"The Dark Side" of nuclear power
Nuclear Power Isn't Clean; It's Dangerous - and Uneconomic
By Dr. Helen Caldicott
Among the many departures from the truth by opponents of the Kyoto
protocol, one of the most invidious is that nuclear power is "clean" and,
therefore, the answer to global warming. However, the cleanliness of
nuclear power is nonsense. Not only does it contaminate the planet with
long-lived radioactive waste, it significantly contributes to global
warming.
While it is claimed that there is little or no fossil fuel used in
producing nuclear power, the reality is that enormous quantities of fossil
fuel are used to mine, mill and enrich the uranium needed to fuel a nuclear
power plant, as well as to construct the enormous concrete reactor itself.
Indeed, a nuclear power plant must operate for 18 years before producing one
net calorie of energy. (During the 1970s the United States deployed seven
1,000-megawatt coal-fired plants to enrich its uranium, and it is still using
coal to enrich much of the world's uranium.) So, to recoup the equivalent of
the amount of fossil fuel used in preparation and construction before the
first switch is thrown to initiate nuclear fission, the plant must operate for
almost two decades.
But that is not the end of fossil fuel use because disassembling nuclear
plants at the end of their 30- to 40-year operating life will require yet more
vast quantities of energy.
Taking apart, piece by radioactive piece, a nuclear
reactor and its surrounding infrastructure is a massive operation: Imagine,
for example, the amount of petrol, diesel, and electricity that would be used
if the Sydney Opera House were to be dismantled. That's the scale we're
talking about. And that is not the end of fossil use because much will also be
required for the final transport and longterm storage of nuclear waste
generated by every reactor.
From a medical perspective, nuclear waste threatens global health. The
toxicity of many elements in this radioactive mess is long-lived. Strontium
90, for example, is tasteless, odorless, and invisible and remains radioactive
for 600 years. Concentrating in the food chain, it emulates the mineral
calcium. Contaminated milk enters the body, where strontium 90 concentrates in
bones and lactating breasts later to cause bone cancer, leukemia, and breast
cancer.
Babies and children are 10 to 20 times more susceptible to the
carcinogenic effects of radiation than adults.
Plutonium, the most significant element in nuclear waste, is so carcinogenic
that hypothetically half a kilo evenly distributed could cause cancer in
everyone on Earth. Lasting for half a million years, it enters the body
through the lungs where it is known to cause cancer. It mimics iron in the
body, migrating to bones, where it can induce bone cancer or leukemia, and to
the liver, where it can cause primary liver cancer. It crosses the placenta
into the embryo and, like the drug thalidomide, causes gross birth
deformities.
Finally, plutonium has a predilection for the testicles, where it
induces genetic mutations in the sperm of humans and other animals that are
passed on from generation to generation.
Significantly, five kilos of plutonium is fuel for a nuclear weapon. Thus
far, nuclear power has generated about 1,139 tons of plutonium. So, nuclear
power adds to global warming, increases the burden of radioactive materials
in the ecosphere and threatens to contribute to nuclear proliferation.
No
doubt the Australian government is keen to assist the uranium industry, but
the immorality of its position is unforgivable.
