  • Four points:

    The profile of other is short spikes 5-100 hours a few times a year.

    1 year of delay is equivalent to 20 years of exclusively using fossil fuels for “other”.

    It’s not even obvious that adding nuclear reactors would reduce this because they’re so geographically and temporally inflexible. France has 63GW of nuclear capacity, <45GW of average load and 61GW of winter peak load with vast amounts of storage available via interconnect to hydro countries. They still use 5% gas on top of the rest of the “other” (which is about 10-25GW).

    5% of other from gas adds about 20g CO2e/kg per kWh to the total. Less than the margin between different uranium sources.

    Running 40% of the capacity 10% of the time puts your nuclear energy in the realm of $1-3/kWh. The list of ways of generating or storing 6% of your energy for <$1/kWh is basically endless.

    That’s about 4-8TW of capacity worldwide. 1kg of uranium is good for fuelling about 750W of reactor on a 6 year fuel cycle. Loading those reactors would require digging up all of the known and assumed-to-exist uranium immediately.

    Nuclear is an irrelevant distraction being pushed by those who know it will not work. You only have to glance at the policy history or donor base of the politicians pushing for it in Sweden, Canada, Australia, UK, Poland, etc etc or the media channels pushing it to see how obvious it is that it’s fossil fuel propaganda.

    It is obviously obviously true that it’s a non-solution. It fails on every single metric. All of the talking points about alleged advantages are the opposite of the truth without exception.









  • Part is the neoliberal economic model is really really bad at big projects. Part is the regulations and engineering complexity involved in not having them all shut down because they caught fire or the steam generators corroded (almost every program has “cheap” reactors at the beginning which have massive maintenance issues and leaks 10-30 years later, followed by expensive ones with massive delays). Part is corporate greed. Part is revealing and stopping rampant fraud and finding safety-compromising cost-cutting measures. Part is the lack of pressure from the military to make it happen as there is no longer a need for as much Plutonium. Part is that there actually are some semblance of environmental laws. Part is the fossil fuel industry interfering (as they do with all non-fossil-fuels).



  • Every year a reactor operates is a year of experiencing new ways they suck. The fixes and added complexities are rolled into the next reactor.

    Thr grifters running the show also learn new ways to grift, so the small new delays and costs are amplified.

    For older reactors the costs this imposes are rolled into operational budgets (and more often than not reactors are closed as unprofitable and the public or ratepayers are left holding the bag).

    Additionally regulatory agencies keep finding new instances of fraud, stopping these adds costs to the regulator and regulatee.

    This has happened since well before three mile island, so all misdirections to “scare mongering about meltdowns” are lies (the rate of cost escalation actually slowed significantly after three mile island).


  • More deranged doublethink.

    ARENH can’t be causing losses if the price it sets is profitable (so by citing it you are claiming that the french nuclear fleet has never broken even).

    It also can’t be causing a production shortfall requiring buying expensive hydro if the reactors are off because of a “strategy”.

    Your debt doesn’t go up every year if you’re making a profit.

    Deferring maintenance doesn’t make costs magically vanish.

    Decomissioning, waste management and hundreds of billions for license extensions are also completely unfunded. So the french people were just bilked another €10 billion for taking on a larger share of a half trillion dollar liability.



  • This is even more ridiculous.

    It’s sand. Literally the most abundant element in earth’s crust. And quartz sand isn’t even as particular as construction sand, because only the composition is important, not the shape.

    You’re literally pearl clutching about the scarcity of Silicon as a way of justifying calling it a rare earth.

    The only limitation is manufacturing, and you can build manufacturing and the output faster than you can build a nuclear reactor. You’re also comparing an industry that’s adding >300TWh/yr to one that is adding zero net (and about 20TWh/yr gross) as if the latter is significant and the former is not.

    The insane reaches that nukebros go to to justify their insanity would be comical if it wasn’t so harmful.







  • All thermal generation will cause direct global warming via waste heat if used to excess.

    Fossil fuels have an order of magnitude or two more thermal forcing via GHG, so it’s largely irrelevant there, but solar can produce a couple orders of magnitude more energy than the world uses now without significant land use. As such fusion (with the exception of p-B or He3 direct conversion with no steam engine which is a bit more scifi) hits thermal limits before solar hits land limits.

    Intuitively you can frame this as “a small fraction of the amount of sunlight that hits the planet is the amount of energy that changes the planet’s temperature” which is basically a tautology.
