After failures, TEPCO to use special cement to prevent contaminated water leaks

AJ201411220030M

November 22, 2014

The operator of the crippled Fukushima nuclear plant plans to fill in trenches on the coastline in yet another attempt to prevent highly contaminated water from pouring into the sea.

Under the plan, approved by the Nuclear Regulation Authority on Nov. 21, Tokyo Electric Power Co. will inject a special cement mixture into the seaside trenches of the No. 2 and No. 3 reactors while pumping up radioactive water accumulating in them.

The special mixture does not absorb water so it can spread more easily along the bottom of the trenches, displacing the tainted water.

The new method will allow radioactive materials to remain in the surrounding soil, but TEPCO decided to employ the technique because it puts high priority on preventing massive amounts of highly contaminated water from leaking into the ocean.

This spring, TEPCO tried to stop the water influx at the trench for the No. 2 reactor by freezing the junction of the turbine building and the trench, but the operation was tough-going.

The company then attempted to stop the water inflow with a cement mixture, but was unable to do so completely.

TEPCO gives up on freezing tainted water

Nov. 21, 2014
The operator of the Fukushima Daiichi nuclear plant is drastically changing its plan to remove highly radioactive water from underground tunnels at the facility.

The tunnels have been inundated with water from the plant’s heavily contaminated reactor buildings.

Tokyo Electric Power Company, or TEPCO, this year began work to freeze water at the ends of the tunnels to block the inflow. The firm finished the work early this month.

But TEPCO officials found that water levels in the tunnels were still changing in sync with volumes in the reactor buildings.

The officials admitted to the Nuclear Regulation Authority on Friday that the tunnels hadn’t been plugged.

They said they’re giving up on the plan, and proposed pouring cement into the flooded tunnels while removing water from them. They said they want this done from late November.

The authority’s commissioners asked whether the new method can really halt the inflow. They also spoke of the risk of cracks forming in cement.

The authority approved TEPCO’s plan in the end, on condition that the procedure be halted in late December to see whether it’s working.

Commenting on the change, one commissioner asked what all the trouble over the past months was for.

Tepco fails to halt toxic water inflow at Fukushima No. 1 trenches

Nov 22, 2014

Tokyo Electric Power Co. admitted failure Friday in its bid to halt the flow of toxic water into underground tunnels alongside the ocean at the Fukushima No. 1 plant and said that it will try using a specially developed cement instead.

Some 11,000 tons of highly radioactive water have accumulated in the tunnels, trenches dug to house pipes and cables that are connected to the reactor 2 and 3 turbine buildings of the wrecked facility, according to Tepco.

There are fears that this toxic buildup, which is being caused by the jury-rigged cooling system and groundwater seepage in the reactor basements, could pour into the Pacific, which is already being polluted by other radioactive leaks. Groundwater is entering the complex at 400 tons a day.

Extracting the toxic water is a critical step in Tepco’s plan to build a huge underground ice wall around the four destroyed reactors to keep groundwater out.

Initially, Tepco sought to freeze the water in a section of tunnel connected to the No. 2 reactor building. This was intended to stop the inflow and allow the accumulated water to be pumped out. The utility said it took additional measures that also failed.

On Friday, Tepco proposed a new technique for the tunnels: injection of a cement filler especially developed for the task while pumping out as much of the accumulated water as possible.

Under the new method, however, it would be difficult to drain all of this water and some of it would be left behind, endangering plant workers, Tepco acknowledged.

Nevertheless, a Nuclear Regulation Authority panel of experts green-lighted the new strategy at a recent meeting. Some of the experts argued that Tepco should stick to the original plan and draw out all of the water. Others said giving up on it may hamper the construction of the ice wall.

Japan’s very problematic law on removing nuclear waste for Fukushima Prefecture

Diet passes legislation to remove nuclear waste from Fukushima in 30 years http://ajw.asahi.com/article/0311disaster/fukushima/AJ201411200041 November 20, 2014 THE ASAHI SHIMBUN

wastes-Fukushima-for-incineThe Diet passed a bill Nov. 19 mandating that radioactive soil and debris from the Fukushima decontamination work be moved outside the prefecture within 30 years, a step toward building interim storage facilities for the waste.

The law amendment was one of the five conditions set in September when the Fukushima prefectural government agreed to accept interim facilities to store contaminated waste collected during cleanup efforts around the crippled Fukushima No. 1 nuclear power plant.

Environment Minister Yoshio Mochizuki praised the legislation as a “major step forward.” However, hurdles remain high for the interim facilities–planned in Okuma and Futaba near the nuclear plant–to start accepting the waste in January as scheduled.

The bill amends a law regulating operations of the government-affiliated Japan Environmental Safety Corp. (JESCO), which is commissioned to dispose of used polychlorinated biphenyl (PCB).

The revised law stipulates the government will take necessary measures to remove waste from the prefecture for final disposal within 30 years after the interim facilities start operations. It also holds the government responsible for running the interim waste storage facilities and commissions JESCO to operate them.

Among the other conditions set by Fukushima Prefecture, the central government has agreed to earmark construction-related subsidies in its budget and take charge of the operation and maintenance of traffic routes for carrying in the waste.

One big problem for the government, however, is purchasing land for the facilities. The planned construction zone stretches 16 square kilometers, comprising 2,365 land plots belonging to individual owners.

As of the end of September, the government has located the whereabouts of only 1,269 landowners, partly because they live outside their properties as evacuees.

The government first plans to create temporary storage sites on individual land plots it purchases to start accepting radioactive waste there as early as possible. But it has not reached a purchase or lease agreement with a single landowner.

Taking into account this stumbling block, reconstruction minister Wataru Takeshita said Nov. 7 that the government’s plan to open the interim storage facilities in January will likely be pushed back.

Radioactive slurry at Fukushima nuclear reactors would be a huge hazard, if it leaked out

Fukushima Daiichi Updates From IRID Part 3; Testing The Goo Simply Info, November 19th, 2014 (Good diagrams) 

IRID has made some progress on their research to find ways to seal the containment structures at Fukushima Daiichi. The plan has been to flood the containment structures in order to provide shielding during the fuel removal procedures. Concern has been raised about the ability of these structures to hold the weight and pressure of that much water or how this would impact the structure during an earthquake. The structures are already severely damaged along with the many locations where they leak.

The current research effort is looking for ways to try to seal the leaks in each of the areas known to be a leak path for the containment structure. One aspect that has not been discussed is what would happen if these structures did have a failure and leak after flooding. It is known that the reactor containment structures contain some loose fragmented fuel and other highly radioactive debris. A major leak could let loose a considerable radioactive slurry that would need to be quickly contained and remediated………http://www.fukuleaks.org/web/?p=14136

Earthquake fault under Tsuruga nuclear reactor is active – say’s Japan’s Nuclear Regulator

nuke-earthquakeflag-japanNuclear watchdog panel: Fault under Tsuruga reactor is active  THE ASAHI SHIMBUN, 20 Nov 14 

A fault line beneath the No. 2 reactor of the Tsuruga nuclear power plant is indeed active, an expert panel of the Nuclear Regulation Authority concluded Nov. 19, drawing criticism from the plant’s operator.

Japan Atomic Power Co. vowed to challenge the panel’s conclusion, which, if it stands, would force the company to decommission the reactor under new safety rules……..

The NRA’s assessment of the fault last year came when Kunihiko Shimazaki, a seismologist known for his tough attitude toward power companies, was a deputy chairman of the watchdog. Utilities and ruling coalition officials criticized Shimazaki over his “hurried conclusion” on the Tsuruga plant.

Although Shimazaki’s term ended in September and he was replaced, the NRA’s position on the fault was not overturned.

The fault line survey at the Tsuruga plant was originally started at the request of the now-dissolved Nuclear and Industrial Safety Agency.

Fault inspections are a separate process from the safety screenings required to restart reactors, so Japan Atomic Power can still submit an application to resume operations at the reactor.

However, NRA Chairman Shunichi Tanaka has said he would respect the expert panel’s conclusion when deciding whether to allow reactors to restart.

Radioactive water keeps entering Fukushima Daiichi tunnels while water is pumped out

water-radiationRadioactive water to tunnels unlikely stopped http://www3.nhk.or.jp/nhkworld/english/news/20141118_03.html Nov. 17, 2014 The officials overseeing the decommissioning of the Fukushima Daiichi nuclear power plant say a barrier designed to prevent radioactive water from entering underground tunnels is likely not doing its job.

The decommissioning work includes a plan to remove highly-radioactive water from tunnels under the facility grounds and then fill them with concrete to prevent leaks to surrounding soil.

A barrier to hold out water during this process was under construction until November 6th.
On Monday, workers removed 200,000 liters of water, estimating that water levels in the tunnels would drop by 80 centimeters.
However, the levels went down by only 20 centimeters. This led officials to conclude that more water was likely entering the tunnels from the reactor building while water was being pumped out.

The officials considered the effects of radioactive water on ground water, and decided on a plan to fill tunnels in with cement before they are completely drained.

They say the operation will require carefully handling to prevent any overflow of contaminated water.

Japan’s Prime Minister Abe is banking on getting a new voter mandate

Abe is banking on getting a new voter mandate BY REIJI YOSHIDA, JAPAN TIMES 18 NOV 14 “…….Abe would never admit in public what is widely believed to be the real reason for the snap election: A campaign as early as next month will likely strengthen the ruling camp and Abe himself.

Tepco unable to halt tainted water flowing into tunnels at Fukushima

Nov 18, 2014

Tokyo Electric Power Co. appears unable to stem the flow of radioactive water from the No. 2 reactor building to underground tunnels at the Fukushima No. 1 power plant, officials said.

Tepco has injected cement into the joints that connect the tunnels, which are used to run cables, and the building to halt the flow of contaminated water and remove accumulations from the tunnels.

But water levels suggest the effort has remained unsuccessful so far, the officials said. The company began the cement injections after failing to create an “ice wall” over the summer by freezing water inside the joints that would have blocked the flows.

After the cement injections, Tepco pumped 200 tons of tainted water out of the tunnels Monday, causing levels inside to fall around 20 cm, the officials said.

However, if the joints were completely sealed, water levels would have fallen roughly 80 cm, the officials said, indicating the possibility that contaminated water is still flowing into the tunnels.

The officials also noted the possibility that groundwater may be flowing into the tunnels. However, recent data has shown that the amount of radioactive materials in the tunnel water was very high, an official in the Nuclear Regulation Authority said.

“Concentrations should have been lower if large amounts of groundwater are really flowing in,” the official noted.

If the cement injections end in failure, too, Tepco plans to remove radioactive water while injecting cement into the tunnel — an operation that could put plant workers at greater risk of radiation exposure.

The tunnels are believed to contain some 5,000 tons of tainted water. Some observers believe the water may be leaking into the ground and reaching the Pacific.

Op-Ed: Fukushima disaster — Ignorance is bliss despite the dangers

103488f67f75a04b2da4c7277efe95d5d0bcf3b8_1The Sendai nuclear power plant will become the first of Japan’s 48 commercial reactors to be restarted after they were all shut down since the Fukushima disaster in 2011

By Karen Graham     November 18, 2014

Little is reported in the media about the clean up after the Fukushima Power Plant disaster. After three years of cover-ups and misleading information, released to quell public fears, there is still reason to be wary. The danger is still very real.

The Fukushima Daiichi nuclear power plant disaster in 2011 is still impacting lives today. Over 120,000 people from the area are living in a nuclear limbo, according to the guardian. Once close-knit families are now forced to live apart in temporary housing complexes, many of the homes hastily thrown up in an effort to get people out of radiation “hot-spots.”

Japan’s population has been inundated with half-truths and sometimes, outright lies, concerning the progress being made in the clean-up efforts in Fukushima. For the thousands of workers tasked with the laborious details of doing the actual work, just knowing their efforts are inadequate must be mind-numbing.

Fukushima Daiichi’s manager, Akira Ono is the man in charge of the clean up efforts, and he admitted to the Guardian that there is little cause for optimism. No matter what the workers do, there is still a huge problem with contaminated water. Over 400 tons of groundwater flow every day from the hills outside the plant and into the basements where the three stricken reactors are located.

There, the water mixes with the coolant water being pumped in to keep the melted fuel from overheating and causing another nuclear accident. TEPCO says “most of the water” is pumped out into holding tanks, but ever-increasing amounts end up seeping into maintenance trenches, and then into the ocean. This has to be depressing for Ono and the men and women walking into the facility every day.

While Americans have been sitting back and ignoring the ongoing disaster that is Fukushima, other countries have taken notice. Germany and Italy are looking at the viability of continuing to depend on nuclear power, and are opting instead for other more eco-friendly sources. And surprisingly, the news media in other countries is also paying attention to what has been going on at the Fukushima power plant.

Arnold Gunderson, a former high-level nuclear industry executive, was cited in an article written in Al-Jazeera English, entitled “Fukushima: It’s much worse than you think,” in June, 2011. In the story, Gunderson is quoted as saying, the Fukushima disaster was “the biggest industrial catastrophe in the history of mankind. Twenty nuclear cores have been exposed at Fukushima.” Gunderson also points out that the site’s many spent-fuel pools give Fukushima 20 times the radiation release potential of Chernobyl.

If people on the North American coast think they are safe from the effects of radiation from the Fukushima disaster, not only are they dreaming, but they are going to be in for a rude awakening. Yes, there were a few stories telling us the radiation levels reaching our west coast were “tiny amounts,” But how many additional infants are going to die, and how many more people, children and adults are going to end up with unexplained cancers before someone wakes up to what is happening?

And the American public needs to wake up right now. We have nuclear disasters just waiting to happen in our own back yard. From the Diable Canyon power plant in California, to the Cooper Nuclear Station near Brownville, Nebraska that was almost inundated with floodwaters in June, 2014, the list is getting longer and longer. The Nuclear Regulatory Committee has been forced to ease up on some regulations or just ignore them when it comes to helping power plants in the U.S. to meet what officials call “unnecessarily conservative” standards. Yes, ignorance is bliss. That is scary, folks,

Contaminated water swamps Fukushima No. 1 cleanup

n-tepco-a-20141117-870x597The Advanced Liquid Processing System of the Fukushima No. 1 plant is seen Wednesday

Nov 16, 2014

More than three years into the massive cleanup of the Fukushima No. 1 power plant, only a tiny fraction of the workers are focused on key tasks such as preparing for the dismantling of the wrecked reactors and removing radioactive fuel rods.

Instead, nearly all the workers at Fukushima No. 1 are devoted to a single, enormously distracting problem: coping with the vast amount of contaminated water, a mixture of groundwater running into recycled water that becomes contaminated and leaks after being pumped into the reactors to keep their melted cores from overheating.

A number of buildings housing water treatment machines and hundreds of huge blue and gray industrial storage tanks to store the excess water are rapidly taking over the grounds at the plant, which saw three of its six reactor cores suffer meltdowns from the 3/11 quake and tsunami. Workers were still building more tanks during a visit to the complex Wednesday by a group of foreign media.

“The contaminated water is a most pressing issue that we must tackle. There is no doubt about that,” said Akira Ono, head of the plant. “Our effort to mitigate the problem is at its peak now. Though I cannot say exactly when, I hope things start getting better when the measures start taking effect.”

The numbers tell the story:

6,000 workers

Every day, about 6,000 workers pass through the guarded gate of Fukushima No. 1, located on the Pacific coast, two to three times more than when it was actually generating electricity.

On a recent workday, about 100 workers were dismantling a makeshift roof over one of the reactor buildings, while about a dozen others were removing fuel rods from a cooling pool. Most of the rest were dealing with contaminated water-related work, said Tatsuhiro Yamagishi, a spokesman for plant operator Tokyo Electric Power Co.

The work threatens to exhaust the supply of workers for other tasks, since they must stop working when they reach annual radiation exposure limits. Experts say it is crucial to reduce the amount and radioactivity of the contaminated water to decrease the risk of exposure to workers and the environmental impact before the decommissioning work gets closer to the highly contaminated core area.

40 years

The plant has six reactors, three of which were offline when disaster struck on March 11, 2011, a magnitude-9.0 earthquake that triggered huge tsunami that swept into the plant and knocked out its backup power and cooling systems, leading to core meltdowns in the three active reactors.

Decommissioning and dismantling all six of the reactors is a delicate, time-consuming process that includes removing the melted fuel from a highly radioactive environment as well as all the extra fuel rods, which sit in cooling pools situated at the top of the reactor buildings.

The entire job still requires finding out the exact conditions of the melted fuel debris and developing remote-controlled and radiation-resistant robotics to deal with them, and the work is expected to take at least 40 years.

500,000 tons

The main problem is an abundant inflow of groundwater into the contaminated water that doubles the volume and spreads it to vast areas of the compound. Workers have jury-rigged a pipe-and-hose system to continuously pump water into the reactors to cool the clumps of melted fuel inside.

The water becomes contaminated upon exposure to the radioactive fuel, and much of it pours into the reactor and turbine basements, and maintenance trenches that extend to the Pacific Ocean. The plant recycles some of the contaminated water as cooling water after partially treating it, but groundwater is also flowing into the damaged reactor buildings and mixing with contaminated water, creating a huge excess that needs to be pumped out.

So far, more than 500,000 tons of radioactive water have been stored in nearly 1,000 large tanks that workers have built, which now cover most of the sprawling plant premises. After a series of leaks from the storage tanks last year, they are now being replaced with costlier welded tanks.

That dwarfs the 9,000 tons of contaminated water produced during the 1979 partial meltdown at Three Mile Island in the United States. In that incident, it took 14 years for the water to evaporate, said Lake Barrett, a retired U.S. nuclear regulatory official who was part of the early mitigation team there and has visited Fukushima No. 1.

“This is a much more complex, much more difficult water management problem,” Barrett said.

¥10 trillion

An estimated ¥2 trillion will be needed just for decontamination and other mitigation of the water problem. Altogether, the entire decommissioning process, including compensation for area residents, reportedly will cost about ¥10 trillion.

All this for a plant that will never produce a kilowatt of energy again.

The work threatens to exhaust the supply of workers for other tasks, since they must stop working when they reach annual radiation exposure limits. About 500 workers are digging deep holes in preparation to build a taxpayer-funded ¥32 billion underground “frozen wall” around the four reactors and their turbine buildings to try to keep the contaminated water from seeping out.

Tepco is developing systems to try to remove most radioactive elements from the water. One, the Advanced Liquid Processing System (ALPS), has been trouble-plagued, but utility officials hope to achieve a daily capacity of 2,000 tons when it enters full operation next month. Officials hope to be able to treat all contaminated water by the end of March, but that is far from certain.

The Guardian, Nov. 13, 2014: The man in charge of cleaning up the wrecked Fukushima Daiichi nuclear power plant has admitted there is little cause for optimism… The water problem is so severe that [Tepco has] enlisted almost all of their 6,000 workers… to bring it under control… “ I have no intention of being optimistic” [Fukushima Daiichi’s manager Akira Ono] told the Guardian… large quantities [of contaminated water] find their way to other parts of the site, including maintenance trenches connected to the sea… “The contaminated water is the most pressing issue – there is no doubt about that,” Ono said… “I cannot say exactly when, I hope things start getting better when the measures start taking effect.”
