Hi everyone,

I would be interested to know if anybody is using the B1 iteration mode in SERPENT?

I am working on the derivation of an actual B1 model for Monte Carlo calculations (yet based

on a multigroup form) and it would be great to have some idea of whether the SERPENT model is effective, and what kind

of Monte Carlo lattice calculations would typically require a regular leakage model.

For the time being, comparisons between SERPENT (B1 iteration mode) and deterministic B1 calculations

with the DRAGON code give me some differences, but it is likely to be due to differences in the models themselves.

So let me know if you have non-restricted references on this topic, or comparison between SERPENT and other lattice codes such as CASMO, HELIOS or whatever, or simply your opinion on the relevance of Monte Carlo leakage models for criticality calculations!
