I'm posting this as 'history' with 2 comments and only making the observation that weaknesses/vulnerabilities in this design's safety systems were well-known in 1975 as a result of the 'incident':
1. Take a guess at what design these reactors use (see tag) and, for that matter, when they were built.
2. Take a guess at the initial construction date of the US' first Thorium Reactor...
Oh...and yes, this happened BEFORE Three Mile Island.
Incidentally, FWIW: There ‘is’ a Documentary film on this here
http://www.imdb.com/title/tt1576692/
But good luck finding it (though Amazon has it for Rent/Sale at $19.95/$24.95 respectively streaming & $24.95 DVD)
This was no big deal, just a 185,000 alarm fire. BTW, look up Fermi reactor near Detroit.

I thought this was a key point:
>>How the Fire was Extinguished
The electrical cables continued to burn for another six hours, because the fire fighting was carried out by plant employees, despite the fact that professional firemen from the Athens, Alabama, fire department had been on the scene since about 1:30 p m.<<
Had they allowed the Athens, Alabama fire department to fight the fire, it would have been extinguished long before it had a chance to so all the damage.
