Apples to oranges. Reactor designs are completely different. They are basically set it and forget it designs that then require extremely costly refueling and refurbishment.
Edit: I was wrong, the Ultra Safe Nuclear plan is somewhat similar. My comparison was with typical power grid reactor designs, not disposable reactors like what's being proposed.
You're actually right, in this case it is pretty comparable, so it's closer to apples to apples, which brings up concerns about costs and commercial viability of such a project, but that's not really point of this thread.
