The radiation near Chernobyl is insignificant compared to the damage CO2 can do. ...

Agreed, but beside the point we were coming from, which was that nuclear accidents leave behind problems for extremly long times. We were talking about the coffin that shields the hot radioactive garbage inside the Chernobyl reactor.
 
I did not imply we can "calculate" expected deaths.

Noted.

It is certain that there ARE more deaths.

It's probable that there are more deaths. We just don't know.

There is a continuum of radiation dosis from "we know that killed 50" to "so low it doesn't hurt".

More accurately, there is a threshold where radiation starts being dangerous.

This betrays an enormous bias in favor of nuclear power.

If you're going to argue from your emotional state, then this is going to get nowhere. You're miffed that I told you you had a bias, and now you're trying to satisfy yourself emotionally by throwing it back at me. Do you think this is the rational thing to do? Do you think this shows that you are being skeptical on this issue?

I'm talking about actual science, Oystein. Real science that tends to show that low levels of radiation are helpful because they stimulate the immune system, among other things. When you stop to think about it, rather than respond instinctively, it makes sense, because humans like other animals evolved in an environment with low levels of radiation.

Of course I do - and you make excuses to deny, or belittle, the high risk that more nuclear plants WILL go bust in the future.

Why are they excuses rather than facts? What basis do you have, given your displayed lack of knowledge on this topic, to dismiss my arguments as "excuses"?

Ignorance, huh? I wrote, and you quoted:
"Of course there are radiactive reactions going on at a dangerous level now, and for thousand years to come."
Please explain my ignorance by pointing out exactly what is wrong, or missing, with that statement?

First of all, the term "radioactive reaction" is nonsensical. And no, they're not going on "at a dangerous level now" or "for thousands of years to come", unless you are using an impractically low threshold for "danger". Thirdly, and as I've said repeatedly, there is a fundamental and very important difference between a chain fission reaction and normal radiation.

Of course there is nothing wrong, and nothing missing, with that statement. It is prefectly correct and complete.

You are in no position to evaluate your own statements, sir.

Still irrelevant, a strawman.

And now you don't even know what a strawman is!

No one debated what WOULD be the case in some Hypothetical.

Of course one did, since one has confused chain reactions and radiation. By claiming that the two are essentially the same, you are denying that one would be worse than the other. But since now you're backing away from this by saying that "no one (including yourself) debated" this, one gets the impression that you, somewhere along the way, realised that you were wrong, but are unwilling to admit it.

Regardless of what the nature of that radioactivity is.

This is an educational forum for skeptical discussions. If correcting people on egregious bad uses of terminology is unacceptable or silly, then what's the point?

Strip your rant of the strawmen, remove the eye patch from your skeptic eye, and try not to doublespeak, and you shall learn to avoid D-K yourself.
(See? I can do that personal attacking, too :))

Except that mine is based on observing your behaviour in this thread and yours is based on the fact that you're angry that I've called you ignorant.

See, I'm ignorant of all things knitting. If I were to participate in a thread about knitting and started commenting about stuff and then someone pointed out that I was confusing completely different types of weaves, would calling me ignorant on the topic be wrong? Would I be justified in lashing out and throwing it back to stroke my own ego, and then insisting that I wasn't wrong and that my statements were "prefectly correct and complete"?

And what the hell are you calling doublespeak anyway? Do you even know what that term means?

It is an extremely rare occurrence that a plane accident kills people on the ground.

It's an extremely rare occurance that a place crashes in the first place. That's why we haven't banned air travel. Because the risks are offset by the benefits and the commercial value of the business.

Nice way to avoid my philospophical question, though.

How have I ignored your question by addressing it?

There is a continuum of radiation dosis from "we know that killed 50" to "so low it doesn't hurt". Slightly below the "we know this killed Mr. Popovich" are high doses that people have been exposed to by the Chernobyl incident such that they died from them, e.g. by developing cancer, but we are not able to say who died of cancer by backgriund chance and who died because of Chernobyl.
I am not making any claims about what the number might be beyond your "50", but we do know for certain that it is >0.

A good book for you to read:
https://www.amazon.co.uk/Radiation-Reason-Impact-Science-Culture/dp/0956275613
This supports the idea that low level radiation is not harmful (and may be helpful at certain levels.

Your other posts seems to suggest that because nuclear power poses a non-zero risk, we shouldn't use it, even though it is safer than any other energy source we have, and we have climate change to tackle.

You mention that an increase in nuclear plants would increase the risk, but neglect to understand that risk. Let me give you an example:
Road deaths in the UK are lower now than they were in the 1950s. And yet the number of cars was about 3million (compared to about 30million today).

The point is that risk is not constant, but it changes depending upon what system we use, what technology we use. Things improve, and remember that the worst nuclear accident killed only a fraction of the number of people killed by fossil fuels every year.

So what would be the alternative? Well, you could use another energy source and watch a rise in energy related deaths, or you could stop using energy and watch deaths increase of the vulnerable due to a lowering of living standards and economic hardship.

Basically, the opposition to nuclear power is based upon fear, and nothing else.

Another thing renewables have currently going for them is the manpower required per MW: as a State, I want more people employed, so of course I would rather go with solar than coal or nuclear, given the option.
Benefits like these are often not taken into account when calculating death/terrawats, but if one technology can keep twice the number of people health insured, it might more than offset the fact that it is 15% more deadly to produce.
 
If we built the 50 000 or so reactors required to replace the energy currently supplied by fossil fuels they would consume the worlds uranium reserves in a little over a decade. If you want to replace fossil with nuclear commercial ready Fast Reactors and/or Thorium burning reactors are going to be required.

This suggests you don't understand how resource management works. With current uranium mines, this maybe true, but if nuclear capacity was greatly increased to a realistic level of what we need, then mining companies would start looking for far more resources, and almost certainly find them.

Added to this, we are sitting on huge quantities of spent fuel that can be reprocessed. Something that only a few countries use.

Then there are alternative sources such as sea water, and to a lesser extent: coal ash.

There is enough uranium in the oceans (and it has been demonstrated that it can be harvested economically) to last for thousands of years.
 
50 people died from Chernobyl.

How many have even heard of this:
https://en.wikipedia.org/wiki/Banqiao_Dam
The Banqiao Reservoir Dam (simplified Chinese: 板桥水库大坝; traditional Chinese: 板橋水庫大壩; pinyin: Bǎnqiáo Shuǐkù Dàbà) is a dam on the River Ru in Zhumadian City, Henan province, China. Its failure in 1975 caused more casualties than any other dam failure in history at an estimated 171,000 deaths and 11 million displaced.[1] The dam was subsequently rebuilt.

I do think the dangers of nuclear power are overhyped.
 
how much food did the dam help produce before it collapsed? How many floods did it prevent? How much excess nuclear power did it store in times of low grid load? How often, compared to a nuclear power plant of the same output, was it maintained and upgraded?
And did the collapse have anything to do with the fact that it was producing power, or would the same thing have happened if there hadn't been a single turbine installed?
Switzerland, Norway and many other countries have used hydroelectric with no significant issues for decades. Even the recent failure in the US, admittedly caused by poor maintenance, did not cause serious harm.

In short: comparing nuclear power with hydroelectric dams is not appropriate in my book. One is highly specialized, the other is incredibly versatile.

If your goal is the occupation of the idle, rather than the efficient and profitable use of resources, why not simply build a pyramid?

This signature is intended to irradiate people.

Solar is competitive with nuclear and coal, even with way higher labor costs - what does that tell you about resource efficiency and possibilities for future price reductions?
 
I wonder how much surface and iron/other materials we'd need to power the whole planet with solar, though.

It's a reasonable question for some of the hard-to-obtain materials.
The rest is a trifle.

Solar is still in the acceleration-phase in that the main concern is optimizing efficiency and not longevity: why make a panel that will last 10 years if a better one is available in two?
This creates waste, some of it quite bad: solar might have no running CO2-footprint, but it has an initial one.

Yes, but that’s only applicable to comparing Wind/Solar to Nuclear. The duration of the damage from CO2 could greatly exceed this. It’s also worth noting that while the area around Chernobyl is unfit for human activity, ecologically it seems to be doing better with the radiation than it was with the humans.

In spite of the down sides of Nuclear it’s still nearly always better than Coal/Gas/Oil fired generating capacity. Talking about it's downside is fine as long as that is kept in mind

Well, I hope you're right. I may be a proponent of nuclear, but if a better alternative comes along there's no reason not to go for it. Question is: will solar be that alternative soon enough, or do we need a intermediate replacement for coal?
 
There is enough uranium in the oceans (and it has been demonstrated that it can be harvested economically) to last for thousands of years.

Why stop there, why not include all the Uranium in the asteroid belt? Commercial availability is about the same at this point.

In fact, there's a kind of fungus growing on the walls of the reactor, feeding on gamma radiation. That's pretty awesome (but irrelevant to the discussion).
