Future Supply of, and Demand for, Titanium, Copper and Leadby L. K. Grover, AECL Research, Pinawa, Canada,
Abstract: A literature survey has been conducted to assess the future world supply of, and demand for, titanium, copper and lead. These metals are candidates for the fabrication of containers for the immobilization and disposal of Canada's nuclear used-fuel in an underground disposal vault at a Used-Fuel Disposal Centre. The Centre is assumed to begin operation by the year 2020 and continue for about 40 years. The survey has shown that the world has abundant supplies of titanium minerals (mostly in the form of ilmenite), which are expected to last up to at least 2110. However, for copper and lead, the balance between supply and demand may warrant increased monitoring beyond the year 2000. A number of factors that can influence supply and demand are discussed.
