Akhir 24, 1432, March 29, 2011, SPA -- Workers at the crippled Fukushima Daiichi nuclear plant faced a difficult balancing act Tuesday as they struggled to keep reactors cool and prevent radioactive water from leaking into the ocean. Water has been a key weapon in the battle to stave off a meltdown at the facility since a March 11 earthquake and tsunami knocked out cooling systems. But officials say there's a flip side to pumping and spraying tons of water to keep radioactive fuel from overheating: the water has to go somewhere. The discovery of contaminated water in a maintenance tunnel has sparked fresh concerns about the possibility of additional radiation leaking from the plant, CNN reported. "Now the focus is how to... remove the water and contain it safely," Chief Cabinet Secretary Yukio Edano told reporters Tuesday.
