Why Nuclear Fusion Reactors Won't Blow Up

Nuclear fusion holds promise as a safe, clean source of energy to power our future. We’re probably decades away from using fusion as a viable source of energy, but some experimental reactors are already online.

YouTuber Tom Scott took a visit, to discover the science (and worryingly simple) safety precautions that make fusion less dangerous than its better-known cousin. As it turns out, running an experiment on a fusion reactor doesn’t require much input from humans—just some well thought-out protocols, and a good sound system.
