Desperate Tepco to drop ice and dry ice to help “frozen wall” be frozen

Preceding “frozen” water wall not frozen over 2 months – Video [URL]

On 7/7/2014, Tepco admitted the preceding “frozen” water wall hasn’t gotten frozen over 2 months after the operation.

They installed the coolant packers at 2 locations of underground trench of the seaside of Reactor2 in the end of April and June but neither of them have been frozen.

As the reason, Tepco comments the water flow is preventing it from frozen. Tepco plans to install additional packers and grout and announces they can still complete freezing the wall by the end of September.

On 7/23/2014, Tepco announced they are going to drop ice and dry ice to the unfrozen “frozen wall”.

It’s becoming nearly 3 months, but the preceding frozen wall hasn’t gotten frozen as planned.

Japanese government and Tepco have only 3 measures against contaminated water. Frozen water wall is one of them. They need it to be successfully working so the government of Japan can look like they are controlling the situation.

From Tepco’s report submitted to NRA (Nuclear Regulation Authority), they are already prepared to drop 2 t of ice and 1 t of dry ice for 3 days starting on 7/24/2014.

Depending on the temperature, they are going to drop 5.4 t of ice per day from the end of July. They expect to complete the frozen wall by mid August.

There is a possibility that the retained contaminated water may overflow if they drop ice and dry ice. Also it is not clear how it is supposed to reinforce the frozen water.

However there are not many options left for Tepco.

Landsat's global perspective on natural disasters, urban change and more

On July 23rd, 1972, the first Landsat spacecraft launched into orbit. At the time, it was called “Earth Resources Technology Satellite,” or ERTS, and was the first satellite to use a scanning spectrophotometer. Previous satellites relied on film cameras (ejecting the exposed film to be caught by planes) or transmitted the signal from television cameras. The scanning sensor and its successor sensors on subsequent Landsat satellites revolutionized how we study our home planet.Celebrating this anniversary, this video is a “greatest hits” montage of Landsat data. Throughout the decades, Landsat satellites have given us a detailed view of the changes to Earth’s land surface. By collecting data in multiple wavelength regions, including thermal infrared wavelengths, the La… »

Ministry of Land awarded a Fukushima river a prize of the clearest river in Japan

Arakawa river in Fukushima city was awarded a prize as the clearest river in Japan by Ministry of Land, Infrastructure, Transport and Tourism.

On 7/22/2014, Ministry of Land, Infrastructure, Transport and Tourism announced this. Arakawa river has been chosen to be the clearest river among 163 Japanese rivers for 4 continuous years.

It was not judged by radioactive material density but judged by biochemical oxygen demand from January to December of 2013. In the announcement, radioactive material was never mentioned.

Fermi catches a never before seen 'transformer' neutron star

In late June 2013 astronomers using Fermi Gamma-ray Space Telescope observed an exceptional binary containing a rapidly spinning neutron star which suddenly underwent a dramatic change in behavior. The pulsar’s radio beacon vanished, while at the same time the system brightened fivefold in gamma rays, the most powerful form of light.Benjamin Stappers, an astrophysicist at the University of Manchester, England, who led an international effort to understand this striking transformation, said it was as if someone had flipped a switch, morphing the system from a lower-energy state to a higher-energy one.”The change appears to reflect an erratic interaction between the pulsar and its companion, one that allows us an opportunity to explore a rare transitional phase in the… »

High probability of new eruptive activity at Chaparrastique volcano, El Salvador

In yesterday’s special report El Salvador’s Ministry of Environment and Natural Resources (MARN) said that the seismic vibration at Chaparrastique volcano (San Miguel) remains at very high levels, 20 times above the normal. The volcano continues to produce important gas emissions as well as occasional small ash explosions.These levels of seismic vibration and continuous emission are indicators that there is a high probability of another eruptive activity in the central crater or flanks. MARN said it should be mentioned that the geological process may last for months or even years.Seismic vibrations recorded at Chaparrastique during 2014.
