Pretty sure Fukushima Daichi is disabled. It was a 7 on the INES. I think the Fukushima Daini plant might still be active, but that’s a different plant, several miles away.Fukashima still is producing power.
As for the severity of the accident, I think they’re still trying to sort that out. How much cesium-137 is still leaking out into the ocean? There’s also a marked increase in the number of kids in Fukushima Prefecture with thyroid growths and thyroid cancers as compared to other areas, no doubt from radioiodines that were released after the accident.
