Japan declares 'nuclear emergency' after quake - PART 2

a reply to: Purplechive

Gotta love these press releases...

Tokyo Electric Power Company has been investigating the damage to the reactor's containment vessel... a robotic investigation detected flows of contaminated water last November... Utility officials believe water from the damaged pipe is flowing to the lower part of the vessel... They say they will study ways to stop the leak... Identifying the specific locations of the water leakage is important... Officials say they will now investigate the suppression chamber and other parts of the Number 2 reactor

That they don't know every available square inch of all the reactors 'by now' is ridiculous - they're going to 'study' ways to stop the leak? Don't they already know how to deal with nuclear melt downs and leaks? Leaks flow downhill... there's a revelation. Identifying the location of the leaks is important... no kidding! And now they'll investigate other parts of the number 2 reactor... We're in so much doo doo from these clowns. Unit 2 is the one referred to in that video where the clouds disappear as they pass over it. Too radioactive for people but nothing to worry about folks...

Does anyone know if any (or all) of these units could still be throwing up hot particles or would they have all/mostly taken off with the explosions?

More 2011 Japan tsunami debris washing ashore

Wednesday, May 28, 2014, 11:51 AM - More than three years after a catastrophic earthquake and tsunami killed thousands in Japan, debris from the disaster is still making its way to American shores.

Barnacle-encrusted boats and other items have been showing up on the beach in southwest Washington state.

It would be nice if someone had geiger counters to check these boats and tsunami debris with... like the government or environmental departments... I wonder what they do all day while ignoring all this stuff?

It is highly recommended that everyone watch this!!

Thanks for posting it. 250,000 tons of bagged, radioactive dirt laying around and Tepco has no time to answer questions. Yes, I'm sure they're full time busy covering their butts, er I mean solving the problems. *sigh*

Does anyone know why they can't recycle the water being used to cool it instead of continually contaminating fresh water?

a reply to: wishes

I have wondered that myself..,, I assume that after being used so many times, it would become radioactive to the point where you couldn't even get near it.

There is a known natural problem with storing the contaminated water.......when a radionuclide bounces off a steel wall, like those lining the tanks.... they generate gamma rays outside of the tanks.... I know a while back there was an issue with this, the gamma rays were pushing the radioactivity in the area around the tanks to more than 8 times what is around the rest of the plant.

I think that's why they can't keep using the same water over and over... the gamma rays would increase in the tank area exponential to the amount of radiation in the water that is being stored...

It was already bad with the water they have stored now.... if they started storing water higher in readings, then it would be logical to assume that the gamma rays would increase as well.

I cant remember the term to describe the gamma rays being generated by strontium and cesium etc bouncing off of steel walls, but it is somewhere in one of these Fukushima threads.

well if for nothing else at least check for,,


but beware, it just may very well be radioactive,,
cause we cant see radiation,,


and contrary too popular opininion,,what u can't see can also hurt u.

BREMSSTRAHLUNG is the word I was looking for about gamma rays being emitted when Cesium 137 or Strontium 90 radionuclides encounter a steel wall. It generates gamma rays outside of the water tanks. This has been a problem at Fukushima for some time now and that would be the reason why they cant keep using contaminated water over and over again for cooling purposes.

Thank you for the video...........If you are living in Japan and care about your personal health and the health of your children.........WAKE UP.



This is going to be harsh but it is a fact. The foolish pride the Japanese hold so dear is going to kill countless people. How many children will never be born? How many lives will end early? How many people will suffer with cancer?



Foolish......Foolish people. But they still trust what they are told because of pride.

Well here's more cheery news...

Tepco dumps groundwater near Fukushima into Pacific ocean
Updated 22 May 2014, 15:34 AEST

Tepco says the groundwater being dumped into the sea flowed from nearby hills and met radiation safety levels. The controversial move followed an agreement with local fishermen.

NRA to approve frozen wall work at Fukushima plant

The Japanese government and Tokyo Electric Power Company may start construction as soon as next month of underground frozen soil walls at the Fukushima Daiichi nuclear power plant. The measure is considered key to preventing groundwater from entering the damaged facility and becoming contaminated with radioactivity. The Nuclear Regulation Authority reviewed the project at a meeting in Tokyo on Monday. Officials from TEPCO said their estimates show the ground around the Number 1 to Number 4 reactors would sink as much as 16 millimeters after the underground walls are built. They said this would not be a problem because the degree of sinkage is smaller than the limit set for nuclear power plants.

Note the accepted notion of the site 'sinking' 16 millimeters because it's an acceptable limit set for nuclear power plants - presumably a limit set for nuclear power plants that are 'whole' and 'in good standing'.... is like spitting on a forest fire - or - throwing gas on it depending if sinking makes any difference to the already leaning structures full of fuel rods, etc. etc. etc.

I am hoping that that little video was not the end all of their research but really ............ it would not surprise me one bit if it was! This is Tepco after all.

There are all sorts of other factors like the fact that water is heavy and has a lot of power to push such a frozen wall out of the way. Then there is the need to stop the incoming water from thawing the nice wall. One crack and the water will pour through. What happens to the water when it hits the wall, will it just bubble to the surface and flood over the wall.

Lots of things can go wrong. Lots will.

Unit 2 PCV Temp Readings Dropped From Data

Did anyone hear of an announcement as to why the PCV readings were dropped? They have fried so many sensors in Unit 2.

On May 14 and prior they had two PCV readings:

Suddenly on May 15 the PCV readings were removed:

Unit 2: Where is the Water?

TEPCO: Water in reactor half expected level
Officials with the operator of the damaged Fukushima Daiichi nuclear plant say the water level inside the No.2 reactor's containment vessel is about half what they had estimated.

Workers with Tokyo Electric Power Company used robotic probes to measure the level and temperature of cooling water inside the vessel.

They found the water was around 30 centimeters deep. They had estimated it would be 60 centimeters, based on images captured by an endoscope 2 years ago.

The water was around 35 degrees Celsius.

TEPCO officials say this suggests the melted fuel is being kept cool. But they say they don't know whether the fuel is entirely submerged.

They say they suspect water is leaking into a unit called a suppression chamber via a pipe that's around the same height as the water. They believe it's then flowing out of the reactor building through holes in the chamber.

TEPCO is planning to plug the holes and add water to the containment vessel before removing fuel from the reactor.

At least we know where that core is. Can't say as much for the others.

The cores of Reactors 1-3 are still undergoing fission and the process is creating hundreds of different isotopes.
