An experimental civil reactor near the then large and still mostly industrial town of Detroit, Michigan. The city is on the American border with Canada.
The 1966 incident
The core of an experimental reactor near Detroit, Michigan, had partially melted down when a sodium cooling system failed on October 5th, 1966. The core of an experimental reactor melted partially when a zirconium plate at the bottom of a reactor vessel came loose during a test, cause it malfunction, after which a sodium cooling system failed and so 2 fuel sub-assemblies to begin to meltdown. When the plant's radiation monitors sounded, the operators shut down the reactor manually.
It dose not officially have a INES rateing, but probably was a Level 4 INES Scale event.
