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 streaming potential technique has been used to obtain the zeta potentials of ThO2 in HCl, HI, HNO3, and H2SO4 of various concentrations. The data are correlated with observed settling rates and tendency toward ThO2 colloid formation. Streaming current measurements were made on type 304 stainless steel samples. Evidence is presented to demonstrate the significance of the zeta potentials of the ThO2 and the stainless steel in the formation of thin films and thick cakes of ThO2 on the stainless steel.
