A SUBSIDIARY firm of EDF has responded to this morning’s explosion at a nuclear site in France.

An employee was killed and four other people were wounded - one seriously - following the explosion in the metal waste furnace room at the Centraco installation in Marcoule.

The site is maintained by EDF subsidiary firm Socodei, which confirmed no off-site release of radiological or chemical material had occurred.

Energy firm EDF hopes to build a third nuclear power station at Hinkley Point.

The explosion triggered a blaze in the furnace room that was brought under control at 1.06pm.

A spokesman for Socodei said: “The Nuclear Authority of Safety, the prefecture, the Local Commission of Information and the labour inspectorate have been advised.

“An investigation will be carried out in order to determine the precise causes of this tragic accident and the thoughts of everyone at Socodei are with those affected.

“It is the first time that such an event of this scale has occurred on site.”
