300,000 tons of radioactive water at Fukushima, and still growing

As of May 7, the Japan Times reported that TEPCO had installed 290 huge storage talks at Fukushima to hold more than 78 million gallons (290,000 tons) of radioactive water, with another 25 million gallons still uncollected.  Fukushima is generating an estimated 100,000-plus gallons (400 tons) of radioactive water every day

 TEPCO estimates that groundwater is entering the complex at a rate of at least 54,000 gallons per day.

Fukushima 2013: “Remaining Radioactive Mass”, “Dangerous Leaking Radioactive Water”, All Four Reactors are “Getting Worse” By William Boardman Global Research, July 11, 2013 The first thing to know about the danger from the radioactive mass remaining on site in the three reactors that melted down at Fukushima is that nobody knows how much radioactive material there is, nobody knows how much uranium and plutonium it contains, and nobody knows how to make it safe — so no one knows how great the continuing danger is.

In order to prevent nuclear material from being diverted to use in weapons, the International Atomic Energy Agency of the U.N. requires each country to report regularly on the volume of nuclear materials in its nuclear power plants. At Fukushima, this is currently impossible with the cores of the three reactors that melted down.

Diversion of this material to weapons use is not a problem at the moment, since the level of radioactivity is high enough to kill anyone who comes close to it, which is why it hasn’t been moved. On the other hand, it is necessary to move it in order to measure it, and even if it was movable now, the technology to measure it does not yet exist.

Cooling the Cores Keeps Them from Burning, but Creates Radioactive Water

The Japanese Atomic Energy Agency has joined with the U.S. to develop the necessary new technology, which it hopes to begin using within a decade. The Japanese agency calls this collaboration the “world’s first” attempt at such technology, since a similar U.S. initiative to measure the melted core from the 1979 Three Mile Island accident failed.

Watertight fuel pools are used effectively at nuclear power plants around the world, including Fukushima before the March 2011 earthquake and tsunami.  Now the reactor structures are no longer watertight and TEPCO has pumped millions of gallons of fresh and “least contaminated” into the structures since then, and continues to do so.

Radioactive Water Is Dangerous, And It Has To Go Somewhere

 Water used to cool nuclear fuel and waste becomes radioactive itself, as does the groundwater that infiltrates the structures. This radioactive water continues to reach the Pacific Ocean in varying quantities, as TEPCO attempts to keep it in check.

As of May 7, the Japan Times reported that TEPCO had installed 290 huge storage talks at Fukushima to hold more than 78 million gallons (290,000 tons) of radioactive water, with another 25 million gallons still uncollected.  Fukushima is generating an estimated 100,000-plus gallons (400 tons) of radioactive water every day

TEPCO estimates that groundwater is entering the complex at a rate of at least 54,000 gallons per day. In May 2012, the Japanese government ordered TEPCO to build a wall deep into the ground around the plant to keep groundwater out, a plan that might become operational by early 2015.

TEPCO is expanding its storage capacity to about 1.9 billion gallons by clearing forest and other areas around the compound.  While this would probably suffice for another three years, the site is running out of storage space. Additionally, some of the storage tanks have begun to leak and contaminated water is leaking into the soil.http://www.globalresearch.ca/fukushima-2013-remaining-radioactive-mass-dangerous-leaking-radioactive-water-all-four-reactors-are-getting-worse/5342466
