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 tritium breeders for a fusion reactor, Li2O, LiAlO2, and Li4SiO4, are compared on a thermochemical basis in respect to their response to protium purging. Two oxygen activity levels, established by H2O:H2 ratios of 100: 1 and 1:100 are considered at the temperatures 900 and 1300K. In terms of tritium release (all gaseous forms), LiAlO2 is better than Li2O and this in turn better than Li4SiO4. At 900K, Li2O and LiAlO2 release more tritium than at 1300K. Li4SiO4 releases more tritium at 1300K than at 900K.
