SEOUL, South Korea – U.S. and South Korean authorities have found no concrete evidence yet that North Korea is reprocessing spent nuclear fuel rods to harvest weapons-grade plutonium, a news report said Wednesday.
North Korea said last month it had begun the reprocessing work at its once-mothballed Yongbyon nuclear complex — one of a series of steps the communist nation has taken in protest over international criticism of its April 5 rocket launch.
