> And yes the CSIRO report is Australia-specific but the timeframes for building nuclear power in the US are similar

* The US has existing commercial scale nuclear power stations. Australia does not.

* The US has an existing nuclear weapons industry. Australia does not.

* The US has existing advanced courses on nuclear technology for workforce scale populations. Australia has extremely limited coursework.

* The US actively builds and maintains SMRs for submarine use. Australia does not.

These are fairly critical differences in terms of additional costs to Australia above and beyond build times.
