Fukushima was an unsafe design. Chernobyl was both an unsafe design and being operated in an obviously risky and neglegent way when it failed. These kinds of disasters won't happen with more modern reactors that already exist. Even if they do, making a few permanent wildlife reserves in the irradiated areas isn't a global catastrophe. The world is full of uninhabited and uninhabitable places.

> Fukushima was an unsafe design

Fukushima was a standard design. Built by European and US companies in the same style as dozens of plants in Germany.

This is not "Fukushima was unsafe". If you say "Fukushima was unsafe", then half of Germany’s reactors are unsafe.

Shutting them down was the only option.

> making a few permanent wildlife reserves in the irradiated areas isn't a global catastrophe

You are talking about Japan. A country with one of the highest population densities worldwide. Declaring a whole province – and one with lots of history – off-limits is not going to happen. Currently they’ve been digging out the ground in half of the province.

EDIT: Some more info:

Fukushima was a Boiling Water Generator built by General Electrics. Reactors of the exact same design are Krümmel (Germany), Brunsbüttel (Germany), Philippsburg (Germany), Isar (Germany). Krümmel and Brunsbüttel had constant issues, including the town next to it having the highest cancer rate on the planet.

The same design used by Fukushima is described in Wikipedia as "the second most common type of electricity-generating nuclear reactor".

The design was unsafe. The company knew this. In fact it had been known for 35 years. It was not unfixably unsafe, and in fact 5 of the 10 reactors had been upgraded. These 5 shut down properly during the Tsunami and survived without problems.

The main design flaw was that the vital emergency cooling equipment was sited in an unprotected building outside the protected reactor. This is especially troubling if you site your reactor on a Tsunami-ridden coast. It's less of a problem in the middle of Germany, where there are no Tsunamis. Or to put it another way: if you have a Tsunami reaching the middle of Germany, a meltdown at these powerplants is going to be among the least of your problems.

1960s design, things have improved.

Of course, it is hard to demonstrate improvements, especially when nuclear power is so demonized.

[sillygeese]

Well the way for a reactor to "demonstrate an improvement" over Fukushima would be to withstand the same kind of earthquake + tsunami that Fukushima didn't.

It doesn't make sense to say it's hard to demonstrate improvements when it's not even under our control.

But demonizing nuclear power has nothing to do with it.

Gee, what a great idea! In fact, a slightly improved reactor was operating in the other Fukushima plant, and all its reactors were shut down safely after being hit by the same Tsunami.

More modern designs are safer still. For example, there are designs that do not require external power for a shutdown at all.

[kuschku]

Yes, modern designs are safer – but the first lesson to be learnt from Fukushima should be to take the older designs from the grid.

[DasIch]

I'm sure that the people behind Chernobyl and Fukushima were no less convinced that the design was safe and operated perfectly fine, than you are convinced that modern reactors are safely designed and operated correctly.
