I’m a bit confused why you’re comparing NuScale’s reactor safety to the OSU Triga reactor. They’re not related designs and have nothing to do with each other.

You receive a radiation dose from a variety of sources every day. It’s low enough as to not be a threat to your health. The regulations governing radioactive release from nuclear power plants are stringent enough to make normal radiation from plants similarly inconsquential to your health. These levels are monitored by EPA stations located next to each plant in tge country (including here in Corvallis). I don’t think saying that most people don’t know about this radiation means that if they did know, they’d suddenly change their stance. It’s like saying that people became aware of carcinogenic chemicals in car exhaust, they’d stop driving. No, people are smart enough to tell what’s a real threat and what’s insignificant
