This course is an advanced version of the Nuclear Engineering Core Sequence course NE 350. This course focuses on nuclear reactor systems, the release of nuclear energy in the reactor core, and its removal as heat for producing electric power. Specific topics emphasize reactor kinetics, heterogeneous reactors, control rods and shim, reactor poisons, heat transfer, and control and design of the reactor core. The fundamentals of transport theory and the solution to the transport equation using Monte Carlo N-Particle (MCNP) transport code are introduced. Design projects apply the concepts presented to practical problems.
