With the significant advances in additive manufacturing (AM), otherwise known as 3D printing, Orano Federal Services and the University of North Carolina at Charlotte recently re-examined the capabilities to print impact limiters for transportation casks used to ship spent nuclear fuel. Impact limiters protect transportation casks (sometimes also referred to as transportation overpacks) and their contents during an accident. Impact limiter designs must withstand testing based on a certain significance level of hypothetical accidents, including drops, crushing, fires, and immersion in water.
