Steved,
that's ironic! That would have been Fermi #1 in Monroe. Do you know it's fate? Fermi #2 was built after the core meltdown of 1965. We moved from Pittsbirgh in fall of 1966.
The reactor overheat was caused by a cooling fin which dislodged from inside a line and jammed a valve. The reactor was scrammed within minutes of the hot core eating through the containmnet floor.
It is forever entombed in lead.
I read the book "We almost lost Detroit".
Babcock and Wilcox welded the entire reactor vessel and cooling lines.
