Il n'y a rien de "vert" dans l'énergie nucléaire

La pollution nucléaire découlant des centrales nucléaires ainsi que des déchets nucléaires s'accumule et il n'y a aucun moyen de disposer de ces polluants. 

La radioactivité est capable de modifier la structure chimique et génétique des matériaux et des humains qui y sont exposés. 

Certains déchets nucléaires sont relâchés dans notre environnement, d'autres sont recyclés en bombes et en munitions pour l'armée américaine. 

La conférence des Nations Unies sur les changements climatiques en 2000 a désigné l'énergie nucléaire comme une technologie polluante, dangereuse et non nécessaire. 

En plus d'être inefficace, cette énergie produit des gaz à effet de serre.

No "green" hiding behind nuclear energy

Beth McLaughlin

Nuclear pollution includes regular emissions from nuclear plants and nuclear waste, accumulating inside and outside nuclear plants. There are 28,000 tons of waste sitting in metal containers encased in cement outside of Point Lepreau.

countless centuries."
Gordon Edwards


Nuclear pollution also includes the radiated coolant, water which flows around the hot fuel rods. The fuel rods, once spent (but still hot and deadly) are then mechanically transferred to storage pools inside the plant to cool off for 10-20 years before they can be stored for 40 to 50 years in the metal and cement containers. Sometimes we read about leaks of radiated coolant from a plant - this radiated liquid runs into a lake, river or the ocean and is in our atmosphere for thousands of years.

Though the nuclear industry claims that nuclear energy is clean, in fact, the nuclear plant itself becomes unusable with time. Most of the plant will become radioactive and have to be dismantled and isolated as radioactive waste. There is NO safe way of disposing of radioactive materials.

The violence of the nuclear chain reaction is such that it can also yield what are called activation products, i.e. it can cause already existing chemicals in air, water or other nearby materials to absorb energy, change their structure slightly and become radioactive.

From the cradle to the…cradle

From the mining of radioactive materials to working in a nuclear plant workers, generally men, are exposed to ionizing radiation which in the long term, will eventually take its toll on their health…and the future generations of his family. There is no safe level of exposure to ionizing radiation and the search for quantifying such a safe level is in vain. A "permissible" level, based on a series of values, is how radiation levels have been established within society.

In 1943, Hermann Müller received a Nobel Prize for his work on the genetic effects of radiation. He demonstrated through his work with fruit flies that ionising radiation affects not only the body which is exposed but also the seed within the body from which the future generations are formed.


"Given what comes out of the tail pipe, it [nuclear energy] has got to be the
dirtiest of all"
Lorne Calvert, Premier of Saskatchewan.


Heavy water coolant

CANDU reactors use deuterium oxide or "heavy water" as both a moderator and a coolant, and effectively "breed" tritium as the nuclear fission process releases free neutrons (i.e. tritium atoms are created when a deuterium atom absorbs an additional neutron).

In Ontario, at the Bruce nuclear complex, tritium is released to the station cooling water effluent stream (Condenser Cooling Water) which discharges into Lake Huron. Tritium can also be released to the air by venting of the plants and incineration of low level waste

Once released to the environment, tritium exposure can occur from a variety of sources, namely via water, air and food; exposure to water-borne releases can occur through the consumption of drinking water supplies or through other water contact (e.g. swimming, bathing, showering).

Depleted uranium

Reprocessed uranium from spent fuel called Depleted Uranium (DU) is being incorporated into bombs and ammunition by the American military. DU was first used in the Persian Gulf war where its effects became public when American soldiers returned home complaining of ill health. Higher incidences of leukemia and blood disorders, among other symptoms, are present in these soldiers.

Today, in Iraq generally and Baghdad in particular, ionizing radiation levels are 1000 to 2000 times higher than background radiation. Information on the incidence of malignancies among children below 15 years of age in Basrah, southern Iraq shows there has been a 100 % rise in the incidence of various forms of leukemia among children in 1999 compared to 1990. The corresponding rise for all malignancies among such children in 1999 compared to 1990 was 242 %.

DU projectiles are internationally banned under the terms of the 1980 Convention on prohibitions or restrictions on the use of certain conventional weapons which may be deemed to be excessively injurious or to have indiscriminate effects.

Nuclear accidents

Chernobyl's meltdown (1986) was the worst accident in the short life of nuclear history (60 years) but there have been many accidents over the past 60 years. Accidents have been documented in research facilities, power plants, bombs and bombers, submarines and ships, nuclear testing facilities and in the processing, storage, shipping and disposal of radioactive materials.

Solution to GHGs or BIG problem In November 2000 the world recognized nuclear power as a dirty, dangerous and unnecessary technology by refusing to give it greenhouse gas credits during the UN Climate Change talks in the Hague. The world dealt nuclear power a further blow when a UN Sustainable Development Conference refused to label nuclear a sustainable technology in April 2001.

So, when someone claims that nuclear power is clean energy, know that nuclear power is not only ineffective at addressing climate change, but when the entire fuel chain is examined, nuclear power is found to be a producer of greenhouse gases. Producing enough nuclear power to make a meaningful reduction in greenhouse gas emissions would cost trillions of dollars, create tens of thousands of tons of lethal high-level radioactive waste, contribute to further proliferation of nuclear weapons materials, result in a Chernobyl-scale accident once every decade or so, and, perhaps most significantly, squander the resources necessary to implement meaningful climate change mitigation policies.
