Crucial Cooling Systems Restored at Fukushima Plant, Company Says

TOKYO — Vital cooling systems at the stricken Fukushima Daiichi nuclear plant were restored by Wednesday morning, more than 24 hours after a partial power failure cut cooling water to four spent fuel pools, the company that operates the plant said. The latest problem raised new fears about the continuing vulnerability of the plant, which suffered a triple meltdown two years ago and still relies on makeshift equipment.

Although the company said the latest issue was resolved long before it became a safety risk, the temporary breakdown appeared to expose a weakness in the plant’s cooling systems. The systems were hastily built by engineers during frantic attempts to regain control of overheating reactors soon after a devastating earthquake and tsunami started the crisis at the plant.

The plant operator, the Tokyo Electric Power Company, or Tepco, said a faulty switchboard appeared to be to blame in the power failure on Monday. While Tepco has backup generators at the site, it appeared to have been unprepared for a switchboard failure.

“Fukushima Daiichi still runs on makeshift equipment, and we are trying to switch to something more permanent and dependable,” a Tepco spokesman, Masayuki Ono, told reporters Tuesday as the company worked to restore the cooling systems.

The latest troubles also underscore the continuing worries about the safety of the plant, where a complex cleanup of three damaged reactors is expected to take decades. In particular, experts have warned that the makeshift cooling systems could be knocked out by another large earthquake.

Much of the concern has focused on the fuel pools, which contain far more radioactive material than the reactors and were built with less shielding, raising the specter of another large release of radioactive materials.

The four pools affected by the blackout on Monday contain more than 8,800 highly radioactive fuel rods, Tepco said. That would be enough to release far more radioactive material than the original accident in March 2011, which forced the evacuation of some 160,000 residents in northeastern Japan. Many of those evacuees still live in temporary shelters and may never be able to return home.

With the company as the only source of information, it was impossible to independently assess the conditions at the plant, which sits in a contaminated zone that is closed to the public.

On Tuesday, the company was criticized for waiting three hours before revealing the power failure to the public.

“These things are better if done quickly,” said the trade minister, Toshimitsu Motegi, whose ministry promotes the nuclear industry.

Tepco said the temporary blackout also briefly cut off electricity to the command center at the plant, though power was quickly restored.

The company also said Tuesday that the loss of cooling water was manageable because temperatures in the fuel pools would have remained at safe levels for at least four days, and the plant also has backup systems.

没关系,反正还是会再爆的
又在拖戏啦
其实福岛那事是天灾更是人祸,要在中国相关责任人早就下台了,直接责任人早就被起诉承担刑事和民事法律责任了,甚至司法程序已经结束。并且有问题的堆肯定已经用水泥封住了而不是这样互相推诿,不了了之。
看看这次能撑多久。
恢复供电了啊,好!又可以继续灌水了。
好了坏,坏了好,来来回回,反反复复,这才最有“威慑力”,呵呵。
可惜了!
是天灾,更是人祸!!
