According to the agency, they have requested design information from the Islamic Republic and are currently waiting for the response.
However, the agency specified that Iran had stayed within the main restrictions on the country's nuclear activities imposed by the 2015 Joint Comprehensive Plan of Action (JCPOA), commonly referred to as the Iran nuclear deal
The IAEA explained that Tehran has not exceeded limits on its stocks of low-enriched uranium and heavy water, and has not enriched uranium exceeding the limit of 3.67 percent purity, the statement indicated.
Iran Nuclear Deal (JCPOA)
The agreement on the Iran nuclear program was signed in July 2015, by Iran and the P5+1 group of nations - the United States, Russia, China, France and the United Kingdom plus Germany. The deal specifies a gradual lifting of sanctions imposed on the country in exchange for it maintaining the peaceful nature of its nuclear program.
The deal, however, was widely denounced by US President Donald Trump, who refused to certify Iran's compliance with the agreement in October 2017, but didn't pull the United States out of the pact.
In January, Trump declared that he would waive sanctions on Iran as required by the JCPOA, but said this would be the last time. The US president also warned of the US withdrawal from the deal if it is not amended and asked the Congress to address the flaws in the "terrible Iran nuclear deal."
The president continued his sharp line towards Iran in the Nuclear Posture Review (NPR), released on February 2, 2018, specifying that the Islamic Republic's policy in the Middle East views US authority in the region as a threat to its goal to become the dominant regional power.
According to the document, Iran continues to fund the largest missile program in the Middle East and could, in the future, threaten or deliver weapons, developing increasingly long-range ballistic missile capabilities, and pursuing its alleged "aggressive efforts" to undermine neighboring governments, casting doubt on its "long-term commitment to foregoing nuclear weapons capability."
