2008 Feb: Overview of the containers used and the methods employed to move radioactive material. Millions of radioactive items are shipped routinely by road, rail, and ship. Highly radioactive materials such as used fission fuel is carried in special containers. There has never been an accident that caused any of these containers to release anything. Fission fuel is extremely compact, which reduces the environmental impact associated with moving fuel to its point of use. Moving coal and oil is much more damaging and presents a much high risk for significant harm. Radioactive material is moved in Type A, B, or C containers. Type A is used for material that is only weakly radioactive. Type B is used for highly active material such as spent fuel. Type C is used for weapons grade material. The type B and C containers are indestructable and include radio beacons that make them findable.

M. Brown - 2008 Jan 14: This document provides definitions and examples related to reliability, and shows the calculations used to quantify the reliability CANDU reactors. CANDU reactors have the highest capacity factor of all the sources used to generate electricity in Ontario. The managers of the electricity distribution grid must obtain sufficient electrical power at all times, matching various sources with the fluctuating demand. Opponents of nuclear reactors have claimed that Ontario's reactors are not reliable enough. These claims are contradicted by the records of reactor output.
