Preventing another explosion at Fukushima has been key to the success of the narrative that the plant is "under control" and that radiation releases are "small."
There are many reasons this narrative is false.
First, radiation releases at the plant have not been small, despite public pronouncements. Please see my post here for details http://majiasblog.blogspot.com/2011/09/more-propaganda-sep-23.html
Second, the plant is not under control and there is very strong evidence that the cores of at least 1 reactor and maybe more have melted through all containment and are now fissioning under ground.
Third, the absence of an explosion does not equate with a stable or even, necessarily with a less-hazardous radiation environment. Radiation is being released daily and the tent being built at the plant will loft that radiation higher, which will help plant workers but likely increase jet stream contamination.
These reasons demonstrate the fraud at the heart of the narrative that no explosion means everything is under control.
However, we are creatures of conditioning and we tend to believe that all is fine so long as everything looks relatively normal. The normalcy bias is presently quite strong because we cannot "see" radiation and because its effects take years to be detected.
Tepco has done everything it can to ensure that their narrative of normalcy and control survives. Nitrogen was injected into unit 3 over the summer to prevent another hydrogen explosion. So far that move was (and perhaps continues to be) successful.
Tepco must be very worried about the hydrogen now accumulating in reactor #1, as reported by Enenews http://enenews.com/asahi-explosive-hydrogen-may-be-coming-from-melted-fuel-rods-and-accumulating-near-the-top-of-the-containment-vessel-without-being-driven-out
Enenews was reporting on a story published by Asahi: Hydrogen accumulates in pipes at Fukushima's No. 1 reactor
Asahi reports: "Hydrogen has accumulated to a level higher than previously thought in pipes connected to the No. 1 reactor containment vessel at the Fukushima No. 1 nuclear power plant, the plant's operator said Sept. 23...
"An explosion can occur in a gas containing more than 4 percent hydrogen and more than 5 percent oxygen....
"TEPCO has been pumping nitrogen into the No. 1, No. 2 and No. 3 reactor containment vessels to drive out hydrogen from their interiors. The injection of nitrogen is also intended to create higher pressure levels than those outside to prevent oxygen in the air from entering the containment vessels.'.." http://ajw.asahi.com/article/0311disaster/fukushima/AJ2011092411943
Majia here: The possibility of another explosion must make Tepco and governments all over the northern hemisphere quake because an explosion will reveal--disclose--the fraud that has been foisted upon the global public.
The fraud is the lie that all is controlled at Fukushima and that releases are "small."
Ok so my guess is that another explosion will not occur so long as it is humanly possible to prevent one because too many careers and too much corporate money are at stake.
Yet, the public needs to be awakened. The public needs to discard their normalcy blinders. Although the radiation released will not kill most of its victims quickly (those outside of Japan), Fukushima radiation will bio-accumulate and slowly kill and maim across generations, just like Chernobyl did and continues to do.
And unlike Chernobyl, Fukushima has been releasing large amounts of radiation for months, unchecked by containment.
