EDF confirms cracks on 1.3 GW Paluel 2 reactor

Questioned by a parliamentary committee late on Thursday, Lewandowski said the French state-run firm had “recently” found traces of corrosion at its Blayais 4 (910 MW) and Paluel 2 reactors. He gave no further details.

Contacted by Montel, an EDF spokeswoman confirmed the firm had found cracks at the Paluel unit but refused to provide any other details such as when and where the corrosion was found or whether repairs were underway.

Having checked France’s newest reactors, which it said were most susceptible to corrosion, the firm was now probing older units, such as at Blayais and Paluel, he said, adding EDF knew it would also find cracks of “lesser importance” on those units.Corrosion was “still with us” and “would be until 2025” when the firm was due to complete its probe of France’s 56 reactors, he said.“Fortunately, we are now in the process of mastering it… Our construction sites are getting faster and faster, our ability to understand the phenomenon is now almost total.”

I find this line interesting: 'Fortunately, we are now in the process of mastering it… Our construction sites are getting faster and faster, our ability to understand the phenomenon is now almost total.' Meaning they don't fully/didn't understand this phenomenon? How does a faster construction site reduce cracks? Maybe it is poorly worded and means they are faster at fixing the cracks?
