As a follow-up to “this post,”:http://www.totalwonkerr.net/2206/indian-weapons-grade-heu I thought I’d post some other related documents from the “National Security Archive.”:http://www.gwu.edu/~nsarchiv/
Obviously, this is a subject I’ve been reading about a little.
Two documents concern India’s centrifuge program. According to “this 1982”:http://www.gwu.edu/~nsarchiv/NSAEBB/NSAEBB187/IN31.pdf assessment, “New Delhi is conducting research into centrifuge enrichment” for nuclear power reactors.
“This”:http://www.gwu.edu/~nsarchiv/NSAEBB/NSAEBB187/IN34.pdf 1988 assessment says that, according to India, New Delhi had “mastered the enrichment process using an ‘experimental centrifuge’.” The assessment describes the centrifuge as “probably similar to a “Zippe”:http://www.npr.org/templates/story/story.php?storyId=4857123 centrifuge.”
Interestingly, “this”:http://www.gwu.edu/~nsarchiv/NSAEBB/NSAEBB187/IN30.pdf 1982 document mentions Indian research on the “Laser Isotope Separation (LIS) method of uranium enrichment,” something I don’t recall hearing about previously. The assessment states that India hadn’t gotten further than “separating sulphur isotopes.”
