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.”

This CIA report on India, “India’s Nuclear Procurement Strategy: Implications for the United States,” has comparatively few excisions. It discusses in some detail Indian efforts to support its nuclear power and nuclear weapons development program by circumventing international controls through purchases of sensitive technology on “gray markets.” The report depicts a “growing crisis in the Indian civil nuclear program,” which combined with meeting nuclear weapons development goals, was forcing India to expand imports of nuclear-related supplies. The purchasing activities posed a “direct challenge to longstanding US efforts to work with other supplier nations … for tighter export controls.”

This massively excised report indicates the Agency’s strong views about releasing its knowledge of India’s nuclear weapons activities, even when the information is decades old. That many of the pages are classified “Top Secret Umbra” suggests that some of the information draws on communications intelligence intercepts, another highly sensitive matter.
