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.

Combinations of dialkylphosphoric acids (HA) and neutral organophosphorus reagents (B) have for some time been known to produce enhanced (synergistic) extraction of and other actinide ions. This effect may be attributed to the formation of a mixed complex—either a substitution product MO2A3HB or an addition product MO2A4H2B resulting from the reaction of B with the extraction complex MO2A4H2 normally formed with HA alone. Available extraction data, when analyzed in terms of the competing hydrogen-bonding interactions between HA and B, appear more consistent with an addition product MO2A4H2B. The stability of this mixed complex as a function of the neutral organophosphate used and as a function of the diluent used is consistent with hydrogen bonding or solvation of MO2A4H2 by B. The much stronger and more general synergism found in systems wherein HA is replaced by the β-diketone, Thenoyltrifluoroacetone (HY) may be attributed to the relatively weaker competing interaction between HY and B and to the less coordinatively saturated extraction complexes formed by HY alone.
