Entergy brings Indian Point 3 back online

The Entergy (NYSE:ETR) Indian Point 3 nuclear facility in Buchanan, N.Y., is back in service after being offline since a May 9 transformer fire, an incident which saw a significant amount of fluid leak into the Hudson River.

Indian Point 3 was listed at 82% generation early May 26, according to reactor status data from the Nuclear Regulatory Commission (NRC). The unit had been listed at zero generation the day before.

Entergy had said May 22 that it appears roughly 3,000 gallons of dielectric fluid leaked into the river. Company, state and federal officials are involved with monitoring and cleanup of the river spill.

The failed transformer held approximately 24,000 gallons of dielectric fluid, which acts as an electrical insulator and coolant inside transformers when they are operational.

“I want to thank our entire Indian Point team for their professionalism and dedication to safe operations that enabled unit 3 to safely shut down as expected following the transformer failure and then returned the plant to service,” said Larry Coyle, the Site Vice President and top Entergy official at Indian Point. “We are working with industry experts to understand the cause of this transformer failure in order to help prevent a recurrence.”

Indian Point Units 2 and 3 are both pressurized water reactors (PWRs) and each is listed with an operating capacity of roughly 1,000 MW.

Units 2 and 3 are in the midst of a protracted and contested license renewal case before the NRC. Critics such as the Riverkeeper organization have used the recent fire-and-spill as another example of why the nuclear units should not get a 20-year license extension.
