Abstract

La barre grise comprend un tube de gainage à paroi mince (46) dont une première section longitudinale est disposée à l'intérieur du réseau des barres de combustible, tandis qu'une section longitudinale de ce tube se situe essentiellement à l'extérieur de ce réseau, lorsque la barre grise est introduite dans l'assemblage combustible, la première section formant un espace récepteur de pastilles (52),contenant une pile de pastilles annulaires (48), tandis que la seconde section longitudinale forme un espace creux (54) ne comportant pas de pastille et ne contenant qu'un ressort à boudin partiellement comprimé (50) qui assure la double fonction de retenir la pile des pastilles (48) dans l'espace (52) et d'assurer un support radial à la paroi de la seconde section longitudinale du tube.
