Argument: Alternative renewables are inefficient for the cost

Nuclear power is the most practical renewable energy source as all the others face major difficulties either in scaling up to provide enough to be a major component of nations energy mix, don't provide energy all the time, the 'base load', or cause other environmental problems. Nuclear is a proven technology with large firms that can build large amounts of nuclear energy generation capacity.

The most efficient source of renewable energy has been hydroelectric power, however, this usually creates more problems than it solves. Building a large dam necessarily floods an enormous region behind the dam which in turn can displace thousands of people. There are also enormous ecological costs to dam building. A classical example is the Aswan dam in Egypt along the Nile. Not only did many thousands lose their homes but the yearly inundation of the Nile, which fertilised the surrounding land for thousands of year, was also stopped; the subsequent silting up of the river destroyed much wildlife1. A similar story of ecological destruction and human homelessness surrounded the more recent Three Gorges dam project in China2.

Wind, tidal, and solar power are all affected by issues of reliability. The tendency of wind power, in particular, to be a volatile source of energy, means that other power sources such as fossil fuel power stations have to make up the shortfall when wind levels drop. Tidal power technology is still in at an early stage and may take years to become profitable. It also has the potential to cause environmental problems in the marine environment. For a large area of the European Union, there is not the potential to exploit solar power as there are not enough hours of sunlight.

"Wind and solar power have their place, but because they are intermittent and unpredictable they simply can't replace big baseload plants such as coal, nuclear and hydroelectric. Natural gas, a fossil fuel, is too expensive already, and its price is too volatile to risk building big baseload plants. Given that hydroelectric resources are built pretty much to capacity, nuclear is, by elimination, the only viable substitute for coal. It's that simple."3

Candidate 1: "Nuclear power is no better placed to deliver the amount of energy required. There is an unrealistic focus on nuclear power as a magical solution to climate change. Despite increasing demand the amount of electricity being generated by nuclear is projected to fall not rise. The share of nuclear energy will decrease from 30% to 25% in electricity generation by 2020. According to current projections, the nuclear generation capacity in the EU would fall by as much as 33 GWe by 2020; this fall would mostly have to be met by dirty power plants using gas, or particularly coal [1] .

The focus on nuclear power diverts attention from other renewables. In reality going nuclear would squeeze out renewables. Indeed, the former Secretary of State for Business Patricia Hewitt said in a Commons debate on a 2003 Energy White Paper: 'It would have been foolish to announce …. that we would embark on a new generation of nuclear power stations because that would have guaranteed that we would not make the necessary investment and effort in both energy efficiency and in renewables' [2] .

Candidate 2: "For nuclear power plants any cost figures normally include spent fuel management, plant decommissioning and final waste disposal. These costs, while usually external for other technologies, are internal for nuclear power. Costs are high compared to coal fired generation precisely because the externalities associated with high carbon outputs are not taken into account, whereas similar externalities relating to nuclear generation are. If costs are calculated equivalently to coal power stations then nuclear power is competitive.

Also the cost of construction and decommissioning of nuclear power plants is often overestimated; the French and Swedish nuclear industries estimate decommissioning costs to be just 10 -15 % of the construction costs and budget this into the price charged for electricity1. Nuclear is actually increasing its competitiveness as gas and oil prices rise, new technology makes nuclear power more efficient and construction and decommissioning costs less. An OECD study in 2005 showed nuclear overnight construction costs ranged from US$ 1000/kW in Czech Republic to $2500/kW in Japan, and averaged $1500/kW. Coal plants were costed at $1000-1500/kW, gas plants $500-1000/kW and wind capacity $1000-1500/kW2. The difference, when weighed against nuclear power's other advantages, is thus not that great.

Candidate 3: "There is almost always one renewable resource that a given country can exploit with sufficient investment; tides for islands, the sun for equatorial countries, hot rocks for volcanic regions. Any given country can in principle become self-sufficient in terms of renewable energy. The global distribution of uranium is hugely uneven (much more so than fossil fuels) and the use of nuclear power therefore gives countries with uranium deposits disproportionate economic power. Kazakhstan became the world's number one supplier of uranium in 2009, and other major producers such as Russia, Namibia, Niger and Uzbekistan may not be reliable1. It is far from inconceivable that uranium could be subject to the same kind of monopoly that the OPEC (Organisation of Petroleum Exporting Countries) places on oil.

1 'Kazakhstan plans to become global leader in uranium production by 2009', Silk Road Intelligencer, 23rd July 2008,"
Candidate 4: "The nuclear industry has a shameful safety record and it is haunted by the constant risk of meltdown or explosion. "No reactor in the world is inherently safe. All operational reactors have inherent safety flaws, which cannot be eliminated by safety upgrading. Highly radioactive spent fuel requires constant cooling. If this fails, it could lead to a catastrophic release of radioactivity. They are also highly vulnerable to deliberate acts of sabotage, including terrorist attack"1. Chernobyl and Japan's Fukushima plant has shown the world what happens when cooling systems fail.

The effects on the local people and the environment are devastating. It cannot be a coincidence that the rate of occurrence of certain types of cancer, such as leukaemia, is much higher in the population around nuclear plants. It is perfectly true that modern nuclear reactors are safer but they are not completely safe. It is not worth the risk.

The dumping of nuclear waste also presents a host of problems. The Nuclear Inspectorate in the UK has been very critical of safety standards within the industry; it is too dominated by the profit motive to really care about safety and too shrouded in secrecy to be accountable. According to Agenda 2000: "The problem of nuclear safety in some candidate countries causes serious concerns to the EU... and should be urgently and effectively addressed. It is imperative that solutions, including closure where required, be found to these issues in accordance with the Community nuclear acquis and a "nuclear safety culture" as established in the western world as soon as possible"2.

Candidate 5: "Encouraging the further adoption of nuclear power is against our security interests. The scientific understanding and technology needed to generate nuclear power is the same as that needed to create nuclear weapons, and it is all too easy for rogue states to pretend they are only interested in peaceful uses while secretly pursuing military applications. This is the route India and Israel have followed, and that Iran may well be following at present. The process of enriching uranium to make it into fuel for nuclear power stations can be a step towards further enriching it to make nuclear weapons. Used fuel from nuclear power stations can be separated out to recover any usable elements such as uranium and plutonium through a method called reprocessing. Plutonium is a by-product of the nuclear fuel cycle and can also be used to make nuclear weapons1.

Even if the intentions of foreign governments are good, widespread nuclear power plants are at risk of terrorism, in both the developed and developing world. If a 9/11-style bomb was flown into a nuclear power plant, the potential disaster would be catastrophic. And the more nuclear material is transported around the world, the easier it will be for terrorists to get hold of some in order to make their own nuclear weapons. An atomic bomb might one day be within the reach of some international terrorist groups, but even today a simple "dirty bomb" (in which highly-radioactive materials is blasted over an urban area using conventional explosives) could be deadly to many thousands of people. Encouraging the spread of nuclear technology enables the spread of nuclear weapons.

Candidate 6: "We hear a lot about the depletion of supplies of fossil fuels, however it is not mentioned that there is also a potential problem with the supply of uranium: "There is currently a gap in the amount of uranium being mined and the amount of uranium being consumed," states Nuclear Energy Corporation of South Africa (Necsa) CEO Rob Adam1.

This would potentially be ok if it did not look like we are approaching a uranium peak. The peak in supplies of uranium seems likely to arrive sometime between 2030 and 2040 with uranium being almost totally gone by 2070 or 2120 at the latest. It is the peak that matters, as after this point supply will not be able to keep up with demand. If you take into account that nuclear energy produces 16% of world electricity, and less than 5% primary energy supply, it seems impossible to me for nuclear energy with current technology to ever satisfy a big part of the world's energy demand2. It means that nuclear power is not a sustainable base which we should be looking to be dependent on.

Candidate 7: "Nuclear power plants are not much of an improvement over conventional coal-burning power plants despite claims that nuclear is the 'clean air energy.' Uranium mining, milling, leeching, plant construction and decommissioning all produce substantial amounts of greenhouse gases. Taking into account the carbon-equivalent emissions associated with the entire nuclear life cycle, not just the nuclear fission itself, nuclear plants contribute significantly to climate change and will contribute even more as stockpiles of high grade uranium are depleted1.

Nuclear waste can remain radioactive for thousands of years. It must be stored for all this time away from water into which it can dissolve and far from any tectonic activity. This is virtually impossible and there are serious concerns over the state of waste discarded even a few decades ago. A report by the Environment Agency attacked Britain's disposal system as many containers used to store the waste are made of second-rate materials, are handled carelessly, and are liable to corrode; computer models suggest up to 40% of them could be at risk of being compromised within as little as 200 years2. Tens of thousands of containers of this waste, bound in concrete, are simply being stored above ground, mainly at Sellafield, while the Government and the nuclear industry decide what to do with them. On present plans it is assumed they will remain there for up to another 150 years before being placed in a repository underground, and then another 50 years before it is sealed3. This problem would only be added to if more nuclear power stations were built.

Candidate 8: "Nuclear power is itself inefficient: For every three units of energy produced by the reactor core of a U.S. nuclear power plants, two units are discharged to the environment as waste heat. Nuclear plants are built on the shores of lakes, rivers, and oceans because these bodies provide the large quantities of cooling water needed to handle the waste heat discharge1.

It is perfectly true that alternative energy is not efficient enough to serve the energy needs of the world's population today. However, with investment all these methods could be made efficient enough. Not enough has been done to make use of all the natural energy sources that do not create the kind of damage nuclear power generation causes. We need to develop more efficient ways to capture wind, water and solar power, to explore other options and to reduce the level of power required. This is not an argument for nuclear power but one for greater resources to be put to develop natural energy sources and help protect the planet for future generations.
