Nuclear must form part of SA’s energy mix to meet growing demand 28th JANUARY 2016

Nuclear must form part of SA’s energy mix to meet growing demand 28th JANUARY 2016There is currently a heated debate in the public discourse about nuclear proliferation and government’s announcement that it will proceed with a nuclear build programme. Media coverage about whether nuclear power is the right solution for South Africa is extensive.

Is nuclear power the right solution for South Africa? According to some nuclear industry experts, this is the wrong question to ask. Knox Msebenzi, managing director for the Nuclear Industry Association of South Africa (NIASA) says, “Nobody in nuclear is saying that we should only be focusing on nuclear; we are saying that South Africa needs an energy mix where nuclear forms part of that mix. In that diversified portfolio of energy assets, 17.8GW has been allocated to renewables and only 9.6GW will be allocated to nuclear. We are saying that South Africa needs an optimum mix and we must not put all our eggs into one basket.”

Nuclear power development brings with it the opportunity for South Africa to become skilled and competent as a nation in certain technological developments that aren’t found with other forms of energy. Spinoff benefits to having a thriving nuclear industry include the opportunity to increase the already successful nuclear medicines industry. The treatment of cancer and the training and skilling of nuclear engineers and  scientists are major areas to benefit from this.  

Another benefit of using nuclear power is that, unlike renewables, nuclear power is reliable and can be dispersed no matter what the weather conditions. It can provide base-load power to the grid, where renewables are far less reliable in terms of output.

“Coal provides base-load power but it has the disadvantage of high carbon emissions. Gas also provides base load power but our domestic supplies of it are not yet exploited economically. If one considers the cost of fuel required to produce power; gas is the most expensive, followed by coal then nuclear. Per KW hour generated, the component of fuel to get a unit of power is a lot higher than in the case of nuclear,” says Msebenzi.

Msebenzi agrees that all technologies have potential risks. Safety is therefore paramount. “The National Nuclear Regulator is a very active and robust regulator. The safety of South Africa’s nuclear power plants is governed by legislation, which is governed by the nuclear regulator. Safety comes first and we cannot let the fears of what happened elsewhere, brought on by a tsunami, stop us from advancing as a nation, and providing our people with electricity,” says Msebenzi.

South Africa is sometimes compared to Europe when it comes to questions about why a nuclear build programme has been chosen. “But South Africa cannot compare itself to Europe’s economies that are highly industrialised and have 100% electricity penetration, some of whom have taken political decisions to decommission their nuclear power plants. Our economic structure and needs are entirely different and we need access to large amounts of base-load power to boost our economy.” Read More....
