Something Odd Is Happening at Reactor Number 4

George Washington's picture




 

NHK reports:

The
operator of the troubled Fukushima Daiichi nuclear power plant is
carefully monitoring the situation at the Number 4 spent fuel pool,
where the water temperature is rising despite increased injections of
cooling water.

Tokyo Electric Power Company, or TEPCO, says it
will inject 210 tons of water into the pool on Monday, after finding on
Sunday evening that the temperature in the pool had risen to 81
degrees Celsius.

***

On Friday, TEPCO found that the
pool's temperature had reached 91 degrees, so it began injecting 2 to 3
times the amount of water.

***

The Number 4 spent fuel pool stores 1,535 fuel rods, the most at the nuclear complex.

(Bear in mind that the amount of radioactive fuel at Fukushima dwarfs Chernobyl.)

As I noted on April 2nd:

Nuclear engineer Arnie Gundersen notes that the spent fuel rods in reactor number 4 have no water, and the rods are exposed:

In addition, the official Japanese atomic energy website shows 4,250 sieverts/hour of radiation inside the containment vessel at reactor 4 ("S/C" stands for suppression chamber):

These are very high levels of radiation. As I noted on April 10:

Radiation levels were apparently about 300 sieverts per hour ... right after Chernobyl exploded.

To
be clear, the Chernobyl figure is radiation released into the
environment, while the reactor 4 figure is radiation within the
containment vessel. I have seen no evidence to date that reactor 4 is
leaking.

This is especially odd given that reactor 4 was supposedly shut down prior to the earthquake
for maintenance. In other words, reactor 4 was - according to
official reports - shut down, and shouldn't have very much radiation at
all. Something doesn't add up.

In contrast, the radiation inside the cores of the other reactors are much lower:

  • Reactor 1: 0
  • Reactor 5: 0
  • Reactor 6: 0

Indeed, the Japanese nuclear agency prominently displays the radiation data for all of the reactors except number 4 on it's main page. Number 4 is conspicuously absent, and you have to type in the url for the correct web page to find it.

The building housing reactor 4 doesn't seem to be quite as badly damaged as those housing other reactors:

However, a Fukushima engineer says he helped cover up a cracked containment vessel at reactor number 4 for decades.

On
the other hand, the fact that no radiation is being reported in the
drywell of reactor 4 (noted by "D/W" in the nuclear agency's tables) -
while there it is for several of the other reactors - might imply that
the containment vessel has maintained its stability.

At
this point, I don't have enough information to determine why the
radiation levels inside reactor 4 are so high compared to the other
reactors, let alone what it means. It might mean that reactor 4 is in
trouble. On the other hand, it could mean that reactor number 4 is the
only reactor which still has core integrity. In other words, maybe the
other reactor cores have much lower radioactive levels because most of
the radiation has already leaked out.

Japanese Government and Executives, NEVER ADMIT ANY MISTAKE.

DENY DENY DENY

the end.

Shampoo.

Then again how is this different that USA's Actions by these same sort of individuals?

Well one... the USA's don't do the honorable thing and don't kill themselves. 

Which is a bummer.

That's right. I also thought the japanese were different, instead I find out that all these TEPCO and government officials want is to "get their life back".

What SPF do you need for 4250 sieverts/hour ?

You´ll need Number 1 Special Prefecture Formula.  It should be available as soon as the special sauce (made from all the irradiated fish left over from Tokyo´s fish markets) has time to ferment in special containment jars mixed with fresh sea water.

Atomic Number 82 with an Atomic Weight of 207.2 should do. However you will feel a little weighed down by it.

GW,

Why didn't you post the actual URL

http://atmc.jp/plant/rad/?n=4

And provide a screenshot of it, for the sake of history?

And thanks for the hat-tip.

Not.

Yes exactly, and you're welcome for my call as well, George.  Does anyone compliment this Jerk except the Herndon Trolls?  Our tax money at work.

GW I value your posts. I was just reading you Sr90 Uranium entry also.

When this all first started you provided a very helpful list of herbs, vitamins, etc that one might take to avoid cesium and I-131 uptake in body. Is there ANYTHING one can take to stop absorption of plutonium or Uranium as one can do with the I-131?

analysis of the hi-res photos which proves the reactor core in building 3, which housed the Plutonium MOX fuel, blew up.

Do all vegetables take up the plutonium/uranium, cesium as they grow?
Some veggies are helpful as you've noted be a shame if they became contaminated in their cells as opposed to outer leaves etc.

Laddie,

Apparently iron inhibits the absorption of plutonium, found about 2/3 the way through this link, it also has some other helpful suggestions:

Thanks HK that is helpful to know, though they say men shouldn't take iron, I suppose the alternative is worse.

Thanks also tamboo

Why were the posts "junked" for what possible reason? Perhaps ZH should do away with the junk marker as then information is CENSORED by those who do not wish such information discussed where others might see it.

ZH could institute a ratings system as long as the voice, the information is not thereupon hidden or deleted.

TRUTH is TRUTH and we know the government LIES, lies all the time, and that the government does NOT care about the real American people, except they want our $$$ until they can finish the job.

Do rent the film ON THE BEACH stars Gregory Peck.


Be wary of he who would deny you access to information, for in his  heart he dreams himself your master.

I remember seeing on the beach on AMC a few years ago, and I'm surprised that they allowed that to be shot back then.  What is happening is that we have uncontrolled fission happening in reactor 4, in the spent pools.  The pools have a 1700 tons of spent fuel and the rods from the reactor that still had time to burn.

Also, they have been finding Uranium-234 and 238 in the air since March, a month ago:

I've mentioned twice before a strange anomaly in the "explosion" of reactor #3, but nobody seems to have noticed, so I thought I'd post it one last time.

how did the roof of #3 reactor containment building begin to drop before the flash of the explosion? See my previous comment to Stunning Video of Reactor 3 Explosion:

at 1.27 the roof begins to colapse

at 1.33 is the first fireball

hows that happen?

 

If you look at the video in slow motion, it looks to me like the roof is collapsing. Is that typical of an explosion, to have the roof collapse first?

 

Can anybody explain this?

It is absolutely just like the suck a hard boiled egg into the glass milk bottle trick: when you throw the burning matches into the bottle, they consume the oxygen and cause a negative air pressure inside the bottle, letting the outside atmosphere smoosh the egg down into the bottle. Seriously.

Yes, you're right ... The fact that there are 13 times higher levels of radiation than Chernobyl from a reactor supposedly shut down BEFORE the earthquake is all SOP.

Reactor 4 was not only shut down months before the earthquake/tsunami, but all the fuel was supposedly taken out of the reactor and loaded into the spent fuel pool. This is why the pool is of great concern. Because it has relatively fresh fuel loaded in a pool that at one point held no water.

So where is the radiation inside the number 4 reactor coming from when there is no fuel in the reactor? Numbers 5 and 6 were also offloaded....which explains the zero readings.

Simon says something stinks in the nuclear wood pile.

Its likely that the "spent fuel pool" contains "spent fuel rods", not new rods. At least that how it appears in your text. Did you mean "fresh Spent Fuel rods" instead of "fresh fuel [rods]"?

The spent fuel rods are much more radioative than new fuel rods, this is because fission splits Uranium (with a very long half-life) into isotopes with very short half-lives, emitting abundant amounts of radation. Fresh spent fuel rods are the worse, since they give off lots of radiation for years. It takes several years before spent fuel rods cool down enough to the point they can be stored in dry-caskets and transported to spent fuel reprocessing plants.

I most certainly can be wrong. But my understanding is that because number 4 was in a planned shutdown the spent fuel rod pool was holding the reactors entire load of fuel rods (because the reactor was off loaded for maintenance) as well as the 'normal' high level of spent fuel rods.

The spent fuel rod pools for reactors 1 thru 4 had already been re-racked for a tighter more dense fit of spent fuel rods three times over the last 25 years and was holding well above it's originally designed load of rods, spent or otherwise.

In other words the number 4 pool was holding an abnormally high amount of spent and partially spent fuel rods when this disaster hit. This is one of the reasons why they are so concerned about the pool in number 4. Because it is the most densely packed of the 4 pools. Reactors 5 and 6 are newer and aren't carrying the same load and obviously didn't have explosions.....that we know of. Numbers 1 thru 3 pools weren't overloaded with the reactor load itself.
