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.”

In a core transient simulation, the initial condition of the simulation should be consistent with the real core state. The initial iodine and xenon distributions, which cannot be measured in the core, have significant effects on the transient with xenon dynamics of a pressurized water reactor. In simulating the transient starting from a nonequilibrium xenon state, accurate initialization of the nonequilibrium iodine and xenon distribution is essential to predict the core transient behavior. An initialization method that uses the iodine and xenon states to predict a core transient starting from a nonequilibrium xenon condition is developed through the analytical treatment of the relationship between power and the iodine and xenon distributions. An application of this method is provided by simulating a transient in the start-up test of Yonggwang Unit 3.
