In the end, though, there's little doubt that Seaborg's table of rows and turrets, with the lanthanides and actinides like moats along the bottom, will dominate chemistry classes for generations to come.

The design criteria include the minimisation of waste and better management of natural resources, while four of the six selected systems are 'fast reactors' associated with a closed cycle to burn long-lived actinides. Fast reactors with depleted uranium will produce new fissile material."
These materials, formed during irradiation of fuel in the reactors, are collectively known as the minor actinides, to distinguish them from the larger quantities of uranium and plutonium also present in the fuel.
