C’est faux, mon pauvre dede !

http://en.wikipedia.org/wiki/Shutdown_%28nuclear_reactor%29

"shutdown refers to the state of the reactor when it is subcritical by at least a margin defined in the reactor’s technical specifications. Further requirements for being shut down may include having the reactor control key be secured and having no fuel movements or control systems maintenance in progress."

Ces conditions ne peuvent pas etre reunies a Fukushima.
On ne peut calculer la marge de sous-criticite a Fuku, comme on ne peut plus utiliser un quelconque systeme de securite sur des barres de controle, ces barres de controle etant tout bonnement fondues.
