- Structure is built so that there is a six inch thick steel containment designed to contain any meltdown accident that could happen.
- Automated systems are in place that shut down the reactor at the first sign of trouble – ALL the reactors are shut down. That happened instantly with the earthquake. The problems are with their cooling post shut down. If the reactors were working, there sure wouldn’t have been problems with getting electricity 😀
- On the switching off of the reactor, the power supply is provided by generators. These generators have multiple redundancy. These were damaged by the extraordinary tsunami that followed the extraordinary quake.
- With all the generators knocked off, the cooling was taken up by an emergency battery backup. This lasted for 8 hours.
- With the battery exhausted, the cooling started using the steam from the cooling reactor itself. This got knocked off when the hydrogen from the venting exploded (and started a flood of “OMG nuclear blast” Tweets)
- With all this collapsed, the last ditch resort was flooding the reactor with the cold seawater laced with boric acid. This is also readily facilitated by the design of the reactor – like I said earlier redundancy, for redundancy, for redundancy to avoid a disaster. This destroys the reactor, but pretty much brings everything to a grinding halt. As long as they keep the place nice and flooded, everything should cool completely in a couple of days.
