Especially after the weekend revelation, I think we can both agree that corruption is at a point where it is almost a given and nuclear procurement would be effected by it. The bigger the deal the bigger the corruption. 
In addition, especially in a country where jobs should be distributed, many smaller projects would be more beneficial and sizing could still be changed, rather than committing trillions to a single project that will take 10 years. At the speed energy research is at, we will almost certainly face better alternatives, and find efficient ways to store energy. Who knows, maybe even safer nuclear options might become available. But right now, expecting anything at ESKOM to be properly managed is a joke.
So, let us scale our electric needs with other sources, on smaller scales, enable more South Africans and it's economy to be involved (as opposed to handing most of it to the Russians), instead of creating another avenue of blatant corruption.
