Prefabricated Tanks Installed At Fukushima Daiichi

Prefabricated Tanks Installed At Fukushima Daiichi

As part of the efforts by the government and METI to improve the contaminated water problem at Fukushima Daiichi new tanks have been being installed. Some tanks were welded together on site. A new set of tanks is being prefabricated elsewhere and shipped to the plant for installation. The pre-assembled tanks are put together and shipped by barge to the plant where they are transferred by crane to a flat bed trailer and driven to the … Read entire article »

Fukushima Highly Radioactive Water Accidentally Released From Reactor Basement

Fukushima Highly Radioactive Water Accidentally Released From Reactor Basement

TEPCO has admitted that highly radioactive water from reactor building basements was pumped out of the buildings into the basements of other buildings. In order to do this workers would have had to manually operate the pumps. These pumps are used to reverse water into the reactor buildings or send it to other destinations. They are still investigating how the incident happened. Asahi Shimbun cited the water as being contaminated with tens of millions of … Read entire article »

Fukushima Unit 1 To Undergo Spent Fuel Pool Desalination

TEPCO reported they will now remove the salt from the unit 1 spent fuel pool. Maybe you are asking why now, over 3 years later are they just getting around to this? We wondered the same thing. In reviewing our older notes it appears TEPCO may not have added any water to the unit 1 spent fuel pool during those early days where they were forced to use sea water for cooling at the plant, … Read entire article »

TEPCO To Resume Dumping Groundwater Into The Sea At Fukushima Daiichi

TEPCO To Resume Dumping Groundwater Into The Sea At Fukushima Daiichi

TEPCO has obtained permission from two local fishing cooperatives to dump contaminated groundwater into the Pacific. The cooperatives said they did want a third party to monitor the releases and radiation levels. It was not mentioned who would be that third party. TEPCO insists that the water would have “below 1 bq/liter” of cesium. They didn’t mention here how much strontium 90 or tritium the water could contain but those would likely be below the legal … Read entire article »

METI Working On Tritium Disposal For Fukushima Daiichi

METI Working On Tritium Disposal For Fukushima Daiichi

While the IAEA is busy trying to convince the public yet again that TEPCO should dump contaminated water into the sea, METI has been working on plans to store or dispose of the tritium laced water. In a March 14 set of reports METI documented their plans for potential tritium disposal. The post ALPS water will require removal of iodine 129 and cobalt 60 before it can be handled as tritium only water. METI operates under … Read entire article »

23 Tbq Water Leak At Fukushima Caused By Multiple Human Errors

23 Tbq Water Leak At Fukushima Caused By Multiple Human Errors

100 tons of water leaked from a contaminated water tank at Fukushima Daiichi after workers incorrectly aligned valves. They then ignored the alarm that alerted them to a tank that was not supposed to be filling, had overfilled. After the tank spilled out over the top flange the water then leaked out through a failure in the water weir that is supposed to catch any leaks. This water is highly radioactive water left over from … Read entire article »

High Levels Of Radiation Found In Fukushima Unit 3 Turbine Building

High Levels Of Radiation Found In Fukushima Unit 3 Turbine Building

TEPCO released radiation readings for water inside the unit 3 turbine building this week. The readings were from December 2013. TEPCO used them as a comparison to show a water leak elsewhere in the building was not reactor water. The readings themselves are a rare find as TEPCO doesn’t usually release this data. The readings are disturbingly high.

TEPCO released readings for two seafront wells that have not been published before. Wells 1-2 and 1-3 were not on any older reports from before January.These are the first strontium 90 readings for these wells. The strontium 90  reading for well 1-2 was 5,000,000 bq/liter dated July 5, 2013. The “all beta” reading for the same date was actually lower than the strontium 90 alone at 900,000 bq/liter.

Fukushima Unit 2 Torus Ultrasound Finds Internal Water Level

Fukushima Unit 2 Torus Ultrasound Finds Internal Water Level

The ultrasound robot has been run inside unit 2 to attempt to determine the water level for the torus tube. It found that the torus does contain water and it sits just slightly below the water level of the torus room. The levels are 10-30mm below the room water level. Readings were taken over 3 consecutive days. The level indicates that water either does not flow into the torus or the torus tube is no … Read entire article »

How Fukushima Leaks

The mainstream media, late to the game has confused the leaking at Fukushima. Some reported as it if has not actually happened yet. Here are the ways Fukushima Daiichi leaks. 1. Constant leaks The ancient underground river that flows beneath the plant is assumed to move 1000 tons of water under the plant and most of it out to sea every day. TEPCO pulls 400 tons of that out of the reactor buildings daily as it mixes with the contaminated water in the buildings. The remaining 600 tons is assumed to flow out to sea each day with some of it becoming contaminated. Marine scientists have cited these types of ongoing leaks as the reason cesium levels in fish in the region have failed to decrease. This leak route is assumed to … Read entire article »

Fuku Leaks

Now that the truth is at least partially public knowledge, the Japanese government is stepping in to help at Fukushima Daiichi. This may not be as great as it sounds. The plant is leaking to the sea, the question is how much. The reality is nobody knows right now. This is due to two things. One, where the plant is leaking is not fully known or if it is known by TEPCO they are not telling anyone. Two, the condition and location of the melted fuel is either not fully known or not disclosed by TEPCO. There is reason to suspect that at least some of the melted fuel is outside of containment. It is known that the water put into the reactors and groundwater that flows into the reactor buildings … Read entire article »

Where & How Fukushima Daiichi Leaks

After the new round of contaminated water leaks were admitted by TEPCO, we revisited the technical design of the buildings and where they could leak from. The buildings themselves are not as solid and contained as one would assume. Even the containment structure has hundreds of “holes” in it for pipes, cabling and the torus vents to pass through. These are sealed to prevent leaks but the penetration seal materials can melt or otherwise fail. Worker Happy11311 mentions exactly how many penetration holes are in the outer reactor building walls. Happy’s tweet, machine translated to English. If there are 590 building penetrations that are below the groundwater level, each of those provides a potential route out for contaminated water. The groundwater height is about 3000 OP as seen with the blue line … Read entire article »
