Controversy Over Diablo Canyon Nuclear Power Plant
Despite protests from citizens' groups concerned about safety, the Diablo Canyon nuclear power plant in California continued operations until its scheduled shutdown in 2025 due to economic reasons. The utility's decision to close the reactors highlighted the competition with renewable energy sources like wind and solar, emphasizing cost-efficiency over safety concerns.
Evolution of Nuclear Power in the US
The podcast delves into the turbulent history of nuclear power in the US, from rapid expansion in the 1970s to setbacks such as the Three Mile Island incident in 1979, which sparked safety improvements and regulatory changes leading to a decline in new plant construction. Despite the pivotal role of nuclear energy in California's power supply, debates persist about its contribution to decarbonization goals.
Impact and Future of Nuclear Energy
Discussions with nuclear expert Katherine Huff shed light on the importance of nuclear energy for achieving carbon emissions reduction targets but highlight the challenges of high costs and lengthy construction times for new reactors. The potential of small modular reactors (SMRs) emerges as a promising solution for scalable and sustainable nuclear energy, aiming to revitalize the industry and support clean energy transitions while addressing safety concerns and waste management.
The United States was once on track to be a world leader in nuclear power, building more than 100 plants in the 1970s and 1980s. But cost and safety concerns led to decades of decommissioning old plants and canceling plans to build new ones. Now, with clean energy production a top priority, there are signs of a revival. Reactors at the first new nuclear plant to be built in almost 30 years went online last year, and the Biden administration wants to triple the country’s nuclear capacity. Host Arielle Duhaime-Ross discusses the hurdles facing nuclear power, as well as a new vision for smaller, more adaptable reactors with Dr. Kathryn Huff, former assistant secretary for the Office of Nuclear Energy; historian and Pulitzer-Prize winning author Richard Rhodes; and the undergraduates – that’s right, undergraduates – who run their own nuclear reactor.
