Shape Optimization of a Sodium Fast Reactor Core

چکیده
Résumé. On applique dans cet article une méthode d'optimisation géométrique dans le cadre de la conception d'un c÷ur de réacteur SFR dans le but de minimiser une contre réaction thermique connue sous le nom d'e et de vidange sodium. Lorsqu'une augmentation de température survient, ce type de réacteur peut être sujet à une forte augmentation de réactivité, un paramètre clé dans le contrôle de la réaction en chaîne en régime quasi-statique. On a recours à l'équation de di usion à un groupe puis on donne la généralisation du modèle d'optimisation pour l'équation de la di usion à deux groupes d'énergie. On présente ensuite quelques résultats numériques obtenus dans le cas de l'équation à un groupe d'énergie. On note que l'application de cette méthode conduit à des designs de coeur présentant des interfaces très régulières qui sont loin d'un design de coeur faisable sur le plan technologique. A cet e et, de nombreuses méthodes de pénalisation (comme celles rencontrées dans [2]) pourraient être employées.
