Subject:

Zion Nuclear Power Station Units 1 & 2 Proposed Amendment to Facility Operating License Nos. DPR-39 and DPR-48 Containment Isolation System NRC Docket Nos. 50-295 and 50-304

Dear Mr. Denton:

Attachment I to this letter is a proposed amendment to Facility Operating License Nos. DPR-39 and DPR-48, Appendix A, Sections 3.9 and 4.9 -

Containment Isolation Systems. This proposed amendment expands the contain-ment isolation valve listing based upon information contained in Zion Station's FSAR. In addition, this proposed change removes guidance involving 3-loop operation and generally incorporates the guidance contained in NUREG-0452, Rev. 4. A more detailed description of this proposed amendment is contained in Attachment 2.

Attachment 3 contains Commonwealth Edison Company's demonstration that this proposed amendment does not involve a significant hazards consideration. This change has received on-site and off-site review and approval.

A $150.00 remittance is enclosed in accordance with 10 CFR 170. As provided by 10 U/R 50.91, the State of Illinois is being notified of this amendment request by transmittal of a copy of this letter and the attachments.
