DNFSB’s Summers ends board tenure, extending agency’s loss of quorum
Lee
Summers
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.

The Large Helical Device (LHD) is a big non-tokamak type superconducting toroidal fusion facility. In both areas of the physics and technology, the LHD project is expected to contribute to the exploration of necessary understandings of the currentless steady-state plasmas, which have high performance of temperature, density, confinement time and beta value extrapolatable to the reactor regime. This paper describes the necessary issues of major operations scenario especially concerned with the divertor functions, which realize the steady-state experiment in LHD.
