Tokyo Electric Power Company has been trying to cool the nuclear fuel rods at the Fukushima Dai Ichi nucler plant. They began to first inject sea water in an attempt to cool the rods and control a possible Chernobyl melt-down of the reactor core. Someone must have pointed out that flooding the metal containment vessel with highly corrosive sea water probably wasn't a good thing. They then switched to pumping in fresh water. The question that has been on my mind, what are they going to do with all of that radioactive water?
The nuclear power plant was not designed to be flood with water. The radioactive water will leech into the group or spillout of the plant and get into the ocean and surrounding environment. There does not seem to be a good solution. At least with Chernobyl, it was land locked. Radioactive material could be more easily contained that with the Dai Ichi plant that even the smallest spill will get into the ocean. Japan and most of the pacific get their protein from seafood. Contaminated oceans mean shortages of food as well as a devastating impact to the economy.
