There is a 5-10 year lead time between digging the first hole and opening the plant. That's >$100 million in capital investment for 5-10 years without any return, so the plant has to have a present lifetime value >$140 million the day it opens.
This ignores various risk cases associated with building a plant that drive the return on capital further up.

I am unaware of any kind of practical nuclear fission machine that doesn't require a high initial capital investment. Could you link some examples of commercially operating units? It has been a few years since I was in the field but I was unaware of any proven changes to the fundamental economics of the industry.
There's a good chance you can see one at your local university or shipyard. The post to which you're replying doesn't use the terms "proven" or "commercial", so let's not move the goalpost. Then we can talk about YC-funded startup UPower, Fluor-owned corporation NuPower, etc. Studying engineering is also a good way to reduce reliance on examples.
I was unable to find any data on the 'NuPower' technology; could you provide links?
What I found on UPower indicated that it's a nuclear thermal battery, I love that technology but they aren't legal and wont be because of widespread concerns about terrorism and radioactive contamination.
Also, my educational background is in engineering and I have worked on determining whether it's financially feasible to build power plants for a living. I would really love it if you could provide some evidence for your arguments.
NuScale Power, sorry (mobile typo). UPower are making a reactor but some sources have incorrectly called it a battery. There are no laws in the U.S. (or any nation I'm aware of) that make small reactors or nuclear batteries illegal. My only argument so far is "Nothing about nuclear fission requires startup capital to be large", which is trivially true.
