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.

In plasmas including fusion plasmas, various molecules exist in neutral and ionized forms and interact with each other as well as with electrons and photons. To properly understand and control the plasma, cross sections of these interactions are needed. Many of these interaction processes are initiated by electron scattering, and therefore an understanding of the electron scattering with atoms and molecules in plasma and their associated cross sections are very important to understanding of plasma. In this paper we evaluate the total electron scattering cross sections (TCSs) for eight plasma-relevant molecules - C2F6, CF3Cl, CF3I, C3F8, c-C4F8, CH4, C2H4, and C2H6 - both to present recommended TCSs and to demonstrate evaluation methods. We have reviewed data from the literature up to mid-2012 and the energy range of interest is up to and including 100 eV. TCSs for these common molecules, which are supposed to be in the best situation among the scattering cross sections, are far from satisfactory. More activities in measurements of cross sections are required.
