Wild Thing

A faulty reactor overheats, melting through its containment unit and poisoning a nearby town with radioactive gas. A spacecraft pushes further into deep space, exploring new galaxies, powered by a small nuclear reactor. An ordinary scientist is struck by cosmic rays—and finds he has new powers. Fiction? Or fact? Or a little of both? Stories of nuclear peril and promise permeate American media, and especially comic books. A preview of a special bonus episode, in which we explore atomic comics and why nuclear ideas captured artists’ imaginations.

What were the long-term effects of the SL-1 explosion? Nuclear power is a shrinking part of America’s energy picture; accidents and fear have tarnished it, and the old reactor fleet is reaching its end. Yet nuclear energy could provide a bulwark against the looming threat of climate change. Is it something we can make work for us, in spite of ourselves? Are the costs worth it in the long run? Sixty years on, what do we know—and are we better prepared?

Incidents like Chernobyl and Fukushima are often what comes to mind when we think about nuclear energy. Thankfully, events like these actually very rare. So does that mean the risks we associate with atomic power are as bad as we think? How good are we at actually assessing those risks? And can we make things even less risky by removing humans from the equation? That’s how some next generation projects hope to make nuclear energy safer.
