On September 24, 1977 the Davis Besse Nuclear Power Plant (DBNPP) near Toledo Ohio experienced an event remarkably similar to the Three Mile Island (TMI) Unit 2 accident. The Reactor Coolant System response for both events is virtually identical for about twenty minutes.
The failure of the Nuclear Industry and its Regulatory body, the Nuclear Regulatory Commission, to correctly understand the significance of the Davis Besse event put the TMI Operators in exactly the same position faced by the DBNPP Operators eighteen months later. The results of that failure had dire consequences for both the US Nuclear Industry and the reputations of the TMI Control Room Operators.
This web site is my attempt to tell the truth, the whole truth and nothing but the truth about the Root Cause of the TMI Accident.
