Subject:
Quad Cities Station Unit 1 Revised Cycle 13 Core Operating Limits Report NRC Dochet No. 50-254
Reference:
J.L Schrage to T.E. Murley letter dated December 3,1992.
Dear Dr. Murley:
in the referenced letter, Commonwealth Edison (CECO) submitted the Core Operating Limits Report (COLR) for Quad Cities Unit 1, Cycle 13. The purpose of this letter is to provide a revision to that COLR. The revised COLR incorporates a MAPLHGR adjustment factor for single loop o:>eration, and replaces the bundle MAPLHGR curves with lattice specific MAPLH GR tables.
The Quad Cities Unit 1 core, which consists of NRC approved fuel designs, was designated to operate within approved fuel design criteria, Technical 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 al owable 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 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 revised OC1C13 reload presents no unreviewed safety questions, and that no revisions to the current Quad Cities Unit 1 Technical Specifications are required as a result of the reload.

Dr. Murley May 21,1993 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.
Very truly yours, 7
