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.

Several neutronic calculations have been made for a specific hybrid blanket design in order to evaluate the capability that a fissile zone offers to improve the tritium or fissile fuel production and the energy gain of a fusion blanket. Studies with different fissile zone thickness show the usefulness of thin fissile zones to get high tritium breeding rates. Better total material (tritium plus fissile) production requires thicker fissile zones. Comparisons have been made between the materials neutronic damage expected in a pure fusion blanket and in a hybrid one, with greater energy to damage ratios obtained for the hybrid. Also, greater energy and damage rates are obtained for harder spectra (more 14 MeV neutrons in source) because of the higher potential of 14 MeV neutrons to produce fission in the hybrid blanket.
