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.”

The conceptual project APEX (Adapted Plasma Experiment) is discussed. The APEX objective is the development of a physical foundations for the CW fusion reactor, created on a base of an alternative type of magnetic trap, which could provide a “tokamak scale” confinement time at much higher β. Linked mirrors are the prototypes of this heading. The main idea of DRACON trap – the short circuit secondary plasma currents inside the curve elements (CE) – is kept. The new principle of poloidal pseudosymmetry and the non-traditional scheme of MHD plasma stabilization by “magnetic hump” give a possibility of a new approach to reduce plasma losses.
The APEX concept provides for the Experimental Pseudo SYmmetric Linked trap (EPSYLON) design. The whole installation will be have two axisymmetric mirror parts (OME) closed with two CEs. Each OME contains the diverter. CE should have a strongly rippled magnetic field. As far as each OME and each CE is a trap with mirror confinement it is possible to start an investigation of the system from separate experiments with different parts of the whole system. The EPSYLON construction will be adapted to the experimental results. The experiment with OME is chosen now as the first step of the program. The main objective of this first experiment is the investigation of the “magnetic hump” MHD stabilization produced by divertor. EPSILON-OME installation is discussed. The closed system calculations are going in parallel.
