Following up this article.. [Elephant foot ?] Tepco collected highly radioactive sediment in reactor2 PCV, “0.2 Sv/h of γ and β” [URL]
Zirconium was identified in the substance taken from reactor2 PCV. Zirconium is used for the fuel clad and channel box.
The substance was coincidentally found inside of the PCV at 9.6m from the surface. This proves fuel clad or channel box was also molten in reactor2 and scattered in PCV.
Tepco stated they won’t conduct the additional detailed analysis to reject the further inspection.
Tepco gave up air cooling plan / The state of molten fuel not known

On 9/29/2013, Fukushima Diary reported Tepco was studying the feasibility of air-cooling the reactors.
(cf, [Column] Tepco and JP Gov’s “blank” plan to decommission Fukushima nuclear plant in 40 years [URL])
2 months have passed and on 11/28/2013, Tepco announced they cannot realize the air cooling plan for the absence of technology.
In order to cool reactor1 ~ 3, they need to inject approx. 5,000 ~ 9,000 m3/h of air (25℃) to each reactor.
However, they don’t know the location, shape, surface area, volume and the state of surface of the molten fuel. Also, 4 of 5 nozzles can’t reach the possible fuel. The only nozzle that may reach the fuel is too far. They therefore need to install the pipes inside of the vessels, which is extremely challenging at the current technical level.
Fukushima plant radiation increasing due to the rising contaminated groundwater / “Covering with lead plate”

Related to this article.. Tepco gave up pumping up the rising contaminated groundwater on the seaside of reactor3 / “No tank capacity” [URL]
The atmospheric dose of the seaside of Fukushima plant is increasing due to the rising contaminated groundwater, according to Tepco.
Tepco is building the underground wall on the coastal line, but the exposure dose of the workers is going up.
Tepco states as they build the underground wall, highly contaminated groundwater is coming up to the surface of the ground.
In order to keep building walls, the workers are operating on the “stand” to be as far from the ground as possible and also use the lead plate.

On 11/28/2013, Tepco announced they won’t pump up the contaminated groundwater anymore in the seaside of between reactor2 and 3.
Having the highly contaminated groundwater flowing to the sea, Tepco is building the underground wall on the coastal line.
However the groundwater level rapidly increases due to the wall, Tepco needed to pump up the groundwater on the seaside of reactor2.
On the seaside of reactor3, Tepco is also building the underground wall but because of the shortage of the tanks, Tepco decided not to pump up the rising groundwater.
By not pumping up the groundwater, it may come up to the surface of the ground or overflow the underground wall to the sea.
Tepco states the radioactive density of the water is low enough.

Tokyo Suburb To Be Decontaminated, 70% Of Town Marked For Clean Up
Toride City, a suburb of Tokyo was declared in need of decontamination after 70% of the city was found to potentially be contaminated above allowable levels. Surveys are being conducted to determine what homes require decontamination. Hot spots were found around Chiba, also considered to be a suburban part of Tokyo, requiring response from the government to do clean up there. PM Abe and other government officials have insisted Tokyo is not contaminated at all and … Read entire article »
Fukushima Radiation Exceeds Chernobyl Evacuation Levels Across Japan
The contamination from Fukushima did not fall in concentric circles as the evacuation zones imply. Contamination from the disaster is also not uniform is where it concentrates. By comparing the Chernobyl evacuation zone standards to the contamination levels in Japan it gave a startling view of the problem. The USSR was never faulted for being overly cautious in their evacuation … Read entire article »
