Well-Educated Train Diva

''Excuse Me, Do You Know What Schools I've Been To and How Well-Educated I Am ?''

Update on Hermon Raju, the well-educated screamer commuter on Metro-North : ''We give a lot of credit to the conductor, who keeps her cool during the whole interaction, and doesn't raise her voice once. Best of all, according to the video's uploader there was an announcement on the train a minute later, asking all passengers to please not use profanity on the train, 'especially those people who went to Harvard or Yale or are from Westport.' Pshaw, as if the Crimson elite would deign to follow such commands.''

NRC Issues Warnings About Spent-Fuel Pool, Evacuation Zone in Japan


Nuclear Regulatory Commission Issues Dire Nuclear Warning about Japan ; Radiation Levels Are So High That Evacuation Zone Should Be Larger.

Earlier today, the top nuclear regulator in the United States said that the Fukushima nuclear power plant was more dangerous than being described by the Japanese government.

''Nuclear Regulatory Commission Chairman Gregory Jaczko said the spent-fuel pools at Fukushima Daiichi's Unit 4 reactor may be empty and a crack may be present in the spent-fuel pool for the No. 3 reactor. Without proper cooling, spent-fuel rods will continue to heat and potentially ignite, dispersing radioactive elements and making an already complicated situation evermore difficult to contain.''

More information about the NRC's statement from earlier today :

''... 'We believe that there is no water in the spent-fuel pool known as No. 4, and I would say that it is my great hope that the information that we have is not accurate,' Mr. Jaczko added. 'I would hope for the sake of everyone that the situation is not at the state that we think it is.'

''Meanwhile, Tokyo Electric Power Co., the nuclear plant operator, denied Jaczko's assessment, saying that the "condition is stable" at Unit 4, according to the AP.'' ...

Not only is the U.S. nuclear regulator issuing a more dire warning about the situation at the Fukushima nuclear power plant, but the U.S. is also calling for a larger evacuation area in Japan.

Japan Nuclear Radiation Worries


Since the magnitude 9.0 earthquake and resulting tsunami, Japan has endured a nuclear crisis that has now lead to two explosions at a nuclear power plant.

Moments ago, a new explosion took place at the Fukushima Daiichi nuclear power plant, this time in what has been described as its Unit 3 reactor. YouTube video of the new explosion :


This new explosion follows an earlier explosion in the Unit 1 reactor at the same power plant. YouTube video of that explosion :

The twin disaster is prompting fears about radiation prevention and treatment, including any necessary safety measures that would provide for the public health.

The power plant at Fukushima is approximately 150 miles north from Tokyo. The people living closest to the damaged nuclear power plant had already been told to stay indoors and avoid drinking tap water as a result of the Saturday explosion. Evacuees are being taken to shelters. It is not yet known what other nuclear emergency advisories are being made, or preparations being taken, at other large large cities in Japan. Yesterday, it was also reported that authorities were planning for the distribution of Iodine to residents. (Iodine can be taken to prevent the absorption of radiation by the thyroid, reported MSNBC.)

Japan Earthquake and Tsunami Disaster Toll Underreported

Updated : Official Death Toll Reported to be 1,217


Two Days After the 8.9 Magnitude Earthquake and Tsunamis, the True Extent of the Disaster in Japan is Yet Unknown.

Rescue teams from various countries, including the United States, Great Britain, and numerous other countries, have set out for Japan, to join what is being described as the ''colossal'' effort to rescue survivors of the tripple tragedies of the earthquake, tsunami, and the resulting nuclear emergencies.

Reports of food shortages in Japan continue to grow, not only as a result of the damage to stores, but to transportation and distribution systems.

One emotional story that demonstrates the large scale loss of life is the often-repeated news report that as many as 10,000 people are reported to be missing in the port town of Minamisanriku, after the tsunami swept away large portions of the town.

Adding to the rescue and recovery efforts is the concern about the nuclear emergency taking place at the Fukushami nuclear power plants. The New York Times is finally catching up to the severity of the nuclear fears.

''The emergency appeared to be the worst involving a nuclear plant since the Chernobyl disaster 25 years ago. The developments at two separate nuclear plants prompted the evacuation of more than 200,000 people. Japanese officials said they had also ordered up the largest mobilization of their Self-Defense Forces since World War II to assist in the relief effort.

''On Saturday, Japanese officials took the extraordinary step of flooding the crippled No. 1 reactor at Fukushima Daiichi Nuclear Power Station, 170 miles north of Tokyo, with seawater in a last-ditch effort to avoid a nuclear meltdown. That came after an explosion caused by hydrogen that tore the outer wall and roof off the building housing the reactor, although the steel containment of the reactor remained in place.

''Then on Sunday, cooling failed at a second reactor — No. 3 — and core melting was presumed at both, said the top government spokesman, Chief Cabinet Secretary Yukio Edano. An explosion could also rock the No. 3 reactor, Mr. Edano warned, because of a buildup of hydrogen within the reactor.''

The official death toll, reported to be as low as 800 people, is unrealistic in the face of the evidence of disaster in the coastal town and villages following the dangerous tsunami.

Another example of the underreporting of the extent of the damage is the growing reality that Japan is facing a nuclear emergency. Although more than 200,000 people have been evacuated from danger zones around two atomic facilities in Fukushima, Japanese media and government officials keep insisting that few people have been hospitalised as as result of radiation exposure. And the events at the Fukushima nuclear power plants continue to be irresponsibly described as possible''partial meltdowns,'' in spite of the facts that one nuclear reactor exploded on Saturday and the desperate efforts to cool the damaged nuclear reactor cores at the troubled nuclear power plants with sea water.

Nobody knows what Japan's plans are, in order to keep people safe, should a nuclear meltdown happen.

Meanwhile, the divergence in reporting doesn't end with the fallout of the disaster. Even the size of the earthquake is in dispute. The Associated Press has reported that the Meteorological Agency in Japan upgraded the magnitude of Friday's catastrophic earthquake to 9.0 from its earlier measurement of 8.8. By comparison, the U.S. Geological Survey had measured the earthquake at magnitude 8.9 -- leaving that measurement unchanged as of Sunday.

Background :


Youtube.com - IAEA Director General Briefs Member States and Media on Nuclear Safety in Japan

At 17.45 CET on 14 March 2011, IAEA Director General Yukiya Amano convened a technical briefing on the consequences of the twin natural disasters for nuclear safety in Japan.



Youtube.com - IAEA Director General's Video Update on Tsunami and Earthquake Emergency Response

[12 March 2011, 2000 CET] - IAEA Director General Yukiya Amano released a YouTube video statement on the aftermath of the earthquake and tsunami that struck Japan. Director General Amano noted the current effort to prevent further damage to Unit 1 reactor at the Fukushima Daiichi nuclear power plant. The text portion of the YouTube video indicated that the IAEA was using emergency communication channels to exchange verified, official information between Japan and other IAEA Member States, as well has been coördinating the delivery of international assistance, should Japan or other affected countries request emergency relief.

Japan nuclear meltdown may be underway, CNN reports

Breaking news :

Update : CNN is reporting that spent nuclear fuel rods may have burned in the last disaster to strike the Fukushima nuclear power plant in Japan.

Tokyo (CNN) -- Spent fuel rods containing radioactive material may have burned in Tuesday's fire at the Fukushima Daiichi nuclear plant -- causing a spike in radiation levels, the plant's owner said.

The blaze started Tuesday morning but was later extinguished, Tokyo Electric Power Company said. It was unclear how much radioactive material may have been emitted, or what kind of health threat that could pose.

Chief Cabinet Secretary Yukio Edano said Tuesday afternoon that radiation readings at the plant's front gate had returned to a level that would not cause "harm to human health."

Japanese officials earlier told the International Atomic Energy Agency that radioactivity was "being released directly into the atmosphere" during the fire, according to a statement from the UN watchdog organization.


Official: ''We see the possibility of a meltdown''

12 March 2011 Update : CNN reports that a nuclear meltdown "may be underway" at the Fukushima nuclear power plant. Conflicting reports confuse the real danger that Japan may be facing. An official with Japan's nuclear safety agency announced that a risk of meltdown exists. MIT scientist Jim Walsch said on the CNN news program hosted by Wolf Blitzer that it is too soon to tell if a meltdown is happening. When confronted on live television earlier this evening about the meltdown danger, Japanese Ambassador to the United States Ichiro Fujisaki denied that any meltdown was underway.

"There was a concern about this reactor. We have confirmed that there was a blowup but it was not a blowup of reactor nor container. It was a blowup of the outer building so there was no leakage of the radioactive material," Ambassador Fujisaki told Mr. Blitzer.

Following is the initial CNN breaking news brief :

[5:48 p.m. ET, 7:48 a.m. Tokyo] A meltdown may be under way at one of Fukushima Daiichi's nuclear power reactors, an official with Japan's nuclear and industrial safety agency told CNN Sunday.

A meltdown is a catastrophic failure of the reactor core, with a potential for widespread radiation release. However, Toshiro Bannai, director of the agency's international affairs office, expressed confidence that efforts to control the crisis would prove successful.

Meanwhile, a second reactor at the same facility failed shortly after 5 a.m. Sunday, the Tokyo Electric Power Company said, according to TV Asahi. The power company said it was having difficulty cooling the reactor and may need to release radioactive steam in order to relieve pressure.

A nuclear disaster, indeed, does loom in Japan, as a second nuclear reactor has failed. So far, the most notable official response by Japanese Prime Minister Naoto Kan has been the expansion of the evacuation zone around Fukushima from 10 to 20 kilometers.

Japan nuclear meltdown risk

In apparent desperation to prevent a nuclear meltdown, Tokyo Electric Power plans to use sea water to cool down the nuclear reactor at the Fukushima power plant. The drastic sea water plan may not be working.

Japanese authorities are in a race against time to secure the integrity of the nuclear reactor at the Fukushima nuclear power plant, following a large explosion earlier today.

The large 8.9 magnitude earthquake on Friday in Japan had caused extensive damaged to the Fukushima power plant, leading to the failure of the reactor's critical cooling system. Prior to the explosion, nuclear engineers had been releasing steam from the cooling system in an emergency effort to relieve pressure.

Although some press is reporting that the release of radiation is decreasing, Yahoo! news is reporting that the attempt to use sea water is a sign that Japanese nuclear authorities are scrambling to find a solution to prevent a major nuclear disaster.

"They are working furiously to find a solution to cool the core," said Mark Hibbs, a senior associate at the Nuclear Policy Program for the Carnegie Endowment for International Peace.

Nuclear agency officials said Japan was injecting sea water into the core — an indication, Hibbs said, of "how serious the problem is and how the Japanese had to resort to unusual and improvised solutions to cool the reactor core."

In a subsequent report, The New York Times provided clarity about the last-ditch effort to use sea water to cool the nuclear reactor core : ''... ocean water is likely to permanently disable the reactor.''
