Tepco detects increase in temperature in ice wall in Fukushima

Tokyo Electric Power : Plant operator detects increase in temperature in ice wall in Fukushima

Tokyo, Sept 2 (EFE).- Tepco Electric Power, or TEPCO, the owner of the Fukushima nuclear plant has detected an increase in the temperature of some parts of the underground ice wall that could affect its further construction and the dismantling of the plant.

The temperature rise was caused by intense rainfall in the region where the plant is located due to the typhoons that have been affecting the area since mid-August, a spokesperson of the company told EFE Friday.

The temperature of the wall to the south of reactor No.4 has gone up from minus 5 degrees to 1.8 degrees, according to the measurements carried out by TEPCO on Thursday.

An increase in temperature from minus 1.5 degrees to 1.4 degrees has also been detected east of reactor No.3.

The company is injecting a chemical in both the walls to solidify them, reduce the flow of water and accelerate the freezing process and is discussing other options in case these measures prove ineffective, the spokesperson explained.

Temperatures in these sections are already higher than those in other parts of the ice wall before the storms. However, there are fears some sections of the wall could have thawed with the increase in underground water flow due to the rains.

The company said that this incident could affect the deadlines for the completion of the wall but the construction, which entered the second and second last phase in early June, will continue.

The purpose of the wall is to isolate the ground around the four reactors – affected by the 2011 earthquake and tsunami – to prevent water from natural aquifers flowing into them and coming into contact with the radioactive refrigerant and the contaminated water then finding its way into the Pacific Ocean.

This setback increases pressure on the company, that had barely made progress in bringing down the water still within the reactor basements and had said in July that the ice wall will not be 100 percent effective in blocking the groundwater, thus complicating efforts to dismantle the plant.

How the viewing public was ‘protected’ from seeing what the Hiroshima and Nagasaki nuclear bombing did to people

Hiroshima and Nagasaki on the cutting room floor https://thebulletin.org/2019/08/hiroshima-and-nagasaki-on-the-cutting-room-floor/ By Thomas Gaulkin, August 5, 2019 Seventy-four years after nuclear weapons were first and last used in war, it can be challenging to conceive of the devastation they cause. But even in the immediate months after the atomic bombs were dropped on Hiroshima and Nagasaki in August 1945, news accounts offered a view of ingenuity and destruction that often elided the human cost.

The newsreels below [on original] were mainly screened to audiences in 1946 and 1947 and detail the destructive force of the explosions almost entirely through excited accounts of the structural damage to the cities. There’s occasional mention of the lost city populations and the scientific knowledge to be gained from studying their casualties, but hardly any description of what people actually suffered, let alone personal accounts. It’s instructive to look at and listen to these reports today, and contemplate what is missing.

The 12-minute reel below was produced by the US War Department in 1946. “Tale of Two Cities” makes selective use of film that was confiscated from a Japanese filmmaker, Akira Iwasaki—though you wouldn’t know that from the narration, which boasts that “army cameramen have found and filmed pictorial evidence that tells in twisted steel and stone the effect of death-dealing atomic power.” (Some twenty years later, historian Eric Barnouw obtained more of Iwasaki’s footage and produced a remarkably different narrative that documented the horrible physical impact of the attacks on Hiroshima’s citizens.)

Contrasted with the triumphant tone of the news/propaganda made for 1940s audiences, silence changes everything. Made public only decades later, the two films below —one beginning with footage of wounded victims, the other, a full-color glimpse of survivors picking up the pieces of the ruined city—report what those above do not, without a single word.
