MODERATORS
I am hopeful for small modular reactors (SMR's). They have the potential for significant construction cost savings, are less of a risk from terrorism/disaster, and can often be located closer to the load (long power lines lose power).
There have been a number of studies that have SMRs are being as expensive or higher than conventional nuclear, with the added downside of higher levels of waste, anywhere from 2 to 30 times as much as conventional nuclear depending on the tech used.

Part of the reason for scaling up reactors in the first place was the expectation that output would scale faster than costs. That hasn't really panned out to the extent expected.
Thanks for sharing this, I didn't know how the waste compared to conventional nuclear.
