On July 17, personnel noticed arcing and glowing on the Unit 3 main transformer bus duct and manually tripped the main turbine generator. The buses did not transfer as expected and the reactor automatically shut down due to loss of coolant pumps, with emergency feedwater actuated. Atmospheric vents were opened to release the steam.
