SA’s long-term nuclear plan no solution to country’s short-term energy needs
Talking millions and billions
However, he says that nuclear power is not economically viable due to high costs needed to construct and maintain plants. “The cost to build a nuclear power station varies in each country. In the United States for example, a nuclear reactor could cost around $10 billion and repairs can also amount to millions of dollars. At the Palo Verde Nuclear Generating Station in Arizona in the US, last year, a leak inside the reactor cost $10 million to $15 million to repair. Solar farms on the other hand, are far more economical as the cost to build ranges between $300 million and $500 million and all that is needed is a large piece of land which receives a vast amount sunlight.”
Furthermore, Chien says that the running costs of electricity generated by a nuclear power plant are far higher than electricity generated from photovoltaic solar energy, as nuclear power plants run throughout the day and night, and according to the Brookings Institution, an American research NGO, they are 75% more expensive to build and run per MW of capacity than a solar-power plant.
Therefore continuing to operate nuclear plants prevents the large-scale integration of renewable energy into the electricity grid.” Chien refers to research conducted by Greenpeace, which states that nuclear also channels investment away from renewables where investment can make a difference in fighting climate change and that renewables can replace several times more of the carbon that is leading to climate change – for the same cost as nuclear and at a far faster pace.
Health and environmental risks
Chien adds that the health and environmental risks associated with nuclear power are also extremely high, especially for those who work in and live in close proximity to plants. “Nuclear power produces toxic waste which can be detrimental to people’s health, as well as the environment. Furthermore, the risk of a nuclear accident like that of the Fukushima meltdown exists and it is crucial to consider because of the effects, including increased levels of radiation in the area and contaminated food and water.”
“An indication that South Africa is heading in the right direction to overcome the energy crisis by means of an environmentally friendly, safer and more economical way, includes the rollout of Kalkbult solar plant in the Northern Cape, a Renewable Energy Independent Power Producer Procurement Programme project, which can already produce enough electricity to be consumed by approximately 33 000 households, lessening the carbon footprint in the area,”
