    do not let “perfect” be the enemy of “good enough”

    edit: quick addendum, I really cannot stress this enough, everyone who says nuclear is an imperfect solution and just kicks the can down the road – yes, it does, it kicks it a couple thousand years away as opposed to within the next hundred years. We can use all that time to perfect solar and wind, but unless we get really lucky and get everyone on board with solar and wind right now, the next best thing we can hope for is more time.

      I completely agree with everything you said except for ONE little thing:

      You are grossly misrepresenting how far that can is kicked down, for the worse. It doesn’t kick it down a couple thousand years, it kicks it down for if DOZENS of millennia assuming we stay at the current energy capacity. Even if we doubled or tripled it, it would still be dozens of millennia. First we could use the uranium, then when that is gone, we could use thorium and breed it with plutonium, which would last an incomprehensibly longer time than the uranium did. By that point, we could hopefully have figured out fusion and supplement that with renewable sources of energy.

      The only issue that would stem from this would be having TOO much energy, which itself would create a new problem which is heat from electrical usage.

      Why is it supposed to be easier to get people onboard with nuclear (which is decreasing) than wind and solar (which are increasing at triple the rate of the nuclear construction peak in the 80s and growing at 20% p.a.)?

      People are on board with VRE. Some of the are on board with nuclear too, but it’s not working.

        Nucleur isn’t all it’s cracked up to be, maybe it would be economical if we had heavily invested in the tech decades ago. But current plants have major issues, here is a snippet from another article:

        The study also questions the reliability of the nuclear fleet, particularly given the dramatically low availability of French power plants this year – nearly half of the 56 nuclear reactors were closed even though the EU was in a complicated period of electricity supply with frequent peaks in the price of electricity above €3/kWh.

        The availability of this electrical source is also questioned in view of the increasingly frequent droughts expected in the coming years, causing, in particular, low river flows and therefore associated problems of cooling power plants.

      I really cannot stand that phrase because it’s commonly used as poor rationale for not favoring a superior approach. Both sides of the debate are pushing for what they consider optimum, not “perfection”.

      In the case at hand, I’m on the pro-nuclear side of this. But I would hope I could make a better argument than to claim my opponent is advocating an “impossible perfection”.

        But that is exactly what’s happening. People are pretending like the alternative to investing in nuclear is living off 100% renewables from tomorrow.

      Buying time isn’t a great argument for nuclear when it takes so much longer than wind or solar to build a plant - median time of 88 months to build a nuclear plant compared to 8-14 for solar.

      People will get on board when they see the cost per kwh.

          Which isn’t unusual for large construction projects. Nuclear is biggest cost problem is that each power plant is essentially a mega civil engineering project. They require cooling ponds, cooling towers, huge reactors, turbines, and radiation shields.

          All of which are fairly large structures that have to be built to pretty high tolerances and have little room for construction defects which are very common in the industry. I work in construction and I can tell you that the majority of construction projects, whether they are an office building, a highway or a bridge run over budget.

          There are always going to be factors outside of the control of the design team and the developer. Contractors may run out of labor, supply chains may have many years to complete some of the equipment and these issues compound the schedule which is already very complicated. Do we have an even discussed the expanded and politicized planning and safety rules and certifications that a new nuclear plant is going to need to follow.

          I think the solution for micro reactors is pretty intriguing, except we need lots of power not small amounts of power. But a mass-produced reactor that rules off of an assembly line in a factory is likely to be on time and on budget because they can correct for for the problem of building things in the field. It’s really hard for people to fabricate complicated machines when they’re being rained on in the middle of winter during a storm.

      The problem with Nuclear’s “good enough” is that Nuclear is currently worse than other technology we have in almost every way.

      1. Higher total lifetime cost per kwh than solar or land-based wind (and hydro, but that’s niche), even after factoring in capacitors for weather and time of day/year
      2. Awkwardly front-loaded TCO. You basically pay a huge percent of that ugly TCO up front, making Nuclear more prohibitively expensive than its modest total lifetime cost would imply.
      3. Long life. This is a terrible thing. TCO’s of solar and wind plants are predicated upon a 20 year obsolescence. That means, the TCO includes the cost to build, tear down, and make way for the inevitable better tech in 20 years. Nuclear plants are priced at 50+ year lifetimes. You can’t easily retrofit a nuclear plant with better technology if/when it starts to catch up.

      It is absolutely true that solar and wind are better because more money has gone into their research. But because of that, they are better options in almost all real world power situations.

      The problem with focusing on nuclear is… why waste all that political capital just to spend 100x the money or more that you could spend to be 100% renewbles in the short term? The front-loaded TCO is the real issue with that one. If you wanna hit 0 emissions tomorrow with Solar/Wind, you’re just paying the up-front costs, knowing there are per-year costs (still cheaper than fossil fuels) to keep it going. If you want to do the same with nuclear, you’re paying for almost all of it out of the gate for 50 years worth. Suffice to say, that’s a budgeting nightmare.

      And what’s left is space. Nuclear creates a lot of power in a small area. But wind and solar are both far more easily/efficiently integrated into the space we are already using.

      But this is my argument against those who complain about Solar and Wind – those won’t kill you or destroy a location for hundreds of years if they break down and once they’re installed they don’t have to be fed by more mining, or anything else. Just wind and sun.

        Funny you say that. Solar and wind each have more human deaths per kWh than nuclear.

        Worth mentioning that fossil fuels blow those numbers completely out of the water, though.

              The death rate for nuclear was mostly from Fukushima, where about 2,300 elderly people died from the stress of moving from their homes. But their houses were also wiped out from a 35 ft tsunami so…

              Chernobyl and Fukushima didn’t directly kill very many people. Only 1 person died from radiation at Fukushima.

              From the author:

              "People often focus on the marginal differences at the bottom of the chart – between nuclear, solar, and wind. This comparison is misguided: the uncertainties around these values mean they are likely to overlap.

              The key insight is that they are all much, much safer than fossil fuels.

              Nuclear energy, for example, results in 99.9% fewer deaths than brown coal; 99.8% fewer than coal; 99.7% fewer than oil; and 97.6% fewer than gas. Wind and solar are just as safe."

      This attitude is about a decade out of date. It made sense around 2010 when wind and solar weren’t widely deployed and cost more than nuclear per megawatt hour. Now we have more wind and solar deployed than nuclear, and they’re significantly cheaper and faster to construct and make better economic sense than nuclear.

        I hear this point all the time, but it’s simply not true. The total power that humanity consumes could perhaps eventually be generated with wind and solar, but they don’t generate on demand, scalable power to provide the actual base load needed.

        Don’t get me wrong, I think every new building (and probably the old ones too) should have solar panels, but that doesn’t negate the need to move the base power generation to nuclear from coal and oil.

          This is why people now compare cost of nuclear with cost of solar PLUS capacitors/batteries to handle for base load. Surprisingly, with recent achievements in molten sand batteries, solar is still comfortably cheaper than nuclear per kwh. As the base load.

          And solar’s cost is far less front-loaded, making it more affordable than the “cost per kwh” implies.

          The point is, if we are not at the point of moving our base load to renewables today, we would be faster than we would be with nuclear and provisioning all the locations needed for secure, regulated, nuclear plants across the country/world. And the “world” part is a big one. Nuclear power material might not be fully weaponizable, but allowing some countries nuclear power plants could still create risk.

      I fail to understand how managing wastes remotely toxic to all forms of life for 500K years would be economicaly viable. This just calls for increasingly more power demand. It is hard to sell when there are alternatives that are cheaper, cleaner, more scalable, easier to build (eg offshore wind).

        There are no available technologies safer than nuclear, unless you’re talking about the construction. You’re literally more likely to fall and hit your head on a solar panel. Which can be serious electrical hazards for firefighters if you’re ever unlucky enough to get caught in a house fire.

          In a stable world yes, but we also wouldn’t have all those news when Russia puts boxes on solar panels instead of nuclear reactors and we don’t need no fly zones and fog machines around wind turbines.
