Seoul, Safar 13, 1437, November 25, 2015, SPA -- A new nuclear deal came into force Wednesday between Seoul and Washington, opening the possibility of South Korea developing its own capacity to process nuclear material for fuel, dpa reported. The country's 23 nuclear power plants generate one third of its electricity, but are supplied by processed fuel delivered from the US, which has refused to allow South Korea to process any itself. The new deal does not directly approve South Korea's processing of nuclear material but provides for the possibility subject to future approval by Washington. The new terms, agreed in April, will be in place for 20 years, replacing a 1974 treaty. "The new deal is a win-win deal that will strengthen the US-South Korea alliance," Joo Chul-Gi, South Korea's foreign affairs and security chief, told Yonhap News Agency in April. --SPA 13:25 LOCAL TIME 10:25 GMT www.spa.gov.sa/w
