Démantellement:

Nucleaire

Il faut aussi remettre les chiffres avec l'inflation. Si le premier rapport de 2005 parle de 25G€, cela représente 30G€ 2019. Page 8 de ce rapport, on y voit :

Le démantèlement des centrales de première génération avait fait l'objet de provisions calculées comme celles des réacteurs actuellement en fonction. Or, le démantèlement en cours de la centrale de Brennilis a montré que le coût effectif était très supérieur au coût attendu pour le démantèlement des 58 réacteurs en activité.
