Thorium: The NASA Story

Editor's Take

Recovering a discarded chapter of atomic history, the film examines the molten salt reactor and the thorium fuel cycle once pursued and then shelved in the United States. It explains the underlying engineering and gives room to the argument that thorium could offer a safer path to nuclear power. The case it presents is an advocate's, and viewers should weigh the enthusiasm against the technical claims. Even so, it makes an unfamiliar and consequential episode of energy research accessible.

This documentary explores thorium and the molten salt reactor, a nuclear technology once developed and then largely abandoned in the United States. It explains how these reactors work, why some engineers believe thorium could power the world more safely and efficiently, and what happened to the early research. The film makes a technical subject approachable, weighing the promise and the practical obstacles with care. It is a detailed case for a road not taken in the history of nuclear energy.
