RRDF-98, and the most recent releases of ENDF/B-VI, JEFF-3.0 and<br />
CENDL-2. Comparisons were also made of the calculated integral crosssection<br />
data with experimental reaction rates in standard neutron fields.<br />
Selection of the best quality cross-section information based on the above<br />
comparisons.<br />
Evaluation and testing of new reaction cross-sections, as requested by the<br />
reactor dosimetry community for extension of the library.<br />
Selection of evaluated and up to date nuclear decay characteristics and<br />
isotopic abundances.<br />
Testing of important dosimetry cross-sections in reference benchmark<br />
neutron fields.<br />
Although the release of IRDF-<strong>2002</strong> and publication of the related<br />
documentation occurred after <strong>2002</strong>, participants attending the second<br />
Technical Meeting decided to retain the title IRDF-<strong>2002</strong>, since the library has<br />
been referred to as this in the open literature.<br />
A CD-ROM containing the full contents of IRDF-<strong>2002</strong> accompanies this<br />
report. Updated versions of this library will also be released by the <strong>IAEA</strong> on<br />
CD-ROM.<br />
1.1. CONTENTS OF THE LIBRARY<br />
IRDF-<strong>2002</strong> contains the best quality data for reactor dosimetry applications<br />
available at the time of preparation. These data include cross-sections and<br />
related uncertainties, nuclear decay parameters for the reaction product nuclei<br />
and abundances of the target nuclides. This is the first time that the decay<br />
parameters and abundances have been presented in the IRDF library.<br />
IRDF-<strong>2002</strong> consists of three main data sets:<br />
(a)<br />
Multigroup data:<br />
(i) Cross-section data for 66 neutron activation (and fission) reactions,<br />
along with uncertainties in the form of covariance information.<br />
(ii) Total cross-sections of three types of cover material, boron,<br />
cadmium and gadolinium, without uncertainty information.<br />
(iii) Radiation damage cross-sections of the following elements and<br />
compounds: iron dpa cross-section (American Society for Testing<br />
and Materials (ASTM) standard E693-01); dpa cross-section for a<br />
special steel composition (Euratom); dpa cross-sections for<br />
chromium and nickel (IRDF-90), for silicon (ASTM standard E722-<br />
94) and for GaAs displacement (ASTM standard E722-94).<br />
