During the event, these inadequacies were compounded by design flaws, including poor control design, the use of multiple similar alarms, and a failure of the equipment to clearly indicate coolant inventory level or the position of the stuck-open PORV. TMI training and procedures left operators and management ill-prepared for the deteriorating situation. The mechanical failures were compounded by the initial failure of plant operators to recognize the situation as a loss-of-coolant accident (LOCA). The accident began with failures in the non-nuclear secondary system followed by a stuck-open pilot-operated relief valve (PORV) in the primary system that allowed large amounts of nuclear reactor coolant to escape. On the seven-point International Nuclear Event Scale, it is rated Level 5 – Accident with Wider Consequences. on March 28, 1979, and released radioactive gases and radioactive iodine into the environment.

The Three Mile Island accident was a partial meltdown of the Three Mile Island, Unit 2 (TMI-2) reactor on the Susquehanna River in Londonderry Township, Pennsylvania, near the Pennsylvania capital of Harrisburg.
