Why can't they just dig a hole? Unless they are Japan and everything is inhabited by people, surely they can find a backwards part where they can dispose of the waste.Thus far? Yes. But that's why we need to invest more into research for nuclear power. At some point, it should be cheaper, safer, and less expensive than anything else with the right amount of research and thought put into it.
And yeah, this:
Also plays into how expensive it is. That and not every country has a good place for nuclear waste disposal like the US and Russia do.
I'm very sure that fusion power will be the future solution. We just have to get by until it is perfected.
