Additively Manufactured Components Inserted into Operating Commercial Nuclear Reactor Core

During the Tennessee Valley Authority’s Browns Ferry refueling outage in April 2021, safety-related AM components were inserted into an operating commercial nuclear power plant’s reactor core.

The TCR program, partnered with the Tennessee Valley Authority and Framatome, designed and built four additively manufactured brackets, which were used in the installed fuel assemblies.

Additively manufactured components by ORNL headed for TVA nuclear reactor

The Transformational Challenge Reactor, or TCR, a microreactor built using 3D printing and other new advanced technologies, could be operational by 2024.

But the technology being used to develop the 14th reactor at the Department of Energy’s Oak Ridge National Laboratory may be tested in currently operating nuclear reactors as early as this spring.
