Shimon Yiftach

Shimon Yiftach was the director of scientific programs for the Israeli defense ministry.

Shimon Yiftach was the director of scientific programs for the Israeli defense ministry. He was trained at the Argonne National Laboratory in Illinois and was one of Israel's leading experts in the chemistry of plutonium. In December 1963, he publicly stated that the advanced reactor at Dimona would produce plutonium as a by-product, but insisted that the Israeli government had no plans to build a separate plant for chemically reprocessing plutonium. Yiftach knew this was false, as French construction companies had already restarted work on the underground reprocessing plant at Dimona.1
