Title (EN) METHOD FOR FABRICATING THIN CALIFORNIUM-CONTAINING RADIOACTIVE SOURCE WIRES
(FR) PROCÉDÉ DE FABRICATION DE CÂBLES FINS DE SOURCE RADIOACTIVE CONTENANT DU CALIFORNIUM
Abstract:
(EN) A method for reducing the cross-sectional diameter of a radioactive californium-containing cermet wire (17) while simultaneously improving the wire diameter to a more nearly circular cross section. A collet fixture (15) is used to reduce the wire diameter by contolled pressurization pulses while simultaneously improving the wire cross-sectional diameter. The method is especially suitable for use in hot cells for the production of optimized cermet brachytherapy sources that contain large amounts of radioactive californium-252.
(FR) La présente invention concerne un procédé destiné à réduire le diamètre de la coupe transversale d'un câble en cermet radioactif contenant du californium (17) tout en améliorant simultanément le diamètre du câble en une coupe transversale plus circulaire. Un dispositif de serrage (15) est utilisé de façon à réduire le diamètre du câble par des impulsions de pressurisation régulées tout en améliorant simultanément le diamètre de la coupe transversale du câble. Le procédé est particulièrement approprié pour une utilisation dans des cellules chaudes pour la production de sources optimisées de brachythérapie en cermet qui contiennent de grandes quantités de californium-252 radioactif.
