Head of the Atomic Energy Organization of Iran (AEOI) Ali Akbar Salehi announced on Sunday that the country is taking the preliminary steps to produce what he called "modern 20%-enriched uranium" to fuel the country's reactors.
"The preliminary moves have started to design modern 20%-enriched fuel and we are on the threshold of it," Salehi said.
"It is a product different from the former 20%-enriched fuel which could be used to fuel whatever reactor we build like the Tehran reactor," he added.
"The nuclear reactor in Tehran has been working with the old fuel so far, but the modern fuel will increase its efficiency," Salehi said.
The AEOI head had earlier warned that his country enjoyed the capability to restore 20-percent uranium enrichment if the 2015 nuclear deal was discarded by parties still remaining under the agreement.
Salehi said in December that under the 2015 nuclear deal, Iran accepted to put confidence-building curbs on its nuclear program, but they do not obstruct the “peaceful activities of Iran’s nuclear industry”.
“Enrichment is currently underway, but we would put aside the 300kg limit (set by the nuclear agreement) whenever we wish, and would do the enrichment at any volume and level,” he said in an interview with state TV on the sidelines of a visit to the Fordo nuclear facility.
“We currently have 1,044 centrifuges in Fordo, and if the establishment wants, we will restart 20-percent uranium enrichment in Fordo,” he noted
