Core Operating Limits Report for Quad Cities Unit 1 Cycle 17A

Letter from USNRC to J. L. Skolds (Exelon) dated, July 29, 2002 "Quad Cities Unit 1 - Issuance of Amendment RE: Change in Minimum Critical Power Ratio Safety Limit (TAC NO. MB4747)

The referenced letter amended Quad Cities Unit 1 Minimum Critical Power Ratio Safety Limit to allow for operation to the end of cycle 17A. On January 9, 2002, Quad Cities Nuclear Power Station (QCNPS) Unit 1 was forced to shutdown (Q1 F49) as a result of a failed jet pump. During the forced shutdown QCNPS replaced a leaking fuel bundle with a bundle from the spent fuel pool, and elected to shuffle additional fuel bundles to extend full power operation for the Unit 1 core. As a result, Cycle 17A has been developed for Unit 1. This revised COLR is applicable until the end of Cycle 17A, which ends in November of 2002.

Enclosed is the revised COLR for Cycle 17A, submitted in accordance with Technical Specifications Section 5.6.5.d.

Should you have any questions concerning this letter, please contact Mr. W. J. Beck at (309) 227-2800.

(Technical Requirements Manual 2.1.a.1 and Bases of TS 3.2.2)

3. During off-rated flow conditions in Automatic Flow Control Mode, the Operating Limit MCPR for each fuel type at a specific core flow condition shall be determined from Table 4-3, Table 4-4, or Table 4-5 using the appropriate operating conditions. PercentRated Core Flow based on 98 MLB/hr with 108% Maximum Flow in Automatic Flow Control Operation(Technical Requirements Manual 2.l.a.1 and Bases of TS 3.2.2).

4. During PLU Out of Service Conditions a 0.980 MFLCPR Administrative Limit shall be used.
