The worst nuclear accidents that could possibly happen have already happened. We couldn't have a worse nuclear power disaster than Lake Karachay even if we tried on purpose. And yet the sum damage they caused is a negligible blip compared to how many people die due to the use of fossil fuels on any given month of any given year.

The environmental impact of nuclear power vs. fossil fuels or even renewables is just a negligible number no matter how you spin it.

I too am confused like the GP poster as to how otherwise intelligent people just break down into baseless fearmongering about imaginary disaster scenarios while ignoring that today's conventional energy industry is literally thousands of times worse.

If every single operational nuclear power plant had a meltdown incident after operating for 20 years, they'd still be orders of magnitude less damaging than what we're doing today. The environmental impact and safety numbers are just that far apart.

How can you write such a ridiculous sentence? We have nuclear power plants in the middle of inhabited areas with tens of millions of people who would be immediately affected by an explosion. It's a permanent subject of dispute here in Europe.

One single accident in Europe would dwarf these inflated WHO numbers.

Cite please. The tens of millions affected by a feasible powerplant issue. Explosion is not really in the realm of feasible unless we're talking about bombs or uncontained soviet reactors.

I'm sure you will be able to look up the location of active nuclear power plants in central Europe and determine the population figures within the range of impact of an accident like Chernobyl's if you try. Start with Mohovce (largely uncontained and litigation since 2005 or so), Bohunice, Temelin and the large cities nearby...

Why would we leave out terrorist attacks? Because they destroy your argument?

[kuzehanka]

What would a terrorist do with a nuclear powerplant exactly? We've flown fighter jets into nuclear powerplants to test them[1]. They're protected by armed guards. The US has a nuclear emergency task force ready to fly pumps and generators to any plant. The best attack even a highly resourced terrorist could mount would be to damage the cooling tower and not really make any difference?

If you're imagining some kind of super coordinated military unit taking control of a powerplant yeah sure maybe? They'd be much better used just poisoning the water supply.

This is exactly the kind of baseless fear driven hypothetical sentiment that I'd like to understand.

They can make "dirty bomb". I know some people which had training about how to destroy hostile Western country by using their own radioactive materials.

For example, in 2014, rebels in Donetsk had attempt to create "dirty bomb" using radioactive waste from abandoned chemical plant. Fortunately, they were spotted and stopped.

A bit off-topic (but still nuclear-related): All that adds big cost to nuclear and makes it less feasible

[wtallis]

On what basis are you determining that armed guards are a big cost? It's certainly a readily identifiable cost that's larger on a per-power plant basis for nuclear than other forms of power, but is it really large enough to matter to the overall economic viability of nuclear power?

[wtallis]

A bomb powerful enough to breach reactor containment but small enough to be smuggled past power plant security is already a nuclear bomb in its own right, and would be more effective used against population centers directly.

Explosion as in a nuclear one? Really isn't possible. The fissile material isn't pure enough.

I believe graphite rods are used as the safety to capture the neutrons in a nuclear fission reactor and effectively kill off the reaction.

Explosion as in Chernobyl level? That was basically water pressure.

[pfdietz]

Chernobyl had two explosions, a few seconds apart. The second, larger one was after most of the water had left the core. The reactor had a positive void coefficient, so losing water increased reactivity.

Of course these were prompt supercritical reactions in a moderated system, so they are not explosions in the sense of bombs, which are fast systems with neutron doubling times measured in fractions of a microsecond.

[lispm]

far from it. If nuclear fallout had been reached Tokyo, then we would talk about a much greater problem.

[ElBarto]

An accident in a nuclear plant that was constructed in a highly seismic and tsunami-prone area isn't an argument against nuclear power.

I'm sure that Germany can find a more suited location if they wanted...

Anyway, France is peppered with nuclear plants and Germany is right downwind from many of them.

That's why we would like to see some of them being closed immediately.
