Fukushima Nuclear Power Plant

Japan Self-Defense Forces helicopters dropped water on the troubled No. 3 reactor of the Fukushima nuclear power plant on Thursday morning as it is feared the reactor may have released radioactive steam due to damage to its containment vessel.

Japan should quickly to prevent the disaster after fire swept a Fukushima Dai-ichi nuclear power plant , Wednesday. Fire in Japan's nuclear power plant raises threat of nuclear radiation. The incident was brought low radiation to Tokyo to push a number of people leaving the capital city and raised fears of nuclear crisis.


Tokyo police, meanwhile, plan to use a water cannon truck to attempt to cool a spent fuel rod pool in a bid to contain the disaster at the troubled Fukushima No. 1 nuclear power station in Japan. In the unprecedented move, they aim to cool the possibly overheating pool of the No. 4 reactor to prevent the discharge of highly-concentrated radioactive materials.
The building housing the No. 4 reactor suffered what appeared to be a hydrogen explosion early Tuesday following the devastating earthquake and tsunami last week. A fire also broke out Wednesday there.

In the face of the extraordinary nuclear crisis, the focus is now on how to cool the possibly overheating pools that store spent nuclear fuel rods at the No. 4 as well as No. 3 reactors.

Unless the spent fuel rods are cooled down, they could deteriorate and emit radioactive materials.
A small group of technicians, which challenged the radiation and fire, became the only group of people who remaining in the Fukushima Daiichi Nuclear Reactor.

Fear of Japanese nuclear reactor leaks have made consumers in the west coast of the United States and Canada scramble to get an antidote to radiation. But local health authorities Tuesday said fear was groundless. Authorities warned that excessive use of potassium iodide to protect against cancer will cause other medical problems for them.

Potassium iodide is a common form of salt. These substances can protect the thyroid gland from radiation and cancer caused by radioactive iodine. Potassium iodide meets the gland with non-radioactive iodine, reducing the absorption of dangerous radioactive iodine.

Japan has distributed the drug supply in the troubled area of Fukushima reactor, where the authorities are struggling to prevent the release of radiation from the reactor was damaged by the deadly earthquake on the 9 magnitude last week.
