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.

Don’t get boxed in: Entergy CNO Kimberly Cook-Nelson shares her journey
Kimberly Cook-Nelson
For Kimberly Cook-Nelson, the path to the nuclear industry started with a couple of refrigerator boxes and cellophane paper. Her sixth-grade science project was inspired by her father, who worked at Seabrook power station in New Hampshire as a nuclear operator.
“I had two big refrigerator boxes I taped together. I cut the ‘primary operating system’ and the ‘secondary system’ out of them. Then I used different colored cellophane paper to show the pressurized water system versus the steam versus the cold cooling water,” Cook-Nelson said. “My dad got me those little replica pellets that I could pass out to people as they were going by at my science fair.”

Cryogenic adsorption is effective for the recovery of low-concentration hydrogen isotopes in bulk helium gases. In a fusion power plant, application of this process is foreseen for the recovery of tritium from the blanket sweep gas and cleanup of the helium discharge exhaust gas. The authors performed a screening test to find more suitable adsorbents for the recovery of hydrogen isotopes from the bulk helium gas at liquid nitrogen temperature. The screening test indicated that a natural mordenite adsorbent has a quite high adsorption capacity for hydrogen under a helium atmosphere. For the adsorption of deuterium, it was found that the natural mordenite adsorbent possesses a high adsorption capacity even at the lower pressure range of hydrogen and deuterium. The adsorption rates of hydrogen and deuterium were quantified by analyzing breakthrough curves obtained in experiments. Evaluated effective pore diffusivities of hydrogen isotopes in the mordenite adsorbents are considerably higher than those in MS5A adsorbents. Thus, it can be said that the natural mordenite adsorbents are suitable for adsorption of hydrogen isotopes from the viewpoint of adsorption rates, as well. The results suggest that mordenite-type adsorbents are promising for the recovery of low-concentration hydrogen isotopes from the helium bulk gas.
