Краткий перевод - послеприсоединения ЮАР к ДНЯО в 1991 г страну посетили инспекторы МАГАТЭ, которые заподозрели начилие по итогам своих инспекций наличие военной ядерной программы. А ЮАР это признала лишь в 1993 г.
However, soon after International Atomic Energy Agency (IAEA) inspectors began to visit South Africa's nuclear facilities in 1991, they suspected that there had been a nuclear weapons program. Their suspicions centered on a large inventory of weapon-grade uranium metal stored at the AEC's Pelindaba Nuclear Research Center, 25 kilometers west of Pretoria. This stockpile had been declared to the IAEA as part of the accounting of the nuclear material.
