Why Engineers Are Shrinking Nuclear Reactors

What if the future of nuclear power isn't a giant reactor... but hundreds of smaller ones? Engineers around the world are developing Small Modular Reactors (SMRs) — compact nuclear reactors designed to be manufactured in modules, transported, assembled and potentially deployed wherever reliable electricity is needed. In this documentary, we explore how SMRs work, why engineers are trying to make nuclear reactors smaller, how nuclear fission produces electricity, how passive safety systems can work, and why factory-based manufacturing could change the economics of nuclear power. We also look at the biggest challenges standing in the way: construction costs, nuclear fuel, regulation, radioactive waste and the difficulty of producing reactors at large scale. And with electricity demand growing from AI data centers, industry and electrification, the question is becoming increasingly important: Could small modular reactors become a major part of the world's future power system? Watch until the end to understand why making a nuclear reactor smaller may actually be one of the biggest engineering challenges in modern energy.
