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.”

As the main additional heating system and the only means to heat the ions, ion cyclotron resonance heating (ICRH) plays a central role in plasma scenario developments on Tore Supra. Conversely, the specific focus of Tore Supra toward long-duration discharges places its heating system in an original position in the ion cyclotron community. High-power long-pulse requirements motivated innovative design choices and operational methods. Over long pulses, the physics of rf waves in the plasma edge early emerged as a crucial issue that was abundantly studied and benefited from original diagnostic techniques, some of which still remain unique in the magnetic fusion community. This paper reviews ICRH technology and physics on Tore Supra, from the generators and antennas to the central plasma via the scrape-off layer. Emphasis is put on the experience gained over 20 years of experimental and theoretical activity. Lessons are drawn for next-step devices.
