COMMONWEALTH EDISON COMPANY CALCULATION NO. NED-P-MSD-089 PAGE NO. 4 Purpose / Objective:

The purpose of this calculation is to evaluate the flaw detected in weld 02AS-F2 on Quad Cities Unit 1 Recirculation A loop pump suction line. This flaw was found during the augmented IGSCC inspection program, which is based on NRC GL 01. The flaw exceeded the applicable acceptance standards for austenitic steels delineated in IWB-3514 of the 1989 ASME Section XI Code, Reference 1, and is evaluated using the methodology and acceptance criteria specified in Reference 1, IWB-3640, to establish its acceptance for continued service.

Methodology and Acceptance Criteria:

The piping report, Reference 4, identifies the material used for the piping containing the flaws as SA358 Gr 304 austenitic stainless steel. Therefore, the evaluation and acceptance requirements of IWB-3640 are applicable to the evaluation of this flaw.

The rules of IWB-3641 of ASME Section XI,1989 Edition are applicable because the following conditions are met:

(a) Piping / fitting NPS 2: 4 with the flaw within Vrt of the wefd.

(b) Piping / fitting materials are made of wrought stainless steel, Ni-Cr-Fe alloy.

(c) Materials have a specified minimum yield strength less than 45 ksi.

(d) Material Sm values are given in Table 1-1.2 of Section Ill,1989 Edition.

As required in lWB-3641 of Reference 1, flaw growth analyses are performed on the flaw to determine the maximum growth due to fatigue and stress corrosion cracking mechanisms for an evaluation period of at least four (4) operating years (35040 hours). The calculated maximum flaw dimension at the end of the evaluation period is compared with the calculated maximum allowable flaw dimensions for both normal operating / upset conditions and emergency / faulted conditions to determine the acceptability for continued service.

l COMMONWEALTH EDISON COMPANY CALCUl.ATION NO. NED-P-MSD-089 PAGE NO. 5 The flew growth analyses are perfonned for fatigue crack growth following the methodology of Reference 1 Appendix C and for IGSCC following the methodology of NUREG-0313, Reference 6. The fatigue crack growth is based on the normal / upset operating events expected to occur during the evaluation period with the transient definition and transient stresses developed for Dresden Unit 3 Recirculation system used in this evaluation. The IGSCC crack growth rate is developed using the residual stress distribution and operating loads with the da/dt relationship defined in Appendix A of Reference 6. The evaluation period for the flaw growth analyses was determined as the time necessary for the flaw depth to grow to approximately the IWB-3640 acceptable depth limit.

The bounding normal / upset and emergency / faulted design basis load combinations are used to define the applied stress values used in this evaluation. These bounding applied stress values are used to establish the acceptable crack size which must be greater than the end of evaluation flaw size. Because these flaws are located adjacent or within the weld material as defined in Figure IWB-3641-1 of Reference 1, the critical flaw size is defined using the criteria for a submerged arc weld, SAW.

Assumptions:

1) Quad Cities Unit 1 and Dresden Unit 3 recirculation system pressure and thermal transient responses to normal / upset transient events are identical. This is a reasonable assumption because both units are fabricated from materials with identical material properties for thermal expansion and from identical fitting geometries, and are operated using similar procedures.
2) The welding process used to fabricate this weld is conservatively defined as SAW, submerged arc weld.
3) Five startup/ shutdown events were assumed to occur during the evaluation period with a single idle loop restart occurring between each startup and shutdown. While this places some limitation on operation over the next fuel cycle, the fatigue crack growth st:xiies show that fatigue crack growth is minimal.

Thus, this limitation can be reevaluated if the 5 cycle limit is approached.

Materials:

As defined in Reference 3, the flaw is located on the pipe side of the weld. The material for this fitting is SA358, Gr 304. From Reference 2, Sm for this material is 2

IGSCC Crack Growth Calculation for the Loop A Recirculation Pump Suction Weld 02AS-F2:

l i

The crack growth due to IGSCC is calculated using the previously calculated residual stress and the I

circumferential flaw. The crack growth rate, da/dt = 3.590 x 104 K,2.tet in/ hour, specified in NUREG-0313.

i Reference 6, was used to project the flaw depth. The calculations, documented in Attachment C, were performed using the PC-CRACK program, Reference 8.

After 44000 hours, the flaw grows from 0.252" to a depth of 0.602" as a result of stress corrosion crack growth which produces an a/t ratio of 0.467. As recommended in NUREG-0313, Reference 6, the flaw length is projected by increasing the original aspect ratio, lla. by the factor that the depth has increased to calculate the projected aspect ratio. The flaw length for the flaw is projected below.

The fatigue crack growth is calculated using the previously calculated thermal transient stress, the residual stress and the combined pressure, weight and thermal stresses. The range sets defined for this evaluation include 5 startup and shutdown events with 1 idle loop restart event occurring during each startup and shutdown cycle. The fatigue crack growth was calculated using the PC-CRACK program, Reference 8, and the fatigue crack growth rate specified in Appendix C of Reference 1. The fatigue crack growth was based a 3600 circumferential flaw model with two initial crack depths. The projected end of evaluation period flaw depth l

rounded up to 0.602" and the current flaw depth of 0.252" to establish the bounding fatigue crack growth condition. These calculations are documented in Attachment D.

l A review of these evaluations shows that the fatigue crack growth for both initial flaw depths is insignificant and therefore does not contribute to the final end of evaluation period flaw size.

From Table !WB-36415 the acceptable att ratio for a flaw length equal to or greater than 50% of the circumference and an applied stress ratio of 0.60 or less is 0.49, therefore the acceptable flaw depth, a, for the normal / upset conditions is ne a nc := 0.49 t n a nc = 0.632 *in which is greater than the projected end of evaluation period flaw depth of a jf = 0.602 in Applied Stress Ratio in SAWS for the Emergency / Faulted Condition per Table IWB-3641-6:

SR g = 0.473 Sm The smallest stress ratio given Table IWB-3641-6 is 1.2 which is significantly greater than the applied stress ratio of 0.473, therefore application of the IWB-3641-6 table would significantly underestimate the acceptable flaw depth, ag or the emergency / faulted condition.

f To demonstrate that the acceptable flaw depth for the emergency / faulted condition is greater than a for the nc normal / upset condition, the methodology provided Appendix C of Reference 1 is used to define the appropriate safety factor and Z factor for flaws in SAWS.
