Former NNSA head joins Bulletin of Atomic Scientists

By ExchangeMonitor

Jill Hruby, the most recent administrator of the Department of Energy’s semi-autonomous National Nuclear Security Administration, recently joined the Bulletin of Atomic Scientists’ Science and Security Board, the organization announced last week.

“I’m honored to join the Bulletin’s Science and Security Board at such a pivotal moment for nuclear affairs worldwide,” Hruby said in the release from July 16. “I hope to help sustain a vital community of experts focused on these complex challenges—and to foster deeper public understanding of the risks that shape our global security.”

Prior to starting her role in 2021 as the head of the organization in charge of refurbishing the nation’s nuclear weapons stockpile during the Joe Biden administration, Hruby was at Sandia National Laboratories for 34 years and served as the laboratories’ director from 2015 to 2017. From 2018 to 2021 Hruby was a distinguished fellow at the Washington-based nonprofit Nuclear Threat Initiative.

Hruby’s honors include the Department of Energy Secretary’s Exceptional Service Award, the National Nuclear Security Administration’s Distinguished Service Gold Award, and the Office of the Secretary of Defense Medal for Exceptional Public Service.

The Bulletin of Atomic Scientists is an independent nonprofit that focuses on nuclear risk, climate change and disruptive technologies. It was created in 1945 by University of Chicago scientists and nuclear bomb pioneers, Albert Einstein and J. Robert Oppenheimer, and is well known for its Doomsday Clock, a symbolic device the Bulletin of Atomic Scientists uses to signify closeness to “global catastrophe.”
