l DOCKET 50-255 - LICENSE DPR PALISADES PLANT

'* Thomas C. Berdine Manager, Licensing NOTIFICATION OF COMPLETION OF ACTIONS - GENERIC LETTER 92-08, "THERMO-LAG 330-1 FIRE* BARRIERS" Consumers Power Company (CPCo) letterdated January 24, 1995, describes proposed corrective actions to bring the Palisades Plant into compliance with Generic Letter 92-08, "Thermo-Lag 330-1 Fire Barriers."

As required by NRC letter dated April 17, 1995, and Generic Letter 92-08, a written response is provided to document completion of all corrective actions associated with Thermo-Lag. This letter provides documentation that all corrective actions described in CPCo letter dated January 24,.1995, have been completed.

In our January 24, 1995 letter, the following corrective actions were proposed.

1.

The Palisades specific corrective action plan tentatively proposed for conduit 1159 was to remove the existing Thermo-Lag barrier and replace the protected circuits with 1-hour fire-rated cable.

2.

The Palisades specific corrective action plan tentatively proposed for conduit 1147 was to remove the existing Thermo-Lag barrier and replace the protected circuits with 1-hour fire-rated cable.

3.

The Palisades specific corrective action plan tentatively proposed for conduit X1885 and its associated pull Uunction) box was to remove the existing Thermo-Lag barrier and embed this conduit and its pull Uunction) box in concrete.

4.

The Palisades specific corrective action plan tentatively proposed for conduit X2402 and its associated pull Uunction) box was to remove the existing Thermo-Lag barrier and reroute the protected circuits outside of the Component Cooling Water Pump Room.

A complete reevaluation of the post fire safe shutdown analysis has determined that a fire in the Screen House [location of conduits 1159 and 1147 (Items 1 and 2 above)] will not cause a Joss of offsite power concurrent with a plant. shutdown. Therefore, the circuits located in conduits 1159 and 1147, which are protected by Thermo-Lag, are not required to function for safe shutdown of the plant. Therefore, the need to protect conduits 1159 and 1147 with Thermo-Lag no longer exists. The Thermo-Lag has been abandoned in place as it provides some level of fire protection thus increasing the overall defense-in-depth for the Screen House fire area.

Conduit X1885 and its associated pull Uunction) box (Item 3 above) have had the Thermo-Lag removed, and the conduit and associated pull box embedded in concrete.

A complete reevaluation of the post fire safe shutdown analysis has determined that the circuits located in conduit X2402 (Item 4 above) are not required to function to obtain hot shutdown of the plant for a fire in the Component Cooling Water Pump Room.

Therefore, the need to protect the circuits located in conduit X2402 no longer exists.

The Thermo-Lag has been abandoned in place as it provides some level of fire protection thus increasing the overall defense-in-depth for the Component Cooling Water Pump Room fire area.
