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.”

Stellarators are steady state, have an absence of disruptive instabilities, have low recirculating power, and are natural divertors—all of which are intrinsic properties that make stellarators especially attractive as fusion reactors. The question is addressed of the minimum size requirements for a stellarator reactor, independent of the specific configuration chosen to optimize physics and technology aspects. A one-dimensional model is used to deduce by postulating specific plasma profiles the power balance between alpha-particle heating, radiation, and conductive losses in the plasma and to determine the minimum size compatible with the level of output power of the reactor and the operational limits due to plasma confinement, pressure, and density. Also considered is the influence on stellarator reactor size requirements of particle accumulation and of the presence of impurities in the plasma. Additionally, with regard to practical realization of the device, the limitations of wall power deposition and device aspect ratio are considered. Available stellarator reactor designs are reviewed based on these results.
