The Impact of Additive Manufacturing on Nuclear Fuel Transport

In 2019, Orano Federal Services and the University of North Carolina at Charlotte explored the design of 3D-printed shock absorbers for containers used to transport spent nuclear fuel. However, the partners encountered several obstacles. Seven years later, the study has been revived, and some of those barriers now appear to have been overcome. So, is it worthwhile to 3D print these structures for the nuclear sector?

First, it is important to understand why there is a push to redesign these shock absorbers. Traditionally, they are made from balsa wood, redwood, or aluminum. Manufacturing costs can range from $250,000 to $1 million, as these are large components requiring significant amounts of raw material.

At first glance, additive manufacturing seems like a natural fit. By optimizing material usage, it could help reduce costs. That is indeed the objective. But as you might expect, the reality is more complex.
