No quick fix seen at Japan's nuclear plant
FUKUSHIMA,[link widoczny dla zalogowanych], Japan – Officials raced Monday to restore electricity to Japan's leaking nuclear plant, but getting the power flowing will hardly be the end of their battle: With its mangled machinery and partly melted reactor cores, bringing the complex under control is a monstrous job.
Restoring the power to all six units at the tsunami-damaged complex is key, because it will,[link widoczny dla zalogowanych], in theory, power up the maze of motors, valves and switches that help deliver cooling water to the overheated reactor cores and spent fuel pools that are leaking radiation.
In another setback,[link widoczny dla zalogowanych], the plant's operator said Monday it had just discovered that some of the cooling system's key pumps at the complex's troubled Unit 2 are no longer functional — meaning replacements have to be brought in. Tokyo Electric Power Co. said it had placed emergency orders for new pumps,[link widoczny dla zalogowanych], but how long it would take for them to arrive was unclear.
If officials can get the power turned on,Japanese officials will test food, seawater to det,[link widoczny dla zalogowanych], get the replacement pumps working and get enough seawater into the reactors and spent fuel pools, it would only take a day to bring the temperatures back to a safe, cooling stage,[link widoczny dla zalogowanych], said Ryohei Shiomi, an official with the Nuclear and Industrial Safety Agency.
And if not?
