Les réacteurs nucléaires de génération III s'inscrivent dans la continuité des réacteurs à eau sous pression actuels, tout en présentant un certain nombre d'améliorations en terme de sûreté, de rendement et d'environnement.Parmi les caractéristiques de ces réacteurs, la taille importante du coeur et l'utilisation d'un réflecteur lourd se traduisent par une meilleure efficacité neutronique et une meilleure protection de la cuve.Du fait de leur grande taille, le risque de basculement de la nappe de puissance neutronique est exacerbé. Le basculement est donc un paramètre d'intérêt à prendre en compte dans les études de sûreté. Par ailleurs, le calcul de l'incertitude associée à la nappe de puissance neutronique est difficilement atteignable pa...
