International Reactor Dosimetry File

The objective of the project is to prepare and distribute a standardised, updated and benchmarked evaluated cross section library of neutron dosimetry reactions with uncertainty information (IRDF-2002) for use in lifetime management assessments of nuclear power reactors and other applications.

Within the scope of the project the following tasks were considered:

• Intercomparison of reactor dosimetry cross-section data and their uncertainties in various libraries including IRDF-90.2, JENDL/D-99 and RRDF-98.
• Reaction rates in a standard neutron field were compared. Select best data based on the above comparison of data for IRDF-2002.
• Evaluate and test new reaction cross sections requested by the reactor dosimetry community for extension of the database. Include evaluated decay radiation characteristics in the files.

Comparison of experimental and calculated fission and thermal spectrum averaged cross sections.

Quality LevelExplanation of Terms

• Authoritative: All information in the resource has been verified by authorities as indicated.
• Quality-checked: All information in the resource has been quality-checked as indicated.
• Not quality-checked: Although the information in the resource may come from peer-reviewed journals or other high-quality sources, it has not undergone subsequent quality checking before incorporation in the resource.

: Quality-checked by the IAEA Secretariat Evaluated data
CompletenessExplanation of Terms

• Comprehensive:The resource includes all items in the category for which the resource was created.
• Selective: The resource includes only selected items in the category for which the resource was created, with the process or basis for the selection as indicated.

: Comprehensive
Update FrequencyExplanation of Terms

• Updated continually: A conscientious effort is made to add new information immediately and keep the resource up-to-date on a day-by-day basis.
• Updated periodically: The resource is updated on a schedule. Common values are monthly, quarterly, annually or biennially, but others are also used.
• Updated occasionally: The resource is updated now and then, but not on a schedule.
• Static: The resource is a one-off creation with no plans for updates, or a resource that was updated in the past but has now been frozen with no new input planned.
