A collection of verification, validation, and performance test suites for MC/DC.

Verification

Analytical Verification

Analytical verification involves observing the $N^{-0.5}$ convergence in the errors (against analytical solutions) as the number of source particles $N$ is increased.

Neutron transport

Suite A - Analytical multigroup fixed-source

• Steady-state flux distribution of a purely-absorbing multi-layer slab system
• Reed's classic 1D problem [reference]
• Flux temporal propagation from an isotropic planar surface source
• Variations of the AZURV1 transient benchmark [reference]
• Spectrum temporal evolutions from pulsed homogeneous infinite SHEM361-group thermal systems

Benchmark verification (Code-to-code comparison)

Benchmark verification considers more involved problems that have no analytical solution. Verification is guided through agreement in code-to-code comparison.

Neutron transport

MC/DC results are compared to those of OpenMC). Two physics modes are considered:

• Multigroup: Verification involves observing the $N^{-0.5}$ convergence in the relative differences of the two codes as the number of source particles $N$ is increased.
• Continuous energy: Verification involves observing the agreement in the results of the two codes.

Multigroup

• Time-dependent version of the Kobayashi Dog-Leg transport benchmark [Zenodo link]
• Four-phase C5G7 transient benchmark [Zenodo link]

Continuous energy

• Temporal spectrum evolutions of neutron-pulsed pincells with various materials:
  • UO2 and Water
  • UO2 and Helium
