> Japan and Korea are ramping up their nuclear power

Almost.

Before the 2011 Tōhoku earthquake Japan had 54 nuclear reactors with 30% of Japan’s electricity output. Of that only 33 reactors are currently possibly operable and of those only 10 are actually currently online.

The 2011 Tōhoku earthquake was the most devastating event in the nuclear history: a single event caused the shutdown of all 50+ reactors of a country, with much of the nuclear electricity production capacity lost for a decade - and longer.

While the country is spending billions to keep the wrecks under control.
