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.

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.

A study of the reactivity of ethylenediaminetetraacetic acid (EDTA), citric acid, and hydrazine for the dissolution of magnetite particles has allowed some steps of the different mechanisms to be identified. Two mechanisms are suggested: In acidic solutions, the chelating agents are adsorbed at the solid/solution interface followed by desorption of the complexed species FeHnL(n+1-4), where HnL is EDTA or citric acid, whereas in alkaline media, direct dissolution of the oxide particles takes place followed by complexation of the species Fe3+/Fe2+ in solution. The hydrazine apparently reduces the Fe3+ ions via a surface complexing reaction involving the ions, a reaction which is in competition with the protonation of the Fe3O4 crystal lattice. Finally, regardless of the type of oxide (Fe3O4, Fe2O3, FeOOH, CuO, or Cu2O) or the composition of the complexing solutions, suspensions of these particles are highly unstable with respect to agglomeration or settling out, more because of the high concentration of chelating agents than their chemical characteristics.
