With the rising bulk energy consumption and the CO2 problem, nuclear plants appear once again to be a feasible long term source of (industrial) energy.
However a big show stopper is the problem with the radioactive waste which we have to store and isolate possibly for millions of years. As of 2010, there must have been 250 kt of it globally. It might get better if fusion energy becomes largely available, but also in this case you will have to deal with "removable parts'" remaining for 200 years or so.
Given launch prices will become cheap, who knows, maybe one day it might become economically feasible to transport radioactive waste to space where it can be put on say Venus or maybe better in the Sun (given acceptable launch safety levels can be guaranteed!). For sure this is an economic equation where however you make the case against those millions of years mentioned above.
Now my question: is there any scientific research/concepts for that? Is there an estimation of how low the launch price must become to make this topic less of science fiction babble? (Who knows maybe after all, nuclear plants plus space waste dump is really nonsense as compared to orbital solar cells plus microwave energy downstream)
