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 fracture behavior of several tungsten based alloys was characterized by standard Charpy tests which have been performed up to 1100°C in vacuum. Due to their fabrication history (powder mixing, pressing, sintering, rolling) all materials had specific micro-structures which led to typical delamination fractures. The influence of notch machining method was also investigated. All results are discussed and assessed with respect to the optimization of future divertor component fabrication.
