DUBAI (Reuters) - Iran is prepared to modify its planned Arak heavy water reactor to help allay Western concerns, its nuclear energy chief said in published remarks that could be the first such suggestion by a senior Iranian official.
Western powers, preparing for negotiations with Iran on a long-term deal defining the scope of its disputed nuclear programme, fear Arak could provide a supply of plutonium - one of two materials, along with highly enriched uranium, that can be used for the core of a nuclear weapon - once operational.
