Rolling involves preheating a uranium or uranium alloy workpiece and passing it through a mill to reduce its thickness. This is useful in creating reactor fuel element foils and other products. Rolling mill operators possess a strong grasp of thickness-reduction limits, reheating intervals and temperatures, metallurgical phases, rolling speed and force, impurity influences and other techniques.
Forming of enriched uranium is done through a process called hydroforming, a way of shaping malleable metals. Y‑12 hydroform operators are highly skilled and trained machinists. Forming requires knowledge of friction on the workpiece, high-pressure application, tooling temperature and other factors. Y‑12 machinists effectively carry out forming operations without destroying the product or damaging the equipment.
