The Fessenheim nuclear power plant in France has seen an upgrade completed that will allow the facility to continue to remain open and producing electricity.

The work involved an upgrade to the the concrete basemat under EDF’s (Euronext: EDF) Fessenheim 1, which had it not been completed by the 30th June deadline, would have seen the reactor close for safety reasons.

The upgrade, which involved increasing resistance of the basemat to the potential effects of molten fuel, means the plant now meets the criteria laid down by French energy regulators following EU stress tests two years ago.

Fessenheim’s two 880 MWe pressurized water reactors have been in operation since 1977 and 1978 respectively. French reactors are required to undergo an in-depth regulatory review every ten years.
