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 Advanced Space Propulsion Laboratory (ASPL) is developing a Variable Specific Impulse Magnetoplasma Rocket (VASIMR) using a Radio Frequency (RF) heated magnetic mirror operated asymmetrically. The system comprises of three stages: 1) plasma ionization and injection into the magnetic system; 2) ion heating by action of Ion Cyclotron Resonance Heating (ICRH); 3) plasma exhaust through a magnetic nozzle. The central experimental device is a small versatile tandem mirror configured system. The system can also be easily reconfigured to operate as a simple mirror. The total length of the device is 3.2 m, and the maximum magnetic field is 3.0 T. The exhaust end connects to a 5 m vacuum chamber where we are installing a 40,000 liter/second pumping capacity. Radio frequency power is available at approximately 3 MHz at up to 200 kW. A set of plasma diagnostics is being developed and installed, starting with two fast reciprocating probes, one quadruple Langmuir and one Mach.2 We are now evaluating the use of a helicon3 RF plasma source for an efficient ionization stage of the system. Initial results from experiments using a single double-half turn antenna are presented. In addition, we are exploring the use of a Lorentz Force Accelerator (LFA) as a plasma injector source.4
