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.

Cross sections for the emission of protons, deuterons, and alpha particles from enriched targets of 63Cu and 65Cu bombarded with 9- and 11-MeV neutrons were measured. A charged-particle time-of-flight spectrometer capable of detecting particles with energies as low as 1 MeV was used to make these measurements. Cross sections and spectra are compared with statistical and preequilibrium model calculations. Level density parameters of various nuclei resulting from the best simultaneous fit to present and previous 15-MeV data are inferred.
