Understanding Nuclear Power
summary
Covers actual reactor designs and failure modes: pressurized water reactor makes up ~70% of plants with water as moderator and a primary/secondary loop; fuel is ~4% U‑235 (natural ~0.7%), 63 kg U‑235 powers Hiroshima, plutonium bombs use ~6 kg plutonium. Explains Three Mile Island valve and human-error sequence, Chernobyl’s RBMK core ejection of ~50 tons, Fukushima’s diesel-generator flood, and argues for factory-built small modular reactors and on-site fuel swapping to cut costs.
