White House taps Douglas Weaver for NRC role
The Trump White House has nominated seasoned nuclear regulatory expert Douglas Weaver for a commissioner seat on the Nuclear Regulatory Commission. If confirmed, Weaver would fill the seat vacated by NRC commissioner Annie Caputo, who resigned in July.
Weaver’s nomination was sent earlier today to the Senate Environment and Public Works Committee. If confirmed, he would finish the remainder of Caputo’s term, which expires June 30, 2026.

A total of 22 gamma-ray transitions were measured from (n,n′γ) reactions on the four even-even nickel isotopes, 58,60,62,64Ni. Absolute gamma-ray production excitation functions at 125 deg were extracted for these transitions from their thresholds up to neutron energies of 4 MeV. Inelastic neutron scattering cross sections for 19 levels were inferred from the gamma-ray production data and compared to the Evaluated Nuclear Data File (ENDF/B-IV, MAT 1190). Cross-section agreement for the first excited 2+ states in these four isotopes is generally good, but excitation functions associated with many of the higher excited states in nickel are in strong disagreement with the file.
