SRE CRITICALITY CALCULATIONS
Technical Report
·
OSTI ID:4265818
The formulas and constants used in calculating the critical enrichment for a hot, clean, equilibrium xenonand samarium-poisoned 31-cell SRE core are presented. The results of this caiculation may be considered somewhat pessimistic since, where uncertanties arose, they were resolved to favor a higher enrichment, This is not to say, however, that there has been a departure irom the accepted formuias, rather, it points to the number of judicious choices one must make to perform this type of calculation. The enrichment obtained for the conditions cited is 2.45 atomic pereent, It is estimated that this enrichment should be raised to 2.8 at.% to account for control rods, thimbles, safety rods, and burnup.
