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.”

A test facility for a full-scale prototype of the Neutral Beam Injector (NBI) for ITER is planned to be built in Padova, Italy, in the framework of the European activities in support of ITER. Two possible sites were considered: the site hosting RFX (Reversed Field eXperiment), connected to the 400-kV transmission network, and the site hosting the National Institute for Nuclear Physics (INFN), connected to the 132-kV network. Analyses have been made to evaluate the impact on the two HV networks due to the additional NBI load. A particular aspect was studied in detail: during the NBI operation, very frequent accelerator grids breakdowns are expected, requiring fast de-energization of the main power supplies, followed by voltage re-application in about 50 ms; this can cause active and reactive power steps and consequent voltage fluctuations (flickers) on the HV networks. The analyses are described in the paper and the main results reported and discussed.
