Section 2 Summary of Conditions Observed Limerick Generating Station, Unit 1 Cycle /Refuel Outage 11 Interval: 2 Period: 3 March 20, 2004 to March 24, 2006

Summary of Conditions Observed As a result of the examinations performed during the Limerick Generating Station Unit 1, refuel outage 11, there were no new indications requiring flaw evaluations that are reportable to the NRC, either by ASME Section XI requirements or BWRVIP protocol. Numerous other conditions were recorded and subsequent examinations and/or evaluations determined all conditions to be either non-relevant or geometric in nature.

The following is a summary of the significant indications identified during the inspections.

Core Shroud UT inspections were performed on welds HI, H2, H3, H4, H5, H6, H7, V15, V16, V17, and VI8. During these inspections several flaws were identified in each weld. No cracking was seen at welds V15, V16, and H7.

Structural margin evaluations were performed and documented in ECR LG 06-00135. The evaluation is attached to this report as'required by the BWRVIP.

ST-4-041-950-1 ISI Pressure Test For All Class I Systems and Some Class 2 Systems- The VT-2 inspections identified minor 0-ring leakage from the CRDS 22-27, 46-23, 34-55, and 24-49.

Quadrant 2 panel IB in the Suppression Pool Submerged Space- A pit was identified which had 80 to 122 mils metal loss. A repair coating was applied to the pit.'.

DCA-104-X-13A Penetration Anchor- Somne d6gradation was identified around the penetration. An evaluation concluded that there was no structural degradation that would compromise the design margin of the penetration anchor.

EBB-109-H009 Rigid Restraint- A loose nut was identified, the nut was tightened per A1556232.

GBC-101 -HI 84 Rigid Restraint- The inspection identified improper clearance, A1557953 concluded the condition was acceptable.

Shroud Head Bolts The Ultrasonic examination of the Shroud Head Hold Down Bolts revealed nine bolts that had indications of cracking. The nine bolts were removed and ECR 01-00903 ShroudHeadBolt Reduction was completed which allowed the number of required shroud head bolts to be reduced from 48 bolts to 34 bolts. Two bolts were moved to a new location so there would not be any two locations next to each other without a bolt. The present locations of the Shroud Head Hold Down Bolts are listed below. There was no ANII involvement in the Shroud Head Bolt examinations.

' Evaluation ofthe Limerick Generating Station Unit'l Core Shroud Welds (HI, H2, H3, H4, H5, H6, H7, V1 7, V18) for One Operating Cycle

Dear Ms. Karasek,

Structural Integrity Associates (SI) has performed an evaluation of the UT inspection results for welds HI, H2, H3, H4, H5, H6, H7, V17, V18 of the Limerick Unit 1 core shroud obtained during the current on-going March 2006 r'efueling outage. The evaluations summarized in this report determine the safety factors for the welds at the end of the next operating cycle. In summary, the evaluations performed in this report indicate that Limerick Unit I can be operated safely considering the shroud inspection results and inspection coverage'through the next operating cycle since the resulting safety factor meets the required safety factors per BWRVIP-76 [1]. Details of the evaluation are summarized below in this letter.

INTRODUCTION/APPROACH During 4the March 2006 outage at Limerick Unit ;, UT inspections were performed on the core shroud horizontal welds Hi ,H2,IH3,'H4;1H5, H6, H7, VI 5, VI6,'V 17 and v18. During these inspections, a sufficient amount of weld length was inspected, which resulted in the detection of several flaws. Both an OD trackeranid TEIDE tool were used for the inspection for some of the welds in order to improve inspection coverage. Note that in cases where the OD tracker and TEIDE tool were used, the results

'were combined to develop the most conservative set of data for evaluation of the welds for structural integrity. No cracking was seen at welds V15 and V16.

,INSPECTION

SUMMARY

Reference 2 contains the inspection data used in this evaluation. The data sheets in Reference 2 present the indications observed if any, uninspected zones, and ci-ack depth information. The Reference 2 data was considered preliminary. Reference 3 contains the final inspection data. Comparison ofthe Reference 3 data with the Reference 2 data shows in most cases the data is identical. Inha few locations there were minor changes that would result in insignificant changes in the safety factor.

ANALYSIS SI's analysis was performed consistent with BWRVIP guidelines as provided in BWRVIP-76 and BWRVIP-14A. This section provides a summary of the evaluation for the various welds. Welds H3, H4,.V1 7 and V1 8 are subjected to high enough fluence such that LEFM or EPFM must be considered per BWRVIP-76. The evaluation of these three welds, per BWRVIP-76 must include consideration for both limit load and EPFM or LEFM. The analysis to demonstrate structural integrity of the H3, H4, V1 7 and VI 8 welds include consideration of both LEFM and Limit Load. In addition, crack growth over the next operating cycle is considered in the evaluations.

Applied Stresses The applied stresses at the horizontal welds were obtained from Reference 4. The primary membrane and primary bending stresses are shown for the normal/upset and emergency/faulted conditions. Note that these stresses are conservative since the loads have been revised in a later report. For purposes of

• thisevaluation, these conservative values will be used., In performing the structural integrity analysis of the weld, both normal/upset and emergency/faulted conditions must be considered.

Crack Growth Crack growth in the depth and length direction was accounted for by adding 2 years of growth to the measured flaws found during the 2006 inspection. Limerick Unit I has implemented a Hydrogen Water Chemistry system and plans to continue injection of hydrogen in the future.; Even though BWRVIP-14A, including the NRC SER, allows the use of a reduced K-independent crack growth rate of .1xl0.5 in/hr, a crack growth rate of 2.2xl 0"5 in/hr was conservatively~used for the through-wall direction. This results in total growth of 0.386 inches in the through-wall direction over the next two years. A constant crack growth rate of 5x10`5 in/hr was used in the length direction consistent with BWRVIP-76. The crack length increase at each end ofthe flaws is 5x 10. in/hr*8760*2=0.876 inches. This amount was added to the ends of all flaws.

Sizingi Uncertainty UT sizing uncertainties were considered in the evaluation of the flaws. Both length and depth sizing was considered. Sizing uncertainties were obtained from BWRVIP-03 [5] for the specific shroud demonstration qualification used.

' Ms. Michelle Karasek -March 23, 2006 SIR-06-121, Rev. 0/MLH-06-042 Page 3 of 7 Distributed Ligament Determination The determination of the flaw pattern is key to determining the remaining ligament for evaluation using the Distributed Ligament Length (DLL) program [6]. The general procedure is summarized below:

1. Postulate through-wall flaws at all uninspected regions.

2. Include penalty for one-sided inspection if applicable (alternatively assume fully cracked)

3. Add uncertainties (length and depth) to the flaws (both postulated and detected flaws).

4. Add crack growth (length and depth) to all flaws.'

5. Combine flaws if ligament between any two flaws is less than 2 times the thickness of the shroud thickness at the specific weld location.

The general procedure discussed above was applied all of the welds of interest. The specific weld evaluations; are provided below.

Welds H 1and H2 For these two welds, inspection on the ring side was limited. Although the inspection was limited, it did confirm that the ring's were not significantly cracked. For purposes of this evaluation, the Exelon position regarding one-sided inspections (reduce uncracked inspected ligaments by 50%)-was imposed.

- In addition, uninspected'regions on the shell side of the Weld were assumed cracked through-wall.

Fluence is not an issue at these two welds so only limit load analysis was performed.

Weld H4 Weld H4 was inspected on both sides of the weld. The H4 weld is of special significance because it currently has received a total fluence that is greater than 3 x 1020 n/cm 2 (E> I MeV) at some of the azimuthal and radial locations [7].' Per the requirements of BWRVIP-76, limit load analyses can be applied for core shroud welds for fluences below 3 x 1020 n/cm 2 (E> 1 MeV) due to the excellent toughness of these austenitic stainless steel shroud materials. Additionally, crack growth rates for un-irradiated austenitic stainless steels can be used up to fluences of 5 x 1020 n/cm 2 (E> 1 MeV), using the methodology contained within BWRVIP-76. At fluences greater than 3x 1020 n/cm2 (E> MeV) but less than I x 1021 n/cm 2 (E> 1 MeV), limit load in addition to elastic-plastic fracture mechanics or linear elastic fracture mechanics (LEFM) methodologies can be used for determining the allowable flaw size at the H4 weld. Above a fluence of I x 102! n/cm2 (E> I MeV), limit load and LEFM are used to determine the allowable flaw size at the weld.

For purposes of this calculation, LEFM and limit load was used to demonstrate the structural integrity of the H4 weld. -Note that since LEFM will be performed, it is not necessary to remove any material that is

':subjected to fluence greater 3x0 2 0n/cm 2 .1The limit load analysis that eliminates the material subjected to high fluence was an option'in lieU of performing an LEFM calculation as discussed in Reference 1.

Ms. Michelle Karasek March 23, 2006 SIR-06-121, Rev. O/MLH-06-042 Page 4 of 7 Limit Load Calculations

'Two cases were evaluated for limit load., These were:,,, .

1) Cracks were grown from the OD (one cycle worth of crack growth). If the. flaw entered into a region of fluence greater than 3x1 020,n/cm , the remainder of the material (between the flaw tip and the ID surface) was eliminated. This case is considered very conservative.

2) Cracks were grown from the OD (one cycle worth of crack growth) and all material was used in the limit load calculation (except that area within uninspected zones

• that were assumed cracked through 11.-w The DLL program [6] was used to determine the safety factors after one two-year cycle. As mentioned above, two cases were evaluated for the limit load calculation. Even with the conservative assumptions made, the safety factors are at or above the required safetyfactors of 2.77 for normal and upset conditions and 1.39 for emergency and faulted conditions.

Linear Elastic Fracture Mechanics An LEFM calculation was performed for the H4 weld assuming a 3600 flaw with depth equal to the maximum predicted flaw depth at the end of the next operating cycle. The stress intensity factor was calculated for the crack tip using the stress intensity factor distribution in BWRVIP-14A (including fit-up stress consideration) and adding the stress intensity factor for the stress values at Weld H4 for Pm and Pb. Results of this calculation show that the total stress intensity factor was well below the maximum allowable fracture toughness (including safety factors) per BWRVIP-76 and BWRVIP-100.

Weld H3 Some small areas of H3 are subjected to fluence greater than 3x10 20°n/cm2 [7]. For weld H3, a limit load analysis was performed discounting any material that was subjected to fluence greater than 3x. 02I n/cm 2.

Welds H5, H6 and H7 Weld H5 and H6 are all associated with a ring weld and double sided coverage was achieved. Weld H7

-,received sufficient inspection on both sides of the' weld and no indications were observed. Limit load analysis was performed assuming the uninspected zones were cracked through-wall for H5, H6 and H7.

,WeldsVl7andVl8 Vertical welds V17 and V18 lie between horizontal welds H4 and H5..A small portion of the welds is exposed to'fluence greater than 3x1 020 n/cm 2 . Both V17 and VI8 contained two relatively short indications and these indications are within the higher fluence region. In addition, both welds contain a

Ms. Michelle Karasek March 23, 2006 SIR-06-121, Rev. 0/MLH-06-042 Page 5 of 7 short uninspected portion at each end of the weld. Thrle evaluations were performed for these vertical welds:

1) Perform limit load per BWRVIP-76 assuming the indications are through-wall and combined.

2) Perform LEFM assuming the two indications are through-wall and that the through-wall flaw runs the entire length encompassed by the two indications.

3) Perform LEFM for the uninspected vertical weld portion, assuming the horizontal weld is fully cracked. Note that in this case a flap does not develop. It is conservative to assume H4 fully cracked since over 50% of H4 was inspected and the uninspected H4 region near the vertical welds can be conservatively assumed to have a flaw equal to the maximum crack depth seen in H4. In addition, the uninspected length of the vertical weld was conservatively assumed to be fully cracked through-wall. Thus, this condition is analyzed as a single edge cracked plate subjected to the hoop stress in the shroud at the H4 and H5 location.

RESULTS The following tables show the results of the structural integrity safety factor calculations. Safety factors for weld H4, VI 7 and VI 8 are presented for both LEFM and limit load.
