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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

Physical principles of recuperation (return) of charged particle energy in traps with rotating plasma are discussed. A specificity of these systems is that normally ion injection occurs due to ionization of neutral atoms in a volume with crossed fields. As this takes place, ions are accelerated in these fields in such way that the speed of cyclotron rotation equals the speed of azimuth drift of the plasma as a whole. A particle moves in the laboratory reference system along a cycloid, the ion energy being zero at the top point of the cycloid. This specificity of ion movement is used for recuperation of its energy when it leaves the trap. A two-stage recuperation scheme is considered. These stages are the ion's transition of the centrifugal barrier and collection of ions on the electrodes that form the radial electric field. The conditions for rather efficient realization of such recuperation are discussed.
