Abstract
A method and apparatus for reducing the volume of a cylindrical tube for disposal by crushing flat and then shearing into small coupons. Shearing is accomplished by opposed dies having a checkerboard grid of cutting edges. The resulting coupons are preferably substantially square in shape. The invention is particularly useful for reducing the storage volume of irradiated radioactive pressure tubes from a nuclear reactor.
