A device for cutting nuclear reactor fuel element sheaths

Description

The invention relates to a method for cutting fuel element cladding. A fuel element is moved past laser emitters in order that the laser radiations cut the fuel element clad along the whole length thereof. The two halves of the thus cut clads are then severed and the fuel is recuperated in a hopper. This can be applied to the extraction of the spent fuel from nuclear fuel elements, with a view to re-using the fuel after reprocessing

Abstract (French)

L'invention concerne une methode destinee a decouper l'enveloppe d'un element combustible nucleaire gaine. Un element combustible est deplace devant des emetteurs de rayon laser, de maniere que les rayons lasers decoupent l'enveloppe de l'element combustible sur toute sa longueur. Les moities d'enveloppe sont ensuite separees et le combustible est recupere dans une tremie. Ceci est applicable pour l'extraction combustible epuise des elements combustibles nucleaires, en vue d'une reutilisation de celui-ci apres traitement
