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.”

Specific features of metabolism of different classes of tritium compounds have been studied in experiments with rats and mice. The results indicated the value of intracellular content of water is by 15–40% less than the average content of water in the whole tissue. Protracted retention in lungs of particles of luminous compounds and Ti tritide inhalated or introduced into trachea was shown. So, the particles are assigned to class Y according to ICRP. Foreign low-molecular organic tritium compounds are effectively excreted with urine. Biogenic tritium compounds are bound in tissues at synthesis of biopolymers in dependence on need of body in them. According to our experiments, 1 to 90 % of tritium is separated from all incorporated compounds into body water in the form of HTO. The obtained metabolic data along with results of new radiobiological experiments on mice for RBE and biogenic tritium compounds effectiveness were the basis for development and introduction in Russia of standards for insoluble and biogenic tritium compounds and separately - for labelled precursors of nucleic acids.
