Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.”

This paper describes present status of magnetic measurements in the Large Helical Device (LHD). The magnetic measurements have been mainly applied for estimation of global parameters and for magnetohydrodynamic (MHD) study rather than the equilibrium control because of net current-free plasmas. The techniques of diamagnetic flux measurement and MHD mode analysis are introduced. The estimation of the diamagnetic flux strongly depends on the plasma currents inducing an eddy current on continuous helical coils. The obtained diamagnetic energy is almost consistent with kinetic energy within the measurement error. The MHD modes have been identified through comparison of magnetic probe signals with virtual perturbation generated by multifilament currents on Boozer coordinates based on three-dimensional MHD equilibria. The validity of this technique was considered through the pressure gradient control experiments.
