Mr. J. S. Perry Site Vice President Dresden Station Commonwealth Edison Company 6500 North Dresden Road Morris. IL 60450 February 10, 1997

SUBJECT:

DRESDEN CONFIRMATORY ACTION LETTER CCAL) MEETING

Dear Mr. Perry:

This refers to the meeting conducted in Region III on January 31. 1997. This meeting was to discuss your progress in completing actions outlined in the Confirmatory Action Letter (CAL) No. RIII-96-016. Topics discussed included your progress in completing the actions outlined in the CAL and other improvement initiatives.

Attached to this letter are the materials your staff presented during the meeting.

Your staff indicated that on the slide titled. "PIFs:

Potential Discrepancies." the bull et that stated. "The Number of Cells for 250 V Batteries Different in TSUP and UFSAR." should instead state. "The Number of Cells for 250 V Batteries Different in DBD and UFSAR."

In accordance with Section 2. 790 of the NRC's "Rules of Practice." Part 2.

Title 10. Code of Federal Regulations. a copy of this letter will be placed in the NRC's Public Document Room.

We appreciated your cooperation in this matter.

If you have any questions regarding this meeting, please contact me at 630/829-9603.
