TOKYO (AFP) - New tests show almost all of the fuel inside one of the Fukushima plant's reactors has melted, its operator said Thursday, the latest step in the clean up after Japan's worst ever nuclear crisis.

Tokyo Electric Power Co. said the technology, which uses elementary particles called "muon" to create x-ray style images, gave the most concrete evidence yet the fuel had dropped to the bottom of the first reactor.

The data, though largely expected, should help Tepco as it continues its effort to decommission the plant four years after an earthquake and tsunami caused one of the worst nuclear meltdowns in living memory.

Engineers have not been able to develop a machine to directly see the exact location of the molten fuel, hampered by extremely high levels of radiation in and around the reactors.

JAPAN ADMITS; DAIICHI UNIT 1 CORE COMPLETELY MELTED DOWN

Evacuate Fukushima,

REACTOR CORE GONE AWOL ON UNIT1

福島第一原発１号機原子炉に、核燃料なし。
スッカラかん、スッカラあかん。

”No Nuclear Fuel Left, Fukushima Daiichi Reactor Unit 1.
Revealed by the remote sensing using a cosmic ray. ”

Let’s pretend this is fresh news and that no one would have thought that the core reactor of the Fukushima Daiichi Unit 1 had officially and entirely gone AWOL  *”absent without official leave” as I like to imply for this missing Corium

Actually, it took 4 years for authorities to relay such information to the public (us). It went from;  “no meltdown”, to “partially melt down”, to “melt down” and finally “completely melt down”.

Did they just say “complete melt down” ?

つまり、全部、キレイすっきり出てしまったということだ。
最大のテーマは、核燃料がどこにあるのか、どれだけ、原子炉の外に、
環境中に出てしまったのか。
事故の規模は、残存している、核燃料の量以外では測れない、
とさんざん言ってきました。
答えが、１号機については出ました。
「原子炉には、全く残っていない。すっからかん。全部出た」
ということが、４年かかって、やっと判明した。




Back in January 2015, TEPCO was introducing the use of the “muon” detectors for the imaging of cosmic rays coming from outer space as they pass matter like the concrete and steel of Fukushima and absorbed in high-density molecular materials like uranium in an effort to locate the destroyed radioactive reactor cores.  Muon imaging for Units 2 and 3 is still underway.

The x-ray like imagery indicates that the center portion of the bottom of the reactor pressure vessel appears to be missing and that the melted reactor core material has exited and relocated outside of the reactor vessel.

The exact location of the destroyed reactor cores for Fukushima Daiichi Unit 1, Unit 2 and 3 remain unknown.  TEPCO is attempting to probe beneath the wreckage for missing reactor core material with advanced robotics.

２０１１年秋頃のニュースで、１号機の格納容器の線量が極めて低いことが報道されたことがあった。（要確認）
推定ではあるが、格納容器は破れており（１、２、３号機、全て１億年に一回しか壊れない格納容器は、損壊している。）、全て環境中に漏出している可能性が高いのではないか。
方法論は、非破壊検査以外ないことはわかっていた。今回は、ミューオン（宇宙船の一種）でやったということだ。

It is more than likely, authorities at hand will have to re evaluate “one more time” the inventory of isotopes that spewed out of Daiichi (keep on spewing) since 311. We all know that Dr Yamashita and the rest of the clowns at the FMU had it wrong a few times and it is unlikely they will get it right anytime soon.



So while PM Shinzo Abe and the rest of the Nuclear Mafia keeps on telling the entire world that Fukushima is safe, I can’t stop shaking my head in disbelief, knowing that thousands of innocent souls are being rushed back to contaminated areas … not so far from 3 MISSING totally melted down reactor cores. Consequently this will also call for re assessing inventories of isotopes from Unit 2 and 3 as well.
