SCALE/TRITON Lattice Physics and Depletion

The TRITON reactor physics sequence in SCALE simulates the time-dependent transmutation of various materials in 1D, 2D, or 3D depletion models by coupling neutron transport solvers with the depletion and decay code ORIGEN. TRITON coordinates all steps involved, including nuclear data processing, neutron transports for 1D, 2D, and 3D configurations, and transmutation and decay to estimate nuclide compositions of depleted mixtures, mixture-wise powers, neutron flux, and other important quantities as a function of burnup.  

Attendees of this course will learn how to use TRITON, with focus on 2D depletion analysis that uses the NEWT deterministic kernel for neutron transport. Besides the material and geometry model development, capabilities like branching and time-dependent perturbations of densities and temperatures will be covered in detail.  

Advanced capabilities such as ORIGEN library generation for rapid spent fuel characterization calculations, the application of KENO for 3D depletion, and using SCALE’s Sampler sequence to perform uncertainty analysis for model parameters and nuclear data in the TRITON input will also be demonstrated in this training. 

No prior knowledge of SCALE is required.
