FitzPatrick Nuclear Power Plant Remains Offline After Transformer Fires

This weekend, a transformer fire at the FitzPatrick Nuclear Power Plant shut down the Fukushima-style BWR reactor, and has sidelined the station until a new transformer is installed.

The reactor shut down automatically early Sunday morning, at 3:55 am, after fires broke out in the plant’s main transformer (T-1A), which converts electricity to higher voltage before sending it onto the grid.  At 5:45 am the plant entered the emergency plan at the NUE level due to inability to successfully extinguish the fire.

FitzPatrick’s on-site fire brigade, which has one truck, called for assistance from the nearby Scriba Volunteer Fire Department, which sent a truck and firefighters to help put out the blaze, Holden said. The New Haven fire department was put on standby but did not go to the site, Holden said.

The fire was extinguished at 6:32 am, more than two and a half hours after it began.  Firefighters then had to turn their attention to fire in the T-1A bus ductwork.  Around ten minutes later emergency workers brought the T-1A bus ductwork fire under control.  The Unusual Event (HU 6.1) was terminated at 8:01 am.

The station is forced to remain shut down until the cause of the fire is determined and repairs are made.  The site is owned and operated by Entergy, who said they were unable to predict when the reactor would return to service.

This was the second time the plant had shut down in a week.  The first shutdown occurred after the turbine stopped unexpectedly during routine testing.
