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 theoretical analysis concerning fission counter design and operation shows that an optimum ratio of cable impedance times detector capacitance over detector collection time exists for fission counters. Tests were performed to show the effects of gamma fields on fission chambers having different electrode spacings and various argon-nitrogen fill gas mixtures and pressures. Based on these tests, the FFTF in-vessel fission counters will have 0-080-in. plate spacing and be filled with 1.75 atm of Ar—7% N2. The electrode coating thickness will be 2 mg/cm2 of U3O8 (93% 235U enriched).
