You just conveniently leave out the minor detail that Germany buys a lot of power from France, which IIRC gets around 70% of their power from nuke stations.Some one needs to inform Germany of this. It seems they mistakingly invested in the wrong sort of Power.
Germany's industrial scale is far superior to South Africa's their requirements for power sources far exceeds the needs of South Africa at present, it doesn't even have access to as much ocean as South Africa, and yet it seems to function well with Windmill power and similar sources other than Nuclear power.
The risks associated with Nuclear power can't be managed, since it's not a very predictable source of Power. And the damage can't be minimized, Look at Chernobyl as an example. Russia has far more knowledge in the Nuclear science than South Africa, it has the knowledge and yet still unpredictable events occured. It is not something you can "manage" 100% because it's not that transparent.
