Nuke Expert: Fuel has “scattered all over the place” — Gov’t: Fuel may have burned out into environment
Nuke Expert: Fuel has “scattered all over the place” — Gov’t: Fuel may have burned out into environment
Reuters: Fukushima fuel melted through containment vessels and is “spewing radiation” — Nuke Expert: Fuel has “scattered all over the place” — Gov’t: Fuel may have burned out into environment — Tepco Official: Fuel could have flowed out “like lava in a volcano” (VIDEOS)
This is older about iodine but there a lot of cesium in Tokyo. There is probably iodine though it is hard to find new reports on it. I think the melted down cores are fissioning still and releasing abundant amounts of cesium into the underground river and sea. I think cesium from melted used, and other fuel rods melted from the catastrophe is dissolving and going into the underground river. All the tuna at Tokyo aquarium are dead. Many animals at Tokyo zoo dead.
This is a tremendous amount of rcesium found in and around forests of Tokyo and n japan.

ENE reports:
Reuters, Mar 11, 2016 (emphasis added): Today, the radiation at the Fukushima plant is still so powerfulit has proven impossible to get into its bowels to findand remove the extremely dangerous blobs of melted fuel rods, weighing hundreds of tonnes… The fuel rods melted through their containment vessels in the reactors, and no one knows exactly where they are now… Tepco has been developing robots [to] negotiate obstacles in damaged tunnels and piping to search for the melted fuel rods.
Reuters, Mar 9, 2016: Five years on, melted fuel rodsstill spew radiation…
DW, Mar 11, 2016: The melted nuclear fuel and the destroyed pressure vessel in the nuclear reactors 1 to 3 continue to be major problems… “So far, nobody knows what exactly happened in there and how to solve it,” [Heinz Smital, a nuclear physicist] told DW. “Until now, there is no solution to recover the melted fuel rods from the reactors.”
News Corp Australia, Mar 11, 2016: Today, the radiation at the Fukushima plant is still so powerful it isimpossible to extract and remove deadly melted fuel rods… [Tepco is] grappling with the fact that they don’t have the technology to find missing melted fuel rodsin three reactors at the plant. The rods melted through containment vessels in the reactors.
Guardian, Mar 11, 2016: [It’s] the most daunting task the nuclear industry has ever faced: removing hundreds of tons of melted fuel from the plant’s stricken reactors… something no nuclear operator has ever attempted… Of greatest concern, though, is reactor 1, where the fuel may have burned through the pressure vessel, fallen to the bottom of thecontainment vessel and into the concrete pedestal below – perhaps even outside it – according to a report by the International Research Institute for Nuclear Decommissioning… Masuda and Tepco engineers who spoke to the Guardian conceded that they still didn’t know where the fuel is located. “To be honest, we don’t know exactly where the fuel is”… Masuda said… “No one has ever done what we’re doing”…
PBS Newshour, Mar 11, 2016 (at 35:15 in):
- Miles O’Brien, PBS correspondent: What about the melted fuel in the reactor cores? They aren’t even sure where it all is.
- Lake Barrett, Tepco advisor: Is it in one big vertical lump on the floor underneath it? Or did it come down and flow like lava in a volcano and move out to the sides? We don’t know yet… Nothing of this magnitude [i.e. the attempt to remove Fukushima’s melted fuel] has ever been done by mankind…
Interview with nuclear engineer Hiroaki Koide(translation by Prof. Robert Stolz, transcription by Akiko Anson), published Mar 8, 2016: We simply do not know where the core is or in what state it is… [The government and TEPCO] are convinced that the melted core fell through the bottom of the pressure vessel and now lie at the bottom of the containment vessel―basically piling up like nuggets of the melted core [See Lake Barrett’s statement above]. There’s no way this would be the case. (Laughs)… It should have been scattered all over the place… Though the containment vessel is made of steel, if the melted core has come in contact with that steel, just as it ate through the floor of the pressure vessel, it could possibly have melted through the containment vessel… There are situations in which thecontainment vessel can suffer a melt-through. I think this likely has already happened.
