Modernizing I&C for operations and maintenance, one phase at a time
The two reactors at Dominion Energy’s Surry plant are among the oldest in the U.S. nuclear fleet. Yet when the plant celebrated its 50th anniversary in 2023, staff could raise a toast to the future. Surry was one of the first plants to file a subsequent license renewal (SLR) application, and in May 2021, it became official: the plant was licensed to operate for a full 80 years, extending its reactors’ lifespans into 2052 and 2053.

The Dynamic behavior of the JT-60 vacuum vessel was examined during its power tests to confirm the validity of the dynamic response analyses of the vacuum vessel. Observed accelerations and displacements showed good linearity with electromagnetic forces and reached maxima of 48 m/s2 in acceleration and 0.46 mm in displacement at full power operation. The observed natural frequency was approximately 50 Hz, showing good agreement with that predicted by the dynamic response analysis. Dynamic response analyses showed that the vibration mode with a natural frequency of 46.3 Hz had a displacement amplitude of around 0.1 mm at the rigid ring under the misfire start-up operation conditions. The difference between the displacement predicted in the dynamic response analyses and that observed at the lateral port could be explained by the lever ratio effect of the lateral port.
