Subject:

Quad Cities Station Unit 2 Revised Cycle 13 Core Operating Limits Report NHQDocket No. 50-265

Dear Dr. Murley:

Quad Cities Unit 2, which has recently completed its twelfth cycle of operation, is currently preparing for Cycle 13 startup (estimated startup date is May 26, 1993). The purpose of this letteris to advise you of Commonwealth Edison's review of Cycle 13 reload under the provisions of 10CFR50.59 and to transmit the Core Operating Limits Report (COLR) for the upcoming cycle consistent with Generic Letter 88-16.

The Quad Cities Unit 2 core, which consists of NRC aaproved fuel designs, was designated to operate within approved fuel design criteria,"rechnical Specifications and related bases such that:

Core operating characteristics will be equivalent to or less limiting than those previously reviewed and accepted; or

- reanalysis has been performed to demonstrate that the limiting postulated FSAR events which could be affected by the reload are within allowable limits.

Consistent with past reloads, the reload licensing analyses performed for Cycle 13 utilized NRC approved methodologies. The cycle-specific power distribution limits for Cycle 13 are presented in the attachment.

Commonwealth Edison has periormed a detailed review of the relevant reload licensing documents, the associated bases, and references. Based on that review, a safety evaluation was prepared as required by 10CFR50.59 and has been approved by CECO's On-Site and Off-Site Review functions. CECO has concluded that the revised OC2C13 reload presents no unreviewed safety questions, and that no revisions to the current Quad Cities Unit 2 Technical Specifications are required as a result of the reload.

Finally, further verification of the reload core design will be performed during OC2C13 startup testing. The startup tests will be consistent with Technical i Specifications and testmg recommended in Draft Regulatory Guide Task SC 521-4. As in the past, a summary of the re' alts of key startup tests will be submitted within 90 days following the resumption 0; ;ommercial operation.

Based on the previous discussions, CECO has concluded that NRC review and approval of the reload analysis is not required for resumption of operation with Cycle 13 core.

If there are any further questions regarding the matter, please contact this office.

I Very truly yours, >
