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.

Electron Cyclotron Resonance Heating by injection of two microwave beams with different k// has been investigated in the GAMMA 10 tandem mirror. In experiments, measurements of an effective temperature of an end loss electron flux and an end plate potential indicate that, for the same total incident power, heating efficiency of two beam heating is a little worse than that for one beam heating. Numerical analysis of electron energy gain by two beam ECRH gives the result of a little worse heating efficiency agreeing with that of the measurements, and the result is able to be explained as spatially sequential heating due to Doppler-shifted resonance gap for two beam heating.
