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.

A contact device of a new type - a sulfonic cation resin membrane (Nafio type) contact device for separating isotopes of hydrogen in the water-hydrogen system is represented. Its main feature is space separation of hydrogen and liquid water flows that allows using non-hydrophobic catalysts for realizing the process. Results of research on the isotope exchange efficiency carried out for model protium-deuterium system have been represented. Mass exchange efficiency dependencies on temperature (T = 333-413 K), pressure (P = 0.1-0.4 MPa), the hydrogen flow rate (GH2 = 20-120 NL/h) have been investigated for both hydrophobic and hydrophilic catalysts. High efficiency of membrane contact devices is noted in carrying out the chemical isotope exchange between hydrogen and water in the given range of conditions.
