Minor water leaks force Browns Ferry 2 offline

The Tennessee Valley Authority (TVA) took Unit 2 of the Browns Ferry nuclear plant in Alabama offline about 10 CT on Sunday, Aug. 3, after the discovery of “two minor water leaks inside a section of the unit’s primary containment structure,” according to a TVA spokesperson.

“All systems performed as designed and there was no danger to the public or plant personnel,” the spokesperson said in response to an email inquiry from GenerationHub.

Repairs are currently underway and, once successfully completed, the unit will be returned to operation, the spokesperson said. No details were offered on when the unit might return to service.

More details could surface on Aug. 5 when TVA President and CEO Bill Johnson discusses TVA’s quarterly financial performance in a 9:30 a.m. EDT conference call.

The Browns Ferry nuclear complex in Limestone County, Ala., is one of the nation’s largest nuclear stations. Each of the Browns Ferry units is a 1970s vintage boiling water reactor (BWR) with a generating capacity of roughly 1,100 MW.

The other two Browns Ferry units are operating as normal.
