Nuclear Reactor Physics
First Part:
Prepare slides keeping in mind half of the committee is out of your field.
Practice with students from and out of reactor physics.
Don't try to present everything. Present what the committee must understand and present what would lead to questions you like.
Communication lab is helpful.
Second Part:
