Yes, Thomas mentioned IFR, but then went on to claim that it goes with PWR too. At any rate, talking of breeder reactors is talking of hypothetical future reactors to be developed and made commercially viable, similar to fusion. It's not something that can be rolled out big-time now or before 2030, so the big push would first need Flamanville 3-style plants (as he mentioned) using mined uranium. (I just made another quick calculation: with an exponential increase of capacity from now until 2030 to reach the current world total electricity generation only, assuming the EPR's claimed fuel efficiency, the "reasonably assured reserves" of all grades claimed in OECD's Uranium2007 study would be gone in 2029, and the "inferred reserves" by 2035.)
