If they really work in this factory like shown in that video, handling radioactive material in the production process with little personal protection (especially against airborne dust), then at least I for one would not like to work for them, ever. The safety of "final" product notwithstanding (that's fine), the shaping, size sorting and sintering processes create dust and really, you don't want to get that into yourself.
1. Build prototype
2. Iterate on prototype.
3. In conjunction start standardizing and automating processes.
4. Achieve large enough scale to amortize the factory and process optimization costs over enough units to actually gain anything.
The “SMR hype industry” seems to be perpetually stuck at 1, not even being able to deliver a single prototype.
All the while talking like the factory already exists and SMRs are solved.
Somehow it doesn’t add up.
