International Criticality Safety Benchmark Evaluation Project (ICSBEP)

The International Criticality Safety Benchmark Evaluation Project (ICSBEP) Handbook contains criticality safety benchmark specifications that have been derived from experiments that were performed at various critical facilities around the world. The benchmark specifications are intended for use by criticality and safety analysts as well as nuclear data evaluators to validate calculational techniques and data. The handbook is produced by the ICSBEP working group, under the aegis of the NEA Nuclear Science Committee.

Find more information online at the ICSBEP website.

Accessing the ICSBEP Handbook

The ICSBEP Handbook and contents are distributed by the NEA Data Bank to named users with a detailed intended use.

Even if you have had access to the online version of the Handbook in previous years, the request must be renewed for each new edition.

Request ICSBEP online here.

Database for the ICSBEP (DICE)

The International Criticality Safety Benchmark Evaluation Project (ICSBEP) released the first version of the Database for the International Handbook of Evaluated Criticality Safety Benchmark Experiments (DICE) in 2001. This database and corresponding user interface is included in the ICSBEP Handbook allowing easier access to information. Selected information from each configuration was entered into DICE, providing a synthetic description of the experiments. These include geometry, fuel composition, moderation and reflection conditions and spectrum characteristics.

Find more information online at the DICE website.

Benchmark models

Recipients of the latest ICSBEP Handbook may be granted access to GitLab repositories containing models for different computer codes that are used to model systems such as those in the Handbook. Users are granted Developer level permissions, allowing them to propose improvements in merge requests. Available computer code model repositories are accessible to authorised users:

If you would like to obtain access to these models, contribute models, or propose other codes that could have model repositories, please contact us at one of the email accounts below.
