Dear Mr. Denton:
This letter is to inform you of Commonwealth Edison's intent to implement the Fire Damper Surveillance Program submitted to you in reference (d). - The visual inspection of fire dampers will continue to be' implemented in accordance with T.S. 4.7.6.1.
A periodic operability test of fire dampers separating redundant safe shutdown equipment and those within the fire barriers of the control room and Auxiliary Electric Equipment Room will be-conducted in accordance with and on the schedule indicated in reference (d).
Commonwealth Edison continues to believe that fire dampers which are initially tested for operability to' verify correct installation can be aintained. operable throughout their lifetime by use of visual inspections -
m alone. However, if fire damper operability tests are to be required, we _
i
- believe this program is superior to other programs now under consideration in support of generic requirements. We. stand ready to meet with your staff on a mutually agreeable schedule to further discuss this matter. We would appreciate the opportunity to present our position to the CRGR at the time such generic discussions are provided by the staff.
