South Korean 3D-Printed Nuclear Power Plant Component Operates Continuously for 18 Months

Korea Hydro & Nuclear Power (KHNP) announced on August 26 that a nuclear power plant component manufactured using 3D printing technology has been in continuous operation for 18 months on a reactor unit. This marks the first time South Korea has completed long-term operational validation of a 3D-printed nuclear power plant component in actual service. The component is a multi-blade impeller used to cool the generator circuit breaker of a nuclear power plant. Traditional impellers typically consist of multiple blades mounted on a fixed plate, and the connection points between the fixed plate and blades are at risk of damage during long-term operation. KHNP completed the development of this impeller in 2024, switching to 3D printing to manufacture an integrated one-piece structure, thereby reducing weak connection points and improving component durability. Before being put into service, this 3D-printed impeller underwent...

Two U.S. National Laboratories Collaborate to Advance Arc-Based 3D Printing of Nuclear Pressure Vessels

Oak Ridge National Laboratory (ORNL) and Idaho National Laboratory (INL), both under the U.S. Department of Energy (DOE), announced a collaboration focused on advancing wire-arc 3D printing technology for industrial pressure vessels and qualification capabilities for critical nuclear components, aiming to expand the U.S. domestic supply chain. The two laboratories unveiled the collaboration during the Materials and Manufacturing Innovation Day event hosted at Oak Ridge National Laboratory on August 19. The event focused on topics such as advanced manufacturing, nuclear infrastructure, energy security, and domestic supply chains, and featured demonstrations and tours of the DOE Manufacturing Demonstration Facility (MDF). This facility is a large-scale research platform open to industry, primarily...

Rosatom masters 3D printing technology for copper and copper alloys

The additive manufacturing technology business division of Rosatom's Fuel Division recently announced that its experts have successfully manufactured products from copper and copper alloys using the RusMelt industrial 3D printer, marking progress in additive manufacturing with copper materials. According to reports, Rosatom had previously used selective laser melting (SLM) technology to produce metal 3D-printed equipment of various sizes, with commonly used materials including stainless steel, heat-resistant materials, and titanium. Due to copper's physical properties such as high thermal conductivity and high electrical conductivity, which also pose technical challenges for laser melting, its application in metal 3D printing has long been limited. The company's additive manufacturing technology center in Moscow...
