Doctoral Degree

Nuclear Engineering PhD

Students in the field of nuclear engineering desiring to study for the Doctor of Philosophy degree must have a Bachelor of Science or Master of Science from a recognized university with a major in engineering, physics, chemistry, or mathematics. All candidates will be required to demonstrate general competence in a comprehensive examination in the areas of nuclear reactor engineering, radiological engineering, and a chosen specialty area.

Radiation Instrumentation Interdisciplinary Graduate Education

The Radiation instrumentation Interdisciplinary Graduate Education (RIDGE) program began in the 2015-2016 academic year in order to establish a closer connection between engineering departments that contribute to radiation instrumentation systems research and development. The program is geared toward education of PhD-seeking students through coursework and research. Through this program a student may earn either a MS degree in nuclear engineering, computer engineering, or materials science engineering along the way to the nuclear engineering PhD, while also receiving a certificate in Nuclear Security Science and Analysis. A sample curriculum along with other suggested milestones for a student seeking a PhD in nuclear engineering can be found on the RIDGE website. For more information about this program please contact Jason Hayward.
