==Dear Mr. Ziemann:==
 
During conversations with members of the NRC staff, a revue'st" was made for data                  taken during the startup of Cycle 7 at the R. E. Ginna Plant.                    This data reflects measurements taken with control rod LS operating as a D bank rod and rgd K7 operating as an A bank rod. Figure 1 illustrates the F                             obtained from the Incore reduction of Flux Map VII-3 which Rs take with the rods as described above. Figure 2 illustrates the F>HIs with the rod swap corrected.
Also attached is a table which presents the predicted rod worth and the measured rod worths with and without control rods LS and K7 swapped.
Very truly yours, L. D. White, Jr .

Dear Mr. Ziemann:

During conversations with members of the NRC staff, a revue'st" was made for data taken during the startup of Cycle 7 at the R. E. Ginna Plant. This data reflects measurements taken with control rod LS operating as a D bank rod and rgd K7 operating as an A bank rod. Figure 1 illustrates the F obtained from the Incore reduction of Flux Map VII-3 which Rs take with the rods as described above. Figure 2 illustrates the F>HIs with the rod swap corrected.

Also attached is a table which presents the predicted rod worth and the measured rod worths with and without control rods LS and K7 swapped.

Very truly yours, L. D. White, Jr .
