I'm a nuclear power advocate. I am on social media making arguments in support of massive expansions of nuclear power to reduce air pollution and fight climate change. I have a Ph.D. in nuclear engineering and a professional engineering license in my state. I chose nuclear engineering at age 19 because I wanted to fight climate change, not because I wanted to become an industry lobbyist. There are hundreds of nuclear advocates just like me.

While nuclear power is commonly perceived as unduly dangerous, if you're interested in the numbers of it all in context, I highly recommend this page:

https://ourworldindata.org/safest-sources-of-energy

The whole wasteland argument falls apart quickly when you take a look at e.g. a worst case scenario like Chernobyl and compare it to the fact that fossil and biofuel cause 7 million premature deaths per year from particulate emissions (according to the WHO) and cause global climate change.

How many of the safety assessments take into account the fact that the nuclear waste is almost never buried away and in a dispersed matter and instead it's kept near the nuclear power plant in dry/wet pools because of NIMBY?

This has the effect turning the nuclear power plant into a giant dirty bomb. Almost all the problems at Fukushima were caused exactly by these used fuel pools, and not by the nuclear material in the plant itself.

And then you have Ukraine where dry storage is shelled with artillery.

This phenomenon cuts both ways. Ralph Nader in the 70s kept telling falsehoods about the health hazards of nuclear power, seemed immune to correction, and had a platform with the press uncritically propagating his claims. (Documented in Petr Beckmann's book at that time.) In retrospect this seems like a hinge point in history leading to our current energy problems.

Someone's incentive towards some point of view is not evidence either way about an object-level claim. It's only useful for questions like attention allocation, or like how someone could be so wrong after you've established they're probably wrong.

Counterargument: I am readily employable in other related industries and could likely get a significant raise switching. Every time I make an offer to a software engineer who asks for >$50k more than our peak salary, I'm reminded of this fact.

Again, I chose nuclear specifically to fight climate change, not to make the most money.

I chose to be a software developer because I was interested in creating things, but now I am just a cog in a machine trying to generate income. I don't doubt your motives, but what is the situation we are currently in?

Nuclear has failed to make a dent in emissions for 60 years now. Whatever the reason might be, rationally it's time to at least ask "can it ever make an impact"? But this question is almost never asked. I honestly believe there is a symbiotic relationship between nuclear and fossil fuel industry. Nuclear cannot survive without the threat of fossil fuels, but it cannot or at least has not for decades prevented fossil fuels dominating electricity production worldwide. So it's a guarantee for keeping the status quo. It's time for something else. Not merely another technology, but another way of thinking.

Re:Nuclear power plant leaked 1.5M litres of radioactive wat... by belorn on Saturday March 18, 2023 @07:36PM (#35214328)
I remember seeing that question for quite a long time, and the answer was that as long there is cheap access to fossil fuels and the population do not vote for carbon taxes and similar policies, then the answer is no. We will never see alternative technologies unless they can beat fossil fuel on price alone.

The bet that the previous governments in EU made the last decades was to switch generation to wind and solar when weather condition makes it cheaper than natural gas, and then use natural gas (primarily bought from Russia) for everything else. When green hydrogen become cheaper than natural gas (estimated 2050-2080) we can start replace that natural gas with hydrogen. The big event that changed that was the invasion of Ukraine and the climbing prices of natural gas.

The other way of thinking would be to consider other aspect than price. Those could be geopolitical, global warming, or pollution. I am however doubtful, and the events in EU this winter demonstrated how much citizen demanded government subsidizes and intervention when prices of energy went up. Energy prices are also tied to economic stability and growth, which makes changing the way people think difficult.

The reason is because it's been denied a chance by government regulation, due to a mixture of fossil fuel lobbyists and people's irrational fears stoked by propaganda designed to make it seem scary.

The answer to "can it ever make an impact" is yes, it can, using existing technology, right now. We just have to get rid of the regulations designed to destroy it.

>a worst case scenario like Chernobyl

Chernobyl was not a worst-case scenario, it is just the worst scenario that has happened so far. If it hadn't been handled by humans sacrificing their lives to stop the chain of events, it could have been much, much worse. Had the fire continued it could indeed have been a "wasteland" scenario.

The site you recommend makes claims about safety that are logically broken. Things are not safe based on what has happened so far, they are safe or unsafe based on what could happen in the future. Surely you realize this.

The claim this site makes is equivalent to saying that a gun is safe if it hasn't been used yet. I frankly find it to be a very dishonest argument, it seems designed to mislead rather than enlighten.

Re:Nuclear power plant leaked 1.5M litres of radioactive wat... by acidburnNSA on Saturday March 18, 2023 @06:47PM (#35213963)
The fact that it was:

a) an unstable reactor

b) without a containment structure

c) that was put through a dangerous experiment overriding safety systems

means to me that it's very likely to be the worst commercial nuclear power scenario we'll see.

Compare with Fukushima where a whole area was inundated by a tsunami and a triple meltdown, leading to very few, if any, people receiving more than the minimum dose known to cause measurable harm.

And again keep in mind that we're comparing against fossil and biofuel, which power over 80% of the planet and cause 7 million premature deaths from particulate emissions every single year just operating normally.

I guess the term 'worst case scenario' isn't really useful since there's always someone who can come up with something else, regardless of how unlikely it is. Fair point on that.

Now try get private insurance for a nuclear power plant.

The alternative is not burning things, it is renewables. Stop creating a strawman to argue against.

Try to get private insurance against climate change and air pollution and blackouts.

Fossil and biofuel make 80% of our energy. This is not a straw man argument.

Re:Nuclear power plant leaked 1.5M litres of radioactive wat... by Gwypaas on Saturday March 18, 2023 @07:26PM (#35214272)
Moving the goalposts...

Primary energy. That will shift dramatically as industries get electrified. No point cooling 70% of the produced energy in a nuclear or coal plant anymore.

Similarly, the question of interest is what to build. Fossil, or nuclear plants barely exist on that list globally.

It is simply too expensive. 5x the CO2 emissions get displaced by building renewables compared to nuclear, with a much shorter time to value.

Investing in nuclear today prolongs the climate crisis.

> Investing in nuclear today prolongs the climate crisis.

This kind of willfully blind thinking continues our reliance on fossil fuels. There is a need for reliable energy that cannot yet be met by renewable energy. For this specific reason, Russia funded German opposition to nuclear power.

Let's fix the +90% that is trivial without storage and work on the last percents when we get there in the 2030s.

The research finds it easily solvable today, but a holistic approach is necessary.

"Easily solvable" is highly dubious. The guy behind the 100% renewables no nuclear allowed push sued his scientific critics for publishing a critique of his work and was eventually forced to pay their legal fees. [1]

But that aside, just looking at the sheer magnitude of capacity mentioned in his papers, one can see that it's not even remotely easy or trivial. See eye-watering Table 2 in [2]

Nope, I am pointing out that 100% renewables is far harder than claimed, that criticism has been suppressed, and providing refs to back up my points.

I'm pro anything low carbon. I love wind and solar and hydro and nuclear. These no-nuclear people are trying to get us to tie a hand behind our backs for no reason in the midst of a climate crisis. Energy generation choices are not a zero sum game.

Lots of antinuclear people mistakenly believe that pro-nuclear people are also anti-wind or anti-solar when in fact we are usually just anti-fossil and biofuel.

Re:Nuclear power plant leaked 1.5M litres of radioactive wat... by Gwypaas on Sunday March 19, 2023 @11:35AM (#35220011)
We can agree that 90% is trivially solvable. That will get deployed shortly.

So you are telling me that a peaking nuclear plant will solve the last 10% when it comes online at earliest 2040? What problem are we even solving then rather than brute forcing nuclear into the solution?

Then try put that nuclear power plant on a marginal price market. What do you expect to happen?

Re:Nuclear power plant leaked 1.5M litres of radioactive wat... by Kon5ole on Saturday March 18, 2023 @08:37PM (#35214724)
In my opinion the interesting point is c).

Simply put, humans failed and caused a catastrophe. If you have c), a) and b) don't matter. And we will always have c).

Humans are currently failing by waging a war around nuclear power plants. How safe those plants are under normal operation doesn't really matter. Humans fail by performing terrorist attacks too. They fail by building nuclear plants that can't handle a tsunami in a tsunami-prone area.

Nuclear power provides centuries of opportunity for humans to fail in ways that have immense damage potential. This is clearly a very real risk, and makes nuclear power unsafe.

One can still argue for nuclear power, but not by saying it's safe. It simply isn't.

That isn't the issue, which is solely economics. Don't waste your time advocating and persuading. Bring the power of your nuclear engineering Ph.D. to bear towards making nuclear power profitable. There is nothing else is stopping nuclear power other than the economics. It's a deal-breaker. But make it profitable, and there is nothing on this Earth that could stop the proliferation of nuclear power plants. They'd literally be everywhere.

Nuclear: there are many ways to estimate the amount of victims (long-term, all ailments...), leading to a huge interval of values.

"Fossil fuel or nuclear" is obsolete since renewables became pertinent. Moreover our current capacity to deploy useful nuclear reactors isn't convincing.
