REFERENCES:

1) Letter from E. J. Bradley (PECO) to H. D. Denton (NRC), " Amendment No. 35 to the License Application for Limerick Generating Station Units-1 and 2." dated June 30, 1982
2) Letter from G. A. Hunger, Jr.- (PECo) to the b NRC, " Changes to the Quality Assurance Program Gescription for Limerick Generating Station, Units 1 and 2," dated November 22, 1989 Gentlemen:

In accordance with.10 CFR 50.71(e)(3)(1) and 10 CFR 50.4(b)(6), this-letter submits one original and ten (10)' copies of the initial (i.e., Revision 0)

Updated Final Safety Analysis Report (UFSAR) for Limerick Generating Station

(LGS), Units 1 and 2. The enclosed UFSAR also contains a revised Quality Z Assurance Program Description which is being submitted in accc, dance with 10 CFR 50.54 (a)(3). Philadelphia Electric Company (PEco) has been in compliance with r the Final Safety Analysis Report (FSAR) update requirements of 10 CFR 50.71(e) since October, 1986-(1.e., 24 months after receipt of the Unit 1 operating

. license), starting with the submittal of Revision 49 to the LGS, Units 1 and 2

-FSAR by our letter dated June 30, 1987. However, as explained below, the-enclosed UFSAR is a complete and new document, incorporating the information from the LGS, Units i and 2 FSAR, through Revision 58, and including changes i made to the station up to January 1, 1989.

. Our letter dated February ll, 1986, as supplemented by our letter dated

' July 28, 1986, requested a schedular exemption from the requirements of 10 CFR 50.71(e) for LGS, Unit 1. Since Unit 2 was still under construction at that time, we requested an exemption allowing the initial UFSAR to be submitted 12 months following the issuance of the Unit 2 operating license. The NRC responded to this request by letter dated December 8, 1987, stating that there was no need for an exemption. This conclusion was based on the determination that the periodic revisions to the LGS, Units 1 and 2 FSAR which we were submitting in accordance with 10 CFR 50.34(b), and our comalteent to include changes to Unit 1 in these FSAR revisions, satisfied the FSAR update  !~

requirements in 10 CFR 50.71(e). Accordingly, we continued to submit periodic revisions to the FSAR during the completion of construction of LGS, Unit 2.

These revisions reflected changes up to a maximum of six months prior to the submittal date and therefore satisfied the requirements of 10 CFR 50.71(e)(4) for Unit 1.

Operating license NPF-83 was issued for Unit 2 on June 22, 1989, and the I last FSAR revision (Revision 58) was submitted to the NRC by letter dated June 29, 1989. This revision included changes made to Unit 1 in accordance with the provisions of 10 CFR 50.59 up to January 1, 1989. Upon issuance of FSAR Revision 58, we initiated preparation of the initial revision of the LGS, Units I and 2 UFSAR as a complete and new document. Submittal of Revision 0 of the UFSAR has been delayed past June 30, 1990, 12 months after submittal of the last FSAR revision, due to the substantial number of sequential tasks that must be accomplished in order to create a complete and accurate UFSAR. 1 We also request that Volume 7A (i.e., Section 38) of the enclosed UFSAR be <

withheld from public disclosure 6s proprietory information in accordance with 10  :

CFR 2.790(a)(4) for the reasons stated in the application and affidavit submitted by Pennsylvania Power and Light Company and cited in the Reference 1 submittal.

This initial UFSAR has been prepared in accordance with 10 CFR 50.71(e) and the guidance provided in NRC Generic Letter 81-06, " Periodic Updating of the j

Final Safety Analysis % ports (FSARs)." dated February 26, 1981, to include the following.

1. Provision of an initial UFSAR that is a clean document without change bars or revision numbers.
2. Incorporation of the appropriate portions of PECo responses to NRC FSAR questions into the body of the initial UFSAR.

In addition, the following changes have been incorporated into the initial UFSAR.

1. The Fire Protection Evaluation Report (FPER) for the LGS, Units 1 and 2 was included in Section 9A of the UFSAR.
2. The non-proprietary Design Assessment Report (DAR) for the LGS, Units 1 and 2 was included in Section 3A of the UFSAR.

i,

, Document Control D3sk August 24, 1990-Page 3 3.- The proprietary DAR:for LGS, Units 1 and 2 was included in Section'38 of the UFSAR.

4. The initial UFSAR incorporates a number of editorial changes. These changes were to correct spelling and typographical errors; to correct references to UFSAR sections, tables = figures, or table of contents; to improve grammar or clarity without changing meaning; to move i information to more appropriate locations; or to make certain UFSAR-sections consistent with other UFSAR sections.
5. The UFSAR reflects changes made to LGS, Units 1 and 2. .nder the provisions of 10 CFR 50.59, up to January 1, 1990.
6. The Quality Assurance Program Description (i.e., Section 17.2-of the UFSAR) reflects editorial and organizational changes and also includes changes described in Reference 2. These changes are- i submitted in accordance with 10 CFR 50.54(a)(3) and do not reduce the  ;

cossaiteents in the Quality Assurance Progsas Description previously i accepted by the NRC.

As required by 10 CFR 50.71(e)(2)(i), I certify that to the best of my knowledge, the initial UFSAR accurately reflects information and analyses-submitted to the NRC, or prepared pursuant to NRC requirements since the submittal of Revision 58 to the FSAR, Revision 12 to the FPER, and Revision 11 to the DAD - Also,asrequiredby10CFR50.71(e)(2)(ii).theAttachmenttothis letter identifies changes made under the provisions of 10 CFR 50.59 and included in the enclosed UFSAR. Revision 0, but not previously submitted to the NRC.
