“But as far as Fukushima goes, the only thing that matters now is if world leaders and experts join forces to help fix this situation. Regardless of what agendas they are trying to protect or hide, how much it will cost, the effect on Japan or the world’s economy, or what political chains this will yank.The nuclear industry needs to come clean. If this leads to every reactor in the world being shut down, so be it. If the world governments truly care about their people and this planet, this is what needs to be done.”
This has been debated and true since day 1.
1. The world was ready to send help. Japan declined and lied about the seriousness of the situation.
2. The USS Ronald Reagan went past to assess, and immediately bugged out. Now crew members are suing Japan for radiation poisoning.
3. They still need international help. And TEPCO should be sued, all and sundry.
Arnie Gunderson, a veteran US nuclear engineer and director of Fairewinds Energy Education, told Reuters that “they are going to have difficulty in removing a significant number of the rods,” especially given their close proximity to each other, which risks breakage and the release of radiation.
Gundersen told Reuters of an incredibly dangerous “criticality” that would result if a chain reaction takes place at any point, if the rods break or even so much as collide with each other in the wrong way. The resulting radiation is too great for the cooling pool to absorb – it simply has not been designed to do so.
Toshio Kimura, a former TEPCO technician, told Reuters that the operation would normally be assisted by computers, but that luxury is gone. “Previously it was a computer-controlled process that memorized the exact locations of the rods down to the millimeter and now they don’t have that. It has to be done manually so there is a high risk that they will drop and break one of the fuel rods,” he said.
1. Remember that the Zirconium to shield the rods in the canisters has already broken, as we had explosions and then fires. To normally remove the casks, they would use remote controlled cranes and it would be in the contained buildings. None-of this exists now.
2. The rods and assemblies (holding amounts of rods), would be in 100% condition and removed with as much precision as possible, this is not the case now.
3. There is debris all over the spent fuel pool which could rupture any remaining rods and casks, leading to the release of Pu, U and many other exotic nuclides that are not meant to see anything bar lead and concrete at the very least.
4. A breach again of the zirconium shielding, and or lack of water, will create another fire and recriticality, that cannot be put out.
He is also expecting many issues for TEPCO ahead, as the process is estimated to take years. The scientists’ task is not made easier by the fact that the building is also prone to corrosion from salt water.
1. Corrosion is now very visible from photos, due to sea water having to be injected. This limits their time to respond by X
