    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.

      Australian politicians have been arguing about nuclear energy for decades, and with whats going on now, petty distracting squabbling while state governments are gutting public infrastructure

      The most frustrating thing is the antinuclear party is obviously fine with nuclear power, and nuclear armaments, just look at the aukus submarines

      labors cries about the dangers to our communities and the environment are obviously disingenuous, or they wouldnt be setting a green light for the billionaire robber barons to continue tearing oil and minerals out of the ground (they promise to restore the land for real-sies this time)

      Anyway, a nuclear power plant runs a steam turbine and will never be more than what, 30% efficient?

        Photovoltaic cells are even less efficient, I think they’re somewhere between 10-20% efficient. I think the way to go would be a solar collector, like the Archimedes death ray, but much much bigger.

          That is already a thing and it’s called concentrated solar power. Basically aim a shit load of mirrors at a target to heat it, run some working fluid through the target and use that to make steam to turn a turbine. There are a few power plants that use it but in general it has been more finicky and disruptive to the local environment than traditional PV panels would be.

          The fantastic thing about renewables is how much they lend themselves to a less centralised model. Solar collector? Sure, why not‽ Rooftop solar on people’s houses? You bet! Geothermal? If local conditions are favourable to it, absolutely!

          Instead of a small number of massive power plants that only governments or really large corporations can operate individuals can generate the power for themselves, or companies can offset their costs by generating a little power, or cities can operate a smaller plant to power what operations in their city aren’t handled by other means. It’s not a one-size-fits-all approach.

          This contrasts with nuclear. SMRs could theoretically do the same thing, but haven’t yet proven viable. And traditional plants just put out way too much power. They’re one-size-fits-all by definition, and only have the ability to operate alongside other modes with the other modes filling in a small amount around the edges.

        I would remind you that Aukus is a mess of the Coalition’s making - after they made a mess of the original submarine replacement project under Abbott and Turnbull, insisting on Diesel.

        But for Labor to withdraw from Aukus would cause a shitstorm of unseen proportions.

                  1. It’s not easy to go over all options.
                  2. Many of these are largely theoretical, or for temporary storage. For instance, I don’t think fluwheels can store energy for months.

        Redox flow, sodium ion, iron air, etc.

        There are some 600+ current chemical-based battery technologies out there.

        Hell for me, once sodium is cracked, that shit is so abundant that production wouldn’t have many bottlenecks to get started.

            Oil & Gas companies didn’t want Solar, Wind, and Storage to proliferate, yet they did because of cost savings.

            I think we could start to see that for these alternative-ion batteries if lithium supply ever becomes an issue. There will always be a niche that has the opportunity to grow in the economy. Just takes the right circumstances and preparation

        First, no, that’s not what I said. If you’re only going to be arguing in bad faith like that this will be the last time I engage with you.

        Second, baseload power is in fact a myth. And it becomes even worse when you consider the fact that nuclear doesn’t scale up and down in response to demand very well. In places with large amounts of rooftop solar and other distributed renewables, nuclear is especially bad, because you can’t just tell everyone who has their own generation to stop doing that, but you also don’t want to be generating more than is used.

        Third, even if you did consider it necessary to have baseload “until we have adequate storage”, the extremely long timelines it takes to get from today to using renewables in places that don’t already have it, spending money designing and building nuclear would just delay the building of that storage, and it would still end up coming online too late.

        I used to be a fan of nuclear. In 2010 I’d have said yeah, we should do it. But every time I’ve looked into it over the last 10 years especially, I’ve had to reckon with the simple fact that all the data tells us we shouldn’t be building nuclear; it’s just an inferior option to renewables.

          Aaaw, someone doesn’t like the tone used? Well that’s unfortunate. How about you start with leaving dem bad faith arguments?

          Renewables will not cover your usage. Period. You will need something to cover what renewables won’t be able to deliver. Your options are limited. Nuclear is the only sustainable option for many places. Sure you got hydro (ecological disasters) or geothermal in some places, but most do not have those options.

          It’s not an XOR problem.

              100% renew

              https://en.wikipedia.org/wiki/List_of_countries_by_renewable_electricity_production

              All the countries that manage 100% renewable power use high levels of hydropower. Which is not an option for many countries and has it’s own ecological problems associated with it.

              Also, these 100% renewable countries have very little electricity requirements.

              https://www.eia.gov/energyexplained/electricity/electricity-in-the-us-generation-capacity-and-sales.php

              The United States produces at least produces four million Gigawatt hours of electricity per year. Compare that to some of these “100% renewable” countries.

              • Sure, most countries that already made it use hydro. But Denmark is already up tp 80% without hydro, and the UK and Germany are already nearly halfway there without any meaningful hydro. And there’s still so much solar and wind that can still be installed. They’re nowhere near their maximum production capacity yet.

                100% from renewables is clearly feasible and achievable. Of course it takes time and investments, but nuclear energy will takre more time and investments to get going again.

                Just wait till you have to tell them they’re looking at irrelevant data. Not only are they using specific usecases that are not applicable to a large majority of countries, but they’re also using data that doesn’t support the long term fossil fuel goals.

                Just wait till you tell them how much the electricity requirements will skyrocket once we’re transitioning to EV, dropping fossil fuel heating, cooking, cargo trucks switch to EV, etc etc.

                Sorry to report, hydrogen is also hopeless. It’s cool tech, but making it work in practice is hopeless because it diffuses straight through every container you try and keep it in, and achieving reasonable energy densities requires cryogenic storage.

                Also, developments have been stalling out relative to electrical solutions because of this and because of the heavy investment in electrics.

                I can only see it really working in practice in niche applications where you will be close to cryogenic facilities.

                  Locking hydrogen up in ammonia is what the industry looks to be moving to to avoid the problem you describe.

                  Also, look up the 7 Hydrogen Hubs in the US as an example of this market getting started. There are no downsides to developing a hydrogen market if we’re going to have oodles of excess renewable energy.

      Agreed, building a nuclear facility takes a lot of time and costs a lot of money. However… This doesn’t need to be the case at all.

      A lot of the costs go into design, planning and legal work. The amount of red tape to build a nuclear plant is huge. Plus all of the parties that fight any plans to build, with a heavy not in my backyard component.

      If however a country would be prepared to cut through the red tape and have a standard design developed for say 10 plants at the same time, the price and construction time would be decreased greatly. Back in the day we could build them faster and cheaper. And these days we build far more complex installations quicker and cheaper than nuclear power plants.

      The anti-nuclear movement has done so much to hold humanity back on this front. And the weird part is most people do think nuclear fusion plants are a good thing and can solve stuff. But they have almost all of the downsides nuclear fission plants have in terms of red tape, complexity and cost.

        You can’t cut the red tape. The red tape is why we’re able to say nuclear is safe.

        the weird part is most people do think nuclear fusion plants are a good thing and can solve stuff. But they have almost all of the downsides nuclear fission plants have in terms of red tape, complexity and cost

        Huh? Nuclear fusion doesn’t have any downsides or upsides. Because it doesn’t exist. We’ve never been able to generate net power with fusion. (No, not even that story from a couple of years ago, which only counted as ‘input’ a small fraction of the total energy used overall. It was a good development, but just one small step on the long journey to it being practical.)

        Being anti-nuclear was a poor stance to have 20, 30 years ago. At that time, renewables weren’t cost effective enough to be a big portion of our energy generation mix, and we should have been building alternatives to fossil fuels since back then if not earlier. But today, all the analysis tells us that renewables are far cheaper and more effective than nuclear. Today, being pro-nuclear is the wrong stance to take. It’s the anti-science stance, which is why it has seen a recent rise among right-wing political parties and media organisations.

          I have never heard being pro-nuclear is the anti science stance and it being on the rise among right wing political parties. All the right wing is talking about it more coal and less things to be done about the climate.

          The people who I talk to who are pro nuclear seem very well informed and not anti science at all.

          I believe nuclear can help us get to the future we want and we should have done it a lot sooner. Nuclear doesn’t mean anti-renewable, both can exist.

            Nuclear is a possible solution to more power.

            However as long as we can’t use the old nuclear waste as fuel we are not going to have to way to get uranium in way that is human and affordable.

            Also nuclear power plants are expensive as fuck. You will pay several billions of euros in order to build one. You will have at least 10 years of building time. In that time the power demand may already have been doubled tripled or quadrupled. So are you ready to build 4 times as much of hundreds billions worth of power plants in the hope you finish them on time or don’t over build?

            Or do you want to build a solar plant or a wind farm in several months once demand has increased? For a fraction of the costs?

            Nuclear doesn’t mean anti-renewable, both can exist.

            Not easily, for the reasons explained in my reply to @Frokke@lemmings.world.

            The people who I talk to who are pro nuclear seem very well informed

            I doubt it, because the science itself is against nuclear. Evidence says it would be too expensive and take too long to deliver compared to renewables.

              Very well, let’s agree to disagree. Perhaps I am wrong. But I am in no way right wing or spreading misinformation.

              The people I’ve spoken who work in the nuclear field bitch about unneeded red tape all the time. Some of it is important for sure, but a lot of it can be cut if we wanted to without safety becoming an issue. The price of nuclear has gone way up the past 20 years, whilst the knowledge and tools have become better. This makes no sense to me. We should be able to build them cheaper and faster, not slower and more expensive. And there are countries in the world, that can get it done cheaper, so why can’t we?

              I’m all for renewables, I have solar panels. But I’m not 100% convinced we have grid storage figured out. And in the meanwhile we keep burning fossils in huge amounts. If we can have something that produces energy, without fucking up the atmosphere, even at a price that’s more expensive than other sources (within reason) I’m all for that. Because with the price of energy from coal, the money for fixing the atmosphere isn’t included.

              Thank you for answering in a respectful manner.

              • We should be able to build them cheaper and faster, not slower and more expensive. And there are countries in the world, that can get it done cheaper, so why can’t we?

                It’s because we stopped building them. We have academic knowledge on how to do it but not the practical/technical know-how. A few countries do it because they’re doing a ton of reactors, but those don’t come cheap either.

        If however a country would be prepared to cut through the red tape and have a standard design developed for say 10 plants at the same time, the price and construction time would be decreased greatly.

        That’s a pretty big ask for a democratic government where half of the politicians are actively sabotaging climate initiatives…

        The only countries where this is really feasible are places where federal powers can supersede the authority of local governments. A nuclear based power grid in America would require a complete reorganization of state and federal authority.

        The only way anyone thinks nuclear energy is a viable option in the states is if they completely ignore the political realities of American government.

        For example, is it physically possible for us to build a proper deep storage facility for nuclear waste? Yes, of course. Have we attempted to build said deep storage facility? Yes, since 1987. Are we any closer to finishing the site after +30 years…no.

      This.

      Also, tie together more countries’ power grids to even out production and demand of renewables, and reduce the need for other backup sources.

      For a fraction of the cost of nuclear, increase the storage capacity as well. We’ve had days where the price per MWh was negative in many hours, because of excess production.

      The barriers to carbon free energy aren’t technical, they’re purely political.

        Yeah, back in 2010 and before nuclear was the way to go but with the incredible advancements in solar and wind it’s no longer the best option.

                  No, there is pumped storage. Honestly, despite the plethora of start-ups claiming to have a solution (sodium batteries, molten-salt, etc) The only really proven way to store electricity for later is pumped storage, but that relies on geography (hills) which not everyone has. Batteries are great for phones, and cars but they simply don’t scale to countries.

                  Or convert excess to hydrogen and provide resilience, or have arrangements for industry to consume the excess. Or ramp down your generation at those times. Or shift excess to neighbouring grids.

            it has got cheaper, but it has to get cheap enough that you can buy enough batteries with the difference. I’m not sure it has become that cheap. Maybe these sodium battery things will get developed.

          You probably also didnt heard about Thorium based molten salt reactors, they are much safer than conventional nuclear, also cheaper, and you can have a 50MW installation in space not much larger than a shipping container. A 50MW solar installation is close to 1km2 and thats without any storage included. It even can be modified to run on spent fuel of conventional nuclear power plants.

        Please understand that negative prices are the market for electricity breaking down! That is not a good thing. It should mean that if you have solar panels on your roof you have to pay to participate in the national grid because you are dumping energy into the grid when it can’t use it, but special rules have been made for renewable plants. Literally, imagine a contract-to-supply for wind or solar…

          I understand very well the implications of the negative price, which is why I advocated NOT to spend trillions in nuclear, when issues of balancing demand and production can be solved for a fraction of what nuclear costs.

      Still not a reason to not build them, the entire point is for nuclear to handle the load when solar/wind can’t provide due to weather. Other renewables will still be producing the bulk of the power we need, but at night nuclear will be handling any demand spikes, each of them would greatly reduce the number of batteries required to satisfy the demand. They can stay until our solar output is so high we can just start electrolyzing water into hydrogen as energy storage.

          Though pumped hydro is sometimes opposed by environmental groups because it does absolutely decimate local environments.

          I have high hopes for sodium batteries. The ones that have been released on the market are simply perfect (if scaled up) for local grid storage in countries with a lot of space and will hopefully get better energy density in line with Lithium Iron Phosphate with time.

          Salt batteries have been the cold fusion of battery tech for like 10 years, but now it is finally coming to fruition. I hope to install a solar installation with salt batteries in 5 years or so, myself.

        If you’re suggesting using Nuclear as a peaker plant or to turn it off and on whenever wind/solar is not up for it then I’m sorry to say that it’s not viable. Nuclear generators don’t handle well being turned off and on.

      You can make Thorium reactors much smaller and cheaper, basically a 50MW unit is not much larger than a shipping container, while being much more safe than standard nuclear plants. The largest issue is over-regulation of the nuclear power in general.

      A 50MW of solar installation is HUGE, and thats 50MW at the sunniest part of the planet: https://newsaf.cgtn.com/news/2019-12-15/Kenya-launches-Chinese-built-50MW-solar-power-plant-MqC575l6Te/index.html, We are basically talking about close to a square kilometer installation…

      there is simply no way to call a 50MW solar plant cleaner than nuclear and its probably not even that much cheaper in the end. Compare that to a shipping container sized reactor… Only thing in the way, is the nuclear scare and government regulations.

    Hi, I work in waste handling, and I would like to tell you about dangerous materials and what we do with them.

    There are whole hosts of chemicals that are extremely dangerous, but let’s stick with just cyanide, which comes from coal coking, steel making, gold mining and a dozen chemical synthesis processes.

    Just like nuclear waste, there is no solution for this. We can’t make it go away, and unlike nuclear waste, it doesn’t get less dangerous with time. So, why isn’t anyone constantly bringing up cyanide waste when talking about gold or steel or Radiopharmaceuticals? Well, that’s because we already have a solution, just not “forever”.

    Cyanide waste, and massive amounts of other hazardous materials, are simply stored in monitored facilities. Imagine a landfill wrapped in plastic and drainage, or a building or cellar with similar measures and someone just watches it. Forever. You can even do stuff like build a golfcourse on it, or malls, or whatever.

    There are tens of thousands of these facilities worldwide, and nobody gives a solitary fuck about them. It’s a system that works fine, but the second someone suggests we do the same with nuclear waste, which is actually less dangerous than a great many types of chemical waste, people freak out about it not lasting forever.

    Just because it’s safe doesn’t mean it’s the best we have right now.

    • It’s massively expensive to set up
    • It’s massively expensive to decommission at end of life
    • Almost half of the fuel you need to run them comes from a country dangerously close to Russia. (This one is slightly less of a thing now that Russia has bogged itself down in Ukraine)
    • It takes a long time to set up.
    • It has an image problem.

    A combination of solar, wind, wave, tidal, more traditional hydro and geothermal (most of the cost with this is digging the holes. We’ve got a lot of deep old mines that can be repurposed) can easily be built to over capacity and or alongside adequate storage is the best solution in the here and now.

    lol nuclear is really uneconommical, way too expensive and therefore really inefficient. You need 10-20 years to build a plant for energy 3 times more expensive than wind. For plants that still require mining. That produce waste we cannot store and still cannot reuse (except for one small test plant). For plants that no insurance company want to insure and energy companies dont like to build without huge government subsidies.

    I know lemmy and reddit have a hard on for nuclear energy because people who dont know anything about it think its cool. But this post is ridiculous even for lemmy standards.

    I’m pro nuke energy but to pretend there are no downsides is what got us into the climate mess we are in in the first place.

    Cost, being a major drawback, space being another. And of course while they almost never fail, they do occasionally, and will again. And those failures are utterly catastrophic, and it’d hard to convince a community to welcome a nuclear plant, and if the community doesn’t want it then it can’t or shouldn’t be forced onto them.

    They also represent tactical strike sites in time of combat engagement. Big red X for a missile.

    There are also significant environmental concerns, as we really have no good way to dispose of nuclear waste in a safe or efficient manner at this time.

    It’s likely that nuclear based energy is the future, but you need to discuss the bad with the good here or we are just going to end up at square one again. There are long term ramifications.

      They don’t need to be exclusive. Power generation should be diverse. Otherwise prices will go through the roof on times without wind (happens in Germany). This can lead to higher energy prices in combination with high energy exports.

          True, it wouldn’t be enough, This is why Germany still has a lot of coal-fired power station and natural gas power stations, despite huge investments into renewables, and is also investing a lot into wood-fired power stations (imo a really terrible idea). The nuclear plants could still ease the situation by giving a stable basic load that has some planable variability (wind models are getting also better every year and aren’t that bad as it is). For now renewables cannot really provide a very stable basic load (at least not here, might be different for other areas).

          There are great concepts to improve all of this with stuff like pumped-storage hydroelectricity, but those cannot be build everywhere and take up a lot of space. It is going forward and I think nuclear power will come to an end eventually. For now, I think they still have their place (and imo Germany acted irrationally by shutting them all down).

          I mean, we’ve been lucky that France completly fucked their energy sector up (hints towards that nuclear plants probably also won’t be the ultimate solution), otherwise we’d have lost a loooot of money and would have had energy prices even worse.

      Negative energy prices are a bad thing! That means that someone is dumping energy into the grid (you should be paying the grid if you have solar panels!!) In the UK all renewable energy had to be called ‘experimental’ so that the pricing was fixed and the government picks up the tab - that’s not good. Check this map - right now the wind isn’t blowing and solar hasn’t got out of bed - so most of the countries using renewables are looking shit - later today solar will kick in, but tonight it will be bad again. That isn’t a solution.

      Energy is expensive in France because we are legally forced by european regulation to sell at those prices. Our energy is the least expensive to produce

    Deep level irony that you used a Simpsons meme, which takes place in a city that suffers from a Nuclear Power Plant that doesn’t dispose of nuclear waste properly.

    Every form of energy generation is problematic in the hands of capital. Security measures can and are often considered unnecessary expense. And even assuming that they will respect all safety standards, we still have the problem of fuel: France, for example, was only able to supply its plants at a cheap cost because of colonialism in Africa. Therefore, nuclear energy potentially has the same geopolitical problems as oil, in addition to the particular ones: dual technology that can and is applied in the military, not necessarily but mainly atomic bombs.

    Also, I thought memes were supposed to be funny…

    literally the least efficient in terms of cost and time.

    battery backed renewables are a fraction of the price and are being deployed right now.

    edit: the tech is cool as hell. go nuts on research reactors. nuclear medicine has saved my sisters life twice… but i’m sorry, its just not a sane solution to the climate crisis.

    If you’re interested in energy solutions and haven’t read the RethinkX report on the feasibility of a 100% solar, wind and battery solution, it’s definitely worth taking a look.

    Whilst I agree that we need to decarbonise asap with whatever we can, any new nuclear that begins planning today is likely to be a stranded asset by the time it finishes construction. That money could be better spent leaning into a renewable solution in my view.

      Exactly this. I am “in favor” of nuclear energy, but only in the sense that I’d like fossil power to be phased out first, then nuclear. Any money that could be spent on new nuclear power plants is better spent on solar and wind.

        I’d like Nuclear power not to be thrown out with the bathwater because it is practically essential for space travel/colonization in the long term. Solar panels can only get us so far, and batteries are a stop-gap. We need nuclear power because it is the only energy source that can meet our needs while being small enough to carry with us.

        All should praise the magic, hot rocks.

          Seems like it’s pretty important we not burn through our finite reserves of it if we can help it. I’m not saying we should reach zero nuclear, but I don’t think we should be relying on it too much either.

            We are no where near close to running out of nuclear material. And for its energy density, we are unlikely to run out anytime in the next 10000 years. It can also be found in asteroids or other rocky bodies, so unlike wood or fossil fuels, Earth isn’t the only place to get it.

      The materials needed to produce batteries and wind turbines and maintain them over time is the issue. Did your 62 page report discuss this?

      Does it cover everyone on the planet using the same amount of electricity as a North American? 8 billion people now. And usage is increasing too, gotta power EVs and AI (but not limited to that).

        im fine with dropping AI for more humans right now, but apparently that wont generate shareholder value.

          First it doesn’t matter because it’s going to happen whether we want it to or not.

          Second the whole point is that electricity use per capita is always increasing.

            Nah, they won’t. It goes bling-bling, has a couple of good use cases, but because it generates Market Hype, Companies will cram it into everything. And i hate it.

    Nuclear lobby really tries to sell us to the fact, that it’s better to have control over power by a few big players. Must be terrifying to think about people creating their own power eventually.
