Entire post from NHK below- with not one single mention of the ice wall. Instead- the regulators think TEPCO really should DO something about the problem - since - they haven't. They are doing a study, though! Thank goodness. Oh, and this press release points out they are still pumping water into the melted down reactors to cool them. And the water then goes - where? They're not sure.
"TEPCO urged to cut risk of radioactive water leak
"Japan's nuclear regulator has urged the operator of the crippled Fukushima Daiichi nuclear power plant to reduce the risk of leaking of highly radioactive water from the facility into the sea, in case of another tsunami.
"About 60,000 tons of such water is believed to have pooled in reactor buildings at the plant. The operator, Tokyo Electric Power Company, or TEPCO, is injecting water into the buildings to cool melted nuclear fuel, and groundwater is flowing into their basements.
"The Nuclear Regulation Authority instructed TEPCO at a meeting on Tuesday to urgently study measures to lower the amount and radiation levels of the water.
"The authority proposed 2 measures to TEPCO. One is building more tanks to store the water, even though the plant has about one thousand tanks. The other is treating the water using a system designed to filter out radioactive material, and circulating the water in a cooling system.
"NRA member Toyoshi Fuketa said the utility cannot keep the water in the buildings forever. He said TEPCO should handle the water problem either along with that of other radioactive water or first of all.
"Following the NRA's instruction, TEPCO is to report the results of its study at a meeting next month or later."
