    Flywheel storage is not a serious solution for anything but adding inertia to the grid, where it is sometimes brought up as an expensive solution to the fact that unlike hydro, geothermal, coal, oil, combined cycle, and yes nuclear, solar and wind have no intera because unlike all the previously mentioned modes of generation they have no flywheel built in.

    If energy stoage is a problem for nuclear, than it is literally at least a hundred times larger one for solar. You might need to store a tiny inbalance for nuclear, you need to store the entire grid capacity for the entire night with solar. It also ignores that you can run an entire power grid on nuclear and hydro, we know because entire nations have been actually doing it since the seventies.

    Wind absolutely cannot be built anywhere at grid scale. There are relatively few areas where it is consistent enough to generate a worthwhile output. Solar will output with indirect lighting or when cloudy, but only at a third to a quarter of its direct sunlight output, and it does require both massive tracks of land and along with wind has massive trouble with nimbys blocking new development and the necessary scale up in tranmision lines.

    This is not to say that solar and wind are unworkable obviously, just that they are nither easy nor without major downsides. This is why a well designed grid has a diverse set of sources and doesn’t just rely on uncontrollable sources like solar and wind. Nuclear does a very good job of providing consistent green energy on calm nights and can be built just about anywhere without requiring the large open land of solar or the strong constant breeze of wind.

    Waste really isn’t a serious concern. The vast majority is low level stuff like used clean suits and gloves that are only a problem for decades, and you can glassify or recycle the high level stuff. We just often don’t bother because compared to the massive open pits of toxic chemical waste that will be just as deadly in a trillion years as it is today, and which are created by producing everything from your phone and laptop to solar panels, there just really isn’t enough of it to cause the problems thouse other types of toxic waste do.
