Abstract

Cet embout inférieur (7) comprend : - des nez (39) d'orientation de l'écoulement de l'eau du réacteur le long des extrémités inférieures (19) des crayons de combustible (3), les nez (39) étant dis-posés en des nœuds du réseau sensiblement régulier des crayons de combustible (3), et - un dispositif anti-débris (43) délimitant des canaux (47) d'écoulement de l'eau. Au moins certains des canaux (47) d'écoulement de l'eau sont disposés en des nœuds du réseau sensiblement réguliers. Des nez d'orientation (39) sont dis-posés au moins en partie dans lesdits canaux (47) pour délimiter avec ces der-niers des passages d'eau (51), et au moins un passage d'eau (51) comprend une première section (S1) et une deuxième section (S2) qui sont décalées radialement l'une de l'autre par rapport au nœud correspondant du réseau pour former une chicane (56).
