Video: Fukushima had “meltdown, melt-through, & melt-out within days of quake” — US Gov’t: Analysis says containment vessel fails after fuel melts through barrier — Experts: Corium may have melted out to reactor building, prepare for radiation doses over 200,000,000 microsieverts/hour
Science (AAAS), Mar 5, 2015: Fukushima Daiichi… won’t be truly safe until engineers can remove nuclear fuel… But first, they have to find that fuel… [TEPCO] thinks… fuel in the Unit 1… dropped to the bottom of the containment… engineers need much more detail about its location and condition… By the end of this month, Takasaki says, the detectors may have absorbed enough muons to confirm there is no fuel left in the reactor core… [Detectors]won’t be able to map fuel that may have flowed to the bottom of the containment vessel.Jiji Press, Mar 5, 2015 (emphasis added): Where is the melted fuel in the stricken reactors at Fukushima No. 1? This remains a question… cosmic rays [are being used] to “see through” the reactors… [Prof. Fumihiko Takasaki of the High Energy Accelerator Research Organization calls the] nuclear disaster a “national crisis”… muon detectors were… placed last July at reactor No. 1… As detector units can’t be placed underground at reactor 1, any melted fuel in the underground part of the reactor will go undetected.
Wall St Journal: Fuel rods… melted fully out of their pressure vessel [says Tepco]… but it likely stopped as Tepco began [injecting] seawater [See: Tepco: We should have told public this sooner… water injections failed to cool melted fuel]… Edwin Lyman, a senior scientist with the Union of Concerned Scientists, says it remains unclear why the fuel rods didn’t also breach the containment wall. “Why this didn’t happen is still unknown”…
U.S. NRC — State-of-the-Art Reactor Consequence Analyses (SOARCA) Report (pdf), Oct 2012: Fukushima Daiichi… presented… many insights with potential parallels to SOARCA’s analysis of… Peach Bottom, a similarly designed plant… in the SOARCA scenarios, significant hydrogen release [begins with] failure of the containment pressure boundary, which… results from molten debris failing the drywell liner… (i.e., drywell liner melt-through)… TEPCO has announced… the fuel did not move laterally across the drywell floor [and melt through the liner]… In the analyses presented in
this report, hydrogen [was] released via the failure of the drywell liner by melt-attack.
Argonne National Lab (USA), MCM (Switzerland), Sep 2014: location of 1F corium — Critical questions relate to the extent of core melt and the extent to which it has melted through RPV and penetrated into the primary containment… “hot particles”… may be throughout the reactor building [and] water collection system and even released to surroundings… Identification of hot particles… is going to be critical for safe decommissioning… [the equipment] must withstand extremely high radiation – perhaps up to greater than 200 Sv/hr.
More from MCM: Most molten core appears to be contained within the primary containment, although a very small extent of melt-through to… cannot be precluded.
Symposium sponsored by Consortium for Japan Relief — Chim Pom, published Feb 2015: “Media never reported that the whole process — meltdown, melt-through, and so-called melt-out — happened, was done within a few days after the earthquake.”

Muon imagery will be useless at Fukushima, because there is so little melted fuel above ground level.
“As [muon] detector units can’t be placed underground at reactor 1, any melted fuel in the underground part of the reactor will go undetected.”
Muon imagery is less than useless, because months have been lost relying on the muon imagery effort to map the missing cores.
Mapping the missing corium is Fukushima Job One.
Isolating the corium from the environment by diverting groundwater away from the corium is Job Two.
Where is the missing corium, eh, TEPCO?

Fourth Anniversary of the 3/11/2011 magnitude 9.0 Tohoku, Japan earthquake and nuclear disaster.
Happy 4th birthday, Fukushima!

At this time, I can find no mention of Fukushima Anniversary onhttp://www.cnn.com.
I also am tuned into CNN on TV.
No mention of Fukushima in the past one hour.
But I know all about the stupid Republicans and their stupid open letter to the leaders of Iran.
And Hiliary’s email.
Way to go, MSM. Completely missing the boat once again.

Today many folks will realize that TF2 is worse than they were led to believe, but most will shrug it off and resume posting inane tidbits about their recent weekend exploits to their FaceBook page.
I mean, like, this Fukushima Fiasco happened what 4 years ago? Why dwell on the past. Sure the tsunami was horrific and the evacuees can’t ever go home, but Japan is still kicking so move on ya Fukushima Fearmongers.
The Pacific? Oh, that’s just a warm water thing, the sardines are missing so the sea lions have less food.
Besides, my aching bones can’t be from strontium-90 could it? And my palpitating heart from cesium 134/137? My recent depression from melatonin/serotonin disrupted shared electrons in the indoleamine ring? Surely my leukemia and thyroid cancer happened because I ate at McDonald’s too much?

“”We had an explosion,” MIT’s Dr. Jim Walsh reports, the Boston, Massachusetts skyline and the Prudential Center skyscrapers glimmering brightly behind him. “It turned out that explosion did not compromise the [nuclear] core facility,” he guesses (minute 29). Walsh immediately betrays his speculation a few minutes later (minute 59). “Hopefully [emphasis added], it’s just the outer structure, and has left unaffected the reactor, and unaffected the containment vessel. Because if it were to affect those things…uh… that would be bad news…”

Great surrealistic photo bo!
As the Black Knight would say: “Just a scratch!”
And that was the reactor building that supposedly wasn’t even online 4 years ago on The Day Japan As We Knew It Died.
