[E Q-v LLNL,has continued?to examine issues involved with burnup credit allowance l detennination in criticality design analysis.
LLNL is not optimistic about

possible..LLNL's: program plan objectives are: 1) to quantify the effects of
<each com)onent 'of burnup credit, 2) to establish the uncertainties' associated f'W, s,j,.,with eac1, 3) to' recommend whatever partial credit for burnup may be
^
' M, attainable as: determined by analysis and verification by measurement of spent Efuel and 4) to examine the impact of misloading of spent fuel.
f
,a I
- c Significant effort in the form of critical experiments with spent fuel, gama 0-c scans of assemblies and of individual fuel rods, and chemical analyses of spent fuel may be necessary to bound uncertainties associated with taking burnup credit allowance.
Such a research effort if pursued by the Department of Energyt is expected to be expensive and lengthy. Original Signed by John P. Roberts John P. Roberts, Section Leader 8910270066 891019 Irradiated Fuel Section NMSS SUllJ Fuel Cycle Safety Branch PNV Division of Industrial and
