Nuclear engineering includes a lot of different sub-areas of study.
Neutron transport and shielding work also involves a lot of math. Nuclear criticality or nuclear safety work also uses a variety of mathematical applications. I cannot speak for anyone but myself in what I like about the field of nuclear engineering. I do not currently work in the power engineering end of the profession as I did earlier in my career, but I found it exciting to deal with power reactors and how they use nuclear energy to act basically as a heat source that produces steam to generate electricity. More recently in my career I have been involved with nuclear waste disposal and the nuclear engineering principles I studied long ago come into play in dealing with the long term disposal issues that have to be dealt with at waste repositories.
