DPR-42 50-306 DPR-60 Steam Generator Weld Indication Evaluation During the Unit 2 refueling outage in November-December 1998 Refueling Outage 19, ultrasonic examinations of steam generator #22 were performed in accordance with ASME Boiler and Pressure Vessel Code Section XI. Second period,3'd 10-year interval examinations were done to satisfy the follow-up requirements according to IWB-2420 for flaws identified during the first period,3' ten-year interval and previously submitted for NRC review on May 6,1997. The third ten-year interval plan for Prairie Island was written to conform to the 1989 edition of ASME Section XI.

During the follow-up examinations,32 indications were identified in the tubesheet to channel head weld region for #22 steam generator (see attached cover sheets to examination report #98-0207). One indication (flaw 23) exceeded the allowable flaw

[

size when evaluated against the standards provided in ASME Section XI, IWB-3500.

Accordingly, we performed an analytical evaluation of this flaw per ASME Section XI, IWB-3610. The flaw was found acceptable per this analysis. Attached for your review gf is the result of this evaluation. The procedure used for this evaluation is contained in 77 WCAP-14166 which we submitted for review in January 1995.

Length Length of the flaw T is determined by finding the difference between W1 and W2 for parallel scans.

I W values are from page 2 of the UT report.

Thickness l

Thickness of the component at the location of the flaw r nom wall (circle one).

This value is from page 2,of the UT report.

"t" = 5J inches Calibration The measured angle in the calibration block was 45 degrees Calculations using metal path From page 2 of the UT report, Scan # 3.

l The flaw exhibited 20% DAC at 2.58 and 1.99 inches MP. Max amplitude is at 2.24 inches MP with the transducer exit point at 3.4 inches (W) from the centerline of the weld and 160.5 inches (L) from the 0" 4

reference. (Use of 20% DAC vs. 50% max amp for indications > 100% DAC is conservative.)

Determine correction factor due to curvature.

l Radius = 67.94 (R). Surface distance to max amp point = 1.5840 (C). C/R = 0.0233 TAN.

2)

Determine the lower depth of the flaw from the exam surface.

2.58 (metal path at 20% lower)

• COS of the measured angle 0.7071 = 1.8243 - 0.0204 correction factor = 1.8039 inches depth.

The flaw exhibited 20% DAC at 3.96 and 2.62 inches MP. Max amplitude is at 3.14 inches MP with the transducer exit point at 2.0 inches (W) from the centerline of the weld and 115.5 inches (L) from the 0" reference. (Use of 20% DAC vs. 50% max amp for indications > 100% DAC is conservative.)

! = 0.40 (for all > 0.b t = 5.5 (part thickness) a = 0.20 (surf cCsub su3) circle one)

S = 1.4221 J
