Dear Mr. Ziemann:

During conversations with members of the NRC staff, a request was made for additional detail on the flux maps taken during the startup of Cycle 8. Attached are five figures which illustrate measured assembly powers and a com-parison between measured assembly power and the predicted assembly power for the following conditions: pter~

a. Hot Zero Power, All Rods Out (Figure 1)

b. Hot Zero Power, D bank in (Figure 2)

c. 25% Power (Figure 3)

d. 50% Power (Figure 4)

e. 80% Power (Figure 5) gJ Q Very truly yours, C~~
