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.”

Neutronics experiments for an annular blanket system have been performed using a simulated line DT neutron source. The line source was simulated by moving point source in which the annular blanket was oscillated relatively on the axis of the DT neutron target. The measurements were performed in both ways of continuous and stepwise motions. The former was applied to heavy irradiation experiments such as the foil activation method for reaction rate and Li2O pellet technique for tritium production rate (TPR). The latter was to on-line methods such as NE213 and Li-glass scintillators for spectrum and TPR of 6Li and 7Li. Especially the latter case provides contribution of neutrons generated at each point on the line source to the reaction at the detector position. This corresponds to an importance distribution at the center axis of the annular system and can be compared to the calculated adjoint flux at the source positions.
