Abstract

Un espaciador y un conjunto de combustible para un reactor nuclear de agua hirviendo. La invención se refiere a un espaciador (14) para un reactor nuclear de agua hirviendo. El espaciador (14) comprende una pluralidad de células (16) para retener o permitir que los elementos alargados (12) pasen a través de las células. Entre las células (16) existen una pluralidad de canales de flujo (18). El espaciador comprende al menos una pluralidad de miembros de desviación (22). El miembro de desviación comprende una paleta (24) que se extiende en una dirección desde una célula (16) dentro del canal de flujo vecino (18). La paleta está inclinada con respecto a un plano vertical (26) y es más ancha en su parte superior que en su parte inferior. La invención se refiere también a un conjunto de combustible para un reactor nuclear de agua hirviendo, que comprende un miembro de desviación con paleta de construcción similar.
