ANO-1 Cycle 19 COLR Arkansas Nuclear One - Unit 1 Docket No. 50-313 License No. DPR-51

Dear Sir or Madam:

Arkansas Nuclear One -

Unit 1 (ANO-1) Technical Specification 5.6.5 requires the submittal of the Core Operating Limits Report (COLR) for each reload cycle. Attached is Revision 0 of the ANO-1 Cycle 19 COLR. Please note that the approved revision number of the Babcock and Wilcox Topical Report BAW-10179P-A is identified in the COLR as August 2001. This completes the reporting requirement for the referenced specification.

This submittal contains no commitments. Should you have any questions, please contact David Bice at 479-858-5338.

Sincerely, Timothy G. Mitchell Director, Nuclear Safety Assurance TGM/dbb

> 60% FP) and to 2.19% (power levels 5 60% FP) at the earliest time-in-life that this assumption is no longer valid.

The present T-H methodology allows for an increase in the design radial-local peak for power levels under 100% full power. The equations defining the multipliers are as follows:

I P/Pm = 1.00 P/Pm < 1.00 I MAP Multiplier I

1.0 1 + 0.3(1 - P/Pm) I Where P = core power fraction, and Pm = 1.00 for 4-pump operation, or

= 0.75 for 3-pump operation 26
