Description

The brittleness of the graphite used for producing uranium tubes by gravity casting is monitored by acoustic test. Ancillary units, around a central data processing unit, also have a data processing function (micro-informatics) enabling the three following essential functions to be met: (1) control of the movement of integrating waves to five degrees of freedom, (2) control of the monitoring appliance and (3) pre-processing acquisition and presentation of the data. Mention is made of the facilities being used and of the progress of some research work

Abstract (French)

La fragilite du grahite utilise comme moules pour l'obtention de tubes d'uranium en coulee par gravite est controlee par essai acoustique. Autour d'une unite informatique centrale des unite annexes possedant egalement une fonction informatique (micro-informatique) permettant de repondre aux trois fonctions essentielles suivantes: - gestion et commande du deplacement des ondes traducteur suivant 5 degres de liberte, - gestion et commande de l'appareil de controle, - acquisition pre-traitement et presentation des informations. On fait etat d'installations en cours d'exploitation et de l'avancement de certains travaux de recherche
