BOL (0 - 4000 MWD /MTU) :+ or - 5% about a i measured target value MOL (4000 - 10000 MWD /MTU) :+ or - 5% about a measured target value
.EOL (10000 - 18000 MWD /MTU): + or -

This information is sufficient to determine W (z) versus core height in the range of 0 MWD /MTU to EOL burnup. Three point interpolation of the data in Figures 7 through 9 is sufficient to determine RA00 W(z) versus core height between a Cycle burnup of 0 to
