This is true for water cooled reactors, which these are, thanks to a regulatory environment going back to the Nixon administration that mostly makes other designs unavailable, as the cost of safety measures is quite high, but comes down with scale on a per-watt basis. The exciting thing about small modular reactors is with alternative designs, such as molten salt designs and alternative fuels such as thorium, where the risk of meltdown and hydrogen explosion are not an issue, so this cost-of-safety factor falls away heavily. Molten salt DOES bring with it issues of corrosion, so it's not a panacea, but the idea is that some of these alternative designs can bring the power generation closer to where the power is used, which raises a variety of benefits, including being able to potentially use the heat generated in a useful manner in addition to the electricity, rather than solely as something to be safely dissipated. Also, of course, you get rid of the big single points of failure and end up with a more resilient power grid. I can't speak to this particular company's offering but I am glad to at least see some interest in the technology growing, as nuclear at this point is the only realistic way to both even consider replacing existing fossil fuel use as well as powering the increased energy demands of the future particularly in light of rapidly developing emerging markets and much heavier power draw from technologies such as generative large language models (so called "AI").
