An unconventional approach to nuclear energy production just got one step closer to reality. A prototype reactor canister just arrived at its installation site in Kansas, where it will soon be part of a proof of concept for a first-of-its-kind underground small modular reactor system. California-based startup Deep Fission believes that by burying a small nuclear reactor deep under the ground, they can make nuclear energy cheaper and safer at a time when round-the-clock carbon-free energy is needed more than ever before. “The prototype has…
