Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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 ant colony optimization algorithm was used to search for a feasible power ascension path for a boiling water reactor. The control action of start-up operation includes control rod movements and core flow rate variations. During the process, the core status should satisfy some constraints such as thermal limits, preconditioning interior operating management recommendation guideline, and power flow operation domain. In addition, the control objective is to reach full power as soon as possible and approach the target control rod pattern as close as possible. The results show that the developed method can obtain the satisfactory power ascension path, which is also comparable to the operation record.
