A Close Look At A Pronuclear “Environmentalist” By Jim Harding
It’s important to know “both sides” of the nuclear waste controversy now that Saskatchewan is being targeted as a nuclear dump. Even if you are skeptical of industry claims that a nuclear waste solution “is in the works”, and see this as a ploy to get more nuclear power plants approved, there’s lots to learn about the nuclear worldview.
Bruno Comby of the French-based “Environmentalist for Nuclear Energy” argues that “nuclear waste has undeniable environmental benefits”. Comby lists three benefits: its “small amount”, it not being “disposed of in the biosphere” and it being “almost totally confined.” He claims that “reprocessed radioactive waste” can be decreased “to the natural level of radioactivity of the original ore after only 5,000 years”, and that “safe, simply and efficient solutions exist to make nuclear waste inert” and to isolate it “from the biosphere until it is no longer toxic”. Finally he claims that a naturally-occurring nuclear reaction 2 billion years ago at Okla, Gabon shows that “waste, after being left unconfined…has not migrated more than three meters.” He concludes the nuclear waste issue is “technically and ecologically solved by a combination of reprocessing technology, vitrification and deep geological disposal.”
This is quite a mouthful. If it’s this “pat” then why, nearly 70 years after the first atom was split, are governments struggling with what to do with nuclear wastes? Comby’s argument is constructed to make real problems disappear. Notice his phrase “after only 5,000 years”, as though it would be acceptable to continue to create high-level wastes threatening environmental health for 50 generations. (It’s actually many more generations when you consider that plutonium has a half-life of 26,000 years.) He claims that because it takes a smaller quantity of uranium than oil to produce the same amount of energy, nuclear wastes are less problematic. But he completely ignores the build-up of long-lived radioactive uranium tailings, which are part of the nuclear waste stream; there are already more than 200 million tons of such tailings in Canada. Comby trivializes the toxicity of spent fuel, claiming that once plutonium is “reprocessed and recycled” as fuel for new reactors the remaining waste “is totally isolated from the environment”. Furthermore, Comby completely ignores the increased dangers of proliferation from plutonium becoming more available.
MORE DISINFORMATION
Comby states that over time nuclear wastes “…are only weakly radioactive. And these…are alpha-ray emitters from which we can easily protect ourselves.” Actually alpha radiation is highly mobile and much more dangerous than previously thought, and is highly carcinogenic if breathed and imbedded in our lungs. Radon gas, which after smoking is the greatest cause of lung cancer worldwide, is an alpha-emitter. But Comby tries to minimize the dangers from nuclear waste build-up by focusing on the dangers of other energy systems. He quotes pronuclear “gaia” theorist James Lovelock that “there is at present no other safe, practical and economic substitute for … burning carbon fuels.” Lovelock said this in 2003, when the global shift to renewables was already underway. By 2005 electricity from renewables surpassed that from nuclear power worldwide, and the gap keeps growing.
