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.”

Earlier experiments suggested that large differences in heat release between the two sides of a palladium electrode coated with gold on one side and manganese oxide on the other cause observed electrode deformation with high-pressure D2 gas loading in an electrolysis-like cell Similar experiments were repeated using heavy water electrolysis. Palladium/titanium coatings on one side and gold coating on the other were made for the preparation of the palladium electrodes. Biaxial bending, partial discoloration, and microcracks of palladium electrodes were observed after 18 days of electrolysis. Analysis of the deformed palladium cathodes was performed. It was discovered that to convert this configuration to a practical energy-producing cell, a coating technique must be found to reduce outward diffusion of deuterium, i.e., to maintain a high D/Pd ratio over longer periods of time.
