(JTA) — Iran said June 17 that it will break the uranium stockpile limit set by the 2015 nuclear deal in the next 10 days.

The Atomic Energy Organization made the announcement at the Arak heavy water nuclear facility. Its spokesman, Behrouz Kamalvandi, also said that Iran had already quadrupled its low-enriched nuclear output, the official state-run Islamic Republic News Agency reported.

Since the Trump administration pulled out of the Iran nuclear deal one year ago, Iran has pushed the limits of breaching the agreement with world powers. China, France, Russia, the United Kingdom, Germany and the European Union remain committed to the Joint Comprehensive Plan of Action.

In May, Iranian President Hassan Rouhani set a 60-day deadline for the powers to set new terms for the nuclear deal, including easing restrictions on Iran’s banking and oil sectors. Iran threatened that if the world powers failed to meet the deadline, it would remove caps on uranium enrichment levels and resume work at Arak.

Renovations have been completed on the Arak heavy water plant, which allows it to increase its capacity. In the next stage of nuclear technology development, Iran will use the extra heavy water, IRNA reported.
