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.”

Thick-liquid pockets have the potential to protect structural materials and increase power density in heavy-ion fusion chambers. Here we show that cylindrical liquid jets have interesting advantages for creating shielding grids for heavy-ion beam lines. A cylindrical nozzle design with a very low convergence ratio was developed, and the fabrication methods needed for inexpensive numerically-controlled machining of large nozzle arrays demonstrated. Cylindrical jets were studied because they give the highest surface smoothness for a given degree of turbulence suppression, allow flow control to individual nozzles for control of jet pointing, and attenuate target-induced shocks effectively. Improved control of the grid geometry allows the driver energy to be delivered by a larger number of beams. These smaller beams–up to 160 in the example here–improve focusing and reduce neutron collimation up beam lines.
