Fukushima Daiichi Leaking Underground Lined Trenches - April 2013

Last week, problems at the crippled Fukushima Daiichi nuclear power plant reminded citizens around the world of the precarious state the decommissioning work is being conducted in.  Nuclear Regulation Authority Chairman Shunichi Tanaka was speaking to reporters on Wednesday, when he said that the plant, which relies on temporary ad-hoc cooling systems, remains highly vulnerable and that the leaks of radioactive water from underground tanks were undermining efforts to decommission the plant.

TEPCO had reported over the course of the last week that at least three of seven underground lined trenches were leaking.  TEPCO President Naomi Hirose said the cause of the leaks still could not be established, but that they were losing faith in the designs overall.   Local municipal officials began voicing strong concerns about the radioactive water leaking into the sea.  Industry Minister Toshimitsu Motegi finally stepped in this week and ordered TEPCO to stop using the underground pools.  He instructed TEPCO to accelerate the rate of construction of additional above-ground steel storage tanks and complete them by the end of May.
