Indeed. Many microreactors of the past like the PM3A in Antarctica were just too expensive to operate and maintain so they got replaced with oil. SMRs are great for lower capital cost but they won't just automatically be cheap to operate. The nuclear industry has to focus heavily on getting maintenance and operation costs way down. Some of that is regulatory, but lots of it is inherent.
