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.

Recent target injection and tracking experimental results with simulated room-temperature indirect-drive targets are briefly discussed. Extensions of those experiments for improved timing accuracy and for sabot removal from warm solid plastic spheres without significant accuracy degradation are presented. Recent direct-drive and indirect-drive target heating calculations are presented. Proposed experiments to test Deuterium-Tritium (DT) mechanical strength, improve target tracking accuracy at higher injection speeds, and measure effects of rapid target heating on survivability arc presented.
