I agree on them being safe - when rules are properly adhered to, they're extremely safe, similarly to air travel. People only suspect their safety because when they do fail, they tend to fail spectacularly, again similar to air travel.

Having said that, they may be efficient to operate, but they are by no means efficient to build. They cost a lot of resources, and have a 10 year lead time - plus you need to worry about the cost of waste storage and decommissioning.

So sure, nuclear is better than fossil fuels, but you're just kicking the nonrenewable can down the road.

That time and resources would be far better spent on renewables, because that where humanity is gonna have to go long-term no matter how well any other alternatives work.

Given that solar and wind are cheaper, get built to schedule and far less likely to have cost overruns, this meme is bullshit.

Sure, nukes are great. But we need clean energy right the fuck now. Spending money on new nukes is inefficient when it could be spent on solar and wind.

You know renewables aren't even the same thing as nuclear right? renewables aren't consistent and it's currently not possible to store the renewables anywhere.

We already have over-capacity of renewables.

Spending money on more doesn't help when there's no where to put that energy.

The best strategies are rarely single trick. Energy should be diversely sourced.

[–] [email protected] 26 points 6 months ago (4 children)

Correct, but don't forget that renewables is an umbrella term.

If you use solar, wind, hydropower, geothermal and bioenenergy, you're diversified and it's all renewable. Add in storage and there's not much of an issue anymore.

We already have 30% nukes. Right now we need more solar and wind. I’m not saying shut down nukes. They are good. They are just a waste of money and time to build new when we have cheaper and easier to produce alternatives.

Renewables are cheaper per kwh, but it's yet to be seen if they're cheaper when you get to higher grid renewable percentages and need to involve massive grid storage.

[–] [email protected] 9 points 6 months ago (1 children)

In the US we already have something like 30% which alleviates pretty much all the storage concerns. For our dollar right now, solar and wind are the best place to invest.

[–] [email protected] -2 points 6 months ago

Agree, but the leadtime is very long, so where's the best place to invest in 10 years? Hopefully the grid is much more renewable then.

Nuclear power relies on stable, safe, and advanced nations not like, I dunno, starting a land war in Europe that threatens to flood the continent with fallout.

@yogthos @spicytuna62 I don't mind nuclear but often those touting the virtues of nuclear energy implicitly want to prop up the crazy levels of inefficiency and overproduction of the current global economy with a cleaner energy source. If could stem the bleeding a little bit but the problems I mentioned will have to be addressed at some point.

Safe, sure. Efficient? Not even close.

It's far, far more expensive than renewable energy. It also takes far, far longer to build a plant. Too long to meet 2030 targets even if you started building today. And in most western democracies you wouldn't even be able to get anything done by 2040 if you also add in political processes, consultation, and design of the plant.

There's a reason the current biggest proponents of nuclear energy are people and parties who previously were open climate change deniers. Deciding to go to nuclear will give fossil fuel companies maximum time to keep doing their thing. Companies which made their existence on the back of fossil fuels, like mining companies and plant operators also love it, because it doesn't require much of a change from their current business model.

Blah blah blah nobody wants to hear actual evidence and suggestions that solar and wind might be better. We're on a mission for Nuclear power damn the Fukushima refugees and who cares if we store the waste encased in concrete at the bottom of the ocean which we know will eventually leak into the food stream

Noo kyaa larr is the fyuuu charrr

Cost billions and have 10 year lead times?

[–] [email protected] 5 points 6 months ago* (last edited 6 months ago) (1 children)

We're reaching the point where discussing cost in regard to the energy crisis makes us look like fucking idiots.

Imagine what kids reading the history books are going to think of these discussions.

And 10 years isn't that long really. If someone said we could use no fossil fuels in energy generation in 10 years time that doesn't sound long at all.

[–] [email protected] 27 points 6 months ago (3 children)

Cost is a proxy for productivity and resources. So while it is stupid to say that the energy transition is too expensive, shouldn't we rather invest our productivity and resources into a faster and cheaper solution? Drawing focus away from renewables is dangerous as others have mentioned, because it is too late to reach our goals with nuclear.

[–] [email protected] -1 points 6 months ago (1 children)

shouldn’t we rather invest our productivity and resources into a faster and cheaper solution?

We sure should. Do tell of this this faster, cheaper solution that is also adequate to meet all of our needs.

There are two main problems in my opinion, and they are both related to the "fuel". First, uranium is rare and you often need to buy it from other countries. For instance, Russia. Not great. Second, it is not renewable energy. We can't rely on nuclear fission in the long run. Then there's also the issue of waste, which despite not being as critical as some argue, is still a problem to consider

[–] [email protected] 11 points 6 months ago (2 children)

The mining is also usually a really polluting affair for the region, much more than the what power generation might suggest. And overall, in many countries there is a lot of subsidies going on for hidden costs, especially relating to the waste and initial construction. So it is not as cheap as a first look might suggest.

I'm not against it per se, it is better than fossil fuels, which simply is the more urgent matter, but it's never been the wonder technology it has been touted as ever since it first appeared.

Yeeeeah, I wouldn't worry about that. Sure we (Australia) are conservative with our fears of mining and exporting uranium, especially with the Cold War and reactor whoopsies around the world. But historically it doesn't take much for us to go down on an ally.

Just let us finish unloading all our coal off to the worst polluting nations first, then we'll crack the top-shelf stuff.

There are some reactor designs that run on waste of standard reactors. It would solve two of your points for at least some decades.

[–] [email protected] 11 points 6 months ago

It'd be nice to prioritise it at least rather than tucking it away under the oil and gas rug. There is no real competition in energy output to a nuclear power plant. And despite its egregious up front cost, operating it is relatively low cost.

In regards to fuel, uranium is used often but there is options such as thorium that have been used with some success. I do agree it is unfortunate to have to purchase from other countries but I think it beats buying natural gas from wherever it may be sold.

[–] [email protected] 42 points 6 months ago (1 children)

A big problem IMO is the generational responsibility of the waste as well. There needs to be decades of planning, monitoring and maintaince to ensure waste sites are safe and secure, this can be done but modern political climates can make it difficult.

[–] [email protected] 10 points 6 months ago* (last edited 6 months ago)

Agreed, dealing with the waste is a thing. But for me a solvable problem and something that doesn't need to be solved right away. We currently store a lot of nuclear waste in holding locations till we figure out a way to either make it less radioactive or store it for long enough. The alternative however is having coal plants all over the world spew all their dust (including radioactive dust) and CO2 straight into the atmosphere. This to me is a far bigger issue to solve. It isn't contained in one location, but instead ends up all over the world. It ends up in people's homes and bodies, with a huge impact to their health. It ends up in the atmosphere, with climate change causing huge (and expensive) issues.

The amount of money we need to handle nuclear waste would be orders of magnitude lower than what we are going to have to pay to handle climate change. And that isn't even fixing the issue, just dealing with the consequences. I don't know how we are ever going to get all that carbon back out of the atmosphere, but it won't be cheap.

Uranium is not that rare. Doesn’t Canada have quite a bit of it? Portugal used to mine it too, as well as several countries in Africa

[–] [email protected] 9 points 6 months ago

Yeah, countries obtaining uranium really isn't that big of an obstacle.
