The tritium production was determined for samples of lithium carbonate containing high enrichments of /sup 6/Li(96%) and /sup 7/Li(99.9%). The measured data were used to check the accuracy with which the TPRs could be numerically predicted using current nuclear data and calculational methods. The numerical predictions from tritium production from the /sup 7/Li samples agreed within the experimental errors of the measurements, but /sup 6/Li measurements which differ by more than 20 per cent from the predicted values were observed in the lower half of the assembly.
