Description

The decree and the memorandum of 26/02/74 fix the periodic examination conditions for the primary circuit of nuclear stations. To satisfy these conditions with maximum efficiency the Commissariat has developed new nondestructive testing methods: focussed ultrasonics for examination of the pressure vessel during periodic inspection, acoustic emission when hydraulic trials are carried out, multi-frequency eddy currents for examination of the steam generator tubes. These various techniques and the equipment employed are described

Abstract (French)

L'arrete et la circulaire du 26/02/74 fixent les conditions d'examens periodiques du circuit primaire des centrales nucleaires. Pour satisfaire au mieux a ces conditions, le Commissariat a developpe des techniques nouvelles de controles non destructifs: ultrasons focalises pour l'examen de la cuve lors des inspections periodiques, emission acoustique lors des epreuves hydrauliques, courants de Foucault multifrequences pour l'examen des tubes des generateurs de vapeur. On decrit ces differentes techniques ainsi que les materiels qui les mettent en oeuvre
