IRRADIATION TESTS ON SEALS WITH AN ULTRASONIC SIGNATURE AND INTEGRATED TRANSDUCERS
Some seals with ultrasonic signature and integrated transducers were studied and developed in the Non Destructive Testing Laboratories of the JRC Ispra. Some applications in the frame of the "SAFEGUARDS" programme have shown that these seals may be submitted to a maximum flux of 10**2 - 10**3 rad/hour, with an integrated dose up to 10**7 rad. Three "CANDU" seals and four cells containing special transducers have been irradiated in the "TRITON" reactor at the CEA Fontenay-aux-Roses. A daily control of the have been taken every week and also when modification of the signal were noted. So, it has been possible to determine the origins of the instabilities of the destruction of the identities and to define the interaction between the gamma flux and the seals components.
