Nuclear waste is a problem for the most like any other. Given enough investment it can be solved, and no I'm not talking about finding better ways to store it. China has made major advances in this regard, their newest reactors generate waste that is much less long-lived (hundreds rather than tens of thousands of years), and they can reduce the volume of that waste through recycling.
I'm not saying nuclear waste is not a hard problem to solve, it is and we must be careful as a society to make sure it is managed well. In the meantime, we have a climate catastrophe which is much more pressing. Coal plants, which provide base-load electricity, are a prime target for conversion to nuclear, because their steam turbines can be reused. This could decarbonize a large part of the electricity mix of many countries.
The sugar could kill you in the long term, but I think here it's the caffeine you should worry about.
