An 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. According to INR, India had taken the “first deliberate decision in the series leading to a nuclear weapon,” which was to have “available, on demand, unsafeguarded weapons-grade plutonium or, at the least, the capacity to produce it.”
