Fukushima Groundwater Contamination Rises To Nearly Double Previous Reading

Fukushima Groundwater Contamination Rises To Nearly Double Previous Reading

Seafront well 1-6 began to rise again after it had begun to drop after the most recent typhoon. It nearly doubled, from 1.4 million bq/liter of beta radiation on the 23rd up to 2.5 million bq/liter on the 27th. TEPCO gave no reason for the jump. This grouping of monitoring wells is assumed to be located in the path of the underground plume of highly contaminated water from unit 1. They are also located near the … Read entire article »

ALPS 2.0 Begins Test Operations At Fukushima Daiichi

ALPS 2.0 Begins Test Operations At Fukushima Daiichi

The new and improved version of ALPS has begun test operations. TEPCO announced the first of the two units has begun test operations. The second will go into testing mode in October. These new units build on the lessons learned from the ongoing failures of the initial ALPS systems. Better materials, coatings and safety systems have been used to try to overcome the problems found in the original units. TEPCO hopes to be able to treat … Read entire article »

2nd ALPS Decontamination System Installed At Fukushima Daiichi

2nd ALPS Decontamination System Installed At Fukushima Daiichi

A second ALPS decontamination system is being installed at Fukushima Daiichi and will begin test operations in early September. NRA announced the new system yesterday. The first ALPS system, designed by Toshiba has been plagued with problems that required around a year of testing operations to make it work properly. Another system in testing phases at the plant is a new Hitachi system that would remove some of the isotopes that ALPS can not. image credit | … Read entire article »

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

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. This caused TEPCO to stop all work because apparently ice … Read entire article »

Fukushima Contaminated Water Problems Worsen

Fukushima Contaminated Water Problems Worsen

TEPCO announced this week that they wanted to begin pumping up water from the sub drains near the reactor buildings. This comes as they were also admitting the efforts to freeze the trench were not going well. TEPCO’s plan would included decontaminating this water before dumping it into the sea. The disaster site has struggled with water decontamination for years and just announced recently that they think they finally have the ALPS decontamination system operational. None … Read entire article »

TEPCO Claims ALPS Decontamination System To Be Operational By End Of Year

TEPCO Claims ALPS Decontamination System To Be Operational By End Of Year

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 »

TEPCO’s Bolt Together Tanks Were Known To Leak Before Installation

The manufacturer that sold TEPCO used bolt together tanks for use at Fukushima Daiichi said that the tanks were known to not be leak proof. The tanks, made to hold construction mud were not made for holding dangerous liquids. Instead they were used as temporary solutions on construction sites for holding mud. TEPCO purchased a number of both used and new tanks, the company said they never guaranteed the used tanks for 5 years as … Read entire article »

Welded Water Tanks Installed At Fukushima Daiichi

Welded Water Tanks Installed At Fukushima Daiichi

Welded water tanks to replace the miles of leaking bolt together tanks at Fukushima Daiichi are being installed. The tanks are welded off site and shipped in by barge, ready to install. This allows workers to do the bulk of the work somewhere safe, leaving only the final move and installation to be done in the radioactive areas. This does make one wonder why TEPCO hadn’t thought of this themselves when the first tanks were … Read entire article »

TEPCO Admits Deep Groundwater Contamination & Leak To Sea

TEPCO Admits Deep Groundwater Contamination & Leak To Sea

TEPCO has been doing further groundwater investigations at the plant including testing for contamination at various depths to understand what layers are carrying most of the contamination. They now admit that contamination can make it into the deep groundwater layer and could be leaking out to sea. This is something both the NRA and various researchers have speculated since early this year. TEPCO noted that the pressure in the deep layer is less than the water … Read entire article »

NRA Discovers Major Radioactive Tank Leak At Fukushima Daiichi

NRA Discovers Major Radioactive Tank Leak At Fukushima Daiichi

TEPCO missed it but NRA officials that were at the plant found a 4 ton leak of radioactive water. Not only did the water leak out of a set of tanks, it leaked out of the barrier intended to contain it. Apparently a drain valve was left open on the barrier. This is how the first major tank leak at the H4 tank farm happened. TEPCO had insisted they cleaned up their act and had … 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 »

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.

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.

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.
