Contrary to popular conception, nuclear does need to be very expensive and is indeed less expensive than the much hyped wind and solar, when you take into account that you need back-up power for intermittent sources of power. In contrast to the USA and France, nuclear projects in China, South Korea and Russia is generally on time and on budget. Nuclear is by far the best option for South Africa to replace the aging and polluting coal plants, most of them rapidly approaching end of life. More than 6GW of old plants should have been closed already, and the big six stations, like Duvha, Lethabo etc, will also reach end of life relatively soon. We should start nuclear procurement as soon as possible to avoid running out of power, as in 2008.
