ENCLOSURE BELLEFONTE NUCLEAR PLANT UNIT 1 DEFICIENT DOCUMENTATION FOR CONDUIT FIRE STOPS IN THE UNIT 1 DIESEL GENERATOR BUILDING BLRD-50-438/85-22 NCR 4414 10 CFR 50.55(e)

FIRST INTERIM REPORT Description of Deficiency Conduit fire stop sealing program initiated in the unit 1 diesel generator building was performed under the requirements of Bellefonte Nuclear Plant (BLN) Quality Control Procedure (QCP) 3.5, " Penetration Fire Stops and Pressure and Moisture Seals," and cognizance of the Electrical Engineering Unit (EEU). At the time the seals were installed, temporary identification numbers were assigned to the documentation. After the installation activit; was completed, the Office of Engineering (OE) issued drawings depicting the official identification (reference SDWO816-RZ, -818 RZ series). An unsuccessful attempt was made by BLN personnel to reassign the completed documentation with permanent identification. Therefore, the actual status of the fire stop sealing program is indeterminate.

The apparent cause of the deficiency was due to an excessive overall work load, which caused the activity to not be adequately monitored, and the method of temporary identification was not applied consistently.

Interim Progress BLN Office of Construction (OC) has conducted a sampling of the seals in the unit 1 diesel generator building in accordance with BLN QCP 5.18, "Firestops, Moisture, Pressure, and Radiation Seals," and Military Standard (MIL-STD) 105D to check for cell structure and fill. The sampling identified that additional work will be required to complete the fire stop sealing program.

This will be done in accordance with the applicable site procedures.

TVA will provide additional information on this condition to NRC on or about February 21, 1986.
