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.”

A beam loss monitoring (BLM) system for a linear accelerator (LINAC) and booster has been designed and implemented at the Shanghai Synchrotron Radiation Facility, which is under construction. It is a distributed system, constructed with 54 detectors, 11 data collectors, and a console personal computer. Several experiments were made at the National Synchrotron Radiation Laboratory to verify the performance of this system, and one comparison experiment with thermoluminescent dosimeters for dose rate measurement was also done. From preliminary experiments and commissioning, this BLM system is proving to be functional and a useful tool to study the machine status. Moreover, it is hoped that this can be developed into a new method to measure the radiation dose distribution around the LINAC and booster directly, which would help the shielding calculation for future facilities, although more quantitative experiments are needed.
