Day 337 Lord almighty, I’m burning a hole where I lay

It’s at 78, no, 82!

No, that’s not the latest yen-to-dollar exchange rate. It’s the temperature at the #2 reactor.

Last night at 10:18 pm:

*JUST IN* Nikkei: Reactor No. 2 hits 78.3°C — Melted fuel may be moving inside RPV -Tepco

Nikkei report published at 9:55pm ET tonight,

Fukushima nuclear plant 2 the pressure container of the machine, it rises to 78.3 degrees
The highest value of the cool temperature stop rear

Tokyo Electric Power announced that 12th morning, Fukushima 1st nuclear power plant 2 temperature of pressure container bottom of the machine same day at 10 o’clock in the morning rose in Celsius 78.3 degree. According to Tokyo Electric Power Company, value of this temperature in the December last year later cool temperature stopped state is declared, reaches the highest value.

You call 2 the thermometer of remainder that it is transitive at approximately 35 degrees.

2 temperature of machine pressure container bottom rose entering February, but once it had decreased to approximately 65 degrees by increasing the pouring water quantity for cooling. But, 11th in the afternoon again in Celsius 74.9 degree rise. In the 11th night the pouring water quantity per hour was made 1 ton increasing and the same 14.6 tons. As for Tokyo Electric Power Company, because you cannot see the effect of cooling, you say that modification of the pouring water quantity is examined.

EX-SKF has the press conference details:

[…] TEPCO do not give morning presser on weekends any more, but today is the exception due to the concern over the Reactor 2 RPV. Matsumoto is doing the press conference, instead of the usual junior manager of PR department.

Q: What happens if the temperature here exceeds 80 degrees Celsius?
A: Further increase of water to be injected into the RPV. But the cold shutdown state should take other parameters of the reactor into consideration.

Q: Possible causes?
A: Unstable cooling at the location. Some movement inside RPV of melted fuel, possibly, disturbing the flow of water. We don’t think it’s likely because we haven’t been working near the reactor. Instrument failure is another possibility. […]

Fukushima Reactor 2 RPV Bottom Temperature at 82 Degrees Celsius 


Decision was made at 2:20PM that the the condition of “the temperature at the bottom of the Reactor Pressure Vessel at 80 degrees Celsius and below” was not met; the condition is specified in the safety regulations.

The temperature at the No.2 reactor of the Fukushima Daiichi nuclear power plant keeps rising even after the injection of more cooling water on Saturday night. […] 

TEPCO is set to dump in boric acid to prevent any nuclear criticality later on Sunday and increase the volume of cooling water by 3 tons per hour.

Under new guidelines, the company must keep reactor temperatures at 80 degrees or below, given thermometers’ margin of error of up to 20 degrees.

And then, perhaps, above 90 degrees Celcius…

(Updated) TEPCO Press Conference on Reactor 2 RPV Temperature

TEPCO’s Matsumoto opening remarks:

No Xe-135 detected in the latest gas sampling test.
Preparing to increase water.
1090 kilograms of boric acid solution has been poured into the RPV.

At 2:20PM, the temperature exceeded 80 degrees Celsius.
Since other temperatures at the bottom of the RPV remain low and the temperature of the Containment Vessel is not rising, the cold shutdown state remains.

(There are many reporters this time…)

It’s the blue line in the chart (screen capture):

TEPCO thinks it is physically “very difficult” for the temperature to rise above 80 degrees Celsius, and it is likely to be the instrument failure.

No cesium-134 and 137 have been detected, so there is no steam being generated inside the RPV/CV.

Graph generated from the automatic digital reading showing 10 degrees “noise” starting 12 noon (before noon, the noise was 1 degree):

Asahi Shinbun’s reporter asked how high exactly the temperature went, as the graph seemed to show the spike above 90 degrees Celsius.

Yet TEPCO reminds us that it’s not important:

Fukushima No. 2 reactor temperature up to 82C, but not critical: TEPCO

TOKYO (Kyodo) — Tokyo Electric Power Co. said Sunday the temperature at the bottom of the No. 2 reactor at its crippled Fukushima No. 1 nuclear plant rose further to 82 C, but the reactor has not gone critical.

While the thermometer reading at shortly after 2 p.m. marked a new high since the reactor attained a cold shutdown in December, the utility known as TEPCO said it has confirmed that sustained nuclear reactions are not taking place in the reactor as no radioactive xenon has been detected inside its containment vessel.

TEPCO reported the latest development immediately to the Nuclear and Industrial Safety Agency of the Economy, Trade and Industry Ministry as the temperature exceeded the limit of 80 C designated by the company’s safety regulation for maintaining a cold shutdown, it said.

Because it “BELIEVES”!

NHK: Tepco “believes” Reactor No. 2 is in a state of cold shutdown (VIDEO)Title:

Temperature inside No.2 reactor rises again

Date: Saturday, February 11, 2012 21:59 +0900 (JST)

Tokyo Electric Power Company says the temperature inside the No.2 reactor at the damaged Fukushima Daiichi nuclear power plant has risen again.

[…] to around 71 degrees Celsius from Friday night to Saturday morning. […]

TEPCO says it will continue to monitor the situation closely as it believes the reactor is in a state of cold shutdown. But the utility says it will consider pouring more water in if the temperature rises further.

Nobel laureate, citizens call for abolition of nuclear power

TOKYO (Kyodo) — An antinuclear civic group led by Nobel literature laureate Kenzaburo Oe and other celebrities held rallies in Tokyo and Niigata Prefecture on Saturday calling for the abolition of nuclear reactors in the aftermath of radiation leaks at the Fukushima No. 1 power plant.

Addressing the protesters gathered at Yoyogi Park in Tokyo, who numbered around 12,000, according to the organizers, Oe insisted on the abolishment of nuclear reactors.

“We will be handing nuclear waste generated from the nuclear reactors to our grandchildren. This is unethical conduct,” Oe said.

The rallies were held as part of the group’s campaign to collect 10 million signatures against nuclear power to submit it to the prime minister and the chiefs of both chambers of the Diet. The executive committee for the “10 Million People’s Action to say Goodbye to Nuclear Power Plant” campaign said earlier it has gathered about 4 million signatures so far in sympathy with its goal to abolish all 54 commercial reactors in Japan.

Taro Yamamoto, an actor who is known as an anti-nuclear advocate, also took part in the rally.

“If a massive earthquake occurs now, our country will be finished. We cannot have the nuclear reactors resume their operations,” he told the protesters.

On March 11, the first anniversary since the disastrous earthquake and tsunami prompted the worst nuclear crisis since Chernobyl at Tokyo Electric Power Co.’s Fukushima No. 1 Nuclear Power Plant, the group plans to hold a rally in Koriyama in Fukushima Prefecture.

TEPCO provided radiation map to U.S. before Japanese public

TOKYO (Kyodo) — Tokyo Electric Power Co. provided a contamination survey map of its crippled Fukushima No. 1 nuclear plant to the U.S. nuclear regulator nearly a month before its official disclosure to the public in Japan in late April last year, company officials said.

The revelation follows a series of revelations that the government data from the System for Prediction of Environmental Emergency Dose Information and the Japan Meteorological Agency’s data on the projected radiation spread were provided to the United States and other international institutes before disclosure of the information in Japan.

TEPCO started making the map which described the amount of radiation at up to 150 spots around the buildings in the power plant site on March 22 and provided it the same day to the U.S. Nuclear Regulatory Commission at the request of its staff members dispatched to Japan after the March 11 earthquake and tsunami triggered the nuclear crisis, the officials said.

Director Hidetaka Inazuka, known for his documentary on the late double atomic bomb survivor Tsutomu Yamaguchi, has turned his attention toward Fukushima Prefecture, covering the prefecture in a new film on people exposed to radiation from the crippled Fukushima No. 1 Nuclear Power Plant.

The 61-year-old filmmaker’s new work is titled “Fukushima 2011: Hibaku ni Sarasareta Hitobito no Kiroku” (Fukushima 2011: Records of people exposed to radiation). It follows survivors of the atomic bombing of Hiroshima and Nagasaki who are now living in Fukushima, as well as the people facing radioactive contamination of their hometowns. The film is due to be screened across Japan from mid-March. It will also be shown at the Los Angeles Japanese Film Festival in April.

Futaba-machi Mayor on March 12, 2011 Explosion of Reactor 1: “Insulation Materials Falling Like Large Snowflakes. I Knew We Were Finished”

Mayor Idogawa says he knew it was the end.

Journalist Hiromichi Ugaya compiled a togetter of the press conference by the mayor of Futaba-machi on February 11, 2012.

Futaba-machi is where part of Fukushima I Nuclear Power Plant is located (Reactors 5, 6). The town’s function has been moved to Kazo City in Saitama Prefecture, and the mayor, Katsutaka Idogawa, is now demanding that his town of about 7,400 residents be relocated instead of “decontaminated”.

Ugaya says Mayor Idogawa held three separate press conferences, one for TV, one for newspapers, and one for independent journalists. I haven’t looked carefully yet, but I don’t see any coverage at the websites of major newspapers.

Mayor Idogawa said:

  • There was no instruction from the government as to where to evacuate, or how to evacuate.
  • The town was not told of the vent, and the vent was carried out while there were lots of people still in town.
  • What looked to be the insulation materials from the plant fell like snowflakes on them, and he knew they were finished.
