DOCKET NOS. 50-445 AND 50-446 TRANSMITTAL OF FIRE Pr 'ECTION REPORT. REVISION 8                         .;
Gentlemen:
i TU Electric, the owner of CPSES Units 1 and 2, herewith submits Revision 8 of the CPSES Fire Protection Report (FPR).                                                        j Enclosed are the following documents:                                                              ;

Revision 8                                original and 10 copies f
A page-by-page description of the changes is attached. The group number                            f assigns a level of significance for each change made to the Fire Protection Report consistent with TV Electric's letter TXX-88467 of June 1,1988. In                         j addition, all changes have been reviewed under the TV Electric 50.59 process                       ;
and found not to include any "unreviewed safety questions *.                                       .
i Pages which do not have technical changes but are included in the revision                         f (because a change shifted the existing material to another page or because                       'i only editorial changes were made to the Fire Protection Report) are not discussed in the enclosure "CPSES FPR Revision 8 Detailed Description".
These changes will not adversely affect the ability to achieve and maintain l
safe shutdown in the event of a fire.                                                            .;
FPR Revision 8 is being issued on December 13. 1993 and will be executed at                        j 12:01 a.m. on December 21. 1993.

Revision         :
The Emergency Diesel Fire pump originally intended to provide lake water as a source of water for the       i Fire Protection-system was abandoned in place as         ;
identified in the Fire Protection Report. To comply      k with Texas Water Commission requirements for             ,
underground storage tanks,.the diesel fuel oil           i storage tank for this abandoned pump has been removed. Thus, the combustible loading data is being revised to reflect this change.
