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.

Impurity ion radiation intensity has been studied in the GAMMA 10 plasma using both a collisional-radiative model (CR-model) and spectroscopic measurements. We have constructed absolutely calibrated soft X-ray, vacuum ultraviolet, ultraviolet and visible spectrographs for plasma diagnostics. Steady state CR-model calculation for carbon ions is used to obtain the carbon ion emissivities in the plasma. The CR-model calculation results of carbon ion radiation intensities are comparable to the results obtained by the impurity ion spectroscopy. Moreover, plasma rotation measurements are carried out in order to obtain radial electric potential profiles.
