Iran increased its output of enriched uranium that world powers are concerned may eventually be used for a nuclear weapon, according to International Atomic Energy Agency inspectors.
While the United Nations agency verified that Iran hasn’t diverted its declared nuclear material for weapons use, the inspectors reiterated past statements that they can’t give assurances that Iran isn’t concealing nuclear activities.

Iran almost doubled its stockpile of 20 percent medium- enriched uranium, to 145 kilograms (320 pounds), from 73.7 kilograms in February, the IAEA said yesterday in an 11-page report. Iran had tripled its production of the material in the three months ending Feb. 24.
IAEA inspectors reported they found the presence of particles of 27 percent-enriched uranium at Iran’s Fordo facility. The particles were a result of “technical reasons beyond the operator’s control,” Iran told the Vienna-based agency, which is looking into the matter. Uranium enriched over 20 percent is considered highly enriched, though most nuclear bombs use the heavy metal purified to 90 percent levels.
The report is the first since IAEA Director General Yukiya Amano returned from Iran on May 21 with a commitment from the Islamic republic’s government to improve cooperation with inspectors. While the Persian Gulf nation insists that its atomic work is peaceful, it has been under IAEA scrutiny since 2003 over evidence that it seeks nuclear-weapon capabilities.
‘A Glitch’
The uranium particles enriched to 27 percent could be the result of a transient condition that can occur when the material is fed into centrifuges, according to two senior international officials familiar with the investigation. The officials spoke on condition of anonymity because of the issue’s sensitivity.
