This was a well balanced document which went into some detail, and proposed various decommissioning strategies. It posed 10 questions which covered liability and security for decommissioning costs, strategies, and research needed.
The actual costs of decommissioning the Koeberg Nuclear Power Station, including final disposal of the spent fuel (so far over 1.5 million kilograms), are unknown. If South Africa had followed the Swedish model with a levy on nuclear power Eskom should have accumulated a fund of about R170bn by now. Instead, Eskom is R450bn in debt. Continue reading →
It has long been suspected that the only motivation behind pushing for nuclear power in South Africa has been corruption via State Capture, coming from then President Jacob Zuma. Details of this are emerging at the Zondo commission into State Capture where it has been testified that a Minister of Finance was fired specifically because he would not ignore the realities of the cost of nuclear power, and so refused tos sign off on the nuclear deal.
Despite this, and despite Zuma being removed from office, there are disturbing signs that there are still those in positions of power who are pushing for taxpayers’ money to be given to the nuclear industry.
The Koeberg nuclear plant near Cape Town requires about thirty tons of uranium fuel per year. Unlike a fuel such as coal, this uranium is not burnt up. It undergoes a nuclear reaction, which transforms it into other elements, some of which are highly radioactive. Burning or any other chemical process does not reduce the radioactivity.
That means that over thirty tons of spent nuclear fuel (SNF) are removed from the reactors each year. So far over a million kilograms of this SNF (over 2000 fuel elements) have accumulated since Koeberg began operating in 1984.
