That’s not necessarily true. There is less need for them if NPPs are there, sure, but the price tag is always king. If renewables are simply much cheaper they will proliferate.

And we will always have to fill in the gaps for when renewables aren’t available. Betting it all on battery tech mostly coming from China is a dangerous game in this geopolitical era.

I don’t understand why people are so anti nuclear. It doesn’t have any emissions. The US, Canada and especially Australia have massive uranium reserves. It provides grid stability. Except for being expensive there is almost nothing going against it. And life cycle costs are likely coming down substantially in the near future with emerging technologies.

Renewables + Battery is the most cheapest way. If you don't want to import Batteries from China then you need to starz to build your own factories. Nuclear Reactors make you also depend on other countries.

I'm not directly Anti-Nuclar. I'm anti bad financial decissions. Spending so much money on Nuclear just to produce expensive electricity is just stupid. All the money needs to go to Renewables + Batteries, now.

Yes, but factories are expensive and cost a lot of time to build. So I’m not that sure about the financial picture of that either. Not to mention finding the space to put those factories + battery parks + more space for extra renewables to charge those batteries.

Nuclear also only makes Europe dependent on Canada or Australia, although Ukraine and Estonia have some too. The US has their own.

Not to mention batteries require a lot more resources. Whereas enriched uranium is only a few million tonnes per year, lithium- or sodium-ion battery technology requires resources that run in the trillions of tonnes. That’s because of the difference in energy density:

  • Pure U-235: 144,000,000 MJ/kg
  • Reactor-grade uranium: 3,456,000 MJ/kg
  • Sodium-ion battery: 0.27-0.72 MJ/kg

So to put this in perspective: to get the same energy that only 1 kilogram of reactor-grade uranium (at 3.5% U-235) provides, you would need sodium ion batteries with a total weight of 4.8 - 12.8 million kilograms.

Now of course batteries are reusable and nuclear fuel rods are only partly recyclable, but batteries don’t generate any energy by themselves. They need to be recharged with extra solar or wind power, on top of the ones directly feeding into the grid that you also have to build in even more factories, place onsite and individually connect to both the grid and the battery parks, etc.

This is a more rough estimate: but here they did the math:

A rough estimate suggests that about 3 million to 3.15 million solar panels may be needed to match the annual output of a large nuclear power plant

And even then you still haven’t solved what to do on all those quiet winter nights after an overcast day.

Betting it all on one horse it what’s stupid. Especially one that needs a mind boggling amount of resources. Yes we need to make batteries, but we also need to diversify and reduce dependency by expanding our nuclear power capacity.
