Nuclear power plants’ reactor pressure vessels (RPVs)—the massive steel jars that hold a nuclear plant’s fissioning fuel—face incessant abuse from their radioactive contents. And they must be built with extra toughness to withstand pressure and temperature swings in the event of a loss-of-cooling accident like the one that occurred at Fukushima in 2011. As the triple meltdowns at Fukushima Daiichi showed, the next layer of defense against a nuclear release—the so-called containment vessels—can not be counted on to actually contain molten nuclear fuel that breaches the RPV.
Nuclear safety authorities have recently discovered weaknesses in several RPVs, and their contrasting responses suggest that the ultimate lessons from Fukushima are still sinking into international nuclear power culture—especially in the United States, where the Nuclear Regulatory Commission (NRC) is resisting calls to mandate tougher inspection of RPVs.

After months of negotiation, the French government has unveiled a long-awaited energy plan that is remarkably true to its election promises. The legislation’s cornerstone is the one-third reduction in the role of nuclear power that President François Hollande proposed on the campaign trail in 2012.
Under the plan, nuclear’s share of the nation’s power generation is to drop from 75 percent to 50 percent by 2025, as renewable energy’s role rises from 15 percent today to 40 percent to make up the difference. That is a dramatic statement for France, which is the world’s second largest generator of nuclear energy, after the United States. France has a globally-competitive nuclear industry led by state-owned utility Electricité de France (EDF) and nuclear technology and services giant Areva. Continue reading →
Government incentives for a pair of proposed nuclear reactors could cost U.K. taxpayers as much as £17.62 billion, thus exceeding the reactors’ projected cost. The EC figure is a preliminary estimate included in an initial report to London published on Friday by European Commission competition czars. The letter notifies the British government that—as we predicted in December—Brussels is launching a formal investigation to assess whether the subsidies violate European state aid rules.
The preliminary findings suggest that the U.K. and E.C. are on a collision source. As the Financial Times summed it up this weekend: “The severity of [the EC’s] initial concerns will cast a shadow over government hopes to win approval for the deal.”
Can a U.K. firm’s novel plant design defuse environmental concerns?
By Peter Fairley
Fifty years ago this July, Électricité de France began sealing off Normandy’s La Rance estuary from the sea. After three years of work, the world’s first large-scale tidal power plant was born. The station operates still, generating up to 240 megawatts of renewable power as the twice-daily tides force water in and out of the estuary through the hydroturbines seated within its 750-meter-long seawall. But the three years of construction were tideless, which devastated La Rance’s ecosystem, killing off nearly all of its marine flora and fauna; it would take another decade for the estuary to bounce back. Due in part to that ecological hangover, La Rance would remain the only tidal station of its scale for nearly five decades …

The Arctic is melting faster than predicted. Is now the time to shut down the low-carbon nuclear power plants in France — the 20th Century’s staunchest proponent of nuclear energy? Is natural gas produced via hydraulic fracturing or ‘fracking’ a gift that is buying time for a transition to renewable energy or a curse that reinforces fossil fuel dependence? Will carbon belching heavyweights such as the U.S. and China ever get serious about cleaning up their energy systems?
Such questions are top order in France, whose President kicked off a Grand Débat on energy this month Continue reading →
France’s government launched a working group this week to coordinate installation of a standardized national charging network for plug-in hybrid electric vehicles and battery-powered EVs. Many may be experience deja vu, so to speak, because this would apparently be the second such charging network the country has installed.
President Nicolas Sarkozy has set a goal of seeing 100,000-plus electric-mode vehicles on the road in 2012 and has offered French automakers bailout funding partially tied to development of EVs as summarized by Earth Times. But as French state minister for industry Luc Chatel told French business magazine Usine Nouvelle [French], “Their battery serves no point without the infrastructure to go with it.” Hence the working group struck last week, representing automakers, energy distributors such as state-owned nuclear utility EDF, municipalities and other players, which is to deliver a plan in June.
A who’s-who list of French corporate heavyweights angling for a piece of Sarkozy’s action leaves no doubt that government dollars impact industrial strategy. French state-owned power giant Electricité de France (EDF) is building the reactor at Flammanville that Sarkozy visited last week, using the third-generation EPR reactor designed by French nuclear technology firm Areva. But Sarkozy says a second EPR to be built further up the Normandy coast at Penly will unite EDF and France’s number two player in electricity, GDF Suez; Reuters reported today that French oil and gas firm Total also wants a “double-digit” stake in the project.
