AN IWB 3640 EVALUATION OF INDICATION DETECTED AT ltECillCULATION DISCil ARGE SAFE END D
Background
During the examination of the Oyster Creek Unit I weld No. NR02 2-565D (NG D-23), an axially oriented planar indication was recorded by the SM ART 2000 system. T'.e indication has been characterized as a weld defect. The details of the indication characterization are given in Appendix A. The objective of this writeup is to report the results of the evaluation of this indication per the procedures of Paragraph IWB 3640 of ASME Section XI. Safrfnd Geomg11ylDILIDilication Characterizati.gn The safe end geometry is shown in Figure 1. The indication is located ints a safe end = 2 inches from the nozzle weld. The nominal thickness of the safe end r. this location is 1.625 inches, excluding the clad thickness. However, the UT me.as' .ements show the thickness at this location to be = 1.5 inch. Therefore, a thickness of 1.5 inch was used in the calculation. The indication is primarily axial in orientation but has some circumferential component. Initially, the indication was sized using the UT procedures for detecting IGSCC. The initial UT report (Appendix A) states the deepest point of the indication to be at 45% throughwall and that the indication may be connected to the inside surface. However, a subsequent review of the UT results (also included in Appendix A) led to the conclusion that it was a subsurface indication and that it was not an IGSCC. Since this indication has been characterized as a subsurface, it is not expected to be in contact with reactor water. Thus, only the fatigue crack growth need to be considered in calculating the final indication size. Since this indication was characterized as non-lGSCC, it was also sized using the ASME Section XI procedures. The results are shown in Appendix B. The following summarizes the indication dimensions as used in this evaluation: 1

Based on IGSCC Proced. Based on Section XI Orientation Length Depth Length Depth (in.) (in.) (in.) (in.) Circumferential 0.3 0.875 0.4 0.65 Axial 0.9 0.875 0.9 0.65 The IGSCC based procedure depth of 0.875 inch in the above table conservatively includes estimated clad depth of 0.2 inch. Apulitd_Sness Marnitudes The applied loads from weight, seismic and thermal expansion loadings were supplied by GPU Nuclear (Appendix C). Based on these loads, the calculated stress magnitudes are the following: Load Type Magnitude (ksi) Weight 0.57 OBE 0.70 SSE 1.22 Thermal Expansion 0.22 Pressure 5.58 (Axial) 11.17 (hoop) QagkGrowth Evaluation Since the subject indication is subsurface, the only mechanism that would produce suberitical crack growth is fatigue cycling. A fatigue crack growth relationship for air environment is appropriate for this case. The results of a comprehensive study, sponsored by the Metals Properties Council (MPC), of the fatigue crack growth behavior of various stainless steels used in nuclear applications (e.g., wrought and cast type), were published in Reference 1. The following relationship is provided in Reference 1: 2
da/dN = CeFeS*(AK)3.3 (1) where, C = Temperature Factor F = Frequency Factor S = R Ratio Factor AK is in psVin units, and da/dN is in in./ cycle. The values assumed for these variables in this evaluation are: C = 2x10-20, F = 5, and S
= 2. The subject indication is away from the nozzle to safe end weld but some residual stresses may be present from the application of cladding. Therefore, the selection of 2.0 as the value for parameter S (corresponding to an R Ratio of = 0.6) is reasonable.
The largest AK is expected to be for the axial indication which is subjected to hoop stress due to pressure loading. The 4K value was calculated using the following equation from Appendix A of Section XI (Reference 2): AK = ao e Mme V(wa/Q) (2) For the subject indication geometry, the values for Mm and Q are 1.1 and 2.2, respectively. Given that ao is 11.17 ksi, a = 0.875 in., the 4K value was calculated as 11.73 ksVin. The cyclic event assumed was pressurization to 1250 psi and back to zero pressure. Substitution of the preceding numerical value of AK into equation (1) gives a predicted fatigue crack growth of = lx10-5 n./ i cycle. Even if we very conservatively assume 100 events per fuel cycle, the preceding rate gives a crack growth of only 0.001 inch or 1 mil. This indicates that the fatigue crack growth of this indication is expected to be insignificant. IWil 3640 Evaluation Results for Circumferential Component of Indicaliga The material specified for the safe end is SA 336, forging Type 316. The ASME Code Sm value for this material @ 550*F is 17.5 ksi. Since the indication is located in the safe end base metal, only the primary loads such as pressure, weight and seismic inertia need - 3-
be considered in determining the allowable Haw size. Since the seismic inertia stresses area small fraction of the total primary stress, the Normal (i.evel A) and Upset (Level B) conditions criteria are expected to govern. Thus, the allowable flaw sizes will be determined using Table IWB-3641-1. The (Pm+P b )/S ni ratio for the Level A and B conditions is 0.39. The least value for this ratio is 0.6 in Table IWB-3641-1, and was conservatively used. Figure 2 shows the IWB-3640 allowable flaw sizes and the subject indication. The indication is plotted both ways, one using the IGSCC based dimensions and the other using Section XI based sizing. It is seen that in either case the indication is well below the acceptable values. IWB 3MO Evaluation Results for Axial Component ofIndication The allowable flaw sizes in this case are determined from Table IWD 3641-3. The Pm/Sm ratio at the safe end is 0.64. Therefore, the allowable flaw sizes corresponding to ratio of 0.7 were used from the table. Figure 3 shows the results of this evaluation. Again both the IGSCC based dimensions and the Section XI based dimensions are plotted, 11 is seen that in this case also the indication is well within the acceptable flaw size curvc.. Discussion Based on the preceding evaluation per the rules of IWB-3640, ASME Section XI, operation as-is can be justified for more than one fuel cycle. A key basis for this conclusion is that the predicted fatigue crack growth per fuel cycle is insigniGeant. Therefore, to assure that the growth of this indication is insignificant during the future plant operation, as predicted by the analysis, it is recommended that this indication be reinspected at least during the next refueling outage. Should that inspection bear out the analytical prediction, the subsequent icinspection interval can be increased to every alternate refueling outage. Conclusion Based on the results of evaluation per Paragraph IWB-3640 of ASME Section XI, it is concluded that the subject indication is acceptable for operation as-is of the safe end for at least the next fuel cycle.
