Don’t Bomb Iran

Over 250 kg of Canadian plutonium was sent to the US and used in nuclear weapons from 1955 to 1976. Below is an extract of  a  letter from the US Deputy assistant Secretary for Military Application and Stockpile Management Defense Programs.  That page also describes  Canadian plutonium used in UK weapons .

The majority of the plutonium received from Canada came from the Chalk River Facility. Approximately, 252 kilograms of plutonium in spent reactor fuel was sent to the Savannah River Site where it was processed and blended with other materials in the main production streams for the United States nuclear weapons program.

I hope this information answers your questions. Again, thank you for the use of your photograph and support in the Department’s openness initiatives.

Sincerely,

Thomas P. Seitz
