A method and apparatus are describod for sealing solid nuclear fuel bodies, e.g., a U rod, in a closely-fitting metal sheath with an internal atmosphere such as He. The apparatus comprises a draw-press with a pumping head arranged to be coupled to a sheath during the drawing of the sheath. Before the drawing operation, the Al sheath is evacuated by withdrawing air from a cavity at the inner end of the U rod via clearance spaces and grooves. He is introduced through a needle valve, and then the ram is operated to drive the loaded sheath through the die, trapping the He gas. (D.J.C.)
