Description:

The purpose of this calculation is to evaluate the results of General Electric's (GE) inspection of the CNS Core Shroud horizontal welds to determine if additional evaluation or NDE characterization is needed for the welds.

The inspection results will be evaluated using the " Evaluation and Screening Criteria for the Cooper Shroud

• developed by GE (see Attachment 2.4). Eight horizontal (circumferential) welds (H1, H2, H3, H4, H5, H6a, H6b, and H7) were inspected during CNS's 1995 refueling outage and are subject to this evaluation.

4.0 CALCULATION INPUTS 4.1 GE inspection data (see Attachment 2.3) 4.2 Core Shroud thickness (t) = 1.5 inches (see Attachment 2.4) 4.3 Crack growth extension (aa) = 0.6 inches for an 18 month fuel cycle (see.4). For the calculations in Attachments 2.1 and 2.2, a = aa.

4.4 Allowable flaw lengths are specified in Attachment 2 4.

5.0 ASSUMPTIONS 5.1 All uninspected areas of a weld are conservatively assumed to be through-wall cracks for the entire uninspected length of the weld (e.g., for weld H1 the flaw length between 0 - 15.5" = 15.5" x 1.65"/* = 25.58").

5.2 See sheet 7 of Attachment 2.4.

6.0 METHODOLOGY l

6.1 General ne General Electric screening criteria document (Attachment 2.4) specifies two i

methods for determining if additional evaluation or NDE characterization is needed for the Core Shroud welds: 1) Limit Load Analysis and 2) Linear Elastic Fracture Mechanics (LEFM).

6.2 Limit Load Method Inspection data is evaluated by calculating etYective flaw lengths using established

" proximity rule" equations and comparing these calculated flaw lengths with allowable flaw lengths. He allowable flaw lengths are for any 90' sector of the applicable weld. He application of the limit load effective length criteria is applied to two adjacent indications / flaws at a time. This methodology is explained in detail in Attachment 2.4.

6.3 LEFM Method Inspection data is evaluated by calculating equivalent flaw lengths using established " proximity rule" equations and comparing these calculated flaw lengths with the allowable flaw length. He allowable flaw length is compared I

to the maximum sinale equivalent flaw length. The allowable flaw length was determined as described on sheet 25 of Attachment 2.4. The equivalent flaw length is described on sheets 18-19 of Attachment 2.4.

J l

7.0 CALCULATIONS 7.1 Limit Load All eight horizontal welds were evaluated using the Limit Load screening criteria (reference section 5.0 of Attachment 2.4). The evaluation of welds H1, H2, H3, H4, H5, H6a, H6b, and H7 is included as Attachment 2.1.

7.2 LF.hi Three horizontal welds were evaluated using the LEFM screening criteria (reference section 5.0 of Attachment 2.4). He evaluation of welds H4, H5, and H6a is included as Attachment 2.2.

j

8.0 CONCLUSION

S All ualuated welds meet the applicable Limit Load and/or LEFM screening criteria. No fiather evaluation or NDE characterization is necessary for any of the horizontal welds.

Preface Introduction l

During October and November of 1995, GE Nuclear Energy inspection Serv 6ces performed Shroud support weld UT examinations at Nebraska Public Power District's Cooper Nuclear Station site. The original scope of examinations scheduled were all of the areas accessible for scanning with the GE Shroud OD Tracker Scanner on shroud support horizontal welds H1, H2, H3, H4, H5, H6A, H68 and H7. After examination of each weld, Nebraska Public Power District was notified of any indications within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of final sizing and categorization, depending on relevancy. In the events of actual cracking, ultrasonic length and depth sizing were provided.

Visual indications and examinations are documented under a separate IWI Report for the in-vesselVisualInspections.

l All accessible areas of the eight welds referenced rbove were inspected ultrasonically with the GE OD Tracker System. Actual circumferential scae areas obtained varied depending on accessibility due to various obstructions that were enccuntered. These areas ofinaccessibility j

are documented on the Smart 2000 examination data sheets provided within this report.

Descriptions of circumferential coverage and limitations are also described in the Examination Summary Sheet provided with each weld examination package.

1 Examination results are documented by weld number, in stand alone sections, within this Shroud j

UT report. Each section covers the weld number referenced (e.g. H1, H2, etc.) and provides a summary of examination, ultrasonic data examination sheets indicating type of indications

)

recorded, examination profiles illustrating ultrasonic coverage, documentation supporting any relevant findings, such as cracking, is well documented in the form of graphs, illustrations or charts displaying lengths and depths, and tables containing all critical information. The overall results of the scope of examinations can be found under the Examination Data section of this report and in table form, shown at the end of this preface section.

Procedure The shroud was examined per " Procedure for Automated Ultrasonic Examination of Shroud Assembly Welds", UT-CNS-503V4, Revision O. Woric was performed per Nebraska Public Power District's work authorizations and in acenrdance with the GENE QA Manual QAM-003. Shroud inspectibility was pre-determined from the Nebraska Public Power District Shroud OD Inspectibility Study Report and is not referenced within this document. By utilizing this procedure a pre-inspection of the projected scan areas were documented in order to ensure that proper clearances were available for the shroud UT inspection tooling.

Equipment The equipment utilized for the Shroud UT Examinations was the Smart 2000 Data Acquisition System, the GE Shroud OD Tracker Scanner, the GE Motion Controller and Tri-modal search units containing a combination of 45' Shear Wave,60* Refracted Longitudinal, and OD Creeping Wave search units. Installation and use of this equipment is described in detailin the Procedures section of this Report. Related equipment requiring certifications can be found in the Certifications section of this report.

Due to varying obstacles near the shroud outside diameter, and in close proximity to the welds that were examined, interferences in scanning were encountered. The Guide Rods, Com Spray j

Downcomers and Jet Pump Sensing Lines all posed scanning limitations at various locations of the welds. In addition to these limitations, the combination of welds with unfavorable geometric configurations did further contribute to loss of examination coverage. Every attempt was made to i

obtain the most extensive examination coverage possible.

Data Recordina l

All scan data has been digitized and recorded by the Smart 2000 Data Acquisition System onto 1 Gipabyte optical discs. The original data discs are to be provided to Nebraska Public Power Distrh:1 and are included as part of the Shroud Ultrasonic Examination Report, October /

November 1995 - 1F5CN.

The flaw indications recorded were sized in circumferential length and thru-wall depth. A measurement of flaw maximum extension from the initiating surface, whether ID or OD, is supplied in actual crack height and length, as recorded. A maximum flaw depth reading, along with it's corresponding circumferential position, was taken for each indication. Indications are referenced by Indication Number, for future reference. Start and stop positions of each indication are also supplied by their respective indication reference number for future comparison.

Summary The following table summarizes the inspections performed and overall findings of the examinations. Detailed information of the examinations can be found in the Examination Data section of this report.

The parameters for these indicatens are on the following page.

The 45* shear wave recorded inside and outside surface weld crown geometry and non-relevant indications along with the indicatens referenced.

The 60* RL recorded inside surface weld crown geometry and norwelevant indicatens along with the endcations refererced.

The OD creeping wave recorded non-relevant indicetsons and inside surface geometry along with the indications referenced.

Cucumferential(L) dimensens were recorded in angular units. The conversion factor for linear units is 1.65 inches per degree.

This exarranaten was performed only from the plate side due to the shroud lug interferences which obstruct scanning on the shroud support flange side. This examination was also performed simulta.W with the H2 weld.

This exam was limited to the areas scanned due to obstructons from the guade pins, core spray downcomets, shroud kfbng lugs and instrumentation lines.

l The examinaten area that was interrogated by all angles was 240.90* (63.9%).119.10* (33.1%) was not examined due to the above referenced obstructons l

The 45' shear wave recorded inside and outside surface weld crown geometry and non-relevant indcations.

The 60* RL recorded inside surface weld crown geometry and non-relevant indcations.

The OD creeping wave recorded non-relevant indcations and inside surface geometry.

Circumferentral(L) dimensions were recorded in angular units. The converson factor for linear units is 1.65 inches per degree.

This examination was performed only from the plate side due to the narrow width of the top guide support nng. This examination was also performed simultaneously with H1 weld.

This exam was limited to the areas scanned due te oostructions from the guide pins, core spray downcomers, shroud liftsng lugs and instrumentaon lines.

The examination area that was interrogated by oli angles was 240.90* (66.9%).119.10* (33.1%) was not examined due to the above referenced obstructiona.

Tis parameters for these indcations are on the following page.

The 45' shear wave recorded inside and outside surface weld crown geometry and non-relevant indcations along with the indcatons referenced.

The 60* RL recorded inside surface weld crown geometry and non-relevant indicatens along with the indications referenced.

The OD creeping wave recorded norgelevant indicatens and inside surface geometry along with the indcations referenced.

Circumferential(L) dimensions were recorded in angular units. The conversion factor for linear unds is 1.55 inches per degree.

This examination was performed from the plate side only due to the configuration of the top guide support ring.

This exam was limited to the areas scanned due to obstruchons from the guide pins, core spray downcorners, and shroud lifting lugs.

The exarnination area that was interrogated by all angles was 287.55' (79.9%). 72.45* (20.1%) was not examined due to the above referenced obstructions

The 45* shear wave recorded inside and outside surface weld crown geonstry, weld discontinuttles and non-relevant indications.

The 60* RL recorded inside surface weld crown geometry, weld discontinuities and non-relevant indications.

lhe CD creeping wave recorded non-relevant indicatens, weld discontinuities and inside surface geometry.

Circumferential (L) dimensens were recorded in angular units. The converson factor for linear units is 1.55 irches per degree.

This examination was performed from both sides of the weld.

This exam was limited to the areas scarned due to obstructions from the guide pins, core spray downcomers, shroud lifting lugs and instrumentation

!!nes.

The examination area that was interrogated by all angles was 282.40* (78.5%). 77.6* (21.5%) was not examined due to the above referenced obstructons.

During the examination of the referenced weld, one (1)indicaten associated with IGSCC/lASCC were recorded by the Smart 2000 system utilizing a TRI-MODAL search unit containing a 45* shear wave, OD creeping wave and 60* refracted longitudinal (RL) wave.

The parameters for this 6ndcation are on the following page.

The 45* shear wave recorded inside and outside surface weld crown geometry and norwelevant indications.

The 60* RL recorded inside surface weld crown geometry and non-relevant indications along with the refererenced indcation.

The OD creeping wave recorded non-relevant indications and inside surface geometry along with the referenced indicaton.

Circumferential (L) dirnensons were recorded in angular units. The converson factor for linear units is 1.55 inctes per degree.

This examination was performed from teth sides of the weld.

This exam was limited to the areas scanned due to obstructens from the guide pins, core spray downcomers, shroud lifting tugs and instrumentaion lins.

The examination area that was interrogated by an angles was 273.90"(76.1%). 86.10"(23.9%) was not examined due to the above referenced obstructions.

The parameters for this indication are on the following page.

The 45* shear wave recorded inside and outside surface weld crown geometry and non-relevant indcations along with the referenced indcation.

The 60* RL recorded inside surface weld crown geometry and non-relevant indcations along with the referenced indicaten.

The OD creeping wave recorded non-relevant indcat.ons and insde surface geometry along with the referenced indcaten.

Circumferential(L) drnensiorr were recorded in angular units. The converson factor for linear units is 1.55 inches per degree.

This weld was examined from the plate side only, however additional scarnng was performed across the weld and and on the core plate nrig side, directed away from the weld, and resulting in no relevant indcations found. This was achieved because the examination was performed simutarW with the H68 weld.

f This exam was limited to the areas scanned due to obstructens from the guide pins, coru spray downcomers, shroud lifting lugs and instrumentation ines The examination area that was interrogated by au angles was 264.40* (73.4%). 96.850* (26.6%) was not examined due to the above referenced obstructions.

The parameters for these indications are on the following page.

i The 45* shear wave recorded inside and outside surface weld crown geometry and non-relevant indications.

The 60* RL recorded inside surface weld crown geometry and non-relevant indications.

The OD creeping wave recorded non-relevant indications and inside surface geometry.

Circumferer.tial (L) dimensions were recorded in angular units. The conversion factor for linear units is 1.55 inches per degree.

l This weld was examined from the plate side only, however additonal scanning was performed across the weld and and on the core plate nng side,darected away from the weld, and resulting in no relevant indications found. Also the looking down transducer from the H6A examination achieved a limited scan wth the transducer directed toward the weld, also resulting in no relevant indications found. This was acheived because the

]

examination was performed simutaneously with the H6A weld.

This exam was limited to the areas scanned due to obstructons from the guide pins, core spray downcomers, shroud lifting lugs and instrumentation lines.

The examination area that was interrogated by all angles was 264.40* (73.4%). 95.60* (26.6%) was not examined due to the above referenced obstruebons.

The 45* shear wave recorded inside and outside surface weld crown geometry and non-relevant indicatnons.

The 60* RL recorded inside surface weld crown geometry and norwelevant indications.

The OD creeping wave recorded non-relevant indicatens and inside surface geometry.

Circumferential (L) dimensions were recorded in anguar units. The conversion factor for linear units is 1.49 inches per degree This examinaten was performed from the plate side only due to the weld configuration of the lower plate support and the backing nng config This exam was hmited to the areas scanned due to obstructens from the guide pens, core spray downcomers, shroud lifhng lugs, instrumentation lines.

The examinabon area that was interrogated by all angles was 246.90* (68.6%).113.10'(31.4%) was not examined due to the above referenced obstructons.

1.0 INTRODUCTION

SHEET 5

y 40 In preparation for the Cooper shroud inspection, Nebraska Public Power District has requested GE to develop screening criteria for indications that may be found at the shroud -

l welds.- Recently, indications have been discovered in some BWR shrouds as a result ofin-

+

vessel visual inspection (IVVI). When indications are found by IVVI, only the lengths of I

the indications are known. Given that non-destructive examination (NDE) of every visually detected indication would be difficult and time con = ming. a method of screening indications for subsequent evaluation is required. This report presents such a screening criterion.

The guiding parameter used for the selection of the indications for further evaluation is the allowable through-wall flaw size, which already includes safety factors. If all of the visually detected indications are -> mad to be through-wall, then the longest flaws, or combination of flaws, would have the limiting margin against the allowable through-wall flaw size. In reality, the indications are likely not through-wall, and therefore the criteria and methods presented in this report are conservative.

f The result of this procedure will be the determination of the effective flaw lengths for the 4

limit load criteria and equivalent flaw lengths for the linear clastic fracture F+tdes j

(LEFM) criteria. These flaw lengths will be used to compare against the allowable flaw size and select indications for more detailed evaluation.

l The determination oflimit load effective flaw length is based on ASME Code,Section XI,

]

Subarticle IWA-3300 (1989 Edition) proximity criteria. These criteria provide the basis e

for the combination ofneighboring indications depending on various geometric dimensions. The proximity rules described here also conservatively assume that there is interaction between two perpendicular flaws. It is assumed that circumferential and axial indications could increase the limit load effective flaw length depending on the unflawed distance between them. This limit load effective circumferential flaw length must be compared against the allowable cirwmb dal flaw length. The limit load effective axial flaw length would be compared against the allowable axial flaw length. Crack growth over a subsequent cycle is included in the limit load effective flaw length determination.

j adjacent flaw tips on the stress intensity factor. These criteria provide the basis for the summation ofindividual flaws. Crack growth over a subsequent cycle is also included in the LEFM equivalent flaw length determination.

i l

Uncertainty in sizing can also be incorporated into the screening criteria. This is done by adding the uncertainty on crack length sizing to the crack growth expected over the next '

l cycle. However, the several significant conservatisms introduced in the methodology are

{

considered to compensate for uncertainty in sizing.

I l

Flaws are considered in the same plane if the perpendicular distance between the planes is

3.0 inches (twice the shroud thickness of 1.5") or less. Any flaws which lie at an angle to the horizontal plane should be separated into a circumferential and axial component.

These components can then be used separately in the determination oflimit load effective flaw lengths and LEFM equivalent flaw lengths.

l The selection ofindications for further investigation can be performed by evaluating the resulting limit load effective flaw lengths or LEFM equivalent flaw lengths. Indications with flaw lengths greater than the allowable flaw sizes would require further characterization by NDE or more detailed analysis. The procedure described here is i

conservative, since d of the indications are assumed through-wall and are being compared against the dowable through-wd flaw size.

This report describes the following steps:

'M E I SHEET O

y 4-0

- The limit load effective flaw lengths are based on ASME Code,Section XI proximity criteria as presented in Subanicle IWA-3300. The procedure addresses both circumferential and axial flaws. Indications are considered to be in the same plane if the -

perpendicular distance between the planes is less than 3.0 inches. All flaws are considered to be through-wall. Therefore, indications on the inside and outside surface should be treated as if they are on the same surface. When two indications are close to each other, rules are established to combine them based on proximity. These rules apply only to the limit load evaluation. The crack tip interaction criteria for LEFM are described in Section 3.2.

Flaw length inspection uncertainty can be incorporated in the proximity rules by adding the uncertainty to crack growth, e.g., replace Aa by (Aa + U) or 2Aa by (2Aa + 2U).

2.1 Proximity Rules The flaw combination methodology used here is simihr to the ASME Code,Section XI rwduJiy rules concerning neighboring indications. Under the rules, if two surface j

indications are in the same plane (perpendicular distance between flaw planes < 3.0 inches) and are within two times the depth of the de indication, then the two indications must be considered as oneindication.

In Figure 2-1, two adjacent flaws L1 and L2 are separated by a ligament S. Crack growth would cause the tips to be closer. Assuming a conservative crack growth rate of 5x10-5 n/hr and 8000 hours0.0926 days <br />2.222 hours <br />0.0132 weeks <br />0.00304 months <br /> ofhot operation, the crack extension, Aa, at each tip is 0.6 i

inches for an 18 month fuel cycle (12,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />), and 0.8 inches for a 24 month fuel cycle (16,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />). Therefore, combining the crack growth and proximity criteria, the flaws are emmad to be close enough to be considered as one continuous flaw if the ligament is less than (2 x Aa + 2 x shroud thickness). For a shroud thickness of 1.5 inches, this bounding ligament is 4.2 inches for an 18 month fuel cycle and 4.6 inches for a 24 month fuel cycle. Thus, if the ligament is less than 2Aa + 2t, the effective length is (L1 + L2 + S + 2Aa). Note that the addition of 2Aa is to include crack growth at the 1

other (non-adjacent) end of each flaw (See Figure 2-2).

l GENacinar Emray GENE 5231741293

{

Rninien 2 NEDC 92,:l;?s11gn 2.4. l If the ligament is greater than 2Aa + 2t, then the limit load effective flaw length is determined by adding the projected tip growth to each end of the flaw. For this exak Ed Lleg= L1 + 2Aa, and L2 g= L2 + 2Aa.

e A similar approach is used to combine flaws when a circumferential flaw is close to an axial flaw (See Figure 2-3). If the ligament between the flaws is less than Aa + 2t, then the limit load effective flaw length for the circumferential flaw is L g= L1 + S + Aa (the e

Wading ligament for these cases). If the ligament is greater than Aa + 2t, then the flaws are treated separately.

After the circumferential and axial flaws have been combined per the above criteria, a map of the limit load effective flaws in the shroud can be made, and the effective flaw length can be used for subsequent analysis.

i To demonstrate the proximity criteria, three examples are shown in Table 2-1 and described below.

2.1.1 Case A CircumferentialFlaw-No AxialFlaw This case applies when two circumferential indications are considered. Figure 2-2a shows this condition. If the distance between the two surface flaw tips is less than 2Aa + 2t, the indications must be combined such that the limit load effective length is (See Figure 2-2b):

This case applies when both a circumferential and an axial flaw are being considered.

2 Figure 2-3a demonstrates this condition. For this case, only growth of the circumferential flaw is considered. If the distance between the circumferential indication tip and the axial indication is less than Aa + 2t, then the effective circumferential flaw length is (See Figure 2-3b):

where: L2 = length ofaxialindication j

If the distance between the circumferential indication tip and the axial indication is greater than Aa + 2t, then the flaws are not combined (See Figure 2-3c) and the effective lengths are:

L1egr= L1 + 2Aa (for circumferential flaw)

L2 gr= L2 + 2Aa (for axial flaw) e 6

2.2 Application of Limit Load Effective Flaw Length Criteria J

l The application of the limit load effective length criteria is applied to two adjacent indications at a time. Figure 2-4 is a schematic which illustrates the process. For f

example, using the O' azimuth as the starting location for a circumferential weld or plane, the general procedure would be as follows:

l Moving in the positive azimuthal direction, the first indication encountered is l

indication 1.

l t

The next indication is indication 2.

. Apply proximity rules to the pair ofindications (' dications I and 2). Combine the l

m flaws if necessary (L1 + L2 + S + 2Aa). If the flaws are comb *med, the r=*ing flaw becomes indication 2.

l

. Cantinne along positive adamthat direction until the next imlicatian is

.ncomtera. This secomes indication 3.

.- Apply ywaindiy rules to indications 2 and 3. Ifimlication 2 is a combined flaw, do j

not add an additional Aa, since it is included in the limit load effective flaw length previously determined.

C4= proximity rule evaluation until all indications along the subject weld or i

plane have been considered.

W MCH 24 3.0 STRUCTURAL ANALYSIS SHEET llo or 4 0 The preceding section of this report described the determiration oflimit load effective flaw lengths from the IVVI results. These limit load effective flaw lengths have to be compared to the allowable flaw lengths to assess the structural integrity of the shroud.

This section describes the details and the results of the structural analysis performed to determine the allowable flaw lengths. The structural analysis consists of two steps: (1) the determination of axial and circumferential stress magnitudes in the shroud, and (2) the calculation of the allowable flaw lengths. Both the fracture mechanics and limit load methods are used in the calculation of allowable flaw lengths 3.1 Applied Loads and Calculated Stresses The applied loads on the shroud consist of differential pressure and dynamic (seismic).

'Ihe dynamic loads consist of a horizontal shear force and an overturning bending moment.

The shear force acts in a direction which does not influence crack growth significantly, so it is not considered. The bending moment stress at a shroud cross-section varies as a fonction ofits vertical distance from the top of the shroud. Pressure on the crack face is not considered for two reasons: (1) It is overly conservative to consider the stress on a postulated through-wall flaw when the flaw is unlikely to be through-wall, and (2) the pressure stress on the crack face is negligible. Because of the inherent ductility of the material (which will be dim =1 in Section 3.2 of this report), residual stresses and other secondary stresses do not arTect structural margin. Thus, they need not be considered in the analysis.

The magnitudes of the applied loads were obtained from the dynamic stress analysis (Reference 3-1) and system infonnation report (Reference 3-2). The nominal shroud

~

radius and thickness (Reference 3-3) were used to calculate the stresses from the applied loads. Stresses are calculated based on strength of materials formulas. Figure 3-1 shows j

the weld designation and relative locations in the shroud. Table 3-1 shows the calculated j

dynamic bending stress magnitudes for both the upset and faulted conditions. The appropriate pressure differences for the normal / upset and faulted conditions are shown in Table 3-2.

Both the limit load and the LEFM methods were used in determining the allowable flaw sizes in the ahroud. Since the limit load is concerned with the gross failure of the section, the allowable flaw length based on this approach may be used for comparison with the sum of the limit load effective flaw lengths, determined in Section 2.2, of all the flaws at a cross-section. On the other hand, the IHM approach considers the flaw tip fracture toughness and thus, the allowable flaw length based on this approach may be used for comparison with the LEFM equivalent flaw length, determined in Section 3.2.2, at a cross-section. The fluence levels at welds H1, H2, H6B, and H7 are such that no significant embrittlement effects are expected.

Therefore, only the limit load approach was dsed at these welds. The technical approach for the two methods is desented next.

SHEEL IE y 4-0 The shroud material (austenitic stainless steel) is inherently ductile and it can be argued that the structural integrity analysis can be performed entirely on the basis oflimit load. In fact, J-R curve measurements (Figure 3-2) made on a core shroud sample taken fmm an overseas plant having higher fluence (8x1020 n/cm2) than Cooper showed stable crack extension and ductile failure. The ASME Code recognizes this fact in using only limit load techniques in Section XI, Subsubarticle IWB-3640 analysis. Nevertheless, a conservative fracture mechanics evaluation was performed using an equivalent K cI cowege=&gto the materialJ c-I 3.2.1 Determination ofKIc The KIc for the overseas plant shroud was approximately 150ksi8n'. Use of this equivalence is extremely conservative since:

i) The actual fluence for Cooper is lower than that for the overseas plant from which J-R curves were obtained.

ii) The J-R curves showImax values well above the J c, confonig that there is load I

capability well beyond crack initiation (See Figure 3-2).

Also, for cLuAmnial flaws K c is divided by ASME Code safety factors: 2.8 for I

normal and upset condition stresses, and 1.4 for faulted condition stresses. K c is divided j

I by 3.0 and 1.5 respectively for axial flaws. For the analysis presented here, the LEFM analysis is confined to welds H4 to H6A. The fluence corresponding to welds at and below the core plate and above the top guide is an order ofma,JEide lower and the

- M +ad fracture toughness is comparable to that ofthe unirradiated material.

Therefore, for those locations only the limit load analysis is used.

3.2.2 LEFM Equivalent Flaw Length A consideration that applies only to the fracture machanics analysis is the question, "When is a flaw independent of an adjacent flaw?" The ASME Code proximity rule described in Section 2 considers how flaws can link up and become a single flaw as a result of proximity. However, even when two flaws are separated by a ligament that exceeds 2Aa +

2t, they may not be considered totally indapaadent ofeach other. That is, the flaw tip stress intensity factor may be affected by the presence of the adjacent flaw. This can be 1

14

~

l GENueiner Emrgy GENE-523-174133 Aridsses 2 i

accounted for by using the finite width correction factor for a flaw in a finite plate. For a through-wall flaw in an " infinite" plate, the stress intensity factor is:

g qg.;hTMCH 24-K = oJ(na)

SEET M

' W 12.

For a finite plate, the K value is higher as determined by the finite width correction f

factor, F (Reference 3-4). In this screening evaluation it is assumed that the plate is i

" infinite" if the correction factor F is less than 1.1.

As with the limit load proximity criteria, indications are considered to be in the same plane if the perpandimi-distance between the planes is less than 3.0 inches. All flaws are j

considered to be through-wall. Therefore, indications on the inside and outside surface l

shouk' be treated as if they are on the same surface. When two indications are close to each other, rules are established to combine them based on proximity of adjacent crack tips. These rules are described here and apply only to the LEFM evaluation. The proximity criteria for limit load are desenbed in Section 2.0. Uncertainty in sizing may be incorporated into the LEFM flaw length by adding the ures. 4y to each end of the flaw.

Thus, An in the next paragraph di==== ton is changed to (As + U).

As seen in Figure 3-3, if the width of the plate exceeds 2.5(L1 + 2Aa) (or a/b less than i

0.4), then there would be no interaction due to plate end edge effects. If this same condition is applied to two neighboring flaws, then there will be no interaction between the two indications if the tips are at least 0.75(L1 + L2 + 4Aa) apart. Thus, if the distance between indications is greater than 0.75(L1 + L2 + 4Aa), then Aey may be considered as I

two separate flaws. Ifhowever, they are closer, the LEFM equivalent flaw length is the sum of the two individual flaws including crack growth.

3.3 Limit Load Analysis A through-wall circumferential flaw was assumed in this calculation. Limit load

calculations were conducted using the approach outlined in Subsubarticle IWB-3640 and Appendix C of Section XI of the ASME Code. The flow stress was taken as 3Sm. 'Ihe Sm value for the shroud material (Type 304 stainless steel) is 16.9 kai at the approximate normal operating temperature of 550'F.

3.4 Shroud Thickness Considerations A shroud thickness of 1.5 inches was used in developing the screening criteria. However, there are locations in the shroud with wall thickness greater than 1.5 inches. Therefore, it must be determined if the use of 1.5 inches is applicable to all other shroud locations.

The screening criteria based on the 1.5 inches thickness is considered applicable to locations ofgreater thickness, since stresses were determined based on the 1.5 inch thickness. This results in conservative stress values when applied to locations with thickness greater than 1.5 inches, such as the weld between the 1.5 inch shroud cylinder and 3 inch top guide support ring.

GENE-523-174.W3 Rahien 2 4.0 ALLOWABLE THROUGH-WALL FLAWS E M m 2.6 SHEET 25 0F 40 Allowable through-wall flaw sizes were determined using both fracture mechanics and limit load techniques for both circumferential and axial flaws. It should be emphasized that the allowable through-wall flaws are based on many conservative assumptions and are intended for use only in the screening criteria. More detailed analysis can be performed to justify larger flaws (both through-wall or part-through when measured flaw depths are available). However, since the intent of the screening criteria is to determine when additional evaluation or NDE characterization is needed, a conservative bounding approach is utilized.

4.1 Allowable Through-Wall Circumferential Flaw Size Both the LEFM and limit load methods were used to evaluate the allowable through-wall flaws. At welds H4 to H6A, LEFM and limit load analysis methods were used, and the limiting locations for through-wall cracking occurred at the H6A weld. For the limit load analysis, the governing case is the H7 weld location where the pressure and dynamic stresses are high.

.4.1.1 LEFM Analysis The total axial stress at weld H6A is 1.34 kai for the upset condition and 2.91 kai for the faulted condition. Using the ASME Code safety factors for fracture analysis (2.8 for normal and upset and 1.4 for faulted), the faulted condition is limiting.

To determine the allowable flaw size based on LEFM mathmia, the conservatively estimated irradiated material fracture toughness K cI value of150 kaid was used.

Applying the ASME Code safety factors, allowable K values of ~ 54 ksid (upset) and I

~ 107ksid (faulted) were obtained. The allowable flaw size was calculated using the following equation:

)

Kr = G.c](na) where G is a curvature correction factor as defined in (Reference 4-1), a is the total m

axial stress, and 'a'is the half flaw length. Th' bending correction factor G is neglected e

5 4

because of the ductility of the material. The allowable through-wall circumferential flaw length (2a) was determined as = 145 inches for H6A.

neuen 2 4.2 Allowable Axial Flaw Size SHEET 27 0F 40 4.2.1 LEFM Analysis The allowable axial flaw size is governed entirely by the pressure hoop stress. As with the circumferential flaw case, the allowable axial flaw size was determined assuming a through-wall flaw. For a through-wall flaw oflength 2a in the shroud, the applied stress intensity factoris given by:

K = M *a6 *M where M is the curvature correction factor given by-M = [1 + 1.61a2/(Rt)]o.5 (from Reference 4-2)

In the above expression, the allowable flaw length 2a can be detennined by equating the calculated K to the fracture toughness of150 ksiM. The hoop stress for the faulted condition is 1.79 ksi; the ASME safety factor of1.5 is applied and the result is used in the previous equation.

The allowable flaw length was conservatively determined to be 2a = 85 inches above the core plate.

4.2.2 Ilmit Load An alternate approach to determining the allowable flaw size is to use limit load techniques. The allowable flaw length is given by the equation:

/

oh" of (M

• SF) where M is a rcrvature correction factor as defined above, ar= 3 Sm is the flow stress, SF is the safety factor (3.0 for upset conditions,1.5 for faulted), and ch = the hoop stress corresponding to the AP of 30.3 psi (faulted) above the core plate and 31.21 psi (upset) below the core plate. The allowable flaw length based on the limit load analysis is 330 inches above the core plate (using the limitino shroud diameter at welds H1 and H2) and 167 inches below the core plate. Since the value above the core plate exceeds the LEFM value, the allowable axial through-wall flaw length is 85 inches between H3 and H6A.

GENuctee Enagy GENE.3211N 129s Asidsden 2 NMNm M 5.0 SCREENING CRITERIA SNRT ?A E 40 The determination of the allowable through-wall flaws has been described in Section 4.

The objective was to use the allowable flaw size as the basis for the screening criteria.

Since the screening rules represent the first step in the evaluation, they are by definition conservative. If the criteria are exceeded, the option of doing further detailed evaluation or performing additional NDE remains. The allowable through-wall flaws were:

C CircumferentialFlaws

- H1:

423 inches (limitload)

- H2:

420 inches (limitload)

- H3:

393 inches (limitload)

- H4:

386 inches (limit load), 235 inches (LEFM)

- H5:

368 inches (limit load),168 inches (LEFM)

-H1-H2:

330 inches (limitload)

-H3-H6A: 85 inches (LEFM)

- H6B-H7: 167 inches (limitload)

A conservative approach in developing the screening mie is to include both the LEFM and limit load analysis. For circumferential flaws, LEFM provides the limit on LEFM 0

equivalent single flaw length for H4 through H6A, while the limit load analysis provides the limit on effective camulative flaw length. For axial flaws, the allowable flaw length is 330 inches between H1 and H2, 85 inches between H3 and H6A (LEFM), and 167 inches below the core plate (limit load).

For circumferential flaws at welds H4 through H6A, the limits are applied as follows. The fracture mechanics based limit for a single equivalent flaw length at H6A (for example), as determined in Section 3.2.2, is 145 inches. This in itselfis not sufficknt, since there could be several flaws (each less than 145 inches) in's circumferential riane that cumulatively add up to greater than 360 inches (the allowable circumferential flaw size based on limit

load analysis). Thus, the sum of the effective flaw lengths, as determined in Section 2.2, i

should be less than 360 inches.

While this fully assures the ASME Code margins, an additional conservative assumption is included in the screening. This states that the sum of the limit load effective flaw i

lengths cannot be more than 360/4 = 90 inches in any 90 degree sector of the shrond.

This is a conservative restriction that assures that long continuous flaws are not j

admissible.

i The approach used here for the 90 inch limit for circumferential flaws is to assume a template with a moving window equal to a 90* sector. The sum of the limit load effective flaw lengths that appear in the window should be less than 90 inches. This is shown graphically in Figure 5-1. A similar restriction based on limit loads is not needed for axial flaws, since field experience has shown that they are typically =Wa*ad only with circumferential welds and are unlikely to be aligned in the same plane.

The allowable flaw length of 90 inches for any 90 degree sector applies to weld H6A.

Similarly, limit load allowable flaw lengths divided by four apply to welds H1 through H7.

When considering LEFM based evaluations, the crack interaction criteria described in Section 3.2 must be applied in comparing against the allowable lengths. For example, for

=j= =st flaws where the spacing, S,' is less than 0.75 (L1 + L2 + 4Aa), the length

- L = L1' + L2'is used for comparison with the LEFM based allowable flaw length. The lengths L1' and L2' are as determined in Figure 3-3.

The criteria presented in this report are conservative in that continuous flaws (for limit load) were assumed. Additional analysis assuming the flaws are non-continuous (that is, distributed around the circumference of the shroud) or part-through wall will yield larger cumulative flawlengths.

SUMMARY

.0F SCREENING CRITERIA SHEET 32 g 4o 4

The screening criteria are schematically shown in Figure 6-1. The first step is to map the flaw indications observed by IVVL Next the proximity rules are applied to the flaw map to develop limit load effective flaw lengths. The results of the limit load effective flaw

- l lengths are also mapped.

q For axial flaws, two neighboring flaws must be summed if S < 0.75(LI + L2 + 4Aa). If the longest resulting flaw is less than 85 inches, then the screening limit is met for axial flaws.

For circumferential flaws, all limit load effective flaw lengths (as determined by the methods outlined in Section 2.0) are summed in any 90' sector using a template. The next step is to compare the longest LEFM equivalent flaw to the LEFM based screening criteria for welds H4 to H6.L g

2. 4-7.0 COOPER FIELD HISTORY gag 34 0F 40 4

Based on current available information at GE, the Cooper field history was tabulated.

Table 7-1 contains the list of known cracking incidences at Cooper. The relatively short list of cracking incidences is likely a reflection of the Cooper water chemistry quality.

A.1 Water Chemistry i

l For the first two cycles of hot operation, Cooper operated with relatively high primary l

water conductivity. As can be seen in Table 1, the cyclic conductivity mean values j

averaged 0.27 pS/cm. There was a dramatic condu.,dvity improvement during the third

[

cycle where the conductivity decreased to 0.142 pS/cm. Since the third cycle,.

conductivity values have improved and were excellent at approximately 0.10 pS/cm during the last three operating cycles. Although Cooper is characterized by some of the best j

water chemistry in the BWR fleet (noting that Cycle 16 conductivity is somewhat higher),

)

1 there were several documented early water a==4y transients experienced at l

Cooper (1):

)

i

1. August 29,1974 - Cooper reactor water conductivity reached 5 pS/cm and pH decreased to 5.5 during shutdown due to a condensate demineralizer resin j

\\

l intrusion (Cycle 1).

i

2. December 8,1974 - Cooper reactor water conductivity reached 10 pS/cm at power due to a condenser leak (Cycle 1).

3. January 27,1975 - Cooper reactor water conductivity reached 11.5 pS/cm and pH decreased to 4.8 at power due to a RWCU resin intrusion (Cycle 1).

4. July 2,1975 - Cooper reactor water conductivity reached 12 pS/cm at power due to a condenser tube leak (Cycle 1).

5. February 21,1976 - Cooper reactor water conductivity reached 4.3 pS/cm and pH decreased to 4.9 at power due to a PM resin intrusion. Chloride was also measured at 48 ppb (Cycle 1).

6. May 22,1976 - Cooper reactor water conductivity reached 4.9 pS/cm and pH decreased to 4.9 at power due to a suspected resin intrusion. Chloride was j

also measured at 50 ppb (Cycle 1).

7. February 25,1977 - Cooper reactor water conductivity reached 1.1 pS/cm and pH decreased to 5.6 at power due to a suspected resin intrusion. Chloride was also measured at 30 ppb (Cycle 2).

Because of the some higher early life conductivity and intrusion history, it is likely that intergranular stress corrosion cracking (IGSCC) initiation was accelerated in susceptible areas (both uncreviced and creviced) of the primary system, including the shroud. The effect of sulfate / conductivity on crack initiation in uncreviced material is presented in Figure 1. It is clear that an increase in sulfate / conductivity results in an acceleration in crack initiation as measured by the constant extension rate test (CERT). A similar type of initiation acceleration is expected for chloride ions.

The strong correlation between conductivity and IGSCC susceptibility in uncreviced sensitized stainless steels has also been av=i-i in various other laboratory studies (2-4) and it is evident that a significant decrease in crack initiation time is ar=+ed with increased concentrations of certain deleterious anionic impurities, in particular sulfates and chlorides. For creviced BWR components the strong correlation of SCC== aptibility with actual BWR plant water chemistry history has been documented (5).

A.2 Shroud Evaluation

'Ihe recent cracking of shrouds at several BWRs has placed this stress corrosion concern at the highest levels. When Cooper is compared to 51 other BWRs relative to possible shroud performance, the following rankings and factors are noted:

1. First 5 cycle mean conductivity (0.188 pS/cm)- 41/51 highest. Shrouds in BWRs with lower 5 cycle mean conductivity have cracked.

2. Total mean conductivity (0.152 pS/cm) - 42/51 highest (based on June 1994 data). Shrouds in BWRs with lower total mean conductivity have cracked.

3. On-line years (14.6) - 13/51 highest (based on November 1993 data).

Shrouds in BWRs with lower on-line years have cracked.

have cracked.

5. Shrouds fabricated out of Types 304L and 347 stainless steel and Cooper's shroud's material ofconstruction, Type 304 stainless steel, have cracked. It should be noted that all Type 304 stainless steel shrouds iaWad to date have revealed cracking.

l

6. Shrouds built by Rotterdam, Sun Ship, P. F. Avery and Cooper's shroud's

==anf=@lrer, Bingham Willamette, have cracked.

Based on the experience of shroud cracking in BWRs with relatively good water chamintry quality and at low fluence locations, independent of==anf=eleer, material of construction and relative age, future cracking in Cooper's shroud cannot be mied out.
