So it’s 4 years on now from the Fukushima disaster. What do we know?
Well we know a little bit more about the extent of the damage. There are 6 reactors at Fukushima Daichi only 3 of which were in operation at the time, but all of which are involved. You don’t hear much about reactors 5 and 6 which were off line, but the reason they were off line is they were experiencing cooling problems. They sit today fueled, hot, closely monitored but unapproachable due to the high levels of radiation, slated for decommissioning.
Unit 4 was in a similar stand down. What makes it unique is that it still experienced massive damage from a hydrogen explosion and the bulk of its nuclear fuel was stored in a pool on it’s roof.
The good news is that all 1533 fuel rods have been removed as of just this last December, the bad news is that the ground is subsiding underneath it and the building is in danger of collapse. Even without the fuel the structure is still highly radioactive in operating areas and thoroughly contaminated by fallout.
All of the active reactors, 1, 2, and 3 experienced both hydrogen explosions and core meltdowns which almost certainly in the case of Unit 1 and probably in all of them has breached every level of containment and is sitting partially buried in plain old soil.
The salt water used as an emergency measure during the early stages of the disaster has corroded and ruined almost every installed control system and massive amounts of water continue to be pumped to this day to contain the reaction. This highly radioactive water is stored in big steel tanks (think Power Plant size) that are starting to rust and leak. There is no plan for how to dispose of it.
Speaking of radioactive water, it leaks out of the big holes in the bottom of the reactor containment units into the ground and natural ground water continues to flow through the site to the sea in a large and permanent plume. All efforts, including the much vaunted ‘ice dam’ created by freezing the dirt around the site have been an utter failure.
There doesn’t seem to be a Plan B.
Speaking of radiation, in most critical areas it remains high enough that even specially hardened electronics fail within hours, humans would die in days from exposure. Even in outlying areas of the 30 km exclusion zone workers can receive a lifetime dose in weeks or months. Thyroid cancer (an early indicator) has risen from 2 – 7 cases in a population of 100,000 to over 100 reported in a population of 300,000 so far.
Does that seem gloomy enough?
TEPCO (a zombie company, effectively bankrupt) and the Japanese Government continue to delay, obsfuscate, and minimize the impact of this event. Independent science is actively discouraged in favor of happy fun time propoganda. The Japanese Government, which is paying Billions for fossil fuels to maintain energy capacity, is actively pushing for the resumption of nuclear power production and the re-activation of the remaining 40+ plants despite the fact that they are no safer than they ever were.
In the mean time Solar is getting cheaper and better than ever to the point where it is price competitive with Oil even at $50 a Barrel.
Remember, it’s safe, clean, AND makes you glow in the dark so it’s easy to find your way to the bathroom at night!
The law that entropy always increases holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell’s equations – then so much the worse for Maxwell’s equations. If it is found to be contradicted by observation – well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation.
