Asahi Newspaper in Japan Confirms Core Meltdown May Have Occurred at Fukushima

Asahi Newspaper in Japan confirms core meltdown may have occurred at Fukushima reactors #2 & #3. 


The information shows that, at the time of the problem in March, when TEPCO was saying that there was no meltdown, as of information on May 16, it may have melted down. The Japanese is ambiguous. 


In keeping with responsible reporting on this accident, the facts, once verified must be reported. So, a meltdown may have occurred, but, according to data from TEPCO on the date of the incident and soon after the incident, there was no way to verify nor deny any meltdown. The final paragraph of the news story shows how this incident unfolded. 


Asahi Shinbun (3:01AM JST 5/17/2011):
東京電力福島第一原子力発電所の2、3号機でも炉心溶融が起こり、原子炉圧力容器の底に燃料が崩れ落ちるメルトダウンが起きていたとみられること が、16日に東電が公表したデータで裏付けられた。3号機では溶けた核燃料がさらに下の格納容器内に落ちた恐れもある。専門家は事故直後から指摘してお り、細野豪志首相補佐官も16日の会見で2、3号機でのメルトダウンの可能性を示唆した。

The data disclosed by TEPCO on May 16 shows that core meltdown may have occurred in the Reactors 2 and 3 at Fukushima I Nuclear Power Plant. In the Reactor 3, the melted fuel may have dropped to the Containment Vessel. Nuclear experts have pointed to the possibility [of meltdown in the Reactors 2 and 3] and Prime Minister's Assistant Goshi Hosono hinted at the possibility in the May 16 press conference.
 東電が4月17日に示した工程表は、6~9カ月で原子炉を安定した状態で停止させるとした。1号機に続き2、3号機でもメルトダウンの可能性が出てきた ことにより、工程表の大幅な見直しは必至だ。炉心を冷やすシステムづくりに時間がかかり、高濃度の放射能汚染水の処理も膨大になるからだ。
According to TEPCO's "roadmap" on April 17, it was going to take between 6 to 9 months to shut down the reactors. The revision of the "roadmap" will be inevitable now that both Reactor 2 and Reactor 3 may have had a meltdown, as it will take more time to build a cooling system for the reactor core, and the massive amount of highly contaminated water will need to be processed.
 今回公表された地震直後のデータは原発内の中央制御室にあり、電源復旧に時間がかかったことや、記録紙に放射性物質が付着しているため整理に時間がか かっていた。公表されたのは、記録紙に打ち出されたグラフや当直長がつける運転日誌などで、大型ファイル4冊分にあたる。
The data disclosed on May 16 was the data right after the earthquake on March 11. It took TEPCO some time to retrieve the data from the central control room of the plant because of the long period of power outage and the radioactive materials on the recorded printout. The data in 4 large binders includes graphs on the printout and operation diaries kept for each shift.
 データによると、圧力容器内の圧力が、2号機は3月15日午後6時43分に、3号機は3月16日午後11時50分に、それぞれ下がった。圧力容器の密閉性が損なわれ、圧力が抜けたとみられている。
According to the data, the pressure inside the Reactor 2 RPV (Reactor Pressure Vessel) dropped at 6:43PM on March 15 (JST), and the pressure inside Reactor 3 RPV dropped at 11:50PM on March 16. The integrity of the RPVs were compromised, it is thought, and the pressure went down.
 圧力容器の底には制御棒や計測機器を外から通すための数多くの貫通部がある。メルトダウンした核燃料が圧力容器の底にたまり、その熱の影響で機器が溶け るなどした結果とみられる。3号機内の汚染水からは、原子炉内の核燃料が損傷して出るテクネチウムなどの放射性物質も確認されていることから、溶けた燃料 がさらに圧力容器から格納容器内に落ちた可能性もある。
There are many channels that go through the bottom of the RPV [16 centimeters thick] to insert control rods and measurement devices. The melted fuel went down to the bottom of the RPV, and may have melted the devices at the bottom. The contaminated water from the Reactor 3 has been found to contain the radioactive materials like technetium that are produced when the nuclear fuel gets damaged, indicating that the melted fuel may have dropped from the RPV into the Containment Vessel.
 東電は会見で「プラント全体の事象を追いかけられておらず、評価できていない」と明確な判断を示さなかった。
In the press conference, TEPCO refrained from saying anything definite. "We haven't fully grasped the situation at the plant, and we haven't been able to evaluate it."
 一方、細野氏は会見で炉心に水が入らなかった時間について「1号機は14時間9分、2号機は6時間29分、3号機は6時間43分と短くない」とし「炉心の完全な溶融(メルトダウン)の可能性をみておかないといけない」と話した。
PM Assistant Hosono said that there was no water being poured into the Reactor 1 for 14 hours and 9 minutes, Reactor 2 for 6 hours and 29 minutes, and Reactor 3 for 6 hours and 43 minutes. He said "We should be prepared for the possibility of the complete meltdown of the reactor core."
 また原子力安全委員会の班目(まだらめ)春樹委員長は16日の定例会後の会見で「3月下旬に2号機で高濃度汚染水が発見された時点で、メルトダウンして いたという認識があり、助言した。1号機と3号機も、事故の経緯を考えると同じことが起こっているとの認識を持っていた」と語った。
Haruki Madarame, chief commissioner of the Nuclear Safety Agency spoke after the regular meeting of NSA on May 16. "When the highly contaminated water was found coming from the Reactor 2 in late March, we recognized that the reactor had had a meltdown, and advised [the government]. We also knew that the Reactor 1 and 3 had the same situation, looking at how the accident unfolded."
 東電によると、機器の記録から、運転中だった1~3号機は地震によっていずれも自動停止。配管の破断などの兆候はみられないとしている。非常用ディーゼ ル発電機も正常に起動していたという。東電はこれらの記録や地震計のデータをもとに、地震直後は機器が正常に作動し、津波到達までは大きな損傷はなかった とみている。(中村浩彦、佐々木英輔)
According to TEPCO, based on the records, the Reactors 1, 2 and 3 stopped automatically after the quake, and there was no sign of any physical damage to the reactor. Emergency diesel power generators were working. TEPCO concluded that all the equipments were working normally after the quake and there was no major damage to the plant until the tsunami hit.

Japan Nuclear Disaster Update & Strong Criticism of Western Media Sensationalism

The western media is having a field day with the nuclear accident in Japan. If you believe them, you'd think all of Japan were underwater and that we are all about to die. This sort of crass sensationalism is a damned disgrace and you should be very skeptical of what these idiots are telling you. The guys working in the news are wishing for big stories. If they can't get them, they make them.
THE PLATTERS - THE GREAT PRETENDER
Remember my Golden Rule about TV: "90% of everything you see on TV is bullshit; the other 10% are commercials."


Actually, it astounds me that people do accept what what the media says as gospel truth. Don't forget that this is the very same media that told us 3 years ago that Swine Flu was going to kill more than 50 million people worldwide. This was the same media that told us that the USA had to invade Iraq because of Saddam's nooklar weapons. This was the same media that told us that SARS also was a killer virus that was going to wipe out entire populations. This was the same media that told us that Bird Flu was going to do the same.


As of today, worldwide deaths from Swine Flu: 82. No nuclear weapons for Saddam (if he had any, do you really think we would have invaded Iraq?). Worldwide deaths from SARS: 100. Worldwide deaths from Bird Flu: 80. Don't even get me started on Man Made Global Warming!


Fact of the matter is that this is the same media who constantly exaggerates stories in order to sell advertising space to an extremely gullible public. When will people ever learn? If history is any example then the answer is: Never. They'll never learn.


Just wait a year or three for the next killer disease and we can start all over again. 


Now, I want to dissect and destroy one clown in particular who has been spreading wild misinformation about the nuclear accident in Fukushima. Mr. Gregory Jaczko head of the Nuclear Regulatory Commission (NRC). Mr. Jaczko should resign his post immediately for incredibly irresponsible rumor mongering concerning a very serious situation. If anyone should be refraining from making wild , unfounded remarks, you'd think it would be the head of the NRC. But, no, I guess this guy is a good example of how people first got the idea of a stark raving mad scientist. I will print for you some of his comments then I will take them apart and show you what balderdash this is. You decide for yourself if this guy is rational or not.


Here are some of Mr. Jaczko's remarks from the NY Daily News:


"So much radiation may have leaked at the Fukushima Daiichi plant that workers may not be able to get close enough to fix it, said Gregory Jaczko, head of the Nuclear Regulatory Commission (NCR)."
Are you kidding me? "So much radiation may have leaked?" Well, so much radiation may not have leaked. "Workers may not be able to get close enough to fix it." Well, workers may be able to get close enough to fix it... Hell, I may win the lottery one day if I keep buying lottery tickets. Ahem, don't look now but, if workers couldn't get close to the reactor, then why is it that two days ago there were only 50 workers at the plant, today there are 180?
"We believe that radiation levels are extremely high, which could possibly impact the ability to take corrective measures," Jaczko said.
Here again he says something stupid again, "We believe that radiation levels are extremely high..." We believe? Really, Mr. Jaczko? You are the head of the NCR and you "believe"? Are you telling me that you are shooting off your mouth and you don't have any facts? How about facts? Here are the facts for you, sir.
He said all water had apparently boiled away from the cooling pool at Reactor No. 4, where 1,097 tons of spent fuel rods are stored.
Apparently!? Here he is completely talking out of his hat. When I first read this I searched the Japanese language news for this story. Couldn't find any verification of it at all. Now where did this dummy get this info? Obviously it's what he wants to believe. Well, I want to believe in the Easter Bunny too but he ain't turning into reality except in little children's minds.
"I hope my information is wrong. It's a terrible tragedy for Japan," Jaczko said.
Great. Just great Mr. Jaczko. You go and freak out a hundred thousand people and cause the US government and Japan millions of dollars in expenses and damages shooting off your mouth and you "hope your information is wrong"!? Well, I hope the Dodgers win the pennant this year. But, in my case, if they don't, at least the US taxpayer won't be on the hook. The only thing you've said so far that isn't stupid is "It's a terrible tragedy for Japan." Yes it is and there's a bunch of people without food and shelter. You blabbing this sensationalist crap is taking people's eyes off the real crisis on the ground. Those people need help.
Jaczko: "I believe the sky may be falling."

This guy just doesn't stop. Mr. Drama Queen, er, excuse me... Mr. Jaczko, please go on.
The L.A. Times Reports:





Gregory Jaczko, head of the U.S. Nuclear Regulatory Commission, says the crisis is worse than Japanese officials appear to be letting on. 'This is a situation where people may be called in to sacrifice their lives,' he says of the crew working there.

"...people may be called in to sacrifice their lives"? This guy has never worked as a fireman or a cop or in the military, has he? Nope. Just a politician whose never had a real job in his life.

-- As the crisis continues to unfold at the Fukushima No. 1 (Daiichi) nuclear power plant, a growing disparity between Japanese and U.S. attitudes toward the problem is becoming apparent.

Whereas Japanese authorities have generally been restrained in their pronouncements about the risks, American officials are becoming increasingly vocal.



Yes. After the first two days of the Japanese government screwing things up with pronouncements  and then changing their story every two hours, they got smart and decided that, before they do make any announcements, they better have their facts straight and their act together. As opposed to the sensationalist western media that will print any old thing that fools like Gregory Jaczko "believe" or "believe may happen."

Japanese officials, for example, have consistently said the amount of radiation escaping from the damaged power plant remains relatively small. But on Wednesday, Gregory Jaczko, head of the U.S. Nuclear Regulatory Commission, said that he believes the spent fuel cooling pond atop reactor no. 4 at the facility about 150 miles north of 
Tokyo has boiled dry and that it is now spewing large amounts of radiation into the air.




Hell, I don't need to b-slap this guy here. I'll let the Associated Press do it. AP completely contradicts him:
A senior official with the U.N.'s nuclear safety agency said there had been "no significant worsening" at the Fukushima Dai-ichi nuclear plant but that the situation remained "very serious." Graham Andrew told reporters in Vienna that nuclear fuel rods in two reactors were only about half covered with water, and in a third they were also not completely submerged.


Low levels of radiation have been detected well beyond Tokyo, which is 140 miles (220 kilometers) south of the plant, but hazardous levels have been limited to the plant itself. Still, the crisis triggered by last week's earthquake and tsunami has forced thousands to evacuate and drained Tokyo's normally vibrant streets of life, its residents either leaving town or holing up in their homes. 


Thanks AP... What the...What a minute! Now AP gets into the act of sensationalism too (just couldn't control yourselves, could you?) You guys make it sound like Tokyo is a ghost town; "...forced thousands to evacuate and drained Tokyo's normally vibrant streets of life, its residents either leaving town or holing up in their homes"? Where do you guys get this stuff? Yes. Some people have left. But even the Japanese elementary schools are open in Tokyo and the stores are pretty well stocked up with most foods. Life goes on in Tokyo pretty much the same. 


Finally, now, we can see the reason for Mr. Jazcko's increasingly wild and sensationalist claims. He is catching flak and needs to cover his ass: 


Once again, the AP reports:


It could take days and "possibly weeks" to get the complex under control, U.S. Nuclear Regulatory Commission Chairman Gregory Jazcko said. He defended the U.S. decision to recommend a 50-mile evacuation zone for its citizens, a much stronger measure than Japan has taken.


Aha! Now we see the motivation for Mr. Jaczko to exaggerate and tell fibs. He is the one responsible for the US evacutating a 50 mile radius around the accident site. You can see that - from reading in between the lines - he is now taking criticism (deservedly so) for recommending a 50 mile evacuation zone. I'm sure there are other experts with much cooler heads who aren't panicking like the little girl Mr. Jaczko seems to be.


Japan's announced a few days ago that the evacuation zone would be 12 miles. Mr. Jaczko, on the other hand, should announce that he is evacuating his post immediately.

Finally, last but definitely not least, here is some great information from Professor Barry Brook. Brook is director of Climate Science at the University of Adelaide's Environment Institute. The UK Register reported.

Some of my favourite quotes:

"The situation with respect to the actual reactor cores at Fukushima
no longer appears to be causing huge concern."

"there is no sign of massive damage to the cores or release of
long-lived radioisotopes in significant quantities"

"The radiation near the reactors is mainly emitted by fast-decaying
isotopes in the steam which decay away within seconds or minutes of
being created. TEPCO admits that portions of fuel rod continue to be
uncovered at times, but residual heating levels in the fuel are now
hugely lower than they were in the days immediately after the quake
and the rods' heat-conducting alloy cladding helps transfer heat from
the exposed portions to the water."

"If someone can explain to me how those heavy particles, the heavy
metals and even the non-gaseous fission products can be carried over a
wide area, I'd like to hear it because I don't know a mechanism where
that could happen in these sort of reactors."

An especially enthusiastic thank you to Victor Vorski for this!
