    As far as I can tell from looking, there are no breeder reactors for large scale power generation, there never have been, and while multiple countries are trying, none of them have actually done it.

      There have been plenty. For example, the CANDU series of reactors developed in the 1950s and 60s. Breeder reactors were quite popular during the early days of nuclear power, as it was initially thought that there was maybe only 100 years’ worth of (easily accessible) nuclear material on earth, rather than the thousands (or tens of thousands) of years’ worth we know of now, due to both more reserves being discovered and also easier methods of fuel enrichment being developed. The fact that breeder reactors have fallen out of favour due to abundant fuel reserves certainly says something.

        I know there have been plenty of breeder reactors. What I can’t find is a breeder reactor in a scale large enough to generate power for a city. In fact, from what I read, that’s been tried more than once without success. Can you point me to a breeder reactor that was actually a useful test case for powering a city?

          The Wikipedia page for breeder reactors has a whole list you can even sort by output capacity. For example, the BN-800.

            What I’m reading on Wikipedia is that none of them have been used for large scale power generation yet. Which was what I was saying. Wikipedia showing what their output capacity is does not show how long that output capacity can be maintained or how much it might fluctuate.

            Otherwise, what do you think the reason is that no country has yet to use one to power any cities?
