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.

An alpha-particle gas densitometer is described with an instrument response that can be tailored to given specifications by shaping the energy distribution of the radioactive alpha source. Relations are derived to establish the connection between a specified densitometer response and the corresponding source distribution. Shaped sources can be constructed by mounting contoured baffles on alpha sources. The operation of the densitometer is demonstrated experimentally for a linear and a logarithmic instrument response to air density variations.
