The Fukushima No. 1 nuclear crisis has been raging for a month, shattering Japan's reputation as a safe, advanced nation and attractive tourist destination.

The situation is so bad that experts and government officials aren't even sure how many months it will take to bring the plant under control.

Tokyo Electric Power Co. urgently needs to repair the plant's damaged cooling systems or even construct a whole new external plant to lower the temperature of the reactors to less than 100 degrees to stabilize the blazing fuel rods inside.
