Technical Specification Change Request No. 203, Revision 0 Small Volume Eddy Current Indication Disposition

Reference:

A. FPC to NRC letter, 3F0595-05, dated May 31, 1995 B. NRC to FPC letter, 3N0494-21, dated April 26, 1994 C. NRC to FPC letter, 3N1095-21, dated October 24, 1995

Dear Sir:

Florida Power Corporation (FPC) submitted the referenced proposed change to our Technical Specifications on May 31, 1995 (Reference A) as required by a Confirmatory Action Letter (CAL) dated April 26,1994 (Reference B) . That change updated the Once Through Steam Generator (OTSG) Eddy Current (ECT) disposition strategy that we developed and used in Refuel 9, as required by the CAL, to reflect the results of the Refuel 9 inspections and tube pull campaign. Our )

staffs discussed the proposed change during an August 30, 1995 teleconference.

Your staff followed up with a formal Request for Additional Information (RAI) l dated October 24, 1995 (Reference C). A meeting was held in Rockville on i November 17, 1995 to discuss the NRC's concerns on a preliminary, conceptual i level so that we could more effectively respond to the RAI and so each of our  !

technical staffs could more accurately brief their management on how we could and i should proceed. FPC committed to respond to the RAI as soon as possible to l facilitate a meeting which has now been scheduled for December 15. The i attachments to this letter constitute FPC's response to the RAI. We plan to j discuss the responses in as much depth as necessary during the December 15 l meeting. We will be pleased to supplement these responses, as needed, following that meeting '

l U. S. Nuclear Regulatory Commission 3F1295-03 Page 2 The cover letter transmitting the RAI included a general discussion of the staff's initial reactions to our proposal. The issue was also discussed at a November 17, 1995 meeting. That meeting improved our understanding of the nature of your concerns. As noted during the meeting, we certainly agree that any sound proposal must reflect both past experience and adequately deal with likely results of future inspections. We also agree that the limited amount of data with which we are dealing creates a substantial technical challenge in developing a mutually acceptable criteria. This limited data is a result of good 0TSG experience and our attempt to deal with this issue as proactively as possible.

As we stated at the meeting, we may not yet be in full agreement on some points.

For clarity and completeness of the docket we thought it appropriate to respond ,

to them below, i

1) We would not place as much emphasis as the cover letter does in characterizing our proposal as " voltage-based." Signal voltage is used as one input to the evaluation process to add conservatism to our proposal from )

a structural perspective and to provide an appropriate limit from a leakage perspective. We are relying on a conservative estimate of defect dimensions as the structural repair criteria. The proposed approach is consistent with 1 the NRC guidance in Generic Letter 95-05 which encouraged the industry to  ;

continue efforts to improve inspection methods and repair criteria noting l that ones based on physical dimensions are the most desirable when they can be achieved.

2) Signal / noise (S/N) is the ratio of signal attributable to the discontinuity with that attributable to the various amount of other signal (called noise) present in all applications. It has been and is being used as a general indicator of the ability to accurately assign a through-wall (TW) depth estimate to an indication. In the structure of the TSCRN, it may appear to be more significant than it really is. The value of 5:1: was originally chosen to achieve a sizing error of less than 10%; is the value used in past CR-3 inspections; and thus is reflected in the historical data base. The analyst guidelines actually have allowed, and recently encouraged, a best-effort to make "TW calls" on all indications regardless of S/N ratio. This practice (removing a small volume indication with an estimated depth of greater than 40%) may cause us to remove from service some defects that have  ;

sufficient volume to generate a clear signal but which are really not significant from either a leakage or structural viewpoint. At some point, perhaps as we implement the proposed rulemaking in this area, we may be able to agree on a criteria to 'save' these sound tubes as well. It may be possible to eliminate consideration of S/N altogether.

3) We never believed all low S/N indications were Inter-Granular Attac9 (IGA).

We thought we had been careful not to leave others with that impt ession.

We noted from the outset the existence of similar NDE indications at the tube support plates (TSPs) and at free-span locations at several elevations.

We included related information in our previous discussions with the NRC.

During Refuel 8 we were able to remove tube sections from a region (first free-span above the lower tube sheet) where the dominant defect type was found to b. IGA. We did extensive evaluations and developed a most-likely cause and repair strategy. We were unsuccessful in extracting tube segments from other locations where wear would be more-likely (i.e., at TSP interfaces) until the second tube-pull campaign (Refuel 9 in 1994). When

1 U. S. Nuclear Regulatory Commission 3F1295-03 Page 3 i we did so, wear was indeed found. This was reflected in the inspection  !

results we provided in late 1994 (in response to CAL Item 8) and earlier i this year (concurrent with the TSCRN). Nevertheless, we now realize that we were apparently unsuccessful in communicating the presence of wear.

4) The letter includes the statement: "A low S/N ratio is a product of the inspection process and is not a characteristic intrinsic to a particular-mode of degradation." We agree; as long as " mode of degradation" is used to refer to degradation mechanism (cause) as opposed to morphology.

Morphology directly impacts inspection results (signal). We would add that low S/N ratio is fundamentally either due to a low signal OR high noise.

Some of our discussions and the RAI imply that the fundamental cause is high noise. We do not agree that is the case. We have observed at least two degradation mechanisms in the CR-3 OTSG's that produce very low signals for ,

similar reasons (both involve very limited defect volume). Our efforts to l reduce noise are addressed in the associated RAI responses.

l

5) We do not agree with the suggestion that the most appropriate course of action is to revise our proposal to focus solely on IGA. As we stated at the meeting, and as addressed in appropriate RAI responses, we cannot ,

readily distinguish between some of the wear (which we have termed  ;

volumetric as opposed to the more standard tapered-wear) and IGA. After considering the merits of various alternate repair criteria strategies we  ;

continue to believe that the one proposed best deals with the situation at CR-3. We understand that focussing on IGA might have been more l administratively similar to the generic DSM efforts but believe technical merit should outweigh such considerations.

We do agree that our proposal differs from other alternate repair criteria in a number of ways. For some time we even hesitated calling our proposal an alternate repair criteria reflecting our recognition that there were substantial ,

differences. We appreciate the difficulty this may cause. Our proposal is not l based on a highly focussed effort to deal with one degradation mechanism, but 1 rather is an alternate general approach that is directed at handling two defect types with similar morphology. These defect types appear to be generally dormant and are not significant from either a leakage or structural perspective. Rather than forcing our situation to fit a model not well-suited for it we would rather consider other alternatives further. While not fully developed, we would suggest:

a) We could mutually develop reporting requirements that require us to evaluate appropriate figures-of-merit (i.e., measures of growth rate, etc.) for the inspection results our program will continue to obtain. We currently reinspect (with standard bobbin coil) all low S/N tubes each outage.

Trending the average voltage and/or other appropriate values would help assess any fundamental change in the nature of defects we are leaving in-service.

b) The NRC's approval of all or portions of the TSCRN could be limited in duration. If the data to be obtained this outage, other data availability and the time to further review our proposals would benefit the NRC's review we would not object to the approval being for a single fuel-cycle. This would be consistent with some of the other generic efforts. This might also

allow the CR-3. program to continue to evolve. l c) If there are other specific NDE efforts or changes to the various nt:merical values proposed in the TSCRN that would help resolve your concerns we will  ;

Dearadation Specific'Manaaement

1. Describe your long term plans to monitor the morphology of low signal-to-noise-(S/N) indications (e.g., tube pulls, destructive examinations, etc.). Reference 3 states that the B&W Owners Group Steam Generator Coemittee recommended pulling tubes from Oconee Units 1 and 3 in addition to those at Crystal River Unit 3 (CR-  ;

3) .- Describe how 'the results available 'to date from these4 other tube pulls' l

support the conclusions developed based on the' data from the CR-3 tube pulls;  ;

If. the Oconee tube pull data are not: currently available discuss your schedule  ;

and plans for incorporating the data into ?our analyses. . Provide a~ schedule of when the tube pull nondestructive examination comparison study cited on pages 2-2 and 3-6 in Reference 3 will' be available.

FPC's long. term plant-specific program'to monitor the morphology of low S/N l indications present in the CR-3 OTSGs focusses' on plans for supplemental non-destructive' examination (s) (NDE) during future inspection outages. The purpose of this eddy current testing (ECT) is to gather additional data on i the areas within the TSCRN report where ECT can provide insights into '

behavior of the indication. This includes plans ~for random MRPC sampling i below the - TSCRN voltage threshold, as discussed in the response to RAI  ;

number 16. FPC's program also includes continued participation in the B&W~

Owner's Group (B&WOG) Steam Generator Tube Pull and Tube Integrity Programs. i Together, these programs provide an examination of a wide spectrum of damage i mechanisms utilizing both laboratory-grown and pulled tube -defects. The~  ;

purpose of the examinations is to expand the present level of knowledge on i the range- of mechanisms postulated to occur in OTSG tubing. Additional-discussion of these two programs has been provided in earlier FPC submittals as well as during periodic meetings between the B&WOG and NRC Staff.

There are no plans to pull additional tubes from the CR-3 steam generators.

The two tube pulls which have already been performed are considered to have provided the information necessary to adequately describe the currently active- degradation mechanisms. This is ~ not to say there will never be  :

another tube pull at CR-3. Another tube pull would certainly be considered if plant-specific operating experience indicates one is needed (as was done for this, the S/N, issue). .

The examination of the Oconee pulled tubes is nearing completion, with the results expected to be available some time during the first quarter of 1996.

While the tube pull placed priority on indications of special interest to ,

Oconee, the information with applicability to CR-3 has supported the  !

conclusions reached for the CR-3 pulled tubes. Once the final Oconee pulled tube report is issued, FPC will perform a detailed review of the entire report for the purposes of gathering and applying additional data pertinent to CR-3. Assuming the Oconee examination results are available during the first quarter of 1996, the NDE comparison study cited in the RAI is expected to be completed by September 1,1996.

2. Appendix B to Reference 3 discusses sizing of wear indications. Is a wear scar standard used at CR-3 for sizing these indications? If so, discuss the basis for applying the proposed voltage-based repair criteria to wear indications.

Appendix B to Reference 3 describes the nuclear industry experience with steam generator tube wear, including a discussion of both the rectangular (i.e., tapered) and the spheroidal wear scar geometries. The sizing discussion referred to by the RAI discussed both of these geometries. FPC's past use of wear standards at CR-3 can be discussed in similar terms.

FPC has historically followed a standard industry practice for the examination and evaluation of 0TSG Tube Support Plate Wear. This practice involves a bobbin coil examination for flaw detection and initial sizing.

Sizing is performed using standard phase analysis techniques employing calibration curves constructed from the ASME holes (for indications exhibiting a S/N ratio of greater than 5:1). This technique has been proven to be over-conservative for wear. Confirmatory sizing with the MRPC technic,ue is typically applied to those wear indications which are estimated to be greater than 40% through-wall by bobbin. This method of sizing the indication is more accurate and employs a voltage-based calibration curve constructed from the simulated wear scars in the calibration standard. The MP.PC also provides for characterizatior of the indications location, geometry, and morphology.

What FPC has termed volumetric wear (i.e., oval, circular) has only recently been confirmed in OTSG tubing. This was accomplished during the most recent CR-3 tube pull in Spring 1994. Prior to this time, the mechanism causing these indications at the TSPs was unknown. From an eddy current " signature" perspective, the volta tric wear cannot be differentiated from the pit-like IGA, even when examir with MRPC.

Once the mechanism producing the indications at the TSPs was confirmed, the 1994 tube pull examination results were focussed on the most appropriate NDE technique for addressing these indications. The criteria for assessing various ECT techniques were accuracy in detection and sizing. However, consistent with FPC's philosophy of allowing structurally sound tubes to remain in service, the optimum disposition strategy is one which, while removing defective tubes from service, does so without imposing overly-conservative repair criteria. Two disposition strategies were examined with these criteria in mind. The first involved applying historic percent thru-wall sizing criteria based on bobbin coil phase angle. Application of an alternate disposition strategy similar to that proposed for the IGA was the second strategy considered.

A review of the limited pulled tube data was conducted to confirm whether the bobbin coil phase angle technique for the low S/N ratio, oval wear was subject to the same thru-wall sizing variability as the IGA (Figure 3-1 of Reference 1). The inability to accurately size low volume IGA was one of the principal technical considerations which necessitated FPC develop an

e ,

j U. S. Nuclear Regulatory Commission 3F1295-03, Attachment 1 Page 3 alternate disposition strategy for the CR-3 steam generators. This review was inconclusive. While the sizing error for the volumetric wear was improved with respect to that of the IGA, this was based upon a database of just five (5) indications.

The depth of the volumetric wear, as measured by metallurgical exam, ranged from 14% to 35% TW, with a number of defects in the 30-35% TW range. When the bobbin coil voltage of the defects from the laboratory exams were compared with those in the field, it was apparent there were potentially a large portion of the wear indications in the OTSGs which approached the current Technical Specification limit of 40% TW (assuming voltage is proportional to volume, and hence, depth). None of the pulled tube ner scars appro:ched any Regulatory Guide 1.121 structural or leakage considerations. Based on this data, it was also apparent there was considerable conservatism in applying the 40% TW acceptance criteria to these indications. Thus, application of the percent through-wall criteria did not meet FPC's goal of keeping structurally sound tubes in service as well as the alternate dispositicn strategy did.

From an ECT analyst perspective, combining the volumetric wear with the IGA as part of a singular disposition strategy was preferable. As mentioned, indications attributable to the two mechanisms are indistinguishable when examined with NDE. Considering the two together also removed any liabilities associated with assuming all indications at the TSPs are atti;butable to wear. While this has been wholly supported by the pulled tube data, the amount of data is limited.

For the reasons given, the decision was made to cor,bine volumetric wear and IGA under the umbrella of a single disposition strategy. Further, since the metal loss associated with the wear mechanism is greater than that from the IGA, it was considered conservative to include the wear within the proposed approach, from an eddy current perspective. Once this decision was made, I the technical justification for the proposed strategy was revised to include con:ideration of data unique to both mechanisms. FPC would continue to disposition tapered wear using the standard industry practice described I above.

3. The proposed voltage-based repair criteria applies only to volumetric indications located outside the tubesheet regions. Describe the eddy-current inspection procedures and quantitative data analysis criteria to distinguish between volumetric and crack-like indications.

The eddy current inspection procedure used to distinguish volumetric from crack-like indications employs rotating probe technology. Indications reported from the bobbin coil probe examination are typically selected for rotating examination to further characterize their morphology. In lieu of examining all indications that cannot be quantified with the bobbin coil a sampling plan is implemented with the application of some established selection criteria for indications which can be logically grouped based upon

_ - - - _ - - - - - - I

U. S. Nuclear Regulatory Conwnission 3F1295-03, Attachment 1 e Page 4 signal response and/or location. If results from the sampling plan reveals crack-like flaws it then becomes prudent to examine all r.on-quantifiable indications with the rotating technique.

The specific rotating technique used at CR-3 has been the standard 3-coil probe which contains a 0.080 inch diameter shielded pancake coil, and two directed coils; one an axially wound coil, and the other a circumferential1y wound coil.

Each coil is located in the same axial plane of the probe and spaced around the probes' circumference at 120 degree intervals. Each coil is held in contact with the tubes inside surface by mechanical means while the probe is simultaneously rotated about its' major axis and traversed through the tube past the location of interest. This scanning method gathers inspection data l in a helical pattern and can be processed to display the relative orientation, position and dimensions of a flaw.

The pancake coil is sensitive to both volumetric and crack-like flaws and is used as the primary detection coil during data evaluation. The pancake coil is also employed for depth and dimensional sizing of indications. The axially wound coil is sensitive to volumetric and circumferentially oriented flaws and is used for characterization of flaw orientation. The circumferential1y wound coil is sensitive to volumetric and axially oriented flaws and is also used for characterization of flaw orientation.

The basic evaluation procedure used to distinguish between volumetric and crack-like indications is performed by comparing the response from the three inspection coils. These coils are calibrated by adjusting their individual gains to produce an equal response to a volumetric flaw such as a drilled hole or shallow wear scar in a calibration standard. The amplitude response from flaw indications can then be compared for the three coils applying the following logic. Volumetric flaws should produce a nearly equal signal amplitude response from each of the three inspection coils. Crack-like ,

flaws should produce an enhanced response of larger amplitude on one of the  !

two directed coils (axial or circumferential). Further evaluation of signal I formation and C-Scan mapping of ti.c data is employed to insure accurate disposition of the flaws morphology.

4. The eddy current signals generated by wear and IGA pitting may be significantly different due to the different morphologies for each type of degradation. The larger and more easily detectable signals from wear can bias the statistics for the IGA pits if they are used together. Discuss the potential bias from the use of both IGA and wear data in the correlations incorporating eddy current voltages.

Both volumetric wear and pit-like IGA are three-dimensional discontinuities with a spheroidal geometry. Eddy current bobbin coil signal amplitude or voltage is proportional to the removed metal volume within the coil field of view. This is the basis for establishing a correlation relating amplitude to

• Page5 volume. Volumetric wear will typically have a larger volume then pit-like IGA; thus sign.V amplitudes or voltages for wear will be larger while those for pit-like IGA will be smaller. The larger amplitude wear data will simply define the correlation curve at the upper voltage extreme whereas the smaller amplitude pit-like IGA data will define the correlation curve at the lower end. Voltage bias is not expected to be introduced by using a mixture of wear and pit-like IGA since the correlation is volume dependent.

Sianal-to-Noise

5. What actions have been taken to decrease the noise or increase the defect response signal during eddy-current inspections at CR-37 Discuss the use of alternate probes (size and type), inspection frequencies, assessments of noise origin, and other potential signal improvement measures. What alternative inspection techniques have been used in the past or been considered for the next inspection of 5/N indications?

Eddy current examination data has been scrutinized very closely in the past year in an attempt to identify noise sources that influence data quality.

These noise sources can be divided into three major areas which include,1) tube noise, 2) system noise and, 3) electrical interference.

1) Tube noise is either inherent due to the metallurgical and physical properties of the material or associative due to component configuration and operating environment. ,

A. Inherent tube noise comes from various sources such as non-alloying elements present in the material, surface condition, pilgering, geometry and thickness variations, and heat treat condition. Inherent i tube noise is seen by the eddy current field and produces signals which may interfere with the detection and/or sizing of indications.

Examples of inherent tube noise are pilgering noise, permeability variations, u-bend tangents, roll expansion transitions, and absolute drift from gradual thickness variations or heat treat. Probe wobble i is a dynamic noise variable caused by the modulation between the tube and the inspection probe and is usually factored in with tube noise.

Inherent tube noise and probe wobble are considered to be the primary contributors to the total background noise component.

B. Associative tube noise comes from various sources such as secondary side deposits and sludge, tube support plate and tubesheet interference, tube denting, residual stress and environmentally induced material property changes which are usually localized in a particular' area of the tubing.

2) System noise is a product of the inspection system configuration and includes the eddy current and associated control instruments, the cabling and inspection probes, and the remote manipulator and guide tube

.. , . - - ~ , . - _. . - . . - - .~ ~- - . . ~ - -.- .~ .

U. S. Nuclear Regulatory Comrmesion 3F1295-03, Attachment 1 Page 6 assembly.

3) Electrical interference is intrrduced into the signal path from various l sources such as electrical power supplies, poor grounding of the '

inspection system components, machinery and equipment operating nearby, and malfunctioning system components and probes.

There is very little that can be done to suppress inherent tube noise with the exception of permeability variations where magnetic biased probes are used with good results. Associative tube noise is handled  :

during data evaluation with the application of mixes and filters in an '

attempt to suppress the interference from known signal sources such as tube supports, tubesheets, roll transitions, copper deposits and dents.

The recent introduction of new or otherwise improved filtering techniques have also increased signal resolution through noise suppression.  ;

System noise has been reduced somewhat with the introduction of the Zetec MIZ-30 eddy current instrument, deemed quieter by some studies. The use of high performance or low-loss probe extension cables and improved connector designs have improved data quality. Efforts to reduce the length of analog signal cabling and the amount of connectors in the signal path are considered to be positive steps towards improving data quality.  ;

Electrical interference har been decreased through the use of dedicated power supplies, power 1 solation instruments and line conditioners. ,

Improved methods of grounding" system components and probes have shown some promise and the introduction of fiber optic lines for data transfer have provided immunity over those distances.

Another important aspect of the data quality issue is the emphasis placed  !

upon analyst training in the recognition of data quality. Structuring  ;

guidelines to address the issues involved with data quality and offering ,

example data .for training which presents the various types of noise  !

sources should improve the analysts understanding of how to handle or disposition various problems encountered with data quality.

There are a few ways in which to increase the inspection sensitivity; 1)

Increasing the probe diameter for bobbin inspection in an attempt to l increase the fill-factor and reduce probe wobble while also increasing the density of eddy currents in the material inspected, 2) Utilizing the features of the Zetec MIZ-30 instrument which allow for operator adjustment of the Variable Probe Drive and Programmable Gain options and,

3) Performing the initial data screening with -an inspection mode and frequency which is less affected by noise.

The probe diameter used is a compromise between maximum fill-factor and suce.essful probe delivery and probe life during an examination.

Typically, there is little to be gained in inspection sensitivity by increasing probe s;ze from the optimum diameter for examination to the i

U. S. Nuclear Regulatory Commission 3F1295-03, Attachment 1 Page 7 maximum achievable diameter.

There are two new features offered with the Zetec MIZ-30 that have been used to increase the overall inspection sensitivity. The Variable Probe ,

Drive feature provides the operator with the capability of choosing the drive voltage applied to the coil. Increasing the probe drive voltage will increase the amplitude of the analog signal without significantly increasing system noise. The Programable Gain feature provides the operator with the capability of choosing the degree of analog signal amplification prior to digitization of the data. Adjustment of the programable gain provides a compromise between signal resolution and signal saturation. System noise remains constant with increasing probe drive voltage and increases as the gain is increased.

Background noise includes tubing noise and system noise. This background noise is that seen by the data analyst and is that noise component factored into any signal to noise comparisons performed to address data quality concerns. Background noise is a factor of 15 times greater than the instrument noise alone. The noise component from the tubing, which is in the form of eddy current signals, increases with probe drive voltage and instrument gain.  !

All other sources that produce eddy current signals result in a linear increase in signal amplitude with increases in probe drive voltage and instrument gain.

Increasing the probe drive voltage and programable gain values will increase both the signal of interest and noise component amplitudes.

Therefore it is not expected that an increase in signal to noise ratios will be achieved. For the case of programable gain it is not expected that signal formation will be enhanced or that the formation of previously non-detectable indications (compared to data acquired at lower gain settings) will be produced. However, as the signal amplitude is increased, the physical size of an indication produced in the lissajous screen will increase and thereby make it easier for the analyst to visually detect and subsequently process the indication for evaluation.

The defect response can be increased by performing the initial data screening with an inspection mode and frequency which is less affected by noise. Typically, the differential test mode is less affected by tube noise than the absolute test mode and a frequency which offers increased depth of penetration while still remaining in the upper bounds of the probes frequency response curve is desirable. This practice is employed at CR-3 by utilizing the 400 kHz differential channel for initial data screening. CR-3 also employs a high frequency coil wrap for the bobbin probe which is tuned better for the 600 kHz frequency used for sizing and S/N calculations.

6. Appendix G to Reference 5 provided a simplified description of how noise is quantified. However, it is unclear how noise associated with an indication is measured when the signals are superimposed. Describe the procedures used at CR-3  ;

to quantify the signal-to-noise ratio of an indication where the contribution due  :

to noise is not easily separated from that of the indication. l The noise co;nponent is always superimposed on the signal component since the l noise cor,,onent is most always a continuous variable that is merely i fluctuating in intensity. Therefore the total voltage of the signal vector ,

of interest is factored against the voltage of noise vectors taken in the a immediate vicinity of the signal of interest using equal window openings. l In the event that the signal of interest contains unacceptable electrical interference it should be rejected and subsequently reexamined.  !

The procedure followed to quantify the signal to noise ratio is as follows:

1. Isolate the entire signal of interest by minimizing the lissajous trace window opening through adjustment of the associated cursor  ;

spacing. l

2. Measure the peak-to-peak voltage of the signal of interest and record  ;

this reading.

~

3. Using the window opening established in step 1 to determine the signal ,

of interest, move the data points to an area immediately adjacent to I the signal of interest which represents typical background noise.

4. Measure the peak-to-peak voltage of the noise and note this value.

5. In some instances it may be desirable to compare noise readings both immediately before and after the signal of interest in order to establish the deviation across the area of interest.

6. Calculate the signal to noise ratio by applying the formula; S/N.

Voltage of zthe signal of interest divided by the voltage of the noise component.

Figures I and 2 provide a pictorial illustration of how the S/N ratio is determined. The two Figures are bobbin coil graphics of an indication  ;

located in 1992 CR-3 pulled tube 41-44, section 2. This tube section corresponded to the first span of the 'B' OTSG and the indication illustrated was confirmed to be pit-like IGA by destructive examination.

From Figure 1, the indication exhibited a bobbin coil signal amplitude of 0.90 volts. Figure 2 illustrates Steps 3 and 4 above, determining a peak-  !

to-peak voltage value of 0.31 volts attributable to noise. Using figures 1 I and 2 in conjunction with one another, a S/N ratio of 3:1 is calculated (0.90V/0.31V) for this indication. j

7. Appendix A of Reference 2-lists the eddy current voltage amplitude for all identified S/N indications in the CR-3 steam generators. However, the table does '

not include quantitative data for the level of noise measured for each indication. Provide the data recorded during eddy current inspections quantifying the level of noise associated with each indication. For indications inspected in more than one outage, provide noise measurements recorded during each inspection.

The level of noise associated with each S/N indication in the CR-3 steam generators has not been recorded in a readily available format during past inspections. The information exists in the raw eddy current examination data and would require a manual re-analysis of the subject tubes in order to measure and record the noise components associated with these indications.

8. The last paragraph in Section 2.3.1.3 in Reference 3 states that "the 0.540 inch HF bobbin coil exhibited slightly better detection performance than the 0.510 inch HF bobbin coil." This section also indicated that the 0.540-inch high frequency bobbin coil gave cleaner (higher signal-to-noise ratio) and more  ;

repeatable data. Do you plan to use the 0.540 inch high frequency bobbin coil  ;

probe for upcoming inspections of CR-3 steam generator tubes? If you plan on i using a bobbin coil probe with a diameter other than 0.540 inches discuss your t basis for doing so in light of the above.

There are no plans to use the 0.540 inch diameter bobbin probe at CR-3 in i future inspections. The 0.510 inch diameter bobbin probe is the standard l probe size used for inspection of OTSG tubing and it is expected that the ,

resolution gained from the application of the 0.540 inch diameter bobbin t probe would be negligible.

There would also be difficulties encountered with the introduction of the 0.540 inch diameter bobbin probe in a production examination. It is expected that there would be difficulty delivering the probe through the full length of the tubing due to restrictions caused by dings and tube end damage. There is the possibility of stuck probes which could cause problems with probe retrieval and shorter probe life due to increased friction between the probe and tube.

9. If all indications are recorded regardless of voltage amplitude and the i growth mechanism is dormant, only a small number of new indications should be detected during any outage (i.e., small voltage indications at the threshold of detection). What steps has the licensee taken to address the root cause for indications which have faded in and out from inspection to inspection?

The root cause for certain indications fading in and out from one inspection  !

to the next is believed to be related to the small amplitude (and therefore, volume since the two are proportional) of the indications exhibiting this behavior and the detection limitations associated with this size indication.

Since there is nothing which can be done to change the size of the j

_- \

-l l

U. S. Nuclear Regulatory Commission 3F1295-o3, Attachment 1  ;

Page la discontinuity, the steps - taken to address this phenomena are related to  !

improvements in the NDE area. This is discussed in the responses to RAI. l

' question 5. In: addition, eddy current data analyst guidelines require the ,

analysts to address previous history for each tube in which an indication is i called. TI-ls helps maintain database integrity by ensuring the analyst ,

takes a'secoed look at locations with previously reported indications. j I

In order to evaluate the frequency of this " fade" phenomena occurring, a j review of previous ECT data was performed. The review started with the 1987.  ;

inservice examination results and . worked towards the latest (1994)  :

inspection, looking for S/N indications which were considered present during at least.two outages, but which were not detected during each inspection of i the. tube containing the indication. The results of this review show that .

i this does occur, but the occurrence is a limited scope (< 5%).  ;

Given the results of the evaluation, a compensatory factor considered in i this issue of indications fading in and out is that the indications most  !

subject to this occurring are also those of the least structural  !

significance. A review of operating history shows the bobbin voltage of I these indications to be typically well below the minimum voltage threshold ,

(0.9 volts) established within the TSCRN. Thus, although these indications  !

may not be detected during each and every outage, the significance of  ;

missing an indication during an outage is minimal due the impact of these indications (assuming they are all representative of actual degradation) on the structural integrity of the tubing.

10. New 5/Ns are defined as those that have voltages greater than 0.9 volts and that have not been identified in any outage since 1987. Discuss the basis for considering only indications identified during inspections since 1987 in light of the fact that some. indications were first identified many years earlier.

The establishment of a cut-off date, before which indications are assumed E9.1. to have been present, is considered a conservative approach to defining new (S/N) indications. Rather than review original eddy current data tapes.

to determine whether an indication was present prior to the proposed cut-off date, the proposed approach considers any indication not currently in the database to be "new", and requires an initial MRPC inspection be performed for those indications exhibiting a signal amplitude greater than 0.9 volts.

The specific year (1987) was chosen based upon limitations of available historic ECT data. The eddy current test data management system used at CR-3 only contains previous tube history for inspections performed since 1987.

Prior to this time, the analysis techniques and analyst guidelines were such that the results of the earlier inspections could not be readily compared with the results of an inspection today.

FPC has inspected 100% of the CR-3 steam generator tubing at least one time since 1987. In recent inspections, it has been FPC's practice to inspect tubes containing previously identified indications, at each subsequent

U. S. Nuclear Regulatory Commission 3F1295-03, Attachment 1 Page 13 inspection. Thus, there is a high confidence that the large majority of S/N l indications present in the CR-3 OTSGs have been previously identified and are contained in the current ECT database. This would naturally include valid signals present prior to 1987. l l

Growth

11. Appendix B of Appendix A to Reference 5 assessed the growth of intergranular j attack (IGA) patches for three tubes examined in 1989, 1990, and 1992 outages. l The study concluded that there was no evidence of growth of the observed IGA j patches included in the study. While past growth assessments may support your i assua:ption of zero growth for IGA S/N indications, the basis for assuming no  !

growth for tube wear indications is unclear. Provide the basis for this '

assumption. l The 1994 growth rate study performed by Packer Engineering (provided as part of the response to RAI #35) included consideration of CR-3 inservice S/N indications located at support locations. Based upon the 1994 CR-3 tube pull results, the indications present at the support plates can be attributed to wear. Thus, the results of the latest growth rate study support a conclusion that there is essentially no growth of wear indications ,

within the CR-3 OTSGs. This conclusion is based upon a review of the entire  ;

population of indications. Refer to Section 4.4 of Reference 1 for a more detailed discussion of the results of this study.

The B&W growth rate study also included a limited number of data points on defects located at tube support plates, but the data did not support a growth rate analysis of these indications (small number of data points, significant neaative mean change in bobbin voltage associated with the indications, etc.).

12. How frequently will each S/N indication be inspected in future outages?

FPC presently plans to inspect all S/N indications during each future inservice NDE inspection. However, future NDE inspection results providing information on degradation growth rate will be evaluated for justification of a statistically-based sampling plan of these tubes which would allow for less than a 100% inspection.

13. A number of growth studies have been cited in the various submittals supporting this TS amendment. Discuss how differences in probes, calibration procedures, cable lengths, calibration standards (including the use of transfer standards), probe wear, and other related factors have been accounted for in each of these studies. Indicate whether the data used in each of the studies are based on Vmax voltages or peak-to-peak voltages. It would be sufficient to address the more recent outages since they most likely used similar techniques and analysis criteria.

The three growth studies specifically referenced within the TSCRN 203 ,

technical report were performed independent of one another. In fact, steps  ;

were taken to maintain the independence of the various studies. This meant allowing the individual organizations - EPRI, B&W, and Packer, - the latitude to utilize the technical procedure they deemed appropriate and not dictating any one single approach to the evaluation. Thus, the procedures and data used in the individual studies are not necessarily consistent, even though the results and conclusion of "little or no growth" are. Each study  ;

is summarized sepatately below.

The EPRI growth rate study utilized eddy current bobbin coil voltages obtained from the Refuel 8 pulled tubes which were field inspected during  :

the 1989, 1990, and 1992 CR-3 inspection outages. Peak-to-peak voltages i were used in the evaluation, with the 600 kHz channel chosen for comparison.

To compare three successive outage data acquired by different diameter size probes and varying lengths of extension cable, eddy current signals from a 100% TW calibration hole were normalized to 5 volts peak-to-peak at a phase l angle of 40 degrees.

The B&W study utilized eddy current bobbin coil voltages from the 1989, 1990, and 1992 CR-3 Outages. Indications which were inspected in at least two of the outages were compared against one another using the bobbin coil technique. Peak-to-peak voltages were utilized in the evaluation, in order 4 to account for the changes to the essential variables which took place over i the period of time covering the three Outages. The essential variables of this technique are probe type and operating range examination frequencies, data acquisition speed and calibration standards. Each of these variables  !

was evaluated as were the differences in data analysis guidelines during 1 this time. The following is a brief discussion of the variables considered and their treatment.

The 1989 and 1990 examinations were performed with a mid-range frequency bobbin probe operating at 600, 400, 200 and 35 kHz in both differential and absolute modes. The 1989 target probe speed was 14 inches per second i coupled with a data sampling rate of 400 points per second, yielding i recorded results of 28.6 data points per inch of tube examined. The 1990 target probe speed was 24 inches per second coupled with a data sampling rate of 800 points per second yielding recorded results of 33.3 data points ,

per inch of tube examined. The 1992 examination was performed with a high- I frequency bobbin probe operating at 600, 400, 200, and 35 kHz in both the differential and absolute rrodes. The target probe speed and data sample

3F129543, Attachment 1 Page 15 rate were the.same as during the 1990 exam. While the slight differences in f recording rates could result in some variation in sizing, the variation is considered acceptable .since calibration curves are fit with standard reflectors acquired at the same speed. 1 The change in probe operating range, from a mid-range to high frequency ,

design, was considered. For the probe and frequency combinations used during

~

the three outages, flaw detection is equivalent and was performed each time  !

with the 400 kHz differential channel which operates nearly equivalent for  :

both probe types. Flaw sizing, however, should be more accurate during the  !

1992 exam which used the high frequency probe and evaluation of 600 kHz.

This frequency is closer to the optimum test frequency for OTSG tubing and provides better phase separation for flaws of varying depths. l The calibration standards used for the~ three examinations were different.

However, they were of similar style with equal volume and depth of-artificial f1?ws and were therefore considered' equivalent for the purposes  ;

of the comparison. ,

Analyst guidelines also varied somewhat between examinations. Two changes  ;

merit further discussion. The first deals with the frequency used for reporting indications. During the 1989 and 1990 exams, indications were '

reported with the 400 kHz differential channel when they occurred in the freespan of the tubing. A 400/200 kHz mix channel was used for indications i at support intersections. During the 1992 examination, freespan indications  :

were reported with the 600 kHz differential while support locations were  ;

reported with the 600/200 mix. Since these two frequencies offer  ;

differences in phase spread, with the 400 kHz being smaller, the calibration l curves represented by these two channels diselay different degrees of 1 resolution. l The second point of interest is the method used for voltage normalization. l During the analysis setup it is common practice to set a specific voltage on  !

a particular signal from the calibration standard and then "save" this voltage scale to the other data channels. By performing this voltage normalization, a common scale can be applied to all the data. During the l 1989 and 1990 outages, the 400 kHz channel was set to 4 volts peak-to-peak '

on the signal from the broached TSP. In 1992, the 600 kHz was set to 6 volts

. peak-to-peak on the signal from the 4-100% drill holes. Although both '

procedures return a similar voltage scale, a different procedure was used to  !

allow comparison of the data. Using the 400 kHz, the system was set at 4  :

volts peak-to-peak on the signal from the 4-20% . flat bottom holes. -

Indications from all three outages were sized with the identical, identified technique and compared.

The Packer growth ratc study utilized eddy current bobbin coil voltages  ;

obtained during the >92 and 1994 CR-3 inspection outages. The study also i utilized peak-to-peak vcitage values. The essential variables of the 1992 '

and 1994 outages were maintained the same in order to facilitate th' comparison.  ;

14. Has a growth rate study of S/N indications been performed based on rotating pancake coil (RPC) sizes (i.e., axial and circumferential length)? If so, provide the results. If not, discuss the usefulness of such a study.

A comparison of axial and circumferential extent was performed for those indications of interest which received an MRPC inspection (clip plot sizing) during both the 1992 and 1994 inspections. The study was somewhat limited .

due to the number of indications (33) which met the aforementioned criteria.

The mean change in axial and circumferential extents were 0.008 inches and

(-) 0.015 inches, respectively. The standard deviation of all changes in extent measurement is 0.047 inches.

The resu'ts of this evaluation are generally consistent with those obtained by bobbin coil voltage for the various growth rate studies. Procedures for clip plot sizing were essentially unchanged during the two inspections, although there is likely some amount of analyst variability between the two measurement data sets. This variability is enveloped / bounded by the conservatism demonstrated for the MRPC sizing technique. .

15. An S/N indication is considered to have grown if it exhibits a 0.5 volt increase from the previous inspection and has a measured voltage in excess of 0.9 i volts. The basis for the 0.5 volt increase resides in the fact that this ,

criterion was used in the previous inspections of S/N indications. Provide technical justification for not performing a subsequent RPC examination of 3 indications previously RPC examined unless the bobbin voltage increases by 0.5 ,

volts. If an indication was identified as having an eddy current response of 0.4 volts and was later reexamined and found to exhibit a 0.8 volt response, discuss why this indication is not considered to have grown. The staff notes that since 1 the degradation mechanism is considered dormant and no allowance for flaw growth was used in the development of the tube repair criteria, there should be essentially no change in voltage with the exception of variations arising from nondestructive examination uncertainty. Since the probe wear model and analyst variability model being proposed have a total uncertainty of approximately 24%

at an upper 95% confidence level, it seems like a much lower threshold than 0.5  ;

volts should be used. Please discuss. Is the 0.5 volt increase determined from  !

the most recent inspection of the indication or from the original inspection in  ;

which the indication was identified? .

Voltage changes and their relationship to growth are discussed using data sets from CR-3 steam generator B; results using data from steam generator A are comparable.

. Free-span indications attributed to pit-like IGA l

Figure 3 shows a scatter plot of measured voltages for freespan indications from two consecutive outages attributed to pit-like IGA from CR-3 steam generator B. The measured voltages are essentially uniformly distributed about the zero growth line at 45 degrees indicative of no overall change. This observation is also supported by data presented in Figure 4 and Figure 5 which show amplitude change in volts and percentage respectively. Scatter plot and histogram formats are used in both figures to show changes. Voltage change was determined by taking the difference between the 1994 and 1992 data; percentage change was determined by dividing the voltage change by the average of the 1992 and 1994 measured voltages.

The data in Figure 4 shows that the mean voltage change is +0.0015 volts i (essentially no change) with a standard deviation of 0.105 volts. In terms of percentage change, the Figurs 5 data shows that the mean percentage change is -0.46% with a standard deviation of 18.41%. Since the data essentially show a near-zero mean in voltage or percentage change, no strong evidence of growth exists.

Indications at Tube Support Plates attributed to wear figure 6 shows a scatter plot of measured voltages for indications from two consecutive outages attributed to wear at tube support plates from CR-3 steam generator B. As before, the measured voltages are essentially uniformly distributed about the zero growth line at 45 degrees indicative of no overall change or growth. This observation is also supported by data presented in Figure 7 and Figure 8 which show amplitude change in volts and percentage respectively. Scatter plot and histogram formats are used in both figures to show changes. Voltage change was determined by taking the difference between the 1994 and 1992 data; percentage change was determined by dividing the voltage change by the average of the 1992 and 1994 measured voltages.

The data in Figure 7 shows that the mean voltage change is +0.012 volts (essentially no change) with a standard deviation of 0.165 volts. In terms of percentage change, the Figure 8 data shows that the mean percentage change is +0.83% with a standard deviation of 24.6%. Since the data essentially show a near-zero mean in voltage or percentage change, no strong group evidence for growth exists. However, a few individual data points exceeding a + 0.5 volt change likely show evidence for small growth.

U. S. Nuclear Regulatory Commession 3F1296-o3, Attachment 1 Page 24 The 1992 and 1994 data were acquired using the same acquisition procedure, using many different probes, with the data analyzed by numerous analysts.

The observed scatter in the data simply reflects overall NDE repeatability or NDE system measurement error. The scatter in the tube support plate wear data is greater because of the effects of support plate mix residual.

This mix residual acts like a noise vector which perturbs the indication increasing the scatter associated with the measurement of its features, e.g., magnitude and phase angle.

The 0.5 volt threshold originally proposed for establishing change essentially bounds all of the data for pit-like IGA (Figure 4(a)), and most of the data for wear at tube support plates (Figure 7(a)). However, with a two-sigma NDE system repeatability error of 0.21 volts for free-span IGA, a more-conservative threshold of 0.25 volts for growth could be-utilized. This increase would be applied using the most recent inspection data.

Essentially, the difference in the 0.25 and 0.5 volts is attributable to the manner in which each was developed. The 0.5 volt value was derived based upon technical judgement and was a criteria which was intended to provide, with some assurance, that growth was occurring. The 0.25 volt value is believed to represent the other end of the spectrum. It is representative of an approach whereby, with some assurance, the earliest signs of growth would be detected. Both approaches have benefits and drawbacks. However, based upon the data included within Figures 3 through 8, it appears both criteria are appropriate for their intended purpose.

In the context of a percentage change .in voltage, the absolute voltage level needs _ to be considered as shown with the data in Figure 5. For amplitudes less than approximately 0.9 volts, the percentage change can be quite large with extremes on the order of 100%. For amplitudes greater than approximately 0.9 volts, a 25 percentage point change bounds the bulk of the data. Clearly, estimates of the NDE system error will be strongly influenced by the voltage ranges of the indications included within the data set and the effects of support plate mix residual. For free-span indications with voltages greater than 0.9 volts, the 24% NDE system measurement error originally estimated agrees reasonably well with the experimental data.

Leakaae 16._ The basis for the 0.9 volt cutoff for determining when RPC examinations should be performed and the length based limits applied is net clear in light of past inspection data which indicates that voltages of about 0.8 volts can have an axial extent in excess of 0.5 inches (Figure 28 in Reference 5). Has a systematic review of all available CR-3 data as well as any pulled tube data from other plants been performed which supports the assumption that the 0.9 volt

. criteria will ensure that the proposed dimensional limits will not be exceeded?

U. S. Nuclear Regulatory Corrmesion 3F1295-03, Attachment 1 i Page 25 Since the 0.9 volt cutoff is presumably based on experience to date, discuss your plans for randon RPC sampling below the appropriate voltage threshold (0.9 volts is being proposed).

A systematic review of all CR-3 data has been performed and the results of this review are presented in the technical report which supports the proposed TSCRN (Reference 1).

Inclusion of the particular indication mentioned in the RAI within Figure 28 of Reference 5 was an error. This indication, from RCSG-1B, tube number 70-125 had measured axial and circumferential extents of 0.52 and 0.19 inches, respectively, and is attributed to tapered wear. S'.nce tapered wear is not included within the scope of the proposed TSCRN, it ,

should not have been included within the subject data set. l Other plant data has always been considered for applicability and incorporation into the CR-3 database. Reference 5 included a discussion ,

of some IGA data from the Palisades nuclear plant. Further, industry data i used to support Degradation Specific Management efforts has been reviewed throughout the development of the CR-3 disposition strategy technical basis. This data has been utilized where appropriate.

The RAI requests FPC discuss its' plans for random MRPC sampling of indications exhibiting a bobbin coil voltage below the proposed lower voltage cutoff. Presumably, this is proposed as a means of using field data to validate the continued applicability of the voltage cutoff, as was addressed by Confirmatory Action Letter No. 2-94-004, Item # 4 (Reference 8). At the time the CAL was written, the cutoff value was based on a limited database, making the focussed inspection an appropriate action.

However, as discussed in the TSCRN 203 topical report, 413 additional data points were added to the database as a result of the 9R MRPC special interest inspection. Given the current amount of data, there is no reason to require additional MRPC for purposes of validating the voltage cutoff.

Although not a commitment, FPC does intend to inspect these indications on a time and resource basis during future inspection outages in order to further our understanding of the condition of the CR-3 OTSGs.

17. Independent staff calculations determined that leakage integrity is not assured at a 95% confidence level for indications with a bobbin coil signal of 0.9 volts. Discuss the 0.9 volt lower limit in light of this staff finding.

Consider the response to Question 18 below.

FPC calculational results do not agree with the NRC Staff's. For a bobbin coil signal of 0.9 volts, the volume and depth are estimated using Figureg 9 and Figure 12. From Figure 12, the volume is estimated at 90 x 10- in 4 at the upper 95% prediction interval. Using Figure 9, this volume corresponds to a depth of 80% through-wall at the upper 95% prediction interval. Since this depth is less than 87% through-wall, leakage integrity is maintained.  ;

18. .. The data in Figures 5-1 through 5-5 in Reference 1 illustrates the relationship between eddy current voltage measurements and the dimensions of S/N indications. However, these relationships are based on nominal correlations *

prediction intervals. for each of these figures ansi deterr.ine the volume and ,

evaluated at the 95% prediction interval. ,

95% prediction intervals for data presented as Figure 5-1 through 5-5 in '

(Reference 1) are shown as Figures 9 through 13 herein. Linear scaling of the prediction interval plots as opposed to log-log plots of the original data is used because of software limitations. In addition, for Figure 11, i volume has been correlated with the circumferential extent in afis rather -

than inches as originally presented in order to be consistent with the axial length correlation. j The 95% prediction intervals shown in the figures are calculated using the j equation  :

Yo - (a+bXo ) +/- t o,25 *s where a and b are the intercept and slope respectively of the least squares fit to the experimental data, s is the residual variance, and t o.25 is the Student t-parameter (Reference 9).

Dimensional values calculated in response to specific questions were estimated using the exact equation.

The volume and corresponding bobbin coil voltage associated with an 87%

through-wall indication is estimated as follows. From Figure 9, the volung aspociated with an 87% through-wall indication is approximately 104 x 10~

in at the upper 95% prediction interval. Figure 12 is used to estimate the corresponding bobbin coil voltage; entering the upper prediction interval at the desired. volume gives an amplitude of approximately 1 volt which exceeds the proposed 0.9 volt bobbin coil screening limit.

The conservatism present in the ligament calculation supported using raw data without consideration of the prediction interval. The calculations are based upon tube burst test results where the length of the degradation was one to two inches in length. Volumetric degradation with an axial '

extent less than the proposed limit of 0.33 inches would represent a much less severe degraded condition. Hence, the depth limit to avoid leakage is conservative. It is expected that the maximum depth of pit-like IGA, which is within the proposed axial and circumferential extent limits, would have to be virtually through-wall to result in leakage during a postulated steam line break.

19. Clarify what material properties were used to determine the proposed dimensional limits. Reference 7 indicates that the " probable" values are the 95%

probability /95% confidence values as does page 4-1 of Reference 1. However, the calculations provided in the appendices to Reference 7 indicate both " actual" and

" average" values were considered.

The determination of the proposed dimensional limits utilized the

" probable" tubing material properties (i.e., established at a 95%

probability of occurrence at a 95% confidence level) as an input to the calculation.

20. In Reference 5 (Section 8.2), a correction was made to account for the lower voltage response when using the mix frequency channel for sizing tube support plate indications. Is a similar correction needed with the current approach?

Discuss how the proposed depth / volume / bobbin voltage approach accounts for the lower voltages from indications located at the tube support plate intersections.

Also, discuss the basis for combining the data from tube support plate and freespan indications given that the voltages may not be comparable.

Freespan indications associated with pit-like IGA are typically reported using Channel 1 (600 Khz) whereas volumetric wear indications at tube

support plates are reported using a Mix 1 analysis channel. The voltage j scales for the two analysis channels e.g., 600 Khz and Mix 1, are l established differently using current Crystal River 3 analysis guidelines.

I In order to establish a volume-voltage correlation curve for both pit-like l

IGA and wear, eddy current indications were reanalyzed with the Mix 1 voltage scale set in the same manner as Channel 1. Measured signal amplitudes could then be plotted on the same curve relating volume to voltage.

The original voltages from wear scar indications are smaller because the voltage scale for the Mix 1 analysis channel had been set differently from ,

that of Channel 1 (600 Khz). If the voltage scales for the two analysis channels are initially set in the same manner then voltage readings from both channels are comparable.

21. The proposed dimensional requirements do not specify limits for indications exhibiting geometries with the maximum linear dimension inclined at an intermediate angle with respect to the steam generator tube axis (i.e., neither axial nor circumferential). Staff calculations indicate that consideration of only defect axial or circumferential lengths may be nonconservative for certain defect geometries. Discuss how the proposed dimensional limits will be applied to an S/N indication with its major axis not alignej to either the tube axial or circumferential directions.

FPC calculational results do not agree with the Staff's. The orientation terminology of the proposed dimensional repair criteria as ' axial' and

'circumferential' relates to the limiting Regulatory Guide 1.121 structural analysis and not the actual implementation of the criteria.

The analysis which calculated the proposed limits (Reference 7) assumed a planar defect, with no credit taken for ligaments between micro cracks.

A crack-like defect oriented strictly in the axial or circumferential l plane is bounded by this analysis. Other possible defect configurations which could occur in the secondary side of the CR-3 OTSG tubing are also covered by the structural analysis.

The configuration of the defect can be either symmetrical or non-symmetrical about the tube axis because the primary strm of concern (axial stress due to differential expansion effects during a LOCA) are not affected by the asymmetry of the defects. As indicated in the calculation, .all pertinent loads are reacted by either the tube or its support without the need for any bending moment capability of the tube at the defect (i.e., a plastic hinge can be assumed at the defect).

The projected axial and circumferential dimensions of an indication at an intermediate angle to the tube axis provide a good description of length needed to evaluate the structural integrity of a degraded tube. Test data on tubes with volumetric defects and plastic collapse considerations support the above statement.

22. Reference 1 provided limited details of the testing performed to support the nondestructive examination uncertainty allowance of 13.05% (pg 3-17). Discuss how many analysts were used, clarify if 10 different probes were used, discuss the need for considering additional data since the study was based on an examination of only six indications. Discuss the similarities and differences in the morphology between the indications in the NDE study and those in the population of S/N indications examined from pulled tubes at CR-37 The purpose of the test was to investigate data acquisition repeatability.

Three different probes were used including a conventional 510 bobbin probe and two variations of a 540 bobbin probe, e.g., mid-range and high-  ;

While the absolute probe sizes and inspection frequencies are different one must take into account differences in tube wall thickness and tube diameter.

The field procedure used for length sizing S/N's and the procedure used to support the length sizing uncertainty error are the same.

l

U. S. Nuclear Regulatory Commission 3

3F1295-03, Attachment 1 Page 37 The procedure used for length sizing S/N's at CR-3 differs from that procedure used in the EPRI report NP-6864-L. The CR-3 procedure makes use of a routine in the Zetec Eddynet software called MEASFLAW or measure flaw while the EPRI report niakes use of a routine in the Zetec Eddynet software called CRKMAP or crack map.

The MEASFLAW routine is more applicable to volumetric indications since it allows measurement of a flaws axial and circumferential extents or length and width. The CRKMAP feature is used more for crack-like indications at the top-of-tubesheet since it calculates a flaws length for its major dimension and provides information about the flaws position with respect to the top-of-tubesheet. Both methods apply similar operator input and calibration such as axial and circumferential scale adjustment, threshold adjustment, selection of coil and frequency used for measurement, and both make ,

use of rotating coil data acquired following the same procedure. It l 1s expected that the resolution of the two measurement methods are .

comparable.

25. In order to demonstrate RPC sizing capability for S/N ir.dications, CR-3 pulled tube data were combined with data from IGA samples obtained from the B&W Owners Group NDE Committee. Discuss the applicability of combining eddy current data obtained from these two sources. Consider the differences in voltage response for the laboratory grown flaws and the sulfur-induced IGA indications found at CR-3.

Dimensional sizing error is not dependent on signal voltage and voltage  !

scales established during eddy current testing are arbitrary. A key factor contributing to sizing error is the length of the discontinuity in ,

relationship to the average coil diameter. For situations where this ratio l 1s small, the absolute error can be large but is always conservative. For i small discontinuities, e.g., those with dimensions comparable to or 1 smaller than the average coil diameter, one is essentially measuring the coil field spread or profile which is larger than the discontinuity. This ,

is why the measurement error is always conservative. l l

Combining dimensional sizing data from CR-3 pulled tube pit-like IGA and lab samples was done to establish the error at two length extremes. The lab samples have dimensions large relative to the average coil diameter  ;

whereas the pit samples have dimensions much smaller that the average coil l diameter. The fact that different voltage ranges are included is immaterial.

26. In Reference 3 it is stated that the probability of detection (P00) for the RPC was somewhat less than for the bobbin coil (page 1-2). This is supported by Section 3.2 of Reference 6; however, the study documented in Appendix B of Reference 6 (i.e., page B-4 of Appendix B to Reference 6) states that the IGA patches were better detected with the RPC. Please clarify these observations.

The exact basis behind each of these conflicting statements was not retrievable. Reviewing the technical data presented with the discussion of each study indicates both statements / conclusions to be supportable with the data provided. Section 3.2 referred to Figures 3-4 and 3-5 within the same text. From this data, one could conclude bobbin showed slightly better detectability. The data immediately preceding the relative POD comparison of the two techniques in Appendix B indicates a larger percentage of the total number of defects were detected with MRPC. Again, dependent upon the criteria used within the individual study, it is possible to reach the same conclusion as the text. Based upon the recent re-review of the data, the POD for the two techniques is' considered comparable in the defect range of interest.

27. What is the general shape of the free-span IGA? For example, is the shape  ;

cone-like or similar to a flat-bottomed hole? ,

The free-span IGA is three dimensional, generally appearing to be the i shape of a half-ellipsoid or as a " thumbnail-shaped" patch. The deepest i part of the defect generally occurs at the mid-plane of the defect. l l

Other Issues  ;

28. It is not apparent from the data presented, what data were used in t.he various correlations. The staff is having difficulty comparing the results from -

one section of a report to another and from one report to another. In addition, it appears that some correlations have more data than others although they should ,

apparently be coming from the same database. For example, the number of data I points used in Table 3-2 of Reference 6 does not match the number of dr.ta points used in Appendix D to Attachment 2 of Reference 4. Another example is tie number  :

The information requested by this RAI question is included as Appendix A  ;

to this text.  !

Two general comments are provided with respect to this request. The last sentence in item 'a' appears to be out of context with respect to the balance of the request. It addresses plans for the upcoming outage NDE inspection while the majority of the request deals with providing pulled tube data. For completeness, a response is provided. As discussed in earlier RAI responses, there are no plans to change the probe of record for the upcoming outage from the ones (bobbin coil or MRPC) utilized i during the last two CR-3 outages. l The second comment deals with the scope of the request associated with item 'b' above. As written, the request could be interpreted to include i the data for every correlation which has ever been provided to the NRC l relative to the CR-3 OTSG S/N issue. FPC has chosen to address this i request in a much narrower fashion. Much of the older (1992) work has been superseded by more recent efforts as additional tube pull and inspection data has become available. NRC Staff review shoulu focus on the cost current, up-to-date information available. To this end, Appendix A provides the following information as part of the response to RAI number l 28, sub-item 'b' l

1) The data supporting all correlations included as part of Technical i Specification Change Request Number 203 (Reference 1).  !

2) The data supporting the probability of detection (P0D) correlations included as part of the final CR-3 9R tube pull examination report (Reference 3).

3) A discussion of the reason for the two differences cited within RAI number 28.

Additional information on other specific correlations can be made available upon request. Unless noted with the 'A ' prefix, page numbers are same as original document.

29. On page 2-5 of Reference 3, it indicates that a small amplitude low S/N indication was observed in the field for the 75% through-wall defect in the lower tubesheet region of tube 68-46; however, in other portions of Reference 3 (e.g.,

Table 2-3, page 1-4) it appears that the indication was not identified in the field (i.e., called an NDD). Please clarify whether this indication was detected in the field or not. If hindsight was used to identify this indication, discuss any improvements made to the eddy current data analysis guidelines to prevent missing such indications in the future. What is the threshold for reporting S/N indications during eddy current inspections?

The indication in the lower tubesheet region of tube 68-46 was not reported during the field examination. Hindsight was used to identify this indication following destructive examination. This flaw does not produce an indication with the bobbin coil technique which is reportable as a flaw hence no changes were made to the andysis guidelines to prevent missing such an indication in the future.

There is no minimum voltage threshold for reporting S/N indications during eddy current inspections at CR-3.

30. 600 kHz is stated to be the best frequency for sizing S/N indications but correlations of through-wall depth to voltage (Vmax) were developed at 400 kHz (Section 7.1 of Reference 5) justifying a 2.7 volt limit corresponding to a 100%

through-wall flaw. Staff calculations using the data in Table B2 of Appendix D to Reference 5 indicate that a reduction in the voltage limit corresponding to a 100% through-wall flaw from approximately 2.7 volts to 2.2 volts is obtained when using the 600 kHz channel (presumably the channel used to size indications in the field). The staff notes that the licensee is not currently proposing this correlation. Discuss the calibration procedure used in the development of Table B2. Discuss whether the voltages measured and recorded in the field are peak-to-peak voltages or Vmax. If peak-to-peak voltages are recorded in the field, provide a correlation based on peak-to-peak voltages developed with the frequency used to size these indications. These correlations should use all of the data (not just the 10 data points to support the 2.7 volt limit).

Voltages measured in the field are peak-to-peak voltages. Table B2 of Appendix D to Reference 5 utilized V y readings. The data presented in the Table was not used in the correlafion because of the difference in the way the voltage scales are set.

31. Discuss how the burst pressure of specimen 68-46-3A was adjusted to account I i for the brass shim. If discussed in the Electric Power Research Institute (EPRI) i Burst Testing Guidelines (Reference 2 of Reference 3), submitting a copy per  !

Question 35 below is acceptable.

The method of adjusting the burst pressure of 68-46-3A for the presence of ,

the brass shim is discussed in the EPRI Guidelines for Burst Testing Steam  !

Generator Tubes. The guidelines document is provided, as requested, in ,

response to question number 35 of this RAI. l

32. Quantify the level of error associated with the estimation of defect volume  !

from a metallographic analysis. )

The metallographic examination of a tube providu the best estimate of the 4

volume of a degradation, and is usually considered to be the real or actual volume. This estimate is normally obtained by measuring the

'; maximum axial and circumferential extents of the degradation from an ,

enlarged planar view, and measuring the depth from an enlarged sectional '

view through the maximum width of the degradation. For volumetric degradations, the volume is assumed to be half of an ellipsoid, which is a constant times the product of the three semi-axes defined by the three  ;

measured dimensions. '

The ellipsoid assumption presumes that the planar view of the degradation is described by an ellipse, and the section view is described by half of another ellipse, neglecting the curvature of the tube. If the outline of l the cavity is irregular the use of maximum extents will yield a somewhat 1 non-conservative volume. Volumetric degradations generally have the shape  ;

of a shallow dish, with deepest penetration at the center, which makes the i assumption of an ellipsoid shape most appropriate.

1 It is estimated that the measured depth and axial and circumferential extents of the cavity may each vary from the true dimensions within a j range of 3plus or minus 0.002 inches. For degradation on the order of 210 l x 10-6 in , which correlates to a 3.6 volt NDE limit for leakage discussed I in Section 5.2.2 of Reference 1, a 0.002 inch error amounts to an l approximate i 4% error in calculated volume. l

33. On page 2-3 of Reference 3, item 3 indicates that tapered wear marks were identified at two adjacent tube support plate lands. However, Table 2-3 does not identify the indications referred to in the text. Was one of the specimens not destructively examined? Please clarify.

Item 3 (Second bullet) on page 2-3 of Reference 3 discusses tapered wear defects located at the top and bottom of adjacent Tube Support Plate (TSP) lands. The text refers the reader to Figure 2-2, which is a photograph of the defects in question. The indications were at the 9th TSP of pulled tube 68-46 (Section 68-46-18). Referring to Table 2-3 under pulled tube

.- -. .- - - - - - . ~

U. S. Nuclear Regulatory Corrmasion 3F1295-03, Attachment 1 Page 42 68-46, both of these defects are indeed identified in the table. Thus, the exact nature of the RAI question is not clear.

34. Clarify the reason for the difference in the number of metallurgical indications reported in Appendix B to Reference 6 and the number reported in Table 3-1 of Reference 6. Furthermore, clarify the reason for the discrepancy between the previously cited data and the data (number of indications) reported in Tables B1/B2 of Appendix D to Attachment 2 to Reference 4. If the reasons for these discrepancies are a result of different analysts / analysis criteria, have the eddy current data analysis guidelines been improved to incorporate the best aspects of each analysis criteria?

The data in Table 3-1 is the listing of eddy current distinguishable defects present in the 1992 CR-3 pulled tubes. This information is a grouping of all defects from the destructive examination, by proximity of location, into defects which would be expected to be uniquely differentiable by NDE/ ECT. This grouping was done in order to correlate the destructive examination and NDE results. As indicated in Table 3-1, not all of the distinguishable defects were detected by means of field bobbin coil during the 1992 Outage. This was to be expected, given the probability of detection for this size (particularly volume) of indication.

Appendix B summarizes a review of CR-3 eddy current data from three consecutive outages performed by the EPRI NDE Center. Only those indications which were detected during each of the three Outages were available to be used in the study. Further, it was noted in Appendix B that only three of the six tubes pulled in 1992 were ECT inspected during these three Outages. One of the three tubes,109-30, was not destructively examined and is thus, not reported in Table 3-1.

The other reference (Appendix D) is to work the EPRI NDE Center performed to correlate eddy current voltage to volume wall loss for certain defects from the destructive examination. The work is based upon laboratory (B1) and field (B2) eddy current data analysis performed with the hindsight of the destructive examination results. This differs from the other work which was more of an objective examination of eddy current capabilities, particularly detection. The analyst performing the work in Appendix 0 apparently was comfortable assigning voltage values to the flaws as noted in Tables B1 and B2.

References A, B, and F are attached as Appendix B. Reference C is a draft-for-comment version of Reference B and has not been provided since minimal changes occurred between the two documents. Reference F has yet to be finalized and has thus, been provided in draft form. The remaining references (D, E, G, and H) have minimal direct impact to the proposed TSCRN and have not been provided for this reason. The approach taken in this response has been discussed with the NRC Staff.

36. Section 2.3.1.2 of Reference 3 indicates that the tapered wear scars ranged up to 0.64 inches in length. Table 2-3 indicates that one tapered wear scar was 0.812-inch. Clarify this discrepancy. What was the depth of this indication?

The tapered wear scar present on tube 72-49 at a location corresponding to the lower edge of the 9th Tube Support Plate (TSP) was confirmed to be 0.812 inches in length. Thus, Section 2.3.1.2 of reference 3 is incorrect. This wear scar was considered the lesser of the two tapered

U. S. Nuclear Regulatory Commiselon 3F1296-03, Attachment 1 i Pago 44 wear scars identified during visual and stereovisual examinations of the j tube section. Because of this, no further destructive examination was  !

performed (i.e., depth was not determined). Presumably, the depth of the i indication was less than that of the wear scar present at the top of TSP I location (10%) which was destructively examined.

37. The number of indications identified with the bobbin coil (3) and the RPC l (2) in the 0.075-inch to 0.099-inch bin of Figure 2-8 in Reference 3 appears l inconsistent. It seems that the number of indications should be the same for i both (i.e., either there 'were 2 or 3 indications from the destructive i examination). Please clarify the number of indications identified by destructive -

examination in the 0.075-inch to 0.099-inch bin in Figure 2-8.  ;

Three discontinuities were identified in the 0.075-inch to 0.099-inch bin  ;

found during the destructive examination of the 9R pulled tubes. . Each of  ;

these defects was identified during the field bobbin coil examination. l However, the indication present'in' tube section 109-71-7 did not receive .

a field MRPC examination prior to pulling the tube. It is summized that ]

this inspection was not . performed due to the very small bobbin coil l voltage (0.17 volts) associated with the indication. This explains the difference in the number of indications presented for the two inspection j techniques. l

38. Confirm the circumferential extent for tube section 109-71-7 listed in Table 3-2 of Reference 1.

ihe correct circumferential extent for the discontinuity found in' tube section 109-71-7 was 0.097 inches.

39. In equation 5-1 of Reference 1, an allowance for ISE uncertainty is made.

Was the adjustment made to the beginning of cycle voltage (i.e., the repair limit

voltage) or the structural limit (LL) voltage?

This question suggests some confusion with other industry Degradation Specific Management (DSM) efforts. The CR-3 approach does not utilize two separate bobbin voltage limits as do other DSM approaches. Based upon little or no degradation growth rate, the FPC approach utilizes only one limit (2.5 volts). This is the Beginning of Cycle (B0C) and the End of Cycle (E0C) limit. Additionally, this limit is not a structural limit. ,

Ensuring adequate structural integrity is accomplished by proper '

application of the proposed length and width criteria. The proposed voltage criteria is only-explicitly credited for purposes of addressing  ;

primary-to-secondary leakage under worst-case differential pressure '

conditions.

40. The labeling of the vertical axis of Figure 1-4 in Reference 3 states that the data is given 'per 100 tubes inspected." Provide graphs showing the voltage distribution of all S/Ns currently in service in steam generator "A" and steam generator "B" (i.e., exclude the tubes repaired in 1994). How many active tubes in each steam generator have S/N indications?

The graphs requested are presented as Figures 14 and 15. Based upon Refuel 9 inspection results, there were 290 active tubes in 'A' and 817 tubes in the 'B' OTSG which contained S/N indications. A review of the CR-3 historical eddy current database indicates 351 active tubes in 'A' and 892 active tubes in 'B' have been assigned an S/N code in at least one outage since 1983. The difference in the two numbers is believed to be principally attributable to certain small amplitude signals " fading" in and out from one outage to another (discussed in the response to RAI #9),

as well as a number of S/N indications which have changed designation for one reason or another over the years.

41. The results provided in Table 4-12 of Reference 1 do not correspond to the results given in your letter dated Nay 25, 1994 (pages 20 and 57 of the Attachment). Specifically, the sample size and number of failures for the second expansion do not match. Please clarify.

The information presented in Reference 1 is correct. There were no subject failures present in the second expansion sample for RCSG-1A. Further, the number of indications inspected as part of the second sample for RCSG-1B was 58 instead of the value of 56 presented on page 57 of the Attachment to the May 25th letter.

The majority of defects identified by stereovisual inspection (as well as the type of danage) were confirmed by metallography (see Figure 2-40). Again, tube degradation was primarily in the form of small patches of " thumbnail-shaped" IGA. A total of 108 defects were confirmed, with maximum and minimum depths of 62% and 1% throughwall, respectively, with an overall average depth of 28% and i a standard deviation of 16%.

i Fiaures 3-4. 3-5. and 3-6 Fifty nine of the data points are from the 1992 CR-3 tube pull originally listed in  !

Table 3-1 of (6). For convenience, these data points are included herein as a l Table, listing tube section number, defect number, and associated dimensional data. An additional data point (Defect No. G from tube section number 97-91-2) 4 was not used for correlation since it had a reported volume of 0.0 x 10 in'.

As stated in (6), these sixty data points represent clusters of defects separated  !

with an axial spacing of arproximately 0.2 inches. The volume of each defed -  !

was estimated by assuming an ellipsoidal shape for the IGA. For defects which i were combined to form a composite, axial extent and depths were de3 ermined by a weighted average (based on volume) and circumferential ex:ents were summed.

An additional eight data points are from the 1994 CR-3 tube puil and one tube pulled during 1992 but examined in conjunction with the 1994 pulled tubes.

Dimensional information was originally tabulated in Table 3-3 of (1). For convenience, these data points and their dimensions are included herein .

Axial and circumferential extents for the additional eight data points were not originally included in the correlations because the dimensional information was  ;

not available. This explains why Figures 3-5 and 3-6 from (1) have 8 fewer data i points than Figure 3-4 of (1). The dimensional information has since become l available. When the additional data is appended to the original volume-axial  !

length, volume-circumferential length data sets the correlation plots shown in the j Figures attached. These new plots with the extended data sets compare very )

well with the original plots.

Fiaure 3-7 The twelve CR-3 pulled tube data points used for voltage-volume correlation are listed in Table 3. Voltage values were obtained by reanalyzing 8R and 9R eddy current data for points that could be uniquely associated with discontinuities  !

listed in the tube pull reports. In general, association was based on volume  !

rather than location or depth since this parameter determines signal amplitude.

In addition, for multiple discontinuities within the coil field of view, volumes are additive. .

Association of particular data points with metallographic data presented in Tables 1 and 2 is shown in the last column of the table. Data for CR-31992 pulled tube 109-30 is not included in Table 1. The volume data are listed in Table 2-8 of (6) and represent a composite volume of mulitple pit-like IGA within an axial span of approximately 0.15 inches.

IV.B RAI Question Number 28 - Introductory Paragraph Discussion -

The introductory paragraph refers to two instances where the NRC Staff felt  !

there was an apparent discrepancy between data sets presented. Each of these '

is discussed below.

1 Table 3-2 is a compilation of the detectability information presented in Table 3-1 " Summary of Eddy Current Distinguishable Defects." As discussed in the response to RAI Question Number 34, the difference between the data presented in Appendix D to Attachment 2 of Reference 4 resides in the intended purpose t of the respective evaluation.

The second example cited compares 1992 pulled tube data with the population of pulled tube data following the 1994 tube pull. Presumably, the RAI is referring to the number of indications detected by MRPC since this is the subject of Table 3-1. In this case, Appendix B contained a number of detected indications based upon combined eddy current results and total defect count.

This approach was not utilized in later disposition strategy development i efforts.

' Guidelines for Leak Testing d Steam Gen:rator Tubes [

Prepamd far the EPRI ARC Committee by Watinghousa, Lsbomlec, & Packsr Engineering l

1. SCOPE.

The purpose of this guide is to describe recommended practices for the  !

measurement of fluid leak rate (s) from tubes with through-wall degradation,  ;

that are either pulled from steam generators (SG's) or produced under -l laboratory conditions. l Since acceptable leak rate testing may be performed utilizing a variety of test j facility and measuring equipment, a specific delineation of such equipment and its', configuration is not specified herein. j l

2. TEST SPECIMEN (S). j

. The test specimens should consist of tube sections approximately 10" (250 j mm) long, with the degraded area located as close as practicable to the mid-length position of the specimen. In specific cases lengths as short as 6" (150 mm) may bejustified.

If the degradation is visible at the tube outside diameter (OD) surface, a good quality (preferably color) photograph should be taken of the degraded area.

3. PROCEDURE RECOMMENDATIONS.

Testing shall be performed in accordance with a viritten test procedure. The test procedure shal. be aimed at providing a direct or adjusted evaluation of

• the leak rate to be expected under the specified environmental conditions, e.g.,

the internal and external pressure, temperature and fluid conditions, of inferest.

Note: Usually the desired leak rate is for faulted conditions, with the water pressure and temperature specified on the primary side, and an i essentially zero (ambient) pressure vapor phase on the secondary side. i The leak rate measurement (s) shall be performed at a differential pressure closely matching the actual SG conditions (as specified).

It is further desirable, but, not mandatory, that the testing conditions fully duplicate the specified environment, including the SG operating temperatures.

Adjustments to the measured leak rates are required when the absolute pressures (both sides of the tube) and/or the temperatures are not prototypic.

Guidallnes for Leak Testing of Steam Gen:rator Tubes

• Pmp2nd far the EPRI ARC Committe2 by W43tingh use, L:bomlec, & Prek;4r Engineering i L This is always the case for room temperature testing. While such an l

} adjustment procedure involves some additional uncertainty, the latter is  !

!- usually considered to be much smaller than the scatter of leak rates from '

nominally similar crack morphologies, i.e., as characterized by standard non-destructive examination (NDE) techniques. l l Even if the test is performed at the specific differential pressure, it is - t j desirable, but, not mandatory, to gain some knowledge about the rate of

! change ofleak rate with pressure. This addresses a sensitivity concern, and i may provide a basis for the possible extrapolation or interpolation of the  :

results to other faulted conditions that might be further considered by plant J safety evaluations, i

It is recommended that additional leak rate measurements, preferably three  !

or four, be performed at selected pressure difference levels ranging from not i lower than the normal operation condition to not higher than 110% of the specified faulted condition.  !

1 The leak test duration, i.e., time at each pressure level, should be determined  !

based on the required measurement accuracy and the measuring equipment being used. ~ Replicate tests for each configuration are recommended. Due to plasticity effects, crack opening areas are path dependent. Therefore, leak  ;

rate measurements at a low pressure difference will increase markedly after exposure to a higher pressure difference. Transient pressure fiuctuations during the approach to steady state test conditions should thus be controlled to avoid unwanted crack opening deformation.

- The measurement system should be capable of providing reliable leak rate results in the range from 0.01 to 1001/h, with an accuracy of plus or minus 10%.

4. TEST EQUIPMENT Test equipment may vary widely, depending on the selected testing conditions and method. In general terms, the following may be required:

1) a supply system, delivering the high pressure, and possibly high temperature, water into the primary side of the test specimen,

2) a secondary side enclosure, in the case of high temperature testing, with possible provisions for:

t i The int'egrated testing facility should be qualified. Such qualification should I

consist of demonstrating its' functional capability over the full range of l

i.

l Attention should be~ paid to functional limitations that might impair the nominal measuring ranges, e.g., when the order of magnitude of the flow  ;

i resistance of piping connections becomes comparable to that of the cracked specimen. ,

4. DOCUMENTATION a

l Leak rate testing should comply with all relevant quality assurance (QA) .

Guidelines for Burst Testing of Steam Generator Tubes _

Prep: red for the EPRI ARC Committee by Wutinghouse, Laborelee, &

1. SCOPE.

The purpose of this guide is to define the configuration of test specime equipment and setup, and the procedure to be used for the burst testinii degraded tubes that are either: 1) removed from steam generators (SG produced in a laboratory under simulated field conditions, or 3) produ{ '

suitable or 0.3 mm).artificial simulation, e.g., EDM slots (with widths not exceedin

2. i TEST SPECIMEN (S).

The test specimen will be a tube section approximately 10 inches (250 long, with the degraded area located at mid-length (as close as practic In specific cases lengths as short as -6" (150 mm) may be justified.

I In order to prevent leakage before burst, an unreinforced plastic bladd 1 to 0.125" (2 to 4 mm) thick, will be inserted in the specimen.

The bladder OD is to be matched as close as practicable to the tube ID, and is to be mechi cally sealed at both ends of the specimen.

NOTE: The total bladder thickness may be achieved by the use of m!

l concentric bladders. The use of more than two (2) concentric bl i achieve the desired thickness is not recommended.

If the degradation is through or nearly through, and/or the specimen is technically valuable, e.g., a pulled tube section or a unique prototype it is i

recommended that the bladder be reinforced with a thin metal foil s i inserted between the tube defect and bladder.

In case of a premature bladder failure (extrusion through the defect o before tube burst) in a prior pressurization test (of the actual specimen or other similar specimens), (re) pressurization shall be achieved utilizing a reinforcing foil as described in the following paragraph.

If reinforcing foil is used, it shall be of brass or copy a co 8 mils (0.1 to 0.2 mm) thick, about 0.4" to 0.5" (~10 to 12 mm) wide e M with a length not exceeding the ends of the defect by more than 0.25" (6 mm). Alternatively the foil may be stainless steel, 2 to 4 mils (0.05 to 0.1 mm) thick. The foil should be centered on the degradation. Proper angular positioning of the f may require information about the (largest) defect from a dye penetrant, RPC and/or UT inspection relative to a known reference point on the specimen.

Guidelines for Bumt Testing of Steam Generator Tubes  !

Prepared for the EPRI ARC Committee by Wutinghsuse, Laborelee, & Packsr Engineering j i The use of a reinforcing shim' may result in a measured burst pressure greater  !

than the actual value; therefore a corrected, or adjusted, burst pressure shall '

be obtained by applying a 5% reduction to the measured burst pressure.

+  :

The specimen shall be connected to the test rig by Swagelok' or equivalent ,

type fittings; this may include a " union" connection to a tube extension if- l required for proper simulation of environmantal constraints, e.g., for a circum- l ferential crack with lateral motion of the tube constrained by a tube support 1 plate. j Considering the defect to be oriented at the O' azimuth, the tube outside diameter (OD) shall be measured at the O' and 90' azimuth locations, at the defect axial location, at both ends of the specimen, and at the level of any i external constraint (s) of the specimen or the tube extension. For specimens in which the defect is a machined slit, the OD measurement at the O' azimuth should be performed before the machining process. j i

The tube thickness shall be measured at both ends of the specimen at the  !

same azimuth orientations. It is also recommended that the thickness be measured at each end of the specimen at the 180' and 270* azimuth locations.

The thickness measurements should be direct if practicable, e.g., pin microme-ter. If direct measurement of the thickness cannot be effected, inside diame-ter (ID) and outside diameter measurements may be made and the thickness calculated.

If the defect is visible at the tube OD surface, a good quality (preferably color) photograph shall be taken of the degraded area. Inclusion of a scale in the photograph is recommended but not mandatory.

A virgin control specimen with known or tested material properties shall be prepared for testing with each series (defined as requiring a separate test equipment setup) of test specimens. i

3. TEST RIG.

If required to obtain a representative burst pressure, the test specimen will be i placed in a test rig simulating the geometrical constraints acting under actual l steam generator conditions. The tube support conditions above and below the tube degradation location in the steam generator should be simulated for the burst test. For example, if the failure mode implies significant bending as could be the case for circumferentially oriented defects at the top of the tubesheet, an assembly of a split collar (no gap) as a tubesheet simulant and i sm suarrcuios Page 2 of 6 u rt. im

i Guidelines for Burst Testing of Steam Gen:rator Tubes Prepared fer the EPRI ARC Committee by Wutinghouse, Liborelee, & Packtr Enginecring ring collar (s), with controlled gap, to simulate the tube support plate (s), linked together by a rigid axial frame, would be required to simulate the restraining effect of the tube support plates. I

4. TEST EQUIPMENT. l The test equipment consists mainly of pressurizing devices and measuring instruments.  !

(1) Pressurizing is achieved by a cold incompressible medium such as water or, oil. The pressurizing system consists of a pump, an air-driven pres-sure multiplier and/or ancillary devices, allowing a controlled pressure ,

rise (with minimum pressure fluctuations) up to a pressure on the order l of 13000 psi (900 bar).

NOTE: A system capability of 15000 psi (1034 bar) may be necessary for l burst testing of U-bend specimens. The capacity of the equipment  :

must exceed the strength of the specimen.

l (2) The measuring / recording system shall include at least:

(a) a pressure transducer (two are recommended for pulled tube tests to avoid loss of data in the event of a malfunction)

(b) a recording device, e.g., tape or pen plotter, etc. (two are recommend-ed for pulled tube tests to avoid loss of data in the event of a mal-function)

Additional features are recommended to provide redundancy to compensate for the potential malfunctioning of any part (with proper attention paid to such common failure modes as associated with power supply).

All instruments, gauges and test equipment shall be calibrated prior to testing (unless valid calibration certificates are already available) and recalibrated after testing in case of disagreement between the independent measurement channels, if present, or if there is any reason to suspect the validity of the ob-served results. Calibrations shall be traceable to the appropriate national standards institute for the country in which the tests are preformed.

Guidelines for Burst Testing of Steam Gen:rator Tubes Prepared f;r the EPRI ARC Committes by Wutinghouse, L borelee, & Pecksr Engineering

5. TEST PROCEDURE.

(1) Prepare specimens as defined under 92. Note that the control specimen is to be tested first.

(2) Take dimensional measurements and defect photographs, if not previous-ly obtained.

(3) Attach the specimen to the test rig (extension tube, if applicable) and pressurizing system; over torquing of the sealing fittings is permitted if ,

leakage is observed during test. ,

(4) Check the availability of the measurement equipment and its' calibration  :

l data (as defined under f4).

(5) Verification of the settings of the instrumentation shall be based on the i results to be obtained from the control specimen.

(6) Fill and bleed the hydraulic system. l

'l (7) Turn-on the recorder (s)just before pressurizing the system.

(8) Increase the primary side pressure at a rate between 200 and 2000 psi /second (15 to 150 bar/sec). Pressurization rates in the upper half of l the specified range are recommended when no reinforcing foil is being used because rates in the lower half of the range, e.g., less than 1000 ,

psi /sec (70 bar/sec), may affect the integrity of the bladder seal.

(9) Turn-off the recorders and the pressurizing system after burst of the specimen (or seal failure) has occurred.

(10) Disassemble and examine the test specimen. If the defect has not ex- '

tended by tearing beyond its initial length and/or does not exhibit signifi-cant bulging / fishmouth opening, premature bladder failure has occurred, and the recorded pressure is but a lower bound for the actual burst pressure.

In such a case, it is recommended that repressurizing be performed after reinforcing the bladder arrangement, as indicated under 52. If prema-ture bladder failure is suspected, such shall be documented in the test record.

Guidelines for Burst Testing of Steam Gen:rator Tubes Prepared f r the EPRI ARC Committee by Wetinghiuse, Laborelee, & Pick:r Engine: ring (11) Take good quality (preferably color) photographs of the burst opening. j l

(12) Measure the defect dimensions (final length and opening width) and any other noticeable change of the degraded area. Diametral measurements should be made at the bulge location, including the maximum diameter 1 to the lip of the burst opening and at 90* to that location, and at loca-tions remote from the burst opening NOTE: Additional measurements may be specified as required depending on the planned end usage of the data.

6. QUALITY ASSURANCE.

Burst pressure testing should comply will all relevant QA requirements in effect at the testing laboratory organization.

As a minimum, documentation shall include:

(1) a written test procedure ,

(2) a test report with (a) full specimen identification (b) a sketch / schematic or written description of the test setup (c) a sketch of support details with pertinent dimensions, if special support of the specimen is employed  !

1 (d) test equipment serial numbers (e) (reference to) instrument calibration data (0 description (with dimensions) of the specimen sealing system (g) maximum recorded pressure (with a statement of qualification as valid burst pressure). If a reinforcing foil has been used, both the measured and corrected values are to be reported.
