Pyongyong: North Korea appears to have restarted a nuclear reactor that is widely believed to have produced plutonium for nuclear weapons, the UN 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 (IAEA) 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 programme.
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 programme and soon resumed nuclear testing. Its last nuclear test was in 2017. The IAEA now monitors North Korea from afar, largely through satellite imagery.
Commercial satellite imagery shows water discharge, supporting the conclusion that the reactor is running again, said Jenny Town, director of the US-based 38 North project, which monitors North Korea.
“No way to know why the reactor wasn’t operating previously — although work has been ongoing on the water reservoir over the past year to ensure sufficient water for the cooling systems,” she said.
“The timing seems a little strange to me, given the tendency for flooding in coming weeks or months that could affect reactor operations.”
Last year, 38 North said floods in August may have damaged pump houses linked to Yongbyon, highlighting how vulnerable the nuclear reactor’s cooling systems are to extreme weather events.
Seasonal rains brought floods in some areas this year, state media have said, but there have been no reports yet of threats to the site, the Yongbyon Nuclear Scientific Research Centre.
At a 2019 summit in Vietnam with then-US president Donald Trump, North Korean leader Kim Jong Un offered to dismantle Yongbyon in exchange for relief from a range of international sanctions over nuclear weapons and ballistic missile programmes. Reuters
