During 2009, nuclear power plants, with a capacity of 370 GWe, will produce roughly 14% of the world-wide electric energy. About 65,000 tons of natural uranium equivalent are required to operate these reactors. For the last 15 years, only 2/3 of this fuel has on average been provided by uranium mines, whereas 1/3 has come from secondary resources. According to the International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency (NEA) of the Organization for Economic Co-operation and Development (OECD), the secondary uranium resources will be essentially exhausted during the next 5-10 years. In this paper, the situation concerning the secondary resources at the beginning of the year 2009 is presented. The data used are from the IAEA/NEA 2007 Red Book, "Uranium Resources, Production and Demand," and from the World Nuclear Association (WNA).

Our analysis shows that, at the beginning of 2009, the remaining world-wide civilian uranium stocks amount to roughly 50,000 tons. With the almost inevitable yearly draw-down of 10,000 tons, these civilian stocks will be essentially exhausted within the next 5 years. This coincides roughly with the year 2013, when the annual delivery of 10,000 tons of natural uranium equivalent from Russian military stocks to the USA will end. As the majority of the remaining civilian stocks, about 30,000 tons, are believed to be under the control of the US government and American companies, it seems rather unlikely that the USA will share their own strategic uranium reserves with other large nuclear energy users. In summary, all data indicate that a uranium supply shortage in many OECD countries can only be avoided, if the remaining military uranium stocks from Russia and the USA, estimated to be roughly 500,000 tons, are made available to the other countries.
