Abstract

Rejilla separadora mejorada para conjuntos de combustible nuclear que presenta un haz de varillas que se extienden longitudinalmente en general paralelas entre sí, caracterizada esencialmente por comprender: medios de separación para mantener las varillas en general separadas paralelamente, cuyos medios de separación comprenden, al menos, una tira de rejilla exterior que circunscribe toda la periferia del haz de varillas, cuya tira de rejilla exterior tiene un primer borde que define el límite de dicha tira en una dirección longitudinal y un segundo borde que define el límite de dicha tira en la otra dirección longitudinal, cuya tira de rejilla exterior presenta, al menos, una banda formada en ella paralela a la dirección longitudinal; una pluralidad de escudos de esquina entrantes que truncan una pluralidad de esquinas formadas por dicha banda, dicho primer borde y dicho segundo borde.
