Recent satellite images suggest North Korea may have shut down the nuclear reactor seen as its main source of weapons-grade plutonium, a US think-tank said Saturday, October 4.

Last month, the International Atomic Energy Agency (IAEA) in Vienna said satellite photos showing steam discharges and cooling water outflows suggested the reactor was operational.

But the ISIS report said that in the latest images „both these signatures are missing,“ suggesting the reactor had been „partially or completely shut down.“
