Dominion Surry 2 goes offline due to turbine trip

The Dominion (NYSE:D) Surry 2 nuclear unit in Virginia went offline unexpectedly during the weekend after a turbine trip.

Surry Unit 2 went offline before 3 a.m. on Oct. 9 “due to a Main Generator Differential Lockout Turbine Trip,” according to an event report filed with the Nuclear Regulatory Commission (NRC). NRC data still listed Surry 2 at zero power early Oct. 11.

The cause of the generator differential lockout is under investigation. Off-site power remains available. There was no impact on Surry Unit 1, which continued to run at 100% power.

Surry Units 1 and 2 are pressurized water reactor (PWR) facilities located in Surry County, Virginia. The two units together can generate more than 1,600 MW.
