AbstractAbstract
[en] This paper proposes a core design of fast reactor using mixed nitride fuel [(U,Pu)N], having small loss of reactivity and reaching a maximum thermal burn-up rate from 150 GWd/t, while being managed in single batch (renewal of the fuel in only one time for all the subassemblies of the core). This work was completed with aid of the studies of sensibilities of the fast reactors cores to principal parameters: general design of the core, volumetric percentages of the various mixture of materials composing the core, initial enrichments of the fuel. A detailed optimization study on the selected core was conducted complying with safety criteria taking into consideration of consequences of nitride material presence on fuel assembly design rules.

Ce memoire propose une conception de coeur de reacteur a neutrons rapides a combustible nitrure mixte (U,Pu)N de 3600 MWth, ayant une faible perte de reactivite et atteignant un taux de combustion thermique maximum de 150 GWj/t, tout en etant gere en frequence 1 (renouvellement du combustible en une seule fois pour tous les assemblages du coeur). Ce travail a ete realise a l'aide d'etudes de sensibilites de coeurs de reacteurs a neutrons rapides aux parametres: dessin general du coeur, pourcentages volumiques des principaux composants du coeur, enrichissements initiaux en Plutonium du combustible. Une etude d'optimisation fine sur le coeur degagee a ete menee, dans le respect des criteres de surete tenant compte des consequences du materiau nitrure sur le dimensionnement des assemblages.
