The International Atomic Energy Agency (IAEA) on Thursday said North Korea was still working on its nuclear reactors.
North Korean leader Kim Jong Un had expressed his willingness to discontinue it, while adding that this would depend on reciprocal measures by the United States.
The IAEA, which is watching North Korea via satellites, has observed possible work on the cooling systems of two reactors, IAEA chief, Yukiya Amano, said.
The operating 5-megawatt reactor and an additional reactor that is under construction are part of the Yongbyon nuclear complex, which is suspected of producing fissile material for North Korea’s nuclear weapons programme.
At a meeting of the IAEA’s governing board, Amano also reported activities “consistent with the fabrication of reactor components” and their transfer into the unfinished reactor.
