SUBJECT:

Ouad Cities Station Unit 2 Cycle 12 Reload and Core Operating Limits Report NBC. Docket No 50 265

Dear Dr. Murley:

Ouad Cities Unit 2, which has recently com leted its eleventh cycle of operation, is currently areparing for Cycle 12 startup stimated startup date is April 7, 1992). The purpose o" th s letter is to advise you of ommonwealth Edison's review of Cyc!o 12 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 10.

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

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

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 12 utilized NRC approved methodologies. The cycle specific power distnbution limits for Cycle 12 are presented in the attachment.

Commonwealth Edison has performed 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 002012 relcad presents no unreviewed safety questions, and that no revisions to the current Ouad Cities Unit 2 Technical Specifications are required as a result of the reload.

. . Dr. Murley April 13,1992 Finally, further verification of the reload core design will be performed during OC2012 startup testing. The startup tests will be consistent with Technical Specifications and testing recommended in Draft Regulatory Guide Task SC 5214. As in the past, a summary of the results of key startup tests will be submitted within 90 days following the resumption of commercial operation.

Based on the previous discussions, CECO has concluded that NRC review and approval of the reload analyses is not required fur resumption of operation with the Cycle 12 core, If there are any further questions regarding the matter, please contact this Very truly yours,
