This is good news, relatively speaking.
SMR technology is one of the most promising pieces of technological development in the nuclear power space.
Standardized factory production and completely sealed, so refueling is only at the factory, never on-site. Their also, small, but scalable depending on the needs of each site.
I'm not sure of the design this company is using, but I'm assuming they're leveraging a fail safe reactor, as in, it requires properly running systems to generate fission, but if those systems fail, the fission process stops. There are no secondary systems that have to kick in, it's a simple as either it's running properly, or it can't run it all.
As opposed to systems like Chernobyl, or 3 Mile Island, that required separate active safety systems to guard against catastrophic failures. But if those failed, they're backups failed, etc., well, meltdown.
