Global Assessment of Nuclear Data Requirements

Global Assessment of Nuclear Data Requirements or GANDR is a IAEA Nuclear Data Section Data Development Project.
It is a set of computer programs which generate correlation matrices which rank the accuracy of various types of nuclear data. In judging the adequacy of the nuclear data used as input to design-relevant neutron transport calculations, one finds that there is a very complex relationship between the accuracy of the input data and the accuracy of the calculated results.
We conclude that GANDR is now fully practical on a modern computer in the desktop class. A major outcome of this development work is that a functioning and practical prototype of the GANDR system is now available in the IAEA Nuclear Data Section.
