GINNA NUCLEAR POl<ER PLANT - FIRE PROTECTION By letter to Rochester Gas 5 Electric Corporation dated February 14,
- 1979, we issued a Fire Protection Safety Evaluation Report which supports Amendment No.
24 to License No. DPR-18.
Enclosed is page 3-10 to that report which was inadvertently omitted during printing.

ENCLOSURE (4)
Simultaneous damage to redundant divisions of electrical cables within the same penetrationi Rela Room Halon S stem (5.9)
The licensee will perform a test of the Halon system in the relay room to demonstrate that the design concentration can be attained and maintained for specified period of time.
Electrical Cable Insulation (4.8)
The licensee is investigating the fire characteristics, including the fire resistance of the cable insulation used in the plant.
Electrical Cable Penetrations (4.9.3)
The licensee is reviewing the applicability, to this plant, of the results of electrical cable penetration fire resistance tests which have been performed on materials and construction similar to those being used in this plant.
Specifically, it will be demonstrated that these test results can properly be extrapolated to penetrations of larger sizes and/or different configurations.
Backflow Protection (4.5)
The licensee will review the plant's drain systems and provide backflow protection, to prevent the spread of a possible liquid fire via the drain
- systems, where drains from safety-related areas tie into drains from other areas which contain a large quantity of flammable liquid and which could affect the safety-related area.
Fire Pum Performance (4.3. 1.2)
The licensee will evaluate the operating condition of the fire pumps to determine whether repair or replacement is necessary.
Ex osed Structural Steel (4. 11, 5.5)
The licensee will conduct a study to determine what active and passive systems should be installed to control fires in high fire load areas to prevent structural failures that could jeopardize safe shutdown of the plant.
This study will interface with the safe shutdown study and will be complete in December, 1979.
Fire Bri ade Size (6. 1)
The licensee has proposed a three man fire brigade.
We are not convinced that three men provide sufficient margin for adverse conditions that may occur in the event of a significant fire.
This item is, therefore, unresolved at this time.
The licensee plans to modify his proposal by June 1, 1979.
The final resolution will be addressed in a supplement to this report.
