A comparative neutronics study showed that there are large discrepancies in the breeding ratios calculated for lithium lead top-ranking fusion blankets with the EFF-1- and ENDF/B-V- based nuclear data libraries. Detailed analysis is still necessary and data testing integral experiments should be employed to identify the deficiencies in these nuclear data evaluations.
