Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.”

In the tandem mirror GAMMA 10, a 500 kW gyrotron was newly equipped in the central-cell ECRH system, following the plug ECRH systems. Then, the transmission system for the central-cell ECRH, including a taper, mirrors and a polarizer, has been designed correspondingly. The guidelines to design the transmission system are to make the beam cross section axisymmetrical on the resonance surface with a high power transmission rate and high heating efficiency. According to the guidelines, mirrors in the launcher systems have been designed with our electromagnetic code. Controlling polarization of the incident microwave is achieved with a polarizer for raising heating efficiency.
