Wolf Richter: 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.
It evaluated a range of disaster scenarios that might occur at the Dampierre plant. In the best-case scenario, costs came to €760 billion—more than a third of France's GDP. At the other end of the spectrum: €5.8 trillion! Over three times France's GDP. A devastating amount. So large that France could not possibly deal with it.
Yet, France gets 75% of its electricity from nuclear power. The entire nuclear sector is controlled by the state, which also owns 85% of EDF, the mega-utility that operates France's 58 active nuclear reactors spread over 20 plants. So, three weeks ago, the Institute released a more politically correct report for public consumption. It pegged the cost of an accident at €430 billion.
"There was no political smoothening, no pressure," claimed IRSN Director General Jacques Repussard, but he admitted, "it's difficult to publish these kinds of numbers." He said the original report with a price tag of €5.8 trillion was designed to counter the reports that EDF had fabricated, which "very seriously underestimated the costs of the incidents."
Both reports were authored by IRSN economist Patrick Momal, who struggled to explain away the differences. The new number, €430 billion, was based on a "median case" of radioactive releases, as was the case in Fukushima, he told the JDD, while the calculations of 2007 were based more on what happened at Chernobyl. But then he added that even the low end of the original report, the €760 billion, when updated with the impact on tourism and exports, would jump to €1 trillion.
"One trillion, that's what Fukushima will ultimately cost," Repussard said.
