Many view fission as a stop gap to fusion. I also think the scale of nuclear waste is vastly over estimated by the general populace.
Generally, it produces very little waste in terms of spent fuel[1] and much of that can be recycled. That does require building newer, modern reactors though.
> The waste will be around for longer than we are. We have no solution other than 'lock it up'.
This is another thing that people don't really understand. Radioactivity is viewed as a monolith in pop culture. There's a perception that a radioactive thing will kill you in thousands of years. In reality, the length of time that something is dangerous is inverse to how dangerous it is, ie, the longer it's radioactive, the less deadly it is (and vise versa). Plutonium-239, the long term radioactive byproduct (24,000 years) is not that deadly [2] compared to the much more radioactive cesium-137 and strontium-90 which both have a half life of around 30 years [3].

- lwhi 5y agoI think it's the fact that it's a stop gap that worries me the most. Imagine being alive in thousands of years, having to mind the 'very little waste' that stopgap produced. I think I'd consider the generations that produced it pretty negatively.
