North Korea's Yongbyon reactor 'nearing operation'
Steam has been seen rising from North Korea's Yongbyon nuclear facility, suggesting that the reactor has been restarted, a US institute says.
The colour and volume of the steam indicated that the reactor was in or nearing operation, the institute said.
Pyongyang vowed to restart facilities at its main Yongbyon nuclear complex in April, amid high regional tensions.
The reactor can produce plutonium, which North Korea could use to make nuclear weapons.
The report, which was published on the 38 North website, was written by the US-Korea Institute at Johns Hopkins University. The institute uses satellite imagery to monitor developments in North Korea.
The reactor uses steam turbines to generate electricity, and the steam seen in satellite imagery from 31 August indicated that the electrical system was about to come online, the report said.
"The reactor looks like it either is or will within a matter of days be fully operational, and as soon as that happens, it will start producing plutonium," report author Jeffrey Lewis told the BBC.
