Of course, ramping up production brings an increased risk of manufacturing faults and construction errors in all cases.

Right now nobody has mastered the building of nuclear plants. As a civilization, we’re on the equivalent of our third day on the new job. If we committed to tripling world supply, that would lead to us mastering it. We’d be at the equivalent of having been at the job for a couple years.
