0 F0306-O1RO V Structural Integrity Associates, Inc.1.0 OBJECTIVE The objective of this calculation package is to determine if the ASME Code,Section III design requirements are satisfied for a weld overlay repair of the reactor coolant pump (RCP) discharge nozzle safe end welds at Davis-Besse Nuclear Power Station, Unit 1. Design drawings of the weld overlay repairs (optimized and full structural) are provided in References 1 and 2. This evaluation bounds both the optimized and full structural weld overlay designs.Several finite element stress and thermal analyses have been performed

[4] to support the ASME Code evaluations.

These analyses, together with the design requirements of the ASME Code, are used to determine the adequacy of the repair.2.0 DESIGN CRITERIA The weld overlay repair is designed to the requirements of the ASME Code,Section III for Class 1 components.

Thus, the rules of Article NB-3000 of Section III of the ASME Code, 2001 Edition with Addenda through 2003 [5] are used.The weld overlay repair region is located at the reactor coolant pump (RCP) discharge nozzle safe end, which will be treated as integral with the reactor coolant pump. The section of the ASME Code that is applicable to the pump design is Subarticle NB-3400. Subarticle NB-3400 provides general design requirements for pumps, but, it does not specifically provide stress intensity limits for the different Service Levels. Instead, different paragraphs within Subarticle NB-3400 refer to different areas of Subarticle NB-3200 for establishing the stress intensity limit requirements, noted as follows: " Paragraph NB-3414 refers to Subarticle NB-3 100 for general design considerations, and in turn, Subsubparagraph NB-3112.1 (a) refers to showing compliance of the stress intensity limits contained in Subsubarticle NB-3220 for the design pressure.

In addition, Subparagraph NB-3122.3 also refers to satisfying the stress intensity limits contained in Subsubarticle NB-3220 for the secondary and peak stresses." Subparagraph NB-3415(b) refers to the stress combination requirements of Subarticle NB-3200.o Subparagraph NB-3432(b) refers to meeting the stress intensity requirements of Paragraph NB-3222.Since the overall stress compliance requirements of the Subarticle NB-3400 refer to stress limits contained in Subarticle NB-3200, guidance from the rules of Subarticle NB-3200 of the ASME Code will be taken to satisfy acceptance criteria.Note that the safe end and cold leg pipe can be evaluated using the rules of Subarticle NB-3600, but is conservatively evaluated using the rules NB-3200 of the ASME Code.File No.: 0800368.325 Page 3 of 19 Revision:

& Structural Integrity Associates, Inc.3.0 LOADS This evaluation only considers Service Level A and Service Level B operating conditions in regards to meeting ASME Code,Section III Service Level A/B allowables and fatigue. As such, thermal stresses resulting from Service Level C and Service Level D thermal transients are not considered

[5, NB-3224.4 and Appendix F- 1310].Primary stresses (such as mechanical loads due to deadweight, and seismic effects) resulting from Service Levels A, B, C and D operating conditions were previously evaluated in References 8 and 11, and are discussed in Section 4.0.Pressure Per Table 5 of Reference 7, the operating pressure loads range from 15 psia (0 psig) to 2,620 psia (2,605 psig) throughout the various thermal transients, whose temperatures range from 70'F to 590'F. The Hydrotest pressure ranges from 15 psia (0 psig) to 3,125 psia (3,110 psig) and the corresponding temperatures are 100'F through 400'F. The pressures for various transients are summarized in Table 2.The gauge pressure is used in all calculations.

Thermal Transients Based on Table 5 of Reference 7, five bounding thermal transients (Heatup, Cooldown, Reactor Trip 8A, Reactor Trip 8C, and Change of Flow) and one test condition (Hydrotest) are considered.

These thermal transients were evaluated in Reference

4. Details of the various transients are shown in Table 2.The number of cycles shown in Table 2 are for the original 40-year design operating period [7] and are multiplied by 1.5 to generate cycles as if for a 60-year operating period. The complete set of cycles (for all 60 years) is evaluated for the repair configuration.

Details of the thermal stress analyses are provided in Reference 4.Mechanical Piping Loads The RCP discharge nozzle is subjected to mechanical piping loads due to thermal expansion, OBE, and deadweight.

These are defined in Table 3 of Reference

7. See Table 3 in this calculation for details.Note that deadweight loads are constant loads, which occur for all load conditions.

Therefore,.

deadweight loads do not contribute to the stress ranges for Service Levels A and B load combinations and fatigue evaluations (per NB-3222.2 and NB-3222.4) and are excluded for those evaluations.

4.0 LOAD COMBINATIONS The load combinations used in the repair design are: File No.: 0800368.325 Page 4 of 19 Revision:

0 F0306-O1RO V Structural Integrity Associates, Inc.1. Level A Load Combination

2. Level B Load Combination
3. Level C Load Combination
4. Level D Load Combination
5. Test Load Combination Two weld overlay sizing calculations were performed, one for an "optimized" weld overlay and one for a"full structural" weld overlay. These weld overlay sizing evaluations

[8 and 11 ] considered general primary membrane, Pm, and primary membrane-plus-bending, Pm+Pb, stress intensities resulting from Service Levels A and B operating conditions and Service Levels C and D conditions.

While local membrane, PL, stress intensities were not specifically evaluated, any local stress effects due to the weld overlay repair are expected to be minimal.The sizing calculations do not specifically evaluate loads resulting from the Test Load Combination (Hydrotest).

However, the Test Load Combination considers only primary stresses, which only result from pressure and mechanical loads. The added thickness of the weld overlay will only serve to reduce the general primary membrane and local membrane stress intensities, Pm and PL, respectively, and are not expected to be adversely affected when compared to the original configuration.

Therefore, the only load combinations which are considered herein are for Service Levels A and B. The specific load combinations are shown in Table 4. The allowable stress intensities for these load combinations are shown in Table 5 [5]. Also, as indicated in Table 5, for Service Levels A and B, peak stresses and cyclic operation criterion must also be met.Thus, this calculation, together with References 8 and 11, contains the ASME Code qualification for the weld overlay repair. This calculation bounds both the "optimized" and "full structural" weld overlay designs shown in References 1 and 2. The minimum overlay corresponds to the minimum "optimized" dimensions in Reference 1, and the maximum overlay corresponds to the maximum "full structural" overlay dimensions in Reference 2.It should be noted that in using the ASME Code,Section III, Class 1 rules in NB-3200, Service Levels A and B are combined together using bounding load combinations.

5.0 ASME CODE STRESS LIMITS EVALUATION Stress intensity ranges are calculated for the various load combinations shown in Table 4 and compared to the allowable limits shown in Table 5. Linearized through-wall stresses are extracted through six paths (Paths 1 through 6, see Figure 1) throughout the transient time histories and from the pressure and mechanical load analyses [4]. These calculated stress intensities are evaluated in accordance with ASME Code,Section III, Subarticle NB-3200 [5] for Paths 1 through 6.File No.: 0800368.325 Page 5 of 19 Revision:

0 F0306-O1RO Structural Integrity Associates, Inc.5.1 Service Level A/B Load Combination Examination of the membrane-plus-bending stresses from Reference 4 does not provide an obvious pairing of stresses resulting from the various thermal transients for determination of the worst operating ranges. Thus, the VESLFAT program [9] developed by Structural Integrity is used to calculate primary-plus-secondary (P+Q) and total (P+Q+F) stress intensity ranges. The same program is used to perform the fatigue usage analysis described in Section 6.0.The primary-plus-secondary (P+Q) and total (P+Q+F) component stress values are combined prior to use in the VESLFAT program. The thermal component stresses resulting at each time increment from the various thermal transients are added to the component stresses resulting from corresponding pressure, and to the component stresses resulting from corresponding mechanical loads. The combination of the various component results are manipulated to produce the combined transient stress conditions, including:

o The primary-plus-secondary (P+Q) and total (P+Q+F) stress components due to pressure are scaled from the 1,000 psi unit pressure evaluation performed in Reference

4. The actual pressure at specific time points for a given transient is defined in Reference 7 and shown in Table 2 of this calculation.

The pressure between any two specified time points is assumed to vary linearly throughout each of the thermal transients.

  • The primary-plus-secondary (P+Q) and total (P+Q+F) stress components due to axial and moment loads are calculated using the component stress results for moment (1,000 in-lb) and axial (1,000 lb) loads developed in Reference
4. Both in-plane and out-of-plane moment load analyses were evaluated in Reference 4, and the bounding stress results are used for Paths 1 through 6.The OBE piping loads are defined in Sections 3.0 and 5.0 of Reference 7 as having a total of 650 events (or cycles) over 40 years of operation.

The number of OBE events are multiplied by 1.5 to account for 60 years of operation.

Therefore, 975 (i.e., 650 x 1.5) cycles of OBE loading are applied to the thermal range loads with no self-cycling.

The OBE loads are added to the piping loads and to one of the thermal transient pair events that produce the highest stress intensity range, as determined on a per-path basis. For all paths, the full range OBE loads are used.All moments and axial forces related to piping mechanical loads are evaluated in the same manner for each event. The component moments and forces are added together where appropriate and the resulting moments and axial forces are then combined by SRSS to create a single bounding moment and axial force load.> Because it is not obvious which direction of applied moment and axial force loading produces the worst stress range, the evaluation considers both positive (Base case)File No.: 0800368.325 Page 6 of 19 Revision:

0 F0306-01RO W Structural Integrity Associates, Inc.and negative (Reverse case) loading directions for the thermal expansion and OBE loads, in order to determine the worst range.Cyclic information, as well as material property data, are also needed to complete the VESLFAT input, though they do not play a direct role in the determination of membrane-plus-bending stress intensity ranges. This data is needed to support the fatigue evaluations, and is discussed in detail in Section 6.0.Table 6 presents the evaluation of the primary-plus-secondary stress intensity ranges for Service Levels A/B operating conditions.

The stress ranges extracted from VESLFAT files, with the extension

  • .FAT, are the stress intensity ranges that produce the greatest ratio of stress intensity range versus allowable stress.Examination of the maximum primary-plus-secondary stress intensity range load pairs and fatigue causing load pairs (in the *.FAT files), for all of the 'Base' and 'Reverse' case evaluations, identified the controlling thermal transients to which OBE is applied. OBE is applied to the events as shown in Table 1. The correlation between the transients and event number is provided in Table 7. The 'Primary-Plus-Secondary' columns list the event that OBE is applied to create the largest primary-plus-secondary stress intensity ranges. The 'Fatigue' columns list the event where OBE is applied to create the largest alternating stress intensity range corresponding to the highest fatigue usage. Therefore, the results shown in Table 6 and Table 9 include the OBE loads for those thermal transient load pairs.File No.: 0800368.325 Revision:

The evaluations are performed in accordance with ASME Code,Section III, Subsubparagraph NB-3222.4(e)

[5], using the Structural Integrity developed VESLFAT program [9].6.1 VESLFAT Program The VESLFAT program requires three input files. The first is the *.CYC file, which includes the number of cycles for each load combination.

The data used in the *.CYC file is discussed in detail in Section 6.1.1. The second file is the *.FDT file, which includes the fatigue curve data, appropriate temperature dependent material properties, and simplified elastic-plastic limits and factors. These values are discussed in Section 6.1.2. The final input file is the *.STR file, which contains the component membrane-plus-bending and membrane-plus-bending-plus-peak (i.e., total) stresses for the various load conditions to be evaluated.

Additional details are provided in Section 6.1.3. As several load conditions occur within each load case, these load conditions will be identified by a number, which matches the load condition to the load case. This number is defined in the *.CYC file. Each of these three files must be identically named, with the exception of the file extension.

A number of intermediate files are generated, which can be used to check the final results. The *.ST 1 file is an echo output of the *.STR file but includes transformations to output the results in terms of psi.The *.ALL file reflects all of the stress range pairs that are calculated.

The *.PR file is a shortened version of the *.ALL file and lists only the significant (i.e., fatigue causing) pairs. The *.ORD file re-sequences the *.PR file such that the ordered pairs are arrayed in order of reducing alternating stress.The actual final output file is labeled *.FAT. It echoes the input data, shows the significant cycle pairings, the cycle elimination, individual cycle pair fatigue contributions, and the final overall fatigue usage. See Section 6.1.4 for fatigue results.6.1.1 Cyclic Data (*. CYC)Reference 7 assigned a total number of cycles for each bounding event, which are tabulated in Table 7.As the piping OBE loads are added to the thermal transient pair events that produce the highest stress intensity range, the higher of the two cycle numbers from the OBE event and the pairing thermal transient event is conservatively used.See Appendix B for an example of a *.CYC file.File No.: 0800368.325 Page 9 of 19 Revision:

0 F0306-O1RO Structural Integrity Associates, Inc.6.1.2 Fatigue Data Input File (*.FDT)The materials at the surfaces of the stress paths indicated in Figure 1 are tabulated in Table 8.The fatigue curve for the stainless steel components is per Reference 5,Section III Appendices.

The curve consists of two portions; the low cycle stress portion (106 cycles) that is covered by Figure 1-9.2.1, and a high cycle portion for which Curve C, Figure 1-9.2.2, is conservatively used.The fatigue curve for the A-516 Grade 70 material is also per Reference 5,Section III, Appendices.

Both curves presented in Figure 1.9.1 are used, with the conservatively lower alternating stress, Sa, used throughout.

The modulus of elasticity correction factor from the fatigue curves are based on Reference 6 temperature dependent modulus of elasticity values with a fatigue curve elastic modulus of 28.3e6 psi for the austenitic materials, and 30.0e6 psi for the A-516 Grade 70 material.See Appendix B for an example *.FDT file.6.1.3 Stress Data Input File (*. STR)Linearized through-wall membrane-plus-bending (P+Q) and membrane-plus-bending-plus-peak (P+Q+F) component stresses from the finite element stress analyses [4] are extracted for pressure, mechanical, and thermal transient loads. Stresses are scaled in cases (pressure and mechanical) where the applied load magnitude is not the same as that analyzed.The resulting component stresses are then added together to create the load combination for each thermal transient throughout the length of the event. Thus, thermal stresses are added to the scaled pressure stresses and to the scaled mechanical load stresses to create each membrane-plus-bending and membrane-plus-bending-plus-peak component stress entry.Paths 1 through 6 terminate at outside locations with geometric discontinuities.

For these locations, the magnitude of the P+Q+F stress is determined by applying a fatigue strength reduction factor to the P+Q stress obtained from the finite element analysis [4].For Paths 1 through 6 outside, the fatigue strength reduction factors were 2.635, 2.426, 3.010, 2.410, 2.264, and 2.275, respectively.

These values are based on Reference 10, pages 91 and 92, and the minimum and maximum weld overlay dimensions (taken from the finite element models in Reference 3), where: ,8= angle of contour= 9.7' for Path 1 outside (for maximum overlay)= 44.4' for Path 2 outside (for minimum overlay)= 14.90 for Path 3 outside (for maximum overlay)= 48.4' for Path 4 outside (for minimum overlay)= 45.00 for Path 5 outside (for minimum overlay)= 74.00 for Path 6 outside (for maximum overlay)File No.: 0800368.325 Page 10 of 19 Revision:

For those paths that do not occur at a geometric discontinuity, no fatigue strength reduction factor is used. Instead, the membrane-plus-bending-plus-peak (P+Q+F) component stresses from the finite element stress analyses [4] will be used directly.The *.STR file includes the temperature of the location as it varies throughout the events and the pressure.

The pressures vary as indicated in Table 2. The temperature at the location is based on the actual metal temperature of the material rather than the fluid temperature.

These metal temperatures are extracted from the prior stress evaluations in Reference 4 via the linearized stress results files which include the temperature data in the last field under "Total" stress.Because it is not obvious which direction of applied force and moment loading produces the worst stress ranges, the fatigue evaluation considers both positive (Base Case) and negative (Reverse Case)mechanical load directions, in order to capture the worst ranges and, therefore, the greatest fatigue usage.An example of the *.STR file is shown in Appendix B.File No.: 0800368.325 Page 11 of 19 Revision:

0 F0306-O1RO V Structural Integrity Associates, Inc.6.1.4 Fatigue Usage (*.FAT)The fatigue evaluation automatically selects the load pairs that create the greatest stress intensity range, performs a K, calculation, corrects for the modulus of elasticity, and performs the fatigue evaluation.

It repeats this process selecting the next highest stress range until the available cycles are used up or the remaining stress ranges fall below the endurance limit. An example *.FAT file is included in Appendix B. The intermediate solution files *.ST1, *.ALL, *.PR, and *.ORD are included with computer files.Table 9 tabulates the total fatigue usage for each location.

In addition, the table includes information on the load pairing which produces the greatest alternating stress for each location, including the membrane-plus-bending stress intensity range, the calculated K, elastic-plastic factor, and the alternating stress, Sa, for the specific load pair.

7.0 CONCLUSION

S An evaluation of the reactor coolant pump discharge nozzle safe end with weld overlay repair for Davis-Besse Nuclear Power Station, Unit 1 has been performed in accordance with the requirements of the ASME Boiler and Pressure Vessel Code,Section III, for Class 1 components

[5]. Stress intensities were conservatively determined for pressure, piping loads and bounding thermal transients provided in Reference 7, and compared to ASME Code allowable values for primary-plus-secondary stress effects.In all cases, the reported values of stress intensity are less than their corresponding allowable values.A detailed fatigue analysis was also performed.

For the given number of expected cycles over a 60-year period, tabulated in Table 7, the total usage at all locations evaluated is below the allowable value of 1 (see Table 9).In conclusion, the reactor coolant pump discharge nozzle safe end with weld overlay repair design provided in References 1 and 2 satisfy the requirements of the ASME Code, and are qualified for the balance of plant life.File No.: 0800368.325 Revision:

2. The cycles provided in Table 5 of Reference 7 are for 40 years of operation, and need to be multiplied by 1.5 for this analysis to account for 20 years of additional life.3. OBE is identified in Reference 7 as 650 events (or cycles) occurring over 40 years. These cycles will be conservatively applied to the bounding transient pairing, with no self-cycling.

Similarly, these cycles need to be multiplied by 1.5 for this analysis to account for 20 years of additional life.Table 8: Materials for Fatigue Evaluation Path") Surface Material 1 Inside & Outside SA-430 FP316 (3)2, 4, and 6 Inside SA-240 304L(2)2, 4, and 6 Outside SA-516 Grade 70(2)3 Inside & Outside SA-182 F316(2)5 Inside & Outside SA-376 TP316(2)Notes: 1.
