Abstract

Barre remplie de modérateur pour assemblage de combustible nucléaire, comprenant un corps tubulaire (50) dont les extrémités opposées sont scellées par des bouchons extremes (52, 54) et formant une chambre (42) qui contient un modérateur liquide, tel que de l'eau légère, l'un des bouchons extremes étant conformé en un puits à hydrure (48), tandis qu'une matière (46) formant piège à hydrogène est prévue au voisinage de l'autre bouchon extreme.
