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 4000 MWD /MTV. For Cycle burnups between 4000 MWD /MTU t.c.d EOL burnup, W(z) versus core-height may be obtained through three point interpolation of the data in Figures 8 through 10. 2.5.4 Elevation dependent-W(z)BL values for base load operation between 85 and 100% of rated thermal power with the. Item 2.4.2 specified -target - band about a measured target value at
