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.”

An integrated 0-dimensional plasma-control code, ASH, has been developed and employed to study the possibility of controlling the burn condition of an ITER-type fusion reactor by modulating the refueling rate. A key feature of this study is the incorporation of robust control theory to allow for modeling uncertainties. A constant gain proportional feedback controller is synthesized; the values of feedback gains are obtained by the algorithm. With this control method, modulation of the refueling rate alone can potentially stabilize fusion burn with the alpha confinement time , or controller delay τdelay = 1.5τE, or D-T recycling ratio 98%. These limitations are fairly restrictive, indicating that added control, e.g., via input power modulation, may be necessary.
