TOKYO (AP) -- In a March 24 story about flawed projects at the Fukushima nuclear plant, The Associated Press erroneously described the spending as coming from taxpayer money allocated for the plant's cleanup. It actually was part of 350 billion yen ($3 billion) paid for by plant operator Tokyo Electric Power Co.

Japanese audit finds millions of dollars wasted in Fukushima nuclear plant cleanup

TOKYO (AP) -- Japanese government auditors say the operator of the Fukushima Dai-ichi nuclear plant has wasted about a fifth of the 350 billion yen ($3 billion) it has spent to clean up the plant after it was destroyed by a March 2011 earthquake and tsunami.
A Board of Audit report described various expensive machines and untested measures that ended in failure. It also said the cleanup work has been dominated by one group of Japanese utility, construction and electronics giants despite repeated calls for more transparency and greater access for international bidders.
Tokyo Electric Power Co. spokesman Teruaki Kobayashi said all of the equipment contributed to stabilizing the plant, even though some operated only briefly.
Some of the failures cited in the report:
FRENCH IMPORT: Among the costliest failures was a 32 billion yen ($270 million) machine made by French nuclear giant Areva SA to remove radioactive cesium from water leaking from the three wrecked reactors. The trouble-plagued machine lasted just three months and treated only 77,000 tons of water, a tiny fraction of the volume leaking every day. It has since been replaced with Japanese and American machines.
SALT REMOVAL: Sea water was used early in the crisis to cool the reactors after the normal cooling systems failed. Machines costing 18.4 billion yen ($150 million) from several companies including Hitachi GE Nuclear Energy, Toshiba Corp. and Areva were supposed to remove the salt from the contaminated water at the plant. One of the machines functioned only five days, and the longest lasted just six weeks.
SHODDY TANKS: TEPCO hurriedly built dozens of storage tanks for the contaminated water at a cost of 16 billion yen ($134 million). The shoddy tanks, using rubber seals and assembled by unskilled workers, began leaking and some water seeped into the ground and then into the ocean. The tanks are now being replaced with more durable welded ones.
GIANT UNDERGROUND POOLS: A total of 2.1 billion yen ($18 million) was spent on seven huge underground pools built by Maeda Corp. to store the contaminated water. They leaked within weeks, and the water had to be transferred to steel tanks.
UNFROZEN TRENCH: A 100 million yen ($840,000) project to contain highly contaminated water in a maintenance tunnel by freezing it failed because the water never completely froze. TEPCO subsidiary Tokyo Power Technology even threw in chunks of ice, but eventually had to pour in cement to seal the trench.
