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 series of experiments, the dosimetry of OBT in the mice supplied with THO or OBT directly or indirectly from their mothers was studied. In the offspring mice nursed by mother mice supplied with THO as drinking water, the largest contribution of OBT to the total accumulated dose was found in the brain. The percent contribution of OBT to the total dose distributed between 17 and 42% among various soft tissues. The OBT localization to cell nuclei increases the microscopic dose to cell nuclei by a factor of 3 – 6 in the case of DNA-bound tritium in comparison with the dose estimated from the tissue-averaged tritium concentration. The tritium localization is of less importance in the case of protein-bound tritium. The blood level tritium was found to be useful and convenient for OBT dosimetry in a practical case of radiation protection of humans after acute and chronic intake of tritium. A new technique was developed to isolate mouse red bone marrow from tibia. A model experiment using mice has shown that the dose to red bone marrow in the case of oral THO intake was lower than the dose estimated for the blood pool.
