Source Terms for Advanced Reactor Spent Fuel Applications

In this training course, participants learn how to generate nuclide inventory for several 3D advanced reactor configurations, and how to analyze and post-process these data for use as input in other computational tools.

 Participants will learn how to: 

  • Use SCALE’s TRITON reactor physics sequence to generate core inventory data in the form of ORIGEN nuclide concentration files (f71)
  • Perform decay simulations for the determined inventory with ORIGEN
  • Interrogate the f71 files with the OBIWAN utility to ensure a thorough understanding of the available cases, the data at each position, and the applied normalizations. 

The TRITON portion of this training focuses on the TRITON 3D sequence with the KENO-VI and Shift Monte Carlo neutron transport codes. The data post-processing includes the generation of an easy-to-use inventory interface file (II.JSON) and relevant examples for further post-processing and analysis. This training course provides best practices for generating f71 files and teaches multiple approaches to interrogate and modify results.

 Previous experience with TRITON or ORIGEN is required.
