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.”

As an important means of safety research in nuclear power plant, thermal hydraulic test verification has attracted the attention of many countries such as United States, Russia, France, Japan, South Korea and other advanced countries in nuclear field. In the 30 years of research and development of nuclear power plants in China, a large number of thermal hydraulic tests have been carried out. This article investigated the thermal hydraulic test facilities and China's thermal-hydraulic overall effect tests. China's three major nuclear power groups have built and operated several thermal hydraulic verification test facilities, but the objects and contents of these test facilities are targeted only for specific reactor types, and there are deficiencies in the systematization and universality of thermal hydraulic verification capabilities. Some universities in China have also carried out thermal hydraulic verification of some nuclear power plants. However, these types of test facilities are small in size and are not suitable for engineering verification. Therefore, in terms of test facilities in China, we still need to design and construct test facilities that can both meet the need of the active and passive systems, and make up the inadequacies of the thermal hydraulic verification of the primary loop system and the safety system.
