This page collects together all documents related to Serpent validation. The different categories are listed below. Each entry should include one or several references to publicly accessible documents where the results are reported. If you have additional documentation related to an already listed case, you can just add the reference in the list.
Serpent input and output files can be also be provided. When the input consists of multiple files, link to zip or gzip archives.
Criticality
This section lists calculation cases from the International Handbook of Evaluated Criticality Safety Benchmark Experiments (ICSBEP)[1] and other sources. The main (but not only) purpose of the calculations is validation for criticality safety.

Research reactors & other experiments
This section collects studies involving full-scale modelling of research reactors and other experimental facilities. The results may include criticality calculations, but also other reactor physics data (flux or power distributions, spectral indices, etc.). Experiments focused on criticality safety validation alone should be included in the section above.
