A look back at the Molten Salt Reactor Experiment

Promotional video from 1969 for the Molten Salt Reactor Experiment.

ORNL’s Molten Salt Reactor Experiment operated more than 13,000 hours during its four-year run in the mid- to late 1960s. A priority of long-serving lab director Alvin Weinberg, MSRE was noteworthy at least in part because it ran on fuel that circulated through the reactor rather than staying put in the core. 

ORNL create this 1969 promotional video for the Atomic Energy Commission, predecessor to the Department of Energy. For more information, check out Tim Gawne’s look back at MSRE.
