Why I am not worried about Japan's nuclear reactors. | Morgsatlarge - blogorific.
The seawater will then be replaced over time with the "normal" cooling water The reactor core will then be dismantled and transported to a processing facility, just like during a regular fuel change. Fuel rods and the entire plant will be checked for potential damage. This will take about 4-5 years. The safety systems on all Japanese plants will be upgraded to withstand a 9.0 earthquake and tsunami (or worse)
Well, 4-5 years check; but I wonder if corrosion from seawater and damage from overpressure might not call for the replacement of main parts.
One whose delusions are out of fashion.

The big problem isn't the boric acid -- though it is an acid, and it can increase corrosion. The big problem is the chlorides in seawater. They'll need to be cleaned out before the reactor is safe to use again, and given the age of the Fukushima #1 reactors, it probably won't be worth doing so
I have little doubt that everything made of steel in those facilities will sit around for some years to 'cool'; then will be cut up for scrap - although the 'hottest' material may be buried.
I can hardly wait to read the articles about how Honda is going to send their walking robot into the plant to dismantle the reactor core, "just like during a regular fuel change." As if during regular fuel changes you have to deal with melted fuel rods...
Uniquely in engineering, it's a technology that wilfully ignores Murphy, while pretending to itself and everyone that it has Murphy covered.
This isn't a problem for renewables. The worst that can happen is that a mega-storm takes out your entire windfarm. You lose capacity, but you don't get millions of casualties.
With nukes, the worst that can happen is that hundreds of square miles of prime territory become uninhabitable. Is it even possible to put a number on that risk?

And this is pretty much shear luck:
If a pro nuke whore had been governor, things would be different. But, maybe there would have been a different target for the 9-11 air-jackings:
