Modern reactor designs (Gen III+, and proposed Gen IV) have passive safety systems — meaning they rely on gravity and convection, not active cooling pumps, to shut down safely. The plant fails safe even if power is cut. The public perception of nuclear risk is shaped almost entirely by Chernobyl and Fukushima, both of which involved older reactor designs under extraordinary circumstances. The actual deaths-per-terawatt-hour comparison puts nuclear below coal, gas, and even solar when you include manufacturing accidents. I'm not saying nuclear is without risk — waste storage is a real unsolved problem. But the risk model most people carry doesn't reflect what modern plants actually look like. How much does design generation matter when you're thinking about nuclear expansion?
