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.”

The average fuel pellet power ratio in a pellet-suspension core is investigated. This ratio relates the electric power required to sustain the pellet suspension to the electric power derivable from the fission process. For 2% enriched uranium in a suspending medium of helium gas, a power ratio >2 × 104 for a range of particle sizes is found. Comparable ratios of 1 × 104 for light water and 2 × 103 for liquid lead as suspending mediums are determined. For each fluid, the power ratio appears sufficiently favorable to warrant further investigation of such fission reactor cores
