Awwal 13, 1432, April 17, 2011, SPA -- Japanese nuclear power plant operator Tokyo Electric Power Co. (TEPCO) aims to bring radiation levels at its damaged Fukushima Daiichi facility on a downward trend in around three months, the company said on Sunday. The company also said it aims to greatly limit radiation leaks in three to six months, and that it later plans to cover the reactor building. Asia's largest utility is struggling to restore cooling functions and contain radiation leaks at its Fukushima Daiichi plant in northeast Japan after it was hit by a massive earthquake and tsunami on March 11, according to a report of REUTERS.
