The Tennessee Valley Authority will load four new 3D-printed fuel assembly brackets next spring at its Browns Ferry nuclear power plant, in Athens, Alabama. The brackets will be the first of their kind loaded into a commercial reactor, according to the Department of Energy.

The components, also called channel fasteners, were manufactured at Oak Ridge National Laboratory, in Tennessee, in a joint project with TVA and its fuel supplier, Framatome, as part of the lab’s Transformational Challenge Reactor program. The program is designed to introduce new manufacturing techniques and approaches to industry partners in order to speed up the deployment of nuclear systems.
