Decisions on the future energy mix for South Africa need to be forward looking, not backward looking. So affirmed EE Publishers MD Chris Yelland in his keynote address to the National Nuclear Regulator’s second Nuclear Regulatory Information Conference on Wednesday. "Nuclear power in South Africa was constructed in the 1980s and has served South Africa well for the past three decades," he said. It was the cheapest electricity source in the country until a decade ago. But that was no longer the case, he stated. Nuclear power would now be more expensive than new coal power, or gas generation or renewable energy sources.
