TEPCO To Remove Cover On Unit 1 This Fall
[Translate] TEPCO will remove the cover on unit 1 at Fukushima Daiichi this fall. The cover was hastily put over the unit in 2011 in an attempt to lower releases. TEPCO did not say why this work has suddenly been jumped ahead of other work. Most of the roadmap plans TEPCO has announced put unit 1 far down the list of priorities. To remove the spent fuel TEPCO will need to remove the cover, something they say will raise radiation levels. They will also need to remove the remains of the roof and the two cranes to do the work. It was not mentioned how much the radiation levels would rise during this work. Meanwhile the Japanese government has been pushing to reclassify more and more areas near the plant as being … Read entire article »

Highly Radioactive Debris Found On Unit 3 Refueling Floor
[Translate] TEPCO has announced that a piece of highly radioactive debris has been pulled off of the refueling floor of unit 3. The object read 540 mSv/h and was removed by robotic equipment. So far no photos of the object or description of where on the refueling floor it was found have been provided by TEPCO. Ex-SKF has full translations of the two TEPCO statements. We have been monitoring the progress of the refueling floor debris removal. As of last week they were nearing the area over the reactor well. These photos show where they were in the clean up last week.

Current Challenges & Progress At Fukushima Daiichi
[Translate] TEPCO’s testing of the ALPS system intended to remove all contamination except tritium continues but now it is not expected to be out of the testing phase until fall 2013 at the earliest. TEPCO also admitted that the system is not completely removing contaminants as expected and the radiation levels around the equipment was rising. Right now neither issue was halting work but could become a problem over time if not resolved. This throws a huge problem into the contaminated water problems. TEPCO currently has no plan do deal with this issue. They have begun building more tanks on site and still hope to use the groundwater bypass system but that has not been approved or fully implemented. The radiation increases around ALPS could cause a bigger problem down the road if the … Read entire article »

Sisyphus With A Paper Cup; TEPCO’s Enormous Water Problem
[Translate] The contaminated water problems at Fukushima Daiichi have been plaguing the plant since day one. In recent months the problems have once again shown themselves to be too much for TEPCO to deal with while the plant continues to contaminate the environment. TEPCO stated that they were again, out of space only to find space after it became apparent the government would not allow them to dump contaminated water into the Pacific Ocean. This is something TEPCO has asked to do repeatedly since 2011 when they dumped contaminated water into the Pacific on top of what has been leaking. Contamination and contaminated water from the failed reactors is still making its way out of the plant a number of ways, all with long term major implications for the environment and public … Read entire article »

Rats Vs. TEPCO, The Rats Are Winning
[Translate] TEPCO’s new arch nemesis, the influx of rats that have taken up residence at the plant, are causing more problems. Two rats were found dead inside the electrical equipment being used to power unit 2′s spent fuel pool cooling system. This time it didn’t knock out power to the system but did require the cooling system be shut down for most of a day to work on the electrical box. TEPCO cleaned out the box and applied some sort of putty or foam around the entry point of the wires. Unless this material has steel wool or something similar in it to deter rats or mice from chewing, it may not be an effective solution. The IAEA recently inspected the plant, declared nothing of substance and suggested TEPCO continue to handle the disaster … Read entire article »

Strontium 90 Will Contaminate Coastal Groundwater In 10 Years
[Translate] Strontium 90 found to be leaking out of the ponds installed by TEPCO is expected to contaminate the coastal groundwater near the plant in 10 years. Kyodo News cites the NRA for this statistic. Certain ponds at the plant held the backwash sludge water from the reverse osmosis system, adding to the high levels of contaminants in the water.

Fukushima Nuclear News Roundup – Monday April 15, 2013
[Translate] TEPCO is still not ruling out the option of dumping radioactive water into the ocean. Something that would cause obvious outrage from fishing groups, environmentalists and other nations. TEPCO admits the big challenge in trying to locate the radioactive leaks in the holding ponds on site. The high radiation levels prevent humans from inspecting the tanks in detail. The IAEA is heading to Fukushima Daiichi to inspect the disaster response at the plant. After a series of failures that are being cited as the reason for the trip it isn’t clear what the IAEA will do beyond another photo op. Hirano Fukushima, part of the evacuation zone that has been reopened will begin farming rice again. Experimental farming last year showed contamination levels were below the government 100 bq/kg levels. The article cites … Read entire article »

Water Leaks At Daiichi Expose New Widescale Failures At TEPCO
[Translate] The extent of the problems at Fukushima Daiichi has come to light in the past few weeks as multiple failures ended up in the news. NRA is expressing their concern. The NRA head commented that the water situation at Daiichi is on the verge of collapse but that there is no choice but to keep adding water to the reactors. A recent Japan Today article cites the reason for TEPCO’s design choices for the storage ponds was cost, they were cheaper. Maeda, the company that built the ponds blames TEPCO’s design choices for the problem and declared that TEPCO drew up the plan, not Maeda. There have also been questions raised why TEPCO chose what was a landfill design for solid waste debris for ponds intended to hold contaminated water. TEPCO … Read entire article »

More Problems Come To Light At Fukushima Daiichi
[Translate] More information has come out today in relation to the pond failures and leaks at Fukushima Daiichi. Third confirmed pond leaking but all are leaking We documented the issue of all of the ponds leaking yesterday based on TEPCO’s reporting. Asahi Shimbun has come to the same conclusion today. TEPCO has admitted to the press that a third pond is leaking. Now the number one pond is leaking according to TEPCO. This is the pond that has been receiving water from the number two pond where the first leak was declared. The NRA has asked TEPCO to monitor the leaks and to prevent the water from flowing off the premises. This appears to be the extent of NRA’s involvement in the pond construction and ongoing oversight of them. TEPCO claims water may not leak … Read entire article »

Pre-Tsunami Damage At Unit 1 Fukushima Daiichi
[Translate] Concerns about damage to unit 1 and possibly other units having happened before the tsunami hit the plant still exist among experts and those who witnessed the disaster. Many worked cited seeing pipes buckle, break, leak or fall off of walls as they fled the unit during the earthquake. In an effort to document these events and investigate the possibility of earthquake induced damage playing a role in the disaster we have started a page to document those findings.

Pond Liner Used At Fukushima Daiichi Equal To Trash Bag Plastic
[Translate] Asahi Shimbun mentions in one of their reports on the pond tank leakage at Fukushima Daiichi that the HDPE plastic sheet being used on the ponds as lining material is 1.5mil plastic. “The underground storage tank–60 meters long, 53 meters wide and 6 meters deep–is lined with an outer 6.4 millimeter-thick layer of clay, and topped by two layers of polyethylene sheets, each 1.5 millimeters thick.” This would be a total of 3 mil plastic. Other reports mentioned there might be 3 layers of plastic sheet used, that would only make it 4.5 mil thick. For some contrast trash bags used to line trash cans are frequently 1.5 mil or thicker. Liner used for koi ponds or commercial lakes is 20 mil thick. Other koi pond liners found that are also cited as being suitable … Read entire article »

Company Involved In Decontamination Scandal Built Daiichi Pit Tanks
[Translate] The company that built the now leaking pit tanks at Fukushima Daiichi was also involved in the recent scandal involving decontamination work being done around Fukushima Prefecture. Asahi Shimbun found construction companies hired to try to clean up areas of high radiation were dumping leaves and soil into ditches and streams creating an even bigger problem. One of the companies found to be doing this is Maeda Construction. Maeda was also working on some zeolite absorption projects as part of the prefecture decontamination work. The company has been in business since 1919 and has done various large scale projects such as dams and airports. Maeda Construction built the pit tanks at Fukushima Daiichi. Maeda is also building the sea wall at Fukushima Daiichi. The tanks original purpose was to hold less contaminated water … Read entire article »

ANOTHER Leak In A Pit Tank At Fukushima Daiichi
[Translate] TEPCO is now reporting another leak in one of the pit tanks at Fukushima Daiichi. The number 3 pit tank has now been found to be leaking and strontium was found outside the tank. TEPCO claims only 3 liters of water has leaked from this tank but fails to explain how such a small amount of water vs. a huge tank could be determined. The number 3 tank sits next to the number 2 tank TEPCO admitted was leaking large amounts of highly contaminated water on Friday. The water held in the number 3 tank is the same type as in the number 2 tank. Jiji is reporting that the radiation levels around the number 2 tank are rising. TEPCO claims they have set up an emergency task force to deal … Read entire article »

Update On Water Leak At Fukushima Daiichi
[Translate] We documented the early information on the radioactive water leak at Daiichi here. TEPCO and the Japanese media have released some additional information on the situation. TEPCO still insists they don’t think the water has reached the sea but the only reason they give is because there isn’t a drainage ditch nearby. Kyodo News reports TEPCO thinks the transfer to the other tank will take 5 days. TEPCO has added multiple pumps to try to expedite the process. What is not mentioned is that this effort now ruins another “clean” water tank TEPCO intended to use for storing the cleaner water produced by the ALPS system once it is in operation. The Asahi Shimbun report cites from TEPCO that the water that leaked was about 710 billion becquerels. They do think it … Read entire article »

High Level Water Leak At Fukushima Daiichi
[Translate] Update: Reporting from various sources that were following the press conference. TEPCO plans to move the water from the leaking tank (#2) to another underground tank (#1). TEPCO refers to them as tanks but they are the lined pools. They think it could take 2 weeks to completely transfer the water. The leaking pool sits 800 meters from the sea. They don’t think it is leaking to the sea by way of drainage ditches but said they have no way of preventing it from happening since the leak is underground. Update: TEPCO admits that 100 tons of highly contaminated water may have leaked out of the pond. Fukushima Diary has been monitoring the press conference and provided an exchange between the TEPCO rep and a reporter from Asahi where TEPCO admits … Read entire article »

New Power Outage Caused By Workers
[Translate] Workers were installing a piece of wire mesh inside an energized high voltage panel at Fukushima Daiichi in an attempt to prevent rats from getting into the equipment. Rats caused the days long outage last month after one crossed an electrical circuit and took out power to a large portion of the plant. The attempt to install metal mesh on a live electrical system caused the box to ground knocking power offline to unit 3′s spent fuel pool cooling for three hours. TEPCO provided no explanation why workers were working inside a live power panel, so far no reports of anyone being injured.
