Something really strange about Fukushima compared to Chernobyl
In Chernobyl they dropped 5,000 tons of sand, lead and boric acid then they HURRIED to cover the molten reactor in order to prevent RAIN from entering:

At the time there was still fear that the reactor could re-enter a self-sustaining nuclear chain-reaction and explode again, and a new containment structure was planned to prevent rain entering and triggering such an explosion, and to prevent further release of radioactive material.

[link to en.wikipedia.org]

You can hear the same said here, starting at minute 6:10:

[link to youtu.be]

So... they didn't pour hundreds of thousands of tons of water on the molten reactor, they actually tried to prevent water from getting to it!

In Fukushima not only did they leave most of the reactor buildings exposed to the elements (including rain) for a year or more, but we are told they were/are actually pumping water in the reactors that suffered meltdowns.

So why was water considered a risk, a facilitator of a chain reaction, in Chernobyl, while in Fukushima it is used in massive amounts?

UPDATE FOR MORE INFO:

The fuel rods in reactor 1 have melted but we are told TEPCO is continuing to pour water into reactor 1:

A massive amount of highly radioactive water is accumulating inside the plant's reactor buildings and adjacent reactor turbine buildings as a result of the continuing injection of water to cool the Nos. 1 to 3 reactors, which have suffered meltdowns due to last year's nuclear accident.

[link to mainichi.jp]

Thus TEPCO is pouring water over a blob of melted nuclear fuel. Is that the correct thing to do?

In Chernobyl they even drained a water reservoir from under the reactor in order not to allow the melted fuel blob to get into contact with water (!!!):

Velikhov said the damaged reactor, pressed down from above by thousands of tons of sand, lead and other fire-extinguishing materials, was in danger of plunging into an underwater reservoir, which would have released radioactive steam into the atmosphere.

Re: Something really strange about Fukushima compared to Chernobyl
yeah.. you can look at it in one of two ways...

not pouring water on chernobyl back then.. probably either A: made it worse.. or B: helped tons..

so maybe the dumbasses thought if they tried something different it would help.. i mean its simple.. they prob were like "hey! instead of drying this baby out like they did in chernobyl... how about we try and drown this sucker!" u know?

 Quoting: Cellz


They say it helped tons because 50% of the molten nuclear fuel mixed with the sand and turned into "lava" that eventually cooled several levels below the reactor vessel, becoming trapped in this shape and lowering the chances of a chain reaction (starting at minute 4:40):

Yeah. They may also have problems getting the sand, boric acid and other stuff where it needs to be. And then they also probably thought... "hey, we have a big body of water to our east, in easy reach, why not use it".

The question I have, and I hope someone that knows this stuff could help us, is why was water considered a facilitator of a chain reaction in Chernobyl, while in Fukushima it is used in massive amounts???

fukushima used MOX, chernobyl was not using this material.

it's related to this maybe someone can explain it better because in english it's a bit difficult for me 1dunno1

the only thing i'm sure is MOX is far more toxic than what chernobyl was using (toxic dust full of particles).

Yes, but does that make a big change in how to handle molten reactor fuel?

The Japanese used lots of water and left the buildings exposed to the elements. In Chernobyl they considered water a hazard and hurried to prevent rain from getting into the reactor.

The discrepancy seems too big. How can it be explained?

MOX is used only in the Core of Nr. 3
but not in Nr.1, 2., 4.!

You should wait for a Explanation from the Guys
who believe in a Hydro-Cesium Volcanic Reaction/ Explosion,
they may are able to explain this banana2
(i do not believe in this)

One of the biggest Differences is that the Fuel in Chernobyl
was under the open Sky, F'Shima is not, it's still
inside of the Containment!

Re: Something really strange about Fukushima compared to Chernobyl
I'm not a scientist, and I certainly do not have any training in 'how to dispose of radioactive waste safely' but the more I read about this, the more dismal the situation becomes.

I had read an interesting article recently....(link below) that talks about some of the scientific studies that have been done. Lots of good information at that link if you've got time to read it all. But the article stated that only 20% of the radiation has stayed in Japan, while 78% has gone into the pacific ocean. The other 2% went airbourne and eventually landed on the west coast of the US and Canada. These levels are spreading out to the entire world, and the levels will continue to increase and yet no one seems to know what the hell to do about it....(???)

The article goes on to tell of Japan's decision at the end of last year to start burning all of this radioactive debris, then mixing non-radioactive debris to dilute it...(huh???) then spread it around like some type of compost or something. AND....this is their solution for the next several years....burn, mix, spread, burn, mix, spread....repeat for 3 years.

Am I missing something here?? Does this sound reasonable to ANYONE? What would be some logical solutions at this point? Anyone know? Cuz everything I've been reading doesn't give much hope. The time to react with limited damage to the environment has long since passed, and now I'm not sure anything really CAN be done

I just LOVE morning doom, don't you? rant

@ladyannie,
this is a different Topic and you should open a Thread for it,
but let me say that there is no other way,
in the last year we had 38 Fires because of Self Combustion inside of this really huge Mountains,
imo. it is much more safe to burn this Stuff in a controlled
Manner than let it burn for years in our normal Environmemt,
without any kind of Filtering!

yes MOX is the big problem and the difference.

they are avoiding it, only talking about radiations and stuff like this in purpose for a reason.

Maybe Chernobyl didn't have giant pools of used rods stacked on top in pools that needed to be cooled down?

 Quoting: Vlad Tepes


It was a different type of reactor.

Graphite moderated with most of the graphite in place.

So the fuel had a tendency to be more active (close to fission) without even adding water.

Fukushima reactors are water moderated.

If that water was supposed to get where it was needed then the top of those containment vessels was considered breached.

Re: Something really strange about Fukushima compared to Chernobyl

If these facts are correct :

"...the amount of nuclear material in the spent fuel pools at Fukushima is greater than all of the nuclear fuel at Chernoybl:
Science Insider noted yesterday:
The Daiichi complex in Fukushima, Japan … had a total of 1760 metric tons of fresh and used nuclear fuel on site last year, according to a presentation by its owners, the Tokyo Electric Power Company (Tepco).
The most damaged Daiichi reactor, number 3, contains about 90 tons of fuel, and the storage pool above reactor 4, which the Nuclear Regulatory Commission’s (NRC’s) Gregory Jaczko reported yesterday had lost its cooling water, contains 135 tons of spent fuel.
The amount of fuel lost in the core melt at Three Mile Island in 1979 was about 30 tons...
Chernobyl reactors had about 180 tons when the accident occurred in 1986.
That means that Fukushima has nearly 10 times more nuclear fuel than Chernobyl.
It also means that a single spent fuel pool – at reactor 4, which has lost all of its water and thus faces a release of its radioactive material - has 75% as much nuclear fuel as at all of Chernobyl.

However, the real numbers are even worse.

Specifically, Tepco very recently transferred many more radioactive spent fuel rods into the storage pools. According to Associated Press, there were – at the time of the earthquake and tsunami – 3,400 tons of fuel in seven spent fuel pools plus 877 tons of active fuel in the cores of the reactors.

That totals 4,277 tons of nuclear fuel at Fukushima.

Which means that there is almost 24 times more nuclear fuel at Fukushima than Chernobyl"

Re: Something really strange about Fukushima compared to Chernobyl
099 in UK Regular detectors can't pick up a lot of the particle radiation because it travels only one or two millimeters. If the particles lodge in your lungs or are ingested with food or water they are inside you blasting away from point blank range causing cancers etc. See some of Gundersens early videos. Heavy particles from Fukushima were found in New England within weeks after the intial explosions. The steam from the water would cause the particles riding on concrete dust water molecules (like a baloon can carry weights) to be carried long distances. SEE JAPAN BALOON BOMBS IN WW II. Do a search on it.
