ZEEP

The ZEEP (Zero Energy Experimental Pile) reactor was a nuclear reactor built at the Chalk River Laboratories near Chalk River, Ontario, Canada (which superseded the Montreal Laboratory for nuclear research in Canada). ZEEP first went critical at 3:45 PM, September 5, 1945. ZEEP's main international significance is its status as the first operational nuclear reactor outside of the United States.
