get citationAn intelligence report that the fuel core of the Canadian-Indian Reactor (CIR) at Trombay was being changed every six months raised questions about India’s nuclear objectives: a six-month period was quite short for “normal research reactor operations,” but it was the optimum time for using the CIR’s spent fuel for producing weapons grade plutonium.
