Deterministic Time-Dependent Neutron Transport Benchmark without Spatial Homogenization (C5G7-TD)

The ARDOR Lab has been actively participating in the coordination of the Organization for Economic Co-operation and Development Nuclear Energy Agency (OECD/NEA) Deterministic Time-Dependent Neutron Transport Benchmark without Spatial Homogenization (C5G7-TD).

The main objective of this benchmark is to specify a series of space-time neutron kinetics test problems with heterogeneous domain description for solving the time-dependent group neutron transport equation without feedback. Physical materials in these benchmarks are described by transport macroscopic cross-sections. Such benchmarks would allow carrying out verification of developed deterministic codes and rigorously revealing methodical errors. Moreover, such benchmarks would allow studying possible inaccuracy of spatial homogenization and diffusion approximation in time-dependent cases. After the completion of the proposed kinetics benchmark, it will be extended to more realistic dynamics benchmark, which will take into account the thermal-hydraulic feedback mechanisms. More information about C5G7-TD can be found on the benchmark website.
