Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Fermilab center renamed after late particle physicist Helen Edwards
Fermi National Accelerator Laboratory’s Integrated Engineering Research Center, which officially opened in January 2024, is now known as the Helen Edwards Engineering Center. The name was changed to honor the late particle physicist who led the design, construction, commissioning, and operation of the lab’s Tevatron accelerator and was part of the Water Resources Development Act signed by President Biden in December 2024, according to a Fermilab press release.

Fusion technology as a possible and promising alternative energy source for the future is intensively investigated at Karlsruhe Institute of Technology (KIT). The KIT divertor design for the future DEMO fusion power plant is based on a modular concept of He-cooling finger units. More than 250,000 single parts are needed for the whole divertor system, where the most promising divertor material, tungsten, must withstand steady-state heat loads of up to 10 MW/m2.Powder injection molding (PIM) as a mass-oriented manufacturing method of parts with high near-net-shape precision has been adapted and developed at KIT for producing tungsten parts, which provides a cost-saving alternative compared to conventional machining. While manufactured tungsten parts are normally composed of only one material, two-component PIM applied in this work allows the joining of two different materials, e.g., tungsten with a tungsten alloy, without brazing.The complete technological process of two-component tungsten PIM of samples, including the subsequent heat-treatment process, is outlined. Characterization results of the finished samples, e.g., microstructure, hardness, density, and joining zone quality, are discussed.
