• Wolf Creek PG&E Letter DCL-07-106 180-DAY STEAM GENERATOR REPORT FOR DIABLO CANYON POWER PLANT UNIT 1 FOURTEENTH REFUELING OUTAGE Pacific Gas and Electric Company (PG&E) performed eddy current inspections of the Diablo Canyon Power Plant (DCPP) Unit 1 steam generators (SGs) during May 2007.

The inspections were conducted in accordance with DCPP Technical Specification (TS) 5.5.9. TS 5.5.9 was revised in accordance with NRC letter dated March 21, 2007, transmitting License Amendment 194/195 prior to the Unit 1 Fourteenth Refueling Outage (1 R14) SG inspections to incorporate Technical Specification Task Force (TSTF) 449, Revision 4, requirements. 1 R14 was the third, and last refueling outage in the current DCPP Unit 1 60 effective full power month (EFPM) period for Alloy 600 mill annealed SG tubing. The current period includes the Unit 1 Twelfth Refueling Outage (1R12), Unit 1 Thirteenth Refueling Outage (1R13), and 1R14. This inspection of the DCPP Unit 1 Model 51 SGs was the last inspection as replacement SGs are scheduled to be installed during the Unit 1 Fifteenth Refueling Outage (1R15).

1.0 Technical Specification 5.6.10.a Reporting Requirements Pursuant to TS 5.6.10.a, a report shall be submitted within 180 days after initial entry into Mode 4 following completion of an inspection performed in accordance with Technical Specification 5.5.9.

The specific TS reporting requirements are listed in italics below, followed by PG&E's description of compliance.

1. The scope of inspections performed on each SG, Table 1 provides a summary of eddy current inspections performed in each SG,

2. Active degradation mechanisms found, The following active alternate repair criteria (ARC) degradation mechanisms were found, and reporting of condition monitoring and operational assessment (CMOA) is documented in PG&E letter DCL-07-085, "Results of Steam Generator (SG) Tube Alternate Repair Criteria (ARC) Inspections for Diablo Canyon Power Plant Unit 1 Fourteenth Refueling Outage," dated August 27, 2007:

o Axial primary water stress corrosion cracking (PWSCC) in hot leg WEXTEX tubesheet region o Axial PWSCC at hot leg dented tube support plate (TSP) intersections o Axial outside diameter stress corrosion cracking (ODSCC) at hot leg TSP intersections 1-1 PG&E Letter DCL-07-106 The following active non-ARC damage mechanisms were found:

o Circumferential ODSCC and PWSCC at hot leg dented TSP intersections o Combined axial PWSCC and axial ODSCC at hot leg dented TSP intersections (referred to as inside diameter/outside diameter (ID/OD) indications) o Circumferential ODSCC at hot leg WEXTEX top of tubesheet region o

Axial ODSCC at hot leg WEXTEX top of tubesheet region o Volumetric OD indications at hot leg TSP intersections o Cold leg thinning at cold leg TSP intersections o Antivibration bar (AVB) wear in U-bend region o TSP ligament thinning/cracking (Note: This damage mechanism relates to support structure degradation, not SG tubing degradation.)

3. Nondestructive examination techniques utilized for each degradation mechanism, Table 1 provides the nondestructive examination (NDE) techniques (bobbin and Plus Point probes) utilized for each inspection category. The degradation-specific analyses in this enclosure provide more detailed discussion of the probes used to identify and size the degradation mechanism.

4. Location, orientation (if linear), and measured sizes (if available) of service induced indications provides a list of all service induced indications, including location, orientation (if linear), and measured sizes (if available). Enclosure 2 also identifies tubes that were plugged and provides the reason for tube plugging.

Bobbin indications that were not confirmed by Plus Point are not reportable indications; however, these bobbin indications are included Table 1 for completeness. Historical free span indications that had eddy current signals traceable to preservice inspection data (e.g., manufacturing burnish mark) are not considered as reportable indications and are not included in Enclosure 2. includes measured through-wall (TW) depth penetrations of antivibration bar (AVB) wear and cold leg thinning indications. Measured percent TW depth penetrations of PWSCC ARC and W* ARC crack-like indications have been previously submitted to the NRC in letter DCL-07-085. Tables 5, 7, and 8 of this enclosure provides estimated measured percent TW depth penetrations of non-ARC crack-like indications.

Detected indications that are located in carbon steel tube support plates (e.g., suspected TSP ligament indications) are not included in Enclosure 2, as the indications are not contained in the tubing material.

5. Number of tubes plugged during the inspection outage for each active degradation mechanism, Table 2 provides the number of tubes plugged during 1 R14 for each active degradation mechanism. The cumulative number of tubes plugged for each degradation mechanism is shown in Table 3 (by SG) and Table 4 (by outage).

A total of 62 tubes were plugged. Areva Alloy 690 roll plugs were used in both legs.

Tubes with circumferential indications were evaluated for stabilization prior to plugging. Westinghouse stabilization analysis determined that three tubes required stabilization (see Table 5 for locations), and tubesheet stabilizers were inserted in these tubes during plugging.

6. Total number and percentage of tubes plugged to date, Table 2 provides the total number and percentage of tubes plugged to date, by SG and overall. No tubes have been repaired by sleeving.

7. The results of condition monitoring, including the results of tube pulls and in-situ

testing, There were no tube pulls or in-situ testing performed in 1 R14.

Section 4 provides the degradation-specific results of condition monitoring (CM) and operational assessment (OA) for all active non-ARC damage mechanisms. The OA is provided for information and completeness. PG&E letter DCL-07-085 provided CM and OA for all ARC damage mechanisms.

Section 4 also provides an assessment of installed hardware for leakage during normal and steam line break conditions, to support the conclusion that no CMOA accident induced leakage should be postulated for installed plug hardware.

Section 5 provides the results of 1 R14 inspections for previously active or potential degradation mechanisms that were not detected in I R14, as listed below:

o Axial and Circumferential PWSCC in Rows 1 and 2 U-bends o Circumferential PWSCC in Rows 3 to 8 U-bends o

o Secondary side integrity and potential tube damage due to loose parts and foreign objects 1-3 PG&E Letter DCL-07-106 2.0

Background

Steam Generator Description The commercial operation dates for Units I and 2 are May 1985 and March 1986, respectively. DCPP Units 1 and 2 use Westinghouse Model 51 SGs with explosively expanded (WEXTEX) transitions. The SGs contain Alloy 600 Mill Annealed tubing.

The nominal outside diameter of the tubing is 0.875 inch with a 0.050 inch nominal wall thickness. DCPP Unit 1 and 2 SGs currently operate with a nominal hot leg temperature (Thot) of about 604 degrees. The cycle lengths vary to support a nominal 20-month operation period. Unit 1 Cycle 14 had an actual duration of 1.39 effective full power years (EFPY). Unit 1 Cycle 15 has a projected duration of 1.63 EFPY.

PG&E has implemented several initiatives to minimize PWSCC and ODSCC. Primary side initiatives includeU-bend heat treatment, WEXTEX tubesheet shotpeening, and zinc injection. Secondary chemistry initiatives include: copper removal program; ethanol amine to control pH; increased hydrazine levels; molar ratio control program to prevent excess alkalinity; boric acid addition program (including boric acid soaks at startup to mitigate denting and ODSCC at TSPs); periodic tube sheet sludge lancing; SG blowdown is maintained at one percent of the main steam flow rate; condensate polishers were installed and emergency (plant curtailment) procedures issued to protect against seawater condenser tube leaks; chemical cleaning in 1 R12 and Unit 2 Twelfth Refueling Outage (2R12).

Technical Specification Repair Criteria DCPP TS require plugging of any tube that has degradation greater than or equal to 40 percent of the nominal tube wall thickness, unless ARC are implemented. Other than degradation subject to ARC, all crack-like indications are required to be plugged on detection by a rotating coil probe, regardless of depth measurements. Cold leg thinning and AVB wear are sized by bobbin and allowed to remain in service if less than 40 percent TW.

Several ARC are implemented in DCPP Units 1 and 2:

In March 1998, the DCPP TS were revised to allow implementation of ARC for ODSCC at TSPs pursuant to NRC Generic Letter (GL) 95-05, "Voltage-Based Repair Criteria for Westinghouse Steam Generator Tubes Affected by Outside Diameter Stress Corrosion Cracking." ODSCC ARC was implemented starting in Unit 2 Eighth Refueling Outage (2R8) for Unit 2 and Unit 1 Ninth Refueling Outage (1 R9) for Unit 1. The ODSCC ARC TS changes were granted by the NRC in License Amendment (LA) 124/122 dated March 12, 1998, in response to License Amendment Request (LAR) 97-03. Use of an improved probability of detection (POD) method, referred to as probability of prior cycle detection, was approved for both units in LA 177/179 dated October 28, 2004, in response to LAR 04-01.

1-4 PG&E Letter DCL-07-106

" In February 1999, the DCPP TS were revised to allow implementation of Wstar (W*)

ARC for axial PWSCC in the WEXTEX tubesheet region. W* ARC was implemented starting in 1 R9 and Unit 2 Ninth Refueling Outage (2R9). The W* ARC TS for Cycles 10 and 11 were granted by the NRC in LA 129/127 dated February 19, 1999 (in response to LAR 97-04). The W* ARC TS for Cycles 12 and 13 were granted by the NRC in LA 151 dated April 29, 2002 (in response to LAR 01-03). Use of W* ARC on a permanent basis beyond Cycle 13 was granted by the NRC in LA 182/184 dated October 28, 2005 (in response to LAR 05-01).

" In May 2002, the DCPP TS were revised to allow implementation of ARC for axial PWSCC at dented TSPs. The PWSCC ARC TS changes were granted by the NRC in LA 152 dated May 1, 2002 (in response to LAR 00-06, Supplement 3). PWSCC ARC was implemented starting in Unit 2 Eleventh Refueling Outage (2R1 1) and Unit 1 Eleventh Refueling Outage (1 R1 1). Validated depth sizing of axial PWSCC at dented TSP intersections was previously implemented in 1 R9 and Unit 1 Tenth Refueling Outage (1 R1 0) for Unit 1; and 2R9, and Unit 2 Tenth Refueling Outage (2R1 0) for Unit 2, such that axial PWSCC less than the TS limit of 40 percent maximum depth (MD) limit was allowed to remain in service.

3.0 Condition Monitoring and Operational Assessment Summary NEI 97-06, Revision 2, and DCPP Technical Specification 5.5.9 provides structural integrity performance criteria (SIPC), accident induced leakage integrity performance criteria (AILPC), and operational leakage performance criteria. These performance criteria were satisfied at the Unit 1 End of Cycle (EOC) 14 based on a condition monitoring assessment, and are projected to be satisfied at EOC 15 based on an operational assessment. This conclusion is based on assessing the conditions of the SG tubing on a degradation-specific basis.

Structural Integrity Performance Criteria:

Three times normal operating pressure differential (3dPNO) and 1.4 times steam line break differential pressure (1.4dPSLB) are the burst margin requirements for free span degradation, and degradation confined to the TSP crevice, respectively. SIPC are satisfied at EOC 14 and EOC 15. (Note: See PG&E letter DCL-07-085 for discussion of W* ARC, PWSCC ARC, and GL 95-05 voltage-based ARC).

Accident-Induced Leakage Integrity Performance Criteria:

For degradation subject to ARC, the maximum allowable steam line break (SLB) induced leak rate limit is 10.5 gallons per minute (gpm) at room temperature in a faulted SG, based on an analysis which uses current licensing basis assumptions and is approved by the NRC. As described in Enclosure 1 to PG&E letter DCL-07-085, the aggregate SLB leak rate from ARC degradation and non-ARC degradation in the limiting SG is 0.95 gpm (at EOC 14) and 3.07 gpm (at EOC 15).

1-5 PG&E Letter DCL-07-106 These leak rates are less than the 10.5 gpm acceptance limit. Therefore, AILPC for ARC degradation are satisfied at EOC 14 and EOC 15.

For degradation not subject to ARC, the maximum allowable accident-induced leak rate in all four SGs is 0.54 gpm at room temperature. There is no accident-induced leakage attributed to any non-ARC degradation at EOC 14 and EOC 15. Therefore, AILPC for non-ARC degradation are satisfied at EOC 14 and EOC 15.

Operational leakage performance criterion: Primary-to-secondary leakage through any one SG must be limited to 150 gallons per day (gpd).

In Unit 1 Cycle 14, a small leak (0.02 gpd) was detected and measured in the steam jet air ejector. Subsequent weekly sampling showed no increase in leak rate. The source of the small Cycle 14 leakage was not confirmed by eddy current inspections in 1R14.

There are no indications of primary to secondary leakage thus far in Cycle 15.

4.0 Degradation-Specific Condition Monitoring and Operational Assessment for Active Non-ARC Damaqe Mechanisms 4.1 Circumferential ODSCC and PWSCC at Dented TSP Intersections (Active)

Condition Monitoring Thirteen circumferential ODSCC indications and one circumferential PWSCC indication were detected by Plus Point at dented hot leg TSP intersections, as listed in Table 5.

All the circumferential indications (SCI) were plugged. All of the dent voltages associated with circumferential cracking were greater than or equal to 4.95 volts.

Circumferential PWSCC and ODSCC indications at dented TSPs are capable of being detected by Plus Point using EPRI ETSS 20510.1 and 22842.3, respectively.

The circumferential indications were sized by Plus Point using the technique described in Appendix B of WCAP-1 5573, Revision 1. The depth profiles were then processed for corrections in accordance with the depth adjustment rules in Section 4.10.4 of WCAP-1 5573, Revision 1. The adjusted NDE results were corrected for 95 percentile NDE uncertainty using the NDE uncertainty regression parameters in WCAP-1 5573, Revision 1. The adjusted NDE and adjusted NDE with uncertainty results are listed in Table 5.

The 3dPNO structural limit for a straight leg SCI is 265 degrees, assuming a 100 percent TW defect, and 73.5 percent degraded area (PDA). From Table 5, the longest NDE length was 74.4 degrees, and is adjusted to 191.2 degrees after applying large 95 percentile NDE uncertainties. This length is less than the 265 degree structural limit. Therefore, structural integrity was satisfied at EOC 14.

1-6 PG&E Letter DCL-07-106 The maximum Plus Point voltages of the 1 R14 TSP circumferential ODSCC and PWSCC indications were 0.37 volt and 0.91 volt, much less than the 1.31 volts and 1.25 volts thresholds for leak testing of circumferential ODSCC and PWSCC indications at explosive expansions, respectively, documented in Revision 2 of the EPRI In-Situ Pressure Test Guidelines. The associated maximum depths of these bounding flaws, including 95 percent NDE uncertainty, were 68 percent (ODSCC) and 64.2 percent (PWSCC). Therefore, no SLB leakage should be postulated for circumferential indications at EOC 14.

Operational Assessment All TSP intersections containing circumferential ODSCC and circumferential PWSCC were also inspected by Plus Point in the previous outage (1R13). All of the indications were detectable in 1R13 data based on a lookup. The growth rates were very small as noted in Table 5. Adding these growth rate data points to the existing database from WCAP-1 5573, Revision 1, plus data points from 1 R1 1 to 1 R1 3 and 2R1 1 to Unit 2 thirteenth refueling outage (2R13) results in the following growth rates (based on the empirical distribution function of the median rank fraction).

Length 14 deg 23 deg Number of DCPP data points 28 67 in growth distribution The limited data would indicate that PWSCC depth growth rates are larger than ODSCC. ODSCC depth growth rates are conservatively assumed to be the same as PWSCC depth growth rates.

The average depth (AD) growth data at 95 percent cumulative probability can be combined with the estimated detection thresholds derived from destructive examination (25 percent and 35 percent AD detection thresholds estimated for PWSCC and ODSCC, respectively, per WCAP-1 5573, Revision 1, Section 4.11, no NDE uncertainty is necessary) to obtain a deterministic projection of expected EOC 15 average depth for circumferential indications, as given in the following table.

1-7 PG&E Letter DCL-07-106 Assuming that the worst case projected flaw is 56 percent AD over 360 degrees results in a conservative EOC 15 projection of 56 PDA. This conservative projection is less than the straight leg circumferential indication structural limit of 73.5 PDA. Since the largest circumferential crack angle at 1 R14 was 191.2 degrees including adjustment for angle uncertainty at 95 percent probability, the assumption that the projected EOC 15 indication is 360 degrees is very conservative.

Similar to above, the MD growth data at 95 percent cumulative probability can be combined with the estimated detection thresholds based on the minimum values used in the sizing adjustment procedures (45 percent and 35 percent maximum depth for ODSCC and PWSCC, respectively, per WCAP-15573, Revision 1, Section 4.10.4, no NDE uncertainty is necessary) to obtain a deterministic projection of expected EOC 15 MDs, as given in the following table.

Largest found at 1R14 39%

76%

The projected EOC 15 maximum depths of 64 and 74 percent present no challenge to SLB leakage integrity.

Based on the comprehensive inspection of dented TSP intersections during 1R14, the slow rate of circumferential degradation growth, acceptably low detection threshold, limited maximum angular extent associated with circumferential cracks, and the large structural margin associated with circumferential indications, no TSP circumferential indications are expected that would challenge structural performance criteria at EOC 15. Since the largest projected MD is not near TW, it is also unlikely that TSP circumferential indications will tear ligaments and pop through over the next cycle.

Therefore, no leakage is postulated in a faulted SG following a SLB at EOC 15.

4.2 Combined Axial PWSCC and Axial ODSCC at Dented TSP (Active)

Condition Monitoring In 1 R14, three tubes were identified by Plus Point with combined axial PWSCC and axial ODSCC (ID/OD) indications located at the same dented TSP intersection. Table 6.

provides a list of these indications. These tubes were plugged because this type of flaw combination is excluded from both PWSCC ARC and ODSCC ARC application. Two of the axial PWSCC indications had been left inservice in 1R13 using PWSCC ARC and the other axial PWSCC indication was new. All of the axial ODSCC indications were new.

1-8 PG&E Letter DCL-07-106 PG&E Letter DCL-02-098, "Special Report 02 Results of Steam Generator Inspections for Diablo Canyon Power Plant Unit 1 Eleventh Refueling Outage," to the NRC dated August 22, 2002, derived a bounding conservative hoop direction ligament length of 0.1 inch (two times the tube wall thickness of 0.050 inch), such that if this separation distance is met or exceeded, there is no interaction relative to either burst pressure or leak rate.

Based on review of the eddy current data and terrain maps for all 1 R14 ID/OD intersections, the axial PWSCC and axial ODSCC components are separated by hoop direction ligament gaps. Table 6 provides the separation gap distances (angles) between the ID and OD indications detected in 1R14. The shortest 1R14 gap is 58 degrees (about 0.44 inch). This separation distance exceeds the required hoop direction ligament thickness of 0.1 inch. Therefore, for condition monitoring, the flaws are treated independently under their respective ARC for structural and leakage integrity. Based on those independent evaluations, all indications met both structural and leakage limits at EOC 14.

Operational Assessment Extent of Inspection at Dented TSP Intersections All ID and OD bobbin indications in any size dent were Plus Point inspected. In addition, a detailed Plus Point inspection program of dented intersections was conducted, which included 100 percent inspection of greater than 2 volts dents up to coldest TSP elevation with any PWSCC indication, plus 20 percent at the next coldest TSP elevation.

Based on the extent of the inspection and repair of all detected combined ID/OD indications, any potential combined PWSCC and ODSCC indications left in service at dented TSP intersections would have one of the indications below the detection threshold of the Plus Point coil or both of the ID/OD indications would be new indications. The Plus Point detection threshold is expected to be less than 30 percent and 20 percent MD for ODSCC and PWSCC axial indications, respectively. As a consequence of the low detection thresholds and modest crack depth and length growth rates for both axial PWSCC and ODSCC, deep new indications would not be expected at EOC 15.

Number of Occurrences of Combined Axial PWSCC and ODSCC Indications A total of 104 TSP intersections have been identified with combined ID/OD indications, 12 for Unit 2 and 92 for Unit 1. Fifty-two of these TSP intersections were in tubes that were previously inactive, i.e., tubes that were deplugged and then replugged in the same outage. Therefore, only 52 TSP intersections were in active tubes at the time the ID/OD indications were detected, and Table 6 provides NDE data on these indications.

1-9

Enclosure I PG&E Letter DCL-07-106 Dependence of Combined Axial PWSCC and ODSCC Indications on Dent Voltage The vast majority of the ID/OD intersections have small dents, less than 5 volts. Only two intersections have greater than 5 volts dents, and these are in deplugged tubes.

The dominance of axial ODSCC at non-dented TSP intersections or intersections with small dents is expected based upon experience in eddy current examination of greater than 5 volts dents as part of ODSCC ARC applications. Few indications have been reported in greater than 5 volts dents under ARC applications for many plants. For DCPP Units I and 2, axial ODSCC has been detected in only 30 intersections with greater than 5 volts dents, with the first occurrences in 1 R9 and 2R9, none in 2R1 1, 6 in 1R12, 1 in 2R12, 4 in 1R13, 2 in 2R13, and 6 in 1R14. This number is small when compared to the large number of Plus Point inspections of greater than 5 volts dents, and also small when compared to the number of ODSCC signals detected in both units

.(greater than 1000 indications in each unit since 1 R1 1/2R1 1). When the intersection is highly dented, corrodents can be expected to have increased difficulty in concentrating within the crevice, and axial ODSCC is very infrequent in large dents. Consequently, the potential occurrence of combined ID/OD indication can be expected to be dominantly limited to dents less than 5 volts as supported by DCPP Units 1 and 2 inspection results. This limits the potential population of TSP intersections with significant potential for combined ID/OD indications, and also increases the likelihood of bobbin detection in less than 5 volts dents.

Crack Sizes for Combined Axial PWSCC and ODSCC Indications For previously active tubes, Table 6 provides the Plus Point sizing of the 1 R14 and previous PWSCC indications at TSP intersections with ODSCC indications, along with the Plus Point and bobbin voltages for the ODSCC indications. The listed bobbin voltage is either the bobbin distorted OD signal (DOS) indication voltage or, if the bobbin indication was not detectable, an inferred voltage based on the square root of the sum of squares of the all the Plus Point ODSCC voltages. The largest maximum and average depths for the PWSCC indications at these intersections are shallow, only 67 percent and 52.7 percent, respectively. New PWSCC indications are also small as discussed below. The largest voltages for the ODSCC indications at these intersections are 4.58 bobbin DOS volts, which is influenced by both the PWSCC and ODSCC axial cracks, and 2.66 Plus Point volts. The 4.58 bobbin voltage is well below the ODSCC ARC structural limit of about 9 volts, and would have less than a 50 percent probability of leaking as a free span indication, per the ODSCC ARC correlations. The 2.66 Plus Point volts is less than the 2.75 volts threshold applied for amplitude sizing of ODSCC indications that has been found to result in good agreement with DCPP pulled tube TW lengths. The other ID/OD indications are small, and it can be expected that all indications found to date at TSP intersections with combined ID/OD cracks have large structural margins and no leakage.

1-10 PG&E Letter DCL-07-106 New Indication Crack Sizes and Growth Rates New indication crack sizes are of interest for assessing potential interaction between the ID and OD indications, because one or both indications must be a new indication.

Both the ID and OD new indications are small.

The largest maximum and average depths for new PWSCC indications at any TSP intersection in 1R14 are 57 percent and 35.3 percent, respectively. The largest new ODSCC indication at any TSP intersection in 1 R14 has a bobbin coil voltage of 1.20 volts; and the average ODSCC bobbin voltage for new indications in 1 R14 is 0.37 volt, excluding axial ODSCC not detectable by bobbin (AONDB) indications.

From Table 6, the largest new ODSCC indication at a TSP with ID/OD indications had a bobbin DOS voltage of 1.29 volts, which is influenced by both the PWSCC and ODSCC indications, and a largest Plus Point voltage of 0.38 volt. The largest new PWSCC indication at a TSP with ID/OD indications had a MD of 51 percent.

Since both the new PWSCC and ODSCC indications are small, the structural influence of a new ID or OD indication interacting with an indication left in service would be small even under the very low likelihood of closely spaced indications.

The axial PWSCC MD, AD, and length growth rates from Unit 1 Cycle 14 are small.

The upper 95 percent growth rate for new and repeat ODSCC indications in Unit 1 Cycle 14 is 0.17 volt/EFPY and 0.20 volt/EFPY, respectively, showing that new indication growth is smaller than growth of prior indications. Based on the modest growth rates for new PWSCC and ODSCC indications, any new indications occurring to obtain combined ID and OD flaws at the same intersection would continue to be small indications.

Separation Distances Between Axial PWSCC and ODSCC Indications Based on review of the eddy current data and terrain maps for DCPP Units 1 and 2 intersections with combined ID/OD indications, the axial PWSCC and axial ODSCC components are separated by hoop direction ligament gaps in excess of about 30 degrees (0.23 inch). The angles separating the PWSCC and ODSCC indications are given in Table 6. For TSP with multiple indications, the reported angle is the minimum separation distance. The separation distances are measured as distances between the peak amplitude responses, which is preferred given the width of a rotating pancake coil response. The lowest separation angle found in DCPP Units 1 and 2 is 34 degrees (0.26 inch), found at 1 R1 1. The separation angles between axial PWSCC and ODSCC indications are predominantly in the 40 to 90 degree range. This range of separation angles can be expected based upon the separation distances between the locations of maximum hoop stress on the tube ID and OD at dented TSP intersections, as previously discussed in PG&E Letter DCL-02-098.

1-11 PG&E Letter DCL-07-106 Conclusions Relative to Closely Spaced Axial PWSCC and ODSCC Indications at Dented TSP Intersections Based on the assessments provided in PG&E Letter DCL-02-98, the potential for closely spaced axial PWSCC and ODSCC macrocracks at the same dented TSP intersection is negligible due to the high compressive OD hoop stresses near the minor axis of dent ovalization where the PWSCC occurs. Even the potential for shallow ODSCC microcracks is negligible unless formed prior to the denting, which occurred in the first cycle of operation for the DCPP SGs. Consequently, combined PWSCC and ODSCC indications at the same dented TSP intersection would have no impact on the operational assessment, and separate operational assessments for the individual indications are appropriate.

4.3 Circumferential ODSCC at Top of Tubesheet Region (Active)

Condition Monitoring Circumferential ODSCC indications at the top of tubesheet are capable of being detected by Plus Point using EPRI ETSS 21410.1.

Seventeen circumferential ODSCC indications (SCI) in the hot leg top of tubesheet WEXTEX transition region were detected by Plus Point in 1 R14. The circumferential indications were sized by Plus Point using the technique described in Appendix B of WCAP-1 5573, Revision 1. The depth profiles were then processed for corrections in accordance with the depth adjustment rules in Section 4.10.4 of WCAP-15573, Revision 1. The adjusted NDE results were corrected for 95 percentile NDE uncertainty using the NDE uncertainty regression parameters in WCAP-15573, Revision 1. The adjusted NDE and adjusted NDE with uncertainty results are listed in Table 7.

The location of the SCI were very close to the top of tubesheet elevation, within the WEXTEX expansion transition region, and in the center bundle region where the largest tube scale buildup existed prior to chemical cleaning.

The 3dPNO structural limit for an SCI is 265 degrees, assuming a 100 percent TW defect, and 73.5 PDA. The 1R14 bounding SCI measured length was 50.9 degrees, and adjusted to 181.5 degrees after applying large 95 percent NDE uncertainties. This length is less than the 265 degree structural limit under the very conservative assumption that the indication is uniformly TW. Therefore, structural integrity was satisfied at EOC 14.

The largest maximum Plus Point voltage was 0.52 volt, much less than the 1.31 volt threshold for leak testing of circumferential ODSCC in transitions as documented in EPRI Report 1007904. Based on this small voltage, no SLB leakage should be postulated for this degradation at EOC 14. Maximum depth measurements are not 1-12 PG&E Letter DCL-07-106 deemed reliable for these low voltage circumferential indications due to difficulties in sizing low voltage circumferential indications.

Operational Assessment As shown in Table 7, 15 of the 17 WEXTEX transition circumferential ODSCC indications were detectable in the prior outage (1 R1 3) data based on a lookup analysis, indicating very slow growth rates. There are 36 DCPP Units 1 and 2 growth rate data points for WEXTEX transition circumferential ODSCC using the WCAP-1 5573, Revision 1, sizing techniques. The as-found maximum voltages of this data set are all less than 0.5 volt, so depth sizing may not be reliable at these small voltages. Nonetheless, the 95 percentile growth rates per EFPY (based on the empirical distribution function of the median rank fraction) for these data sets are 27 degrees, 33 percent MD, 23 percent AD, and 0.20 volt.

Assuming the same AD detection thresholds as for TSP circumferential ODSCC (35 percent) and a growth rate of 23 percent/EFPY, the projected EOC 15 AD would be 72 percent, less than the 73.5 PDA structural limit. Alternatively, assuming the worst case length of an undetected circumferential indication is equal to the longest indication detected in 1R14 (51 degrees), the projected EOC 15 length assuming a growth rate of 27 degrees/EFPY would be 95 degrees, much less than the 265 degree structural limit.

Because MD measurements in low voltage circumferential indications are not realistic due to difficulties in sizing circumferential indications below about 0.5 volt, maximum voltage is applied for determining leakage integrity at EOC 15 conditions. Assuming the worst case.maximum voltage of an undetected circumferential indication is equal to the maximum voltage detected in 1R14 (0.52 volt), the projected EOC 15 voltage would be 0.85 volt, much less than the 1.31 volts threshold for leak testing of circumferential ODSCC in transitions as documented in EPRI Report 1007904.

Based on the 100 percent Plus Point inspection of the hot leg WEXTEX region, observations of'small numbers of circumferential indications, very small growth rates, and large structural margin, there is a low probability that ODSCC circumferential indications located in the WEXTEX transition zone will challenge the 3dPNO structural integrity performance criteria through EOC 15. Likewise, based on the small maximum voltages associated with circumferential ODSCC indications located in the WEXTEX transition zone, along with very small voltage growth rates, there is a low probability that circumferential ODSCC indications would grow TW in a cycle, and no leakage should be postulated in a faulted SG following a SLB at EOC 15.

1-13 PG&E Letter DCL-07-106 4.4 Cold Leg Thinning (Active)

Condition Monitoring Cold Leg Thinning (CLT) indications at cold leg TSP intersections are detected by bobbin probes, applying EPRI ETSS 96001.1, as part of the 100 percent full-length bobbin inspection. In outage inspections prior to 1R12 and 2R12, CLT indications were sized by bobbin (phase based depth sizing) also using EPRI ETSS 96001.1, and CLT indications were plugged if bobbin indicated a depth greater than or equal to 40 percent TW.

PG&E and Westinghouse had determined that field indications sized by phase angle analysis were found to have deep indicated depths for low voltage indications, resulting in unnecessary tube plugging of low voltage CLT indications. Therefore, a project was undertaken to develop improved bobbin coil sizing techniques to support tube repair decisions, and to develop burst correlations to support tube integrity analyses for CLT indications in Westinghouse Model 51 SGs. The initial work was documented in Westinghouse Report SG-SGDA-02-41, "Cold Leg Thinning Database for Tube Integrity Assessments and NDE Depth Sizing," dated October 31, 2002. In addition, to support implementation of the improved sizing techniques, a performance demonstration was conducted in 2004 to incorporate analyst uncertainty into the correlations, and the results were documented in Westinghouse report SG-SGDA-04-17, "Diablo Canyon Performance Test Based NDE Sizing Uncertainties for Cold Leg Thinning Indications,"

dated April 15, 2004. The performance tests were conducted by 14 NDE analyst teams based upon blind analyses of 201 cold leg thinning samples that included noise additions that applied DCPP noise data to the laboratory simulations of cold leg thinning indications.

Report SG-SGDA-04-17 concluded that amplitude sizing of CLT indications is appropriate to establish the percent TW, with 4.5 volts as the upper limit for amplitude sizing. Above 4.5 volts, phase sizing is used to establish the percent TW. The 4.5 volts cutoff superseded the preliminary recommended cutoff of 1.9 volts provided in report SG-SGDA-02-41 based on the conclusion that amplitude sizing is more reliable than phase sizing below 4.5 volts for indications with high noise levels.

In 1R14, this new CLT sizing technique was again used, in conjunction with the previously established repair limit of 40 percent TW.

The 1R14 CLT inspection program consisted of the following:

New bobbin TSP indications at any cold leg support elevation within 8 tubes in from the periphery were inspected by Plus Point to identify potential new CLT indications.

Cold leg bobbin indications at wedge locations were Plus Point inspected to verify the absence of ODSCC.

1-14 PG&E Letter DCL-07-106 An augmented Plus Point examination program of repeat CLT indications was also implemented. As discussed in PG&E letter DCL-07-068 dated July 9, 2007, in response to NRC request for additional information and based on the 2R13 experience of ding axial ODSCC in the cold leg, an augmented Plus Point sample inspection of repeat CLT indications was performed in 1 R14 to verify the absence of ODSCC coincident with CLT. The sample was biased to repeat CLT indications greater than 1.5 volts that had not been Plus Point inspected during the current inspection period.

Of the 161 inservice Unit 1 CLT indications prior to the 1R14 inspections, 107 had not been inspected during the current inspection period. Of these 107 indications, 16 were greater than 1.5 volts, and were selected for inspection. In addition, it was determined that two repeat CLT indications had never been Plus'Point inspected, and these were also selected for Plus Point inspection in 1 R14. Lastly, all CLT indications greater than or equal to 40 percent TW were Plus Point inspected. None of these examinations detected any indications of SCC, confirming that ODSCC and CLT are not occurring in the same area of the tube bundle. It should also be noted that cold leg TSP ODSCC has never been confirmed by Plus Point at DCPP Unit 1 through 1R14 inspection results.

In 1 R14, 171 CLT indications were detected and sized by bobbin, of which one was greater than or equal to 40 percent and were plugged. All indications were limited from 1C and 2C TSPs. No indications exceeded the 4.5 volts cutoff, so all indications were sized by amplitude analysis.

The deepest indication identified in 1 R14 was 45 percent TW. Applying the regression equation from SG-SGDA-04-1 7 to correct the NDE measurement to the actual depth for 95 percent NDE uncertainty based on the analyst performance test

{%TWActuaj = (%TWMeasured*l.09 + 7.51) + (1.64* standard deviation of 5.73)}, results in a CLT flaw of 66 percent. Applying the lower 95 percent CLT burst correlation from Figure 8-7 of SG-SGDA-02-41 (correlation of burst pressure with actual MD, where actual depth conservatively obtained from the NDE sizing correlation with application of the 95 percent uncertainty on the NDE measurement) yields a CLT burst pressure of 7358 pounds per square inch (psi), much greater than the 3367 psi burst pressure margin requirement for 1.4dPSLB, where SLB differential pressure is 2405 psi.

Therefore, the structural integrity performance criteria were satisfied for this bounding indication at EOC 14. Applying the lower 95 percent CLT ligament tearing correlation from Figure 8-16 of SG-SGDA-02-41 (correlation of ligament tearing pressure with actual MD, where actual depth conservatively obtained from the NDE sizing correlation with application of the 95 percent uncertainty on the NDE measurement) yields a CLT ligament tearing pressure of 6406 psi, much greater than the 2405 psi SLB differential pressure and 3367 psi burst pressure margin requirement. Therefore, no SLB leakage is postulated for this bounding indication at EOC 14.

1-15 PG&E Letter DCL-07-106 Operational Assessment Eleven new CLT indications were detected in 1 R14. All were detectable in the prior outage lookup data and were added to the growth distribution. NDE uncertainties were applied to estimate the mean actual depth for both the 1R13 and 1R14 indications prior to calculating the growth rates for the cycle, using the mean regression equation. One hundred seventy one indications are in the Cycle 14 growth distribution, and the 95 percentile growth rate is 4.02 percent TW per EFPY (based on the empirical distribution function of the median rank fraction).

The largest beginning of cycle flaw left in service (39 percent), corrected for 95 percent NDE uncertainty, plus 4.02 percent/EFPY growth rate, results in a projected EOC 15 flaw size of 66 percent. Applying the lower 95 percent CLT burst correlation yields a CLT burst pressure of 7358 psi, much greater than the 3367 psi burst pressure margin requirement. Therefore, the structural integrity performance criteria are satisfied for this bounding indication at EOC 15. Applying the lower 95 percent CLT ligament tearing correlation yields a CLT ligament tearing pressure of 6407 psi, much greater than the 2405 psi SLB differential pressure and 3367 psi burst pressure margin requirement.

Therefore, no SLB leakage is postulated for this bounding indication at EOC 15.

4.5 Antivibration Bar Wear (Active)

Condition Monitoring AVB wear indications are detected by bobbin probes during the 100 percent full-length bobbin inspection. AVB wear indications are sized by bobbin using EPRI ETSS 96004.1. AVB wear indications are plugged if bobbin indicates a depth greater than or equal to 40 percent TW. The AVB wear repair limit of 40 percent allows for NDE uncertainty and flaw growth progression.

In 1R14, the bobbin coil inspection identified 336 AVB wear indications, of which 3 were greater than or equal to 40 percent and plugged. The deepest indication identified in 1R14 was 44 percent TW in a row 39 tube.

The 3dPNO structural limit for the worst case tube with AVB wear is 71 percent for Row 16 and higher, and 65 percent for Row 15 and lower. The majority of AVB wear in 1 R14 is in greater than Row 15 tubes; only 5 indications were in less than or equal to row 15 tubes. Since the limiting indication is 1R14 was in row 39, a structural limit of 71 percent is applied.

In accordance with EPRI ETSS 96004.1, sizing of AVB wear with bobbin coil has a mean NDE regression correlation equal to 0.97* percent TW + 3.49 percent, with a standard error of 4.49 percent. The total standard error (analyst plus technique) can be accounted for by multiplying the technique error (4.49 percent) by 1.12 per the EPRI SG Integrity Assessment Guidelines, Revision 2. This 1.12 factor assumes that the analyst 1-16 PG&E Letter DCL-07-106 error is 50 percent of the technique error. Therefore, the limiting flaw detected at 1 R14 (44 percent) correlates to a 95/50 confidence value of 54 percent [(0.97*44 + 3.39) +

(4.49*1.12*1.645)], which is less than the AVB wear structural limit of 71 percent.

Therefore, the structural integrity performance criterion was satisfied for this bounding indication at EOC 14. Because the AVB wear depths were too shallow to consider ligament tearing (pop through), no leakage is postulated in a faulted SG following a SLB at EOC 14.

Operational Assessment Forty-four new AVB wear indications were detected in 1 R14, and all were detectable in the prior outage lookup data and were added to the growth distribution. As a result, 336 indications are in the Cycle 14 growth distribution, and the 95 percentile growth rate is 5.76 percent per EFPY (based on the empirical distribution function of the median rank fraction).

The largest beginning of cycle flaw left in service (39 percent), corrected for 95 percent NDE uncertainty, plus 5.76 percent/EFPY growth rate, results in a projected EOC 15 flaw size of 59 percent. This value is less than the AVB wear structural limit of 71 percent, thereby meeting both structural and leakage integrity.

In conclusion, no AVB wear indications are expected to challenge structural integrity performance criteria through EOC 15. In addition, no leakage from AVB wear indications should be postulated in a faulted SG following a SLB at EOC 15 due to the extremely low probability that the projected AVB wear indication would tear ligaments and pop through at the postulated depth.

4.6 Axial ODSCC at Top of Tubesheet Region and Sludge Pile (Active)

Axial ODSCC at the hot leg top of tube sheet (TTS) is typically related to sludge pile accumulation at the TTS, and was identified for the first time as an active degradation mechanism during the 1R13 inspection (twelve indications). A large sludge pile height does not exist at DCPP Units 1 and 2, due to periodic sludge lancing cleanings.

Chemical cleaning was performed in 1R12 and 2R12 to further reduce accumulated sludge at the TTS. However, some degradation may have initiated prior to chemical cleaning, and has progressed slowly to the point of detection.

The Plus Point coil can reliably detect axial ODSCC at the TTS per ETSS 21409.1. In addition, the bobbin coil is capable of detecting axial ODSCC at the TTS per ETSS 96008.1.

Condition Monitoring The mechanism was again detected in the I R1 4 inspection near the TTS region (three indications). Table 8 provides the data for these indications. The affected tubes were 1-17 PG&E Letter DCL-07-106 located in the center of the tube bundle where most of the sludge accumulates. Two indications in SG 1-4 were located within the WEXTEX transition, and one indication in SG 1-1 was located about 1.3 inches above the TTS. The SG 1-1 indication was detectable by bobbin. The location of this indication above the TTS may be attributed to the height of the pre-chemical cleaning sludge pile. In 1R13, a similar indication in SG 1-1 was detected about 1.8 inch above the TTS.

The axial ODSCC indications were not significant, relative to length, depth or voltage.

None of the indications were detectable by bobbin production analysis. The largest peak Plus Point voltage was 0.12 volts, less than the 0.5 volt threshold screening value for leak and burst testing, and much less than the 1.89 volt threshold for leakage testing, based on Revision 2 of the EPRI In-Situ Pressure Test Guidelines. Therefore, there is significant margin for structural integrity and for SLB leakage integrity.

Plus Point maximum depth and length estimates are provided in Table 8 and are based on application of ETSS 21409.1 phase angle sizing techniques. The deepest reported maximum depth based on phase angle measurements was 53 percent (not including NDE uncertainty), which is not reliable due to the small amplitude of 0.11 volts. Depth estimate from the bobbin coil was 6 percent (based on a re-look evaluation), which supports the conclusion of significant margin for SLB leakage integrity.

The longest length of 0.32 inch is shorter than the 3APNO structural limit of 0.43 inch.

The NDE length is not adjusted for NDE uncertainty for comparison to the structural limit because the limit assumes 100 percent TW penetration the entire length of the degradation.

In conclusion, because the maximum voltages have significant margins to tube integrity threshold values, and indicated lengths have sufficient margin to the structural limit, condition monitoring is satisfied for these indications for both leakage and burst integrity. No SLB leakage should be postulated from this mechanism at EOC 14.

Operational Assessment Lookups of the prior outage Plus Point data were performed to determine the growth rate of the indications. As indicated in. Table 8, two of the indications could be detected and sized in 1R13 data, indicating very small growth rates. The 1R13 depth estimates are not reliable due to the small amplitudes. The length growth rate indicates very little change in the signals as well as the low voltage increase, which is bounded by 0.1 volt/EFPY applied in the prior cycle OA.

In order to project the worst case degraded tube with this degradation at EOC 15, two different methods were utilized. The first is based on the Special Case Arithmetic Strategy of Revision 2 of the EPRI Integrity Assessment Guidelines (IAGL). This approach has been verified versus a series of fully probabilistic analyses that consider the entire degradation population, both detected and undetected in previous 1-18 PG&E Letter DCL-07-106 inspections. Table 8-2 in the IAGL details the steps needed to execute this OA strategy.

Firstly, a BOC depth is estimated using the Plus Point amplitudes obtained during the inspections at DCPP 1R13 and 1R14 (see Table 10) and Figure B-6 in the EPRI Insitu Pressure Testing Guidelines Revision 2. Figure B-6 plots axial ODSCC Plus Point voltage amplitudes versus destructive examination maximum depths for pulled tubes from Westinghouse SGs. Applying the Figure B-6 mean correlation, depth measurements were assigned to the 15 indications and are listed in Table 10, for which the median was determined to be 44.8 percent TW, which is conservatively assumed to be the BOC 15 average depth. The worst case upper 95th percentile EOC 15 length was estimated from the lengths in Table 10 using the "Median Rank Fraction" method shown in Section 5.3.1 of the EPRI SG Integrity Assessment Guidelines, and was determined to be 0.366 inch. Using these sizes combined with a default 9 5 th percentile growth allowance in depth (13.1 percent TW/EFPY from the IAGL), a lower 95th percentile material property value, and an upper 9 5 th percentile burst equation burst equation uncertainty, a conservative estimate of the 0.95 probability at 50 percent confidence worst case burst pressure was calculated to be 4453 psi at EOC 15. This value exceeds the 3AP value of 4419 psi for DCPP Unit 1, therefore structural integrity is satisfied. Additionally, the projected depth (66.15 percent TW) is less than that required to create a leakage path at a SLB pressure differential of 2405 psi, therefore, no SLB leakage is projected at EOC 15.

The second method uses a bobbin coil voltage-based ARC strategy. In order to arrive at a BOC 15 flaw size, the Plus Point voltages for the 1 R1 3 and 1 R14 indications were converted to bobbin coil voltages using the Unit 1 specific bobbin to Plus Point correlation. This correlation is used in ARC methods for assigning bobbin voltages to axial ODSCC detected only by the Plus Point coil, referred to as AONDB. By using this correlation, the voltages were established as shown in Table 10. (Note: None of the subject indications detected in the sludge pile/freespan were detectable by the bobbin coil in production analyses. A re-look of SG 1-1 R21 C45 identified a small bobbin voltage of 0.13 volt. This is less than the 0.51 volt calculated bobbin voltage for this indication, demonstrating the conservatism in this bobbin to Plus Point voltage correlation). The highest of these voltages (0.65) was then adjusted upwards to account for the bobbin coil sizing uncertainties (acquisition and analysis) at the upper 95th level. This further increases the BOC size to 0.78 volts. By adding a conservative upper 95th percentile growth rate for new bobbin indications detected in 1 R14, the EOC flaw size is 1.11 volts. By using Figure 6-10 of the EPRI ODSCC Addendum 6 report (based on freespan burst pressures), an EOC burst pressure of approximately 6000 psi is obtained at a lower 95/90 tolerance limit, which is well above the freespan burst 3AP value of 4419 psi for DCPP Unit 1. Therefore, structural integrity is met for the postulated worst case flaw. In the same manner, a 1.11 volt postulated EOC flaw has a probability of leakage of 0.009 at SLB conditions (from Table 6-6 of EPRI ODSCC Addendum 6 report), which makes leakage very unlikely at EOC 15. If the indication were to leak, the leakage would be negligible at 0.004 gpm at 2405 psi SLB conditions 1-19 PG&E Letter DCL-07-106 (Figure 6-20 of EPRI ODSCC Addendum 6 report). Therefore, no SLB leakage is postulated for this mechanism at EOC 15.

4.7 Volumetric OD Indication at Hot Leg Tube Support Plates (Active)

During 1 R14, four single volumetric indications (SVI) were detected at hot leg dented TSPs. Table 9 provides the bobbin and Plus Point calls at these locations for both 1R14 and 1R13, and the SVI axial lengths and circumferential extents from Plus Point in 1 R14. There is no quantified sizing technique for volumetric indications at hot leg TSP intersections. The SVI short lengths (less than 0.25 inches) and short circumferential extents (less than 70 degrees) are indicative of volumetric indications.

Three of the four TSPs had a bobbin distorted OD support signal (DOS) in 1 R14 and prior inspections, required Plus Point inspections in support of voltage-based ARC requirements, and had been left in service under voltage-based ARC for several cycles as axial ODSCC. These four indications were plugged in 1R14 because volumetric indications are not acceptable for continued service under voltage-based ARC.

The fourth indication did not have a bobbin indication, and was inspected by Plus Point in 1 R14 because of the associated greater than 2 volt dented TSP, in support of PWSCC ARC requirements.

A small number of volumetric indications at TSPs have been detected at DCPP~in prior inspections. The SVI calls may be attributed to closely spaced axial ODSCC. A previous DCPP Unit 1 tube pull destructive examination identified very small volumetric degradation (cellular corrosion) at a hot leg TSP intersection in 1 R1 2.

Condition Monitoring The SVI indications were not significant relative to voltage amplitude. The indications were confined to the TSP crevice. The largest peak Plus Point voltage was 0.32 volts, less than the 0.5 volt threshold screening value for leak and burst testing, based on Revision 2 of the EPRI In-Situ Pressure Test Guidelines. The bobbin DOS voltages are less than 2.0 volts (the bobbin coil response reflects an averaging of the OD degradation within the TSP), which is less than the 2.0 volt repair limit for voltage-based ARC and much less than the approximate 9 volt structural limit applied for axial ODSCC under voltage-based ARC. The small bobbin and Plus Point voltages demonstrate that there is significant margin for SLB leakage and burst integrity. As such, condition monitoring is satisfied for these indications for both leakage and burst integrity. No SLB leakage should be postulated at EOC 14.

Operational Assessment Bobbin indications at dented TSPs require Plus Point inspection in support of voltage-based ARC to confirm that the indications are axial ODSCC. In addition, greater than 2 volt dented TSPs at lower hot leg TSP elevations require Plus Point 1-20 PG&E Letter DCL-07-106 inspection in support of PWSCC ARC. Plus Point inspections at TSPs reduce the likelihood of undetected volumetric indications. Therefore, it is unlikely that significant volumetric indications at dented TSPs were undetected in 1R14.

The SVI calls may be attributed to closely spaced axial ODSCC. Treating these small volumetric indications as axial indications is conservative for integrity assessment purposes. The TW structural limit for-axial indications confined to the TSP is about 0.54 inch at 1.4dPSLB differential pressure. Assuming the largest undetected indication is bounded by the longest SVI detected in 1 R14 (0.24 inch), and adding a conservative 95 percentile growth rate of 0.12 inch/EFPY (default value per Revision 2 of the EPRI SG IAGL), the projected EOC 15 length would be bounded by about 0.44 inch, which is less than the TW structural limit. As such, no volumetric indications are expected to challenge structural integrity performance criteria through EOC 15. In addition, no leakage should be postulated in a faulted SG following a SLB at EGC 15 due to the extremely low probability that volumetric indications would tear ligaments and pop through.

4.8 Tube Support Plate (TSP) Ligament Thinning/Cracking (Active)

Starting in 1 R8 and 2R8, PG&E implemented an inspection program to detect degradation of SGs at TSPs. A summary of this program was reported to the NRC in response to GL 97-06 (PG&E Letter DCL-98-046, "90-Day Response to NRC Generic Letter 97-06, 'Degradation of Steam Generator Internals'," dated March 27, 1998).

Visual inspections performed in 1 R8 confirmed several missing TSP ligaments.

Westinghouse has concluded that the missing TSP ligaments are related to TSP drilled hole manufacturing anomalies. The TSP manufacturing practices employed at the time that the DCPP steam generators were produced used a stacked drilling procedure.

Several TSPs were clamped together and drilled simultaneously. A review of the eddy current suspect ligament crack (SLC) locations indicates distinct location patterns, indicative of manufacturing anomalies of the automatic drilling equipment.

Condition Monitoring The 1 R14 eddy current inspection program consisted of several steps: 100 percent bobbin inspection to detect SLC at TSPs; Plus Point inspection of preexisting Plus Point confirmed indications (referred to as baseline indications); and Plus Point inspection of newly detected bobbin SLC indications. Plus Point indications are characterized as either single indication ligament cracks (LIC), or indications exhibiting a missing TSP ligament, referred to as ligament gaps (LIG). LIG indications are further assessed using Plus Point probe data to determine the gap extent.

Only missing TSP ligaments are a threat to tube integrity, as a gap could permit a tube burst under normal operating conditions, assuming tube cracking coincident with the location of the gap.

1-21

I' PG&E Letter DCL-07-106 Axial PWSCC indications or axial ODSCC indications that have a LIC or LIG indication at the same TSP are required to be plugged due to PWSCC ARC and ODSCC ARC exclusion criteria.

In 1R14, Plus Point confirmed all of the baseline ligament indications. In addition, Plus Point confirmed 21 new indications (3 LIG and 18 LIC indications). Thus, a total of 320 indications were detected, 157 LIC and 163 LIG. 28 of the indications were at the same TSP. Thus, a total of 306 TSPs were identified to have indications.

The largest measured LIG gap was 120 degrees. This largest gap bounds the combined gap for the TSP with two LIG indications (20 and 23), assuming that the gaps were connected. This bounding gap is less than the 146 degree threshold gap for preventive tube repair. As such, no tube plugging was required as a consequence of TSP ligament indications with large gaps. However, two LIG indications were plugged due to axial ODSCC indications at the same TSP. The gaps were not coincident with the indications.

Operational Assessment The preservice inspection (PSI) data and prior outage (1 R13) data were reviewed for the new indications. 17 of the 21 new indications were traceable to the 1 R13 bobbin data, demonstrating negligible change over Cycle 14. None of the new indications were traceable to PSI bobbin data.

For the 152 repeat LIG indications, the largest gap was 120 degrees. Repeat gaps were compared to the prior outage gap measurements, showing negligible change. For the 3 new LIG indications, the gaps were 32, 27 and 16 degrees. These new LIG indications were traceable to 1 R1 3 bobbin data based on a lookup. None of the new LIG indications had prior Plus Point inspection data, so a quantitative gap change assessment cannot be made.

The slow progression of ligament gaps indicates an insignificant change in the material condition of the TSPs. It is expected that the gap sizes of repeat and new LIG indications will not extend beyond the 146 degree threshold gap for tube repair at EOC 15.

4.9 Assessment of Installed Hardware for Leakage During Normal and SLB Conditions DCPP Unit 1 has used various types of tube plugs over the course of the previous outages. These include rolled, ribbed, welded, and sentinel plugs. In addition, two different vendors, Westinghouse and AREVA, were contracted during different outages to install their version of tube plugs. Mechanically installed tube plugs are considered leak limiting, and therefore there exists the potential for minor leakage past the tube plug and into the out-of-service tube. However, primary to secondary leakage is not 1-22 PG&E Letter DCL-07-106 probable unless the out-of-service tube has a TW defect or resides in a tube remnant.

SG 1-1 has one tube remnant and SG 1-2 has six tube remnants. Tube remnants are tubes that have been cut and removed for destructive examination. For each of these seven tubes, the hot leg tubesheet hole is plugged with a weld plug, and the cold leg tube portion is plugged with a mechanical plug. Since the mechanical plugs are leak limiting, with an open tube remnant, it is possible that some very small leakage past the plug could escape to the secondary side.

Most of the plugged tubes are repaired with AREVA rolled plugs. The qualification testing for the AREVA repair hardware included leak testing at both room temperature and operating temperature. A review of the qualification report shows that a leak rate of 3.2 x 10-6 gpm (leakage adjusted to room temperature conditions) per plug would bound the results for all leak tests performed and is applicable to both accident and normal operating conditions.

A very conservative estimate of leakage in the four SGs can be made by assuming all mechanical plugs leak at the bounding rate (welded plugs do not leak). This would result in the following NOP leakage in gpd for each SG during Cycle 15: 2.27 gpd in SG 1-1, 3.10 in SG 1-2, 0.97 gpd in SG 1-3 and 1.77 gpd in SG 1-4. Using the same data, the equivalent SLB leakage in gpm would be: 0.002 gpm in SG 1-1, 0.002 gpm in SG 1-2, 0.001 gpm in SG 1-3, and 0.001 gpm in SG 1-4.

As discussed above, only tubes with either TW cracks or open tube remnants can actually contribute to primary to secondary accident leakage, and therefore the leakage estimates provided above are extremely conservative. As a result, no accident induced leakage is attributed to plug leakage for both CM and OA.

Background

SG tubes in Rows 1 and 2 U-bends were heat treated following one cycle of operation for Unit 2 and two cycles of operation for Unit 1 to relieve stresses and mitigate the potential for PWSCC in this location. One hundred percent of Rows 1 and 2 U-bends have been inspected each refueling outage. Bobbin probes were used in the first refueling outage inspection. Since then, these inspections were conducted with a single coil rotating probe. Starting in 2R7 and 1 R8, a Plus Point probe was used to inspect Rows 1 and 2 U-bends for detection of PWSCC.

PWSCC has been detected in the U-bend region of Row 1 tubes in all Unit 1 and Unit 2 SGs. The majority of Row 1 PWSCC has been axial, with a small number of circumferential. Axial PWSCC has also been detected in Row 2 in SG 1-4 (1R8) and 1-23 PG&E Letter DCL-07-106 SG 2-3 (2R8). Starting in 2R1 I and 1 RI 2, 100 percent of Rows 1 to 10 have been Plus Point inspected. The 2R1 1 inspection included 100 percent inspection to Row 46. No axial PWSCC indications have been detected in greater than Row 3 in these inspections. The last occurrence of Row 1 or 2 U-bend axial and circumferential PWSCC indications in Unit 1 have been 1R8 and 1R10, respectively.

1R14 Inspections In 1R14, 100 percent of Rows 1 and 2 U-bends were Plus Point inspected, applying ETSS 96511.2 technique for detection of PWSCC. No indications were detected. Due to the degradation-free Row 1 and 2 U-bend region for Unit 1 for the last four cycles of operation based on 100 percent Plus Point inspection, PWSCC in Rows 1 and 2 U-bends is not an active damage mechanism.

5.2 Circumferential PWSCC in Row 3 to Row 8 U-Bends (Non-Active)

Background

In 2R1 1, a secondary side pressure test in SG 2-4 identified leakage in the R5C62 U-bend region. Subsequent Plus Point inspection detected several short circumferential crack-like indications on the ID of the Row 5 U-bend, extending from the hot leg tangent point to the cold leg tangent point in the flanks (sides) of the tube wall.

Because industry had never performed extensive high row U-bend inspections with a rotating probe, and this was a first of a kind degradation mechanism in both domestic and foreign plants, a critical area could not be immediately determined to limit the Plus Point inspection scope. As a result, the U-bend Plus Point inspection program was expanded to include 100 percent of the U-bend regions of all rows (Rows 3 through 46) in each SG. A total of 12 tubes were identified to have similar circumferential indications, ranging from Row 3 to Row 10. Each SG had at least one indication. The indications were located on the flanks of the tube. Video probe inspections confirmed the presence of circumferential ID cracking. The tubes were in-situ leak and proof tested, and only R5C62 exhibited leakage at SLB differential pressure (about 0.003 gpm at room temp).

The root cause of the indications was attributable to circumferential PWSCC due to high residual stresses inherent to the tube bending process, as documented in a formal root cause report issued by PG&E.

Following the 2R1 1 experience, the Westinghouse Owner's Group (WOG) issued a report on September 15, 2003, which defined a critical area for this damage mechanism and provided inspection and expansion recommendations for similar Model 51 SGs.

The WOG report demonstrates that U-bend circumferential flaw development is related to longitudinal residual stress, which is dependent on row (bend radius). Based on finite element analysis, longitudinal stress is reduced by a factor of four from Row 5 to Row 10, and a factor of two from Row 10 to Row 15. Figure 10 of the WOG report plots 1-24 PG&E Letter DCL-07-106 longitudinal strain as a function of row, and shows similar results (e.g., longitudinal strain, and hence stress, is reduced by a factor of about two from Rows 9 and 10 to Row 16).

All Westinghouse SGs with Alloy 600 mill annealed tubing have completed the initial U-bend inspections per the WOG inspection guidelines, and several have completed subsequent inspections. For plants that had circumferential indications detected in the first inspection, the number of indications in their second inspection was dramatically reduced, illustrating the Plus Point inspection transient associated with this damage mechanism, as well as a low initiation and growth rate.

For DCPP Unit 2, the first time inspections in 2R1 1 identified twelve tubes with circumferential PWSCC, the second time inspections in 2R12 identified two tubes with circumferential PWSCC, and the third inspections in 2R13 identified three tubes with circumferential PWSCC. Most of the indications were in Rows 5 and 6. The small number of 2R1 2 and 2R1 3 indications were of relatively small voltage, and were detectable upon relook of prior outage data, and thus had initiated before 2R1 1.

For DCPP Unit 1, the first time inspections in 1 R1 2 identified 85 tubes with circumferential PWSCC indications, with Row 8 being the highest row affected and most of the indications occurred in Rows 5 and 6. The second time inspections in 1 R1 3 did not find any indications. Of the 1 R1 2 indications, a total of nine tubes with U-bend circumferential PWSCC indications had Plus Point voltages in excess of 1.73 volts, and were in-situ pressure tested. Four of the tubes leaked slightly at pressures in excess of 3750 psi, well above SLB pressure of 2405 psi. At 3APNO, no burst occurred and very small leak rates were measured. Based on these 1R12 results, no SLB accident-induced leakage was attributed to U-bend circumferential PWSCC, and structural margins were maintained. It was believed that the SG 1-4 prior cycle operational leakage of 1 gpd may have been due to leakage from one or all of these 4 tubes even though no leakage was identified in the in-situ tests at normal operating pressure and SLB differential pressures.

For PWSCC data limited to DCPP SGs, Unit 1 is limited to Row 8 and Unit 2 is limited to Row 10. For Model 51 SG data not including DCPP, PWSCC is limited to Row 9, consistent with DCPP experience. The peak voltages of the DCPP indications also decrease with increasing row. The combination of smaller numbers and smaller voltages with increasing row validates the information on Figure 10 of the WOG report which shows decreasing strain with increasing row.

1R14 Inspections The 1 R14 inspection plan consisted of inspection of 20 percent of the Row 3 to Row 8 U-bend region in each SG. As an additional conservative measure, 40 percent of Row 5 and 40 percent of Row 6 U-bend regions were inspected in SG 1-4 because of the historical bias of the degradation to this SG, as discussed below.

1-25 PG&E Letter DCL-07-106 All Plus Point inspections were conducted applying ETSS 96511.2 techniques.

The basis for the examination scope was predicated on Section 3.4.2 of the EPRI Examination Guidelines Revision 6 which states: "If during the previous examination, the damage mechanism within a critical area (CA) was determined to be non-active, then at least 20 percent of the inservice tubes within the CA shall be examined in the previously affected SGs." Because no circumferential PWSCC was detected in the previous 1 R13 examination which consisted of 100 percent Plus Point inspection of Rows 3 to 10 in each SG, then 20 percent of the CA is required to be examined in 1 R14. The CA is defined as Rows 3 to 8 in each SG, consistent with the WOG report definition of the CA.

A larger sampling of SG 1-4 was conducted based on prior degradation experience. In 1 R12, U-bend circumferential PWSCC was detected in only SG 1-3 and SG 1-4, with the vast majority of affected tubes (87 percent) in SG 1-4. In addition, 82 percent of the affected tubes in SG 1-4 were confined to Rows 5 and 6. Thus, for 1R14 inspections, the sampling in SG 1-4 Rows 5 and 6 were conservatively increased to 40 percent of the active tubes. Thus, the total inspection sample in SG 1-4 consisted of 25 percent of the active tubes.

Expansion plan criteria were developed and documented in the Degradation Assessment (see Table 1), but implementation was not required.

No PWSCC indications were detected in the 1 R14 U-bend inspections, once again validating that the 1 R1 2 Plus Point inspection results were a transient associated with this damage mechanism.

5.3 Potential Axial PWSCC in High Row U-Bends (Non-active)

Background

Westinghouse WOG evaluation SG-SGDA-03-33, "Generic Evaluation of U-Bend PWSCC Susceptibility for Model 51 SGs with Mill Annealed Alloy 600 Tubing," states that significant ovality could be experienced in large radius bends (Rows 10 and higher) that could have resulted in significant residual stresses in the tubes. These residual stresses could lead to axial PWSCC in large radius U-bends.

Figure 7 of the WOG report provides a plot of total strain percentage by row, combining the effect of longitudinal strain (from WOG report Figure 10 residual bending stresses) and hoop strain (from WOG report Figure 5 ovality data). This figure shows that the average strain in Rows 3 to 7 exceeds the average strain in any higher row, including Rows 13 to 15, and that the average strain in Rows 3 and 4 is greater than Rows 5 to 7.

The WOG report also noted that significant ovalities could be experienced in larger radius (Rows 10 and higher) bends that could have resulted in significant residual stresses in the tubes. These residual stresses could lead to axial PWSCC in large 1-26 PG&E Letter DCL-07-106 radius U-bends. The WOG report provided an initial recommendation for detection of axial PWSCC in large radius bends that included a minimum 20 percent sampling of Rows 12 or 13 to Rows 17 or 18. The basis at that time Was that the inspection of Rows 3 through 10 may not have included the tubes with the largest ovality.

Inspection results were evaluated from the prior examinations of greater than or equal to Row 3 U-bend inspections of Westinghouse 600 MA SGs that started in 2003. No axial PWSCC indications have been reported in inspections at DCPP Units 1 and 2.

For DCPP Unit 1, no degradation was detected in 1 R1 2 (100 percent Plus Point inspection of Row 3 to Row 10 U-bends, plus 20 percent of Rows 13 to 17) nor in 1 R1 3 (100 percent Plus Point inspection of Row 3 to Row 10 U-bends). For DCPP Unit 2, no degradation was detected in 2R1 1 (100 percent Plus Point inspection'of > Row 3 U-bends), in 2R12 (100 percent Plus Point inspection of Row 3 to Row 10 U-bends), nor in 2R13 (100 percent Plus Point inspection of Row 3 to Row 10 U-bends). In other SGs, four small axial PWSCC indications were detected in Rows 3 and 4, and these SGs operate at higher temperatures than DCPP SGs.

The field results suggest that axial PWSCC development may be more complex than the simple relation to ovality or total strain from the fabrication. It is possible that the suppression of ovality using the concave die may lead to a more complex stress field, thus leading to indications being located predominately in the lower rows. Therefore, rather than inspecting greater than Row 10 U-bends, inspection of lower rows is sufficient to find the onset of axial PWSCC. Therefore, the CA for axial PWSCC is defined as Rows 3 to 4 based on a review of Figure 7 of the WOG report, which shows that the average strain in Rows 3 to 4 exceeds the average stain in any higher row, including Rows 13 to 15. Twenty percent of the CA requires inspection in each SG consistent with the requirements in Section 3.4.2 of the EPRI Examination Guidelines Revision 6 for non-active damage mechanisms.

1R14 Inspections In 1 R14, detection of potential axial PWSCC in high row U-bends was accomplished by performing Plus Point inspection of 20 percent of U-bends in Rows 3 to 4 in each SG.

(Note: Plus Point sample inspection of Rows 5 to 8 U-bends was also conducted to detect potential circumferential PWSCC.) No indications were detected in this sample inspection. Also, bobbin did not detect any U-bend signals that are indicative of potential axial cracking and that would require Plus Point inspection. Expansion plan criteria were developed and documented in the Degradation Assessment (see Table 1),

but implementation was not required.

All Plus Point inspections were conducted applying ETSS 96511.2 techniques.

Because no axial PWSCC indications were detected in 1R14, the results once again confirmed that axial PWSCC in high row U-bends in not active.

1-27 PG&E Letter DCL-07-106 5.4 Circumferential PWSCC in Hot Leg WEXTEX Tubesheet Region (Non-Active)

Background

A small number of tubes have been plugged due to circumferential PWSCC in the WEXTEX tubesheet region (10 for DCPP Unit 1 and 15 for DCPP Unit 2). No indications have been detected since 1R12 and 2R10. Circumferential PWSCC indications in the WEXTEX region are not eligible for W* ARC unless they are located below the W* region. Of the 26 PWSCC circumferential indications reported to date at DCPP Units 1 and 2, 18 were located within the expansion transition (within 1 inch of the TTS), with the deepest at about 9 inches below the TTS. Most axial and circumferential PWSCC indications have been reported within 3 inches of the TTS.

PWSCC initiation is likely associated with a localized geometry discontinuity resultant from the tubesheet drilling process. As all tubesheet holes were drilled from the primary face, the frequency of tube hole abnormalities would expect to be increased as the secondary side face of the tubesheet is approached. The DCPP Units 1 and 2 data support this expectation.

Top of tubesheet PWSCC was first reported at DCPP Unit 1 and DCPP Unit 2 in 1 R6 and 2R5, respectively. Circumferential PWSCC was first reported in 2R5 and 1 R7.

The number of new PWSCC indications has shown a declining trend over time, possibly attributed to zinc injection in the reactor coolant system which started in Cycle 9. The hot leg top of tubesheet region shot peening performed in I R5 and 2R5 may also be a contributing factor for the declining trend of PWSCC initiation at the top of tubesheet.

1R14 Inspections One hundred percent of the hot leg top of tubesheet WEXTEX region was inspected with Plus Point, applying ETSS 20510.1 techniques. The inspection extent was

+2/-8 inches relative to the top of tubesheet. No circumferential PWSCC was detected in this exam. Since there has been no circumferential PWSCC detected in the WEXTEX tubesheet region since 1 R1 2, this damage mechanism is non-active.

5.5 Free Span ODSCC at Dinged Locations (Non-Active)

Background

Axial ODSCC at free span dings and circumferential ODSCC at free span "paired" dings are potential degradation mechanisms for DCPP Unit 1.

Axial ODSCC at free span dings has been reported in several original Westinghouse designed SGs. In DCPP Unit 2 in 2R1 3, two small axial ODSCC indications were reported by bobbin as ding with indication (DNI) at small voltage free span dings (less 1-28 PG&E Letter DCL-07-106 than 5 volts) located in the cold leg lower elevations, and confirmed by Plus Point as axial ODSCC. This was a new degradation mechanism for DCPP. Prior to 2R1 3, no occurrences of stress corrosion cracking at free span dings had been observed at DCPP Units 1 and 2, based on Plus Point sampling of free span dings every outage starting in 2R7 andl R8. Plus Point sample inspections of greater than 2 volts dings were routinely performed starting in 2R7 and 1 R8. Starting with 2R1 1 and 1 R12, the bobbin coil was credited for detection of cracking in less than or equal to 5 volts dings (applying EPRI ETSS 24013.1) and Plus Point inspections were focused on greater than 5 volts dings.

PG&E also evaluated the potential for circumferential ODSCC at free span dings based on industry experience in original Westinghouse designed SGs. PG&E determined that a total of four small circumferential indications at free span dings were reported in two plants. In all cases, the ding orientation was circumferential, and limited to dings that occur in pairs (termed paired dings). Paired dings result from the tube being rotated out of plane while engaged with a TSP during tube insertion, such that the paired dings would be located about 0.75 inch from each other and on opposite sides of the tubes.

PG&E reviewed the industry data for applicability to DCPP Unit 1 and 2, and has concluded that paired dings may exist at both units. Prior to 1R14, the axial separation distances of DCPP Unit 1 ding indications were reviewed and it was determined that 109 free spans had dings located about 0.75 inch apart (plus or minus 0.25 inch).

Sixty-nine of these 109 free spans had a prior Plus Point examination during at least one of the past five inspections, with no ODSCC detected. This is a sufficient sample to conclude that circumferential ODSCC in free span paired dings is not an active damage mechanism at DCPP Unit 1.

1R14 Inspections for Detection of Axial ODSCC Twenty percent of greater than 5 volt free span dings were inspected by Plus Point applying EPRI ETSS 21409.1. As discussed in PG&E Letter DCL-06-129, "Special Report 06 180 Day Report for Steam Generator Technical Specification Task Force (TSTF) 449 for Diablo Canyon Power Plant Unit 2 Thirteenth Refueling Outage,"

dated November 17, 2006, the dings were biased to the cold leg straight sections, based on the experience in 2R1 3 of cold leg ding ODSCC and the fact that previous Plus Point inspections have been biased toward the hot leg. There are approximately 380 greater than 5 volt free span dings in DCPP Unit 1.

For less than or equal to 5 volt dings, the bobbin coil was credited for detection of ODSCC applying EPRI ETSS 24013.1. In 1R14, no potential degradation at free span dings was reported by bobbin.

In addition, 20 percent of greater than or equal to 2 volt dings that are coincident with AVB structures in the U-bend region were Plus Point inspected, to address industry experience of the potential masking effects of AVBs on bobbin coil flaw detection.

1-29 PG&E Letter DCL-07-106 Note: In 1R12, 100 percent of greater than or equal to 2 volt dings that are coincident with AVB structures were Plus Point inspected.

Expansion plan criteria were developed and documented in the Degradation Assessment (see Table 1), but implementation was not required.

No axial ODSCC at free span dings was detected in the 1 R14 inspection program.

1R14 Inspections for Detection of Circumferential ODSCC Circumferential ODSCC was treated as a potential degradation mechanism for the first time in 1R14. As discussed in PG&E Letter DCL-06-129 dated November 17, 2006, PG&E's ding inspection plan for 1R14 was revised to require Plus Point inspection of 100 percent of greater than 2 volt paired dings that had never been inspected in the current inspection period, to be consistent with the DCPP TS 5.5.9 requirement to inspect 100 percent of potential damage mechanisms within the 60 EFPM period.

There are 268 paired dings in Unit 1, and 121 were programmed for Plus Point inspection in 1 R14 to meet the requirement described above. The vast majority (117) of the 121 dings inspected were less than 5 volts, which represented about 6 percent of the less than 5 volt ding population in Unit 1.

Expansion plan criteria were developed and documented in the Degradation Assessment (see Table 1), but implementation was not required.

No circumferential ODSCC at free span paired dings was detected in the 1 R14 inspection program.

5.6 ODSCC Mixed Mode Indications at Dented TSP Intersections (Non-Active)

Background

If a dented TSP intersection contains an axial ODSCC indication and a circumferential indication (either ODSCC or PWSCC), this degradation is termed ODSCC mixed mode indication. Since axial ODSCC indications detected by bobbin at dented locations must be inspected with Plus Point as required by voltage-based ARC inspection criteria, 100 percent of the susceptible population of ODSCC mixed mode indications would be detected at each inspection. Two ODSCC mixed mode indications were detected in 1 R12 (which were determined to be non-interacting), and one indication was detected in 1R1l1.

1R14 Inspections 100 percent of bobbin distorted OD indications (DOS) at dented TSP locations were inspected by Plus Point, as required by voltage-based ARC inspection criteria. No ODSCC mixed mode indications were detected.

1-30 PG&E Letter DCL-07-106 An OA is performed for ODSCC mixed mode indications because this degradation mechanism has increasing potential for occurrence due to the increasing population of TSP axial ODSCC indications returned to service every inspection under ODSCC ARC.

Operational Assessment In Unit 1 Cycle 15, there is a low likelihood of interacting ODSCC mixed mode indications developing that could affect leakage or burst margins of the axial ODSCC flaw, based on the following assessment. Potential TSP circumferential cracking should mainly occur in greater than 2 volts dents. There have only been two circumferential indications observed at a dent less than 2 volts (one in 1 R1 2 and one in 1 R1 3). Nonetheless, potential circumferential indications at all dent sizes are considered. There were 483 intersections returned to service following 1R14 that contained Plus Point confirmed axial ODSCC at dented intersections. Three hundred twenty seven of these intersections contained dents less than or equal to 2.0 volts and 156 of these intersections contained dents greater than 2.0 volts. All of these intersections were inspected by Plus Point to verify that no axial PWSCC or circumferential indications were detectable. Of these ODSCC indications at dented TSPs that were returned to service, the largest bobbin amplitude was 1.80 volts with a maximum Plus Point amplitude of 0.40 volts. The largest Plus Point amplitude from ODSCC indications returned to service at dented TSPs was 1.18 volts with a corresponding bobbin amplitude of 1.40 volts.

The upper 95 percent growth rate per EFPY for repeat axial ODSCC indications in Cycle 14 is about 0.2 volt/EFPY. Adding this growth rate to the largest bobbin indication left in service at a dented TSP (1.80 volts) results in an EOC 15 flaw of about 2.13 volts.

Assuming the largest projected EOC 15 TSP circumferential indication (56 percent AD) interacts with a projected EOC 15 axial ODSCC indication of 2.13 volts:

The axial ODSCC indication burst margin would not be affected because the 56 percent circumferential AD is less than the 75 percent AD threshold for mixed mode burst affects developed in WCAP-1 5573, Revision 1. In addition, a 2.13 bobbin volt ODSCC indication has a large margin against burst compared to the approximate 9 volts structural limit.

The axial ODSCC indication SLB leak rate margin would not be affected because a 2.13 bobbin volt ODSCC indication has a very small probability of leaking as a free span indication, per the ODSCC ARC correlations. In addition, the largest EOC 15 ODSCC Plus Point amplitude at a dented TSP (1.18 volts at EOC 14 for comparison) would be expected to remain below the 2.75 volts typical of a TW indication for axial ODSCC.

1-31 PG&E Letter DCL-07-106 5.7 Secondary Side Integrity and Potential Tube Damage from Loose Parts and Foreign Objects (Non-Active)

In 1R14 (similar to 2R13), there were no SG secondary side maintenance activities. No sludge lancing was performed, no foreign object search and retrieval (FOSAR) inspections were performed, no SG upper internals inspections or repairs were conducted, and the lower (handholes) and upper secondary side manways were not removed.

Revision 2 of the EPRI SG IAGL provides guidance on SG secondary side maintenance, including cleaning and visual inspection activities. PG&E followed the EPRI guidance in developing justifications for not performing secondary side maintenance activities in 1 R14.

A detailed technical justification for not performing sludge lancing was prepared well in advance of the outage, approved by DCPP management, and was documented in the Degradation Assessment. Chemical cleaning was performed in 1R12 and 2R12, in which about 19,000 pounds (Unit 1) and 29,000 pounds (Unit 2) of sludge and scale were removed. The small amount (total 56 pounds) of sludge removed in 1 R1 3 (first outage after chemical cleaning), together with the small numbers of TTS ODSCC detected to date, provided sufficient technical basis for not performing sludge lancing activities in 1R14, which is the final refueling outage before SG replacement in 1R15.

A detailed technical justification for not performing FOSAR inspections was also prepared well in advance of the refueling outage, along with a FOSAR contingency plan that was dependent on the results of the eddy current inspections. The justification addressed the specific EPRI guideline recommendations listed below. The justification was approved by DCPP management and was documented in the Degradation Assessment. The small numbers and declining trend of foreign objects detected in the SGs, combined with the observation that no tube wear attributable to foreign objects has ever been detected by eddy current testing in the DCPP Unit 1 and 2 SGs, provided sufficient basis for deletion of FOSAR activities in 1 R14.

The EPRI guideline requires that FOSAR inspections be performed following each sludge lancing, or any other time that the secondary side handholes are opened for maintenance access. If sludge lancing is not being performed and the secondary side hand holes are not scheduled to be opened, then the decision to perform a scheduled FOSAR during a refueling outage is to be based on a documented evaluation that considers the maximum interval between secondary side visual inspections, and also consider operating experience from all pressurized water reactors. If FOSAR is not

-scheduled to be performed during a refueling outage based on a documented evaluation, a plan to perform a contingency FOSAR in the affected SG(s) during the refueling outage is to be developed. The contingency plan is to consider the results of the primary side eddy current inspections, subsequent potential engineering evaluation 1-32 PG&E Letter DCL-07-106 of possible loose part (PLP) indications, and known foreign objects that could have entered the SGs (e.g., from the feed train).

The EPRI guideline provides the following specific elements (including historical loose parts, wear indications, similar plant inspection results, maintenance activities, and the planned eddy current inspection intervals) that need to be addressed when documenting the maximum interval between secondary side visual inspections.

PG&E's detailed evaluation considered the following elements identified in the guideline, as discussed below.

Location and description of historical loose parts. Unit 1 had no PLP indications in the last two inspections (1 R1 2, 1 R1 3). A loose parts log was created to describe, track and trend loose parts retrieved (or not retrieved) from the DCPP SGs. In general, most of the prior loose parts are associated with DCPP SG upper internals maintenance activities that were initiated in the Units 1 and 2 Fifth Refueling Outages (1 R5/2R5).

The trend for loose parts has declined over the years, coincident with the decline of SG upper internals maintenance activities, which were finally completed in 2R1 1 and 1 R1 2.

The 2004 Self-Assessment of DCPP foreign material exclusion (FME) practices showed that the FME program is in good health and is continuing to improve.

The upper internals maintenance activities included the following:

J-Tube Entrances - Highly localized flow-accelerated corrosion damage was observed at several j-tube/feedring connections. Two types of repairs were implemented:

removal of the damaged area by installation of a larger diameter j-tube attachment, and weld overlay of the original attachment weld. Both remedies were designed for the remaining life of the SGs.

Riser Barrels - Riser barrel erosion caused by j-tube discharge impingement was repaired and further degradation precluded by installation of erosion-resistant Inconel plates.

Feedring - Small defects in the seal welds at plugs closing the original feedring bottom holes (the holes were later replaced by j-tubes) were repaired by welding.

In SG 1-1, base metal repair was done in one small area of the feedring subject to j-tube discharge impingement. Remote visual inspection of backing rings identified potential remnants that could detach in operation, and these remnants were removed in advance of detachment.

Description of those foreign objects with associated wear indications. This element is not applicable to DCPP Unit 1 and 2, as no loose part wear indications have been detected over the life of the plant.

Failure of control and monitoring of foreign objects and loose parts. Based on the larger number of loose parts associated with DCPP SG upper internals maintenance 1-33 PG&E Letter DCL-07-106 activities, it appears that there was a failure of control and monitoring of foreign objects during these activities. Upper internals maintenance was completed in 2R1 1 and 1 R12.

There are no known issues in the feedwater system that would result in loose parts being transported to the SGs.

High flow or susceptible areas. Susceptible tube bundle areas are tubes adjacent to the annulus, due to high flow. The annulus region has been routinely FOSAR inspected every outage, and the vast majority of loose parts have been retrieved from this region. The most recent FOSAR in 2R1 2 and 1 R1 3 identified a few wires of insignificant mass and one magnetic object.

Inspection limitations. Previous FOSAR inspections have been confined to the annulus and tube lane, with several columns selected for in-bundle exams.

Categorization of probable causes, origins, and migration. Most of the loose parts have been due to upper internals secondary side maintenance activities, which were completed in 2R11 and 1 R12.

Trends for foreign objects associated wear. This element is not applicable to DCPP Unit 1 and 2, as no loose part wear indications have been detected over the life of the plant.

Eddy current detectability issues. EPRI SG Examination Guidelines, Revision 6, Section 3.4, states that all peripheral tubes, including tubes adjacent to no-tube lane regions, shall be added to the periodic sample to monitor for loose parts, and that a secondary-side FOSAR examination may be used to meet this requirement. Possible crediting of FOSAR to meet this requirement was added in Revision 6 of the EPRI guideline because it was recognized that the bobbin probe has some detection limitations at the TTS due to the potential masking affects of the expansion transition on some small loose parts. For 1R14, the periodic sampling of the cold leg peripheral tubes was satisfied by 100 percent bobbin inspection as augmented by a special bobbin turbo mix evaluation of 100 percent of the cold leg top of TTS region, in order to detect potential tube degradation that could be missed by the bobbin probe. This is considered satisfactory because: DCPP has a good FME program so there is low probability of having loose parts in the SG; SG upper internals maintenance activities have been terminated after 2R1 1 and 1 R1 2; DCPP has never detected any loose part tube wear; DCPP has performed FOSAR in every prior outage, chemical cleaning eliminated sludge piles; the axial extent of the WEXTEX transition region is small (on the order of % inch), such that bobbin should be able to detect large tube wear indications that are a potential threat to tube integrity; and there are no known un-retrieved foreign objects in the last inspection.

Eddy current inspection intervals. Eddy current inspections are being performed in 1 R14, so eddy current detection capability of potential loose parts and loose part wear is maintained.

1-34 PG&E Letter DCL-07-106 Results of 1R14 Inspections and Data Analysis.

One hundred percent of the bobbin data (low frequency channel) was reviewed for PLP indications by both primary and secondary analysts. In addition, a special in-depth bobbin analysis was performed for PLP indications along the full length of Rows 1 to 3 and the outer 3 peripheral tubes. PLP indications detected by bobbin are required to be inspected with Plus Point. At the hot leg top of tubesheet, Plus Point data was reviewed for PLPs during the 100 percent hot leg TTS Plus Point. inspections. It is noted that there is no EPRI qualified eddy current technique for detection of loose parts.

The techniques used at DCPP are consistent with industry practice and have proven effective in finding loose parts at DCPP and many other sites. Tubes with loose part signals are included on the SSPD which all analysts are required to pass.

Detection of potential loose part wear is accomplished using the bobbin probe (and Plus Point probe where Plus Point inspections are conducted). EPRI ETSS 96004.1 for detection of wear at tube supports and antivibration bars is extended for detection of loose part wear. This detection technique was augmented by a turbo-mix analysis at the cold leg top of tubesheet. Turbo-mix uses a 200/400/100 kHz mix with the support ring and tubesheet expansion suppressed. No percent curve is applied to this mix and any indications detected by this review must be reported to the Lead Analyst and examined with the three coil rotating probe. As discussed in PG&E letter DCL-07-068 in response to NRC questions on the use of turbo-mix, turbo-mix is not an EPRI qualified detection technique for loose part wear. The technique is intended to detect loose part wear, not loose parts. The use of nonqualified techniques, such as the turbo-mix, can sometimes enhance the detection capability of the bobbin probe in regions where rotating probes are not routinely employed. Because the turbo-mix is neither qualified nor required, it is used as best effort diagnostic tool. Industry use of the turbo-mix has demonstrated its ability to detect loose part wear.

No potential loose part signals or tube wear was detected by the eddy current inspections in 1R14, including turbo-mix. As such, the FOSAR contingency plan was not required to be implemented.

Table 1 of Enclosure 2 provides a list of all service induced indications, including location, orientation (if linear), and measured sizes (if available) identified during the Unit 1 fourteenth refueling outage. Table 1 also identifies the tubes that were plugged and provides the reason for tube plugging.

Bobbin indications that were not confirmed by Plus Point are not reportable indications; however, these bobbin indications are included Table 1 for completeness. Historical free span indications that had eddy current signals traceable to preservice inspection data (e.g., manufacturing burnish mark) are not considered as reportable indications and are not included in Table 1.

Table 1 includes measured through-wall depth penetrations of antivibration bar wear and cold leg thinning indications. Enclosure 1 provides estimated measured percent through-wall depth penetrations of non-alternate repair criteria (non-ARC) crack-like indications. Measured percent through-wall depth penetrations of primary water stress corrosion cracking ARC and Tubesheet Transition (Wstar or W*) ARC crack-like indications have been previously submitted to the NRC via letter DCL-07-085, "Results of Steam Generator (SG) Tube Alternate Repair Criteria (ARC) Inspections for Diablo Canyon Power Plant Unit 1 Fourteenth Refueling Outage," dated August 27, 2007.

Detected indications that are located in carbon steel tube support plates (e.g.,

suspected tube support plate ligament indications) are not included in Table-1, as the indications are not contained in the tubing material.
