There may have been no more fitting place to gather for a conversation about the future of nuclear energy than Colorado.

For the nuclear community, Colorado carries a special resonance. About an hour north of Denver stands Fort St. Vrain. Today, it is a garden-variety natural gas power plant. But there was a time it was an ambitious nuclear reactor—a high-temperature gas reactor with helium coolant and a uranium-thorium fuel cycle. It was ahead of its time in many ways and imperfect in execution, but unmistakably part of the long story of nuclear innovation in America.

Colorado is a state shaped by frontiers. We, too, are standing at a frontier, which brings me to this year’s conference theme: “Net Out, Power Up.” We chose this theme to reflect the complementary challenges facing two parts of our community. “Net Out” reflects fusion’s challenge: proving you can get more energy out than you put in. “Power Up” reflects fission’s challenge: scaling advanced nuclear technologies quickly enough to meet rising demand.

This year’s American Nuclear Society Annual Meeting was filled with great content, some of which was covered in the August issue of Nuclear News (beginning on p. 22). One of the meeting’s executive sessions, “Bringing Nuclear History Forward,” focused on advanced reactor (AR) history and was well attended. The United States—along with many countries around the world—is turning to nuclear to combat climate change. Part of this is funding new and innovative companies to create first-of-a-kind nuclear reactors to provide abundant and clean power. Looking at the current designs of interest to the community brings up interesting comparisons to the test and experimental reactors of the past. Test reactors like the Experimental Breeder Reactor-II (EBR-II), the Fast Flux Test Facility (FFTF), Peach Bottom, Fort St. Vrain, Germany’s AVR, and others now are more important than ever in providing insight, data, and operational lessons learned to develop the next generation of reactors.

In a May 15 piece, the editorial board of The Denver Gazette has weighed in on Colorado’s continuing controversy regarding how the state gets its electricity. While the current discourse in the state primarily pits fossil fuels against wind and solar, the board asks, “How about an energy source that generates almost limitless power, leaves no carbon footprint, and produces practically no emissions? It’s nuclear power—as green as you can get.”
