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 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. 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 fusion plasma, the behaviour of impurities is important. In order to study the behaviour of impurities spectroscopic measurement is necessary. We are now studying EUV spectra from Large Helical Device (LHD) to study the behaviour of impurities. We present here the three kinds of EUV spectra measured from LHD.In order to analyse the observed spectra, we need atomic data. We use collisional radiative models of different ions to estimate the line intensities. To construct a collisional radiative model we need a lot of atomic data between excited states. Model and atomic data are coupled. To derive correct answers from a model we need reliable atomic data.
