I did, I mostly agree with Sabine Hossenfelder, except for one thing: nuclear waste.
For a densely populated country like Belgium, there is no good way to handle that. We simply don't have space for it. So we need to export that waste. And that comes with a cost. Not only a monetary cost, I'm afraid. What happens when the destination is full, or when the country you export to simply stops accepting waste?
We've seen that happening with plastic and other non-nuclear waste. It was cheap to export that to Nigeria, or China. Both these countries stopped accepting waste from the west cause it simply polluted too much.
Waste is seldom "pure". Waste itself gets polluted because it's waste. Some unscrupulous individuals will mix it with other, more harmful stuff because that's where te money is. The same happens to nuclear waste. Sure, the used nuclear fuel itself will be pure, but there are so many other, less radio-active parts. Clothing, cleaning materials, even medical nuclear waste usually gets tossed in without much thought. And these often don't end up in the best of waste storage places.
And then there are mishaps like Fukushima and Tsjernobyl, rendering large areas uninhabitable for thousands of years. With a growing population, we simply can't waste valuable terrain like that. Developing small reactors will make that problem explode. Russia did that with their nuclear power cells for remote areas. These have been spread allover, after the end of the USSR. They might only contaminate a square kilometer, worst case, but there's 1200 of them allover Russia and probably a few have been knowingly or unknowingly exported elsewhere.
Nuclear is fine if all goes well. In case of war, or decay of government, they become an unknown frightfully fast. What if someone uses one of those to build a dirty bomb?
It seems to me that expensive, not renewable and high risk should be enough not to go in that direction, no?
