In this episode of the "Innovation Hub" podcast from WGBH Radio:
The Three Mile Island disaster forced hundreds of thousands of people to evacuate their homes. It led to a complete rethinking of nuclear energy.

To find out exactly how this happens, Innovation Hub talked with Chris Clearfield, co-author of "Meltdown: Why Our Systems Fail and What We Can Do About It."
