Fossil fuels are only as cheap as they are because of subsidies. We should remove the fossil fuel subsidies from the equation then if we want to talk actual cost.

That's about $30 Billion each year in the US, $660 Billion or so internationally. And that's only direct subsidies. Granted, that's total fossil fuel subsidies not just energy related, it's much more complicated to split it out, and this is a random Lemmy comment so not worth the time.

And since we don't really tax carbon pollution at any discernable level, if we actually required that to be included for the environmental damage from fossil fuel energy production, since we do require nuclear plants to plan for their waste production, it wouldn't be even close to competitive at all.

Nuclear is not feasible and will never be.

For starters, it's expensive. Really expensive. Insanely expensive. It also takes years to go online, and decades to decomission (which should be paid by the owner, but sometimes ends up being paid by the government because the owner went bankrupt or exploited a loophole). It's also not quickly variable, so it needs a very constant demand.

Instead of investing in nuclear, one could invest in solar and wind. The latter can produce energy all day long, and if you have enough locations with wind farms, it starts averaging out and becoming constant. Both wind and solar are also quickly variable, so they can easily adapt to demand. They're incredibly inexpensive and pay for themselves in a few years.

Batteries in the distribution network aren't a good idea, and they're also probably not gonna work. Even though they're still cheaper than a nuclear plant, they're pretty expensive and they have a lot of wear. Technologies have been advancing really fast, and we already have prototypes that look promising. However, they don't make that much sense when you look at alternatives like pumped hydro. Pumped hydro is cheap, has a lot of capacity, can also quickly adapt to demand, and requires less maintenance than nuclear or batteries.

Another solution for energy storage is personal battery storage, which people install in their homes. Almost everyone who has solar already has a battery in their house, and even people without solar buy batteries to charge during the night and use up during the day. These batteries can be made with recycled electric car batteries, so they're also carbon neutral and cheap.

And this is all without touching on the real issue of nuclear waste, which nuclear promoters always sweep under the rug. Yes, the amount of nuclear waste produced is minuscule. Yes, it's not dangerous at all as long as it's properly dealt with. Yes, it's still better than the massive amounts of pollution that fossil fuels create. But it's still a form of pollution, it's dangerous when mishandled, and most importantly, it has to be kept in storage facilities for thousands of years. Those storage facilities are paid for by governments, which in turn are financed by our taxes. And we can only keep building them, because no waste goes out and new waste keeps going in. So even if the number in our electricity bill is small, we still pay more costs related to nuclear with our taxes.

TL:DR: Nuclear is expensive and slow to build and doesn't adapt well to the variability of demand. Renewables, especially solar and wind, are cheap and effective, and there are many ways (not just batteries) to efficiently store excess energy to use during periods of low production. Nuclear also generates waste, which even though it may not be dangerous, is still expensive to store for thousands of years.

Disclaimer: I'm not endorsing fossil or non-renewable energy in any way, I'm all for net zero energy production. But nuclear is not net zero and not a good solution. We can completely ditch fossil fuels without relying on nuclear, and it can work. I live in a country where we're decomissioning nuclear plants and we generate more than 50% of our electricity from renewables. On average, we generate close to the same amount of energy from wind than from nuclear (~20%).
