[QUOTE="BRNG ITT, post: 16164124, member: 33313"] Not sure I can watch this one. “Every atom of Uranium is a bullet...” Hollywood hogwash. When U-235 undergoes fission (by absorbing a low energy thermal neutron), it splits into 2 new atoms (called fission products) and releases large amounts of energy (binding energy) and, on average, 2.08 new thermal or fast neutrons that go on to possibly cause another fission event. (or could be absorbed by a poison or even escape the core and contribute to net loses.) It’s the the radiation energy such as alphas, betas, gammas and neutrons that act like “bullets” and do damage to organic cells. So the 92 electrons, 92 protons, and 143 neutrons (atoms) that make up Uranium 235 don’t all act like “bullets”. I’m willing to bet at some point in the show, someone will yell “The reactor is CRITICAL!!!!” (Critical is not a good or bad thing, it just means that net reactivity addition in the core is 0, as in you are not increasing or decreasing in power level, just stable. Who am I kidding, I’ll orobably watch it anyway though. [/QUOTE]
