The Breakthrough Institute, a nuclear-friendly environmental research center based in Berkeley, Calif., has announced the launch of mobilization efforts for its Build Nuclear Now project, in partnership with the similarly minded groups Stand Up for Nuclear, Generation Atomic, Mothers for Nuclear, Nuclear New York, and Campaign for a Green Nuclear Deal.

The California Public Utilities Commission (CPUC) has voted to open a rulemaking to consider extending the lifetime of the 2,289-MW two-unit Diablo Canyon nuclear power plant. The plant, which turns 50 this year, is the only remaining operational nuclear power facility in California. It generates nearly 10 percent of the state’s electricity needs.

On a recent Freakonomics Radio podcast, host Stephen J. Dubner and his guests explored the topic of nuclear power. The episode, “Nuclear Power Isn’t Perfect. Is It Good Enough?” was teased on the podcast website with this thought: “Liberals endorse harm reduction when it comes to the opioid epidemic. Are they ready to take the same approach to climate change?”

There is still a chance for California’s last remaining nuclear power plant to stay open.

Last Friday, more than 50 nuclear advocates testified in support of the Diablo Canyon nuclear power plant at a California Energy Commission workshop. Many spoke of the need for California to shore up its electricity grid in the face of coming heat waves and power outages. Others emphasized that closing the plant, which generates 2.2 GW of electricity and currently provides 8.6 percent of the state’s total supply and about 15 percent of its low-carbon electricity, would be devastating to California’s emission-reduction goals.

In a recent opinion piece for the San Luis Obispo Tribune, Heather Hoff describes her conversion from nuclear energy skeptic to advocate and lays out the case for keeping the Diablo Canyon nuclear power plant open beyond its planned closure in 2025.

Hoff, who is an operations procedure writer at Diablo Canyon, tells how she spent years "excessively and sometimes annoyingly" investigating her concerns about the safety of nuclear after she was first hired at Diablo Canyon. She adds that she almost quit her job after the Fukushima accident until realizing that many concerns about that event were triggered by "fear of nuclear, rather than nuclear itself.”

Over the past couple of months, the nuclear community has participated in a grassroots effort to save the Diablo Canyon nuclear power plant from premature closure—and it appears to be having an effect. The growing support for keeping Diablo Canyon open is seen in editorials, an academic study from Stanford/MIT, and a grassroots rally held in December 2021 to show support for keeping Diablo Canyon operating.

An article published by The New Yorker profiles how Heather Hoff and Kristin Zaitz went from environmentalists who were skeptical, and even distrusting, of nuclear power to advocates for the much-maligned power source.
