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 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.”

Operation of a tokamak from a remote site has been demonstrated for the first time. The Alcator C-Mod tokamak, located at the Massachusetts Institute of Technology, was operated over the Internet from a remote control room set up at Lawrence Livermore National Laboratory in California. Prescription of the physics parameters such as plasma current, density, shape, heating power, and active diagnostics was accomplished entirely from the remote site using the same interface as when operating from the C-Mod control room. Engineering control of subsystems (e.g., vacuum, cooling, and power supply limits) remained under local control, providing appropriate equipment and personnel security. Although the principal purpose for running this experiment from a distance was to demonstrate the remote operation, it was planned as a productive physics run. The operation was highly successful; important new physics data were obtained, and valuable insight was gained into the potential of remote operation as well as its limitations.
