11 m3 of nitrogen gas discharged from reactor1 and 2 every hour
Posted by Mochizuki on September 22nd, 2013 · No Comments
“Steam” is repeatedly observed coming up from the top of reactor3.
This July Tepco suggested it may be the Nitrogen gas injected to reactor3. (cf, [Steaming reactor3] Tepco “The steam may be from the inside of the reactor, a certain volume of N2 gas is missing” [URL])
About reactor1 and 2, Tepco stated 11 m3/h of Nitrogen gas is also discharged from the reactors in the press conference of 9/18 and 9/20/2013.
It’s 9 m3/h from reactor1 and 2 m3/h from reactor2 at the moment of this September. It means Tepco injects Nitrogen gas into reactor1 and 2 but the output of Nitrogen gas is less than input by 11 m3/h in total.
It’s assumed to be extremely radioactive but it’s leaking to the atmosphere unfiltered.

In the press conference of 9/18/2013, Tepco announced one tank of the flange type costs tens of million yen to build.
The tank that experienced 300m3 leakage is called “flange type”. It’s quicker to build, but it can easily leak the contaminated water because it’s not welded. However, the specific leaking point hasn’t even been identified. There are 350 tanks of this type in Fukushima nuclear plant.
Tepco commented they can’t reveal the detailed costs of building a flange type tank.

In the press conference of 9/18/2013, Tepco’s spokesman commented all those 8 damages are at 66m height from the ground.
The stack is shaped as quadrangular prism. 8 damages are on every aspect of the 66m area from the ground.
Tepco hasn’t announced the cause.
10 Sv/h stack damaged by debris blasted from reactor1 in 311 / Starting to rust already

On 9/20/2013, Fukushima Diary reported 8 damages were found on the stack for reactor1 and 2.
(cf, 8 damages found on the stack for reactor1&2 / 66 m from the ground [URL])
In the press conference of 9/18/2013, Tepco’s spokesman commented there is another damage on the stack.
The damaged part is below the 8 damaged reported, started rusting already.
According to Tepco, a piece of debris was blasted by reactor1 explosion in 311, and it hit the part of the stack.
None of the scale of the damage nor the seismic effect to the stack has been published.

Following up this article..Tepco president “Water gauge is not installed to all the tanks, water level to be checked by thermography” [URL]
Having contaminated water tanks leaking, Tepco’s president stated they were going to investigate the water levels of each tank on 8/26/2013.
However in the press conference of 9/18/2013, Tepco commented they hadn’t started the investigation yet.
President’s statement can be considered to be just a performance to avoid the further criticism.
[Tritium spread] 310,000 Bq/m3 of Tritium detected in the forest of downstream from 300m3 leakage tank
Posted by Mochizuki on September 21st, 2013 · No Comments
According to Tepco, high level of Tritium (310,000 Bq/m3) was measured in the groundwater of the forest.
The forest is located in the east of the tank area that experienced 300m3 leakage. It’s also located in the west of the groundwater bypass wells.
Detecting high level of Tritium between the leaked tank and the groundwater bypass wells suggests leaked Tritium is traveling toward the wells with groundwater stream.
On 9/13/2013, Tepco’s vice president admitted Tritium met groundwater flow. At this moment, they have no clue to stop the Tritium penetration.
(cf, Tepco’s vice president “Tritium got into groundwater certainly” [URL])
Leaked 300m3 leakage possibly penetrated underground just beside the tank / 1.7 mSv/h in 30cm deep underground
Posted by Mochizuki on September 21st, 2013 · No Comments
On 9/20/2013, Tepco released the boring core analysis data around the 300m3 leakage tank.
From their data, the ground is contaminated in 20 ~ 30cm depth. The highest contamination level was 1.7 mSv/h in 30cm underground.
The leaked tank is situated on 20cm thickness of the concrete base, but the leaked water possibly penetrated underground immediately after the leakage.
Japanese gov started asking for the international advice for contaminated water issue

Following up this article..JP Gov “There is no technology to remove Tritium from contaminated water”/Appeal international world for technology [URL]
Ministry of Economy, Trade and Industry opened the website titled “Request for Information (RFI) for Contaminated Water Issues”.
They have no technology to settle down the contaminated water related problems at this moment. Japanese government accepts domestic / international advice until 10/23/2013.
They mainly seek solutions for the contaminated water storage, Tritium removal technology, decontamination of seawater, understanding and shutting down the groundwater flow.

In the press conference of 9/20/2013, Tepco commented the loosened bolts are inside of the tanks.
From the beginning, it is not designed to be able to maintain from the outside. This means Tepco cannot tighten the bolts of other tanks either.
There are 350 tanks of the same type in Fukushima nuclear plant.
Radiation level of the damaged stack is 10 Sv/h

Friday Humor: "So Where Is This 0.3 Square Kilometer?" PM Abe Asks TEPCO on #Fukushima I Nuke Plant Visit
Prime Minister of Japan was talking about his own "0.3 square kilometer" of the harbor where the "effect" of contaminated water is supposedly completely contained, according to none other than himself. (Even TEPCO was baffled at his comment.)
That's what the national government "at the forefront" is, in reality.
From Kyodo News (9/20/2013):
汚染水の影響範囲知らず発言か 首相「０・３平方キロはどこ？」
So he didn't know the extent of the effect of contaminated water? "Where is the 0.3 square meter?" asks PM
東京電力福島第１原発の汚染水問題をめぐり、安倍晋三首相が１９日に現地を視察した際、放射性物質による海洋への影響が抑えられていると説明する東電幹部に、「０・３（平方キロ）は（どこか）」と尋ねていたことが２０日、分かった。
It was revealed on September 20 that Prime Minister Shinzo Abe had asked "(Where) is the 0.3 (square kilometer)?" to the TEPCO management at Fukushima I Nuclear Power Plant on September 19, as they explained to the prime minister how the effect of radioactive materials on the marine environment is contained.
首相は東京五輪招致を決めた国際オリンピック委員会（ＩＯＣ）総会で「汚染水の影響は港湾内０・３平方キロの範囲内で完全にブロックされている」と説明していたが、実際の範囲がどの程度か理解しないまま発言していた可能性がある。
At the General Meeting of the International Olympic Committee (IOC) which voted for Tokyo, Prime Minister Abe explained "The effect of contaminated water is completely blocked within the 0.3 square meters of the plant harbor." He may have been saying it without knowing the actual extent [of the effect of contaminated water].
安倍首相は東電の小野明所長から放射性物質の海への流出や海中での拡散を防ぐ対策の説明を受けた際に「０・３は？」と質問した。
Prime Minister Abe was briefed by TEPCO's Plant Manager Akira Ono on the countermeasures to prevent radioactive materials from leaking into the ocean and spreading in the ocean, when he asked "Where is 0.3?"
Speaking of a farce, PM Abe wore a protective suit with his name printed wrong ("安部" instead of "安倍", both of which reads "Abe"), and Abe's supporters are indignant (like the political commentator quoted in ultra pro-LDP Sankei Shinbun's magazine), accusing TEPCO of this egregious, disrespectful mistake.
According to the Sankei's magazine that carries the photo below, it was not just disrespectful but "it cast doubts over TEPCO's crisis management skills".

Big deal. Clearly Mr. Abe didn't make a fuss over the wrong character and wore the suit.
What's funnier to me is that Abe wore the name tag that declares he's the Prime Minister. As if that matters in dealing with the problems that have been constantly cropping up at Fukushima I Nuclear Power Plant since the day 1 of the accident.
At least, the name tag on the back of Abe's protective suit had the character correct .......

In this session of IAEA, researcher Aoyama from Japan Meteorological Research Institute reported Cesium-137 discharged from Fukushima nuclear plant travels to the east in the Pacific. Then it comes back to the offshore of Philippines and Indonesia.
After it moves to the east in the Pacific again around the equator, it comes down to Tasman sea.The contaminated water current is estimated to come to the east coast of Australia and Papua New Guinea in 0~200m depth of the sea.
This simulation is based on the the pathway of weapons tests deprived Cs-137 in the North Pacific ocean.

In this session of IAEA, researcher Aoyama from Japan Meteorological Research Institute also reported Cs-134 concentration sank over 200m in the Pacific from Oct. 2011 to June. 2012.
From the report, approx. the highest density of Cs-134 was detected in 0~100m deep in the Pacific in Oct. 2011. However, it moved to 300~400m deep in the Pacific in June. 2012.
This means as times passes, the radioactive material sinks deeper under the sea. Samples taken from the surface of the sea doesn’t indicate the actual contamination.
Steam found coming up from the top of reactor3 again / Reason is not verified yet
Posted by Mochizuki on September 20th, 2013 · 2 Comments
Fukushima Diary reported steam was found coming up from the top of reactor3 on 9/17/2013.
(cf, [Steam after typhoon] “Steam” observed from the top of reactor3 again / humidity was only 53% [URL])
According to Tepco, the “steam” was observed coming up from the same location of reactor3 around 8AM of 9/18/2013 again. It wasn’t seen by 10AM.
In the secretariat meeting for Fukushima decommissioning on 8/29/2013, Prof. Yamana from Kyoto University Research Reactor Institute stated Tepco needs to investigate what is actually discharged as the “steam” such Tritium. However, no analysis data has been published yet.
(cf, Kyoto Uni Prof. “Tritium might be discharged directly from the reactor3 to the atmosphere” [URL])
8 damages found on the stack for reactor1&2 / 66 m from the ground
Posted by Mochizuki on September 20th, 2013 · No Comments
According to Tepco, 8 points of the stack for reactor1&2 have the ruptures and rust.
The stack was used for venting in 311. It’s 120m tall and the damages were found at 66m point from the ground.
The stack has 440 joint parts. 8 parts of them are cracking, slipping and rusting.
M5.8 hit Fukushima plant area on 9/20/2013, but Tepco states it’s unlikely that the stack gets collapsed due to the damages.
They also stated the damage was caused by the earthquake of 311, not deterioration because of the high level of radiation.
