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.”

Estimates of the time-to-melt for cryogenic DT inertial fusion targets in the presence of thermal radiation are presented. This time is defined as that required for thermal radiation in a hypothetical reactor to raise the temperature of small polymer capsules containing solid DT by 1 K and to fully liquefy the contents. The time estimates are in turn based on estimates of the infrared absorption spectra of both solid DT and the polymer capsule material. Assuming typical target dimensions and rapid equilibration of the target temperature, the estimates show that the absorption of thermal radiation and subsequent heating of likely capsule materials will dominate the corresponding quantities of DT ice and thus that the former effect largely determines the time-to-melt of the target. Specific estimates are made for capsules fabricated from KaptonTM polyimide. Comparisons are also made for capsules coated with reflective metal coatings, and the potential benefit of these coatings is discussed.
