Deep Geological Repositories are best nuclear option

 

RE: Nuclear Burial Site urged (May 24, 2005)

 

Dear Editor,

 

As a proud employee in Canada’s nuclear industry I’d like to clarify several points contained in this article that I feel may not give your readers a reasonable representation of the nuclear fuel disposal issue.

 

While overall the article presented a fair overview of the current situation, the language used to describe the plan was filled with negative connotations.  In particular, the many references to “mausoleum” and “dump” are not adequate to describe Deep Geological Repositories.

 

This terminology creates the impression that nuclear fuel is simply buried underground in a deep hole.  This is most emphatically not the case.  The Canadian repository concept was developed through many decades of study at Atomic Energy of Canada Limited’s Underground Research Laboratory (URL) in Manitoba.  It employs around a dozen layers of engineered defense to protect the fuel from degradation and transportation mechanisms.  This combines with careful site selection to ensure the chances of a harmful release are as near to zero as possible. When considering both technical and social issues these repositories are second to none and the NWMO has made a good choice.

 

 

I also believe that the nature of the used fuel was slightly misrepresented.  It is important to note that the radioactivity of the fuel begins to decrease the second it is removed from the reactor.  While initially it does have the potential to be harmful (yet is not due to the technology and safety measures in place), after 500 years a human could safely work alongside a used CANDU fuel bundle for an entire day.  At this juncture the danger would be from ingesting portions of the fuel.  It is this scenario which a Deep Geological Repository is designed to prevent.

 

No other toxic material has the desirable property of reducing its harmful effects over time.  The hundreds of harmful chemicals used in hundreds of industries every day will be just as dangerous in a million years as they are today.  The difference between many of these chemicals and nuclear fuel is that they are not nearly as strictly regulated and many are being dumped into our water and air as a means of “disposal”.

 

On a final note I take issue with the method used to represent the amount of used fuel that exists.  As was pointed out, the 40 plus years of nuclear power in Canada has produced around 1.9 million fuel bundles.  This certainly sounds impressive but the volume taken up by these bundles is a concept much easier to grasp for the Canadian public.  Put another way Canada’s used fuel from 40 years of operation takes up the same amount of space as the amount of garbage the city of Toronto ships to Michigan every day!  Furthermore this small amount of fuel has generated massive amounts of emissions free electricity that has prevented the release of around a billion tonnes of greenhouse gas and air pollution.  That’s a lot of clean air and that sounds good to me!
