Yes, Toxic Water From Fukushima Spreads to the Pacific Ocean

A storage tank at the site of the Fukushima nuclear reactors has sprung a “significant” leak and is now pouring out toxic water. Approximately 300 tons of radioactive water have already gone into the ground from where they can seep into the nearby Pacific Ocean.

As of Wednesday, Japan’s nuclear agency has upgraded the severity level of the leak from one to three on the International Atomic Energy Agency (IAEA). Eight would be considered the gravest leak; each single-digit increase on the IAEA represents a tenfold increase in the severity of radiation released.

The leak in the Fukushima storage tank is the severest warning given the wrecked power plant since a powerful tsunami and a magnitude 9.0 earthquake occurred in 2011. The resulting meltdown of three of the plant’s six reactors was ranked the most severe possible, on a par with the 1986 Chernobyl disaster.

A single puddle of water from the leaking storage tank is now emitting 100 millisieverts an hour of radiation. That is, the water is so contaminated that, if you were standing 50 centimeters away from it, after one hour you’d be exposed to five times the dose limit for Japanese workers.

Those workers, whose task is to contain the leak and remove the remaining water from the tank, certainly face huge risks in cleaning up the site. After ten hours in proximity to the contaminated water (which they’re trying to contain with sandbags), they are may develop radiation sickness, become nauseous and experience a drop in their white blood cells.

Teams of workers must constantly be rotated and most of the contaminated water — stored in some 1,000 tanks built distressingly close (about 500 yards) to the shoreline – has probably already seeped into the ground, according to the BBC.

Just the day before, Tepco, the plant’s operator, had said the leak was far less severe. The company has yet to identify what the cause of the leak was and also says that is no evidence that any water has made its way into the ocean. Such statements from Tepco are hardly reassuring. Back in July, the utility admitted for the first time that groundwater full of radioactive isotypes has been making its way into the ocean.

The leaking water tank is yet another sign of Tepco’s struggle to clean-up the site. The utility  has been pumping massive amounts of water into the plant to cool down the nuclear cores but, because the reactors’ containment vessels were damaged in the 2011 meltdown, these are unable to contain that water, Ars Technica says. The recent leak from a storage tank is only compounding the amount of toxic water that is spreading into the environment.

Japan’s Prime Minister, Shinzo Abe, is a supporter of nuclear energy. It is only recently that he has said he has lost confidence in Tepco’s ability to handle the situation at Fukushima and said that Japanese government will now intervene to help Tepco stop the leaks.

It’s an announcement — made amid mounting public anger over the leaks and Korea’s Asiana Airlines canceling four chartered flights between Seoul and Fukushima in October out of concerns about the radiation – that is arguably too little and too late in view of the hot and leaky mess that remains in Fukushima. After two years, Ars Technica underscores, we still know very little about the state of the site, including whether all the nuclear fuel has been shut down.

“All signs point to a significant contamination of the groundwater at the site with radioactive cesium,” says Ars Technica. As one cesium isotope has a half-life of 30 years, the contamination is more than likely to be a very long-term problem. Authorities say that radioactive levels in seafood from the immediate area of Fukushima “currently pose no health risks” but the chances for radioactivity spreading throughout the food chain increase the longer the contamination exists. Leaks like the most recent one in the storage tank are only making a very bad situation worse and worse.

I can't help but think that this is the sweet revenge of the planet earth and its oceans on Japan for poaching our whales, finning sharks, acting as the illegal smuggling center for poached ivory, sending their criminal Mitsubishi companies to cut down Asia's forests, setting up towns for the vicious practice of shark finning, murdering the most intelligent animal the dolphin for their unlimited greed, raping the oceans of fish species, ad nauseum. Earthquake/Tsunamis, Fukishima radiation, huge typhoons and floods, the anger of the oceans will destroy Japan for their immoral actions.

sad news but thanks for sharing

The principle source of energy on earth is the Sun, and we mostly fail to use it because of capitalism. The same is true for the energy in ocean waves. Why don't people stop viewing capitalism as an unmixed blessing and really address its shortcomings and failings while we are still alive on earth?

Gloria H, the news depresses me too. The only thing we can do is push for smarter policies and stop viewing and listening to the news for awhile and give ourselves a chance to recover.

Thanks to the careless siting of nuclear power stations on coastlines in the US and Japan, seawater is now contaminated. Thank God, San Onofre in California won't be going back online. I hope nuclear advocates will stop pretending their favored power source is harmless and push for some real safety measures.

They have the nuke plants and we have BP working 24/7 to rid sealife, and maybe ALL life as we know it.
We're doomed. I'm so depressed by the news I'd go out and eat worms but I'll be Monsanto has genetically altered them.

Original proponents of nuclear energy wouldn't accept financial responsibility for nuclear accidents were less likely than two airliners colliding in mid air. I guess we better not fly any more. Poor Japanese. Fish are a favorite traditional food item for them as well as many others who have come to love sushi and sashimi. Mass rallies against nuclear plants were ignored by their government and were too late anyway. At my age, I won't be around to see if humans still exist in the year 3000.

Our Government Slaps them on the wrist for dumping billions of gallons of toxic waste into OUR OCEANS. Why are we surprised now and why didn't anyone give a shit about it when it first started?

It's long past time to put solar power systems on every home. buissiness, warehouse, vacant lot, brownfield, or former landfill in America. Nuclear power is not safe, expensive, uses too much valuable water, and could become a terrorist target. Imagine if a suicide terrorist bomber could fly a plane into a reactor. The threat from terrorist or environmental damage from earthquakes or storms is too great. We don't have the technology to store deadly highly radioactive nuclear waste for 10,000 years. For the astronomical price of one nuclear reactor, we could decentralize solar power, and put it on every home, business, warehouse, or vacant lot in the normal electric utility service area. The price of solar power is going down, and nuclear is going up. This should be national priority, to close all dangerous nuclear power plants and replace them with decentralized solar power.
