Fukushima Daiichi Frozen Wall Begins Freezing Operations

Fukushima Daiichi Frozen Wall Begins Freezing Operations

TEPCO’s contractors have begun the process of freezing the completed sections of the frozen wall. Blocks 1-8 are currently in the freezing process. Other sections are either still under construction or in the process of having the plumbing installed. The sections currently being frozen include the land side and north sides of the reactor building areas.

Fukushima Daiichi Port Concreting Completed

Work to put down a coat of concrete across the entire port floor at Fukushima Daiichi has been completed. Initial work in 2012 did sections closer to the reactor building. Efforts that just wrapped up this week covered the remaining sections of the port floor. Since this last round of concrete work began operation we have seen the level of contamination in fish in the port decrease. There is some skepticism that TEPCO’s fish testing has not been 100% accurate, but the fish readings could be tied to this port work. TEPCO never clearly said what mechanism they were attempting to seal off. If this was to seal in sediment that contained contamination and potentially fuel fragments or if it was to seal leak routes into the port.

TEPCO Refused To Upgrade From Windows XP At Fukushima Daiichi

TEPCO Refused To Upgrade From Windows XP At Fukushima Daiichi

Japan’s NRA has publicly urged TEPCO to upgrade computer systems used at Fukushima Daiichi, and possibly company wide. NRA pointed out the lack of current security updates in Windows XP created a significant security risk. The regulator urged TEPCO to stop being cheap and do the needed computer upgrades. After the public flogging a TEPCO representative said the company would move up the date for potential computer upgrades but didn’t say when they would be … 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 Unit 3 Spent Fuel Pool Gate Inspected

Fukushima Daiichi Unit 3 Spent Fuel Pool Gate Inspected

The unit 3 spent fuel pool gate was inspected further after concerns that the fuel handling crane could have damaged the gate. The inspections produced a number of photos of the condition of the gates.   This overhead view shows the two gates for the spent fuel pool along with the concrete reactor cover from above. The G2 gate is clearly dislodged from the normal position. This could have been the result of the blast during the meltdown. … Read entire article »

University Does Undisclosed Scans Of Fukushima Daiichi

These scans were never mentioned in any TEPCO literature, none of IRID’s documents nor METI’s reports on the Fukushima Daiichi disaster. Kyodo News announced today that Nagoya University conducted five muon scans on reactors 2 and 5 between April and July of 2014. They compared the two reactors and concluded that unit 2 “melted down”.

Fukushima; A Sign Lays Bare A Toxic Relationship

When Yuji Onuma was in 6th grade he wrote a phrase. What started as part of a homework project, won an award and eventually became the slogan on large signs as you enter Futaba Fukushima. “Nuclear power the energy of a promising future“ The now ironic signs are to be torn down. The town claims the signs are a safety risk as they have deteriorated. Mr. Onuma wants the signs to stay. “The signboards should be preserved as … Read entire article »

Fukushima Daiichi Workers Urged To Participate In Govt. Study

The Japanese government has decided to allow RERF  (Radiation Effects Research Foundation) to do an epidemiological study on the workers from Fukushima Daiichi. This would be a study only, it would not include giving them any needed medical care.

Fukushima Daiichi Discharge Canal Sees Large Contamination Increase

Fukushima Daiichi Discharge Canal Sees Large Contamination Increase

We previously reported about increases at the unit 1 discharge canal back in February. The highs back then were in the 4 digit range.

TEPCO Admits Recent Leaks Came From Contaminated Water Tanks

TEPCO admitted that water recently leaked from the H4 tank farm is loose in the groundwater at the plant. Monitoring wells installed downstream after the first major leak from these tanks, found a spike to 11,000 bq/liter in well E-9. Earlier in the last month, a drainage canal nearby alarmed when highly radioactive water was found in it but TEPCO insisted this had nothing to do with the nearby tanks.

Fukushima Melted Fuel Removal Process Being Reconsidered

Fukushima Melted Fuel Removal Process Being Reconsidered

The Decommissioning Facilitation Corporation is reconsidering the approach to be used for removing melted fuel at Fukushima Daiichi. The early established plan was to try to fill the containment structures with water and retrieve the melted fuel with robotic equipment through the top of the reactor via the reactor well. Last year IRID (International Research Institute for Nuclear Decommissioning) questioned this approach and urged that an alternative option be established in case the flooding plan would not … Read entire article »

It has been four years since the massive triple disaster struck Japan. In some ways much has changed, in others, problems continue to drag on. Over the last year TEPCO managed to finally remove all of the spent fuel from the unit 4 spent fuel pool. This serious risk has now been removed with the fuel residing in the much safer common fuel pool. TEPCO has since focused work on steps needed to prepare for … Read entire article »

2nd Mobile Strontium 90 Filter System In Service At Fukushima Daiichi

A second mobile strontium 90 filtration system is in service at Fukushima Daiichi after initial testing. The portable system housed in modified shipping containers are being used to filter out strontium 90 from contaminated water sitting in tanks. The systems can remove most of the strontium 90 from the contaminated water. This considerably reduces this type of contamination and further reduces some of the risk factors involving the massive tank farms on site. TEPCO has not … Read entire article »
