That is never going to happen until we are building more of a consistent design. I think every LWR is use today is a custom bespoke piece of equipment.
Yes, standardizing on a handful of designs will help immensely, as well as building two or more reactors on one site to share the overhead costs between units.
For example, building out more AP-1000s is really a no brainer. The first-of-a-kind is always expensive and the AP-1000 was especially so due to many factors. We bore that cost and now we should reap the benefits of Nth of a kind builds.
