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.

Nuclear thermal-hydraulics has a leading role in nuclear safety and in the viability of the nuclear industry. Over the past few years, there have been numerous innovations that are enabling the design of new and advanced reactor systems while providing increased margins of safety. NURETH-20 will highlight emerging technical innovations enabled by thermal-hydraulic research including passively cooled SMRs, advanced non-LWRs, “microreactors” cooled by heat pipes, and the use of artificial intelligence in data analysis. The opening plenary will feature several top innovators in the nuclear industry and provide an opportunity for attendees to hear how thermal-hydraulics makes it all possible.
