, Attachment to ICAN079903 Page1of14 ADDENDUM B TO BAW-2346P, REV. 0 ANO-1 PLANT SPECIFIC MSLB LEAK RATES (NON-PROPRIETARY)
This addendum provides plant specific accident condition leak rates for Arkansas Nuclear One, Unit 1 (ANO-1). The leak rates are intended to replace the generic bounding accident leak rates. These plant specific leak rates are based on the thermal and structural response of the steam generators associated with the plant specific main steam line break (MSLB) thermal hydraulic analysis results. Although the results of this appendix are based on leak testing and methodology developed as part of a Babcock and Wilcox Owners Group (B&WOG) proprietary program, the actual results of this Appendix are specific to ANO-1 and therefore are not considered B&WOG proprietary.
B.1 METHOD OF ANALYSIS The method of analysis used for determining plant specific leak rates is identical to that outlined in Topical Report BAW-2346P. Tne ANO-1 MSLB loads are determined and applied to define the tube-to-tubesheet bore A dilations. The tube-to-tubesheet bore A dilations are used with the results from the mockup leak tests to determine the leak rates as a function of tubesheet radius.
The ANO-1 plant specific tube loads and associated A dilations as a function of tubesheet radius are summarized in Table B-1 for the intact steam generator and in Table B-2 for the broken steam generator. The tube leakage is addressed in Section B.2.

Attachment to 1CAN079903 Page 6 of14 B.2 ANO-1 MSLB LEAK RATE VS, TUBESHEET RADIUS The A dilation versus tubesheet radius values from Tables B-1 and B-2 are used to determine the ANO-1 plant specific MSLB accident leak rate versus tubesheet radius.
The A dilation that resulted in the least amount of contact pressure was used to determine the leak rates as a function of tubesheet radius (i.e. the tube defect was assumed to align in the direction of the worst case A dilation). The smallest contact pressure, and therefore largest leakage, occurs at the largest positive A dilation. For the cases where both the circumferential and radial dilations are negative (compressive), the least negative A dilation was used. The worst case dilations from Table B-1 and Table B-2 were used to select the appropriate leak rate. Leak rates were determined based upon leak rate testing at the corresponding A dilation and accident condition AP.
A summary of the limiting A dilations and resulting accident leak rates for the intact steam generator is contained in Table B-3 and also in Figures B-1 and B-2. A condensed numerical summary of the leak rates is provided in Table B-4.
A summary of the limiting A dilations and resulting accident leak rates for the broken ,
