Uran-ressourcer:
Global uranium resources are more than adequate to meet projected requirements, according to the latest edition of a world reference guide on uranium resources published just recently.
Uranium 2005: Resources, Production and Demand - also called the "Red Book" - estimates the total identified amount of conventional uranium stock, which can be mined for less than USD 130 per kg, to be about 4.7 million tonnes. Based on the 2004 nuclear electricity generation rate of demand the amount is sufficient for 85 years, the study states. Fast reactor technology would lengthen this period to over 2500 years.
However, world uranium resources in total are considered to be much higher. Based on geological evidence and knowledge of uranium in phosphates the study considers more than 35 million tonnes is available for exploitation. kilde: IAEA
