Abstract
A method for making a nuclear fuel channel is disclosed having a high degree of dimensional accuracy which uses the thermal expansion of a mandrel to precisely size the channel. An assembly of the mandrel and a channel preform is pulled through a die to die sink the preform into substantial surface-to-surface contact with the mandrel prior to the heating step.
