  • 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.

  • I'm sure nuclear can be super safe and efficient. The science is legit.

    The problem is, at some point something critical to the operation of that plant is going to break. Could be 10 years, could be 10 days. It's inevitable.

    When that happens, the owner of that plant has to make a decision to either:

    1. Shut down to make the necessary repairs and lose billions of dollars a minute.
    2. Pretend like it's not that big of a deal. Stall. Get a second opinion. Fire/harass anyone who brings it up. Consider selling to make it someone else's problem. And finally, surprise pikachu face when something bad happens.

    In our current society, I don't have to guess which option the owner is going to choose.

    Additionally, we live in a golden age of deregulation and weaponized incompetence. If a disaster did happen, the response isn't going to be like Chernobyl where they evacuate us and quarantine the site for hundreds of years until its safe to return. It'll be like the response to the pandemic we all just lived through. Or the response to the water crisis in Flint Michigan. Or the train derailment in East Palestine.

    Considering the fallout of previous disasters, I think it's fair to say that until we solve both of those problems, we should stay far away from nuclear power. We're just not ready for it.

  • Nothing about nuclear energy production is good, sensible and safe! You are dependent on a finite resource, you have to put in an incredible amount of effort to keep it running. Not to mention the damage caused by a malfunction (see Fukushima and Chernobyl).

    • What are you even talking about?!?! There is so much uranium in the world. Even if we completely switched over to nuclear power and without improvements in Nuclear tech, our sun would have fizzled out and we still would have uranium left.

      Uranium is more abundant than silver and we don't need much to power a nuclear reactor.

      I like how people take Fukushima and Chernobyl as examples for disasters. Please go look up how many people have died from those disasters. Please go check. I'll wait.

      Chernobyl: 2 Fukushima: 0

      Keep in mind that Chernobyl was built in the 50s with 50s tech it never maintained during the USSR era.

      Fukushima did not anticipate a tsunami. Because of the Fukushima disaster we know have new protocols to improve future nuclear builds. If anything Fukushima is a prime example how safe a nuclear reactor can be even when the worst scenario happens.

Uranium is more abundant than silver and we don't need much to power a nuclear reactor.

        And yet we would still be dependent on an industry, just as we are today on coal, gas and oil.

        As others have already answered: far more people died than you claim here! How much land was made uninhabitable for centuries? How many animals would have to die? How much food would have to be destroyed because it was contaminated? What happens if a tsunami hits an offshore wind farm? They collapse... And then? Do they have to be rebuilt?But you can do that because the land has not been contaminated

      • I like how people take Fukushima and Chernobyl as examples for disasters. Please go look up how many people have died from those disasters. Please go check. I'll wait. Chernobyl: 2 Fukushima: 0

        Are you really that dillusional that you think that the only casualties are the people who died in the incident? Hundreds of peoples suffered from cancer and other long term effects alone in chernobyl. The area is still hazardous to people (as some 'clever' Russian invaders just proofed two years ago)

        Please go check. I'll wait.

        PlEaSe Go ChEcK. I'lL wAiT.

        ...

        Please just grow up, kiddo

      • There is so much uranium in the world. Even if we completely switched over to nuclear power and without improvements in Nuclear tech, our sun would have fizzled out and we still would have uranium left.

        TL;DR: If we switched over to nuclear, weโ€™d burn through the worldโ€™s reserves of accessible uranium ore in less than twenty years. Hopefully the sun will last a bit longer than that.

        According to 2022 Red Book, there are around 8 million tonnes of Uranium which we could extract for $260 or less, per kg. The current price for uranium is around half that, FYI, so nuclear fuel prices would have at least doubled by the point weโ€™re extracting that last million tonne.

        Nuclear power plants use around 20 tonnes of uranium per TWh, according to the world nuclear association, and world energy consumption is around 25,000 TWh per year, according to the IEA. That would be half a million tonnes of uranium consumed per year. Meaning we would burn through the worldโ€™s reserve of reasonably accessible uranium in just sixteen years.

      • Furthermore, any energy production that has the potential to injure, harm or kill thousands of people cannot be considered safe. Just because nothing has happened so far.

  • My issue with nuclear energy isn't that it's dangerous or that it's inherently bad. The world needs a stable source of energy that compensates for wind and solar fluctuations anyways. For the current realistic alternatives that's either going to be nuclear or coal/oil/natural gas. We have nothing else for this purpose, end of discussion.

    My problem is the assumption underlying this discussion about nuclear energy that it somehow will solve all of our problems or that it will somehow allow us to continue doing business as usual. That's categorically not the case. The climate crisis has multiple fronts that need to be dealt with and the emissions is just one of them. Even if we somehow managed to find the funds and resources to replace all non renewable energy with nuclear, we would still have solved just 10% of the problem, and considering that this cheap new energy will allow us to increase our activities and interventions in the planet, the situation will only worsen.

    Nuclear energy is of course useful, but it's not the answer. Never has technology been the answer for a social and political issue. We can't "science and invent" our way out of this, it's not about the tech, it's about who decides how it will be used, who will profit from it, who and how much will be affected by it etc. If you want to advocate for a way to deal with the climate crisis you have to propose a complete social and political plan that will obviously include available technologies, so stop focusing on technologies and start focusing on society and who takes the decisions.

    One simple example would be the following: no matter how green your energy is, if the trend in the US is to have increasingly bigger cars and no public transport, then the energy demands will always increase and no matter how many nuclear plants you build, they will only serve as an additional source and not as a replacement. So no matter how many plants you build, the climate will only deteriorate.

    This is literally how the people in charge have decided it will work. Any new developing energy source that is invented serves only to increase the consumption, not to replace previous technologies. That's the case with solar and wind as well. So all of this discussion you all make about nuclear Vs oil or whatever is literally irrelevant. The problem is social and political, not technological.

  • No, it's not the best we have. Solar and wind are way safer, cost less and don't produce waste.

    Sure, nuclear power is safe until it isn't. Fukushima and Chernobyl are examples of that. Nuclear plants in Ukraine were at risk during Russian attacks. Even if you have a modern plant, you don't really think that under capitalism there is an incentive to care properly for them in the long run. Corners will be cut.

    Besides that they produce so much waste that has to be: a) being transported b) stored somewhere

    Looking at the US railroad system and how it is pushed beyond it's capacity right now and seeing how nuclear waste sites are literally rotting and contaminating everything around them I'd say it's one of the least safe energies. Especially if you have clean alternatives that don't produce waste.

  • Solar and wind will always need batteries for times of low output, until we get more resilient and larger capacity batteries we will need a backbone to support the electricity grid to avoid having to overbuild battery capacity.

    As of right now natural gas is that backbone but that could change and very well be nuclear energy until we figure out something like mass produced solid state batteries.
