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 methods of industrial ecology have been applied to the selection of a high-Z material for indirect-drive targets in the HYLIFE-II reactor. We quantify physical, chemical, and radiological impacts, rate the social-welfare impacts, and identify trends in the economic dimensions of the material selection. Early accident dose, the waste disposal rating, life-cycle volume, gamma dose rate, and resource availability are all considered. Four high-Z materials are considered: Ta, W, Hg, and Pb. A new activation module has been developed to accurately account for the complex activation scenarios of target materials. We explore a range of recycling scenarios and the results of these activation calculations are translated into the indices mentioned above. The recycling scenario can be modified to reduce accident hazards, disposal hazards, maintenance hazards, or fiscal expenditures, but different hazards or costs suggest different recycling scenarios are preferable. The IE methodology and examples of results are presented and areas for further study are identified.
