Historical Documents Regarding India's Misuse of Civilian Nuclear
Technology Assistance
India’s 1974 nuclear weapon test explosion used plutonium
produced by a Canadian-supplied reactor
(CIRUS) moderated with heavy water supplied by the United States
under a 1956 contract stipulating that it be used only “for
research into and the use of atomic energy ‘for peaceful purposes.’”
To this day, India does not deny the 1974 test device used Canadian
and U.S. equipment and materials, but asserts that it did not violate
the terms of its U.S. and Canadian “peaceful uses” contract
equirements because the test was a “peaceful nuclear explosion.”
In January 2006, the State Department said that there is “factual
uncertainty as to whether U.S.-supplied heavy water contributed
to the production of the plutonium used for the explosive device,
and the lack of a mutual understanding between the U.S. and India
on the scope of the 1956 contract language. We have since made clear
that we exclude so-called ‘peaceful nuclear explosions’—and
any other nuclear explosive activity—from the scope of peaceful
nuclear cooperation.”
However, the following recently declassified documents show that
the United States and Canadian governments interpreted their agreements
as “precluding all nuclear explosions on the grounds that any
such explosion in tantamount to a nuclear weapons test” and
made this interpretation clear to India before the 1974 bomb test.
