@fitter Live TEPCO conferences are usually shown here (filmed by an independant journalist): iwakamiyasumi.com and keeping an eye on this page: www.ustream.tv will often catch other NISA/Cabinet Office briefings too. TEPCO seem to like late-nighters (Japan time).

if you look at all the pipe that is destroyed and then looks like they are now blocking acsess to it, electrical would be the same..... they must be working off bare bones in that plant

Gov't officials taking TEPCO posts 'socially unacceptable': Edano

TOKYO, April 13, Kyodo

Chief Cabinet Secretary Yukio Edano said Wednesday he believes that former government officials taking senior posts at Tokyo Electric Power Co. is ''socially unacceptable.''

Over the years, many industry ministry officials have taken highly paid post-retirement jobs at the utility, the operator of the crippled Fukushima Daiichi nuclear power plant.

Since the crisis at the plant, caused by the March 11 deadly earthquake and tsunami, many people have suspected that cozy ties between the Ministry of Economy, Trade and Industry and the power company, known as TEPCO, have prevented Japan from having strict safety control of nuclear facilities.

Edano, the top government spokesman, said at a news conference he cannot overlook that such mistrust is growing among the public, even if close ties between the ministry and the company are not affecting nuclear safety management. More at link english.kyodonews.jp

Edano aware in March that nuke crisis could be raised to worst level

TOKYO, April 13, Kyodo

Chief Cabinet Secretary Yukio Edano said Wednesday he was aware in late March of the possibility that the status of the ongoing nuclear crisis at the Fukushima Daiichi power plant could be raised to the worst level, but the decision did not come until later because of inconclusive data.

Japan's new assessment, raising the crisis to the highest level of 7 on an international scale, was announced Tuesday, about a month after a magnitude 9.0 earthquake and tsunami crippled the plant and caused radiation leaks, fueling widespread criticism that the government has acted belatedly.

The assessment now puts the situation at the Fukushima plant situation on par with the 1986 Chernobyl catastrophe.

Edano told a news conference Wednesday that the Nuclear Safety Commission of Japan said in late March that its crisis assessment estimate was based on limited data. More at link english.kyodonews.jp

@fitter I'm an industrial gas fitter living in Perth Australia working on Industrial gas burners and boilers. I was wondering how a pressure vessel got to twice it's design pressure without blowing it's safety valves. Does anyone know if they ever do accumulation tests on nuclear reactors?
by standbybarry 4/13/2011 10:11:42 AM

@standbybarry Are you asking about the RPV? Safety valves go around 1050psi or around 7MPa

@Angie I'm sorry, but I just don't trust anything TEPCO has to say about the Fukushima nuclear facility, ESPECIALLY when it comes to the status of fuel rods anywhere at that plant.
by James Ward 4/13/2011 11:10:39 AM

@James Ward I do not think most people trust anything out of Tepco.........would like to know though what the class as "most" and what happened to the rest???

@angie: #4 SFP fuel mostly intact ?
From latest JAIF report: "[Tepco] says an analysis of the water from the pool on Tuesday put the radiation level on the surface at 84 millisieverts per hour and the water temperature at around 90
degrees Celsius, higher than usual" Wednesday, April 13, 2011 12:47 +0900 (JST)

"higher than usual" isn't a gentle way to say it's a mess ?
by Jocelyn Mayer 4/13/2011 11:53:41 AM

nice jocelyn.. I wish they would send the robots over and peek in the SFP's and photo graph all the damage..
by dean 4/13/2011 11:56:53 AM

@dean: if they were able to pick some water for analysis, they could have take picture at the same time, don't you think ?

@Jocelyn Mayer Thats why I am still waiting for the rest of the story to be written up! because I think the same thing as you.

TEPCO has changed the page with information about the situation at the Fukushima Daiichi and Fukushima Daini nuclear power plants. New page here: www.tepco.co.jp
by Pedro Jesus 4/13/2011 12:05:00 PM

That report on the #4 SFP seems far better than I thought it would. It had burning rods at at least one point. Wouldn't the radiation levels in the pool be higher than that?

If it leaks, constant new water injection...
by Markfm 4/13/2011 12:07:51 PM

Nobody seem to look closely to #5 & #6 reactors...
No big trouble there, except they leak about 16 cm of water from the RPV every day. If the RPV inside diameter is 7~7.5 meter (don't know the real value), this makes 6 to 7 tonnes of radioactive water leaking every day for each...

@Markfm if new water is diluting the reading and they are using this as evidence things are "better" what is the real info. #4 is leaking, we knew that. There are rods tossed everywhere even by TEPCO's admission. My guess would be back to #3 ejecting rods during the big explosion. Others have assumed this was the case.
by Nancy 4/13/2011 12:16:32 PM

@Nancy : they just want to clean spf #4 as soon as possible to delete all evidences of their weapon enrichment experiments.
by Edano 4/13/2011 12:17:57 PM

@Jocelyn Maybe the 16cm of water turns to steam?
by FradyKat 4/13/2011 12:36:48 PM

I believe they have continued to pump really large amounts of water into SFP4, which means that it is coming back out again. I do not know if they have 7x24 pumping on it, but if not I would hope the measurement (bucket of water) was done prior to injecting more water, at the start of a cycle, as well as perhaps at the end. In a sane world I really would have also expected someone to try to sample near the bottom of the pool (I haven't dug up any description of their test methodology).
by Markfm 4/13/2011 12:37:59 PM

@Jocelyn Unit 5 has looked a little more "active" than Unit 6. It drops water level constantly and the temperature rises until apparently more water is added. I don't know what the normal parameters were, but it looks like it needs constant attention.

by Debra Beckham 4/13/2011 1:07:48 PM

@FradyKat: it's unlikely that water turns into stream, given the low temperature. But even, if water is dropping and steam is generated that would mean that steam is leaking... This would be worse than water leaking: water can be contained, not steam (not easily...)
by Jocelyn Mayer 4/13/2011 1:08:01 PM

@Deirdre: #6 seem to have quite the same behavior as #5. I will compute precisely the leak amount and temperature move for the two, for more comparisons.

Japantimes article indicates the SFP 4 measurement is the opposite of good news: Radiation surges above 4's fuel pool search.japantimes.co.jp "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." "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." "Tepco dumped 195 tons of fresh water onto the rods early Wednesday to stop the temperature from rising. "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."

@Markfm What??? "was being caused by the spent fuel rods or radioactive material leaking from the reactor's pressure vessel." TEPCO has been saying the RPV in 4 was empty and the fuel from it was in the SFP. Is this some sort of slip of the lip? Were they in the process of unloading when the earthquake it?
