Nuclear Engineering is a field that deals with the application and development of nuclear energy for practical purposes. It involves researching, designing, building, and operating systems that utilize nuclear reactions to generate heat or electricity. This can include things like nuclear power plants, radiation therapy machines used in cancer treatment, and even nuclear weapons. Nuclear engineers work with radioactive materials and must have a deep understanding of the principles behind nuclear physics and engineering concepts such as thermodynamics, fluid mechanics, and heat transfer to design safe and efficient systems that can harness the power of nuclear energy while minimizing potential risks.
