Nuclear engineering designs and studies systems that use nuclear reactions or manage materials with radioactivity. Its subjects include nuclear reactors, radiation detection, radiation shielding, nuclear fuel, the behaviour of structural materials under irradiation, and radioactive waste management.
A nuclear power plant shows why several areas of engineering must work together. Nuclear fission releases energy; a coolant transports the resulting heat; a heat engine converts part of that heat to mechanical work; an electrical generator produces electrical energy. In a pressurized water reactor, a heat exchanger transfers heat from the pressurized reactor coolant to a separate circuit that produces steam. Thus neutron physics, heat transfer, fluid mechanics and materials science constrain the same design.[ref]
Nuclear engineering is a branch of engineering that deals with the processes, systems, and instruments used to harness and utilize nuclear energy and radiation. It encompasses a wide range of applications, including the design, construction, operation, and maintenance of nuclear power plants, the development of nuclear reactors, and the handling of radioactive materials. Key areas of focus in nuclear engineering include: 1. **Nuclear Reactor Design**: Engineering reactors to generate electricity efficiently and safely.
