Iran's permanent representative to the International Atomic Energy Agency (IAEA), Ali-Asghar Soltanieh, said Sunday that Iran has so far produced over 50 kg 20 percent enriched uranium.
Talking to Xinhua on the sidelines of an international nuclear disarmament conference in Tehran on Sunday, Soltanieh said that " We need 120 kg enrichment up to 20 percent. Of course, we have been able to produce successfully over 50 kg."
"But, we still need. We have to speed up," he said, adding that "Because Tehran research reactor is in desperate need for fuel, because Tehran reactor should produce radioisotopes for hospitals. "
