When There Are Not Plans Ahead of Time

In Nuclear Industry on March 24, 2011 at 12:04 AM

Time after time the Japanese government and TEPCO are taking measures after the events and not before. This way they are risking unnecessary the lives of technicians, firefighters and Ground Self-Defense Forces.

A clear example was the cooling of the reactor number 3 early in the Saturday morning. The team planned initially to station a pumper close to the reactor and adjacent to the sea to draw seawater, and transfer the water to an elevating squirt truck through a hose.

But they found a problem: the seaside was (yet) covered with rubble making almost impossible that large-sized vehicles could to approach the site, so they have to relocate farther, and they have to put themselves at risk when they needed manually attach another hose to the original hose.

If TEPCO and the Japanese government had worrying about cleaning the zone from the first moment to allow quicker and safer operations, everybody had not got an extra radiation dose.

They have the ways. In fact, the GDSF sent two Type 74 tanks to help shift debris on Sunday. These tanks can be fitted with a blade like that of a bulldozer and the crew is protected of radiation by thick armor plating.

On Saturday, The firefighters were spraying water about 22 meters high from the ground with the squirt truck’s cannon. But there was a safer way, as there are German-made trucks with a 50 meter arm to pour water from a higher point. These trucks are not in Germany but in Mie Prefecture. Also, the construction company says this same type of machinery was used in Chernobyl.

They are sending now the trucks by request of the government, but I think it’s a bit late: in fact, they must be from the first day helping to cool the reactors.

By not thinking ahead the government and TEPCO are hampering the measures to fix the serious problems at Fukushima nuclear power plants, as radiation wasn’t enough problem.

The first voices are now claiming to bury the plant, and although it isn’t clear if the reactors are going to be dismantled or buried, I presume the government is not taking preemptive measures for this event. It is not easy to bury a nuclear reactor, because you need to reinforce the floors of the reactors and the operation takes time.

Will the Japanese government spend precious moments for not taking decisions ahead of time and again workers at the plant will get extra radiation for not being ready to the events?

Nuclear industry: see no danger, speak no danger, hear no danger

In Nuclear Industry on March 19, 2011 at 10:16 AM

Now we are on the verge of catastrophe as TEPCO is muttering that there is the possibility of bury the whole plant of Fukushima Daiichi with tons of sand.

They know that the company was never able to deal with this kind of disaster: too many human errors after the tsunami, insufficient backup equipment to take appropiate measures, no clear emergency plans…

The Tokyo Electric Power Company has been always a greedy company: they choose the boiling water nuclear reactors because were cheaper than other safer designs, they didn’t protect the auxiliary diesel generators inside closed buildings cause they estimated it was enough with the breakwater to stop a tsunami, and they have been following the events from behind because they knew the high economic cost of every extra measure to control the plant.

The worst is the nuclear industry in general keeps on the same way that TEPCO; like the ancient monkeys of Nikko they see no danger, speak no danger, hear no danger.

The first day of the accident they said that with light water reactors was impossible a meltdown cause this type of reactor stops the nuclear reaction by design (now we have 1 severe and 3 partial meltdowns), that in case of the worst the radioactivity would be low (nobody can approach some deathly places of Fukushima plant), that spent fuel pools take a week to deplete its water (2 pools now boiling and burning) and this moment they say there is no worry about fallout outside Japan (when 2 U.S. aircarriers had redeployed because radioactive clouds).

I am a supporter of nuclear energy, cause at this moment it’s the only viable way to western nations of get rid of the tirany of a few autocracies (enemies of our countries) to put a high extra cost to our hard work and daily lives and besides I don’t want my money goes to places where there is not democracy, but right now I think the nuclear industry must ponder if they are going to do things properly or they want to vanish in forthcoming years.

 

Finally, I put an official report and an independent report about the same nuclear accident. Test the differences.

GE Hitachi Updates! 3 out of 10 Requested Truck Mounted Turbines Ready For Shipment From Florida!

In Breaking News, Nuclear Industry on March 17, 2011 at 5:36 AM

NCNUKE – NC NUKE.COM – 16/03/2011 [LINK]

An excellent work by ncnuke giving a lot of information about GE and TEPCO working together for putting an end to this crisis.

Ten truck-mounted gas turbines are on the way from GE.

 

 

[EXTRACTS]

Responding to a request today from TEPCO to deliver 10 GE truck-mounted gas turbineswhich can provide temporary power […]. Three of those 10 are ready in Florida and are awaiting air transport.

 


Under any normal circumstances diesel generators are perfectly capable and the most cost efficient.  This leaves a very low inventory of these highly expensive specialty mobile gas turbines.  Even this limited supply of mobile gas turbines is seldom in use.  GE Hitachi appears to be willing to move mountains to get this vital technology to the disaster sight.


TEPCO’s shady history

TIM SHORROCK – TIMSHORROCK.COM – 14/03/2011 [LINK]

A dark view on TEPCO and Japanese nuclear industry.

 

 

[EXTRACTS]

If we’ve learned anything from the crisis so far, it’s that the Japan government and its nuclear industry don’t have the smoothest PR in the world. Ever since the tsunami knocked out the plant’s cooling system on Friday and the reactor cores began over-heating, the official word has been confusing, contradictory and downright mysterious.

 

 

TEPCO also has a history of obfuscation and falsification when it comes to safety.

 

 

[…] about the extent of breakdowns at Kashiwazaki-Kariwa, the world’s largest nuclear electricity-generating complex.” The paper continued:

The magnitude 6.8 quake 10 km offshore from the Honshu west coast plant caused subsidence of the main structure, ruptured water pipes, started a fire that took five hours to extinguish, and triggered small radioactive discharges into the atmosphere and sea.

Japan has had reactors shut and superficially damaged by earthquakes before, nuclear power stations have had safety failures before, and TEPCO management has been caught before covering up its plant problems. But this was the first time all three circumstances had coincided. This was the nearest thing Japan had seen to genpatsu-shinsai (a nuclear power station earthquake disaster).

 

 

In 2003, all 17 of its nuclear plants were shut down temporarily after a scandal over falsified safety-inspection reports. It ran into trouble again in 2006, when it emerged that coolant-water data at two plants had been falsified in the 1980s.

Is Tokyo Electric Power becoming Japan’s BP?

MARK GREGORY –  BBC – 16/03/2011 [LINK]

An interesting general analysis on TEPCO.

It’s easy to distrust a company that admitted to falsify 200 documents over 25 years.

 

 

[EXTRACTS]

Tepco is the largest power utility in Japan.

In normal times, it supplies about a third of the country’s electricity.

 


In 2002, the Japanese government accused Tepco of false reporting in routine inspections of nuclear facilities and of concealing information about safety lapses over many years.

 


Tepco eventually admitted to 200 occasions in which information had been falsified between 1977 and 2002. Further revelations of past concealment emerged five years later.


UN Calls Emergency Meeting as Japan Nuclear Crisis Deepens

In Breaking News, Nuclear Industry on March 17, 2011 at 3:16 AM

SHIGERU SATO & TSUYOSHI INAJIMA – BLOOMBERG – 16/03/2011 [LINK]

IAEA (UN’s nuclear agency) now is in big rush for an urgent meeting with Japanese authorities after a breech in number two reactor and other serious incidents at Fukushima.

Maybe too little, too late.

 

 

[EXTRACTS]

The United Nations’ nuclear agency will call an emergency meeting to discuss the crisis in Japan as a breach at the stricken Fukushima Dai-Ichi plant increased the risk of a radioactive leak.

IAEA Chief Yukiya Amano is flying to Tokyo to talk with authorities today and will return for the meeting as soon as possible, he told reporters in Vienna yesterday. It will be the first extraordinary meeting of the agency’s 35-member board since his election to succeed Mohamed ElBaradei two years ago.


Chernobyl clean-up expert slams Japan, IAEA

MICHAEL SHIELDS – REUTERS – 15/03/2011 [LINK]

A strong telling-off to Japanese nuclear industry over greed and safety procedures by nuclear accident specialist Iouli Andreev .

 

 

[EXTRACTS]

“The Japanese were very greedy and they used every square inch of the space. But when you have a dense placing of spent fuel in the basin you have a high possibility of fire if the water is removed from the basin,”
Andreev said.

 


Andreev said he understood all too well what the Japanese authorities in Fukushima were going through, and that creative solutions would be needed to contain the leaks.
