Take a look at pretty much any study calculating the probability of major nuclear accidents (aka "beyond-design-basis event").

The German TÜV performed such a calculation - funded by the government - in 1980 which was then used to argue FOR nuclear safety and expand Germany's nuclear reactors (as the oil crisis a couple years prior was reason to diversify away from oil). The study did not include human error/negligence or sabotage but all possible weather events (flooding, earthquake, lightning strikes into electric equipment), parts failing and an airplane strike.

The result: A reactor core meltdown occurs - in Germany - once every 10,000 years. Extrapolating this to 400 reactors worldwide - not sure how their safety compares to 1980's Germany - would result in one meltdown every 25 years.

Coincidentally Chornobyl and Fukushima just so happened to be 25 years apart. Substiture Chornobyl with Long Island if you want to exclude incompetent Soviet safety engineers.

The study:

Besides: Any money invested into nuclear today is money not invested into solar, wind turbines or battery storage. Why waste money on nuclear reactors that will start operating by 2040 when you can generate hundreds of TWh of electricity with the same money spent on renewables beforehand?

Wind and solar are great when there is wind and sun, but even with battery storage to even them out, there is always a flux. For example where i live in the last 30 there was 72 hour period when wind power worked only 1% of the max capacity and here is 3 month period when sun is over the horizon less than a hour per day and that time is when the energy consumption is on its highest.

Also climate change is bringing more high wind days when running wind turbines is impossible.

If we want to talk about natural disasters wind and solar power can be influenced by volcano eruptions happening thousands of kilometers away.

At the moment even hydropower is being effected by weather as there has not been enough rain to fill the reserves at the pace energy is needed.

Nuclear energy works no matter the weather and upping or lowering its production is relatively fast, making it really easy to adjust the output to the needed levels. Also the fact that from 100 spend uranium rods you can make 96 new ones

Im not against solar or wind. Im against putting all the eggs in to one basked and building a infrastructure that is dependant on things beyond human control.

I assume you mean three mile island reactor? Chernobyl was soviet fuckup, three mile island meltdown wrote a lot of new safety regulations and fukushima was natural disaster. Every one of these incidents has been studied and every one of them has made lot of new mechanism to avoid similiar accidents to happen in the future.

Are you in a Scandinavian country by any chance?

Because their entire economy is predicated on fossil fuels. That's a much bigger problem than reliable generation.

No??? Nuclear is by far the slowest to moderate. So slow, energy prices used to be significantly lower at night in Germany due to the nuclear power plants not being able to adjust to the lowered demand.

It is fairly obvious in the future energy consumption will adjust to the production, instead of vice versa like it is right now. I'm talking decades, the time to build maybe 1.5 - 2 sets of new nuclear reactors. That way you need at most hours of grid storage instead of days.

And about the scary "sun and wind is subject to variations" part - of course it is. Which is why it's best to also invest into significantly expand the European power grid to adjust. When there's a power drought somewhere it is very likely somewhere else produces more than enough energy to export. As an added benefit, this makes the grid much more resilient.

Centralized power generation is not a sensible thing to invest into in today's age anyway. Putin would merely have to send a double digit number of drones/rockets to cause blackouts. Compare that to a fully decentralized energy grid where for instance every house has solar panels and battery storage.

Also, not a single nuclear accident is preventable. Why was the Fukushima reactor not designed to handle its event? Because it's cheaper. Why did Chornobyl explode? Because it was a cheap reactor type. Three Mile Island (to be fair, that's pretty long)? Because again design failures due to cost cutting. And cost cutting refers to being able to humanly construct a nuclear reactor - if every scenario were considered no plant could be built. It's like trying to design a plane that will never ever crash - impossible.

Modern plants can change their power output 3-5% of their total capacity per minute, but they dont often do drastic adjustments like, because its more efficient to run them on the designed power output and it is something that is fully solvable with battery banks, because the output is steady. Unlike with solar and wind.

One of the Germanys stupidest decitions latelly was to shut down their nuclear plants. It made them use 7% more fossil fuels, it made them dependent on Russian natural gas and some calculations say they could have been producing 70% less of carbon emissions between 2002-2022 if kept running on nuclear.

The exact moment the pipe dream if decentralized energy grid gets any where near working condition ill change my mind. Until then nuclear is the best option.

Like i said. Im not against solar or wind. Im against coal and fossil fuels and we cant get rid of them quick enough if we are naive and wait for solar and wind to grow enough to replace those. Lets get rid of the real pollutors first and then start to replace nuclear with something else.

Dont start to fix the broken window before the fire on the roof is under control.

Substiture Chornobyl

shlarblegarble schnornobyl sure thing bud

Long Island

ai writing this shit for you? long fucking island? NY?

you mean 3 mile island, PA.

it's hard to take anything you write seriously when you don't understand basic geography.

I don't even disagree with you, mostly, we'd be better off going all in on renewable and storage, but some heavy industries - concrete production, smelting, heavy industrial processes, chemical manufacturing - all require a baseload that renewables struggle to provide while providing residential and business coverage. Having dedicated renewable generation solely for those loads might work with plentiful storage, but you'd have to over-buildout your generating network to handle both.

That said, I'd rather just continue with the nuclear we have - the enormous investments have been made already, keeping them running - and avoid SMRs and other silly shit. Nuclear + renewables would completely wipe obviate coal/oil.
