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.
Meeting Spotlight

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.”

Heat of transports Q* of hydrogen isotopes in the α-phase of Zr have been measured in temperature regions from 623K to 673K for H and from 523K to 623K for T by analysing the redistribution process under a thermal gradient. An isotope mass dependence of Q* has not been unequivocally established though a tendency that Q*(H)>Q*(T) has been observed. These data have been discussed on the basis of the biased-jump diffusion model, and a large negative bias effect has been pointed out as characteristics of Q* of hydrogen isotopes in group-IV metals in comparison with the case of group-V metals.
