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 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. 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.”

Confocal micro X-ray fluorescence (confocal MXRF) is continuing to be explored as a method for characterizing copper and argon doped sputtered beryllium capsules. Previously demonstrated was the utility of confocal MXRF in both the two- and three-dimensional modes and overlaying the data with X-ray micro computed tomography as a method of nondestructive analysis. In this paper, the relative amount of copper dopant was measured as a function of capsule theta, examining the changes in the amounts of copper around the circumference of the capsule and comparing the relative amount of copper between capsules. A theta stage was specially constructed in order to perform line scans through the capsule wall while keeping the geometry of the measurement constant. Four capsules (one unpyrolyzed and three pyrolyzed) were examined with this method. The noise of the measurements averaged 1.43%, and differences within a capsule as a function of theta were 2.15%, with differences between capsules [approximately]13% indicating that the measurement noise was approximately half the overall variation in copper signal and far less than the measured differences between capsules. These differences in the amount of copper within a capsule and between capsules are much greater than that obtained using absorption techniques.
