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.”

In the next years the Gesellschaft fuer Schwerionenforschung and international partners will realize the new international accelerator Facility for Antiproton and Ion Research (FAIR) for research with heavy ions, radioactive ions, and antiprotons. Two important storage rings of FAIR are the collector ring (CR) and the recycled experimental storage ring (RESR), which are located together in the same building: The CR is optimized for fast cooling of heavy ions and antiprotons, while the RESR is mainly used for accumulation of antiprotons.The concrete shielding for the CR and RESR is presented on the basis of several Monte Carlo simulations for radiation transport with the latest version of the FLUKA code. Extensive shielding calculations had to be done because of diverse beam types including different locations of beam losses. The goal of the simulations is to reveal possible weak points in the shielding and to ensure a dose rate outside the storage rings and in the technical supplies' room to a value of <0.5 Sv/h so that this area is accessible without any restrictions.
