Nuclear Energy Is Not the Energy of the Future

Nuclear Energy Is Not the Energy of the Future

According to Australian-born physician and antinuclear activist Helen Caldicott, the nuclear industry is waging a misleading propaganda campaign to portray nuclear power as a panacea for environmental and energy crises. In the following viewpoint, Caldicott contends that nuclear energy is actually not emission-free, not safe, and not fossil-fuel-free. She also maintains that nuclear power plants are vulnerable to terrorist attack, with potentially catastrophic consequences over and above the risks of radioactive waste. Helen Caldicott is founder and president of the Nuclear Policy Research Institute, which opposes the use of nuclear energy and cofounder of Physicians for Social Responsibility.

There is a huge propaganda push by the nuclear industry to justify nuclear power as a panacea for the reduction of global-warming gases....

But I would suggest that all the relevant facts be taught to students. Mandatory courses in medical schools should embrace the short- and long-term biological, genetic and medical dangers associated with the nuclear fuel cycle. Business students should examine the true costs associated with the production of nuclear power. Engineering students should become familiar with the profound problems associated with the storage of long-lived radioactive waste, the human fallibilities that have created the most serious nuclear accidents in history and the ongoing history of near-misses and near-meltdowns in the industry.

Nuclear Reactors Are Not Practical

At present there are 442 nuclear reactors in operation around the world. If, as the nuclear industry suggests, nuclear power were to replace fossil fuels on a large scale, it would be necessary to build 2,000 large, 1,000-megawatt reactors. Considering that no new nuclear plant has been ordered in the US since 1978, this proposal is less than practical. Furthermore, even if we decided today to replace all fossil-fuel-generated electricity with nuclear power, there would only be enough economically viable uranium to fuel the reactors for three to four years.

The true economies of the nuclear industry are never fully accounted for. The cost of uranium enrichment is subsidised by the US government. The true cost of the industry's liability in the case of an accident in the US is estimated to be $US560 billion, but the industry pays only $US9.1 billion—98 per cent of the insurance liability is covered by the US federal government. The cost of decommissioning all the existing US nuclear reactors is estimated to be $US33 billion. These costs—plus the enormous expense involved in the storage of radioactive waste for a quarter of a million years—are not now included in the economic assessments of nuclear electricity.

It is said that nuclear power is emission-free. The truth is very different.

In the U.S., where much of the world's uranium is enriched, including Australia's, the enrichment facility at Paducah, Kentucky, requires the electrical output of two 1000-megawatt coal-fired plants, which emit large quantities of carbon dioxide, the gas responsible for 50 per cent of global warming.

Also, this enrichment facility and another at Portsmouth, Ohio, release from leaky pipes 93 per cent of the chlorofluorocarbon [CFC] gas emitted yearly in the US. The production and release of CFC gas is now banned internationally by the Montreal Protocol because it is the main culprit responsible for stratospheric ozone depletion. But CFC is also a global warmer, 10,000 to 20,000 times more potent than carbon dioxide.

In fact, the nuclear fuel cycle utilises large quantities of fossil fuel at all of its stages—the mining and milling of uranium, the construction of the nuclear reactor and cooling towers, robotic decommissioning of the intensely radioactive reactor at the end of its 20 to 40-year operating lifetime, and transportation and long-term storage of massive quantities of radioactive waste.

In summary, nuclear power produces, according to a 2004 study by Jan Willem Storm van Leeuwen and Philip Smith, only three times fewer greenhouse gases than modern natural-gas[-fueled] power stations.

Nuclear Power Is Not Clean Power

Contrary to the nuclear industry's propaganda, nuclear power is therefore not green and it is certainly not clean. Nuclear reactors consistently release millions of curies of radioactive isotopes into the air and water each year. These releases are unregulated because the nuclear industry considers these particular radioactive elements to be biologically inconsequential. This is not so.

These unregulated isotopes include the noble gases krypton, xenon and argon, which are fat-soluble
