By the late 1980s, revelations of contamination, unsafe practices, and secrecy at nuclear weapons plants such as Hanford in Washington and Rocky Flats in Colorado had shaken public confidence. Because the Nuclear Regulatory Commission does not regulate the government's own weapons facilities, Congress created the Defense Nuclear Facilities Safety Board in the defense authorization law signed on September 29, 1988, as an independent check on the Energy Department. The board has five members, experts in nuclear safety, appointed by the President and confirmed by the Senate to five-year terms.
The board's engineers and resident inspectors monitor safety at sites that design, build, maintain, and dismantle nuclear weapons and clean up their wastes, including Los Alamos, Pantex in Texas, the Y-12 complex in Tennessee, Savannah River in South Carolina, and Hanford. It reviews designs of new facilities, investigates incidents, and issues formal recommendations to the Secretary of Energy, who must respond publicly and in writing. Like other safety boards, it has no power to shut down operations or issue fines, and it relies on transparency and persuasion.
The board's influence has been tested by Energy Department efforts to limit its access to some facilities and information, including a 2018 order that the board said weakened its oversight, which was later revised. It has repeatedly lacked a quorum, and proposals have been made to shrink or restructure it. As the government expands production of plutonium pits for new warheads and continues decades-long cleanup projects, supporters say independent safety oversight is more important than ever, while critics in government have argued that the board duplicates the Energy Department's own safety work.
