Best Practices in Modeling and Simulation of Nuclear Materials for Nuclear Safeguards Practitioners and Early Career Professionals
ORNL, Oak Ridge TN
This 4-day, hands-on training course will provide instruction on best practices for modeling and simulations of nuclear materials to solve problems specific to nuclear safeguards using representative examples and exercises. Attendees of this course will acquire knowledge and skills that will significantly improve their capabilities to tackle safeguards problems they will face in practice. They will learn from instructors with extensive expertise in modeling and simulations on what are the best practices for using the computational tools for specific applications and on how to identify an incorrect usage of the software that can lead to potential poor decision making. The training will consist of three separate sections.
The first two days of the training will focus on ORIGEN, the depletion and decay code in the SCALE code system that has been internationally used for decades to predict spent nuclear fuel compositions and radiation emissions that are essential for a broad spectrum of spent fuel applications. Participants will learn how to generate ORIGEN libraries specific to different reactor fuels, how to use ORIGEN to estimate spent fuel inventories (e.g., U, Pu, fission products) in a reactor and generate neutron and gamma source terms in unirradiated and irradiated nuclear materials, and how to feed the inventories and source terms into nuclear detector models used in the safeguards field. The latest ORIGEN release in SCALE 6.2.3, which will be used for this training, features a modernized, user-friendly input, with enhanced autocomplete and results display capabilities under a new graphical interface.
On the third day of the training, participants will learn to use the Inverse Depletion Theory (INDEPTH) code, which uses ORIGEN as an engine, to reconstruct the initial enrichment, burnup, and cooling time of spent fuel rods or assemblies based on available destructive or nondestructive assay measurements. This type of analysis allows safeguards analysts to verify operator declarations using reconstructed values to ensure the peaceful uses of nuclear energy in a given country. After a brief introduction of the theory behind INDEPTH, participants will learn how to set up and run problems effectively using the INDEPTH graphical user interface and will work through several relevant examples to illustrate solutions to realistic safeguards problems.
The fourth day will highlight the features and purpose of the IAEA Design Information Questionnaire (DIQ) and how it should be used.
Cost: The course will be offered free of charge. At the end of the training, the attendees will receive an USB flash drive with copies of all presentations, input and output files for the tutorial and workshop problems. However, ORNL does not provide stipends or funding to cover travel-related expenses. While the course is open to participants from all nationalities, ORNL is not able to provide any assistance with visas.
Who can apply: The course is intended for nuclear safeguards practitioners and early carrier professionals who are interested in modeling and simulation of nuclear materials for safeguards applications. No prior experience with the computational tools used in the training is required. However, all attendees are required to have an individual license for SCALE 6.2.3-EXE, which is an export-controlled software, by the time of the training. SCALE 6.2.3 licenses can be requested from RSICC in the US, the OECD/NEA Data Bank in France, and the RIST/NUCIS in Japan. It is the responsibility of the attendees to request the license. Attendees who do not already have a license are recommended to apply for a license as soon as possible, to allow sufficient time for processing their request.
