Work to dismantle the upper half of an exhaust stack at the crippled Fukushima No. 1 nuclear power plant finished on April 29, the first time a structure highly contaminated by radiation was dismantled at the plant. The chimney, which is 120 meters tall and about 3 meters in diameter, was used for the No. 1 and No. 2 reactors of the plant, operated by Tokyo Electric Power Co. On the morning of April 29, workers spent an hour to lower sliced parts of the stack to the ground from a height of about 60 meters. With its upper half removed, the chimney now stands 59 meters high.
