Abstract
One of nuclear energy’s biggest selling points is its claims of reliability. “Nuclear energy is the only large-scale power source that can be tapped in even the most extreme weather conditions, 24 hours a day, 7 days a week,” boasts the American energy company Constellation. “Nuclear power plants are very reliable, and can run for many months without interruption, providing large amounts of clean electricity, regardless of the time of day, the weather, or the season,” says the World Nuclear Association. At a public meeting in June, Keith Ammon, a pro-nuclear Republican member of the New Hampshire House of Representatives, echoed these claims: “Nuclear doesn’t care about the weather,” he said. “It just runs.”
Over the next few months, several countries in Europe had to shut down nuclear plants because of hot weather and drought—proving that nuclear power does, indeed, care about the weather. Coming at a time when demand for electricity was high, these countries were faced with an imminent failure of the electricity grid. Citizens and businesses in Hungary and Romania had to reduce their consumption. Ironically, it was solar power—often critiqued by nuclear boosters as unreliable—that provided additional electricity and staved off shortages in some countries. A further irony is that these heat waves are more likely and more severe because of climate change, which is often advanced as the reason to expand nuclear power in the first place.
