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.
