Global help urged to avert reactor 4 pool fire

Source: Japan Times

The risk of a fire starting in reactor 4's spent-fuel pool at the Fukushima No. 1 plant continues to alarm scientists and government officials around the world, prompting a leading U.S. nuclear expert to urge Japan to tap global expertise to avert a catastrophe.

Arnie Gundersen, a nuclear engineer and former executive in the nuclear power industry who is now one of its foremost critics in the United States, has been monitoring the No. 1 plant since the March 2011 triple meltdowns through his Vermont-based Fairewinds Energy Education nonprofit organization.

During a trip to Japan in late August and early September, Gundersen met with Diet members, lawyers and citizens' groups to discuss conditions at the wrecked power station and told an audience in Kyoto on Monday that fears over the spent-fuel pool in reactor 4 remain high.

"The spent-nuclear-fuel pool at Fukushima No. 1's unit 4 remains a sleeping dragon. The situation and possibility of a fuel pool fire in reactor 4 in the days (immediately) after the (March 2011) quake was the reason the U.S. government recommended that the evacuation zone be (set at) 80 km," said Gundersen, who served as an expert witness during the federal investigation into the 1979 Three Mile Island disaster in Pennsylvania.

1. Some background info, because it always comes up:

Last edited Sat Sep 8, 2012, 08:29 AM USA/ET - Edit history (1)

Some background info, because it always comes up:

Arnie Gundersen is a nuclear engineer who blew the whistle on safety issues back in the 1990's resulting in a $1.5 million lawsuit and congressional hearings. Since then the nuclear industry and its shills have unsuccessfully tried all kinds of sleazy tactics at discrediting him. They've even falsely claimed he's not a nuclear engineer - it's the same kind of "fair game" tactics right-wingers unsuccessfully used trying to discredit Valerie Plame, claiming she was just a glorified secretary, etc. Please don't fall for that nonsense. He has a Masters Degree in Nuclear Engineering, was a senior vice president of Nuclear Energy Services, after being blacklisted by the nuclear industry he taught math and became an independent consultant on nuclear energy. He isn't "anti-nuclear", he just debunks a lot of the PR and happy talk from the nuclear industry.

In 1993 NRC Chairman Ivan Selin testified in response to a question by Committee Chairman Senator John Glenn:
Everything Mr. Gundersen said was absolutely right; he performed quite a service

http://www.archive.org/details/federalregulatio00unit


In 2007 the Vermont Daily wrote:
What Arnie Gundersen Says About Yankee Eventually Becomes Truth About Yankee
by Philip Baruth

<snip>

Arnie was an executive in the nuclear industry, back in the late ’80’s, but in 1990 he came forward as a whistleblower and was fired the same year. Over the next several years, his case got a great deal of attention, and he testified before Congress during hearings on ways to protect whistleblowers.

Fast-forward to 2007. Arnie is now a prominent nuclear safety expert witness. And he’s also a longtime reader of this site.

<snip>

The fact that Arnie’s very specific projections so closely mirror eventual reality at the plant says several things to me:

1) Arnie Gundersen knows from whence he speaks. He is not some crank with an irrational fear of nuclear energy. Rather, he is a highly skilled watchdog, whose views the State should begin actively soliciting rather than fighting or disparaging.

In 1995 the New York Times wrote about his fight with the nuclear industry:
Paying The Price For Blowing The Whistle

By Julie Miller
Published: February 12, 1995

FOR three years, Arnold Gundersen was awakened by harassing phone calls in the middle of the night. He became so concerned about his family's safety that he bought a large dog for protection. The problem? He was a whistle-blower, one of those who take on the dismally unpopular role of exposing what they find to be unsafe or unlawful practices in the workplace, especially the nuclear workplace.

<snip>

Mr. Gundersen, who lives in Warren, told of the day in 1990 when he discovered radioactive material in an accounting safe at Nuclear Energy Services in Danbury, the consulting firm where he held a $120,000-a-year job as senior vice president. Three weeks after he notified the company president of what he believed to be radiation safety violations, Mr. Gundersen said, he was fired.

He is fighting a $1.5 million lawsuit filed against him by his former employer for continuing to discuss the alleged safety violations publicly after agreeing to an out-of-court settlement. Mr. Gundersen said he believes he was blacklisted, citing an April 22, 1991, letter concerning him that the company sent to 78 people. He also says he was harassed and fired for doing what he thought was right.

Mr. Gundersen's case, according to a number of whistle-blowers and others interviewed, is not uncommon, especially in the nuclear industry. Even though nuclear workers are encouraged to report potential safety hazards, those who decide to do so say that they risk demotion and dismissal. Instead of correcting the problems, whistle-blowers and their supporters say, industry management and government forces attack them as the cause of the problem.

Unnecessary for me, as I have been listening to his briefings from the beginning and well, while I'm not a nuclear scientist, I'm pretty smart and can suss out bullshit pretty well. Gundersen has great credibility with me.

5. More from the article:

But even today, concerns persist among experts worldwide that reactor 4's pool is still at risk of boiling dry. If this were to occur, it would necessitate a massive and immediate evacuation of the surrounding area.

Nuclear fuel rods are extremely thin and clad with zircaloy, a zirconium alloy that contains a tiny amount of tin and other metals. But zircaloy burns if it is exposed to air, as shown in a test conducted at the Sandia National Laboratory in New Mexico just two weeks before the Great East Japan Earthquake devastated the Tohoku region.

"I told Tepco that while I realized they hoped and believed that there will always be water in the nuclear fuel pool, I had to ask whether or not they had (already prepared and stationed) any chemicals to put out a nuclear fuel pool fire in the event they were wrong.
"Tepco's response was that there was nothing in the fuel pool that could burn, a statement I find appalling."

24. Pure Zirconium, like Uranium will spontaneously combust when exposed to Oxygen.

But that point is irrelevent, since it then forms an oxide layer which mitigates the effect. Aluminum does the same thing. The Uranium in the core is actually a blend of Uranium Oxide and Zirconium Oxide. As it has already been oxidized it won't burn. Zircalloy is the same, we had a pallet of them stacked on the aircraft carrier next to my boat that I actually saw. They weren't on fire. If they catch fire it will be due to an imbalance of thermal energy not because of the metallurgical properties of zirconium.

14. More info on the latest from Fukushima ( has anyone seen my reactor fuel cores?)

from this article:
http://www.platts.com/RSSFeedDetailedNews/RSSFeed/ElectricPower/7048069

Key details of how the accident at Japan's Fukushima I nuclear plant played out have yet to be determined and may not be known for five years or more, when important parts of the plant are safer to enter, officials with the Japanese and US nuclear industries told a US National Academies review committee Thursday.

A Japanese civil engineering society had discounted the possibility of a large earthquake and tsunami off the coast of Fukushima prefecture because of a lack of evidence of such events since the 17th century, Tepco manager Shin Takizawa said. A study in 2002 that suggested such an earthquake was possible and historical reports of a large tsunami in the area in the ninth century were under review at the time of the 2011 earthquake, but had not been confirmed, he said.
"In hindsight, if we were able to return to 2002 ... we would have taken different actions," Takizawa said.

Yasunori Yamanaka, manager of Tepco's nuclear safety engineering group, said following the meeting that one of the key pieces of information that will be learned in the coming years is the location and condition of the core of nuclear fuel in the three reactors that experienced meltdowns. Tepco believes the uranium fuel of unit 1 at Fukushima I almost entirely melted its way through the bottom of the thick steel reactor vessel and poured to the floor of the containment structure, eating through a portion of the concrete floor of that area.

The company plans to use cameras and other surveillance equipment to determine how much of the core of units 2 and 3 remain in the reactor, Yamanaka said. The company believes almost half of the fuel in those units, which maintained core cooling longer, melted, he said. It may take more than five years before Tepco can determine whether the fuel in those units remains in the bottom of the reactor vessel or also fell to the containment floor, Yamanaka said.

16. Why do I have feeling TEPCO will not even be around in 5 years?

Surely massive lawsuits will be filed for years against it.

TEPCO could always pull a Blackwater....go "out of business" or sell itself, then emerge as a "new" oompany under a new name.

If an earthquake topples reactor 4..all bets are off.

20. THIS FUKISHIMA REACTOR 4 SITUATION IS ABOUT AS FUNNY AS

CANCER AND DEATH. Sorry, folks, but this ain't nothin' to be a'laughin' at, we as a global community, need to STOP THIS INSANITY. A nuclear fire could happen where the more than 100 tons of fuel rods would burn and burn until burnt up would endanger every life on this beautiful planet. Those who didn't die, would have horrible diseases and would probably envy the dead...No it ain't laugh time, it's time for ACTION. Please do all you can right now.
