Explore the science and engineering associated with the design, evaluation, and implementation of systems to secure nuclear and radiological materials. Examine methods for planning and evaluating nuclear security activities at the state and facility level. Study the characterization of the adversary, categorization of targets and the consequences associated with failure to protect those targets, detection and delay technologies, on-site and off-site response as well as different response strategies, evaluation of insider threats, mathematical methods for evaluating risk due to the threat and the security system design, and methods for risk minimization and system optimization will also be studied. Mechanical Engineering 390E and 397 (Topic: Nuclear Security Sys Design) may not both be counted. Three lecture hours a week for one semester.
