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 mathematical model of coatings of finite thickness is developed. Diffusion into a virgin region occurs for a specified time; diffusion out from the nonuniformly contaminated region then takes place for another specified time. The amount of contamination is given as a function of time and position, and the integrated contamination is given as a function of time. Curves are presented to make the model useful for the experimental determination of the diffusion coefficient.
