[...] Tepco said it doesn’t think that water has flowed into the sea but can’t say for sure. Some of the flooded reactor basements are similarly too hot to approach, and it is still not clear where the melted fuel cores are, or in what state.
“In the future there might be even more heavily contaminated water coming through,” said Atsunao Marui, head of the groundwater research group at Japan’s National Institute of Advanced Industrial Science and Technology and a member of a blue-ribbon panel set up in May to figure out ways of managing the radioactive water. “It’s important to think of the worst-case scenario.”
Mr. Marui and others say the biggest reason for the scramble now is that Tepco—and the government bodies that oversee it—weren’t planning far enough ahead and waited too long to respond to problems they should have seen coming long ago.
