North Korea is continuing to operate its 5-megawatt reactor at the regime's Yongbyon nuclear complex and is constructing a new building near its Experimental Light Water Reactor.
This is according to IAEA chief Rafael Grossi on Wednesday, who added that a nearby radiochemistry lab has seemingly not been functional since July.
While pointing out the new building, once constructed, may be used to establish a nuclear reactor or for facility management, Grossi expressed deep regret over Pyeongyang's continuous nuclear activities which violate UN Security Council resolutions.
Commercial satellite imagery from 38 North on Wednesday provided further evidence that the 5-megawatt reactor is operational, showing steam emanating from the site.
That indicates at least one of the generators is active.
The U.S. website, which monitors the regime, also said in its latest article that water continues to be discharged from an auxiliary pipe into a channel leading to the Kuryong River.
The 5-megawatt reactor, which appeared to be shut down from 2018 until recent months, can produce up to six kilograms of plutonium a year.
The latest activity is notable as the resumption of plutonium production is likely needed to accomplish the targets for further nuclear weapons development, set at the regime's eighth party congress in January.
South Korea's unification ministry said Thursday that Seoul and international organizations are in close contact to analyze the North's recent activity.
Making it clear that this activity goes against UN Security Council resolutions, the ministry underlined that the terms of the agreement made on denuclearization of the Korean Peninsula by the two Koreas and the U.S. should be met.
