The Iranian Nuclear Agency, according to information obtained by Adnkronos International (AKI) is preparing to announce new successes in its researchers working on uranium enrichment.
"At Natanz our scientsts have managed to enrich uranium beyond 3.5 percent," he said. An announcement which contradicts with the statements from government officials who insist on the civilian use of its nuclear programme. When used for powering nuclear power plants for civilian use, uranium must be enriched to 3.5 per cent.
