Just to be clear, I wanted to include as wide a spectra for answers as possible, to avoid having to put in more answers later on. A vote for PES is a vote for EPP! A vote for EPP is a vote for PES! Support the coalition, vote EPP-PES in 2009!
Of course, newer reactors will be like the EPR: over 1.5 GW, versus 500-800 for many old units in the US for instance. So the total capacity will increase. Uranium consumption will not increase that much, because newer reactors have better yields, better breeding ratios, they're all designed to run on MOX, etc...
It is also because of all these reasons that I don't believe seriously that any U shortage will happen this century. I also believe nukes won't help much those who don't already have them running today (like France). Pierre
