Abstract

Abstract Translated from French Cette machine d'examen (8) d'un assemblage combustible (6) de réacteur nucléaire est du genre de celles qui comprennent un support (28) sur lequel l'assemblage (16) à examiner est positionné, une source émettrice d'ondes (64), dirigée vers l'assemblage (6) à examiner, des moyens d'examen de l'assemblage (40, 64) qui reçoivent les ondes émises par ladite source (64) et qui ont été réfléchies par l'assemblage. Les moyens d'examen comportent un axe, cet axe étant dirigé vers un miroir (62) étant incliné de telle manière qu'il renvoie les ondes réfléchies par l'assemblage (6) vers les moyens d'examen (40, 64), une protection (66) contre le rayonnement émis par l'assemblage (6) étant disposée entre ce dernier et les moyens d'examen (40, 64). This examination machine (8) of a fuel assembly (6) of a nuclear reactor is of the type which includes a support (28) on which the assembly (16) to be examined is positioned, a source emitting waves. (64), directed towards the assembly (6) to be examined, means for examining the assembly (40, 64) which receive the waves emitted by said source (64) and which have been reflected by the assembly. The examination means comprise an axis, this axis being directed towards a mirror (62) being inclined in such a way that it returns the waves reflected by the assembly (6) towards the examination means (40, 64), a protection (66) against the radiation emitted by the assembly (6) being disposed between the latter and the examination means (40, 64).
