Our Finite World

Posted on July 5, 2011- Will uranium supply be adequate for planned nuclear electricity? This question has seen sharply differing views. The purpose of this post is to give an update, showing where we are now.

The supply situation is recently looking better, partly because…Learn more>>   ourfiniteworld.com

How Much Longer Will World Reserves Of The Nuclear Fuel Uranium Last

by Jan Oliver Lofken for DLR,  Berlin, Germany (SPX) Nov 03, 2010

As controversial as nuclear power is, with its still unresolved risks, waste storage problems and high capital costs, it currently meets about 14 percent of global electrical power demand through 430 power stations.

However, as is the case with crude oil, coal or natural gas, reserves of uranium 235 – the fuel used in atomic power stations – are finite, meaning…Learn More>>    nuclearpowerdaily.com

 

WHERE IS URANIUM FOUND AND HOW IS IT MINED?

Mining and Processing Nuclear Fuels- cameco.com

Uranium Overview-   Uranium is a silvery-white metal, roughly 70% denser than lead and is the only naturally-occurring fissile element on earth. Uranium is more common than tin, about 40 times more common than silver and 500 times more common than gold. It’s found in very low concentrations almost everywhere on earth in soil, rocks, water and even in your own back yard….Learn more>>  

 

Principles of Nuclear Power 

Uranium is one of the least plentiful of minerals—making up only two parts per million in the earth’s crust—but because of its radioactivity it is a plentiful supply of energy. One pound of uranium has as much energy as three million pounds of coal…Learn more>>     ucsusa.org

Uranium — Where Is It Found?

By: Dana S. Ulmer-Scholle

Uranium is a naturally occurring element that has the highest atomic weight (~238 g/mole) and is slightly radioactive. It can be found in minute quantities in most rocks, soils and waters (normally < 5 ppm), but the real challenge is…Learn more>>      geoinfo.nmt.edu
