Subject:

LaSalle County Station Unit 2 Unit 2 Cycle 5 Startup Tast Report NFlORocket10 3Z.4

Reference:

July 8,1992 letter from J. Shields to Dr. Murley transmitting the Unit 2 Cycle 5 Startup Test Report Dear Dr. Murley; The referenced letter contains the results of the performance of the LaSalle Unit 2 Oycle 5 Startup Tests, including test LTP-1600-17, Core Power Distribution Symmetry Analysis. The TIP signal symmetry results were shown In Table 3 of the document. Upon further review of this data, it has been determined that the data in the cobmn titled Absolute Difference of BASE #"is incorrect, as it reflects the difference betwean the PASE values for the T!P set performed on May 5,1992. The data should represent tho difference between the average BASE values from each of the two TIP sets.

Attached is a corrected Table 3, to supercede the one originally supplied.

We regret any inconvenience this may have caused your staff. If you have any questions, please call this office.

Respectfully,
