The utility company that operated the Fukushima Daiichi nuclear plant in Japan — the one that went into triple meltdown after the enormous 2011 earthquake and tsunami — has released some jaw-dropping figures.
The radiation level in the containment vessel of reactor 2 has reached as high as 530 sieverts per hour, Tokyo Electric Power Co. — or Tepco, as it’s known — said last week. This far exceeds the previous high of 73 sieverts per hour recorded at the reactor following the March 2011 disaster.
That was the world’s worst nuclear disaster since the one at Chernobyl, in Ukraine, in 1986. Almost 16,000 people were killed along Japan’s northeastern coast in the tsunami, and 160,000 more lost their homes and livelihoods. The cleanup is taking much longer than expected.
