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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

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.
