This is true for any other system of centralized energy production, including, notably, the one we have right now.
You underestimate the cost and lead times of the big distribution transformers found in grid substations. As an example, a fire two years ago on a substation transformer in the state of Amapá (while another transformer was broken and awaiting maintenance, and IIRC the third transformer of the set was also damaged by the fire) led to most of that state being without power for AFAIK nearly three weeks, until a replacement sent from another substation could be installed (and as a consequence, that other substation ended up without a spare until it could receive weeks later a replacement transformer from yet another substation). Note that building a new transformer instead of shuffling them between the substations wasn't an option, because it would take too long.
The most difficult part of the grid is the transmission infrastructure. The most valuable, high-lead-time part probably being the HV transformers that live near power plants.
One wonders whether famously-protected Finland keeps spares.
That doesn't sound like a very useful way to make decisions about anything except maybe missile defense and second strike capabilities. Anything can be destroyed with sufficient violence.
There's just no practical way to harden all of it against attack. And a tiny chance of some hypothetical future war isn't a good reason to choose a technology (combusting fossil fuels) that's gonna kill your own citizens every year, guaranteed. Why do your hypothetical future enemy's job for them?
If all you want to do is to knock out the electrical system of a country, you can use an EMP burst bomb over that country, and the grid will be down for months.

(Spoiler: there is no such material.)
The highly radioactive waste that lasts thousands of years is actually quite small.

Much of which stops being radioactive in the first year,

Which is to be expected given that a (tiny) part of the waste is long term.
The article says otherwise. You can remove "large" from your sentence.
Also, it looks like you've been repeatedly posting flamewar comments. Can you please stop? It's not what this site is for, and it destroys what it is for.
Even if you can design it in such a way that an external attack is very unlikely to cause a meltdown, it's a juicy and easy target for an adversary to cripple your electricity production. A few dozen well placed missiles might be all you need to take an entire nation that's heavily nuclear dependent to its knees.
On the other hand, solar and wind are hugely decentralized and distributed, making an attack that destroys these generators drastically more expensive. An adversary might still be able to take out the grid by targeting transmission infrastructure, but recovering from it should be relatively quick because the actual generators are all still intact.
But perhaps this flaw is alleviated by smaller scale reactors that produce a much smaller percentage of a region's electricity.
