It’s odd to say never when you can see on the chart there was a twenty five year break in any new capacity.

Their new reactor designs have been going over budget and having startup problems like many other modern nuclear builds.

Just outright cancelling their breeder program sure sounds like wavering to me. What that action implies is that France doesn't consider it likely that nuclear will grow enough soon to require breeder reactors to be built, which means they think that nuclear is not going to be what solves the CO2 problem (which would globally require so many reactors that burner reactors alone would exhaust economically available uranium in less than a decade.)
