Looking Back At The Nuclear Power Plant, Fort St. Vrain

Governor Jared Polis has pledged to power Colorado on 100% renewable energy. And, the state's largest utility, Xcel Energy, has set a goal of providing only carbon-free power. That leaves the door open to a number of non-renewable, yet carbon-free energy sources, including nuclear power.

If that were to happen, it wouldn’t be Colorado’s first foray into atomic energy. The state once had a unique nuclear plant with a pioneering design. Thirty years ago, it was powered down for the last time. Producer Paul Karolyi explains why.
