Degree Requirements (60 Post-Baccalaureate Hours)
For doctoral degrees in nuclear engineering: A Ph.D. student must complete 12 hours of dissertation credit leading to a dissertation. A student with a master’s degree in mechanical engineering or a closely related field must take at least 18 hours of graded graduate courses. A student without a master’s degree must take at least 48 hours of graduate courses, of which 42 or more hours must be graded graduate courses. The remaining hours can be in research (EMCH 797), and the graded graduate courses must include the core courses required of all master’s degree students.
