Chernobyl was a 50 year old design, and happened 40 years ago, involved multiple human errors ... nah can't consider things have changed since then.

Things have indeed changed, now construction regulations are far tighter. This is good because the risk of a Chernobyl event is far lower, but at the price of extreme cost overruns and project delays

Ignoring the fact that coal and natural gas still hurt and kill people daily

So is it better to start a nuclear project and hope it can start reducing coal & NG emissions 10 years from now? Or is it better to add solar and wind capacity constantly and at a fraction of the price per MWh?

There was a time when nuclear was the right choice, but now it is just not cost effective nor can it be brought online fast enough to make a dent in our problems

Somehow Dams that would be devistating to destroy are given a pass, but hey Nuclear power, so scary.

I think you're forgetting that once the waters from a dam break dry up you can rebuild....a nuclear accident has the potential to poison the land for generations

And in ten years.. it'll be too long to add nuclear ... And in ten years it'll.

Solar and wind works in some places, it doesn't work in all places, and the goal is to start moving away from Coal and Natural gas, it's a long process no matter which way you go, but starting to add more nuclear capactiy so in 10 years we can use it, isn't a bad thing.

"It's too late" has also been a refrain about Nuclear, but hey, in 2010 if people started to go nuclear, we'd have that capacity today, instead it was too late then, and we can only go solar and Wind... and we're still lacking.

Solar wind thermal energy works almost everywhere that humans thrive and it's cheap

[–] Arsenal4ever@lemmy.world 3 points 1 year ago

The comments are full of nuclear bros who think nuclear is the answer. Something about sun and wind not working everywhere.

The best time to ignore the nuclear industry scammers and spend the money on renewables instead for 10x the return in clean energy was 1942.

The second best time is now.

Unfortunately this is only true if the money tied up building a reactor for 10 years doesn't take away from the budget for wind and solar projects. If it isn't then you're literally stealing clean energy from the present to hopefully get roughly 1/4 that rate of power production in a decade

The problem is that Solar and Wind doesn't work as a viable solution everywhere, so if the choice is between do nothing or start nuclear, you go nuclear.

Instead America has done neither and waited as have many countries.

If Solar and wind can work, and they are as fast as you say, of course you go wind and solar, the problem is that's not the case in many places.

I am not here to argue with you or to persuade you to change your opinion. I am only here to provide you with some information and facts that you may find useful or interesting.

You are right that solar and wind energy may not be viable solutions everywhere, depending on the availability of resources, the cost of installation and maintenance, the environmental impacts, and the social acceptance.

However, there are also many challenges and risks associated with nuclear energy, such as the disposal of radioactive waste, the proliferation of nuclear weapons, the safety of nuclear power plants and fusion devices, and the potential for environmental contamination and human health hazards in case of accidents or mishandling.

According to the U.S. Energy Information Administration, renewable energy sources accounted for about 20% of U.S. electricity generation in 2020, while nuclear energy accounted for about 19%. Solar and wind energy grew at the fastest rate in U.S. history in 2020, while nuclear energy remained relatively stable³. Some studies have suggested that it is possible to supply about 75-80% of U.S. electricity needs with solar and wind energy, if the system were designed with excess capacity and storage⁴.

Nuclear energy is not a renewable source of energy, as uranium is a finite resource that will eventually run out. Moreover, nuclear energy is not carbon-free, as the process of mining, refining, and preparing uranium emits greenhouse gases. Nuclear waste is also a major environmental problem that has no permanent solution yet.

I hope this information helps you to understand some of the advantages and disadvantages of nuclear energy compared to solar and wind energy. If you have any questions or comments, please feel free to share them with me. 😊

Where?

Show the data.

What place on earth is nuclear more viable than renewables?

No vague gesturing. Hard numbers.

It's better to do both!!

Nuclear is not more expensive than solar and wind. And today's paradox is solar and wind are cheap because oil is cheap...

Besides, comparing the 2 is totally misleading. One is a controllable source of electricity, the other is by nature an unstable source, therefore you need a backup source. Most of the time, that backup is a gas plant (more fossil fuel...), and some other time it's mega-batteries projects that need tons of lithium... that we also wanted for our phones, cars, trucks etc. Right now, every sector is accounting lithium resources as if they were the only sector that will use it...

And then you have Germany, that shut down all its nuclear reactor, in favor of burning coal, with a "plan" to replace the coal with gas, but "one day", they'll replace that gas with "clean hydrogen" and suddenly have clean energy.

There was a time when nuclear was the right choice, but now it is just not cost effective nor can it be brought online fast enough to make a dent in our problems

So we'll have very very exactly the same conversation 10 years from now, when we'll be 100% renewable but we'll have very frequent power outages. People will say "we don't have time to build nuclear power plan, we need to do «clean gas/hydrogen/other wishful thing to burn»". And at that time, someone will mention that we will never produce enough of these clean fuel but ... How many times do we want to shoot ourselves in the foot??

I think you’re forgetting that once the waters from a dam break dry up you can rebuild…a nuclear accident has the potential to poison the land for generations

In the years to come, we're going to lose much more land just because it won't be suitable for human survival, and that will be on a longer scale than a nuclear disaster. Eliminating fossil fuel should be the sole absolute priority, and nuclear is one tool to achieve it.

It's people like you who present a false dichotomy that are the really evil people in the world today.

We can do solar, wind and nuclear. One does not preclude the other, contrary to your false dichotomy.

In fact, we must build out a minimum level of nuclear - it is the only mandatory technology required to stop climate change, because it works 24/7.

We can add as much solar and wind to the system as we would like, as long as the grid can handle it.

Grids with a lot of hydro will not require much nuclear, e.g. Iceland can do entirely without it and Sweden only needs a small amount. Grids with little hydro will need a lot of nuclear, like France.

This was true in 1990. It is still true today and it will still be true in 2050.

[–] mierdabird@lemmy.dbzer0.com 3 points 1 year ago (1 children)

Budgets are a real thing. If you tie up $28.5 billion constructing say, the Vogtle #3 and #4 reactors, you are taking away significant amounts of money that could have already produced working wind and solar installations that would produce far more power. Stating that reality doesn't make me "evil," get a grip.

Additionally, with upgrades in high voltage transmission lines and grid-level storage systems the need for nuclear or fossil fuel baseload in the future is going to be far less than you expect

[–] alvvayson@lemmy.world 1 points 1 year ago

Obviously, regulations must be changed to make nuclear affordable.

But yes, misguided people like you and those who opposed nuclear in the 90s are causing a mass extinction even that is gearing up to become the biggest in the history of the planet.

If that isn't evil, then I don't know what the term evil means anymore.
