On February 7, 1993, a Site Area Emergency was declared at the Thee Mile Island Nuclear plant after an intruder drove his station wagon through a protected area fence and crashed into a turbine building roll-up door. After a 4-hour search, the unarmed intruder was apprehended beneath the Unit 1 main condenser by site security and turned over to the Pennsylvania State Police. The intruder had recently been released from a psychiatric ward of a local hospital. The vital areas of the plant, including the control room, remained locked throughout the event and were not penetrated by the intruder. The plant remained at 100 percent power throughout the event. A comprehensive search of the entire facility was completed prior to termination of the emergency. No evidence of explosives or accomplices was found.
