Title (EN) SHEAR MACHINES
(FR) MACHINES A CISAILLER
Abstract:
(EN) A shear machine for irradiated nuclear fuel elements has a replaceable shear assembly (1) comprising a fuel element support block (4), a shear blade support (16) and a clamp assembly (15) which hold the fuel element to be sheared in contact with the support block. A first clamp member (7) contacts the fuel element remote from the shear blade and a second clamp member (8) contacts the fuel element adjacent the shear blade and is advanced towards the support block during shearing to compensate for any compression of the fuel element caused by the shear blade (2).
(FR) Une machine a cisailler pour elements de combustible nucleaire irradie possede un assemblage de cisaillement remplacable (1) comprenant un bloc support d"elements de combustible (4), un support de lame de cisaillement (16) et un assemblage de serrage (15) qui tient l"element de combustible a cisailler en contact avec le bloc support. Un premier organe de serrage (7), en contact avec l"element de combustible, maintient ce dernier eloigne de la lame de cisaillement et un deuxieme organe de serrage (8) est en contact avec l"element de combustible le maintenant adjacent a la lame de cisaillement et avance vers le bloc support pendant le cisaillement pour compenser toute compression de l"element de combustible due a la lame de cisaillement.
