Well, the truth is finally emerging. The Fukushima reactors were critically wounded, some possibly fatally, into meltdown BEFORE the tsunami hit! The old and rickety cooling piping had been the subject of numerous repair orders, and was literally falling off the walls during the earthquake. It looks like the the tsunami was a coup de gras that ENSURED q00% failure of ALL the cores and cooling ponds into meltdown, some meltdowns would likely have occurred WITHOUT the tsunami. This indicts the idea that only this terrible combination is what caused the nuclear plant meltdown failures, and that plants not subject to tsunami dangers are "just fine". We now see even MORE lies, more false assurances to the public, and the continued potential for hundreds of thousands or millions more refugees from future catastrophic nuclear plant failures from earthquakes, attacks, or operator errors. http://www.independent.co.uk/news/w...truth-behind-fukushimas-meltdown-2338819.html
I always knew Japan had issues with corporate corruption, but this looks far worse than I would have expected.
Unfortunately corporate corruption isn't just limited to Japan. Corporations are meant to make as much profit as possible and making nuclear reactors as safe as possible would make these profits melt. So would adequate insurance of the risks of a nuclear meltdown. This is why corporations shouldn't be allowed to run nuclear reactors.
I'm a little dubious of claims the plants were in melt down type trouble before the tsunami. They're pumping water into those reactors through some piping now. So something must have held. And the plants would only need one operational train of emergency cooling water. Also only the pipes related to emergency core cooling would be designed to the higher standards. One would expect piping not related to that to be breaking all over the plant including pipes that might normally carry cooling water so that might be what workers saw. I wonder if they successfully recovered instrument recordings of the disaster up until power was lost. Those should be able to indicate how the plants were doing prior to then.
No, they are NOT pumping water into those reactors using the cooling piping now. ALL the "cooling pipes", "emergency" or not (whatever that could be), are trash. They are pouring water, fairly inefficiently, onto the reactor shrouds, generating additional huge quantities of radioactive water. Essentially they are still spraying water onto the reactors like we saw with the fire hoses, except now the pipes are fixes in place. A few weeks ago they switched from sea water to fresh water which will reduce, a little, the quantity of secondary radioactive particle emitted into the air, water and surrounding land. They have recovered nothing from much of the plant. Huge sections are far too radioactive for anyone to EVER enter. The high radioactivity is making anything inside cooked and non-usable anyway. But any cooling pipes in the cores would be pointless now anyway! The radioactive fuel has melted down and to or through the bottom of the containments. It is the fuel rod pools they are trying to keep from going critical, which may occur. Massive increases in radiative emissions are still likely. http://crisisjones.wordpress.com/20...-reactor-cooling-was-from-outside-the-shroud/
Even based on the article that's just speculation. I'm pretty sure that's where cooling water is supposed to go. Meaning where it does go when things are going right. The point of the shroud being to deflect the water coming in down underneath the fuel and up through it from below. The hoses are going to the piping which would be needed to get water to a shroud. In principle I guess one could run a hose up to where a shattered pipe is, but that would be way to radioactive unless the break was far from the core. CNN or whatever had pics of them in the control rooms, which are in a different though adjactent buildings from the reactors. I'd expect the recordings to be there. I suppose I don't know what recording method they're using. But paper ought to be fine if the rooms didn't flood, and I'd expect magnetic recording media to be fairly radiation resistant. At least the magnetic portions if not the supporting circuitry. I think they've got the spent fuel pools pretty well under control right now, that's not nearly so hard a task. And either way you still need to keep cooling water in with whatever is left of those corse. Sounds like they're looking for a way to dump water in from above. Which I suppose makes sense. Melting fuel might have plugged up the usual pathways for water coming in from the bottom.
The article is describing the destruction that occurred BEFORE the tsunami. Dewtruction that is well known and obvious, but supposedly happened AFTER the tsunami and AFTER the plant explosions. You do know two of the plants blew up, right?, from probable steam and hydrogen/oxygen explosions from water broken down to its basic elements by the melting-down cores. Cooling by pouring water on the reactor shroud is like cooling your car engine by pouring water on your car hood after your radiator and all the pipes that carry the normal cooling water throughout your engine block have broken. Not effective. Particular several of these cores have melted down through the bottom of the reactors' stell AND concrete containments and now appear to be in the earth. The fact that the still fissioning cores have completely left the building is the subject of this video and the testimony. The power died in the control rooms very quickly after the tsunami hit, that is why the cooling pumps stopped, besides all the damage to the control systems connecting to the core and their controls. In all likelyhood, many things were not being measured. BTW, magnetic recording media is VERY susceptible to radiation, and degrades quickly when exposed to it. As well as water and other debris if any information was stored in the reactor buiildings. Yeah, "pretty well under control", if you can call the rickety and rigged setup they have going that must deliver constant large volumes of water day and night, rain or shine, into pools that are in buildings which it hard to believe are even standing up! With earthquakes and typhoons. No problemo! The melted fuel has burned holes through the bottom of the containment.[/QUOTE] There are no "pathways" to cool the corium (melted out-of-control fissioning reactor core material), the pathways, they are NO MORE. All gone!
Japanese quake picked up by space satellite... Japan quake 'heard at edge of space' 10 March 2013 - The great Tohoku earthquake in Japan two years ago was so big its effects were even felt at the edge of space.
Hmmmm....so they're claiming that the reactor coolant piping ruptured during the seismic shocks.... How many Fukushima workers were parboiled from the resulting explosions of steam that would have had to have happened when 500 degree water under pressure is suddenly released from confinement? Answer: NO Fukushima workers were parboiled. Which means the pipes did not fracture in the earthquake. The primary containment system for any reactor system is the reactor vessel and piping integrity. The secondary containment is the walls of the reactor compartment. The third containment is the outer building, which is built to stronger codes because it must contain a higher overpressure. Generally, reactors containments are made of steel and concrete, and aren't usually known for their compliance....which is the engineering term for the reciprocal of stiffness. They're relatively rigid structures and a complete analysis of their normal modes and frequencies is a standard part of the approval of every building design, especially in earthquake prone regions. In other words, the article the OP cites is full of (*)(*)(*)(*).
