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.

Judge temporarily blocks DOE’s move to slash university research funding
A group of universities led by the American Association of Universities (AAU) acted swiftly to oppose a policy action by the Department of Energy that would cut the funds it pays to universities for the indirect costs of research under DOE grants. The group filed suit Monday, April 14, challenging a what it termed a “flagrantly unlawful action” that could “devastate scientific research at America’s universities.”
By Wednesday, the U.S. District Court judge hearing the case issued a temporary restraining order effective nationwide, preventing the DOE from implementing the policy or terminating any existing grants.

Understanding of the tritium release process from ceramic breeders is of importance to establish a reliable tritium recovery concept for fusion reactors. Release behavior of tritium produced in the neutron-irradiated Li4SiO4 is investigated by the Thermal Desorption Spectroscopy (TDS). Thermal annealing behavior of the irradiation damages was also studied by Electron Spin Resonance (ESR) method.
These experimental results showed that the annealing process of the damages occurred in the almost same temperature range of tritium released from the neutron-irradiated Li4SiO4. This suggested that the thermal annealing processes of the damages were closely correlated with the tritium release process. It was also found that the thermal annealing consisted of two processes. The activation energies of the two processes were determined to be 0.5 eV and 0.96 eV, respectively.
