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 tandem mirror remains an attractive magnetic confinement geometry for fusion. The absence of toroidal curvature and relatively weak internal plasma parallel current gives the system strongly favorable stability and transport properties. Recent GAMMA-10 experiments demonstrate that sheared plasma rotation suppresses turbulent radial losses. Total energy confinement times calculated for the GAMMA-10 are found to be significantly larger than the corresponding empirical confinement times in toroidal devices. The tandem mirror appears to have a qualitatively different form of drift wave radial transport from that in toroidal devices.
