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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

To contribute to the confinement safety evaluation of radioactive materials in a glove box (GB) fire accident, combustion tests with polymethyl methacrylate (PMMA) and polycarbonate (PC) as typical panel materials for the GB have been conducted with a relatively large-scale apparatus. As important data for evaluating confinement safety, the release ratio and the particle size distribution of soot generated from burned materials as source term data for analyzing the migration behavior of soot particles were obtained. Furthermore, the effect of soot loading on the rise of the different pressure (ΔP) of the high efficiency particulate air (HEPA) filter ΔP was also investigated. The results showed that the release ratio of the soot generated from the burned PC was about seven times as large as PMMA and the relatively large particles of the soot from PC were also larger than PMMA. In addition, by considering the effect of the loading volume of the soot particles in the relatively low loading region of the soot, it was found that the behavior of the rise of ΔP accompanied with soot loading could be represented uniformly regardless of the kinds of combustion materials.
