A fuel core meltdown occurred at 3:07 p.m. on Friday, December 12th, 1952 at the Chalk River Experimental NRX Reactor Facility near Ottawa, Ontario, Canada. Four neutron absorbing control rods failed to descend into the core, due to this failure, a pressure built up in containment area causing a 4 tonne gas holder dome to be blown some 4 feet in the air and jammed it self into the super structure. Radiation was released into the air and millions of gallons of radioactive water was released into the Ottawa River. The reactor core was then buried, as if it were radioactive waste.

Oh and get this, one if the clean up crew members was/became a US President – Jimmy Carter.

- Wikipedia – List of nuclear power accidents by country
Worldwide, many nuclear accidents have occurred since the Chernobyl disaster in 1986. Two thirds of these mishaps occurred in the US. The French Atomic Energy Commission (CEA) has concluded that technical innovation cannot eliminate the risk of human errors in nuclear plant operation.
- Wikipedia – Nuclear power in CanadaNuclear power in Canada is provided by 19 commercial reactors with a net capacity of 13.5 Gigawatts (GWe), producing a total of 95.6 Terawatt-hours (TWh) of electricity, which accounted for 16.6% of the nation’s total electric energy generation in 2015. All but one of these reactors are located in Ontario where they produced 60% of the province’s electricity in 2015 (92.3 TWh). Seven smaller reactors are used for research and to produce radioactive isotopes for nuclear medicine.
