Subject:

Fire Protection Prohnhilistle Risk Assessment, AllWR SSAR drall Appendix 19h1

Reference:

1. SIICY 9b309, dated October 1,1991

2. Fire Protection Probabilistic Risk Assessment, AllWR SSAR draf t Appendix 19M, Proprietary Information, MFN No.

144 91, dated November 12,1991

3. Submittal of Amendment 4 to Gli's AllWit SSAR MFN No.

005 89, dated January 31,1989 Enclosed are thirty four (34) copics of the dralt writeup for the Fire Protection PRA as requested in the Draft Safety livaluation Report on the AllWR PRA (Reference 1). This draf t was performed based on the same methods and models used for the original Pila (iteference 3). As a result of design changes that have occurred since that PRA submittal, the PRA model will be revised to reflect these changes and a new Pila, including Fire Protection, will be submitted next year. The results of the updated Fire Protection l'RA are not expected to be significantly different from the draft results contained in this submittal.

A major portion of the subject material contains information that is designated as General lilectsic Company proprietary information and is being submitted under separate cover (Reference 2).

It is intended that GE will amend the SSAll to include this information when it is finalized.

Sincerely, O
