Course Description

 

EM 463 is a follow-on course from EM362 which studies the principles of nuclear engineering.  The course uses the same text as EM362.  It is especially valuable for those strongly interested in a navy nuclear propulsion career.   The course consists of two lectures and one laboratory period per week.  The first lecture topic area studies advanced criticality analysis that integrates the principles of neutron slowing down theory into a multi-group spatial analysis.  A basic 3 group criticality diffusion code is provided to the students to understand these concepts.  The second lecture topic area studies the principles of power transient behavior in a nuclear reactor.  This topic is illustrated with applications to controls rods, fission product poisoning, fuel isotopic changes, and the load-following characteristics of a pressurized water reactor.  Special films are shown of both planned and unplanned nuclear criticality accidents and their consequences.  Simulation packages are used by the students that illustrate a pressurized water reactor’s transient response.    In this part of the course, the student learns the interactions between different systems that compose a nuclear power plant and the reactor core itself.  The final lecture topic area is the study of basic reactor shielding principles.  The laboratory portion of the course emphasizes experiments that measure basic nuclear parameters and illustrates the operating principles of nuclear instrumentation and data analysis.   Two field trips are normally conducted.  One trip is to the TRIGA reactor, which is located at the AFRRI facility in Bethesda, MD.  On this trip, several transient experiments are performed with the reactor initially in a critical state.  The second field trip is a visit to a local nuclear power plant such as Calvert Cliffs or Three Mile Island.  The laboratory experiments use the modern nuclear work stations as well as the  sub-critical reactor, neutron generators,  radiation sources, and detection equipment that are located in the laboratory.   Typically 11 laboratory experiments are performed over the course of the semester.   Normally one or two guest lecturers are brought in to speak on current and future issues facing the commercial nuclear industry or to lecture on special nuclear topics.  EM 463 like EM 362 emphasizes the light water reactor technology, which is employed by both the navy and commercial nuclear reactors.
