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.

From South Korea to Belgium: Testing a high-density research reactor fuel
The Korea Atomic Energy Research Institute has developed a high-density uranium silicide fuel designed to replace high-enriched uranium in research reactors. Recent irradiation tests appear to be successful, KAERI reports, which means the fuel could be commercialized to continue a key global nuclear nonproliferation effort—converting research reactors to run on low-enriched uranium fuel.

Atmospheric pressure plasmas have many advantages for widespread applications since that are no necessary to use vacuum equipments. The work presented here is preliminary experimental results of hydrogen oxidation using an atmospheric pressure plasma. The experiment was done by a mixture gas included with a small amount of hydrogen and oxygen in an argon or a nitrogen plasma. As a result of mass spectrometry measurement, it has been found that hydrogen gas could be oxidized by the atmospheric pressure plasma. Moreover, dependence of the hydrogen conversion rate on the input power for discharge was confirmed. It has been also found that the hydrogen conversion rate in nitrogen plasma is higher than in argon one.
