Documents reveal major safety flaws at EPR and other French reactors

On Monday 27 September, the French Nuclear Phase out Network "Sortir du nucléaire" received internal EDF documents, showing that the design and manufacture of the vessel closure head for the EPR in Flamanville could lead to a Chernobyl-type accident. Worse still, according to a memo written by the Head of nuclear fuel from EDF in 2001 (1), a Chernobyl-type accident is possible on all French nuclear reactors. The EPR is also concerned. Several EDF documents show that the number of welds and the type of steel used in some parts of the reactor vessel at Flamanville EPR may cause leaks. EDF considers that the leaks may, in turn, degenerate into a Chernobyl-type accident. This type of steel and welds are part of the emergency shutdown system of the EPR and cover 89 points of entry into the reactor vessel.  Read the full press release.

Calvert Cliffs EPR looks in doubt as EDF and Constellation feud

The so-called nuclear "Renaissance" is starting to look less like a marble David and more like a collapsing cooling tower as U.S. utility, Constellation, becomes the next to run for the exits. According to a Bloomberg article, Constellation and French partner, EDF, are in frantic talks to try to save their joint U.S. venture - a third reactor at the Calvert Cliffs nuclear power plant site on the shores of  the Chesapeake Bay.

New French reactor in doubt as GDF Suez pulls out

GDF Suez, the second largest utility in France, has withdrawn from the newest nuclear reactor project there. GDF Suez, 35% state-owned, was a partner with the leading - and fully government-owned - French utility, EDF in the new reactor construction project planned at Penly on the north coast. But despite shouldering 25% of the financing, Suez was prevented by EDF from operating the reactor, a role reserved for EDF. Suez depended on operating experience to market its expertise overseas. The withdrawal marks another blow to the French EPR reactor project already suffering from huge delays and cost over-runs at its French and Finnish construction sites.

French "nuclear miracle" plagued by fast-rising reactor costs and "crowding out" of renewables

A new study by Dr. Mark Cooper of Vermont Law School, released today, warns "it is highly unlikely that the problems of the nuclear industry will be solved by an infusion of federal loan guarantees and other subsidies to get the first plants in a new building cycle completed. U.S. policymakers should resist efforts to force the government into making large loans on terms that put taxpayers at risk in order to ‘save' a project or an industry that may not be salvageable." The press release contains a link to the executive summary and the full report. Steven Thomas of Greenwich University in London, expert on Electricite de France and Areva economic woes, joined Dr. Cooper for the press conference, a full audio recording of which can be found at www.nuclearbailout.org after 6 p.m. today.

More problems plague French reactor

Electricite de France, currently constructing the Areva EPR reactor at Flamanville in Normandy has admitted that it has encountered yet another technical problem. Faults in welds of the reactor containment were found during an inspection in July by the Autorite de Surete Nucleaire. The same site had experienced delays due to technical problems with the concrete foundations and other issues that have marred progress and damaged the Areva claim that the EPR is a breakthrough in reactor design. The problems mirror the technical set-backs and cost-overrruns at Areva's EPR construction site in Finland which is now considered to be at least three years behind schedule.
