SUMMARY
This handbook has been prepared to allow quick, yet accurate, assessment of:
i indications which may be discovered.during inservice inspections of the Joseph Farley Units 1 and 2 steam generators and pressurizers. This assessment i
capability is provided in the form of charts for selected regions of the steam generators and pressurizers.
These are contained in Appendix A of this r
document. Appendix A begins with a simple example demonstrating use of the evaluation charts; followed~by a-section for each region of the steam generator and pressurizer. details of the derivation of the charts are provided.in the technical basis document (1).
The main-body of this handbook-provides brief summaries of the various calculati'ons carried out in developing-the charts. To evaluate the ~ acceptability of an. indication, the user may proceed directly to Appendix A.

SECTION 1 INTRODUCTION This flaw
- evaluation handbook has been designed for the evaluation of indications which may be discovered during inservice inspection of the Joseph Farley Units 1 and 2 steam generators and pressurizers. 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 (2), and is documented in a companion background and technical basis report (1). Use of the handbook.
will allow the acceptability of much larger indications than would be allowable by only using the standard tables of ASME Section XI (2). A schematic representation of the flaw evaluation process of ASME Section XI Appendix A is provided in figure 1-1.
This flaw evaluation handbook has been developed as a direct implementation of-the analytical requirements of Section XI.
In all cases'the latest. material properties and analytical criteria have been used and the appropriate' code editions appear in (2). These handbooks have been designed for use throughout the operating lifetime of the plants, during which time the applicable edition of section XI will change a number of times.
The handbook is applicable to low alloy steel base metal and welds in' the Joseph Farley Units 1 and 2 steam generators and pressurizers. The geometry of each of these regions is shown in figures 1-2 and 1-3, and repeated at the appropriate section of the Appendix.
Flaw charts are provided for' flaws oriented along each of the welds in both the pressurizers and steam generators. Charts are provided for inside and outside surface and embedded flaws in each region, and for nozzle corner surface flaws for each.cf.the-l-
nozzles.
- The use of the term " flaw-in this document shoula be taken to be synonymous l
with the term " indication" as used in Section XI of the ASME. Code.
I m i.m7n n io.

m
t Handbook charts have been constructed for each of the following regions in Joseph Farley Units 1 and 2.
The steam generator:
o Tubesheet to channel head weld region o
Tubesheet to stub barrel weld region o
Stub barrel intermediate seam t
o Lower shell to cone weld region o
Upper shell to cone weld region o
Upper shell welds o
Upper shell to dome weld region o
Feed ster nozzle to shell weld region o
Steam outlet nozzle to shell weld region o
Primary nozzle safe end welds The pressurizer:
o Upper shell to head weld o
Upper shell circumferential welds o
Upper shell longitudinal welds o
Lower shell circumferential welds o
Lower shell longitudinal welds o
Surge nozzle to head weld o
Spray nozzle to head weld o
Safety and relief nozzle to head welds The highlight of the handbook is the design of a series of. flaw evaluation charts for both surface flaws and embedded flaws.
Since the characteristics of the two types of flaws are different,: the evaluation charts are l
distinctively different in style. Examples have been:provided in the introductory section of the Appendix.
The flaw evaluation charts were designed based on-the.ASME Code Section XI l
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 l
Code analytical criteria instantaneously, and no follow-up hand calculation is required. Most important of all, no fracture mechanics knowledge is needed by the user.

i 1
The flaw evaluation charts are provided in Appendix A of this document.
The J
notation used for both-surface and embedded flaws in this work is illustrated in figure 1-4, and is repeated in each section of the Appendix.
For flaw i
evaluatien of an indication discovered in an inspection, turn directly to the Appendix.
j 1.1 Code Acceptance Criteria l
f There are two alternative sets of flaw acceptance criteria for continued service without repair in paragraph IWB-3600 of ASME Code Section XI.
- Namely, I
1.
Acceptance Criteria Based on Flaw Size (IWB-3611) 2.
Acceptance Criteria Based on Stress Intensity Factor. (IWB-3612) j 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 flaws in many cases, in all cases in this handbook, the most beneficial criterion has been used.
All the embedded flaw evaluation charts in this handbook were constructed using acceptance criteria (2), for ease of use, as well as to obtain the maximum benefit, since these criteria will generally be less restrictive for embedded a
1 flaws.
i 1.1.1 Criteria Based on Flaw Size 0
The Code acceptance criteria are stated in IWB-3611 of Section XI.
- Namely,
.1 a For Normal Conditions a
f c
(Upset & Test Conditions inclusive) and af
.5 a$
For Faulted Conditions (Emergency Condition inclusive);
where af=
The maxim'um size to which the detected flaw is calculated to grow at the end of the design life, or till the next inspection tim'e, as applicable.
nsmoncu io 33
The minimum critical flaw size under normal operating a =
c conditions (upsetandtest.conditionsinclusive):
a3=
The minimum critical flaw size for initiation of nonarresting growth under postulated faulted conditions.- (emergency conditionsinclusive)
To determine whether a surface flaw is acceptable for-continued service without repair, both criteria must be met simultaneously. However, both criteria have been considered in advance in construction of the charts herein. Only the most restrictive results were used in-these charts.
1.1.2 CRITERIA BASED ON STRESS INTENSITY FACTOR-
'The term stress intensity factor (K ) is defined as the dEivingLforce on a j
- crack, it is a function of the size of the crack and the applied stresses, as well as the overall geo. metry of the structure.- In contrast, the fracture 4 toughness (K;,, Klc) is a measure of the resistance of the material to-propagation of a crack.
It is a material-property and a function of temperature.
The criteria from IWB-3612 of Section XI are:
K 3<S for normal, upset and test conditions.
K
/ 10 K
K; < S for emergency and facited conditions.
/2 where Kj=
The maximum applied stress intensity factar for-the flaw size af to which a detected flaw will grow, during the conditions-under consideration, to the next inspection..
y
j l
K;,=
Fracture toughness based on crack arrest for the corre'sponding-crack tip temperature.
Kic =
Fracture toughness based on fracture initiation for the corresponding crack tip temperature.
To determine whether a surface flaw is' acceptable for continued service without repair, both criteria must be met simultaneously.
However, both criteria have been considered in advance when the charts herein were constructed. Only the most restrictive results were used in these charts.
1.1.3 PRIMARY STRESS LIMITS In addition to satisfying the fracture criteria, it is required that the primary stress limits of Section III, paragraph NB 3000 be satisfied.
A local area reduction of the pressure retaining, membrane must be used, equal to the~
original area less the area of the indi:ation, and the stresses _ increased to reflect the smaller cross section. Al' the flaw acceptance tables provided in this handbook have included this consideration as demonstrated in the 4
l technical basis document (1).
1.2 SCOPE OF THIS WORK l
d l
Finite element stress analyses of the Joseph Farley Units 1 and 2 steam' generators and pressurizers under various transients have been' performed by
.i l
Westinghouse,-Nuclear Components Division, Pensacola, Florida'-for.this-l project. Fracture mechanics analyses were performed for v'arious~ aspect' ratios of both surface and embedded flaws using the results of stress analyses:
associated with-emergency, faulted, normal, upset and test conditions.
Based on the results of-the fracture. mechanics. analyses surface flaw and embedded-flaw charts have been developed.
The' fracture and fatigue crack growth evaluations carried out to develop the-handbook charts have employed the recommended procedures and-material pi r erties for low alloy steels, as contained in Section'XI, Appendix A.

SECTION 2 LCAO CONDITIONS The loading conditions used in the analyses described herein were taken directly from the equipment specification for each of the components covered.
The fracture analysis methods are the most advanced which are now available, and the material properties are the latest available properties contained in the ASME Code.
The transients for the steam generators are taiulated in-Table 2-1 and those for the pressurizers are given-in Table 2-2.-
Both the minimum critical flaw sizes, for criteria (1) of IWB-3611, and the stress intensity factors, for criteria (2) of IWB-3612, are a function of the stresses at the cross-section where the flaw of ir.terest is located. Therefore, the first step in the construction of the charts for the evaluation of a flaw indication is to determine the appropriate limiting load conditions for the location of interest.
Tho basis for the selection of the most limiting normal / upset / test conditions is straightforward. The transient with che highest surface stresses (thermal and pressure stresses combined) in the region of the indication was chosen as the werst case.
For flaws near the outside surface of the vessel-separate considerations are required, since most of the thermal transients affect-the s
4 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-follow in the Appendix.
The selection of the worst emergency / faulted transient was also based on the highest stresses, but combined with the-lowest temperature. This has been discussed in detail in the Technical Ba.is document (1).

SECTION 3-FATIGUE CRACK GROWTH l
In applying code acceptance criteria as introduced in Section 1, the final flaw size af used in criteria (1) is defined as the minimum flaw size to which the detected flaw is calculated to grow at the end of the design life, or until the next inspection time, in this handbook, inspection every 10 years is assumed.
These crack growth calculations have been carried out for all the key regions in the Joseph Farley Units 1 and 2 steam generators and pressurizers.
This section will examine the calculations, and provide a brief description of the methodology used as well as the assumptions. A more detailed discussion is contained in the Technical Basis document-(1).
The crack growth calculations reported here are extensive because a range of flaw shapes have been considered to encompass the range of flaw shapes which could be encountered in service.
The analysis procedure involves postulating an initial flaw at specif u regions and predicting the growth of that. flaw due to.an imposed series of loading transients. The input required for a fatigue crack growth analysis is basically the information necessary to calculate the parameter K;, which depends on the crack and structure geometry and the range of applied stresses in the area where the crack exists.
Once K 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 this manner until all the transients ex-acted to occur in the period of evaluation have been analyzed.-
The transients considered in the analysis are.all the design transients contained in the appropriate steam generator or pressurizer equipment 1
l-specification, as shown in Section 2.
Thew tra %1ents are spread equally over the design lifetime of the vessel, with the exception that the-1 36 sis eoisoso io 3-1 I
i e-
preoperational tests are considered first.
Faulted conditions are not considered because their frequency of occurrences is too low to affect fatigue
[
crack growth.
Crack growth calculations for the steam generator and pressurizer were carried out for a range of flaw depths and three' basic types. The first type was a surface flaw with length equal to six times its depth.
The second was a continuous surface flaw, which represents a worst case for surface flaws.
The third was an embedded flaw. For the steam generator, the length was assumed equal to three times its width (through wall dimension), while for the pressurizer the length was assumed equal to five times its width.
This difference had little effect on the magnitude of crack growth calculated.
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 (Xmin/Kmax) for the transient.
The crack growth rate reference curve for air environments is a single curve, with growth rate being only a function of'appliec' K.
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.

SECTION 4 CRITICAL FLAW SIZE CALCULATIONS
4.1 INTRODUCTION
The key parameters used in the evaluation of any indications discovered during inservice inspection are two critical flaw parameters required for the-evaluation'of an indication in any given location, The first of these is calculated using stresses from governing normal, upset, and test conditions.
The second is calculated based on stresses for the governing emergen'cy and faulted conditions. The parameters based on those conditions correspond to the two ASME code criteria defined in Section 1.1.1.
l Critical flaw sizes were calculated for postulated inside_ surface semi-elliptical flaws having a length equal to six times their depth.
To allow the evaluation of indications of various shapes, critical flaw sizes are i
calculated for embedded flaws as'well as surface flaws of other shapes.
Critical flaw sizes were :alculated for emergency-and faulted as well as normal-and. upset conditions. Hydro and leak test-conditions were considered separately for the steam generators, since their: severity can be controlled by i
temperature.
The selection of the goserning transient for emergency faulted, normal,. upset, and test conditions can be done easily based on the results of the available stress analyses.
The details of-this work are provided in the technical basis document (1).
4.2 STRESS INTENSITY FACTOR CA!.CULATIONS 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 I
for each of the regions using expressions available.in the literature.
In all l
cases the stress Intensity facter for the critical flaw size calculations utilized a representation of the actual stress profile rather than a lincarization.
This was necessary to provide the most accurate determination possible of the critical flaw size and is particularly important for
'l l
3His /013C9010 4.}
1 Il I
consideration of emergency and faulted conditions where the stress profile is generally nonlinear and often very steep.
4 4.3 FRACTURE TOUGHNESS Tha 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, ASME Section XI..
In the transition temperature region these curves can be represented by the following 4
equations:
4 1'
Kic = 33.2 + 2.806 exp. (0.02 (T-RTNOT + 100*F))
i K;, = 26.8 + 1.233 exp. (0.0145 (T-RTNOT + 160*F)]
and K, are in ksi / in, where K;c g
j i
The upper. shelf temperature regime requires utilization of a shelf toughness which is not specified in the ASME Code. A value of 200 ksi /in has been used here. This value is consistent with general practice in such evaluations, as shown for example in reference (3) which provides the background and technicalL basis of Appendix A of ASME Section XI.
The value of RTNDT used in these toughness equations was taken from the limiting properties of materials in both the steam generator and pressurizer and these values 'are obtained i
directly from Nuclear Components Division, Pensacola, Florida.- The limiting-RT f r the steam generators was found to be 30*F for the base metal and NDT 10*F for the welds. For the pressurizer, the limiting RTNDT was also found to be 30'F for the base metal and 10*F for.the welds.

i APPENDIX A FLAW EVALUATION A-1 INTRODUCTION TO EVALVATION PROCEDURE The evaluation procedures contained in ASME Section XI are clearly specified
[
in paragraph IWB-3600.
Use of-the evaluation charts herein follows these i
procedures directly, but d.e steps are greatly simplified, a
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 clad-base metal interface-(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 tho'above dimensions to use the charts (see figure 1-4 in section 1):

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
,j be plotted directly on the appropriate evaluation chart.
Its location on the
~
chart determines its acceptability immeo'dely.
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 t
An example handbook chart for surface flaws is shown in figure A-1,1.
The t
flaw indication parameters (whose calculation is described above) can be plotted directly on the chart to determine acceptability.
The lower curve shown (labelled Code allowable limit) is simply the acceptance standards from IWB 3500, which are tabulated in Section XI.
If the plotted points. fall 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 labeled " upper limits of acceptance" 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, require future monitoring per IWB 2420 of Section XI).
The analysis used to
(
develop these lines is documented in the companion technical basis d'oeument
[1]. There are three of these lines shown in the charts,-labeled 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 l
calculations.
As may be seen in figure A-1.1, the chart gives results-for surface flaw h
shapes up to a semi-circular flaw (a/t.= 0.5).
For-the unlikely occurrence of flaws for which the value of a/t exceeds 0.5, the-limits on acceptance for a/t = 0.5 should be used.
The upper limits of_ acceptance-have been set at (a maximum of)' twenty percent of the wall thickness in all cases, as discussed in Section 5. of (1).
e,zono.o io A-2 i
l Embedded Flaws An example chart for embedded flaws is shown in-figure A-1.2.
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 sutTiciently 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 th,e heavy diagonal line, it is acceptable by' analysis per-[1] 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.
'l The flaw evaluation charts for. embedded flaws are presented in a form which does not allow a direct presentatiori of the standards from'Section XI,.
IWB 3500.
For comparison purposes, these standards have been presented graphically in Figure A-1.3.
If an indication is below the-appropriate standards limit of Figure A-1.3, it is acceptable without analytical j
evaluation.
For cases.where there are no branching limit lines'below the heavy diagonal line (see figure A-3.5 for example) then all flaws classified as embedded' are i
acceptable.
The.only limitation is, as discussed in Section 6 of reference
~
(1):
f<0.25 l
Note that the embedded flaw evaluation charts are applicable for. flaws near either the inner or outer surface, and the parameters "S" and "6" are defined from the nearest surface.
Another important observation is the procedure to be used for an embedded 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", but it is important to note that when this must be done, the dept'h of the flaw is redefined.
The'new depth is equal to-2a + S, as shown in the l
example, which becomes the effective crack depth a* to be used in the surface flaw chart in such cases, mmonm io A-3
General Observations
\\
Detailed examples of the use of the charts for both surface and embedded flaws ara presented below, for the specific cross section.
Some points are worthy of note for locations between the cross sections which have been analyzee.
A flaw indication between these two cross sections should use acceptance criteria interpolated linearly between the two appropriate charts..Similar procedures should be followed for interpolation -between other regions.
Modification of Hydrostatic and Leakage Test Temperatures if an indication is discovered in the steam generators which is. justified for further service without repair by the flaw evaluation charts of this report, an increasa in the minimum temperature at which the hydrotest and leak tests must be conducted may be necessary to ensure the required margins of Section XI are maintained; Charts are provided for determination of this temperature in each of sections A-2 to A-10.
The required temperature is a function of the size and location of the indications discovered. Separate treatments have been developed for embedded and surface indications.
4 The charts in these sections provide a simple method for determining the required minimum temperature for any subsequent hydrostatic or leakage tests.
Once an indication has been characterized, its size and location within the' wall of the vessel (5/t) determir.e the allowable hydrostatic or leakage test I
temperature.. This may be done by-simply plotting the indication on the appropriate chart. Separate charts have been provided for surface.and embedded indications.

Surface Flaw Example 1 Suppose an indication has been discovered which is a surfe.ce flaw and has the following characterized dimensions:
a = 0.30 in, j
t = 1.5 in.
l t = 6.69 in, j
l The flaw parameters for the use of the charts are:
{ = 0.045 (4.5%)
f=0.20 j
i Plotting these parameters on figure A-1.1 it is quickly seen that the indication is acceptable by analysis per (1).
To justify = operation without repair it is necessary to submit this plot along withithe Technical Basis document (1) to the regulatory authorities.
Embedded Flaw Examole 1 A longitudinal embedded flaw of 1.75" x 5.00", located'within 0.575" from the surface, was detected. Determine whether this flaw should be-considered as an embedded flaw.
2a = 1.75" S' = 0.575" 6 = S + a = 0.575 + 1/2 (1.75) = 1.45" t = 6.69" t = 5.0"

Since the plotted point-(X) is above the diagonal line, the flaw must be j
considered a surface flaw. Now, since the flaw must be considered as a-surface flaw, the. depth must be redefined as the distance from the surface to
-l the deepest point of.the flaw.
This is equivalent to circumscribing the
]
embedded flaw with a semi-elliptic surface flaw.- Operationally, the parameters.are recalculated as follows. Defining a* as the corrected crack-depth for the surface flaw, 1

Calculating the flaw parameters, we have:

E amdded Flaw Eian.ple 3 (Point B) t Suppose an indication has been discovered which is embedded, and has the i
following characterized dimensions:
2a = 1.47" a = 0.73" t = 2.20" S = 1.325 t = 9.16" Calculating the flaw parameters, we have:

{=0.33 6 = S + a = 2,06
)
(=0.225 Diotting these parameters on figure A-1,2 (point B) we see that the indication is acceptable, since it falls below the line which is applicable to a/t =
0.333..(Note that if a/t = 0.16), for example, the indication would not be.
acceptable, since p9 int B would lie above that line, as may be seen in the j
figure.)

Embedded Flaw Example 4 (Point C)
A longituoinal embedded flaw of 1.15" x 5.38" was detected at a distance S =
1.075 in, underneath the surface.
Evaluate the flaw for code acceptance for continued service without repair.
The flew geometry parameters are determined as follows:
t = 6.69" S = 1.075" 6 = S + a = 1.65" t = 5.38" and a = 1/2 x 1,15:
=.575"
(=(h)=0.247 a
0.575 7 = (g ) = 0.107 a
0.575 7 = ( g ) = 0.086 Evaluate the flaw by referring tn figure A-1.2 and plotting the point (as point C).
This is above the code acceptance limit line for a/t = 0.167, which should also be used for a/t < 0.167; therefore, the flaw is not acceptable, and must be repaired.
Note:
The code acceptance lines become identical with the surface / embedded flaw demarcation line with which they link up at points near the surface. Therefore, in figure A 1.2 the code acceptance line for flawsnearthesurface,flessthan0.125,isidenticalwith the " surface / embedded flaw demarcation line up till 1980 Code".

In view of figure A-4.5, an embedded flaw in this figure will be acceptable regardless of its size, shape, and location, as long as { < 0.125 in figure A-4.1.
This determination can be made by plotting the indication parameters in the figure.
If the plotted point falls below the diagonal line mi,4noso io A-26
1 the indication is embedded, and is therefore acceptable.
In addition to this chart, test tsmperature determination charts for both secondary hydro and leak tests have bsen provided.
