Near bomb-grade uranium particles enriched to 83.7 percent found in Iran: UN

Inspectors from the United Nations nuclear watchdog found uranium particles enriched up to 83.7 percent in Iran’s underground Fordo nuclear site, a report seen Tuesday by The Associated Press said.

The confidential quarterly report by the Vienna-based International Atomic Energy Agency distributed to member states likely will renew tensions between Iran and the West over its program.

The IAEA report, which only speaks about “particles,” suggests that Iran isn’t building a stockpile of uranium enriched above 60 percent — the level it has been enriching at from some time.
