Is Nuclear Energy Renewable Energy?
In his arguments he includes uranium that could be extracted at a higher cost, uranium from the sea water and also uranium from eroding earth crust by river water. All of those possible uranium resources if used in a breeder reactor would be enough to fuel the earth for another 5 billion years and hence renders nuclear energy as renewable energy.

Uranium mining - Energy Education
Milling produces a uranium oxide concentrate, which is shipped from the mill. In the milling process, uranium is extracted from the crushed and ground-up ore by leaching, in which either a strong acid or a strong alkaline solution is used to dissolve the uranium oxide. The uranium oxide is then precipitated and removed from the solution.

Uranium - an overview | ScienceDirect Topics
Uranium is the fuel most widely used by nuclear plants for nuclear fission. Uranium is considered as a nonrenewable energy source, even though it is a common metal found in rocks worldwide. Nuclear power plants use a certain kind of uranium, referred to as U-235, for fuel because its atoms can be easily split apart.
Uranium - Wikipedia
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table.A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and …
About Uranium - NRCan
The Canadian uranium industry is composed of firms that mine and mill raw uranium ore, refine and convert it into uranium dioxide and uranium hexafluoride, and produce fuel bundles for CANDU nuclear reactors. The key producers in Canada are Cameco Corporation and Orano Canada Inc., which rank among the world's leading uranium suppliers.
