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.”

The Center for Electromechanics has designed, fabricated, and is now operating a prototype of a full torus, 20 Tesla (T) on-axis, single turn, toroidal field (TF) magnet system powered by the Balcones Homopolar Generators (HPGs). This magnet system is part of the Ignition Technology Demonstration (ITD) program for the fusion ignition experiment (IGNITEX). The six HPGs connected to the prototype magnet in parallel are capable of producing a 9 MA, 150 ms, current pulse required for a 20 T ITD test. The diagnostic system for the prototype magnet is designed to determine strains, temperatures, and magnetic fields at several locations in the TF magnet. These values are used to verify numerical predictions by electromechanical and thermomechanical analyses. Operating conditions for the instrumentation inside the cryogenically cooled magnet are extreme; localized temperatures inside the magnet can rise from - 196°C to 200°C during the current pulse and the magnet field levels near the inner leg surface can rise to 30 T in 30 ms. The specifications, testing, and layout of the diagnostic and data acquisition systems for the ITD prototype are presented in this paper.
