Rats! Anti-rodent work shuts down Fukushima nuclear plant's cooling system

Attempts
stop rats getting inside a reactor at the Fukushima Daiichi nuclear
power plant led to a cooling system shutdown. Debris on the fuel rack in
a spent-fuel pool is seen in this handout photograph taken in
mid-February.
Power for the cooling system for a storage pool for fuel was restored after a two-hour break at reactor No. 3, and there was no immediate danger from the breakdown, according to Tokyo Electric Power Co., the utility that operates Fukushima Daiichi in northeastern Japan.

A
dead rat is seen near a temporary switchboard used to supply power to
cooling systems at three fuel pools in the Fukushima facility in this
handout photograph taken on March 20.
A dead rat found near a switchboard was suspected of the power outage last month that led to a cooling system not working for two days at the plant.
Nuclear Regulation Authority spokesman Takahiro Sakuma said an alarm went off in the afternoon about the latest problem at reactor No. 3.
Multiple meltdowns
The cooling system can be turned off for two weeks before temperatures approach dangerous levels at the spent fuel storage pools.
But if the water runs dry, the fuel rods, even spent ones, will spew enormous levels of radiation.
The plant went into multiple meltdowns after the March 2011 tsunami damaged backup generators and all cooling systems failed, including those for the reactors.
Journalists
have been given a rare glimpse inside Japan's Fukushima Daiichi nuclear
power plant, which was crippled in the 9-magnitude earthquake and
tsunami that hit the country two years ago. NBC News' Arata Yamamoto
reports.
The plant is being decommissioned, but continues to have glitches.Fears are growing about the safety of nuclear plants, and people have periodically staged streets protests that are rare in Japan.
Only two of the nation's 50 working power plants are up, and the government is running beefed up safety checks on the plants, including scrutinizing quake faults right below or near the plants.
Shinzo Abe, who became prime minister about three months ago, has expressed a desire to restart nuclear plants.
Japan lacks natural resources and relied on nuclear energy for about a third of its electricity needs prior to March 2011. Energy imports have soared over the last two years, putting a strain on the economy.

The problem I could see with rats is that they are a part of the food chain and will be eaten by other predators up the food chain in that area like hawks and other predatory animals. So, those animals will carry radation too. Also, on one report today they said that they found a fish off of Fukshima there with 7,400 times the safe level of radiation in it's flesh. So, as these 7,400 times the safe level of radiation fish are eaten by predator fish like sharks, Tuna and others who travel all over the ocean the radiation is spreading through their bodies all over the Pacific Ocean, especially if you study the migration patterns of predator fish and dolphins.
