Nuclear Power is Not the Answer
An op-ed by Dr. Helen Caldicott
November 2006
George Bush, when visiting the Pennsylvania (US) Limerick nuclear power plant on May 24, 2006 categorically stated “Nuclear power helps us protect the environment.” While it is unclear where the President obtained his scientific and medical expertise, his actual knowledge leaves much to be desired.
Contrary to industry propaganda the energy intensive process used to enrich uranium for nuclear fuel, to construct the reactor and to transport and store the intensely radioactive waste for eons of time, emits global warming gases to the atmosphere. A gas fired plant emits three times more CO2 than a similar sized atomic reactor, but as the supply of usable uranium declines over several decades, a nuclear plant will generate as much CO2 as the gas fired generator. Nuclear power therefore contributes substantially to global warming. If all electricity today was generated with nuclear power only nine years supply usable uranium is available. It is therefore a finite commodity like oil.
Wall Street and Standard & Poors are extremely reluctant to invest in nuclear power having been severely burnt in the 1970s and 80s when Three Mile Island and Chernobyl caused the cost of nuclear reactors to soar.
The 2005 energy bill allocated a massive $13 billion to this inefficient dangerous industry. A meltdown induced by terrorism, mechanical or human failure would signal the end of nuclear power and billions of invested dollars will be lost.
David Lochbaum, a nuclear engineer from the Union of Concerned Scientists is not sanguine stating “It is not if but when there is a meltdown” because of lax and inefficient safety procedures overseen by the Nuclear Regulatory Commission at the 103 operating US reactors.
In fact, security has virtually not been tightened at these reactors since 9/11 even though one of the intended targets of the 9/11 terrorists was the Indian Point reactors 35 miles from Manhattan. Up to 43,700 people within 50 miles would succumb to acute radiation sickness over 2 weeks and as many as 518,000 people would die of radiation induced cancer years later according to a study by the Union of Concerned Scientists.
The financial capital of the world would be rendered uninhabitable.
Operating nuclear reactors routinely emit dangerous radioactive materials into the air and water every minute of every day. The noble gases, xenon, krypton and argon are continuously released into the air, where they hover at ground level during meteorological inversion systems, to be inhaled by the surrounding populations. Fat soluble noble gases are readily absorbed through the lung and migrate in the blood to fatty tissues of the abdominal fat pad and upper thighs where they irradiate the reproductive organs with high doses of mutagenic gamma radiation.
Similarly, radioactive hydrogen, or tritium is routinely released into air and water and it also has accidentally leaked into underground water at Indian Point, at the Braidwood, Byron and Dresden reactors near Chicago and the Palo Verde reactor in Arizona. Tritium is a potent carcinogen in animal studies and causes congenital defects. Absorbed readily through the skin, it also enters the body through the gut and lung. With a half life of 12.1 years it is radioactive for over 100 years. People living near nuclear power plants are therefore continually at risk.
But more is at stake. 30 tons of highly carcinogenic nuclear waste is manufactured yearly in each reactor. Nuclear waste is extremely radioactive and so hot that it must be continually cooled for decades, in what euphemistically are called “swimming pools” adjacent to the reactors. A terrorist attack on a swimming pool containing 10 to 30 times more radiation than the reactor could release massive quantities of radiation which would devastate surrounding communities and agricultural areas for ever.
Nuclear waste must be isolated from the environment for at least 250,000 years, a physical and scientific impossibility. In many areas in the US including Hanford WA, Savannah River NC, West Valley NY, radioactive isotopes seep and leak into the environment, where they concentrate at each step of the food chain. Odorless, tasteless and invisible they enter the human body, and migrate to specific organs where they irradiate and mutate surrounding cells for many years. The incubation time for cancer is long – 5 to 60 years, hence the delay in exposing the medical dangers of nuclear power.
Over time however nuclear waste will induce epidemics of cancer, leukemia and genetic disease in all future generations.
The medical dictum states if a disease is incurable the only recourse is prevention.
While nuclear power is a transient generator of electricity its actual legacy is and will be medically catastrophic.

Nuclear Power is the Problem, Not a Solution
by Helen Caldicott
Published on Friday, April 15, 2005 by the Australian
There is a huge propaganda push by the nuclear industry to justify nuclear power as a panacea for the reduction of global-warming gases.
In fact Leslie Kemeny on these pages two weeks ago (HES, March 30) suggested that courses on nuclear science and engineering be included in tertiary level institutions in Australia. I agree. 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. 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 2000 large, 1000-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 $US 560 billion ($726 billion), but the industry pays only $US 9.1 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 $US 33 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 US, 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 50per cent of global warming. Also, this enrichment facility and another at Portsmouth, Ohio, release from leaky pipes 93 per cent of the chlorofluorocarbon 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 power stations. 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 and if inhaled by persons living near a nuclear reactor, are absorbed through the lungs, migrating to the fatty tissues of the body, including the abdominal fat pad and upper thighs, near the reproductive organs. These radioactive elements, which emit high-energy gamma radiation, can mutate the genes in the eggs and sperm and cause genetic disease.
Tritium, another biologically significant gas, is also routinely emitted from nuclear reactors. Tritium is composed of three atoms of hydrogen, which combine with oxygen, forming radioactive water, which is absorbed through the skin, lungs and digestive system. It is incorporated into the DNA molecule, where it is mutagenic.
The dire subject of massive quantities of radioactive waste accruing at the 442 nuclear reactors across the world is also rarely, if ever, addressed by the nuclear industry. Each typical 1000-megawatt nuclear reactor manufactures 33tonnes of thermally hot, intensely radioactive waste per year.
Already more than 80,000 tonnes of highly radioactive waste sits in cooling pools next to the 103 US nuclear power plants, awaiting transportation to a storage facility yet to be found. This dangerous material will be an attractive target for terrorist sabotage as it travels through 39 states on roads and railway lines for the next 25 years.
But the long-term storage of radioactive waste continues to pose a problem. The US Congress in 1987 chose Yucca Mountain in Nevada, 150 km northwest of Las Vegas, as a repository for America's high-level waste. But Yucca Mountain has subsequently been found to be unsuitable for the long-term storage of high-level waste because it is a volcanic mountain made of permeable pumice stone and it is transected by 32 earthquake faults. Last week a congressional committee discovered fabricated data about water infiltration and cask corrosion in Yucca Mountain that had been produced by personnel in the US Geological Survey. These startling revelations, according to most experts, have almost disqualified Yucca Mountain as a waste repository, meaning that the US now has nowhere to deposit its expanding nuclear waste inventory.
To make matters worse, a study released last week by the National Academy of Sciences shows that the cooling pools at nuclear reactors, which store 10 to 30 times more radioactive material than that contained in the reactor core, are subject to catastrophic attacks by terrorists, which could unleash an inferno and release massive quantities of deadly radiation -- significantly worse than the radiation released by Chernobyl, according to some scientists.
This vulnerable high-level nuclear waste contained in the cooling pools at 103 nuclear power plants in the US includes hundreds of radioactive elements that have different biological impacts in the human body, the most important being cancer and genetic diseases.
The incubation time for cancer is five to 50 years following exposure to radiation. It is important to note that children, old people and immuno-compromised individuals are many times more sensitive to the malignant effects of radiation than other people.
I will describe four of the most dangerous elements made in nuclear power plants.
Iodine 131, which was released at the nuclear accidents at Sellafield in Britain, Chernobyl in Ukraine and Three Mile Island in the US, is radioactive for only six weeks and it bio-concentrates in leafy vegetables and milk. When it enters the human body via the gut and the lung, it migrates to the thyroid gland in the neck, where it can later induce thyroid cancer. In Belarus more than 2000 children have had their thyroids removed for thyroid cancer, a situation never before recorded in pediatric literature.
Strontium 90 lasts for 600 years. As a calcium analogue, it concentrates in cow and goat milk. It accumulates in the human breast during lactation, and in bone, where it can later induce breast cancer, bone cancer and leukemia.
Cesium 137, which also lasts for 600 years, concentrates in the food chain, particularly meat. On entering the human body, it locates in muscle, where it can induce a malignant muscle cancer called a sarcoma.
Plutonium 239, one of the most dangerous elements known to humans, is so toxic that one-millionth of a gram is carcinogenic. More than 200kg is made annually in each 1000-megawatt nuclear power plant. Plutonium is handled like iron in the body, and is therefore stored in the liver, where it causes liver cancer, and in the bone, where it can induce bone cancer and blood malignancies. On inhalation it causes lung cancer. It also crosses the placenta, where, like the drug thalidomide, it can cause severe congenital deformities. Plutonium has a predisposition for the testicle, where it can cause testicular cancer and induce genetic diseases in future generations. Plutonium lasts for 500,000 years, living on to induce cancer and genetic diseases in future generations of plants, animals and humans.
Plutonium is also the fuel for nuclear weapons -- only 5 kg is necessary to make a bomb and each reactor makes more than 200kg per year.
Therefore any country with a nuclear power plant can theoretically manufacture 40 bombs a year.
Because nuclear power leaves a toxic legacy to all future generations, because it produces global warming gases, because it is far more expensive than any other form of electricity generation, and because it can trigger proliferation of nuclear weapons, these topics need urgently to be introduced into the tertiary educational system of Australia, which is host to 30 per cent to 40 per cent of the world's richest uranium.
