    Fukushima Update: 50,000 trillion Becquerel’s of radiation leaked: 300 tons of radioactive water leaking daily into the Pacific no known technologie to fix it

    [​IMG]

    By National Nuclear Security Administration (NNSA) US Department of Energy
    The China syndrome refers to a scenario in which a molten nuclear reactor core could fission its way through its containment vessel, melt through the basement of the power plant and down into the earth. While a molten reactor core wouldn’t burn “all the way through to China” it could enter the soil and water table and cause huge contamination in the crops and drinking water around the power plant. It’s a nightmare scenario, the stuff of movies. And it is happening at Fukushima and there is no technology known to man to stop it continuing.
    TEPCO, Tokyo Electric Power Company however is trying to play down the full impact of this nuclear accident.
    According to scientist Micho Kaku there is a mathematical formula which can determine at what level the accident really is.
    Apparently the stricken nuclear plant has already released 50,000 trillion Becquerel’s of radiation which would put Fukushima in as a category 7 nuclear accident which is still less than Chernobyl however The Fukushima plant is still continuing to leak radiation from its reactors and TEPCO have claimed the problem could take another 40 years to fix, and to top that statistic the whole situation is less than stable.
    Fukushima is basically a ticking time bomb.
    [​IMG]
    The slightest disturbance i.e. a small earthquake and there are many as the stricken plant sits on a fault line causing a pipe to burst and an evacuation of the crew could set off a full scale melt down at all 3 nuclear power stations taking the catastrophe far and beyond what happened at Chernobyl.
    To make matters worse TEPCO in a moment of panic pumped in sea water from the Pacific in a desperate attempt to keep water above the melting core but as we well know sea water contains salt which corroded any remaining working pumps at the site.
    They resorted to sending in suicide squads into the crippled plant to hose water onto the melting reactor.
    And the situation has now worsened.
    This accident has released enormous amount of iodine into the atmosphere, Iodine is soluble, and when it rains it soaks into the soils and of course into the food system.
    Farmers there are now dumping milk and crops and the local economy has collapsed.
    It's been over half a decade since Japan's Fukushima Daiichi nuclear power station suffered a catastrophic meltdown which topped the International Nuclear Event Scale due to its severity. Radiation loves to hang around, and researchers conducting operations with robots inside the damaged reactors were met with radiation levels at their highest point since the actual meltdown back in 2011.
    In fact, the radiation level is so elevated that the robot operators had to quickly recall one of their robotic probes because it began to literally go blind.
    Like sending a rover to another planet, the mission for robot operators from the Tokyo Electric Power Company (TEPCO) is to monitor the status of the failed reactors and the nuclear materials housed within.
    [​IMG]
    Unfortunately, the radiation level of the reactor units was high enough to actually begin to damage one of the robots' camera systems, and could have completely blinded the view for the operator and left the bot stranded in the radioactive hellscape. (In layman's terms what they are saying here is no technology has yet been invented to fix the problem, humans or robots cannot get anywhere near the rector long enough to fix the problem so TEPO's claim it will take another 40 years to fix the problem is probably a very conservative guess)
    However, TEPCO was able to study some of the readings taken by the robots before things went awry.
    The scientists have estimated the level of radiation to be anywhere from 530 Sieverts per hour to 650 Sieverts per hour.
    Those numbers are representative of the amount of radiation an object would expect to be bombarded with over a specific period of time.
    To add a bit of scope to that, it's estimated that just one Sievert will cause fatal cancer in approximately 5% of people, while a dose of five Sieverts will kill 50% of people exposed to it within a month.
    As little as 90 millisieverts (0.09 Sieverts) accumulated over time can increase cancer risk in both adults and children. (With 300 tons of this stuff washing into the Pacific every day how long will it take before it kills the Pacific Ocean, it is a big ocean but not that big)

    Later this month TEPCO plans to send yet another probe into the reactor to take additional readings and hopefully paint a clearer picture of just what exactly is going on inside.

    So, why don't we just start sending inmates to Japan to clean up? I'm thinking if we take all of the life without parole inmates from lets say just the security council in the UN, that should be enough to get stuff unblocked and get the robots down to where they need to go.

    I think it is great you are thinking about this; and maybe that curiosity will encourage you to look into the subject. There are a few problems with your solution:

    The United Nations Security Council helps countries organize peacekeeping. They don't maintain prisons; they have no inmates.

    The Geneva Convention prohibits prisoners being worked to death.

    In Fukushima death would be quick. The reason robots are used is because human beings cannot withstand the levels of radiation discussed in this thread.

    :pileskulls:

    And then there are problems with the US sending inmates anywhere ... Japan doesn't want our inmates. Neither does anyone else. Neither do we for that matter. :bladewolf

    That only applies to POWs. The only civilian application of the GC that I know of is protection for people living in a war/conflict zone.

    That's not to say that arbitrarily killing run-of-the-mill prisoners isn't immoral. It just isn't addressed by the GC.

    Just to add, that level of radiation would also incapacitate humans immediately, so the labor wouldn't be of much use even without the copious moral issues involved.

    Hisashi Ouchi is a case study in that kind of exposure.

    Was it fate? If your name is 'Ouchi' are you destined for a horrible painful death?

    Oh, I know the UN doesn't have any control of prisoners, I just meant those countries. The US, the UK, Russia, China, France...

    Isn't tritium the stuff they stick in knives and doodads as a glow in the dark embellishment?

    A robot finally got pics of the damaged fuel rods.

    Bloomberg:
    Tokyo Electric Power Co. Holdings Inc., Japan’s biggest utility, released images on Saturday of mounds of black rock and sand-like substances at the bottom of the No. 3 reactor containment vessel at Fukushima, which is likely to contain melted fuel, according to Takahiro Kimoto, an official at the company. A survey on Friday found black icicles hanging from the above pressure vessel, which was “highly likely” to contain melted fuel. Kimoto noted it would take time to confirm whether this debris contains melted fuel.

    “The pictures that we have gained will assist us in devising a plan for removing the melted fuel,” Kimoto told reporters Saturday night in Tokyo. “Taking pictures of how debris scattered inside of the reactor was a big accomplishment.”

    Because of the high radioactivity levels inside the reactor, only specially designed robots can probe the unit. And the unprecedented nature of the Fukushima disaster means that Tepco, as the utility is known, is pinning its efforts on technology not yet invented to get the melted fuel out of the reactors.

    May take 40 years to fix if ,,,IF they can figure out how to clean and dispose of the waste which they can't figure out as of yet...

    Land-side Impermeable Wall (Frozen Soil Wall)

    It is actually a frozen soil wall around the four crippled reactor units, intended to block the flow of groundwater and prevent its mixing with contaminated water.

    The principal benefit of the frozen barrier compared with a physical barrier is that it avoids the challenges of building a wall around such underground obstacles as pipes, and creates a seamless barrier. Its effectiveness was demonstrated in tests held in March through April of 2014, when it maintained the ground temperature below 0 degrees Celsius.

    The barrier is being funded by the government, with construction being undertaken by Kajima Corporation, one of the few entities that has developed the necessary technology, which it has used at numerous construction sites, especially tunnels, to block water penetration. The refrigerant is environmentally safe and the chilled brine will flow through the pipes to a depth of 30 meters, freezing the surrounding soil and forming a barrier around the reactor facilities. The circumference of the wall is approximately 1500 meters.

    The wall is also designed to withstand even long-term interruptions of electricity, maintaining its effectiveness for approximately two months after the loss of power. It is one of several measures TEPCO is undertaking to reduce the amount of water that becomes contaminated on the site, thereby reducing storage needs and protecting the environment.

    Installation of facilities required for 'ICE WALL' Construction was completed on February 9, 2016.

    Activation was on March 31 of the same year.
    No firm timetable has been announced, but it is expected that the entire process will unfold over a period of months.

    Is this why they're saying a large amount of radioactive cooling water will soon be dumped into the Pacific Ocean?

    Doesn't really matter it's has been leaking in the pacific sense the the incident happen .I will not eat any fish from the Pacific .They been finding trace amounts of radioactivity in the plankton and some fish near the shores of the west coast int the past 3 years

    No. That water dump is a from a site that "includes hundreds of tanks containing about 777,000 tons of water laced with tritium that TEPCO has decided to dump into the nearby sea, despite opposition from local fishermen."

    So ,,, we're all going to be fluorescent at some point. Oh well. What's going to get us first, the coming pandemic, climate change, or our own congress? :shocked::hairpull:
