TOKYO -- Six months since the work began, the "ice wall" has failed to produce its intended results as groundwater continues to flow in and out of damaged facilities at the Fukushima Daiichi nuclear power plant.
An encircling wall of frozen soil, created by pumping a subzero coolant through underground pipes, is getting closer to completion, the Japanese government and plant operator Tokyo Electric Power Co. Holdings reported Tuesday at a meeting of experts convened by the Ministry of Economy, Trade and Industry.
