A series of lectures by Dr. James Conca, a geoscientist with degrees from Cal-Tech, formerly of NASA, and Los Alamos and Pacific Northwest National Labs, explains the what and the why behind used nuclear fuel and how it is stored. Dr. Conca is also a member of the Advisory Group of the Uranium (Nuclear & REE) Committee of the Energy Minerals Division (AAPG). This Committee provides input to the members of the American Association of Petroleum Geologists (AAPG) and to the general public on the nature and availability of nuclear fuel and on the status of nuclear power in the U.S. and around the world.
