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 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.”

One of the major components in a fusion reactor for which a safety analysis must be carried out is the magnet system. We attempt to provide a systematic answer to the hazard potential of superconducting magnets for fusion. Event trees are developed, demonstrating the predictable behavior in all cases. It can be seen that usual failure events cause only a temporary shutdown of the magnet system without damage. Less likely accidental events will lead to single-current arcs with moderate internal damage of a single coil. Only sudden complete rupture of a turn can be followed by a multiple-current arcing resulting in a very high power arc with a certain probability of burning through the coil case, thus damaging other reactor components before extinction. Missile generation of winding parts can only occur in the very hypothetical case of simultaneous rupture of the winding at a sufficiently large distance apart. Even then, the developed kinetic energy will be less than that of airplane crashes considered in the safety analysis of nuclear power plants.
