Every Nuclear Reactor Type Explained: PWR, BWR, CANDU, SMR & Fusion

If you want to go deeper than this video and actually understand nuclear science, reactors, radiation, and nuclear technology, these are some of the best academic resources we recommend: Fundamentals of Nuclear Engineering: https://amzn.to/3Susgyw Radiation Detection and Measurement: https://amzn.to/4oonaQA 8 nuclear reactor types — from the world's most common PWR to experimental sodium-cooled fast reactors — fully explained in one video. Nuclear power generates roughly 10% of the world's electricity, yet most people can't explain the difference between a pressurized water reactor and a boiling water reactor — let alone why the Soviet RBMK was fundamentally unstable. In this video, FeynBox breaks down every major nuclear reactor design currently in operation or active development: PWR, BWR, PHWR/CANDU, Magnox, AGR, RBMK, HTGR, Pebble Bed, and Sodium-Cooled Fast Reactors. For each design, we cover how the reactor works, what makes it distinct, why engineers chose that configuration, and where it's used today. You'll understand the role of moderators, coolants, and fuel types — and why small engineering decisions in reactor design have enormous consequences for safety, efficiency, and the future of nuclear energy. Built for engineers, science enthusiasts, and anyone serious about understanding how nuclear power actually works. #NuclearEnergy #NuclearReactor #Engineering Chapters 0:00 Pressurized Water Reactor (PWR) 0:32 Boiling Water Reactor (BWR) 1:07 Pressurized Heavy Water Reactor (PHWR/CANDU) 1:44 Gas-Cooled Reactor (Magnox and AGR) 2:25 Light Water Graphite Reactor (RBMK) 2:59 High-Temperature Gas-Cooled Reactor (HTGR) 3:36 Pebble Bed Reactor 4:15 Sodium-Cooled Fast Reactor (SFR) 4:50 Lead-Cooled Fast Reactor (LFR) 5:24 Gas-Cooled Fast Reactor (GFR) 6:04 Molten Salt Reactor (MSR) 6:38 Fluoride-Salt-Cooled High-Temperature Reactor (FHR) 7:15 Supercritical Water Reactor (SCWR) 7:53 Small Modular Reactor (SMR) 8:29 Microreactor 9:06 Research Reactor 9:46 Naval Reactor 10:23 Breeder Reactor
