“The degradation of concrete found in nuclear power plants has been underestimated” The director general of the Federal Agency for Nuclear Control (AFCN), Frank Hardeman, said Tuesday that the deterioration of concrete found in the non-nuclear parts of the two nuclear power plants had been underestimated. ” It has long been considered a concrete degradation with no impact on the structure, ” said Hardeman, who was questioned by the House’s sub-committee on nuclear safety. It is for this reason that the maintenance was initially “superficial”. The parts of nuclear power plants affected by concrete degradation problems concern standby safety systems. But they must be operational to ensure the operation of the plant against, for example, falling aircraft. The Doel 3 reactor has been affected but has become operational again after repairing moisture-impacted concrete, while Doel 4, Tihange 2 and Tihange 3 have been shut down for both planned overhaul and repair of their concretes.
