"Known resources" is always a misleading thing. Time and again we used this logic and concluded that the world has only 20 years left of oil, for example. Finding and proving reserves is costly. People don't just randomly decide to invest money to find new resources of Uranium. If there are 8 million tons of economically recoverable Uranium, and the world consumes less than 80k tons per year, that covers us for 100 years. If we were to double the uranium use for whatever reason, mining companies would invest more money into exploration, and the proven reserves will increase by a factor of 2. We are not going to run out of Uranium under any scenario in the next few hundred years.
