In the control room I think it is a meter Like up and down not a round meter.

The firm says robots on Tuesday detected radiation levels of up to 1,120 millisieverts per hour inside the No.1 reactor building. It says some contaminated water may be leaking from the reactor into external pipes.

Japan Utility President Stranded as Crisis Began

Water may be leaking from the spent fuel pool of the No. 4 reactor.

More than 1,500 spent fuel rods are stored in the pool, the largest number at the site.

Tokyo Electric Power Company, or TEPCO, has been injecting water daily into the pool to make up for the loss of cooling function and prevent the fuel rods from being exposed and further damaged.

TEPCO has poured in 140 to 210 tons of water over each of the last few days. The company found that water levels in the pool were 10 to 40 centimeters lower than expected despite the water injections.

Japan's UN Ambassador Tsuneo Nishida has asked other countries not to overreact to risks associated with the Fukushima Daiichi nuclear power plant accident.

Nishida was addressing a meeting in New York on Tuesday marking the 25th anniversary of the Chernobyl nuclear disaster, arranged by Ukraine and other countries.

Can we at least react?

Hi, guys, came on board for a while, but have to be pulled off the desk again. Cheers. Thanks.

TEPCO is in deep for sure.They have no plausible deniability.
by Ralph Unger 4/27/2011 6:05:39 AM

TEPCO says the contaminated water levels are rising.

At the No.3 reactor, the contaminated water level in a tunnel is also rising. The firm says the water was 98 centimeters from the top of the tunnel as of Tuesday morning.

TEPCO sets one meter as the limit at which it should begin removing contaminated water, but it has not yet found a location to transfer the contaminated water to.

TEPCO, says 3-week test-spraying of the agent proved that it keeps radioactive dust from being blown away.

TEPCO plans to spray 1-million cubic meters of the agent on the 500,000-square-meter compound by the end of June.

The test-spraying was done by workers using a hose, but a remote-controlled vehicle will be used for further spraying to minimize workers' radiation exposure.

The spraying is to be followed by work to cover reactor buildings with huge filter sheets to prevent further releasing of radioactive material into the environment.

The amount of data available for oxidation of Zircaloy
in air is not as substantial as that available for oxidation
in steam. Hayes and Roberson’* measured corrosion depths for
pure zirconium in moist air for a wide range of temperatures,
but their data contain considerable uncertainties in regard
to the reported temperatures, since the techniques for measur-
ing temperatures.and maintaining isothermal conditions were
not well refined at that time (1945).

I will send this document to the GOJ and they will have a slam dunk win case against TEPCO LOL.

Oops GOJ is TEPCO. NVM.

@dean great slides @Ralph I hope they have leant more since then or we are all doomed @Rob maybe that is the only place the robot can get !
by elainekirk 4/27/2011 7:13:49 AM

@Dean - what do you think of Gundersen's hypothesis about some sort of criticality explosion at #3?
by hudebnik 4/27/2011 7:55:43 AM

The flash he mentions is very odd. Not a thing caused by hydrogen.
by Ralph Unger 4/27/2011 7:58:42 AM

And it was a HUGE explosion, heard/felt 25 miles away.

And also on www.zerohedge.com a thought provoking article about the stuxnet computer virus and nuclear plants (read to end of article). I'm not sure I believe it, but...
by hudebnik 4/27/2011 8:42:03 AM

@hudebnik - I think it's quite farfetched. It certainly had nothing to do with Fukushima, but the notion that it can be reverse engineered to attack other installations is bordering on ludicrous. It's a highly targeted program which seeks only one target. It goes after centrifuges at one plant. I can't say for certain it can't be use against any other controllers using Siemens technology, but there's a level of knowledge required which can't simply be found by Googling.
by Hank Scorpio 4/27/2011 9:13:11 AM

i have a stupid question but i wonder all the time: how do they get the fuel in and out the building ? the elevator ? and how do they move it to the common pool ? on a truck ?
by Edano 4/27/2011 9:38:01 AM

nobody here ?
by Edano 4/27/2011 9:41:02 AM

@Edano - Great question I don't know the answer to. I do know the water acts to shield almost all of the radiation in the transfer from the reactor to the pool. As to getting it out, I would assume they put it in a cask before taking it out of the water. I know they have trucks designed to move dry casks around.
by Hank Scorpio 4/27/2011 9:54:11 AM

@Hank Scorpio : and inside the building ? they store them in casks on the upper floor ? and then ? i don't see any huge door. maybe an elevator ? on the refuelling crane, they are vertical. but they need them horzontal in a cask. how is this done ?
by Edano 4/27/2011 10:13:49 AM

they are 4 meters long.

Water may be leaking from No. 4 reactor fuel pool

The operator of the troubled Fukushima Daiichi nuclear power plant says water may be leaking from the spent fuel pool of the No. 4 reactor.

More than 1,500 spent fuel rods are stored in the pool, the largest number at the site.

Tokyo Electric Power Company, or TEPCO, has been injecting water daily into the pool to make up for the loss of cooling function and prevent the fuel rods from being exposed and further damaged.

TEPCO has poured in 140 to 210 tons of water over each of the last few days. The company found that water levels in the pool were 10 to 40 centimeters lower than expected despite the water injections.

The walls of the reactor building supporting the pool were severely damaged by a hydrogen explosion last month. TEPCO says the pool may have been damaged by the blast as well.

According to a schedule announced earlier on containing the ongoing emergency, TEPCO plans to install concrete pillars to support the fuel pool by around July to increase its earthquake resistance.

TEPCO revises nuclear fuel damage ratios

The operator of the troubled Fukushima Daiichi nuclear plant in northeastern Japan has reassessed its estimates of fuel damage in reactors No.1 to No.3.

Tokyo Electric Power Company on Wednesday announced new estimates of damage after the country's nuclear safety agency questioned the accuracy of the initial assessments. The utility has revised the estimated fuel damage in the No.1 reactor from 70 percent to 55 percent, saying radiation levels were not correct.

TEPCO also says that it acted inappropriately in excluding fuel damage of less than 5 percent in calculating total damage ratios for the No.2 and No.3 reactors.

As a result, the utility revised upward its estimates of damaged fuel in the No.2 and No.3 reactors by 5 percentage points each to 35 percent and 30 percent respectively.

The company released its initial estimates as of March 15th, based on radiation levels in the reactors and their containment vessels.

Earlier this month, the Nuclear and Industrial Safety Agency raised the crisis level at the Fukushima plant to the highest 7 on the international scale, based on its estimate of the volume of released radioactive substances.

TEPCO says the corrected estimates will not affect the agency's crisis rating.

@Edano Mornin'! I think Nancy knows the answer to your question. She was talking about it one day. I think inside the plant they use a flume type system. How they get the stuff to the common pool I don't know. I was wondering that myself the other day. I do know it has to be kept in water or it overheats if it's fresh. Might be a good question for Dean as well.

i wonder if they put the entire cask in the spent fuel pool and open it inside. morning fitter
by Edano 4/27/2011 10:48:21 AM

@Edano i have seen a report that shows 1) damage to seals (over 10 years) ffrom the moisture of being in the pools... 2) they have a drawing that shows a caskest area underwater ????? but i really son't know!!!
by fitter 4/27/2011 10:50:47 AM

putting the cask into the water seems to be dangerous, since the water is irradiated and you sure don't want to have radiation on the outer side of the cask. ....... clomoplicated thing it seems.
