1.0 OBJECTIVE The objective of this calculation is to perform stress analyses due to applicable thermal transients and unit mechanical loads on the reactor coolant pump (RCP) discharge nozzle weld overlay repair at Davis-Besse Nuclear Power Station. The geometry, including the weld overlay, is generated in a separate finite element model development calculation [1].
Several stress paths are defined through the location of the weld overlay repair. The stresses extracted along these paths are stored in computer files and will be used in separate ASME Code,Section III qualification and fatigue crack growth evaluations.
2.0 ASSUMPTIONS o For the thermal transients and internal pressure analyses, plane strain conditions are assumed at the cold leg piping free ends to simulate the connected piping.
o For all thermal and mechanical load cases, plane strain conditions are assumed at the free end of the cold leg spray nozzle to simulate the connected piping.
" For all thermal and mechanical load cases, axial and rotational constraints are applied at the free end of the pump body. This provides a rigid pump body, while still allowing proper thermal expansion at the free end.
o The stress free reference temperature for the thermal strain calculation is assumed to be 70'F.
o The exterior surfaces of the cold leg piping, RCP discharge nozzle and pump body are assumed to be perfectly insulated [2].
o Bulk fluid temperatures and heat transfer coefficients are applied to all interior surfaces with the exception of the pressure tap nozzle which is assumed to be capped and therefore has no significant circulation.
o Due to model symmetry, a duplicate cold leg spray nozzle is created in the out-of-plane moment model, but as no boundary conditions nor stress paths are local to this area the effects are deemed negligible.
3.0 DESIGN INPUT 3.1 Finite Element Models Two three-dimensional finite element models were developed for operating stress analyses in a previous calculation package [1] using the ANSYS finite element software package [3]. One model was developed using minimum "optimized" weld overlay dimensions (to be used for mechanical loading analyses), and another was developed using maximum "full structural" weld overlay dimensions (to be used for thermal transient analyses). Using the minimum "optimized" weld overlay configuration for mechanical loading, and using the maximum "full structural" weld overlay configuration for thermal transient analyses, is expected to yield conservative stress results.

The models include the reactor coolant pump discharge nozzle, the nozzle-to-safe end weld, the safe end, the safe end-to-piping weld and weld butter, a postulated ID weld repair (2-D residual minimum optimized weld overlay dimension model only), a portion of attached cold leg piping (elbow) and pipe internal cladding, the stainless steel buffer layer, the cold leg spray nozzle, the pressure tap nozzle and associated weld, and the weld overlay repair, as shown in Figures 1 and 2. Additional details regarding the development of these models are provided in Reference 1.
The finite element models are constructed using the 8, 10, and 20-node elements, SOLID45, SOLID92, and SOLID95, respectively. These elements are converted to thermal solid elements (SOLID70, SOLID87, and SOLID90, respectively) for the thermal transient analyses to determine the resulting temperature distribution time histories. The structural solid elements are then used to calculate the stresses due to the thermal loads, as well as the mechanical loading stresses. Additional details regarding the development of these models are provided in Reference 1.
3.2 Material Properties The material properties are included in the Reference 1 model creation process, and are left unchanged for the analyses performed herein.
3.3 Thermal Transient Definitions A total of six thermal transients are evaluated based on Table 5 of Reference 2. The temperatures for these transients are shown in Table 1. The Hydrostatic Test is not evaluated as a transient but as two steady-state conditions.
4.0 METHODOLOGY The finite element models developed in Reference 1 are used to analyze the mechanidal loading and the thermal transients shown in Table 1 using the ANSYS finite element software [3]. The unit mechanical loading includes internal pressure, axial loading, and in-plane and out-of-plane moment loading. The resulting stresses are then scaled in later ASME Code,Section III and crack growth analyses using the actual load magnitudes.
For conservatism, the finite element model with the minimum "optimized" overlay dimensions was used to perform stress analyses of unit mechanical loadings (unit pressure, unit axial and unit in-plane and out-of-plane moments); the finite element model with the maximum "full structural" overlay dimensions was used to perform thermal transient analyses.
In support of future ASME Code,Section III stress and fatigue evaluations, several through-wall stress paths are defined through the RCP Discharge nozzle weld overlay repair region and linearized stresses are extracted along these paths. Several additional paths are defined to support future fatigue crack growth analyses, and mapped (hoop and axial) stresses are extracted along these paths. Stresses for mechanical loading analyses are extracted from the model with the minimum "optimized" weld overlay File No.: 0800368.323 Page 5 of 29 Revision: 0 F0306-011

dimensions; stresses for thermal analyses are extracted from the model with the maximum "full structural" weld overlay dimensions. The stress results are stored in computer files for usage in future calculations, which will address ASME Code,Section III and crack growth evaluations.
5.0 ANALYSIS Four separate mechanical loading analysis and five separate thermal transients stress analyses are performed as described in the following sections. The Hydrostatic Test is not evaluated as a transient but as two steady-state thermal conditions.
5.1 Thermal Transient Definitions 5.1.1 Thermal Analyses Appropriate bulk fluid temperatures and heat transfer coefficients are applied to the interior nodes of the cold leg pipe and RCP Discharge nozzle as specified in Reference 2 and shown in Table 1 herein. No heat transfer coefficients are applied to the outside surfaces of the cold leg pipe and RCP Discharge nozzle since the surfaces are assumed to be perfectly insulated. The heat transfer film coefficients that are applied to the interior nodes are depicted in Figure 7 and are applicable for all transients. An additional time of one hour is appended to the end of each transient to ensure that any lagging peak stresses are captured.
5.1.2 Thermal Stress Analyses Axial and rotational constraints are applied at the free end of the pump body and symmetry boundary conditions along the half model planes of symmetry. The axial free end of the cold leg piping (elbow) and the cold leg spray nozzle are coupled in their respective axial directions. The boundary conditions for the thermal stress analyses are shown in Figure 8. By coupling the nodes in the axial displacement direction at the cold leg, no resulting moment is generated. The coupled boundaries allow axial thermal expansion while simulating the un-modeled attached piping's resistance to overturning moments.
5.2 Mechanical Stress Analyses 5.2.1 Internal Pressure A unit internal pressure of 1,000 psi is applied to the interior surfaces of the model. An end-cap load is applied to the free end of the attached cold leg piping (the elbow), the spray nozzle and the pressure tap in the form of a tensile axial pressure, the values of which are calculated below. These end-cap loads are included to simulate axial line loads induced by pressure at bends and transmitted through the un-modeled piping systems. The ANSYS program assumes that a positive value for pressure results in a load applied into the surface of the structure. In order to generate "traction" or a load away from the surface of the structure, it is necessary to apply the pressure with a negative value. Therefore, the end-File No.: 0800368.323 Page 6 of 29 Revision: 0 F0306-0o

cap loads calculated below will be applied in ANSYS using the negative of the calculated values. The applied pressures are shown in Figure 3.
Axial and rotational constraints are applied at the free end of the pump body and symmetry boundary conditions along the half model planes of symmetry. The axial free end of the cold leg piping (elbow),
the pressure tap and cold leg spray nozzle are coupled in their respective axial direction. The boundary conditions for the unit pressure analysis are shown in Figure 3.

5.2.2 In-Plane Moment The 1800 finite element model is used to evaluate the in-plane moment loading. The finite element model can be seen in Figure 4 with the applied boundary conditions and load. Axial and rotational constraints are applied at the free ends of the pump body and symmetry boundary conditions along the half model planes of symmetry. The free end of the cold leg spray nozzle is coupled in its axial direction.
An in-plane unit moment of 1000 in-lb is applied about the positive local Cartesian (coordinate system
- 54) Z-axis (for a half model, a 500 in-lb moment is actually applied). The moment is applied to the free end of the attached cold leg piping (elbow) by making use of a pilot node to transfer the loading. The TARGE 170 target element type from the ANSYS element library is used to create the pilot node. The CONTA174 contact element type is used to create a contact surface at the free end of the elbow. The pilot node and surface are bonded together, so that the moment applied to the pilot node is transferred to the free end of the elbow.
5.2.3 Out-of-Plane Moment A modified, full 3600 finite element model is used to evaluate the out-of-plane moment loading. The finite element model can be seen in Figure 5 with the applied boundary conditions and load. Due to model symmetry a duplicate cold leg spray nozzle is created, but as no boundary conditions nor stress paths are local to this area the effects are deemed negligible. Axial and rotational constraints are applied at the free ends of the pump body. The free end of the original cold leg spray nozzle is coupled in its axial direction. The fictitious second spray nozzle (resulting from the reflection of the half-model) is not coupled as there is no piping present. An out-of-plane unit moment of 1000 in-lb is applied about a local negative Cartesian (coordinate system 54) X-axis. The moment is applied to the free end of the attached cold leg piping (elbow) by making use of a pilot node to transfer the loading. The TARGE 170 target element type from the ANSYS element library is used to create the pilot node. The CONTA 174 contact element type is used to create a contact surface at the free end of the elbow. The pilot node and surface are bonded together, so that the moment applied to the pilot node is transferred to the free end of the elbow.
5.2.4 Axial Force An axial force of 500 lbs is applied in the positive Global-X direction to the half model (thereby generating 1000 lbs of equivalent loading for the full structure) at the free end of the attached cold leg piping (elbow) to simulate axial loads acting on the RCP Discharge nozzle/weld overlay. An opposing moment is then applied about the postive Global-Z direction to counteract the induced moment associated with the application of the force at the free end of the attached cold leg piping elbow. The opposing moment is determined as follows.
Mcounter = Faxial
- Lpipe = 500 lbs
- 9.78 inches = 4888.5 in-lb where:
Mcounter =
Counter moment, in-lb Faxial
= Applied axial force, 500 lbs Lpipe
= Perpendicular distance from application of force to nozzle centerline, 9.78 inches [1]
File No.: 0800368.323 Page 8 of 29 Revision: 0 F0306-011
V Structural Integrity Associates, Inc.
The addition of the counter moment is necessary, as the resulting stresses need to be the result of a pure axial loading. Because of the elbow's proximity to the weld overlay, the only reasonable application point for the axial load is the free end of the elbow. The axial load produces an undesired moment addition which needs to be countered.
The axial force is applied as a distributed nodal force to the end-section of the attached cold leg piping.
The opposing moment is applied to the free end of the attached cold leg piping (elbow) by making use of a pilot node to transfer the loading. The TARGE 170 target element type from the ANSYS element library is used to create the pilot node. The CONTA174 contact element type is used to create a contact surface at the free end of the elbow. The pilot node and surface are bonded together, so that the moment applied to the pilot node is transferred to the free end of the elbow. Axial and rotational constraints are applied at the free end of the pump body and symmetry boundary conditions along the planes of symmetry. The free end of the cold leg spray nozzle is coupled in its axial direction. The boundary conditions and loads for the unit axial force analysis are shown in Figure 6.
6.0 RESULTS Stress paths are defined around the region of the weld overlay repair. Stresses are linearized along Paths 1 through 6 for all time steps in the analyses (unit loads and thermal transient loads) and the results are saved to an Excel Workbook format for later ASME Code,Section III evaluations. The linearized stress paths are shown in Figures 9 and 10. The axial and hoop stresses are mapped along Paths 7 through 15 to support crack growth calculations for all time steps in the analyses (unit loads and thermal transient loads) and output to *.OUT files. The crack growth paths are shown in Figure 11 and 12. All of the files are included with the project computer files (see Appendix A for file listings).
Representative total stress intensity contour plots are provided in Figures 13 through 16 for the mechanical loading analyses. The temperature and stress intensity contour plots for the Heatup transient at 17532 seconds, as an example, are shown in Figures 17 and 18 for the thermal and stress passes respectively.
7.0 CONCLUSION
S A unit internal pressure analysis, in-plane moment analysis, out-of-plane moment afialysis, axial load analysis, and six separate thermal transient stress analyses are performed, and both linearized and mapped stresses are extracted and saved for later fatigue crack growth evaluations and ASME Code,Section III stress and fatigue evaluations. The stress results are saved in individual files for future usage.
