USN reactor designs are quite different from civilian reactor
designs for a number of reasons. In Particular, the former
use more highly enriched-fuel to minimize their size. That
is unnecessary for a baseline US utility, and also undesirable
from a proliferation perspective.

The thought process is that if we used smaller reactors and stop designing
the damn things everytime one get's built they would be more affordable. I
have no problem with guarding the hell out of them. It would be cheaper than
the way we have done it in the pass.

Using a common design for all nuclear power reactors in
the US would require the elimination of competition between
the companies building them. So long as we have quasi-public
utilities, that won't happen. France has a Socialist economy.

As for proliferation issues, US designs are sold overseas,
to countries like South Korea. Egypt and at one time Iran.
The light water moderated low-enriched Uranium design that
is inherently proliferation-resistant is advantageous and not
really much of an impediment from an engineering standpoint,
to economy. Major design differences for the export market
would be a problem.
