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 total neutron cross section of 182Ta has been measured from 0.01 to 1000 eV using the MTR fast chopper. The observed total neutron cross section at 0.0253 eV is 8200 ± 600 b. Parameters of individual resonances below 30 eV and average parameters at higher energies give a resonance absorption integral of 943 ± 50 b and a neutron s-wave strength function of (1 ± 0.1) × 10−4 (eV) 1/2. The possible use of 182Ta as a neutron temperature monitor is discussed.
