Iran's nuclear chief indicated that "we do not need 20 per cent enrichment for now, because we have enough resources of 20 per cent enriched uranium for some... years. And if we produce some, we should store them". Referring to enriched uranium, he added that "if we wish we can remove this 300kg limit... if we withdraw from the JCPOA, we can exceed this volume and use it for production of the required fuel for the Arak reactor".
