Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.
Meeting Spotlight

Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

Investigation of reactions between neptunium and soil samples representative of the saline area around the Gorleben salt dome (Federal Republic of Germany) was conducted to obtain an understanding of the transport mechanism of neptunium in saturated brine aquifers. Leaching of 237Np-doped glasses with brine under oxic conditions resulted in the release of soluble species of Np(V). Adsorption parameters obtained from the application of nonlinear sorption isotherms to static experiments were used to interpret the migration of neptunium through soil columns. The existence of two different adsorption sites reacting with neptunium at different rates was postulated. Retardation factors under oxic and anoxic conditions were measured. In anoxic environments such as those found in undisturbed repository horizons, more neptunium activity was fixed by the soil.
