Description
Verification and validation is a key step in ensuring the quality of nuclear data. However, unexpected inconsistencies are sometimes found in evaluated nuclear data files due to errors during data or file preparation, inadequate assignment of key parameters, and unverified model calculations. While some issues can be identified and corrected prior to official release by means of format checks and macroscopic validation, not all reaction channels of all isotopes can be covered in this process. The present work proposes new methods for isotope-by-isotope consistency assessment using integral damage and heating cross sections. Compared to macroscopic validation, this approach is relatively fast because it does not require neutronic simulations. Moreover, isotope-by-isotope verification complements the typical macroscopic validation, which is mainly sensitive only to certain isotopes. This method is expected to facilitate the establishment of a verified database for damage and heating cross sections, which will enable not only the quantification of radiation damage and nuclear heating but also rapid consistency check of other nuclear data files.
