Abstract

Núcleo para reactor nuclear que incluye: por lo menos dos tipos de conjuntos de combustible, incluyendo un primer tipo de conjuntos de combustible una multiplicidad de barras de combustible que se extienden conjuntamente de manera generalmente paralela y unas rejas dispuestas con una separación axial predeterminada para separar lateralmente dichas barras situadas en unas primeras alturas predeterminadas en el sentido axial del núcleo, e incluyendo un segundo tipo de conjuntos de combustible una multiplicidad de barras de combustible que se extienden conjuntamente de manera generalmente paralela y unas rejas dispuestas con una separación axial predeterminada para separar lateralmente dichas barras situadas en unas segundas alturas predeterminadas del núcleo, siendo por lo menos una de dichas segundas alturas predeterminadas en el sentido axial del núcleo, diferente de dichas primeras alturas predeterminadas en el sentido axial del núcleo, caracterizado porque unos conjuntos de combustible detransición están dispuestos entre dichos primero y segundo conjuntos de combustible, incluyendo dichos conjuntos de transición una multiplicidad de barras de combustible que se extienden conjuntamente de manera generalmente paralela y unas estructuras de reja de transición para separar lateralmente dichas barras dispuestas en cada una de dichas primera y segunda alturas predeterminadas del núcleo.
