1 Billion USD Lawsuit Over Hitachi Fukushima Cleanup Contracts

1 Billion USD Lawsuit Over Hitachi Fukushima Cleanup Contracts

Purolite company based in the US has sued Hitachi for 1 billion USD in a US court over theft of intellectual property. The suit alleges that Hitachi signed on to a joint venture to develop contaminated water systems for Fukushima Daiichi back in 2011 or 2012. Once Hitachi had the proprietary technical information from Purolite they signed on to work on the project with AVANtech, also a US company, according to the allegation in the … Read entire article »

NRA Tells TEPCO To Reduce Radioactive Water In Reactor Buildings At Fukushima

NRA Tells TEPCO To Reduce Radioactive Water In Reactor Buildings At Fukushima

NRA has instructed TEPCO to deal with the radioactive water in the reactor building basements at Fukushima Daiichi. The request included reducing the radioactive contamination in the water and also the volume. The addition of more holding tanks was included in the request. NRA appears to be concerned with contaminated water leaking out of the reactor buildings or being flushed out by a tsunami at the plant. Current ground water levels around the reactor buildings had trended … Read entire article »

TEPCO Curiously Avoids Prosecution On Contaminated Water Leak

TEPCO Curiously Avoids Prosecution On Contaminated Water Leak

A court case that went after TEPCO for causing a major contaminated water leak, part of which leaked to the sea, was dismissed last week. Prosecutors claimed there was no proof contaminated groundwater leaked to the Pacific. The water that did immediately reach the sea did so through the existing drainage canal systems at the plant. After Japan’s NRA slapped an INES disaster rating on the leak, TEPCO then took steps to control and monitor the … Read entire article »

Two New Leaks At Fukushima Daiichi

Two New Leaks At Fukushima Daiichi

Two new leaks happened at Fukushima Daiichi recently. Both were contained within the buildings where they happened. The first was a leak within one of the ALPS filtration buildings. A flange on a pipe containing highly radioactive water began to leak. Tightening of the bolts on the flange solved the leak. TEPCO states that the small amount of water remained within the spill containment weir.   A pipe in the new incinerator building leaked. This seemed unusual since the … Read entire article »

Fukushima Tritium Removal Technology Moves To Next Phase

Fukushima Tritium Removal Technology Moves To Next Phase

Industry insiders and the IAEA told Japan to just dump their tritium laced water at Fukushima Daiichi into the Pacific. Japan instead continued to look for a potential solution. With an 8.6 million dollar METI grant Kurion is going to scale up their initial design for a tritium removal system. This work is towards eventually having a functioning system that could be deployed at Fukushima Daiichi. While actual results of the first phase have not been … Read entire article »

Fukushima Radiation Found In Tap Water Around Japan

Fukushima Radiation Found In Tap Water Around Japan

Testing conducted in February and March of 2015 found cesium in many tap water samples collected around Japan. While the numbers were fairly low it is still a persistent problem since tap water is used in some way in everything that is consumed. In the readings, Tokyo had higher tap water contamination levels than Fukushima City. One reading that may cause confusion is the reading for Ichihara Chiba. It indicated iodine 131 was found in that … Read entire article »

Unit 1 Basement Shows Highly Contaminated Water Remains

Unit 1 Basement Shows Highly Contaminated Water Remains

TEPCO is making an effort to lower the water level in some of the basement rooms of the unit 1 reactor buildings. As groundwater has been pumped up via the outdoor subdrain pits, this has created a situation where the standing water in the basements could end up higher than the surrounding groundwater. This could lead to more contaminated water leaking out of the buildings. TEPCO is installing more water level monitoring sensors to better … Read entire article »

Fukushima Daiichi Updates From IRID Part 3; Testing The Goo

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.

TEPCO To Try Two New Tactics To Stem Radioactive Tide At Fukushima Daiichi

Efforts to freeze a trench near unit 2 in order to remove highly radioactive water has continued to have problems. The ice wall system wasn’t working so TEPCO dropped ice and then dry ice into the trench via a small pipe. They then discovered that the dry ice was clogging in the small pipe they were using to drop ice down by the shovel full.

TEPCO hopes to have two new installations of ALPS completed in September and October of this year. The company is also now claiming that the current system has been able to remove considerable amounts of additional types of radiation down to below regulatory limits, though amounts of these isotopes still exist in the water. The water would also still contain tritium, something ALPS can not remove. By adding additional tanks and changing a filter media being … Read entire article »
