An Introduction to Nuclear Power

Abstract

Nuclear power is a controversial form of power generation based on the exploitation of nuclear reactions. Nuclear power plants do not emit carbon dioxide while generating electricity but they do produce radioactive waste that must be disposed of safely. Safety is also a crucial factor because an accident at a nuclear power station can release radioactive material into the environment and this will potentially have devastating consequences. Nuclear power grew out of the nuclear weapons programs of the early and mid-20th century and the technology saw its greatest growth between the beginning of the 1960s and the beginning of the 1980s. In 2013 nuclear power contributed around 11% of global electricity.

Nuclear power is the most controversial of all forms of electricity generation. Evaluating its importance involves weighing political, strategic and, often, emotional considerations alongside the more usual technical, economic, and environmental factors that form the core elements of any power technology debate. To complicate the issue further, partisan views are frequently advanced so that balanced, objective decision-making can be difficult, if not impossible.

From a technological point of view, nuclear power offers a tested method of generating electrical power based on exploitation of the energy released during controlled nuclear reactions. However the byproducts of these nuclear processes are a range of extremely toxic radioactive materials, and the nuclear industry has still to develop widely accepted ways of disposing of this waste in a secure manner. An additional, complicating issue is the ability of nuclear technology to be exploited for weapons production as well as power; the overlap between the two makes it very difficult to separate one from the other.

The other great cause of anxiety is the possibility of a nuclear accident. The consequences of an accident at a nuclear power plant that leads to the release of radioactivity into the environment are potentially much more far-reaching that would be the case with an accident at any other type of power plant. This was dramatically demonstrated by the incident at the Fukushima Daiichi nuclear power plant in Japan following a massive undersea earthquake and tsunami in 2011. Both this and the earlier Chernobyl nuclear plant failure have seriously damaged popular confidence in nuclear power and both have had an influence on government policy in several countries, notably Germany, where nuclear power is being phased out as a result of the 2011 accident.

If these issues weigh negatively in the balance, on the positive side nuclear power does offer a carbon-free means of generating electricity and in a world where the control of carbon emissions has become a major requirement if global warming is to be controlled, nuclear technology potentially offers a part of the solution. The International Energy Agency has identified nuclear power as one of the key technologies that will be needed if the globally agreed target of trying to limit global warming to 2°C is to be achieved.¹ Whether the organization’s optimistic forecasts for nuclear growth are realistic, given both the negative effect of the 2011 accident and the fall in the cost of power from solar and onshore wind power, which has undercut wholesale power prices in Europe, remains to be seen.

The modern nuclear power industry was born out of the nuclear weapons programs that led to the development of the atom bomb during the 1940s. While weaponry was the aim of the research during World War II, power generation quickly became a secondary, peaceful product of the work and programs were started in both the United States and Russia. Electricity production from nuclear power began on a very small scale at an experimental reactor in the United States in 1951 while in Russia a 5-MW plant designed to generate electricity began operating in 1954. This was followed, in 1956, by a 50-MW dual purpose reactor² at Calder Hall, in the United Kingdom, while the French began a nuclear program the same year at Marcoule. The first fully commercial nuclear power plant was built at Shippingport, Pennsylvania, in the United States, and started operating in 1957.

From the late 1950s nuclear generating capacity began to grow rapidly with commercial power plant construction programs in the United States, Russia, the United Kingdom, France, and Canada. Other countries such as Germany, Sweden, and Japan also began to invest in the technology. By the beginning of the 1970s, nuclear power was seen as the great hope for the future of electricity generation. In the United States alone, power companies had ordered over 200 nuclear reactors.

Even as the nuclear power industry was booming, there were concerns about nuclear safety and ...
