The ICSBEP Handbook is available on DVD and Online. To obtain the access to either the DVD or the Online version, you must submit your request using the following link: https://www.oecd-nea.org/jcms/pl_20291/international-criticality-safety-benchmark-evaluation-project-icsbep-handbook
The Criticality Safety Benchmark Evaluation Project (CSBEP) was initiated in 1992 by the United States Department of Energy. The project quickly became an international effort as scientists from other interested countries became involved. The International Criticality Safety Benchmark Evaluation Project (ICSBEP) became an official activity of the Nuclear Energy Agency (NEA) in 1995.
This handbook contains criticality safety benchmark specifications that have been derived from experiments performed at critical facilities around the world. The benchmark specifications are intended for use by criticality safety engineers to validate calculation techniques used to establish minimum subcritical margins for operations with fissile material and to determine criticality alarm requirements and placement. Many of the specifications are also useful for nuclear data testing. Example calculations are presented; however, these do not constitute a validation of the codes or cross-section data.
The evaluated criticality safety benchmark data in the 2020 edition are presented in nine volumes. These volumes span over 80 000 pages and contain 587 evaluations with benchmark specifications for 5121 critical, near-critical or subcritical configurations, 45 criticality alarm placement/shielding configurations with multiple dose points for each, and 237 configurations which have been categorised as fundamental physics measurements that are relevant to criticality safety applications.
New to the handbook are experiments from the Kilopower Reactor Using Stirling Technology (KRUSTY) – shown on the front cover - and Thermal/Epithermal eXperiments (TEX) programs performed at the National Critical Experiments Reserach Center (NCERC) in the United States; Highly Enriched Uraniums experiments with Lucite at NCERC; pitch variation experiments at Sandia National Laboratory in the United States; and structural material experiments at Valduc facility in France.
Experiments that are found unacceptable for use as criticality safety benchmark experiments are discussed in these evaluations; however, benchmark specifications are not derived for such experiments (in some cases, models are provided in an appendix). Approximately 838 experimental configurations are categorised as unacceptable for use as criticality safety benchmark experiments. Additional evaluations are in progress and will be added to this document periodically. The document is organised in a manner that allows easy inclusion of additional evaluations as they become available.

This handbook was prepared by a technical review group that benefited from the input of experienced criticality safety personnel from various countries, which have included over the years Argentina, Brazil, Canada, China, Czech Republic, France, Hungary, India, Israel, Italy, Japan, Kazakhstan, Korea, Poland, the Russian Federation, Serbia, Slovenia, Spain, Sweden, the United Kingdom and the United States. The handbook includes the project organisation and a list of participants by order in which countries joined the ICSBEP.
