Lecture 1: Introduction to 22.04 and the History of Nuclear Power
MIT OpenCourseWare · 1:13:09 · Yesterday
The dominance of pressurized water reactor (PWR) technology in the United States resulted from Cold War military necessity rather than a market-driven evaluation of the most efficient or safe design. This technological trajectory was established when the U.S. Navy prioritized compact, high-performance reactor systems for submarine deployment, which were later institutionalized as the industry standard through government-backed international trade and subsidies.
- Stellar energy origins — Early theories on why stars shine were incorrect, but further study into atomic processes eventually revealed nuclear fusion as the underlying mechanism .
- Chain reaction discovery — Leo Szilard identified that splitting atoms could yield massive energy, which triggered immediate government secrecy and military oversight .
- Wartime secrecy — Development of atomic technology during World War II created a centralized bureaucratic model, where information was strictly controlled and government funding became essential .
- Military engineering priority — The U.S. Navy required reactors small enough to fit inside submarines, leading to the selection of pressurized water designs because engineers were already familiar with water-based corrosion and heat transfer .
- Budgetary constraints — Post-war cuts to Atomic Energy Commission funding forced researchers to abandon various experimental reactor designs, forcing them to rely on the Navy's already-developed water systems .
- Market intervention — The U.S. government used foreign aid, specifically through the Euratom program, to guarantee international customers for domestic companies, effectively forcing the pressurized water reactor into the global market before other concepts could compete .
What role did foreign aid play in establishing the market position of early U.S. nuclear technology?
