I have never seen these figures for nuclear (or more appropriate to the
current area of application, small diesel).  If this exercise was intended
to be a economic comparison between technologies, why not keep the
rules consistent.

As has been pointed out, lifetimes for cells other than amorphous Si
are longer than just about any technology with moving parts that you
would like to name.

BTW, just who is it that ever said that any energy technology was eternal?
