AC 2007-3105: A PROJECT-BASED APPROACH TO TEACHING THE NUCLEARFUEL CYCLEErich Schneider, Dr. Schneider received his PhD in Theoretical and Applied Mechanics from Cornell University in 2002. During the final two years of his graduate study at Cornell, he held the position of Lecturer. From 2002-2006, he was a Technical Staff Member in the Nuclear Systems Design Group at Los Alamos National Laboratory. In January, 2006, Dr. Schneider joined the Mechanical Engineering faculty at the University of Texas at Austin. He is affiliated with the Nuclear and Radiation Engineering Graduate Program at that institution

. There is a strong interest among faculty to seek interested undergraduatestudent participation in their research projects. The undergraduate research has often been usedas a recruitment tool for graduate schools. The undergraduate research participation in generalhas benefitted both students and the faculty and has given rich experience to the graduatestudents and researchers who otherwise would not interact with undergraduate students. TheNuclear Engineering student groups are generally small and this interaction has more impact onstudent learning. The undergraduate research during summer and during academic year innuclear engineering program is reviewed. Key lessons learnt by faculty and graduate studentsand feedback by undergraduate students

Prior to or during new student orientation,students interact with the department’s freshman student adviser and student ambassadors. It isan opportunity for incoming students, and parents, to become familiar with the department, itsservices, facilities, research projects and career trends. In conjunction with the College ofEngineering orientation program, the department engages in its own orientation to satisfy theseobjectives. As important is the introduction of students to the professional society, the AmericanNuclear Society. Freshman students join the student chapter for

Students in the program areadditionally mentored by DOE personnel to complete interdisciplinary research projects relevantin nuclear application areas.Background and MotivationThe idea of automating the multitude of hazardous tasks associated with all phases of the nuclearfuel cycle (whether it be weaponized or energy producing) is not a new one. The positive impactof successful automation for safety and security is clear, yet the few successes have been costlyand time consuming. A review (as examples, Y-121, LANL2, INL3, ORNL4, SNL5, 6, andAcademia7) of the multitude of projects teaches an important lesson. Automation in the

The project addresses risk assessment, risk management, and reliability problems that arise in electric power generation. The research seeks to help industry officials make the best operational and executive management decisions by more accurately accounting for seemingly unpredictable issues such as outage duration and regulatory safety constraints, as well as uncertainty related to energy prices, mechanism failures, repair costs and other factors.Kendra Foltz-Biegalski

Prompt gamma activation analysis is a technique used to detect the presence in µg to gamounts of many elements in a sample irradiated with a beam of neutrons. When the atoms inthe sample absorb some of the neutrons, they emit prompt (immediate as opposed to delayedproduction of gamma rays) gamma rays. A gamma-ray spectrometer measures the energies inMeV of these rays and identifies the constituent elements of the sample. The peak intensities ofthe peaks are in correspondence to elemental concentrations. The amount of analyte element isgiven by the ratio of

is extremelyimportant that students understand the value of nuclear engineering prior to that moment.Equally important to the point of engagement is the message. In 2006 the WGBH EducationalFoundation for the Extraordinary Women Engineers Project found that in thinking about futurecareers, young girls want to make a difference, work with people, have job flexibility and earngood money – results echoed in the Department of Energy’s National Marketing Project ofuniversity aged students. The desire does not change, as they get older; as such, nuclearengineering must accentuate this message in age appropriate ways. Page 12.559.3

These reforms will allow the NRC licensing process to continue to provide effectiveregulation of construction and operation of plants; and will preclude the uncertainties utilitiesfaced on construction projects in the 1970s and ‘80s. Congress has also enacted legislation thatcalls for NRC issuance of a single license prior to construction to provide for both constructionand operation of plants
