Because your government said reprocessing was not allowed, there is now an excess of nuclear material. Ergo, reprocessing is a bad technology
Thank you for illustrating my point. The tech is sound. Getting past the fearmongers and actually using it is the problem. We have had some ridiculously safe reactors for decades, we just aren't allowed to build or use them anywhere. We have ways to deal with waste, but we aren't allowed to do it... and then get yelled at for having excess waste.
Seriously. Put your prejudices and patriotism at the door and actually do some research on the subject. Yes, a lot of this hasn't been tested at scale (in large part because politicians and Activists won't let anyone) but they have been researched VERY heavily, tested at varying scales, and are a more viable alternative than anything else right now. But because there is a "nuclear" in the name, it is inherently evil and wrong.
