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.

DOE opens pilot program to authorize test reactors outside national labs
Details of the plan to test new reactor concepts under the Department of Energy’s authority but outside national laboratory boundaries—first outlined in one of the four executive orders on nuclear energy released on May 23—were just released in a request for applications issued by the DOE.

Experimental and analytical studies on hydrogen-tritium isotope separation by a CECE process with a LPCE column have been carried out in order to apply it to the water detritiation system for fusion reactors. Kogel catalysts and Dixon gauze rings were mixed at a certain ratio and packed in the column in a random manner. Performance tests of tritium separation by the column of 1 m length and 2.5 cm I.D. were performed at 101 kPa and 343 K. The maximum value of the separation factor was 19200 when the flow rate of hydrogen gas was 5 L/min. The optimum value of catalyst packing ratio was obtained as 35 % by the analysis using the channeling stage model. The values of separation factors predicted by the model corresponded with measured ones very well.
