Electrochemical process for the detection of flaws crossing a coating in PWR pressure vessels
Description
A NDT method is described for examination of defects of the welded stainless steel coating of the pressure vessel in PWR. In this process the electric potential between a reference electrode (or the coating itself) and an electrode moving near the coating surface is measured. A potential gradiant is developed around a crossing flaw and the signal of detection is created by the potential variation between the two electrodes
Abstract (French)
On decrit une methode de controle nondestructif de defauts du revetement inox depose par soudure de cuve de reacteurs PWR lors des arrets annuels. Le procede consiste a mesurer la difference de potentiel entre une electrode de reference (ou le revetement lui-meme) et une electrode qui se deplace pres de la surface du revetement. Au voisinage d'une fissure debouchante existe un gradient de potentiel et la variation de potentiel entre les deux electrodes constitue le signal de detectionAdditional details
