Radioactive Cesium still being found at Japanese waste incenerators!

A few months ago it was reported that waste incinerators (which is how Japan handles its trash) were finding high levels of radiation in the ash of the burned trash.  The disaster at Fukushima Daiichi was blamed.

Today, waste incinerators as far south as Tokyo are still emitting cesium through their exhaust stacks.  One incinerator in Edogawa ward registered 9,740 becquerels of cesium per kilogram!  The incinerator handles only household trash.  This is an indicator that cesium is still being spewed into the air, and it’s settling as far south as Tokyo.

Strontium 90 found in Pacific seabed!

For the first time strontium 89 and 90 have been found on the seabed near the Fukushima Daiichi nuclear plant.

Tokyo Electric Power Company tested the soil at the bottom of the Pacific Ocean, on 02 and 03 June 2011, at locations 20 kilometers (12 miles) from the nuke plant.

While this is the first time strontium has been found in the seabed, it is not the first time it’s been found in the water.

Corporate & Government Incompetence: Nebraska flood knocks out power to Nuclear Plant, no thanks to workers not paying attention

26 June 2011, an accident at the Fort Calhoun nuclear power plant resulting in the expanding Missouri River flooding into the compound.  The water hit the nuke plant’s electrical transformers, cutting off power.

Electricity is still needed to keep the spent fuel pools cool.  Plant officials say they are now running on back up generators.

Forth Calhoun officials ordered the installation of a water filled artificial levee (berm).  The Nuclear Regulatory Commission did not approve the artificial levee.  At about 1:25 am, 26 June, workers broke the water filled berm, allowing the Missouri River to flood in.

This natural disaster is the latest bad news for the Fort Calhoun nuke plant.  In April plans to refuel its reactors were halted, over concerns of flooding by the Missouri River.  Then, on 07 June, a fire broke out in one of the reactor control rooms.  An inspection two years ago revealed that plant operators were not properly prepared for a flood.

Boric Acid to be Poured into Fukushima Daiichi Reator 3

After several months of spewing radiation all over northern Japan, Tokyo Electric Power Company is finally going to use boric acid on one of the Fukushima Daiichi reactors.

Actually TEPCo is pouring a borci acid/water mix into the spent fuel pool above Reactor 3.  By Monday evening, 27 June 2011, they will have used 90 tons of the mixture.

What is happening in the fuel pool is that radioactive concrete debris, from the hydrogen explosions, were stored in the fuel pool.  TEPCo has discovered that calcium hydrate from the concrete debris has made the water highly corrosive, increasing the chances of structural failure of the fuel pool.  They fear the racks holding the spent fuel rods will collapse, causing the rods to crash into each other, thus causing “re-criticality”.

Doctors say don’t eat Japanese vegetables, they’re radioactive!

A group of doctors tested people living in the Fukushima Prefecture of Japan.  That’s where the damaged Fukushima Daiichi nuclear plant is.  They discovered people living outside the evacuation zones are internally contaminated with radiation.

The doctors tested people in two cities; Iitate Village and Kawamata Town.  They are about 40 kilometers (24 miles) from the nuclear plant.  They tested their urine, to check for internal radiation contamination.  They found the people have three times what is considered normal exposure for one year.

The doctors are telling the people of Fukushima Prefecture to stop eating the locally grown vegetables.

Corporate Incompetence: TEPCo shuts off wrong valves!

Yesterday I speculated that Tokyo Electric Power Company probably installed their water radiation filters backwards.  Today NHK reporting that incorrect settings of the system are the cause of TEPCo’s problems.

At least twice TEPCo had to stop their decontamination of water, at Fukushima Daiichi, because they were getting the reverse effect; an increase in radiation levels in the water.  Another time they stopped because they broke a water pump.

It turns out all those problems were caused by the incorrect setting of valves.  The result was that less than half of the filter chambers were being used.  TEPCo blames their throwaway workers for misunderstanding the “open” and “shut” indicators on the U.S. designed system!

Government & Corporate Incompetence: 6 out of 10 towns got no Nuclear evacuation order after 11 March!

10 cities around the Fukushima Daiichi nuclear power plant were supposed to get evacuation orders immediately after the nuclear disaster, following the 11 March 2011 natural disasters.  Only four of those cities got the evacuation order.

The national government of Japan, and the prefectural government of Fukushima have apologized for the break down in communication.

Also, Tokyo Electric Power Company was responsible for notifying five nearby cities/towns of the nuclear disaster, but evidence shows that was a major ‘F’ up.  One town got 80 faxes of the notification, while another town got zero notification!

This major breakdown in communication, by TEPCo and government,  resulted in massive confusion about what people were supposed to do.

Corporate Incompetence: Radiation decontamination fails for the third time, reactor temperatures rising!

For the third time Tokyo Electric Power Company stopped decontamination of radioactive water at Fukushima Daiichi.  This time radiation levels on the outflow side of the massive water filter skyrocketed, instead of going down.

The idea is that water coming out of the decontamination unit would have less radiation.  The opposite is happening.  When TEPCo re-started the operation on Tuesday radiation levels were at 3 millisieverts per hour, by Wednesday, 22 June 2011, the levels hit 15 millisieverts per hour.

The result is that not only has decontamination efforts stopped, but TEPCo says it can not inject anymore water to cool reactors, for fear of massive flooding of contaminated water out of the reactors (even more than what is leaking out now).  Already the temperatures in Reactor 3 are rising.

Japanese media says the water decontamination unit was designed in the United States.  Could it be possible that the decontamination chambers are backwards?  Don’t laugh, here in Idaho in the late 1990s, on the Shoshone-Bannock Reservation boil order after boil order were being issued.  Finally, after tribal officials investigated their new water treatment system, it was discovered that all the filters were in backwards.

Government & Corporate Incompetence: Radioactive Tritium leaking from U.S. nuclear reactors

A year long study of U.S. government documents, by the Associated Press, has revealed that radioactive tritium is leaking into groundwater.

Documents show that at least 48 nuclear plants in the U.S. have, or are, leaking tritium.  Tritium is a radioactive form of hydrogen.  The report comes from the Nuclear Regulatory Commission.

At least 37 of those leaks exceeded government safe levels for drinking water.

It’s not just tritium that’s leaking from U.S. nuclear reactors; cesium and strontium are also leaking.

Strontium 90 was found leaking at Indian Point nuke plant north of New york City.

Cesium 137 leaked from Fort Calhoun nuke plant in Nebraska.  By the way, that reactor was just shut down because the Missouri River is flooding it.

There’s much more about the leaks from U.S. nuke plants in the AP report.  Maybe this explains the increase in cancer rates over the past decades?

Like I said before: Everyone living near nuclear reactors in the United States should make plans to get away.

Corporate Incompetence: Once again, TEPCo stops radiation decontamination

For the second time Tokyo Electric Power Company has stopped decontamination of water at it’s Fukushima Daiichi nuclear plant, this time they broke a water pump.

The first time was because the radiation levels were much higher than first thought, and the water decontamination system wasn’t set up to handle it.  This time TEPCo officials think it’s because they tried to force too much water through, and broke a water pump.
