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.

The neoclassical bootstrap current, parallel electrical resistivity and radial particle and heat transport properties are examined for a reference ITER low current plasma with elevated axial safety factor, q(0), and reverse shear, q′ < 0. The results are compared with two other reference cases at full current and differing plasma profiles. In each of the cases it is found that higher Z impurities are fairly robustly expelled from the core by ion temperature gradient screening, although the screening is weaker in the high q(0) plasma because of its lower collisionality. The bootstrap current is strongly enhanced in the high q(0) case as expected. Potato orbits do not significantly modify the results.
