It’s clean, it’s safe, it’s the future

Western forces are striking Libya on the pretext of fighting a “tyrant”, once again underscoring that oil is the primary cause of much of the modern world’s conflicts. Iraq was attacked by United States-led forces in 2003 for the same reason and because Saddam Hussein refused to follow the example of many other countries in the region and favor the US and the European Union.
Not many people know that the US Department of Defense consumes close to 500,000 barrels of oil a day. Modern warfare is fuelled by oil, which is needed to keep aircraft, ships, tanks, trucks and other fighting vehicles moving, and to power missiles and rockets.
Since the end of World War II, the US and the European powers have stitched together a network of alliances to ensure cheap and easy access to oil. In countries whose leaderships are not close to them, such as Venezuela, they support regime change, as they did in Iraq – and now want to do in Libya.
And let us not forget the immense damage caused to the environment by fossil fuels, which emit pollutants that in turn cause many diseases and the deaths of millions of people. Yet despite such an abysmal record, the oil lobby in developed countries continues to ensure that the spotlight is trained on the only energy that can become a substitute within a decade, that is, nuclear energy.
After the man-made nuclear disaster at Chernobyl in 1986, several theories were floated about the number of people who died because of radiation and radiation-related diseases. Some estimates put the death toll from radiation-related diseases at more than 175,000, while even the lowest estimates spoke of 10,000.
As US writer Gwyneth Cravens says, the group of 226,000 workers active in cleaning up the Chernobyl facility surroundings “received an average body dose of 1,000 millirems, less than they would have received from nature if they had moved to (the US) northeastern (state of) Washington for a year”. She says that studies conducted on more than 500,000 workers involved in the cleanup “failed to find any correlation between the increased exposure to radiation and a rise in cancer or death rates”. Ten years ago, a United Nations committee concluded that at Chernobyl, “there is no scientific evidence of increases in overall cancer incidence or mortality”.
But thanks to the immense reach of the oil lobby, such facts are kept hidden from the public, which is given daily doses of stories on the “dangers of nuclear power”.
In India, foreign agencies which eager to ensure that the country does not develop into an economic superpower have been known to clandestinely fund protests and agitations against nuclear power and uranium mining. People living around nuclear power facilities – or a newly selected nuclear power plant site – are told that their lives are at risk, and that they should oppose nuclear power plants and uranium mining. India suffers from a serious shortage of uranium because powerful, hostile lobbies prevent the mining of this essential metallic element.
Facts don’t affirm popular belief

Many people are again presenting nuclear power as a solution to the world’s energy demands because of the constraints associated with coal and the fear of oil prices shooting through the roof, and because the reality of global warming has started to hit home.
But can nuclear power provide what we are all looking for: a reliable, affordable, sustainable, secure and now low-carbon source of electricity?
When the full nuclear fuel cycle is considered – not only reactors but also uranium mines and mills, enrichment facilities, spent fuel repositories and decommissioning sites – nuclear power proves to be one of the costliest sources of energy. Nuclear plants are capital intensive and the high capital costs result in higher charges by electricity generators. This either ends up with high costs for customers, or significant government funds being expended on subsidies, or both.
A study of construction costs of nuclear power facilities across five countries has found that quotes by industry were unreliable, conservative and that construction was subject to costly project overruns which sometimes doubled the cost of building the plant.
Since most Asian nuclear programs are new, decommissioning costs for Asian governments are largely unknown. Historical data from the United States and the United Kingdom indicate huge decommissioning costs of $300 million to $5.6 billion per nuclear power facility. Assessment of decommissioning by the US General Accounting Office show that decommissioning costs have exceeded plant revenue by more than $4 billion.
Moreover, nuclear power is reliant on uranium availability and uranium prices, like oil and natural gas, and highly volatile. This means uncertain uranium prices can have a grave impact on plant operating costs. Such price movement is hard to anticipate when some of the countries, responsible for more than 30 percent of the world’s uranium production, are politically unstable.
To plan for long-term energy solutions, fuel availability needs to be assessed beyond 2020, when future plants in Asia will be operational. The International Atomic Energy Agency expects that primary supply of uranium (all newly mined and processed uranium) will meet only 4 to 6 percent of total demand in 2025, and secondary supply (highly enriched uranium, enriched uranium inventories, mixed oxide fuel, reprocessed uranium and depleted uranium tails) will meet 8 to 11 percent of the world demand.
The implication is clear: a huge shortfall is likely to exist between uranium supply and demand. Even on optimistic assumptions of fuel availability, global reserves of uranium will only support a growth in nuclear power of 2 percent and be available for 70 years.
Furthermore, the nuclear fuel cycle involves some of the most dangerous elements known to humankind. These elements include more than 100 dangerous radionuclides and carcinogens such as strontium-90, iodine-131 and cesium-137, which are the same toxins found in the fallout of nuclear weapons.
In addition to questions about the safe handling of such elements, the nuclear fuel cycle presents numerous other environmental risks.
Nuclear energy is highly water intensive. Nuclear plants use 25 to 50 percent more water per unit of electricity generated than fossil fuel plants with equivalent cooling systems. That’s why during periods of drought many nuclear facilities either cannot operate or induce water shortages. The average US plant operating on an open-loop cooling system withdraws 216 million liters of water and consumes 125 millio n liters every day.
