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.

Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

Rotation of a Field-Reversed Configuration (FRC) plasma due to a resistive flux decay is numerically studied. When the anomaly factor is 10, the flux lifetime is found to be about 60 sec in a case that the external magnetic field is O.4 T and the wall radius is 0.17 m. Single-particle motions in a quasi-steady resistively decaying FRC equilibrium are calculated, and a local flow velocity is estimated by a particle-in-cell method. An electric acceleration of a betatron particle near the field-null is shown; this can cause a plasma rotation. From a comparison of the toroidal ion flow velocity profile between with and without the flux decay, it is found that the ion rotation begins at the field-null.
