The report also concluded that the SRE meltdown caused the release of more than 458 times the amount of radioactivity released by the Three Mile Island accident. While the nuclear core of the SRE released 10 times less radiation than the TMI incident, the lack of proper containment such as concrete structures caused this radiation to be ...
