Catastrophic nuclear accidents, like Chernobyl in 1986 or Fukushima No. 1 in 2011, are very rare, we’re incessantly told, and their probability of occurring infinitesimal. But when they do occur, they get costly. So costly that the French government, when it came up with cost estimates, kept them secret.
But now the report was leaked to the French magazine, Le Journal de Dimanche. Turns out, the upper end of the cost spectrum of an accident at a single reactor at the plant chosen for the study, the plant at Dampierre in the Department of Loiret in north-central France, would amount to over three times the country’s GDP. Financially, France would cease to exist as we know it.
Hence, the need to keep it secret. The study was done in 2007 by the Institute for Radiological Protection and Nuclear Safety (IRSN), a government agency under joint authority of the Ministry of Defense and the Ministry of Environment, Industry, Research, and Health. With over 1,700 employees, it’s France’s “public service expert in nuclear and radiation risks.” This isn’t some overambitious, publicity-hungry think tank.
