They should focus research on thorium reactors as they are supposedly cleaner than what we have today, and afaik you can actually use the fuel waste again and again, so it drastically reduces the problem of nuclear waste and what to do with it.

The promise of thorium is that it requires external energy to be added to maintain the reaction. The theory is that it is safer because of this as it's far less likely that you get a runaway or out-of-control reaction.
The reality is more complex [1].
Molten salt reactors are another active area of research but they have been for decades as well.
