Kinectrics, a division of BWX Technologies Inc. (NYSE: BWXT), and Burloak Technologies have successfully applied metal additive manufacturing for nuclear energy applications. The partnership, which began in 2021, aims to provide nuclear-grade components that address obsolescence issues in operational fleets and support emerging reactor technologies.
The collaboration involved manufacturing a hydraulic manifold using additive manufacturing techniques. The complex, pressure-retaining high-grade steel component was originally produced through conventional manufacturing methods. The part was designed and manufactured to meet nuclear service environment requirements and demonstrate a nuclear qualification path for Burloak’s metal AM process.
The initial focus targets high-obsolescence risk components in Canada’s CANDU fleet and other aging nuclear reactors. Both companies also see applications for additive manufacturing in Small Modular Reactors (SMRs) and advanced reactor designs. The technology’s ability to reduce part count, optimize fluid dynamics, and enable rapid prototyping aligns with next-generation nuclear technology goals.
“This program demonstrates that AM parts can be qualified for nuclear use when the process is controlled and validated to nuclear-grade standards. We’ve applied the same rigor we bring to traditionally manufactured components, ensuring that safety, performance, and traceability remain uncompromised,” said David Marttila, Senior Director of Nuclear Equipment Solutions at Kinectrics.
“Additive manufacturing enables on-demand production of replacement parts that are otherwise impossible to source. We’re not only solving for obsolescence — we’re working with Kinectrics to help develop the framework for using the Additive Manufacturing (AM) process in the Canadian nuclear industry, while creating new engineering options that meet and often exceed the performance of legacy manufacturing processes,” said Jason Ball, VP/GM at Burloak Technologies.
