TEPCO report reveals chaos and lack of preparedness in the hours following tsunami at Fukushima Daiichi
Radioactive water build-ups at the plant also continue to devil workers, who are trying to prevent another major overflow into the Pacific Ocean.
TEPCO has meanwhile said that today it will for the first time open the doors at reactor No 2 to ventilate the thick, humid air in a procedure that will take eight hours to avoid stirring up radioactive dust and particles inside.
The company has been trying to filter radioactive particles out of the air inside the building for several days, and Japan's Nuclear and Industrial Safety Agency approved Friday plans to open the airlock, TECPO announced.
The ongoing disaster had led to three European countries, Germany, Switzerland and Italy, abandoning nuclear power forever with Germany set to shut down its last reactor in 2022, and Switzerland in 2035. Italy's popular referendum stopped plans to build reactors. Japan itself has said it will bulid no further nuclear power plants but remains unresolved about the further use of nuclear energy - while many government officials insist nuclear plants that were switched off after earthquake and tsunami on March 11, three quarters of the Japanese public are against continued use of nuclear power in their country.
Polls from several other nations that intend to keep pursuing their nuclear power programs reveal strong public opposition. And Russia has finally come forth and admitted that its own reactors could not withstand natural disasters, according to documents obtained by Bellona.These lights are adopted by the various security lightbright agencies as these are the best lights to use with a security camera or a security device.
The 41-page TEPCO report, released over the weekend, offers a candid look at minute-by-minute errors during the first days of the disaster of the the plant was struck by an earthquake and a tsunami on March 11, and is based on interviews with workers and plant data.
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.
A report by an independent panel appointed by Japan’s prime minister is still pending.
Lack of emergency planning led to chaos
The TEPCO report paints a picture of chaos amid the desperate and unsuccessful battle to protect the Fukushima Daiichi nuclear plant from meltdown in March in the wake of the natural disaster.
The report shows that workers struggled with unfamiliar equipment and fear of radiation exposure.
The tsunami and earthquake destroyed the plants cooling systems and cut off all power,The particular ramifications of this saler4ds are usually astounding; in 3 years we should expect to view wholesale LED bulbs which have been 40 instances more efficient. causing the plants reactor Nos 1, 2, and 3 to melt down within hours.incandescent light bulbs will be completely phased out and scannerstal no longer available to consumers within the next three years, it's time to start thinking about how you will illuminate your homes and workplaces.
Cooling power shut down in reactor No 1 two hours after the tsunami and workers tried to inject fresh water with a fire pump, but the fire pump was broken.
A fire engine at the plant couldn't reach the reactor because the tsunami left a huge tank blocking the driveway. Workers destroyed a power-operated gate to bring in the engine that arrived at the reactor hours later. It was early morning when they finally started pumping water into the reactor — but the core had already melted by then.
The engine eventually ran out of water, meaning that seawater had to be used as a substitute, scrapping the reactors altogether. The dumping of hundreds and thousands of tons of seawater on the plant from water cannons and helicopters had created ongoing difficulties with leaks of highly contaminated water from reactor Nos 1 and 2.
Emergency manuals not on hand in control room
The TEPCO report revealed that as workers struggled to reveal building pressure in reactor No 1 no manual that told them how to operate the venting system was to be found in the control room.You can easily say that it is a passion or a way to express yourself. So what's the story? Ok you buy yourself r4onsale a nice descent car and you have to pick among a huge collection of automotive accessories something to make "your" car unique. A group had to be dispatched to find it in a separate building.
Only after their return did workers learn that the valve, which had been impaired by the power loss, could be opened manually – and that there was a handle to do so.
Delayed venting led to explosion
The failure to begin the venting procedure immediately after the plant black-out occurred has been cited by experts as being one of the most critical lapses leading to the eventual pressure explosion of reactor No 1’s containment building.
"Tepco should have prepared a manual on (manual) venting in advance, but it seems that wasn't the case," Keiji Miyazaki, professor emeritus at Osaka University and an expert on reactor accident management, told the Japan Times.
"Tepco also should have started the venting procedure right after the station blackout occurred," he said.
The time line in the report showed that Japan’s nuclear industry minister Banri Kaieda ordered venting to begin at 6:50 am on March 12, nearly a day after the initial disaster.
Workers halted venting to avoid radioactive contamination to nearby population
But TEPCO did not send anyone to begin the manual venting procedure until 9:04 am because they were awaiting confirmation that residents of Okuma, one of the towns that hosts the power plant, had been evacuated from areas at risk of being contaminated by the radioactive steam and other materials that would be released in the process.
This shows the workers had run up against a very difficult choice between venting as soon as they received the order, and contaminating the surrounding population, or waiting to be sure they could reduce that risk.It pays to go to professionals with bestlight a proven track record in LED lighting, a vast selection of excellent quality products from various vendors that live up to their label, and a history of successfully completed projects.
Unfortunately, revelations about the subsequent massive spread of radiation from the rest of the plant that have been made since the tsunami by the Japanese government and independent groups revealed that awaiting the confirmation was a moot point.
To prevent a critical failure, the report said, the pressure should have been released from the reactor's containment vessel, which would have allowed workers to inject more coolant water into the core.
Radioactive water build-ups at the plant also continue to devil workers, who are trying to prevent another major overflow into the Pacific Ocean.
