@all, what was the reference to#3 having radiation leaks ??
by wtm 5/12/2011 10:11:00 AM

@wtm that rrings bells with me I will try to find it, was it in the iaea update a couple of days ago?

Nuclear fuel at Fukushima No. 1 unit melted after full exposure

TOKYO, May 12, Kyodo

Water inside the troubled No. 1 reactor of the Fukushima Daiichi nuclear power plant was at an unexpectedly low level, not enough to cover the nuclear fuel, hinting that a large part of the fuel melted after being fully exposed, Tokyo Electric Power Co. said Thursday based on data obtained by adjusted gauges.

But the plant operator said the water at the bottom of the reactor pressure vessel holding the fuel is keeping the melted fuel cool, assuring that the company is succeeding in preventing the reactor's fuel from overheating by injecting water from outside.

Based on the latest data after workers adjusted gauges for measuring the water level at the reactor, water could not be confirmed inside the pressure vessel at a point 5 meters below where the top of the 4-meter-long fuel rods normally are, according to the utility also known as TEPCO. english.kyodonews.jp

so, we have a complete meltdown and major breach.
by Edano 5/12/2011 10:42:24 AM

@edano - it certainly looks that way, and that revelation comes only a few days after Tepco revised the fuel damage estimate at #1 DOWN from 70% to 50% damaged.

Water leaking from No.1 reactor

Tokyo Electric Power Company says water may be leaking from a hole in the No.1 reactor at the Fukushima Daiichi nuclear plant, causing a sharp drop in the water level inside the reactor.

Tokyo Electric sent workers inside the building to adjust the water gauge of the reactor.

The utility suspected the gauge wasn't working properly because the water level hasn't been rising despite the pumping in of 150 tons of water daily to cool the reactor.

On Thursday morning, it was found that the water level was more than one meter below the bottom of the fuel rods. The water is believed to be leaking into the containment vessel.

Tokyo Electric says temperatures at the bottom of the reactor are between 100 and 120 degrees Celsius, suggesting that the fuel rods have slipped downward and are being cooled in the water below.

The utility says it will continue to monitor the situation by increasing the volume of water being injected.

Chief Cabinet Secretary Yukio Edano told reporters that the reactor appears to be stable because it's been steadily cooled for a long period. But he said the condition of the reactor must be reassessed as some figures from the gauge are contradictory.

The Nuclear and Industrial Safety Agency said that if the latest data is accurate, it seems parts of the fuel rods have melted and accumulated at the bottom of the reactor. But it added that it believes the fuel rods are being cooled.

it is quite obvious that corium has molten out of the vessel into the containment.

@edano it is great to see some new information, have you heard how the sea leak is progressing-or not -as the case may be
by elainekirk 5/12/2011 11:09:53 AM

And here's some more, www.tepco.co.jp the temperatures for #3. Note how in the third column, our old friend the 'bronze phalange' on the RPV, the temp is shooting up again after 2 days of low temps.

@hudebnik what temp is it showing?
by elainekirk 5/12/2011 11:21:06 AM

@hudebnik gah this is ridiculous the accumulated radiation they have pumped into our atmosphere and oceans is past the point where we could have expected little global damage
And trying to tell us chernobyl was worse is not a valid argument they have failed to monitor theirs in any scientifically sound manner , they are still churning it out, and it isn't 'less' than chernobyl it is PLUS Chernobyls, and TMI's they are playing on peoples ignorance a large chunk of this radiation will be with us for many many centuries
by elainekirk 5/12/2011 11:30:48 AM

@edano-yes, good with info, but tell me: how can they say (all the time..) so much contradictive at the same time… and why is people buying this…! “the reactor appears to be stable because it's been steadily cooled for a long period.” – but it’s a leakage and it can’t be stable with a meter water level drop and leak – or what do you say? I would say it’s a big collective blindness –

New radioactive leak raises questions

Highly radioactive water was found leaking into the sea from the damaged Fukushima Daiichi nuclear plant on Wednesday. It's now been revealed that contaminated water levels in the No. 3 reactor's turbine building were already alarmingly high by Sunday.

Tokyo Electric Power Company plugged the leak with concrete after it found highly radioactive water flowing into the sea through a pit.

Radioactive cesium 620,000 times higher than the government-set safety limit was detected from the leaked water.

The contaminated water was streaming from the outlet of a pipe for electric cables.

The leak is thought to have stemmed from pooled water in the turbine building of the No. 3 reactor.

TEPCO says it found that waste water levels in the facility had risen to a point where leakage was feared on Sunday.

The company says it doesn't know when the leak began, but that it will investigate if the monitoring of water levels was appropriate. The problem raises the question of whether the utility wasn't able to prevent the latest leak.

The utility is planning to soon begin transferring radioactive water accumulated in the turbine building to a provisional storage facility. It is now checking for other possible leaks.

Highly radioactive water poured into the sea from a crack in a pit outside the No.2 reactor in early April.
On Thursday, Chief Cabinet Secretary Yukio Edano said the renewed leaking of radioactive materials into the sea was extremely regrettable.

He says the government apologizes to the local residents, the fishing industry and neighboring countries.

Edano also said he had instructed TEPCO to investigate how the leak occurred, and that the company must take measures to prevent another episode.

TEPCO: Highly radioactive water flowed into sea

Highly radioactive water has been found seeping into the ocean near one of the reactors at the damaged Fukushima Daiichi nuclear power plant.

Workers found that contaminated water was flowing from a pipe into a pit near the Number 3 reactor's water intake on Wednesday morning.

The workers then used a camera to film near the water intake pipe. They found contaminated water was also leaking from the wall of the pit into the ocean.

Tokyo Electric Power Company says that water in the pit contained 37,000 becquerels of cesium-134 per cubic centimeter. That represents 620,000 times above the safety limit set by the government.

TEPCO also found that seawater between the intake and a nearby special barrier had the same radioactive substance at 32,000 times the limit. The barrier was set up to prevent radioactive water from spilling into the ocean.

The firm says it managed to stop the leak later in the day after it blocked the pipe and buried the pit in concrete.

TEPCO is looking into the possibility that radioactive water in the reactor's turbine building may have leaked through a tunnel connecting to the pipe because water levels in the turbine building had fallen since Tuesday.

Last month, TEPCO confirmed that radioactive water had leaked into the ocean from a crack in a pit outside the No.2 reactor. It later stopped the leak.

@edano I am swaying towards the notion that they never really considered the ocean out of bounds and the leaks they 'discover' and deal with are nothing more than a 'cover our backs PR ' stunt

@elainekirk : imo they use the ocean intentially to get rid of the radiation. and, as they have an exclusiuon zone, there will be never an evidence how much was let out.

TBS Cam is not working, do we know why? Or happens that more often?
by Mina 5/12/2011 11:44:50 AM

@hudebnik you mentioned a bronze flange in the readings. The melting point on bronze is really really low. We melt bronze for casting with simple tools at the house.
