    There are downsides to nuclear these days. Incredibly high cost with a massive delay before they’re functioning. Solar + wind + pumped hydro + district heating is where it’s at in 2024.

      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.

      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.

    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.

        That’s uhh, not what that says. One of the two mentions of half life are your body converting cyanide into thiocyanate, which will kill you and depending on your last bowel movement, make your corpse into hazardous waste itself.

        The other mention is hydrogen cyanide in air, which is lighter than air and will decompose back into cyanide eventually, scattering it over a large area. Which will technically make it go away from your site, but spreading toxic waste over the countryside is illegal for a reason.

    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.

    In Spain we are starting to get negative prices every weekend for electricity thanks to renewables. France is not even close to those prices with their bet for nuclear.

    Don’t get me wrong, I love nuclear power. And I’m not a big fan ok what thousands of windmills made to our landscapes. But efficiency wise renewable is unbeatable nowadays.

    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

    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.
