In March 1993 President de Klerk declared that South Africa had previously developed a limited nuclear capability which had been dismantled and destroyed before South Africa acceded to the NPT. The IAEA sent experts to visit the facilities involved in the abandoned program and to review historical data. It found no indication casting doubt on South Africa's statement that all the highly enriched uranium for weapons had been reported in its initial declaration. Also it has found no indication to suggest that there remain any sensitive components of the nuclear weapons programme which have not been either rendered useless or converted to commercial non-nuclear applications or peaceful nuclear usage. The IAEA declared it had completed its inspection in late 1994 and that South Africa's nuclear weapons facilities had been dismantled.
