Global Assessment of Nuclear Data Requirements

The Global Assessment of Nuclear Data Requirements (GANDR) is a set of computer programmes that generate correlation matrices which rank the accuracy of various types of nuclear data. 

There is a very complex relationship between the accuracy of input data and the accuracy of the calculated results when judging the adequacy of nuclear data used as input to design-relevant neutron transport calculations. GANDR was developed by the IAEA Nuclear Data Section to tackle this issue.
