Subject:

Submittal of Zion Nuclear Power Station Fire Protection Report Amendment 6

References:

(1) Commonwealth Edison (Comed) Company letter,

" Certification of Permanent Cessation of Operations,"

dated February 13,1998 (2) Comed letter, " Certification of Permanent Fuel Removal,"

dated March 9,1998 (3) Comed letter, " Amendment 5 to Zion Fire Protection Report,"

dated November 18,1997 In accordance with the requirements of 10 CFR 50.71(e), we are submitting Amendment 6 to the Fire Protection Report (FPR) for the Zion Nuclear Power Station (ZNPS), Units 1 and 2. In References 1 and 2, we submitted the certifications for ZNPS required by 10 CFR 50.82(a)(1). Therefore, in ,

accordance with 10 CFR 50.71(e)(4), this FPR amendment is being submitted

~

within 24 months of the previous ZNPS FPR amendment which was submitted in Reference 3. Accordingly, this amendment is due to be submitted by November 18,1999.

Attachment 2, " Zion Nuclear Power Station Fire Protection Report Amendment 6," contains Amendment 6 to the ZNPS FPR. As required by 10 CFR 50.71(e), i Amendment 6 consists of replacement pages for the FPR and is accompanied j P

August 26,1999 U.S. Nuclear Regulatory Commission Page 2 by a list of effective pages for the FPR following page replacement. Amendment 6 completely replaces the ZNPS FPR as amended through Amendment 5.  ;

Amendment 6 to the ZNPS FPR presents changes made under the provisions of '

10 CFR 50.59 and 10 CFR 50.48(f), but not previously submitted to the NRC.  !

The changes were made to reflect the permanently defueled condition of ZNPS '

and the amendment includes changes made through July 30,1999. The FPR changes are summarized in Attachment 1, " Summary of Changes." Attachment 1 is provided in lieu of revision bars to indicate changes from the previous version of the FPR due to the extensive revision and reformatting of the FPR.

We have evaluated the FPR changes in accordance with 10 CFR 50.59 and 10 CFR 50.48(f). We concluded the changes do not involve an unreviewed safety question and do not reduce the effectiveness of fire protection for facilities, i systems, and equipment which could result in a radiclogical hazard, taking into I account the current ZNPS decommissioning plant conditions and activities.

As Vice President - Regulatory Services, I certify that the information in this submittal accurately presents changes made since the previous submittal l necessary to reflect information and analyses submitted to the NRC or prepared '

pursuant to NRC requirements, and changes made under the provisions of 10 CFR 50.59 and 10 CFR 50.48(f) but not previously submitted to the NRC.

Pursuant to 10 CFR 50.4(b)(6), one signed original and ten copies of this amendment to the ZNPS FPR are being provided to the NRC Document Control Desk, and one copy to the NRC Region lli office.

if you have any questions about this letter, please contact Mr. P. R. Simpson at (630) 663-7971.
