The Defense Nuclear Facilities Safety Board, the independent agency responsible for ensuring that Department of Energy facilities are protective of public health and safety, announced that the board’s acting chairman, Thomas Summers, has concluded his service with the agency, having completed his second term as a board member on October 18.
Summers’ departure leaves Patricia Lee, who joined the DNFSB after being confirmed by the Senate in July 2024, as the board’s only remaining member and acting chair. Lee’s DNFSB board term ends in October 2027.

This summer’s release of Oppenheimer, the major Hollywood movie by Christopher Nolan, has brought renewed attention to J. Robert Oppenheimer’s thoughts, concerns, and intentions regarding the U.S. pursuit of thermonuclear weapons. This paper provides context surrounding the 1949 recommendation of the Atomic Energy Commission’s General Advisory Committee, chaired by Oppenheimer, against a crash program for hydrogen bombs, a recommendation that would be used against him in the 1954 decision to revoke his security clearance. An appendix reproduces the April 5, 2022, letter from Los Alamos National Laboratory directors to the secretary of energy. In December 2022, Secretary of Energy Granholm vacated the original security review board decision.
