Entergy Continues Investigation of Failed Transformer, Spilled Dielectric Fluid at Indian Point Energy Center

ENTERGY

Buchanan – Entergy continues to investigate the cause of the failed transformer and subsequent spill of the transformer’s dielectric fluid following the event which occurred on May 9. The failed transformer is located outdoors in the transformer yard and external to any buildings that contain radioactive materials.

Preliminary assessments of the moat system designed to catch the transformer’s dielectric fluid following a transformer failure, along with drains and other areas around the transformer, indicate as of today approximately 8,300 gallons of dielectric fluid have been recovered or were combusted during the fire. Entergy will vigorously investigate and seek to recover as much of the remaining approximately 16,000 gallons as possible.

Entergy officials stated that visual observations in the discharge canal and the Hudson River have not indicated significant quantities of transformer oil, and further investigation and recovery efforts at the site will continue. These efforts likely are anticipated to take several months, and will be coordinated with the New York State Department of Environmental Conservation (NYSDEC).
