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.

This paper presents a W mockup with an interlayer of diamond/Cu (DC) composite material. As a joining interlayer, DC composite material has high thermal conductivity and accommodative coefficient of thermal expansion. By adjusting the thickness of the DC layer and comparing different forms of armor, the optimal design is the brush armor mockup with a 1-mm-thickness DC layer. The thermal-structural behavior of this mockup was analyzed under the steady-state and transient heat flux by using ANSYS Workbench. The calculated temperature and stress indicate that the mockup can tolerate 10 MW/m2 steady-state heat flux at most. Then a transient heat flux (300 MW/m2 for 5 ms) is loaded on the top surface upon steady-state heat flux of 8 MW/m2. The surface temperature instantly rises to 2300°C, but a cracking trend is not shown at the loaded surface.
