Korea Hydro & Nuclear Power (KHNP) successfully operated a 3D-printed nuclear component for 18 months without defects, marking the first long-term demonstration of such a component in Korea. The multi-blade impeller, used to cool the generator circuit breaker at Saeul Unit 1, was developed using additive manufacturing technology in 2024.
By printing the fixed plate and blades as a single integrated component, KHNP eliminated potential weak spots that arise from assembly joints in conventional products. The impeller underwent rigorous verification procedures before installation in January 2025. It operated continuously until July 2026 without defects, proving its ability to withstand long-term operation in a nuclear power plant environment.
This achievement highlights the potential of 3D-printing technology to enhance the durability and performance of specialized nuclear components, drawing attention from industry observers. KHNP plans to expand the use of 3D-printed components to other nuclear power plants and explore its application for next-generation nuclear technologies, such as small modular reactors.
