New report shows early chaos at Japan nuke plant

By MARI YAMAGUCHI
updated 6/19/2011 10:53:42 AM ET

TOKYO — A new report says Japan's tsunami-ravaged nuclear plant was so unprepared for the disaster that workers had to bring protective gear and an emergency manual from distant buildings and borrow equipment from a contractor.

The report, released Saturday by plant operator Tokyo Electric Power Co., is based on interviews of workers and plant data. It portrays chaos amid the desperate and ultimately unsuccessful battle to protect the Fukushima Dai-ichi nuclear plant from meltdown, and shows that workers struggled with unfamiliar equipment and fear of radiation exposure.

TEPCO has been criticized for dragging its feet on venting and sea water cooling — the two crucial steps that experts say could have mitigated the damage. Company officials have said the tsunami created obstacles that were impossible to anticipate. An investigation by an independent panel is pending.

The report revealed insufficient preparations at the plant that TEPCO hadn't previously acknowledged. It said plant workers had a disaster drill just a week before the tsunami and "everyone was familiar with emergency exits," but it apparently did not help them cope with the crisis.

1. And TEPCO represents some of the very best the nuclear industry has to offer.
For a couple of decades now Japan's nuclear program has been considered a benchmark by which to judge the proficiency and professionalism of nuclear power plant operators.

2. Japan has the 2nd worst nuclear safety record in the world.
Japan's nuclear industry has been roundly criticized for years before this accident occurred. Long before the Fukashima accident, other events such as the Tokaimura nuclear accident, the Mihama steam explosion, and the cover-up of an incident at the Monju reactor resulted in many questioning Japan's commitment to safety at it nuclear plants. There have been a total of nine nuclear accidents in Japan over the last 15 years, some resulting in fatalities. Even if you adjust the data for the number of reactors (Japan has a lot compared to other countries), that makes their record the second worst in the world, ironically only better than the US. A complete list is here:

It is not surprising that you didn't offer up a link to support your claim, given that it is a complete fabrication.

3. ROFLMAO You mean this is supposed to support your attempt at scapegoating?
From your link:

The nuclear industry says that new technology and oversight have made nuclear plants much safer, but 57 accidents have occurred since the Chernobyl disaster in 1986. Two thirds of these mishaps occurred in the US.<1> The French Atomic Energy Agency (CEA) has concluded that technical innovation cannot eliminate the risk of human errors in nuclear plant operation. An interdisciplinary team from MIT have estimated that given the expected growth of nuclear power from 2005 – 2055, at least four serious nuclear power accidents would be expected in that period.


Nuclear power accidents in Japan

2 Nov 1978 Fukushima No1, Japan Japan's first criticality accident at No 3 reactor, this accident was hidden for 29 years and reported on 22 Mar 2007

1981 Tsuruga, Japan Almost 300 workers were exposed to excessive levels of radiation after a fuel rod ruptured during repairs at the Tsuruga Nuclear Power Plant.<9>

December 1995 Tsuruga, Japan The fast breeder Monju Nuclear Power Plant sodium leak.<9> State-run operator Donen was found to have concealed videotape footage that showed extensive damage to the reactor.<10>

March 1997 Tokaimura, Japan The Tokaimura nuclear reprocessing plant fire and explosion. 37 workers were exposed to low doses of radiation. Donen later acknowledged it had initially suppressed information about the fire.<9><10>

18 Jun 1999 Shiga, Japan A fuel loading system malfunctioned and set off an uncontrolled nuclear reaction and explosion.<9>

September 1999 Tokaimura, Japan The criticality accident at the Tokai fuel fabrication facility.<9> Hundreds of people were exposed to radiation and two workers later died.<10> 2

2002 Onagawa, Japan Two workers were exposed to a small amount of radiation and suffered minor burns during a fire.<10>

9 Aug 2004 Mihama, Japan A steam explosion at the Mihama-3 station; the subsequent investigation revealed a serious lack in systematic inspection in Japanese nuclear plants, which led to a massive inspection program.<11> 5

2006 Fukushima No1, Japan A small amount of radioactive steam was released at the Fukushima Dai-ichi plant and it escaped the compound.<10>

16 Jul 2007 Kashiwazaki, Japan a severe earthquake (measuring 6.8 on the Richter scale) hit the region where Tokyo Electric's Kashiwazaki-Kariwa Nuclear Power Plant is located and radioactive water spilled into the Sea of Japan; as of March 2009, all of the reactors remain shut down for damage verification and repairs; the plant with seven units was the largest single nuclear power station in the world.<11>

December 2009 Hamaoka, Japan Leakage accident of Radio active water. 34 workers were exposed to radiation

11 Mar 2011 Fukushima No1, Japan The world's second INES 7 accident. A magnitude 9.0 earthquake and associated tsunami triggered cooling problems at Fukushima 1 & 2 stations with several reactors. Hydrogen explosions cause structural damage, and loss of coolant results in meltdowns in three units and a fire in overheated spent fuel rods. Radioactive steam was released into the atmosphere, and highly radioactive water spilled into the ocean through utility trenches. Some immediate injuries resulted.

18 Mar 2011 Fukushima No2, Japan Japanese Nuclear and Industrial Safety Agency reported that the condition of reactors #1, #2 and #4 of Fukushima Dai 2 Plant is equivalent to INES level 3.

But I'm sure you can actually point to examples where in the preFukushima era "Japan's nuclear industry has been roundly criticized for years" by the same the nuclear supporters on DUEE, like yourself, that are now trying to scapegoat them as they did the Russians with Chernobyl. While you're thinking of where you can find that nonexistent text, let's take another look at the opening paragraph of the wikilink you offered:

"The nuclear industry says that new technology and oversight have made nuclear plants much safer, but 57 accidents have occurred since the Chernobyl disaster in 1986. Two thirds of these mishaps occurred in the US.

The French Atomic Energy Agency (CEA) has concluded that technical innovation cannot eliminate the risk of human errors in nuclear plant operation.

An interdisciplinary team from MIT have estimated that given the expected growth of nuclear power from 2005 – 2055, at least four serious nuclear power accidents would be expected in that period.

4. You're funny Kristopher
Edited on Sun Jun-19-11 09:45 PM by Nederland
First you claim that Japan is a model of nuclear safety, then when someone calls you out on the outright lie you change the subject. Did you think no one would notice?

And what's up with highlighting the fact that two third of the accidents occurred in the US? Do you think you are proving something here, or perhaps you didn't even read my post in which I said: "...that makes their record the second worst in the world, ironically only better than the US.

Admit the truth Kristopher, you don't actual read what anyone else says around here, do you? It's all just knee jerk reactions...

5. How is that changing the subject?
I think that the gap between the Japanese and the Americans reflects what I said - when the Japanese are pointed to, in projects like South Texas or Comanche Peak, they are touted as THE partners with world class expertise; and the thing is, they are!!! And that is what makes awareness of their performance such a damning indictment of the nuclear industry as a whole. Over the past three months a recurring theme popping up in public discussions is "if it can happen in Japan, it can happen anywhere."

You felt that the accident reports were a measure of the reputation for competence of the nuclear industry and cited Japan as "the second worst". I just reflected the information you provided without further interpretation. Now you think the information YOU put forth is somehow changing the topic. I don't think that interpretation makes me "funny", but it does make you seem a bit weird.

6. The subject is the safety record of the Japanese nuclear program
You claimed that "Japan's nuclear program has been considered a benchmark by which to judge the proficiency and professionalism of nuclear power plant operators". You stated that claim in your first post on this thread with absolutely no proof, and you still have provided no proof that it is true. You have provided no proof because there is none. Any discussion of anything other than whether or not Japan's program is "considered a benchmark" is changing the subject.

If you simply admit that your original assertion was incorrect I'd be happy to discuss something else, but until you prove that you are capable of admitting you are wrong about something there is little point.

7. But you've contradicted it with "absolutely no proof".
Edited on Sun Jun-19-11 10:53 PM by kristopher
Your citation certainly wasn't anything that discusses perception related to the proficiency or professionalism of Japan's nuclear program.

And seriously, do you honestly think that a demand from you for proof of that kind of statement requires from me anything other than to tell you to piss off?

I think it is true; now if you don't agree, you are welcome to present PRE-Fukushima evidence showing that Japan was, in fact, held up by their circle of peers as anything OTHER THAN a world leader or something to emulate in terms of safety, proficiency and professionalism.

10. AP study: U.S. nuclear regulators weaken safety rules
AP study: U.S. nuclear regulators weaken safety rules

LACEY TOWNSHIP, N.J. —

Federal regulators have been working closely with the nuclear power industry to keep the nation's aging reactors operating within safety standards by repeatedly weakening those standards, or simply failing to enforce them, an investigation by The Associated Press has found.

Time after time, officials at the U.S. Nuclear Regulatory Commission have decided that original regulations were too strict, arguing that safety margins could be eased without peril, according to records and interviews.

The result? Rising fears that these accommodations by the NRC are significantly undermining safety - and inching the reactors closer to an accident that could harm the public and jeopardize the future of nuclear power in the United States.

Examples abound. When valves leaked, more leakage was allowed - up to 20 times the original limit. When rampant cracking caused radioactive leaks from steam generator tubing, an easier test of the tubes was devised, so plants could meet standards.

Failed cables. Busted seals. Broken nozzles, clogged screens, cracked concrete, dented containers, corroded metals and rusty underground pipes - all of these and thousands of other problems linked to aging were uncovered in the AP's yearlong investigation. And all of them could escalate dangers in the event of an accident.

Yet despite the many problems linked to aging...

12. Fukushima report shows nuclear power can never be safe and cheap
http://www.democraticunderground.com/discuss/duboard.php?az=view_all&address=115x300603#300603

(Guardian) Fukushima report shows nuclear power can never be safe and cheap

The first "independent" review of the Fukushima nuclear disaster was published today and it does not make reassuring reading.

Japan is perhaps the most technologically advanced nation on Earth and yet, time after time, the report finds missing measures that I would have expected to already be in place. It highlights the fundamental inability for anyone to anticipate all future events and so deeply undermines the claims of the nuclear industry and its supporters that this time, with the new generation of reactors, things will be different.

I used quote marks on the word "independent" because the report comes from the International Atomic Energy Association (pdf) (IAEA) which, while independent of Japan, is far from independent from the nuclear industry it was founded to promote. But this conflict of interest only makes the findings of the IEAE's experts more startling.

So let's take a look at some of the 15 conclusions and 16 lessons (I've edited a bit for brevity).
There were insufficient defence-in-depth provisions for tsunami hazards. In particular, although tsunami hazards were considered 2002, the tsunami hazard was underestimated. Moreover, those additional protective measures were not reviewed and approved by the regulatory authority. Severe accident management provisions were not adequate to cope with multiple plant failures.

So, they looked at the...
