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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

Palladium and its alloys have been extensively studied because of their faculty to store reversibly hydrogen isotopes. Here, aging effects on pressure-composition isotherms of Pd(PtRh) solid solutions are investigated for tritium storage up to 5 years. The main changes observed are the decrease of the plateau pressures and the shift of the and branches towards greater stoichiometries, as it was already observed for pure palladium. In this study, we show that aging effects are greater on palladium substituted by platinum and/or rhodium than for pure palladium. These observations can be correlated to different evolutions of the structural and micro-structural properties of the solid solutions.
