• University of Nevada, Reno Graduate Certificate in Nuclear Packaging:  In 2016, the University of Nevada, Reno (UNR) Mechanical Engineering (ME) Department began offering a 9-credit Graduate Certificate in Nuclear Packaging (GCNP).  It developed this certificate in coordination with the U.S. Department of Energy's Packaging Certification Program (DOE PCP).  The Certificate and its courses have been approved by the Northwest Commission on Colleges and Universities (NWCCU), Redmond, WA.
  
  The GCNP provides a curriculum in packaging for nuclear and other radioactive materials that complements graduate programs in Mechanical Engineering, Nuclear Engineering, and Materials Engineering and is more applied-knowledge-based than research based.  The admission requirements is an earned baccalaureate degree in mechanical, materials, nuclear or a closely-related engineering field, or a baccalaureate degree and background in project management related to packaging of nuclear and other radioactive materials.
  
  The goals of the certificate program are to (a) to encourage students to complete a curriculum in packaging safety and security of nuclear and other radioactive materials that has both depth and breadth, and (b) provide a graduate-level curriculum designed to give students an advantage when seeking employment or advancement in the area of packaging of nuclear and other radioactive materials, or related fields.
  
  The following nine courses were developed and are offered on a regular basis for DOE PCP by the Argonne (ANL), Lawrence Livermore (LLNL), Oak Ridge (ORNL), Sandia (SNL), and Savannah River (SRNL) National Laboratories, etc.; and the courses are assigned the following UNR NP (Nuclear Packaging) course numbers (the former ME course numbers are also shown):
  
  1. NP 600 (formerly ME 691) American Society of Mechanical Engineers (ASME) Pressure Vessel Code for Nuclear Transport and Storage, 1 credit (offered at ANL or UNR)
  2. NP 601 (formerly ME 692) Quality Assurance (QA) for Radioactive Material Packaging and Storage Casks, 1 credit (offered at ANL or UNR)
  3. NP 602 (formerly ME 695) SARP Review and Confirmatory Analysis, 2 credits (offered at LLNL)
  4. NP 603 (formerly ME 696) Management of Safety Analysis Report for Packaging (SARP) Preparation, 1 credit (offered at SRNL)
  5. NP 605 (formerly ME 698) Thermal Modeling and Testing of RAM Packages, 1 credit (offered at SNL)
  6. NP 607 (formerly ME 690) Radiation and Nuclear Criticality Analysis of RAM, 1 credit (offered only at ORNL)
  7. NP 608 (formerly ME 697) Radioactive Material Package Operations and Leak Testing, 1 credit (offered at SRNL)
  8. NP 610 (formerly ME 694D) Nuclear and Other Radioactive Materials Transport Security, 1 credit (offered at ANL)
  9. NP 611 (formerly ME 694I) Nuclear and Other Radioactive Materials Transport Security, 1 credit (offered at ANL)
  
  In addition the following six 3-credit courses, offered by the ME and Materials Science and Engineering (MSE) programs at UNR, are part of the curriculum.
  10. ME 695 Introduction to Combustion  
  11. MSE 601 Corrosion of Metals
  12. MSE 665 Nuclear Power Fundamentals
  13. MSE 666 Nuclear Fuel Cycle
  14. MSE 667 Radiation Detection and Measurement 
  15. MSE 668 Nuclear Materials.
  
  Finally, student may take the following internship course at national laboratory, nuclear industry or government sites
  16. NP 640 (formerly ME 699 ) Nuclear Packaging Internships, 3 credits
  
  UNR is currently working with national laboratory content experts to develop and gain University approval for the following two new 1-credit national laboratory elective courses.
  17. NP 620, Fundamentals of Nuclear Security, 1 credit, being developed by Sandia National Laboratories
  18. NP 630, Fundamentals of Nuclear Safeguards, 1 credit, being developed by Oak Ridge National Laboratory
  
  Students who enroll in these DOE PCP classes will receive UNR graduate credit if they: (1) Gain special graduate admission to UNR, (2) Enroll in the UNR course and pay tuition, and (3) Pass the course. These credits may be applied toward graduate degrees at UNR or any other university that accepts that credit.
  
  If students receive a C grade or better in a class, then the student will be able to use the credits toward UNR’s 9-credit GCNP. To earn the Certificate, students must complete NP 600, NP 601 and NP 602, which are required.  They must take 5 additional elective credits from the above list.  Finally, to earn the GCNP, students must earn least a B average in the courses.

• University of Nevada, Reno Graduate Certificate in Transportation Security and Safeguards: UNR is currently working with national laboratory content experts to establish a new 9-credit Graduate Certificate in Transportation Security and Safeguards (GCTSS).  Security and safeguards of nuclear and radioactive materials must be maintained at all times during their life cycle, especially during transportation.  Packaging is central to this effort.  The new certificate will take advantage of courses that UNR and the national labs have established for the GCNP.  The new GCTSS will require the following four courses, which present essential information and skills, NP 620 (Fundamentals of Nuclear Security), ME 630 (Fundamentals of Nuclear Safeguards), NP 600 (American Society of Mechanical Engineers (ASME) Pressure Vessel Code for Nuclear Transport and Storage), and either ME 610 (Nuclear and Other Radioactive Materials Transport Security-Domestic) or ME 611 (Nuclear and Other Radioactive Materials Transport Security-International).  The GCTSS curriculum will also require 5 credits of electives, from a family of courses and the nuclear packaging internship.

• FY 2020 Course Schedule: Listed below are the Packaging Certification Program (PCP) courses planned in FY 2020.  Courses with NP 6xx prefixes are available for graduate credit at University of Nevada, Reno.  Registration information and course fees will be emailed to RAMPAC subscribers (click here and follow the instructions to be added to the RAMPAC email list) and posted on this page when the registration websites are activated.  Note to DOE/DOE Contractors:  DOE PCP courses are an exempted event and therefore are not subject to the conference management approval and reporting process.
