In this video Prof. Ruzic explains what modular micro-reactors are, and why they may be the future of nuclear power. In particular, their ability to be a non-carbon source of process or district heat makes them an ideal replacement for fossil fuel plants. In terms of electricity cost, they compete very well with diesel generation, and once mass produced could reach utility-scale prices. The micro-reactors are self-contained with their own containment, and passive safety features provided by the laws of physics. All wastes generated are contained in the fuel itself which will last for 20 years. At that point the whole reactor vessel is carted away, and a new one can be installed.
