Small modular nuclear reactors get a reality check in new report (newatlas.com)

[T]he report's executive summary certainly gets to the heart of their findings.

"The rhetoric from small modular reactor (SMR) advocates is loud and persistent: This time will be different because the cost overruns and schedule delays that have plagued large reactor construction projects will not be repeated with the new designs," says the report. "But the few SMRs that have been built (or have been started) paint a different picture – one that looks startlingly similar to the past. Significant construction delays are still the norm and costs have continued to climb."

I specifically picked the statistic that claimed to have included the full cost of installing something new. Most other statistics only include prolonging the life of existing plants, thus ignoring the installation costs completely. You can just quote the paragraphs that prove your point the same way I have and then we can discuss further. Maybe I made a mistake, who knows.

Or you could... Actually read the entire source you linked? It's a pretty good article and goes into a lot of detail on why LCOE estimates vary significantly between countries and depending on discount rate assumptions, so quoting one specific number is useful context but not the full story.

The problem isn't whether the LCOE numbers you quote consider the capital costs - they do, and that's correct - so do the ones in the table below it. It's that those are average values taken from the USA, which has among the highest capital costs for installing new reactors in the world. At best that tells us that fusion isn't cost competitive in the USA right now.
