- 1. Purpose / Objective The objective of this letter report is to provide maximum allowable flaw lengths forjet pump riser pipe circuniferential welds, in order to evaluate and accept indications that may be found during the 1998 outage for Vermont Yankee. Figure 1 is a schematic showing the welds of interest which are labeled Weld 1, Weld 2 and Weld 3.
- 2. Methods The methodology and procedure used in performing the jet pump riser pipe weld flaw evaluation is in accordance with BWRVIP-41 (Reference 1) and the steps are outlined below.
- 1. Determine the loading and load combinations as specified in BWRVIP-41 and calcul..te the membrane and bending stresses considering the load combinations.
- 2. Create a SAP 4G07V (Reference 2) finite element model for the jet pump riser. Anchor connection points are the recirculation inlet nozzle, shroud support plate and riser brace.
- 3. Use the limit load methods of BWRVIP-41 to determine the allowable flaw lengths.
- 4. Calculate IGSCC crack growth for eighteen months (12,000 hrs) cycle based on a growth rate of 5x104inch / hot hour.
- 5. Calculate the crack lengths at which fatigue crack growth due to vibration initiates. This is done by calculating the stress intensity factor (AK) due to flow inductd vibration and comparing it to the threshold stress intensity (Alg) for fatigue crack growth.

- 3. Assumptions ,
- 1. The calculations are based on one flaw per riser. However, synergistic effects of multiple flaws in one riser are negligible and would not affect the results of this analysis.
- 2. Fatigue due to thermal stresses is negligible due to minimal temperature differentials during normal or transient conditions.
- 3. The jet pumps a : =u=d to be in the as-designed configuration because the vibration data on which the fatigue evaluation is based was taken from a new plant in startup. To account for issues such as jet pump fouling and restrainer bracket set screw gap, a l
conservative value of AK threshold, 5.0 ksi-Vin, is used in the vibration fatigue evaluation.
- 4. Allowable flaw lengths are conservatively calculated assuming all welds are flux (SAW)
. welds.
- 4. Loading and Load Combinations 4.1 Loads I Applied loads on the jet pump assembly are described in section 4.1 of BWRVIP-
- 41. The following loads are not applicable or have magnitudes that are negligible j at Vermont Yankee:
i Operating Basis Earthquake Displacements OBED Safe Shutdown Earthquake Displacements SSED Safety Relief Valve SRV Annulus Pressurization AP Condensation Oscillation CO Chugging CHG Displacements during LOCA thermal effects LOCAD 3
GEN:: clear ExerEY GE-NE-Bl3-01935-LTR. Rev.1 4.2 (oad Combinations The load combinations are consistent with the Vermont Yankee FSAR and are in accordance with section 4.2 of BWRVIP-41 except
. The BWRVIP load combination (2) is enveloped by load combination (3) for normal / upset condition. )
. Load combinations (1) through (5) are not applicable for the Emergency / Faulted conditions.
)
- 5. Structural Mechanics Evaluation The limit load methodology as described in section 5.1.1.1 of BWRVIP-41 was used in calculating the allowable flaw lengths. The results based on the application of this methodology are given as allowable flaw lengths.
5.1 Allowable Flaw Length Calculation The flow stress was taken as 3S (S,=16.9 ksi for Type 304 stainless steel at 550 F). As specified in Reference 3, safety factors of 2.77 for the normal / upset conditions and 1.39 for the emergency / faulted conditions, respectively, were used. I The calculated values of the end-of-cycle allowable flaw lengths are tabulated in the following table.
Maximum Allowable Flaw Lengths Based on Outside Diameter Weld Flaw Length (inch)
Weld 1 16.41" Weld 2 18.70" Weld 3 19.58" These allowable values do not consider the crack growth due to IGSCC, fatigue, or NDE uncertainty but are considered in the calculations of the adjusted flaw ,
sizes. l 1
4
GENuclear Energy GE-NE-Bl3-01933-LTR. Rev.1 5.2 Crack Growth Evaluation The maximum required crack growth rate translates into a crack length increase per eighteen months cycle of approximately 0.60 inch at each end of an indication.
Fatigue growth due to flow induced vibration (FIV) is also calculated as per section 5.1.1.2 of BWRVIP-41. With a characterized crack, the stress intensity factor (AK) is computed and compared to the threshold stress intensity factor (AlQ. At (AK) values below AK,3, fatigue growth is neglected. For 304 stainless
~
steel, Reference 3 reports a AKn i value of 5.5-6.0 ksiVin. A threshold value of 5.0 ksiVin is used here to cover vibration loading uncertainties. The allowable crack size due to FIV was based on the stress intensity calculation method described in Reference 3. The smallest calculated EOC crack size for the three locations is 5.4 inches.

If the adjusted flaw length is less than the allowable flaw size (FIV) then the flaw found is acceptable for continued operation without any modification for one cycle.
