Framatome's breakthrough 3D-printed nuclear fuel elements successfully completed the first cycle of irradiation in operating conditions. As part of a qualification project, these experimental stainless steel and nickel-based alloy components were installed at the Gosgen Nuclear Power Plant in Switzerland in 2019 for a five-cycle program. These components will be further examined to confirm behavior in real operating conditions.

"We are very interested in the innovation and opportunities offered by additive manufacturing of nuclear fuel," said Dr. Gaetan Girardin, head of Nuclear Technology at the Gosgen Nuclear Power Plant. "We continually explore technological advancements that drive the efficiencies and performance of our plants. This is why we decided to be the first to introduce these experimental components in our power reactor."

Additive manufacturing accelerates Framatome's product development and streamlines the manufacturing process to bring high-quality products to market quickly. The innovative technique manufactures metal parts with complex geometries that would be unattainable with traditional processes. It also offers customizations and significant improvements in the performance of manufactured components.

"The evidence-based findings from our research and qualification project, conducted on components produced using additive manufacturing, reinforce our confidence in future uses of this technology," said Lionel Gaiffe, senior executive vice president of the Fuel Business Unit at Framatome. "Today, we embark upon the certification of components and additive manufacturing for our nuclear fuel assembly components."

Framatome will launch additive manufacturing for its industrial manufacturing of fuel assembly components for pressurized water, boiling water and VVER reactors. The technique is also regularly used for other nuclear fuel applications such as rapid prototyping, and manufacturing of test components and fuel production line tools, in-reactor fuel inspection and repair services tools, research reactor fuel assemblies, and uranium metal medical targets.

The additive manufacturing project was initiated in 2015 at Framatome's prototyping laboratory in Erlangen, Germany. It focuses on additive manufacturing for stainless steel and nickel-based alloy fuel assembly components.

The project involves Framatome fuel experts from France, Germany and the U.S., in close collaboration with customers worldwide. The project is also supported by the European Union and U.S. Department of Energy programs and relies on international laboratories and companies recognized for scientific advances in additive manufacturing.

Belarus launches nuclear plant despite Baltic outcry
Minsk (AFP) Nov 3, 2020
Belarus on Tuesday launched its controversial Russia-built nuclear power station despite safety concerns from neighbouring Baltic states three decades after the Chernobyl nuclear disaster. A string of incidents during construction of the nuclear power station has raised questions over its safety among EU countries, particularly neighbouring Lithuania. The launch comes as Belarus strongman leader Alexander Lukashenko faces historic protests over his claim to victory in August presidential polls ... read more
