It's not necessarily the amount of waste that is the problem, it's the incredibly long duration of its radioactivity. At some point we will need super long term storage, and it's true that there is no viable solution out there yet. Even the most sophisticated facilities can not guarantee that no leakage will contaminate the surroundings at some point.
But as I said, I think finding a solution for this should not be our main priority.
You are right about the waste, it really sucks. But I still feel like abandoning nuclear energy now would be incredibly bad timing, given the urgence of reducing our carbon footprint. It's kind of ok not have a 100k years storage facility yet since it is a long term problem. Climate change is a problem we should have started tackling decades ago, and abandoning nuclear power might worsen it dramatically.
I agree. For me, the article absolutely did not deliver on what was said in the title. They declare efficiency as itself dangerous, where it is the narrow application of efficiency that really results in problens.
If you are so critical of the big media, then don't read them! There is plenty of other information that comes directly from scientists and is written for policymakers so anyone on HN should understand it. For example: read the summaries of ICCP Reports and please finally start taking climate change seriously.
