LIC-14-0109.pdf Fred, This is in regard to the SE for RR-14. Our Engineers have verified that you are correct, the allowable flaw size is 10" in the circumferential direction and 4" in the axial direction. I've highlighted the sentence in the calculation we attached to our August 19, 2014 letter that shows this. See Page 8 of 12 in the Structural Integrity Associates Calculation.

Error in RR-14 (TAC No. MF4643) Importance: High 2The staff is preparing the final written SE for relief request RR-14, dated 8/15/14, and noticed an apparent discrepancy in the submittal.

In the submittal, Attachment 1, page 3, 5th paragraph, the licensee stated that, "-The evaluation concluded, inpart, that the allowable through-wall flaw sizes are greater than 10" in the axial and 4" in the circumferential direction-" There appears to be a discrepancy on the allowable flaw sizes in the previous sentence.

Page 4 of Attachment 2 to the submittal, last paragraph, indicates allowable flaw sizes are 10" in the circumferential direction and 4" in the axial direction. Also, in the 8/19/14 supplement, the licensee's vendor reported that the allowable flaw size should be 10" in the circumferential direction and 4" in the axial direction.

We think the allowable flaw size should be 10" in the circumferential direction and 4" in the axial direction.

Please confirm the discrepancy on page 3 in Attachment 1 of the 8/15/14 submittal, or let me know otherwise. An email is sufficient; I don't think I need a supplemental letter.
