Things to check in case of suspicious results

Unresolved resonance probability table sampling

Unresolved resonance probability table sampling is not used in Serpent by default. This method is needed to account for self-shielding effects in the unresolved resonance region. The effect is usually not significant in thermal systems, but can lead to noticeable discrepancies in fast-spectrum systems.

Probability table sampling is switched on using the Input syntax manual#set ures set ures option.
