Quad Cities Nuclear Power Station Unit 1 Cycle 12 Reload and Core Operating Limits Report IMCJnche.Lifouh0-2B .___

Dr, Murley:

Quad Cities Unit 1, which has recently ccmpleted its eleventh c'Icle of -

operation, is currently areparing for Cyc\e 12 startup (estimated startup date is February 2, 1991). T1e purpose of this (Jtter is to notify you of the Commonwealth Edison Company (CECO) review and approval of the Cycle 12 reload

, under the provisions of 10 CfR 50 59, and to transmit the , attached Core Operating Limits Report (COLR) for the upconing cycle consistent with Generic Letter 88-16, The Technical Specification amendment to incorporate the COLR for Quad Cities Unit 1 was previously apprcived in the referenced letter.

The Quad Cities 1 Cycle 12 core, which consists of NRC approved fuel designs developed by General Electric Company, was designed.to operate within approved fuel design criteria, Technical Specifications and related bases such that:

- core operating characteristics will be ettuivalent to or less limiting than those previously reviewed and accepted; or

- reanalysis has been performed to demonstrate that the 1(miting postulated FSAR even't which could be affected by the reload are within allowable limits.

Consistent with past reloads, the reload licensing analyses performed fo.

Cycle 12 utilized NRC approved methodologies. The cycle-specific 4ower distribution limits for Cycle 12 are presented ln the atttched COLR.

i. single bundle lifetime roannels has been addressed consistent witn the General

Electric generic methodo'ogy, which adjusts the R-factors. for the ful in the  !

core monitoring software.

i CECO has performed s detailed reviow of the relevant licensing 1 docanents, the associated 7ues and references. Based on that review, a l

tafety evalvHlon was preN ed q required by 10 CFR 50.59 and approved by Ceco's On + ~ off-Si te Review functions. Ceco has concluded that the reload pre. unrevf nud safety. questions, and that<no revisites to the current im..,.,, M Spelfications are required as a result of the relu f rinally, further verification of the reload-core design will Sv performt, during startup testing. The startup tests will--be consistent scul'  !

Task SC 521-4. As l' thb (,1sti a- summary of the results of key startup _tesu: ,

will be submitt A witlin 90 #6s following the resumption of-commercial operation.

Based on the previous etitussion, CECO has concluded that-NPO-review l and approval of the cycle-53eck ic reload analysis is not required for resamption of operation wita tN Cycle 12 core.
