"This marks a new major step forward in the use of additive manufacturing for strategic applications in the nuclear industry, enabled thanks to our fruitful cooperation with Vattenfall," said Lionel Gaiffe, senior executive vice president of the Fuel Business Unit at Framatome. "We have already achieved promising results with 3D-printed fuel components in operating reactors, and we are committed to the qualification and industrialization of this revolutionary innovation in the generation of safe, reliable low-carbon energy for long term operations."
Installed at the base of fuel assemblies, the anti-debris filters play an essential role in protecting fuel rods by trapping debris from the reactor coolant. Conventionally manufactured through electro-chemical machining, the new 3D-printed versions simplify production and offer design enhancements for improved performance and safety.
"We welcome the development of new manufacturing methods that enable further increase of safety and performance in fuel designs," said Ove Nilsson, head of Vattenfall Nuclear Fuel.
Framatome has pioneered additive manufacturing in nuclear fuel since 2015, focusing on stainless steel and nickel-based alloys. Collaborating with global customers, the company introduced 3D-printed components in various reactors. Notably, in 2021, a 3D-printed stainless steel fuel assembly fastener was loaded into the Tennessee Valley Authority's Browns Ferry reactor in the U.S., and in 2022, 3D-printed fuel assembly components were used in Vattenfall's Forsmark reactor in Sweden.
