SECTION 1 INTRODUCTION i

^
, This flaw evaluation handbook has been designed for the evaluation of l
indications which may be discovered during insarvice inspection of the Zion, Byron, and Braidwood Unit 1 and Unit 2 reactor vessels. The tables and charts
] provided in the Appendix of this report allow the evaluation of any indication discovered in the regions listed below without further fracture mechanics
- calculations. The fracture analysis work has instead been done in advance, in accordance with the criteria of ASME Code Section XI, and is documented in a companion background and technical basis report (1). Use of the handbook will j allow the acceptability of such larger indications than would be allowable by
, only using the standards tables of Section XI (2). A schematic representation of the flaw evaluation process of Section XI Appendix A is provided in Figure i 1-1.
] The handbook is applicable to low alloy steel base metal and welds in the following locations in the Zion, Byron, and Braidwood Units 1 and 2 reactor vessels. The following regions are covered:
l i o Beltline (core region) [ Note that this region includes all the core '
regionwelds) o Inlet nozzle: nozzle to shell weld, safe end to nozzle weld and 3 innerradius(corner) o Outlet nozzle: hozzle to shall weld, safe end to nozzle weld, and innerradius(corner) l o Lower head: ring to lower shall weld and ring to lower head weld o Top head ring to dome weld, and the head ring to flange weld ,
4 o Lower flange to shall weld.
The geometry of each of' these regions is chown in Figures 1-2 through 1-6, and l repeated at the appropriate section of the Appendix.

e The highlight of the handbook is the design of a series of flaw evaluation cha.-ts for both surface flaws and the embedded flaws. Since the characteristics of the.two types of flaws are different, the evaluation charts designed for each are distinctively different. The evaluations are organized according to the location in the vessel, as listed above, and for each location, charts are provided for both surface and embedded flaws along with worked examples as necessary.
The flaw evaluation charts were designed based on the Section XI code criteria of acceptance for continued service without repair as contained in paragraph IWB-3600. Through use of the charts, a flaw can be evaluated by the code analytical criteria instantaneously, and no follow-up hand calculation is
, required. Most important of all, no fracture sechanics knowledge it needed by
^
the user.
TheflawevaluationchartsareprovidedinAppendixAofthisdocilment,and have been developed using the methodology discussed in the technical basis document (1). For flaw evaluation of an indication discovered in an inspection, turn directly to the Appendix.
1.1 CODE ACCEPTANCE CRITERIA There are two alternate sets of flaw acceptance criteria for continued service without repair in paragraph IWB-3600 of ASNE Code Section XI. Namely,
- 1. AcceptanceCriteriaBasedonFlawSize(IWB-3611)
- 2. Acceptance Criteria Based on Stress Intensity Factor (IWB-3612)
Both criteria are comparable in accuracy for thick sections, and the acceptance criteria (2) have been assessed by past experience to be less ,
restrictive for thin sections, and for outside surface flau in many cares.
In all cases in this handbook, the more beneficial criterion has been used.
Alltheembeddedtiawevaluationchartsinthishandbookwereconstructed using acceptance criteria (2), for ease of use, as well as to obtain the A
wwmwe 1-2
i maximum benefit, since these criteria will generally be less restrictive for embedded flaws. '
1.1.3 CRITERIA BASED ON FLAW SIZE The code acceptance criteria stated in IWB-3611 of Section XI. Namely, a
f 1 0.1 a c For normal conditions (upset &testconditionsinclusive) and af < 0.5 ag For Faulted Conditions (EmergencyConditioninclusive) where
=
af The maximum size to which the detected flaw is calculated to grow at the end of the next inspection time, as applicable.
=
a c The minimum critical flaw size under normal operating conditions (upset and to: conditions inclusive)
=
ag The minimum critical flaw size for initiation of nonarresting
~
growth ur. der postulated faulted conditiuns. (emergency conditionsinclusive)
To determine whether a flaw indication is acceptable for continued service without repair, both criteria must be met simultaneously. However, both criteria have been considered in advance before the charts herein were ,
constructed. Only the more restrictive results ware used in these charts.

1.1.2 CRITERIA BASED ON STRESS INTENSITY FACTOR The term stress intensity factor (Kg ) is defined as the driving force on a crack. It is a function of the size of the crack and the applied stresses, as wt H As the overall geometry of the structure. In contrast, the fracture to6gh m s (K g ,, Kic) is a measure of the resistance of the material to prcpagation of a crack. It it a material property, and a function of tcuperature.
To determine whether a surface flew is acceptable for continued service without repair, both criteria must be met simultaneously. However, both
. criteria have been considered in advance before the charts herein were constructed. Only the more restrictive results were used in these charts.
As mentioned in the prece, ding paragraphs, the criteria used for the evaluation of embedded flaws, surface flaws of the nozzle' safe-eni, and most outside surface flaws are from IWB-3612 of Section XI. The criteria are:
K K<S Fornormalconditions(upset &testconditionsinclusive)
I ~ 60 K
K; < For 'aulted conditions (emergency conditions inclusive)
.,e,e
=
K g The maximum applied stress intensity factor for the flaw size af to .vnich a detected flaw will grow, during the conditions under consideration, to the next inspection. -

l I 1.1.3 PRIMARY STRESS LIMITS j in addition to satisfying the fracture criteria, it is required that the j primary stress limits of ASME Code Section !!!, paragraph NB-3000 be f
] satisfied. A local area reduction of the pressure retaining mortrane must be i used, equal to the area of the indication, and the stresses increased to i reflect the smaller cross section. All the flaw acceptance tables provided in S
this handbook have included this consideration, as demonstrated in the j technical basis document (1).
. 1.2 GEOMETRY j , The geometry of the reactor vessel is shown in Figures 1-2 through 1-6. The
- cladding on the inside of the vessel has been neglected in the stress analysis
! and heat transfer calculations for normal and upset conditions, and has been accounted for by adjusting the film coefficient for the emergenci and faulted conditions. The outside surfaces have been assumed to be insulated. The notation used for both surface and embedded flaws in this work is illustrated i in Figure 1-7, and repeated in each of the sections of the Appendix, i

SECTION 2 LOAD CONDITIONS 2.1 TRANSIENTS FOR THE REACTOR VESSELS The design transients for the Zion, Byron and Braidwood reactor vessels are listed in Table 2-1. Both the minimum critical flaw sizes, such as a, under normal operating conditiens, or ag under faulted conditions for criteria (1) of IWB-3611, and the stress intensity factors, K g for criteria (2) of IWB-3612 are a function of the stresses at the cross section where the flaw of interest is located, along with the material properties. Therefore, the first
' step for the evaluation of a flaw indication is to determine the appropriato ' limiting load conditions for the location of interest.
It should be noted that the Zion plants were designed to a slightly cifferent set of transients than the Byron /Braidwood units, because of different construction dates. Although the design transients are not identical, as can ! be seen in table 2-1, they are very similar. Ir. general, the transients for the Byron and Braidwood plants are more numerous but less severe than those for Zion. The transiente for the later plants are generally more accurate, because they reflect greater operating experience. For this reason the Byron /Braidwood transients have been used in the evaluation charts for all six reactor vessels. - The selection of the most limiting transient for normal / upset / test conditions was straightforward. The transient with the highest surface stress in the area where the flaw was postulated was chosen as the worst case. Note that this can result in a different limiting transient for an inside flaw as opposed to an outside flaw, as may be seen in he detailed treatments of the ' individual locations. The transients listed in 6ese tables are the governing ones for the region involved, regardless of the .riterion used to construct the flaw evaluation charts, (either'the criteria on flaw size (section 1-1,1) or on applied K3 (section 1-1.2)). The selection of the most limiting emergency and fa,ulted condition transient is discussed in section 4 of the technical basis occument (1).

3379s/11t644 it 2-1
. l For flaws near the outside surface of the vessel separate considerations are required, since most of the thermal transients which occur affect the inside surface, not the outside surface, which is insulated. Therefore, allowable flaw indications at the inside surface are generally smaller than those on the outside surface, as may be seen in the individual charts to fo' low in the Appendix.

3- 1 s SECTION 3 FATIGUE CRACK GROWTH 1 In applying code acceptance criteria as introduced in Section'1, the final j-flaw size af used in the criteria is defined as the minimum flaw size to
- which the detected flaw is calculated to grow at the end of the design life, i _or until the next inspection time. In this handbook, inspection periods of 10, 20 and 30 years are assumed.
4 These crack growth calculations have been carried out for all the key regions l in the Zion, Byron, and Braidwood reactor vessels. This sectica will examine i the calculations, and provide a brief description of the methodology used as l well as the assumptions. A more detailed discussion is contained in the
- _ technical basis document (1).
! The analysis procedure involves postulating an initial flaw at shscific
- regions and predicting the growth of.that flaw due to an imposed series of l ' loading transients. The input required for a fatigue crack growth analysis is basically the information necessary to calculate the parameter AKg, which l depends on crack and structure geometry and the range of applied stresses in
) the area where the crack exists. Once AKg is calculated, the growth due j to that particular stress cycle can be calculated by equations given in Figure - 3-1. This increment of growth is then added to the original crack size, and
- - the analysis proceeds to the next transient. The procedure is continued in j this manner until all the transients expected - occur in the period of l evaluation have been analyzed.
l The transients considered in the analysis are all the design transients
- i contained in the vessel equipment specification, as shown in Section 2. These transients are spread equally over the design lifetime of the vessel, with the exception that the preoperational tests are considered first. Faulted conditions are not considered because their frequency of occurrence is too low j to affect fatigu,e crack growth.
4 4 em O l ! 3379s/111500:10 3-1 i I
Crack growth calculations were carried out for a range of flaw depths, and three basic types. The first two were a surface flaw with length equal to six times its depth and another with length equal to twice the depth. Next was a continuous surface flaw, which represents a wirst case for surface flaws, and the last type was an embedded flaw, with a range of shapes and locations. For all cases the flaw was assumed to maintain a constant shape as it grew. The expressions used for calculating stress intensity factors for the various flaw types are documented in the technical basis document.(1) The crack growth rate curves used in the analyses were taken directly from Appendix A of Section XI of the ASME Code. Water environment curves were used for all inside surface flaws, and the air environment curve was used for
' embedded flaws and outside surface flaws. ,
The reference crack growth curves for water environments are shown in Figure 3-1, and growth rate is a function of both the applied stress intensity factor range, and the R ratio (Kain/Emax) f r the transient. The crack growth rate reference curve for air environments is a single curve, with growth rate being only a function of applied AK. This reference curve is also shown in Figure 3-1. This figure appeared in the 1980 edition of the ASME code, and review of current research results indicates it is unlikely to change for many years. S e O 3179s/111544 10 3-2

SECTION 4 CRITICAL FLAW SIZE CALCULATIONS 4
4.1 INTRODUCTION
1 The key parameters used in the evaluation of any indications discovered during inservice inspection are the critical flaw depths required for the evaluation , j of an indication in any given location; first, that for the governing nor. mal upset and test conditions (a )g and second, that for the governing emergency-and faulted-conditions (ag).
- Critical flaw sizes have previously been calculated for postulated inside semi-elliptical flaws having a length equal to six times their depth. To allow the evalua' tion of indicatiens af various shapes, critical flaw sizes are calculated for embedded flaws as well as surface flaws of other shapes.
4
- The selection of the governing transient for normal, +pset, and test conditions can be done easily based on the highest surface stress in~the area of interest. For emergency and faulted conditions, this choice is not as
, straightforward as a result of recent developments on the pressurized thermal shock issue. Therefore the governing transients were chosen only after careful study of this issue, and the deteils of this work are provided in [1]. 4.2 STRESS INTENSITY FACTOR CALCULATIONS l One of.the key elements of the critical flaw size calculations is the determination of the driving force or stress intensity factor. This was done
- for ecch of the regions using expressions available from the literature. In .
4 all cases the stress intensity factor for the critical flaw size calculations utilized a representation of the actual stress profile rather than a 4 linearization. This was necessary to provide the most accurate determination possible of the critical flaw size, and is particularly important for consideration of emergency and faulted conditions, where the stress profile is
; generally nonli'near and often very steep. The details of these calculation procedures are provided in reference [1].
s e 4-1 3379s/111544 10
A 4.3 FRACTURE TOUGHNESS
. The other key element in the determination of' critical flaw sizes is the fracture toughness of the material. The fracture toughness has been taken ; directly from the reference curves of Appendix A, Sc tion XI. In the transition te'aperature region, these curves can be represented by the following equations:
l Kg , = 33.2 + 2.806 exp. (0.02 (T-RTNOT+100'F)) Kg , = 26.8 + 1.233 exp. (0.0145 (T-RTNOT+160*F))
- where K g , and K g , are in ks M in.
The upper shelf temperature regime requires utilizatien of a shelf toughness
- which is not specified in the ASME Code. A value of 200 ksi /in
, has been used here for unirradiated regions, which covers all but the beltline .- region. This value is consistent with general practice in such ev'aluations, as shown for example in reference [3] which provides the background and i
technical basis of Appendix A of Section XI. The value of RTNDT used in these toughness equations was taken from the limiting (worst) properties of materials in both vessels, along with irradiation damage trend curves used to I predict end-of-life values, and these determinations are discussed in i reference (1). The upper shelf fracture toughness after irradiation for the Zion units beltline welds was set conservatively at K3 , = 100
- ksi / in, as discussed further in [1].
i , 4.4 RESULTS
- The results of the critical flaw size calculations were used along with the fatigue crack growth results to determine the size flaw which is acceptable based on the criteria of Section XI. These allowable flaw sizes are shown graphically for e'ach region in the charts of Appendix A, with separate figures I for surface and embedded flaws in each region.

l APPENDIX A FLAW EVALUATION INTRODUCTION TO EVALUATION PROCEDURE The evaluation procedures contained in ASME Section XI are clearly specified in paragraph IWB-3600. Use of the evaluation charts herein follows these procedures directly, but the steps are greatly. simplified. Once the indication is discovered, it must be characterized as to its location, length (t) and depth dimension (a) for surface flaws, (2a) for
' embedded flaws, including its distance from the nearest surface (clad-base metal interface or outside side) (S) for embedded indications. This characterization is discussed in further detail in paragraph IWA-3000 of Section XI. ,
The following parameters must be calculated from the above dimensions to use the charts (see Figure 1-6 in the main text): o Flaw shape parameter, f o Flaw depth parameter, 'g , o surfaceproximityparameter(forembeddedflawsonly),f where t = wall thickness of region where indication is located (not , including clad thickness) t = length of indication, a = depth of surface flaw; or half depth of embedded flaw in the width direction A-1 mm.mim in
6 e ' distance from flaw centerline to surface (for embedded flaws only, 8 = S + a) S = smallest distance from edge of embedded flaw to surface Once the above parameters have been determined and the determination made as to whether the indication is embedded or surface, then the two parameters may be plotted directly.on the appropriate evaluation chart. Its location on the chart determines its acceptability immediately. Important Observations on the Handbook Charts Although the use of the handbook charts is conceptually straight forward, experience in their development and use has led to a number of observations which will be helpful. Surface Flaws ' An examt . edbook chart for surface flaws is shown in Figure A-1. The flaw indicativ.. .trameters (whose calculation is described above) may be plotted directly on the chart to determine acceptability. The lower two curves shown (labelled code allowable limit) are simply the acceptance standards from IWB 3500, which are tabulated in Section XI. If the plotted point falls below these lines, the indication is acceptable without analytical justification having been required. If the plotted point falls between the code allowable limit lines, and the lines labelled " upper _ limits of acceptance by analysis" it is acceptable by virtue of its meeting the requirements of IWB 3600, which allow acceptance by fracture analysis. (Flaws between these lines would, however, required future inspection per IWB-2420 of Section XI.) The analysis . used to develop these lines is documented in the companion technical basis document (1). There are three of these lines shown in the charts, labelled 10, 20 and 30 years. The years indicate for how long the acceptance limit applies, from the date that a flaw indication is discovered, based on fatigue crack growth calculations. e 3370s/1115M 10 A-2
.o. o. . As may be seen in Figure A-1, the chart gives results for surface flaw shapes
-up to a semi-circular flaw (a/t = 0.5). For the unlikely occurrence of l flaws whick the value of a/t exceeds 0.5, the limits on acceptance for a/t = 0.5 should be used. J l
l Embedded flaws An example chart for embedded flaws is shown in Figure A-2. The heavy diagonal line in the figure can be_ used directly to determine whether the indication should be characterized as an embedded flaw or whether it is sufficiently close to the surface that it must be considered-as a surface flaw (by the rules of Section XI). If the flaw parameters produce a plotted point below the heavy diagonal line, it is acceptable by analysis if the point is below the appropriate a/t limit line. If it is above the line, it cannot be justified by analysis, and is, therefore, not acceptable. For cases where there are several acceptance limit lines, interpolation between adjacent lines is recommended. A worked example is provided as embedded flaw example 5. The outermost lines should be used as the limits, with no interpolation beyond them. For example, for a/t values greater than 0.333, use the line_for a/t = 0.333-in the figure, and-for a/t values less than 0.167, use the line S r a/t'= 0.167. Beyond these outer limits, the analyses have shown that the sensitivity to flaw shape is small. _ For cases where there are no branching limit lines below the hea~vy diagonal line (see Figure A-2.6 for example) then all flaws classified as embedded are
-acceptable. The only limitation is, as discussed in reference {1):
f<0.25 - Note that the embedded flaw evaluation charts are applicable for flaws near either the inner or outer vessel surface, and the parameters "S" and "6 are defined from the nearest surface. O
~
A-3 m mim in
a . Another important observation is the procedure to be used for an eabedded flaw whose plotted point falls above the heavy diagonal line, and must therefore be considered a surface flaw. An example of this is provided in " Embedded flaw Example 1" on Page A-6, but it is important to note that when this must be done, the depth of the flaw is redefined. The new oopth is aqual to 2a + S, as shown in the example, which becomes the effective crack depth a* to be used in the surface flaw chart in such cases. General Observations Detailed examples of the use of the charts for both surface and embedded flaws are presented below, for a specific cross section. Some points are worthy of note for locations between the cross sections which have .been analyzed. A flaw indication between two adjacent cross sections should use acceptance criteria interpolated linearly between the two appropriate charts. Surface Flaw Example 1 Suppose an indication has been discovered which is a surface flaw, and has the following characterized dimensions: a = 0.396 in, t = 1.98 in. - t = 8.6 in. The flaw parameters for the use of the charts are {= 0.046 { = 0.20 Plotting these parameters on Figure A-1 it is quickly seen that the indication is acceptable by analysis. To justify operation without repair it is necessary to submit this plot along with the technical basis document (1) to the regulatory authorities. O mwmm. A-4

Embedded Flaw Example 1 l A longitudinal
- embedded flaw of 1.75" x 5.00", located within 0.10" from the surface, was detected. Determine whether this flaw should be considered as an embedded flaw.
2a = 1.75" S = 0.10"

6 S + a = 0.10 + 1/2 (1.75) = 0.975

- Note: longitudinal herein means relative to the vessel or nozzle centerline, not the weld length. For the nozzle inner radius, and other regions l of a nozzle, longitudinal is relative to the nozzle centerline.

-=
g = 0.101 ( = Eg 9fE40.113 Since the plotted point (X) is abeve the diagonal line, the flaw must be considered a surface flaw instead. 2 Now, since the flaw must be considered as a surface flaw, the depth must be redefined as the distance from the surface to the deepest point of the flaw. This is equivalent to circumscribing the embedded flaw with a semi elliptic em A-5 us...m m a
surface flaw. Operationally, the paramet'ers are recalculated as follows. Defining a* as the corrected crack depth for the surface flaw,
u a* = 2a + S = 1.85' -

7 = 0.215 h=0.37 . Referring to Figure A-1 for the surface flaw, it is quickly seen that this flaw is much too large to be acceptable, and must be repaired. Embedded Flaw Example 2 (Point A) Suppose an indication has been discovered which is embedded, and has the following characterized dimensions: 2a = 1.0 in, t = 1.5 in, t = 9.16 in. S = 0.75 in. - Calculating the flaw parameters, e have: {= 0.0545 y = 0.333 6 = 5 + a = 1.25 in. (=0.136 Plotting these parameters on the embedded flaw evaluation chart, Figure A-2 it may be quickly seen that the indication is embedded, and is acceptable by analysis (point A), since it lies below the a/t = 0.333 limit case.

Embedded Flaw Example 4 (Point C) A longitudinal embedded flaw of 1.50" x 5.38" was detected at a distance S = 1.40 in, underneath the surface. Evaluate the flaw for code acceptance for continued service without repair. The flaw geometry parameters are determined as follows: t = 8.63" S = 1.40" 6 = S + a = 2.15" t = 5.38" and a = 1/2 x 1.50"

Embedded Flaw Example 5 (Point C) _ Use the same characterizing dimensions as example 4, except that the length of the flaw to be 2.6 inches. This example will illustrate the method of linear l interpolation to be used with the embedded flaw charts. 4 The flaw geometry parameters are: t = 8.63" 2 T S = 1.40' , c 6 = S + a = 2.15' ' t = 2.6" a = 0.75" The flaw parameters are therefore: i (=0.25 l a 0.750 7 = g = 0.29 {=0.087 4 Plotting the point as before (Point C) we tae that it lies between the two limit lines in Figure A-2, and the aspect ratio (a/t) is also between the two limiting lines aspect ratios. Therefore, linear interpolation is done, as illustrated in the sketch on this page. Interpolation shows that the flaw is acceptable. A j . A-9 3179s 4 30309 10

l A-11 TOP HEAD DONE TO RING WELD The stress distribution at the top flange junetion is unique since high boltup ! stresses are applied in this region in addition to the regular pressure and i thermal stresses. Moreover, the governing transient which creates the worst stresses at the inside surface is different from that for the outsida surface. The orientations of the maximum stresses at both the inside and the eutside surfaces are also different, not to mention in different environments. As a consequence, fracture mechanics investigation on both surfaces becomes necessary. (See Figure A-11.1) The governing normal and upset transient at the inside surface was found to be loss of flow, whereas that at the outside surface was found to be heat-up.
/-11.1 SURFACE FLAWS The following parameters must be determined for the surface flaw evaluation at both inside and outside surfaces.
o Flawshapeparameterf o Flawdepthparameter{ where a - the surface flaw depth detected (in.) 1 - the surface flaw ',ngth detected (in.) t - wall thickness at the top flange junction (t = 7.19 in.)

.o e 4 A-13 LOWER FLANGE TO SHELL WELD l As found for the top head dome to flange weld the stress analysis and fracture evaluation for this region are rather complex. (SeeFigureA-13.1) The governing normal and upset transient at the inside surface was found to be cooldown, whereas that at the outside surface to be heat-up, rerpectively. A-13.1 SURFACE FLAWS The following parameters must be determined for the surface flaw evaluation at
. both inside and outside surfaces with charts.

A-13.2 EMBEDDED FLAWS l As the surface flaw evaluation charts d3 scribed in paragraph A-13.1, the evaluation charts for the embedded flaws near either the inside or outside surfaces have been constructed separately. The locations of the embedded flaws for both inside and outside surfaces of the lower flange ju'nction are ! depicted as shown in Figure A-13.1 also. l
- The basir data used for the evaluation of the embedded flaws for either side of the 'awer flange to shell weld are summarized as follows
