The evaluated criticality safety benchmark data contain 570 evaluations with benchmark specifications for 4 913 critical, near-critical or subcritical configurations, 45 criticality alarm placement/shielding configurations with multiple dose points for each, and 215 configurations that have been categorised as fundamental physics measurements that are relevant to criticality safety applications. New to the 2016 International Criticality Safety Benchmark Evaluation Project handbook are 15 critical experiments with highly enriched uranium in an iron matrix performed to support the design of a repetitively pulsed reactor called the Sorgenta Rapida Reactor (SORA) at the Eurotom Research Centre in Ispra, Italy.
