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.”

Ripple Reduction Poloidal Field (RRPF) coils together with blocks of ferro-magnetic iron shielding are used to design a commerical tokamak reactor similar in size to STARFIRE with only eight rather than twelve toroidal field (TF) coils. The RRPF coils function like segmented poloidal field coils, placed between the TF coils and the neutron shielding, carrying an average of ±6 MA turns of current in the torroidal direction. Together with an additional pair of vertical field coils carrying 4.8 MAT, they produce the poloidal field needed for a β ∼ 6% plasma equilibrium with elongation 1.68 and a pair of separatrices suitable for a poloidal divertor. The RRPF coils also reduce magnetic ripple near the top and bottom of the plasma while the laminated blocks of iron magnetic shielding placed under each TF coil reduce magnetic ripple at the outer edge of the plasma near the midplane from a maximum of 5.48% to less than 1%.
