Tepco starts to pump out turbine unit, Japan Times, April 19, 2011:

… Monday night, Tepco said it detected high radioactivity coming from the spent fuel pool of the No. 2 unit, indicating that either the fuel rods in the pool were damaged or steam containing radioactive materials that rose from the reactor dissolved in the pool water.

Some 160,000 becquerels per cubic cm of cesium-134, 150,000 becquerels of cesium-137 and 4,100 becquerels of radioactive iodine-131 were detected in a water sample extracted from the storing pool on Saturday.

No. 2 Reactor Spent Fuel Rods May Be Damaged, Jiji, April 19, 2011:

Tokyo Electric Power Co. said Monday that spent nuclear fuel rods at the No. 2 reactor at its crippled nuclear power plant may be damaged although damage levels have yet to be known.

The company said its examination of water in a tank connected to the spent fuel pool of the reactor at the Fukushima No. 1 plant, ravaged by the March 11 quake and tsunami, found 4,100 becquerels of radioactive iodine per cubic centimeter and 4,000 to 160,000 becquerels of radioactive cesium.

The radioactive cesium levels are extremely high, company official Junichi Matsumoto said. The company believes the levels, compared with data on leaks from the reactor vessel, indicate that spent fuel rods have been exposed and damaged. The spent fuel pool contains 615 fuel assemblies.

However, the industry ministry’s Nuclear and Industrial Safety Agency believes the detected radioactive materials are likely to have leaked from the reactor vessel.

The agency explained that it is implausible to associate the high concentration of iodine-131, whose half-life is short, with spent nuclear fuel rods, which are stored for a long time.

“A sample of water taken Tuesday [from No. 4′s spent fuel pool] contained 220 becquerels of iodine-131 per cubic centimeter. That compares with a level of just 0.01 becquerels or less for normal spent fuel pools.” –Wall Street Journal, April 14

“The company said a newly analysis indicated the damage to some fuel rods in the No. 4 unit’s spent nuclear fuel pool, as it detected higher levels of radioactive iodine-131, cesium-134 and cesium-137 than normal. Radioactive iodine-131 amounting to 220 becquerels per cubic centimeter, cesium-134 of 88 becquerels and cesium-137 of 93 becquerels were detected in the No. 4 unit’s spent nuclear fuel pool water, according to the TEPCO. Those Radioactive materials are generated by nuclear fission.” – International Business Times, April 14

    Its all onsite, and defore lokal, and just confirms a “leak”.

    The overall picture is still missing.
    The magnitute of the spreading and What is there, is missing, or at best, cherrypicing.

    And dont forgett, the explosion on rea.3.
    Where is the Plutonium, its like is waporised, and that Not the case.

    • informed

      Weaponed Plutonium is mix with the regular plutonium from 25 to 60% in the fuel rods, the first one was fired up in Aug 2010, it was shipments to them in April that year from France. GOGGLE IT !

    Put your head between your legs and kiss you butt goodby.

    This is a TINY bit of what is to come in the next couple of weeks.

    Do not worry about it. There is nothing anyone can now do about it.

    Goodbye General Electric & the N R C of the USA. Your safe design is dropping radioactive poison all over the earth. You WILL DIE with the rest of us.

    Gunderson, Fairewinds.com, April 18, 2011: “I don’t really think that the mainstream media has addressed that: that Unit 2 is the cause of all of this radioactive pollution [going] out into the ocean because its containment doesn’t have integrity, and its reactor doesn’t have integrity, so whatever water is going in the top is going out the bottom, through the containment, and into the surrounding soils. It’s the biggest concern.”
