Japanese nuclear plant may only have a few hours....

Let me Google that for you

I don't mean to be rude. I just think the, "let me" thing is funny. I think it will only work for a little while on this topic. Now it does come up with a couple of stories.


Don't patronize me. I'm on dial-up...it's slow.

I stole this from ZH...interview from irate Japanese reporter.

Obviously a lot has happened over the past couple of weeks, but what are the main things you've learned?


Basically, something that I knew from the beginning, but has become more blatant yesterday and today [March 27-28], is this terrible situation where the government and TEPCO are suppressing information. To be more specific, I thought it was strange that there was nothing written about plutonium when the data about reactor 3 was given out at the TEPCO press conference on the 27th, so I asked them if it was true that no plutonium had been detected in reactor 3, and for how long it had not been detected. TEPCO answered: 'Plutonium hasn’t been detected.' To confirm what they were saying I asked if perhaps it wasn't that none had been detected, but that they hadn't actually taken any measurements. They were alarmed, and it turned out that it wasn't even that they hadn't taken any measurements, but that they didn't have the instruments to do so in the first place.


That's one example. Another is the question of where exactly has the TEPCO company president gone? There was a rumour doing the rounds a while ago that he had been hospitalised, when actually he had been away because of fatigue. This time they're using the pretence of hospitalisation for the same situation. All of it's lies. It's emblematic, isn’t it? [Note: TEPCO president Masataka Shimizu was hospitalised on March 29, and subsequently resigned.]

Japan's attempt to plug leaking reactor fails

Japanese officials grappling to end the nuclear crisis at the earthquake and tsunami-crippled Fukushima plant are focusing on a crack in a concrete pit that is leaking highly radioactive water into the ocean from a crippled reactor.

Power plant workers attempted to fill the shaft with fresh concrete on Saturday, but that did not change the amount of water coming out of the crack, spokesmen for Tokyo Electric Co (TEPCO) told a news conference.

They will try to block the leak on leak again on Sunday by injecting polymeric material into the trench and use additional concrete to prevent contaminated water from leaking into the sea.

A Tokyo Electric expert will visit the site on Sunday and decide what polymer to use before the work begins.
The water has been leaking into the sea from a 20-centimetre crack detected at a pit in the reactor where power cables are stored, the government's nuclear safety agency said.

TEPCO said the pit is connected to the No. 2 reactor's turbine building and a tunnel-like underground trench, in which highly radioactive water has been spotted so far.

Hidehiko Nishiyama, deputy head of the Nuclear and Industrial Safety Agency (NISA), said on Saturday that to cool the damaged reactor, NISA was looking at alternatives to pumping in water, including an improvised air conditioning system, spraying the reactor fuel rods with vapourised water or using the plant's cleaning system.

Operators of the plant are no closer to regaining control of damaged reactors, as fuel rods remain overheated and high levels of radiation are flowing into the sea.

Bodies of 2 Missing Workers Found at Japanese Nuclear Plant

TOKYO — The operator of the stricken Fukushima Daiichi Nuclear Power Station said Sunday that two workers at the plant who had been missing for several days had been confirmed dead.

The operator, Tokyo Electric Power Company, said the workers were found in the basement of the turbine building connected to the plant’s No. 4 reactor. The company did not say how the workers died. But various news media reports say the men lost blood and went into shock.

...

the strategy to cool the plant’s reactors and spent fuel storage pools by pumping hundreds of tons of water a day into them...The Japanese authorities have said they have little choice at the moment, since the normal cooling systems at the plant are inoperable and more radioactive material would be released if the reactors were allowed to melt down fully or if the rods caught fire.

...

the leak discovered Saturday raised fears that contaminated water might be seeping out through many more undiscovered sources. He said that unless workers could quickly stop the leaking, Tokyo Electric could be forced to re-evaluate the so-called feed-and-bleed strategy, in which they flood the reactors and fuel ponds with water and then release the steam that the hot fuel rods generate.

“It is crucial to keep cooling the fuel rods, but on the other hand, these leaks are dangerous,” Mr. Iguchi said. “They can’t let the plant keep leaking high amounts of radiation for much longer,”

I've seen a couple of reports that the crack in Reactor 2 spilling into the sea is 20cm. I am hoping that is height. Does anyone know of other dimensions? Width? If the crack is 20cm wide then it is going to be hard to stem.

I was reading a report earlier that said 8" wide, but another yesterday that said 8" long.

Engineers try to stem a leak of highly radioactive water spilling into the Pacific with a new method after concrete failed to seal a crack discovered Saturday. They injected polymer that can absorb enormous amounts of water into a pipe that connects to the maintenance pit from where the water is leaking. It's not yet known if that has worked.

Anyone know stores which may have Potassium Iodide? I've tried CVS, Walgreens, Vitamin World, Vitamin Shoppe (only had crazy expensive liquid which would take like $60 a person), whole foods market were the only people whom said they carry it but are out of stock.

I live in Miami and we dont have Rite Aid >.>

This place should be back in stock Aprin 4th:

they injected a mix of sawdust, shredded newspaper and a polymer that can expand to 50 times its normal size when combined with water. The polymer mix had not yet stopped the leak Sunday night but engineers have not given up hope and should know by Monday morning whether it will work.

The polymeric powder is water absorbent that can soak up 50- times its own volume, the agency said. It is the same absorbent used in babies' diapers.

BINGO! - found you! - maybe...

Baby Diaper Polymer

Description

Modern baby diapers contain polyacrylic acid, a super-absorbent polymer. When some of this polymer was added to a beaker with water and stirred, it absorbed many times its weight in water.

Explanation

Polyacrylic acid is a polymer made from the monomer acrylic acid. These long chains contain thousands of monomer units, and the polymer also has some cross-linking between the chains. Many polymers, such as polyethylene and polystyrene (used in trash bags, plastic bottles, and Styrofoam®, for example) are hydrophobic, meaning they repel water. Polyacrylic acid, however, is very hydrophilic - it attracts water. That's because of the carboxylic acid groups (COOH) in the polymer, which can hydrogen-bond to water molecules.

Diapers contain a small amount (4-5 grams) of polyacrylic acid in a powder form, which is mixed into the fluff in the middle layer of the diaper. The inside layer of the diaper allows water to pass through it into the absorbent middle layer, and the outer layer is waterproof, so both baby and mommy stay dry. Polyacrylic acid can absorb about 30 times its weight in water, or about 30 mL (1 oz) of water per gram, so a typical diaper can absorb 120-150 mL of water (about a half cup). That's about how much a baby... um... pees.

ummm... maybe, because the articles say can absorb 50 times, while this says 30 times. Is this the right polymer?

Looking at this picture I see a large horizon to the workers right, and a tower behind the worker to the left. The large horizon tells me this crack is close to the sea, and lookign at the satellite photo below...


The only structures that look at all similar to the structure immediately behind the worker is located on the seawall (above the "breakwaters" label) which seems a stretch to describe as "close to reactor 2"
 
Hmm I'm glad I was in the era that put cotton nappies oops diapers on my baby. All that chemistry makes my head spin. Something quaint about a product that can stay the most lethal substance known to man that can also spend years close to precious wee newborn babies bottoms. Must be good!

So what about strontium 90? Is anyone measuring that? There was that article from the irate Japanese journo who when he had asked about the presence of plutonium had been told by Tepco reps that no plutonium had been detected. Then he found out they did not have anything to actually measure the stuff. So have they got apparatus to measure Strontiom 90 I wonder?

It is criminal that these people were not better prepared for a catastrophe. (I know it has been said before!)
