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

Verification

Analytical Verification

Suite A - Analytical multigroup fixed-source

Verification includes observing the $N^{-0.5}$ convergence in the errors (against analytical solutions) as the number of source particles $N$ is increased. The problems include:

• 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)

More involved problems that have no analytical solution are considered. MC/DC results are compared to those of OpenMC) (input scripts provided).

Multigroup

Verification includes observing the $N^{-0.5}$ convergence in the relative differences of the two codes as the number of source particles $N$ is increased. The problems include:

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

Continuous energy

Verification includes observing the agreement in the results of the two codes. The problems include:

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