Abstract
L'invention concerne une machine à cisailler des éléments combustibles nucléaires irradiés. Ladite machine comporte un ensemble de cisaillement amovible comprenant un support de la lame de cisaillement, un bloc de support des éléments combustibles et des éléments de serrage maintenant un élément combustible au contact du bloc de support, le support de la lame pouvant être mis en prise d'une façon amovible avec un vérin d'entraînement. Des dispositifs de manoeuvre des éléments de serrage peuvent être mis en prise d'une façon amovible avec ces derniers de manière à pouvoir enlever facilement l'ensemble de cisaillement de la machine. Application au cisaillement d'éléments tels que des éléments combustibles nucléaires irradiés.
