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 its resolution of January 1, 1985, the federal government of Germany deemed it necessary to develop, complementary to reprocessing, the direct disposal of spent fuel. The Deutsche Gesellschaft zum Bau und Betrieb von Endlagern für Abfallstoffe was in charge of the implementation of demonstration tests aimed at proving the state of engineering readiness and planning of different repository concepts.Several repository alternatives (borehole emplacement, drift emplacement) including different waste packages, cooling times, and technical equipment, etc., were compared. As a result, a reference and a backup concept were elaborated and subsequently examined in detail. Temperature calculations were carried out for a site-independent case and for a case using the working model of the Gorleben salt dome, which displays a horizontal cut of the geological structure of the salt dome.The demonstration tests were intended for confirming technical feasibility under realistic conditions. They comprised simulation tests for shaft transport of heavy loads, handling tests of drift disposal, and active handling experiments with neutron sources.
