Electrical Transformer Fails, Shuts Down Palo Verde Nuke Plant

August 6, 1986 GMT

WINTERSBURG, Ariz. (AP) _ The failure of an electrical transformer triggered the shutdown of both operating units at the Palo Verde Nuclear Generating Station today, said a plant spokesman.

Dan Canady said he did not know when the Unit 1 and 2 generators would resume operation, explaining that engineers first would have to determine what caused the transformer failure.

When the transformer which serves both units quit at 4:32 a.m., the units automatically shut down, said Canady.

The shutdown falls under the category of an ″unusual event,″ and thus was reported to the Nuclear Regulatory Commission, he said.

Canady said there was no health or safety threat to plant employees or the public. The plant is located 50 miles west of Phoenix.
