Dear Mr. Denton:
Reference (a) provided Commonwealth = Edison's commitment to install six inch thick removable concrete plugs for the equipment
' hatches located at elevation 426', near 12-Q and at elevation 364',
near 18-N in the Braidwood Auxiliary Building to provide appropriate fire protection measures at those locations.
The purpose of this letter to provide you with our plans for the other equipment hatches in the Auxiliary Building which are directly above the hatch at 364'.
Specifically, Commonwealth Edison intends to install concrete plugs for the hatchways at elevations 383' and 401', in the Auxiliary Building prior to Fuel Load of Braidwood Unit 2.
Access
-through these equipment hatches will be necessary to facilitate the completion of Unit 2.
Upon installation of these concrete plugs they will'be caulked in place with a fire resistant type of caulk.
As presented in reference (a), Commonwealth Edison station personnel have implemented hourly fire watches as a compensatory measure until the hatchways are sealed.
Also, Commonwealth Edison will take compensatory measures in the future when it becomes necessary to remove the concrete plugs.

Also, automatic sprinklers have been installed immediately below the floor at elevation 364' to provide appropriate fire protection measures for the stairwell leading to elevation 346'.
Please address any questions concerning this matter to this office.
