AMS to Support Commissioning of First AP1000 Reactors Being Completed in the U.S.

AMS is supporting the commissioning of the first two Westinghouse AP1000 reactors in the United States with several services such as RTD and pressure transmitter response time testing, baseline cable testing of several systems, and noise analysis after startup. AMS supported similar commissioning work on four AP1000s built in China from 2016 – 2018. The new units at Vogtle will be the first new commercial nuclear reactors to come online in the U.S. since Watts Bar Unit 2 came online in 2016.

In March 2021, AMS performed baseline cable testing of the rod control and rod position indication systems at Vogtle Unit 3 prior to hot functional testing. This was the first time CHAR testing has been performed on rod control assemblies in a Westinghouse AP1000 plant. In April 2021, AMS supported Vogtle with additional testing to help troubleshoot cable issues identified in the rod assembly circuits. This testing helped the site to determine the locations of the anomalies and quickly plan the necessary repairs.

Per Southern Nuclear, the AP1000 reactors are part of the Vogtle Units 3 and 4 expansion project. Once online, the reactors will provide clean reliable power to 1 million homes and businesses in Georgia.
