@AustralianCannonball They do matter. If the molten fuel would have completely melted through the RPV down to the CV floor temperatures inside the RPV would drastically decline along with pressure.
by Pedro Jesus 6/1/2011 6:05:59 AM

@AustralianCannonball That is still the mystery. Some computer simulations tell us that molten nuclear fuel should by now be sitting at the bottom of the CV if not melting their way through it... but the temperature and pressure readings tell a different tale. We need more information.
by Pedro Jesus 6/1/2011 6:07:42 AM

@AC,Pedro, they are not sure why temp is huge. It could be that the corium has pocketed steam or hydrogen up there. What ever it is, it keeps rising, and something is gonna give at some point !!!!!! That will mean that the top of the RPV will be breached directly to the outside...

World News Japan pensioners volunteer to tackle nuclear crisis By Roland Buerk BBC News A group of more than 200 Japanese pensioners are volunteering to tackle the nuclear crisis at the Fukushima power station.

The Skilled Veterans Corps, as they call themselves, is made up of retired engineers and other professionals, all over the age of 60.

They say they should be facing the dangers of radiation, not the young. axisoflogic.com

@tenzing do you get the feeling that these men are fighting the battle guided only by disembodied voices transmitting from far flung offices?

NISA urges TEPCO to set policy for decontamination
Japan's Nuclear and Industrial Safety Agency is urging Tokyo Electric Power Company to lay out its plans for decontaminating the radioactive water that continues to accumulate at the Fukushima Daiichi nuclear plant.
TEPCO says the heavy rain until Tuesday has increased the volume of highly radioactive water inside the plant.
The utility says the level of radioactive water rose by 6.2 centimeters in an underground tunnel extending from the No.2 reactor building during the 24 hours through Wednesday morning.
In the basement of the reactor's turbine building, the water rose by 6 centimeters.
Water levels also rose by more than 2 centimeters in the tunnel of the No.3 reactor, and in the basement of the reactor's turbine building.
The government's nuclear safety agency is asking TEPCO to secure new storage sites to which the contaminated water can be quickly transferred, and to lay out its plans for decontamination.
It is asking the utility to come up with the plans later on Wednesday, as the rainy season is approaching, bringing increased risks that the water will seep out.
Contaminated water is already flooding the basements of the turbine and reactor buildings, partly due to water injections to cool down the reactor cores.

HHi @elaine - very quiet today
by hudebnik 6/1/2011 8:25:41 AM

@hudebnik they seem to label anything 'bad' as equipment malfunction www.tepco.co.jp
by elainekirk 6/1/2011 8:28:25 AM

Tsunami was ocean's equipment malfunction, ocean not Tepco equipment.

@elaine - well clearly these unwelcome anomalies can't be true!
by hudebnik 6/1/2011 8:33:43 AM

@rob tsunami is a natural event the planet has existed since time immemorial under the rule of nature and man is well aware of her potential

@elaine - especially after the near-identical one in 2004

@hudebnik yes! Oh look at #3 is she partying or what!!

Maybe after the tsunami of (bad) news the past week or so we has now reached a sort of stasis, with few new things to be revealed. Unless things enexpectedly change, that is.
by hudebnik 6/1/2011 8:38:27 AM

@elaine - #3 has been spectacularly unstable all the way through. I have the strong impression that the big peaks in mid May coincided with the big steam events
by hudebnik 6/1/2011 8:40:04 AM

OK, work to do - may see you all later. Bye!

Naoto Kan Calls Opposition Chief ‘Prime Minister'
Probably the last thing embattled Prime Minister Naoto Kan wanted to do Wednesday was give opposition politicians urging his resignation the gift of the gaffe.

In the end, during a parliament showdown with the main opposition leader, it wasn’t the last thing Mr. Kan did, it was the first.
Mr. Kan tripped right out of the gate during Wednesday’s rowdy debate, the first time the pair have squared off in parliament since the earthquake and tsunami struck, accidentally calling the Liberal Democratic Party’s president Sadakazu Tanigaki “prime minister.”

IAEA: Japan underestimated tsunami impact

A team from the International Atomic Energy Agency will submit a summary of its report to the Japanese government on Wednesday after concluding its investigation into the nuclear disaster in Fukushima.

The 18-member team inspected the damaged Fukushima Daiichi nuclear plant and other nuclear facilities in Japan from May 24th.

The draft of the IAEA summary report says Japan took the best possible measures immediately after the accident at the Fukushima Daiichi plant, but it underestimated the danger of tsunami. The draft says it is hard to expect that Japan could have done more than it did soon after the accident occurred, with all safety systems lost and with insufficient manpower and lighting.
But the draft says Japan underestimated the impact of the tsunami and failed to respond to waves that were higher than had been expected.

It also says the chief characteristic of Japan's worst nuclear accident is that 4 reactors were exposed to the risk of meltdowns.

The report calls on Japan to revise its current process of dealing with a severe nuclear accident. This process is based on the assumption that lighting and electricity would be available in such an accident.

The team criticizes Japan for failing to ensure the independence of the Nuclear and Industrial Safety Agency, despite the advice given 3 years ago by the IAEA that the agency should be separated from the Economy, Trade and Industry Ministry.

The team will submit a full report to an IAEA ministerial meeting that will open on June 20th in Vienna.

there is an interesting detail: "It also says the chief characteristic of Japan's worst nuclear accident is that 4 reactors were exposed to the risk of meltdowns." what is the 4th reactor ?
by Edano 6/1/2011 9:39:40 AM

@edano I go for #4 or #6
by elainekirk 6/1/2011 9:41:22 AM

I think they include number 4, without realizing that it was under maintenance at the time of the quake.
by FradyKat 6/1/2011 9:42:30 AM

it depends on how to interprete "meltdown". the german word for it, "Kernschmelze" refers clearly only to pressure vessels.
