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 ARIES study investigates the potential of tokamaks as fusion power reactors and focuses on improving the economic and safety features of fusion by integrating the environmental constraints into the design from the beginning. The ARIES-II and ARIES-IV designs incorporate advanced physics and technologies that would be available over the next 5–20 years. The two designs have the same plasma physics but different fusion-power-core designs.1 ARIES-II uses liquid Li as a coolant/breeder with V alloy structure while ARIES-IV employs solid breeder with He coolant and SiC/SiC composite structure. Low activation materials were utilized in the design to reduce the radioactive inventory. A variety of blanket/shield options was examined for both designs and the relative merits of the various materials as a function of blanket/shield thickness were demonstrated. The lifetime of the structural components was determined based on the radiation-induced damage in V and SiC. In this paper, a comparison between the two designs based on detailed neutronics analysis is presented.
