Removing highly toxic water remains difficult task at nuke plant

TOKYO, April 14, Kyodo

The government's nuclear safety agency on Thursday continued to grapple with pools of highly radioactive water at the crisis-hit Fukushima Daiichi nuclear power plant, as the level of polluted water filling an underground trench edged up again after it finished pumping out around 660 tons of water.

The removal of around 60,000 tons of contaminated water from the basements of the Nos. 1 to 3 reactor turbine buildings as well as trenches connected to them is vital because the water is hampering work to restore the cooling functions of the reactors lost since the March 11 earthquake and ensuing tsunami.

The pools of contaminated water are believed to be a side effect of plant operator Tokyo Electric Power Co.'s emergency efforts to continue injecting water into the reactors and their spent nuclear fuel pools from outside to cool them down.

The operator known as TEPCO pumped out around 660 tons of highly radioactive water Tuesday and Wednesday from one of the trenches to a ''condenser'' inside the nearby No. 2 reactor turbine building, where during normal operation steam from the reactor is converted into water.

But the Nuclear and Industrial Safety Agency said that the water level in the vertical part of the trench as of 11 a.m. Thursday had increased by about 4.5 centimeters from the level observed at 6 p.m. Wednesday.

The level of the water is now only 1.5 centimeters lower than shortly before the water-transfer mission started at 7:35 p.m. Tuesday.

Hidehiko Nishiyama, the agency's spokesman, told a morning press conference that the rise in the water level is likely linked to the continued injection of water into the No. 2 reactor core, which is necessary to prevent the nuclear fuel inside from overheating.

''As there is believed to be around 20,000 tons of water (in the No. 2 reactor turbine building and the trench connected to it), we're feeling the difficulty of lowering the level of the water in a stable manner,'' he said.

TEPCO is preparing to transfer more of the highly radioactive water into a facility for nuclear waste disposal at the plant, which can accommodate 30,000 tons of liquid.

Work is under way to ensure that the facility will be able to contain highly radioactive water safely without fear of the stored liquid leaking outside, but Nishiyama told the press conference that he was not sure when it will end.

The water in and around the No. 2 reactor turbine building is believed to contain higher concentrations of radioactive substances than other contaminated water found at the site, and is believed to originate from the No. 2 reactor's core, where fuel rods have partially melted.

The agency decided to remove water from the trench first as it feared that the water inside the trench would overflow and leak into the Pacific Ocean.

TEPCO also started looking into how to check the quake resistance of already heavily damaged reactor buildings at the site in line with an order issued Wednesday by the nuclear regulatory agency, in light of strong aftershocks from the March 11 quake.

The agency has told the utility to immediately examine the buildings and consider reinforcement work if they are judged as not sufficiently quakeproof.

TEPCO, however, has said that it cannot ''immediately conduct an investigation'' unless it confirms the safety of areas where checks will be conducted.

To enhance preparation for tsunami waves triggered by aftershocks and other emergency situations, emergency diesel power generators and vehicle-mounted power sources are to be placed at higher ground, while backup units for water injection at the troubled Nos. 1 to 3 reactors are expected to be installed, according to the nuclear agency.

Meanwhile, concern grew over the state of the No. 3 reactor at one point, as the agency said in the afternoon that the temperature of part of its reactor pressure vessel was found to be rising suddenly.

But TEPCO officials said that the data were likely due to a glitch in a measuring instrument, because other temperature data related to the vessel has not shown a similar rise.

"To prevent further contamination of the sea from radiation leaks, TEPCO will install iron sheets as well as ''silt fence'' barriers close to the No. 2 reactor water intake and other areas near the plant. The utility will also place 100 tons of sandbags at a breakwater, according to the agency."

There was an earlier reference to the breakwater shoring (prob 29th), but I do not have access to it.

As I remember, after reactor building 4 exploded they first cooled down the reactor 4 spend fuel pool with sea water. Now they are topping it up with sweet water. Sea water and fresh water don't mix very well and the fresh water, being lighter, floats on top. My guess is that the highly contaminated salt water was not sampled, only the relatively uncontaminated sweet water upper layer.

In other words, the 400 cc sample may not be a representative water sample. Therefore statements about the intactness of the rods are shakey.

Mendel.



Assuming much of the radiation is coming from the fission of fuel rods that melted when the water level dropped I would guess the water at the top of the reactor to be more radiated then that at the bottom.


More radiated perhaps, but not more concentrated in radioisotopes (which is what they measured).


Do radioisotopes fall to the bottom of the reactor?


No, they remain in the solvent, in this case sea water, which remains at the bottom part of the pool. The fresh water in which the radioisotopes have not been dissolved remains floating on top.

U.S. sends water storage tanks, trailer to Fukushima nuclear plant

TOKYO, April 14, Kyodo

The U.S. Department of Energy is shipping five large stainless steel tanks for storing water contaminated with radioactive materials and a tractor trailer with a shielded tank to the crippled Fukushima Daiichi nuclear power plant as part of its assistance, the U.S. Embassy in Tokyo said Thursday.
Details regarding the size of the tanks and expected arrival date were not immediately known.

Many thanks to you, Mike, for this insightful and illuminating analysis of these historic events. I would read through several pages of posts if they included such pertinent and revealing information, so I feel you have no need to apologize for the length of your post.

I have to get ready for work, and am unsure as to how much attention I will be able to pay to this thread while there. Please keep up the great work everyone, even those who are causing the internal (to this thread) questioning as this will only serve to further distill the knowledge presented here into a much more concise and meaningful form.

Still no Redneck, hmmm...

Radiation surges above 4's fuel pool search.japantimes.co.jp...

By KANAKO TAKAHARA
STAFF WRITER

Radiation has risen to high levels above the spent-fuel pool at reactor No. 4 and its temperature is rising, the nuclear safety agency said Wednesday, indicating the fuel rods have been further damaged and are emitting radioactive substances.

The radiation level 6 meters above the spent-fuel storage pool at the crippled Fukushima No. 1 nuclear plant was measured at 84 millisieverts per hour Tuesday. Normally, it's 0.1 microsievert.



The temperature of the pool was 90 degrees, compared with 84 before it caught fire on March 15 in a suspected hydrogen explosion, the agency said.

"It's quite an amount," figured Hidehiko Nishiyama, a spokesman for the Nuclear and Industrial Safety Agency.

Tokyo Electric Power Co. was unsure whether the surge in radiation was being caused by the spent fuel rods or radioactive material leaking from the reactor's pressure vessel.



"The temperature was rising and we don't know the water level of the pool, so we thought it would be safer to pour water," said NISA's Nishiyama said.

Tepco said it is planning to move the spent fuel rods out of the storage pools at reactors 1 through 4 so they can be moved to a safer location, although details on when and how haven't been decided yet.

Some of the options Tepco is considering include pulling the rods out with a crane or building a special structure nearby to pull them out.

But these tasks will be tough because the site is so radioactive and cluttered with debris from last month's hydrogen explosions. Meanwhile, the water level of radiation-contaminated water in the tunnel-like trench at Unit 2 dropped by 4.3 cm Wednesday morning after Tepco started pumping lethally radioactive water from its flooded turbine room into a nearby storage facility the day before.

From a Korean newspaper (Chosunilbo):

No New Measures Needed to Counter Radiation Health Risks in Japan




The World Health Organization says no new public health measures are needed to counter the higher levels of radiation being emitted from Japan's Fukushima Daiichi nuclear power plant. On Tuesday, Japanese authorities raised their rating of the severity of the accident at the nuclear plant to seven. WHO says the severity of the releases of radioactive material at the Fukushima plant is a cause for concern. But, in terms of public health, it says the countermeasures taken soon after the accident in mid-March, are still good.


Emphasis added mine, what "countermeasures" were taken soon after the accident to ensure public health?


"Those that are in place, things related to the evacuation zone, the relocation of certain populations, the measures associated with the early intake of potassium iodine pills for the population that has been identified by the Japanese government as appropriate, the issues related to food safety and controls -- things like that…Those public health recommendations are still valid," she said.


Haven't they been told they need to relocate themselves?


On a related issue, Neira, says WHO does not see any need to impose a ban on the export and consumption of food from Japan. She says no food is being grown in the contaminated areas. And, she notes, Japanese authorities test food before it is exported to make sure it is safe.


Didn't they show someone on Japanese TV eating food from these areas?

I feel this subtle shift in language to speaking of "refugees" is quite telling. I'd have to read back and see if reports of the Emperor's visits tended to use the word "evacuees" or "refugees" but I recall the former rather than the latter. Even so, as "refugees" has been used in a report concerning a very important member of the Imperial House, it can be taken as reflecting something of the Imperial perspective on this continuing disaster -- especially in relation to nuclear refugees and all that implies.

Apologies for the long post. Thanks to anyone who has had the patience to read through it!

JustMike,
Many thanks for giving us here at ATS a between the lines report on the artful way the Japanese Royal family has given certain messages to their people, very insightful indeed. A few of Japans cabinet ministers could learn a lot by following ther idealism.

10 Bar = 145.038 PSI.

Given the massive size of these vessels, that is a hell of a lot of pressure. Especially if it is water pressure.




Found this graph on the same site, and another one listed below first one. Maybe you can make heads or tails of them.



And numbers chart.



Des

Well, this spreadsheet is for internal consumption of the Nuclear and Industrial Safety Agency & Ministry of Economy, Trade & Industry, it's on a secure server that they didn't password protect the files. I don't know how long this link will be available!

A rough transliteration of the spread sheet column headings: a=date, b=atomic furnace level A (mm), c=nuclear reactor water level B (mm), d=atomic furnace pressure force A(Mpa g), e=atomic furnace pressure force B (Mpa g), f=pressure vessel water temp (ºC), g=lower pressure vessel temp (ºC), h=DW (Mpa abs), i=SC (Mpa abs), j=DW CAMS (Sv/h), k=SC CAMS (Sv/h)

On the bottom of the spreadsheet are selection boxes, starting from the left, clicking the first box gives you the spreadsheet for the reactor selected from 3/15, the second box gives you a chart of pressure force A&B, the third box is a chart of pressure vessel water temp upper & lower, the forth box will give you a spreadsheet of readings from ~3/15. The left right arrows on the bottom will scroll the bottom boxes to the next reactor, using the same sequence for the display. Reactors 1,2,3,5,6 are on this spread sheet. 4 is not there!
Have fun!
Oh, and thank Masato-san for posting all this info, his twitter address is on the spreadsheet!

An addendum: There is a pressure correction factor to be applied to pressure readings as follows:
"Reactor pressure until midnight on April 6, the correct list of each number based on TEPCO announced April 06, 1.111 after correction with the value multiplied by the number."
That's a transliteration of the notice in red on the spreadsheet.


Some definitions to column headers:
On columns B&C the level of the water in relation to the rods, a negative reading means the rods are uncovered by the given dimension.

I've already cited where Tepco was planning to put sandbags at a breakwater, there is a barge with a crane between the inner and outer breakwaters, what is outrageous assuming that this is what it is doing there? It may not ultimately be correct but is a simpler answer, right now, than a conspiracy theory.

yes there is a barge with a crane right where you said it is..and you are probably right..it is unloading sand bags...however that has nothing to do with the "water barges" that have been talked about...

Perhaps it would be best if we continue this in U2U so feel free to send me any proof that you have that those objects under the white sheets are sandbags like you claim

Russia nuclear chief says Japan exaggerates crisis

Sanya, China (AFP) April 13, 2011 - The disaster at the Fukushima atomic power plant cannot be compared to Chernobyl, Russia's nuclear chief said on Wednesday, suggesting Tokyo was exaggerating the emergency, possibly for financial reasons.

"It is hard for me to assess why the Japanese colleagues have taken this decision," Sergei Kiriyenko, the head of Russia's state nuclear agency Rosatom, told reporters in the southern Chinese city of Sanya on the eve of the BRICS summit.

"I suspect this is more of a financial issue than a nuclear one."

Earlier this week Japan upgraded its month-old nuclear emergency to a maximum seven on an international scale of atomic crises, placing it on a par with the Chernobyl disaster in 1986.

Kiriyenko appeared to suggest that the Japanese authorities were seeking to reduce the burden on insurance companies.

Found this part of the article quite interesting, wonder why the Russian nuclear chief would say something like this. Especially with the information coming out now.

Oh well, interesting none the less....
