An investigation of policy and technical aspects related to nuclear safety and security. Participants will evaluate the proliferation of risk from facilities within the nuclear fuel cycle. They will calculate the criticality conditions for a nuclear assembly and derive parent/daughter decay equations. Nuclear forensics evaluations will be conducted on real-world environmental measurements. Three lecture hours a week for one semester. Prerequisite: For engineering majors, Physics 303L and 103N or Physics 316 and 116L with a grade of at least C- in each; for others, upper-division standing and written consent of instructor.
