Flamanville nuclear plant explosion exposes crisis in French nuclear industry

An explosion in the machine shop of the Flamanville nuclear plant in Normandy, France on Thursday morning started a blaze that firefighters were able to bring under control only after midday. The increase in incidents in different plants in the last days, and the problems encountered in building the new EPR reactors, expose the growing crisis in the French nuclear industry.

Olivier Marmion, the spokesman for the local prefecture, told AFP: “It was a significant technical event but it was not a nuclear accident,” as the explosion occurred “outside the nuclear zone.” Five people are ill from smoke inhalation. According to initial information released by the Préfecture, the explosion, which was heard all around the site, was caused by a short-circuit of a ventilator underneath an alternator in the main machine room in the “non-nuclear” part of the site.

Reactor N°1 automatically cut itself off from the French Electricity Board’s (EDF) national grid following the incident, as did the Reactor N°2. The Nuclear Security Agency, which controls the security rules and procedures that all nuclear sites comply with, was not able to provide any further details on the incident other than those that had been relayed by the Préfecture.

For the moment, the extent of the damage caused by the fire has not been reported. According to the Association Get out of Nuclear (Sortir du Nucléaire), “the consequences of this event are not limited to the fire starting. Reactor N°1 had to undergo an emergency shutdown at 9:47 am. Not only does the residual heat still need to be evacuated but an emergency shutdown is never good for nuclear equipment, especially if it is already fragile… the Nuclear Security Agency (NSA) warns against brusque variations in temperature.”

1. Emergency shutdown is no big deal.

As long as operators respond right away and shut off steam flow as soon as a SCRAM (reactor shutdown) occurs.
