>storage's insufficency back then is debatable. Sure the batteries were less volume-efficient but that just means more of them
I don't believe batteries with a good enough cycle lifespan for grid-scale use were commercially feasible back then.
Sure lead-acid could be used, but that lasts only a few hundred cycles.
>Transport of nuclear fuel is needlessly hazardous (great opportunity for theft and misuse)
Transport is the worst possible time to try to steal nuclear fuel - a whole transport team is ensuring that the fuel isn't stolen.
>as it cannot be found everywhere in sufficient quantities
The ocean is full of Uranium and there's enough coastlines that every country can get it realistically - it's just that ground mining is cheaper.
