Title (EN) APPARATUS AND METHOD FOR ULTRASONICALLY CLEANING IRRADIATED NUCLEAR FUEL ASSEMBLIES
(FR) APPAREIL ET PROCEDE DE NETTOYAGE PAR ULTRASONS D'ASSEMBLAGES COMBUSTIBLES NUCLEAIRES IRRADIES
Abstract: front page image
(EN)An apparatus (20) for cleaning an irradiated nuclear fuel assembly (70) includes a housing (24) adapted to engage a nuclear fuel assembly (70). A set of ultrasonic transducers (22) is positioned on the housing (24) to supply radially emanating omnidirectional ultrasonic energy to remove deposits from the nuclear fuel assembly (70).
(FR)L'invention porte sur un appareil (20) servant à nettoyer un assemblage combustible nucléaire (70) irradié. L'appareil comprend un boîtier (24) conçu pour entrer en prise avec un assemblage combustible nucléaire (70). Un ensemble de transducteurs ultrasonores est placé dans le boîtier (24) pour apporter une énergie ultrasonore omnidirectionnelle à émission radiale permettant d'éliminer les dépôts de l'assemblage combustible nucléaire (70).
