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.

The nitrous oxide dosimeter will measure the absorbed dose in a mixed radiation field of gamma rays and thermal neutrons. The effect of the latter is due to the 14N(n,p)14C reaction (cross section 1.78 b). However, 15N2O has an extremely small cross section for thermal neutrons (0.02 mb) and thus measures only the gamma dose. Our studies using 14N2O - 15N2O mixtures show that 14N2O and 15N20 dosimeters can discriminate between ionizing radiation and thermal-neutron effects.
