The document discusses fundamentals of mechatronics and nuclear fission reactor technology. It describes how a nuclear reactor works by sustaining a controlled nuclear chain reaction, unlike a nuclear bomb. It then covers various stages of the nuclear fuel cycle from mining and processing uranium to use in reactors, interim storage, and reprocessing. Finally, it discusses different types of nuclear reactors including generations I-IV and examples like molten salt reactors, sodium-cooled fast reactors, and lead-cooled fast reactors.

11. Reactor A nuclear reactor is a device in which nuclear chain reactions are initiated, controlled, and sustained at a steady rate, as opposed to a nuclear bomb , in which the chain reaction occurs in a fraction of a second and is uncontrolled causing an explosion.
