IAEA: Renewed Activity at N. Korea Nuclear Reactor 'Deeply Troubling'

VIENNA - North Korea appears to have restarted a nuclear reactor that is widely believed to have produced plutonium for nuclear weapons, the U.N. atomic watchdog said in an annual report, highlighting the isolated nation’s efforts to expand its arsenal. 

The signs of operation at the 5-megawatt (MW) reactor, which is seen as capable of producing weapons-grade plutonium, were the first to be spotted since late 2018, the International Atomic Energy Agency said in the report, dated Friday.  “Since early July 2021, there have been indications, including the discharge of cooling water, consistent with the operation,” the IAEA report said of the reactor at Yongbyon, a nuclear complex at the heart of North Korea’s nuclear program.  The IAEA has had no access to North Korea since Pyongyang expelled its inspectors in 2009. The country subsequently pressed ahead with its nuclear weapons program and soon resumed nuclear testing. Its last nuclear test was in 2017.
