Deep Fission raises $30M in financing
Since the Department of Energy kicked off a 10-company race with its Nuclear Reactor Pilot Program to bring test reactors on line by July 4, 2026, the industry has been waiting for new headlines proclaiming progress. Aalo Atomics broke ahead of the pack first by announcing last week that it had broken ground on its 50-MWe Aalo-X at Idaho National Laboratory.

A previously described experimental method of determining initial conversion ratios in reactor lattices has been improved. Measurements have been made on D2O-cooled, 19-element UO2, heavy-water lattices at pitches of 18, 21, 24, 28, and 36 cm. The initial conversion ratios obtained were 0.9547 ± 0.0086, 0.8578 ± 0.077, 0.7671 ± 0.0069, 0.7416 ± 0.0067, and 0.6853 ± 0.0062 and the resonance escape probabilities derived are 0.8226, 0.8656, 0.9104, 0.9228, and 0.9511, respectively. The fast fission factors obtained for the 18, 24, 28, and 36 cm lattice pitches were 1.0283, 1.0265, 1.0253, and 1.0247.
