What do the different sub-divisions in nuclear engineering do?
There are a couple of ways of looking at this. The broadest view of nuclear engineering does include the fusion vs. fission divide, and each of those can be broken out into controlled nuclear energy (reactors) and not-so-controlled nuclear energy (nuclear weapons). All of these involve nuclear engineering disciplines or the associated information found in many college courses. The “cross cutting” disciplines of radiological protection, training, operations, quality control, and maintenance are learned in school and also on the job at whatever nuclear facility you get to work at. All such considerations are high level. Experienced nuclear professionals also get to be plant inspectors, supporting the regulators or the nuclear facility operators. With those general thoughts in mind, it might be better to recast your question in terms of your personal goals. You first should realize that a true “nuclear engineer” is often someone with a doctorate in nuclear engineering. That true nuclear e
