W have previously considered the withdrawal of material survuillanca specima on a generic basia and have concluded that more meaningful cast results ill be obtained by delaying the removal of test specimens faaetl such ime that the estimated change in ODT temper 4ture is 50*F, but prior to th time when the estimated fluence is 10 13 r./cm' or at the 15 years operat:.onal, interval, whichever first occurs. We, therefore, concur that the Technical Specification requirement to remove the first basket of I.DTT samplea from the reacter vessel during the third refueling outage should be deleted and replaced zita the above mentioned caterial specimen withdrawal program.
