TEPCO planned for an earthquake, and a tsunami at Fukushima. Everything worked just fine, but the tsunami was much larger than predicted. The systems weren't designed to handle a tsunami that large, happening that quickly after the earthquake, and it flooded the pumps. The system went into automatic SCRAM at the first sign of the earthquake just as advertised. The fuel rods were inserted into the cooling tank to slow the reaction from taking place, just as advertised. The pumps were flooded too quickly after the tsunami broke the retaining wall that was in place around the plant, and that's what started everything off. Hydrogen built up quicker than expected, but when the workers returned to the plant it was still salvageable at that point, by venting the hydrogen. But when the pumps were turned on, to try to cool the cores, there was a spark which ignited the hydrogen.
So everything would have worked as advertised, if the tsunami had been of a size that was modeled when the plant was built.
Cooling restored at 2 Fukushima reactors Tokyo Electric Power Company says it has restored cooling systems for spent fuel pools at 2 of 3 reactors affected by a power failure at the damaged Fukushima Daiichi nuclear power plant.

Wow, people seriously need to learn to take sarcasm, and figure out what jokes are.
I have no intention of trying to kill threads, and I hardly enjoy it, so yeah, try again. And so sorry for posting a differing opinion than most people have when talking about Fukushima.

Actually we poop out most of the radiation we ingest. Most of it passes right through, some of it stays in for a while before being passed, and a small fraction stays in past our expiration date.

There are multiple sources for numbers, but just looking at the initial release, and not an over time picture, Chernobyl was still much worse. Over time, it might reverse, due to them not containing the reactors at Fukushima, but just talking about the initial release event, Chernobyl wins hands down.
Yes, there are a lot of things about the atomic bombs that are still classified, that make people wonder, and it's no surprise that cancer levels have increased in Hiroshima and Nagasaki, both through increased understanding of cancer as compared to pre-WWII, and due to elevated background levels.
Again, nuclear power is a necessary evil, that until we have something better, we have to live with.

'Most' of the fuel rods in pool 4 are spent rods. Reactor 4 was prepping for refueling, when the quake hit, and it's 'new rods' were in the cooling pool at that time. While the new rods have not been in service, which makes them 'more dangerous', they are the more dangerous of rods in the #4 pool.

And when I stop getting called out to prove that Chernobyl had a worse initial release, I'll stop bringing Chernobyl here.
