This comment is so incorrect it is laughable.
1. The nuclear waste problem has been "solved" scientifically since the beginning.  Remember, safe and as productive as they are, current reactor designs are inefficient users of their fuel (using at best about 2% of the available fuel).  Some argue that we should never have settled on the current designs, there being better designs (which consume all their fuel leaving tiny amounts of easily handled true waste) - but the history of nuclear power was that the designs which worked on submarines (and later other warships) were simply re-purposed for commercial use.  Not solved? In the minds of the ignorant perhaps but not to nuclear scientists.
2. Dangerous? Nuclear power is the safest source of electricity.

3. The people of SA will not "inevitably" be exposed to waste.  Nuclear professionals go to great lengths to ensure safe storage!
