Atomic Frontiers: From Fission to Fusion

This course examines the science and engineering of nuclear energy, starting with the fundamental physics of fission and the strong nuclear force. It covers the mass defect and the neutron life cycle, explaining how the state of criticality is maintained to generate steady power. You will study the technical design of Pressurized Water Reactors and Boiling Water Reactors, focusing on the function of moderators, coolants, and thermal-hydraulic loops used to convert atomic heat into electricity. The curriculum also provides a rigorous analysis of historical accidents, including Chernobyl and Fukushima. These case studies illustrate the evolution from active cooling systems to modern passive safety designs and the environmental impact of radioactive isotopes like Iodine-131. The program transitions to the frontier of nuclear fusion and the challenges of overcoming the Coulomb Barrier. It details the methods for achieving plasma confinement through Tokamaks and laser-based inertial systems, aiming for net energy gain. The discussion then moves into the modern nuclear economy, focusing on Small Modular Reactors and the rise of private fusion ventures. These innovations represent a shift from massive state-funded projects to flexible, factory-built designs that lower capital costs. Finally, the course explores long-term sustainability through breeder reactors and the development of a closed fuel cycle. This series offers a technical overview of how nuclear technology continues to evolve toward providing abundant, carbon-free energy for human civilization.
