The Story of Nuclear Power: Coming this Fall from Closing the Gap
The award-winning Closing the Gap podcast is returning for a third season with a special series. It's a sweeping look at the past, present, and future of nuclear energy—one of the most promising, controversial, and misunderstood technologies of the modern age. We're traveling the world to trace the story of the atom—from ancient uranium deposits buried deep within the Earth to the newest reactor designs. The series will take listeners to Marie Curie's perfectly preserved laboratory in France, to a new nuclear waste repository in Finland designed to withstand an ice age, to a uranium boomtown in Utah that never quite went bust, and many other important places along the atomic trail.

Listen to Gwen on the Fissionary Podcast
Gwen, Jennifer, and Tony have spent this spring and summer traveling around reporting for an exciting new season of Closing the Gap that will tell the entire history of nuclear energy over 10 episodes-- from neutron star collisions to the most recent test reactors that just went critical by President Trump's July 4th deadline.
Those episodes will be ready in a few weeks but in the meantime, we discovered a sister show of sorts called Fissionary -- the podcast from the Nuclear Energy Institute (https://www.nei.org/). Their hosts Mary Carpenter and Jordan Houghton sit down with experts to uncover how nuclear technology is helping make our world a better place in some unexpected ways -- not just by helping us reach climate goals but also by influencing interior design and to help stop rhino poaching. They're in their sixth season now, which has them globe-trotting country by country to explore exciting nuclear developments all over the world. Sound familiar?
They interviewed our own Gwen Holdmann earlier this year about what nuclear power has to offer remote Arctic places. We're that episode with you now and if you like it you should look up more episodes of Fissionary. There are new episodes every Thursday and that should keep you occupied until Closing the Gap is back this fall.

Closing the Gap is hosted by Gwen Holdmann. Tony Williams is our producer and engineer. Jennifer Pemberton is our writer and editor. Music is from Blue Dot Sessions.

Coal-Powered Energy Research
In Fairbanks, four trainloads of coal arrive every day to power and heat the University of Alaska campus that's known for its cutting-edge research on integrating renewable energy technologies. Building a brand new coal-fired power plant in the 21st century was, to put it mildly, a controversial decision. But believe me when I tell you—we researched the heck out of it. Today on the show, I'll walk you through the backstory of how, when it came time to replace our campus power plant, we ticked through all our options and ended up with the newest coal plant in the country — and, some would argue, possibly the last.
