je donne la parole \u00e0 un internaute :<\/p>\n

Effectivement, les r\u00e9serves d’uranium sont limit\u00e9es (environ 60 ans), mais :
-le prix du combustible intervient tr\u00e8s peut dans le cout de l’\u00e9lectricit\u00e9 nucl\u00e9aire (un doublement du prix de l’uranium entraine une augmentation de 5% du prix du kWh).
-l’approvisionnement est tr\u00e8s diversifi\u00e9, garant de stabilit\u00e9, contrairement aux combustibles fossiles.
-l’\u00e9lectricit\u00e9 nucl\u00e9aire est trois fois moins ch\u00e8re que l’\u00e9olienne, 10 fois moins ch\u00e8re que le photovolta\u00cfque.
-En utilisant des surg\u00e9n\u00e9rateurs (type Superph\u00e9nix) on passe \u00e0 4000 ans de r\u00e9serves (efficacit\u00e9 de l’uranium x 60) ou 16000 ans en utilisant le thorium<\/a>, 4 fois plus abondant que l’uranium.<\/p>\n

Pour respecter le protocole de Kyoto sans p\u00e9nurie d’\u00e9lectricit\u00e9, il faudra construire 2 reacteurs EPR par an en France en remplacement des 54 centrales actuelles qui arrivent en fin de vie.
Pour rappel en Europe, l’arret du nucl\u00e9aire \u00e9quivaudrait \u00e0 300 millions de tonnes de CO2 de plus par an, \u00e0 comparer \u00e0 la r\u00e9duction de 100 millions de tonnes par an necessaire au respect de Kyoto<\/a>.<\/p>\n

Ce point de vue est tout \u00e0 fait respectable mais me semble faux. Voila pourquoi.<\/p>\n

Selon l’institut IEER<\/a>, une \u00e9tude parue le 4\/05\/2006, la France peut :
– sortir du nucleaire en 40 ans et r\u00e9duire ses emissions de CO2 de 40 %. Cette sortie se ferait progressivement par la fermeture des centrales arrivant en fin de vie,
– on passerait quasi syst\u00e8matiquement \u00e0 la maison passive,
– le d\u00e9veloppement des energies solaires, eoliennes et hydraulique assurerait une partie de la production \u00e9lectrique, et les centrales au gaz, le reste.
– l’\u00e9olien, notamment maritime peut fournir 30 % de l’electricit\u00e9, au prix du nucleaire aujourd’hui.
– des normes s\u00e9v\u00e8res permettent de r\u00e9duire la consommation automobile \u00e0 2.4 litres au cent.<\/p>\n

Ce point de vue est celui de l’IEER. <\/p>\n

Je ne compte pas non plus les frais de d\u00e9mantelement de centrales (le co\u00fbt du d\u00e9mantelement de Brennilis est 5 fois plus \u00e9lev\u00e9 que pr\u00e9vu) et les frais de stockage pour… 100 000 ans ?
De plus, superph\u00e9nix \u00e9tait un nanard \u00e9ternellement en panne, et la technologie pour surg\u00e9n\u00e9rateur est loin d’\u00eatre pr\u00e9te…<\/p>\n
