Day 382 Tell Prime Minister Noda… “No!”

FYI…

In tomorrow’s morning edition of the Asahi Shinbun, Greenpeace will be taking out an ad asking the people in Japan to send letters to Prime Minister Noda regarding the restarting of the Oi nuclear power plant in Fukui Prefecture. According to a video report of the meeting of the Nuclear Safety Commission of Japan, it took the committee about six minutes to review the report that endorses the results of the reactor’s stress test.

Here is what the ad will look like:

Very high radiation, little water in Japan reactor

By MARI YAMAGUCHI, Associated Press – 6 hours ago

TOKYO (AP) — One of Japan’s crippled nuclear reactors still has fatally high radiation levels and hardly any water to cool it, according to an internal examination that renews doubts about the plant’s stability.

A tool equipped with a tiny video camera, a thermometer, a dosimeter and a water gauge was used to assess damage inside the No. 2 reactor’s containment chamber for the second time since the tsunami swept into the Fukushima Dai-ichi plant a year ago.

The data collected Tuesday showed the damage from the disaster was so severe, the plant operator will have to develop special equipment and technology to tolerate the harsh environment and decommission the plant, a process expected to last decades.

The other two reactors that had meltdowns could be in even worse shape. The No. 2 reactor is the only one officials have been able to closely examine so far.

Fukushima No. 2 reactor radiation level up to 73 sieverts per hour

TOKYO (Kyodo) — The operator of the Fukushima Daiichi nuclear power plant said Tuesday that the radiation dose inside the crippled No. 2 reactor stood at an extremely high level between 31.1 and 72.9 sieverts per hour, underscoring the existence of radioactive substances from the melted fuel inside the structure.

Tokyo Electric Power Co. measured the radiation level by inserting a long dosimeter into the round-bottomed, flask-shaped primary containment vessel, where fuel is thought to be accumulating at the bottom following the nuclear accident last year.

Human beings could die within one month once exposed to 7 sieverts and within several days once exposed to 20 sieverts or more. Usually, when an ordinary reactor is not operating, the radiation level is low enough for workers to enter inside, according to the utility known as TEPCO.

*Yomiuri* Experts: Melted fuel may not be covered in water — Far shallower than assumed — Tepco still claiming Fukushima Daiichi in state of ‘cold shutdown’

Title: Fukushima reactor water level shallower than thought

Source: The Yomiuri Shimbun
Date: Mar. 28, 2012

The water level in the containment vessel of the No. 2 reactor at the Fukushima No. 1 nuclear power plant is only about 60 centimeters deep, far shallower than previously assumed […]According to some experts, it is possible that nuclear fuel that melted through the reactor’s pressure vessel and accumulated on the bottom of the containment vessel in the aftermath of the March 11 earthquake and tsunami may not be completely covered in the water.

[…] The discovery of the unexpectedly shallow water level will not affect TEPCO’s judgment that the reactor is in a state of “cold shutdown.”

73Sv/h in container vessel

Posted by Mochizuki on March 27th, 2012

Videos of endoscope at Daiichi 27 Mar 2012 and read entire article at:

http://fukushima-diary.com/2012/03/73svh-in-container-vessel/

During the endoscope operation of 3/26/2012, Tepco measured the radiation level of inside of container vessel. Tepco published the data the next day, 3/27/2012.

It was measured at 8 points, 50~100cm away from the wall.
The highest reading was 73Sv/h.(100,000 times higher than the radiation level of the container vessel in periodic checkup) Other readings were 31.1~57.4 Sv/h.

In this level of radiation, human starts vomiting within a minute and dies within 8 minutes. It is impossible to have human work inside of container vessel.

Actually, Tepco did not intend to watch the fuel debris in this endoscope operation. Tepco is assuming that the fuel is in pedestal, which is separated from where they checked with endoscope this time with concrete wall. (Like this picture below.)

To see where Tepco assumes the fuel debris is, they have to put the camera under the pressure vessel, surrounded by the concrete of pedestal. About this potential attempt, actual Fukushima worker Happy11311 tweeted like this below.

ただいまっ(^O^)2号機格納容器内の線量はMax73Sv/hってオイラが思ってたより低かったでし。とは言え、人間が近付ける線量ではないけど…。多分ペデスタルの中や入口は1000Sv/h以上あるはずだから今回使った線量計じゃスケールオーバーで測定できないでし。

The highest reading of 73 Sv/h was lower than I thought, but no one can get close to there. Probably it is higher than 1000Sv/h  inside or in front of the entrance of the pedestal. The endoscope used this time can’t resist the radiation of  higher than 1000Sv/h so it would be over scale.

<End>

続き1:まだ燃料デブリは確認出来てないけど今回の調査ではっきりしたの事は東電が計画している格納容器内を水で満たすには相当な時間を要するか、無理だろうって事。あと中長期工程で10年後に燃料取出着手って言ってるけど、それも無理で何年後になるかわからなくなった事でし。

The fuel debris has not been checked yet, but this operation made it clear that it would take considerable amount of time to fill container vessel with water as Tepco is planning, or it would be simply impossible. and they are planning to take out the fuel in 10 years but it would take way more than 10 years. I don’t know how long it takes.

Just In: Suppression chamber “may have been destroyed” at Reactor No. 2 -NHK (VIDEO)

Title: Lethal radiation detected inside Fukushima reactor
Source: NHK
Date: Wednesday, March 28, 2012 11:13 +0900 (JST)

Tokyo Electric Power Company has detected extremely high levels of radiation inside one of the crippled reactors of the Fukushima Daiichi nuclear power plant. […]

SOURCE: Asahi

It says radiation levels increased as the dosimeter was lowered inside the reactor. This suggests the nuclear fuel melted down and collected at the bottom of the vessel.

The utility also learned the water level inside the vessel was only 60 centimeters, compared to the original estimate of about 3 meters.

TEPCO suspects the suppression chamber at the bottom of the vessel may have been destroyed. […]

Fukushima Medical Univ. Researcher: “If People Do Their Own Decontamination, They Can Feel Secure”

The researcher, Shinichi Niwa, is talking about people in Fukushima Prefecture where the soil is very contaminated (probably with the exception of Aizu Region, although even there hot spots or hot areas do exist).

Mainichi Daily reports from the original Japanese article which is about the fear of radiation caused by the accident and how that affected the Fukushima residents. (You can read more on that topic by reading the post about Ms. Emiko Numauchi of Minami Soma City, Fukushima.)

Tepco to delay rate hike by a year for some customers

Kyodo

Tokyo Electric Power Co. will delay its planned electricity rate hike by one year for some corporate customers that are opposed to the increase, after coming under fire for its insufficient explanation on the matter.

The delay may result in Tepco bringing in only an extra ¥300 billion in the next business year, compared with its initial estimate of ¥400 billion, Managing Director Hiroaki Takatsu said Tuesday.

Tepco is planning to raise its rate in April by an average of 17 percent for large-lot customers.

Nuclear Energy Advocates Insist U.S. Reactors Completely Safe Unless Something Bad Happens

MARCH 17, 2011 | ISSUE 47•50 ISSUE 47•11

WASHINGTON—Responding to the ongoing nuclear crisis in Japan, officials from the Nuclear Regulatory Commission sought Thursday to reassure nervous Americans that U.S. reactors were 100 percent safe and posed absolutely no threat to the public health as long as no unforeseeable system failure or sudden accident were to occur. “With the advanced safeguards we have in place, the nuclear facilities in this country could never, ever become a danger like those in Japan, unless our generators malfunctioned in an unexpected yet catastrophic manner, causing the fuel rods to melt down,” said NRC chairman Gregory Jaczko, insisting that nuclear power remained a clean, harmless energy source that could only lead to disaster if events were to unfold in the exact same way they did in Japan, or in a number of other terrifying and totally plausible scenarios that have taken place since the 1950s. “When you consider all of our backup cooling processes, containment vessels, and contingency plans, you realize that, barring the fact that all of those safety measures could be wiped away in an instant by a natural disaster or electrical error, our reactors are indestructible.” Jaczko added that U.S. nuclear power plants were also completely guarded against any and all terrorist attacks, except those no one could have predicted.
