N Praire Island Nuclear Generating Plant Committed to Nuclear Exc e Operated by Nuclear Management Company, LLC L-PI-03-030 April 4, 2003 10CFR50.55a U S Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555 PRAIRIE ISLAND NUCLEAR GENERATING PLANT DOCKET NOS. 50-282 AND 50-306 LICENSE NOS. DPR-42 AND DPR-60 UNIT 2 STEAM GENERATOR (#22) AND PRESSURIZER FLAW EVALUATIONS During the Unit 2 refueling outage in February-March 2002, ultrasonic examinations of steam generator #22 and the pressurizer were performed in accordance with American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Section Xl.
The third interval plan for Prairie Island was written to conform examination of Class 1, 2, and 3 components to the 1989 edition, no addenda, of ASME Section Xl.
For steam generator #22, third period, third interval examinations were done to satisfy the follow-up requirements according to IWB-2420 for flaws identified during the first period, third interval and submitted for NRC review on May 6, 1997 and during the second period, third interval and submitted for NRC review on May 13, 1999. During the follow-up examinations, sixteen flaws identified in the tubesheet to channel head weld region exceeded the allowable flaw size when evaluated against the standards provided in ASME Section XI, IWB-3500. Accordingly, we performed analytical evaluations of these flaws per ASME Section Xi, IWB-361 0. These flaws were found acceptable per these analyses. Attached for your review are the results of these evaluations.
For the pressurizer, examinations were done to satisfy the base examination requirements for the third period of the third interval. During the examination, one indication was identified in the bottom head to shell weld region which exceeded the allowable flaw size when evaluated against the standards provided in ASME Section Xl, IWB-3500. Accordingly, we performed an analytical evaluation of this flaw per ASME Section XI, IWB-3610. This flaw was found acceptable per this analysis. Attached for your review are the results of this evaluation.
The procedure used for these evaluations is contained in WCAP-14166, which was approved by the NRC by letter dated September 6, 1995, addressed to Mr. Roger 0. Anderson, Northern States Power Company.

Determine the depth of the flaw from the exam surface at the maximum amplitude point.
2.981 (metal path at maximum amplitude point)
- COS of the measured angle.5
= 1.490 inches depth.
- 4)
Determine the distance from the center line of the weld to the maximum amplitude point of the flaw 2.981 (metal path at maximum amplitude point) squared = 8.886 (a2) 1.490 (depth at maximum amplitude point) squared = 2.222 (b2) v a2 - b2 = 2.581 inches of surface distance to the flaw from the transducer exit point.
3.25 (Wmax) -
2.581 (surf dist) =.669 inches to the centerline of the weld.
- 5)
Determine S by picking the smaller of the following; S = 1.213 (result of 1) = distance between exam surface and the upper flaw tip
>> OR c<
S =
4.5 (part "t") - 1.7 (result of 2) = 2 distance between the side opposite exam surface and the lower flaw tip
- 6)
Determine 2d in though wall thickness.
1.7 (from step 2)- 1.213 (from step 1) =.487 inches.
Determination of surface or subsurface 0.4d = (2d /2)
- 0.4 =.097 Compare to S (from step 5)
If S is less than 0.4d, the flaw is surface. a = 2d + S = NIA inches.
If S is greater than or equal to 0.4a the flaw is sub-surface. a = 2a / 2 =.243 inches.
I =.80 (for all > 0.5, l = 2a) t = 4.5 (part thickness) a=.25 (surf or sub surf, circle one)
