Tehranian atomic chief "Ali Akbar Salehi" told the ISNA news agency that said Iranian Arak heavy water reactor is incapable of producing plutonium for use in a nuclear weapon.
Salehi underlined that "the Arak research reactor cannot produce plutonium that could be used to make an atomic bomb since the plutonium will remain in the reactor's core for a year", adding "Anyway, Iran doesn't have a reprocessing plant" to purify plutonium for such use"
The Arak site is of concern to the West because Tehran could theoretically extract weapons-grade plutonium from its spent fuel if it also builds a reprocessing facility.
Iran agreed not to build such a facility as part of last month's nuclear deal. It also committed not to make further advances at its Arak, Fordo and Natanz facilities.
Salehi said dismantling the Arak reactor or giving up uranium enrichment is "a red line which we will never cross", noting that "when International Atomic Energy Agency cameras are installed and constantly monitoring the reactor and inspectors can visit, there will no longer be cause for concern".
