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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

Experimental data are presented for the pressure drop of a flowing conducting fluid within a packed bed of spheres through a transverse magnetic field. Pertinent background information is presented about flows in porous media followed by relevant details of the experiment apparatus and equipment. The data are presented and discussed and then compared with the predictions from the previously developed analytical model. It is found that good agreement exists between the data when plotted in dimensionless form. As with the other equations for fluid flow in porous media, the analytical forms specify behavior to within an experimentally determined constant. A new constant, the Sanders constant, contained within the equation for the resistance ratio, is proposed. The experiment data are compared with the analytical model, and the best value of the Sanders constant is estimated.
