1.0 INTRODUCTION

1.1 Purpose Purpose of this document is to provide Non-Proprietary revision of document 32-5044089-03.

The document 32-5044089-03 contains the analysis and qualification of the repair in the Control Rod Drive Mechanism (CRDM) nozzles in the Reactor Vessel Closure Head (RVCH) in Palisades plant operated by Nuclear Management Company.

The purpose of this calculation is to fulfill the requirements of Reference 13.1. The repair design is qualified to meet the criteria of 1989 ASME Code,Section III, NB-3000 (Reference 13.2).

The analysis of the nozzle extension, nozzle to nozzle extension connection and support plate is performed in the Reference 13.20.

The stresses within the IDTB weld and original J-groove weld are also calculated in order to provide input for the fracture mechanics analysis.

1.2 Scope The Palisades Unit 1 Reactor Vessel Closure Head (RVCH) contains, among others, forty five (45) CRDM nozzles (Reference 13.9). Each of the nozzles is aligned vertically. They are located at various radial distances from the vertical centerline of the RVCH hemisphere. Based on the distance from the center of the hemispherical head, the relative angle of the nozzle vertical centerline and the plane of the head curvature varies. This angle is referred to herein as the "hillside angle". Experience (with analyses for nozzles located at various hillside angles in the upper head) indicates that the larger the hillside angle, the more severe the stress level. Based on this experience, the model herein represents the largest hillside angle of any of the CRDM nozzle locations (the outermost nozzle, #3845). This model is considered to produce results that are conservatively high for all nozzle locations that have a smaller angle. Qualification of the CRDM nozzle necessitated creations of a 3-D finite element model and stress analysis of the repair design. Thus, the model geometry uses the repair design and stress analysis is performed under conditions of the various Palisades RVCH loads.

2.0 ASSUMPTIONS There are no major assumptions made for the analysis contained in this document. Minor assumptions are noted where applicable.

PALISADES CRDM NOZZLE IDTB WELD REPAIR ANALYSIS - NON-PROPRIETARY A

AR EVA PLANT Palisades DOCUMENT NUMBER 32-5054514-00 INON-PROPRIETARY 3.0 CALCULATION METHODOLOGY The general methodology of model development and stress analysis consists of:

1) Building the finite element model including the reactor vessel closure head (RVCH),

penetration, remaining part of the original CRDM nozzle, replacement nozzle, original J-groove weld & buttering, repair internal diameter temper bead (IDTB) weld, materials, and boundary conditions. There are two finite element models consisting of thermal and structural elements respectively to enable the thermal and structural analyses. The "meshes" of the two models are same.

2) Applying the design conditions of pressure and temperature to the structural finite element model and obtaining the deformation and stresses in the model. The deformation field is used to verify the correct behavior of the model and correct modeling of boundary and load conditions. Attenuation of stress effects at regions distant from the nozzle is also verified.

3) Applying the thermal loads resulting from the plant operating transients (in the form of transient temperatures versus time and corresponding heat transfer coefficients). Evaluating the results of the thermal analysis by examining the magnitude of temperature differences between key locations of the model. The time points of the maximum temperature gradient are those at which the maximum thermal stresses develop.

4) Applying the corresponding pressure and thermal loads (nodal temperature) at each time point identified in step 3 and other time points of interest on the structural finite element model and obtaining the stress results.

5) Performing the ASME Code stress evaluation based on the finite element analysis results, which includes the assurance that failure does not occur due to the application of the design loads as well as the repetitive service loads.

6) Document stresses for the original J-groove weld for the fracture mechanics analysis.

AR EVA PLANT Palisades DOCUMENT NUMBER 32-5054514-00 INON-PROPRIETARY 4.0 FINITE ELEMENT MODEL The model simulates, in three-dimensional space, a 180-degree section of the CRDM nozzle and adjacent RVCH after the repair. The vertical plane containing the vertical central axis of the RVCH and vertical central axis of the CRDM nozzle forms the plane of symmetry for the modeled portion of the nozzle. The thermal and structural boundary conditions are reflective on this plane.

The RVCH is modeled for a sufficient distance away from the CRDM penetration (both in the uphill/downhill and circumferential directions) to assure that the stress effects have effectively attenuated. The adequacy of these distances is verified by review of solution runs for operational transients. In addition, due to the spacing of the CRDM Nozzles and the attenuation of the stress effects from the relatively small welds, no appreciable overlap of stress fields occurs between adjacent nozzles. Therefore, only a single CRDM nozzle is modeled.

The nozzle is modeled sufficiently beyond the head to include effect on the IDTB weld connection. The threaded connection is not modeled since this location is not the subject of interest in this analysis.

The finite element analyses in this document are performed using ANSYS 7.1 (Reference 13.3).

The model is shown in Figure 4-1 to Figure 4-4. The element type chosen is the SOLID92 (3D 10-Node Tetrahedral Structural Solid) for the structural analysis. This element is converted to element type SOLID87 (3D 10-Node Tetrahedral Thermal Solid) for the thermal analysis. The model is comprised of approximately 96000 nodes and 60000 elements.

PALISADES CRDM NOZZLE IDTB WELD REPAIR ANALYSIS - NON-PROPRIETARY A PLANT DOCUMENTr NUMBER AR EVA Palisades 32-5054514-01 1 NON-PROPRIETARY 4.1 Geometry The geometry of the model is based on Reference 13.4(4), 13.5, 13.9 through 13.12 for the outermost nozzle configuration (#38-45). Note that some of the small details in the geometry are not modeled since they have insignificant impact on the results and difference in the stresses is negligible(5). Some of the key dimensions used are:

RVCH inside radius to base metal = xxx in. (Reference 13.11)

RVCH base metal thickness = xxx in. (Reference 13.5)

RVCH Head cladding thickness = xxx in. (Reference 13.11)

Remaining Original Nozzle OD = xxx in.(l) (Reference 13.9)

Remaining Original Nozzle ID = xxx in. (2) (Reference 13.5)

Replacement Nozzle OD = xxx in. (l) (Reference 13.5)

Replacement Nozzle ID (at repair weld) = xxx in. (Reference 13.5)

Replacement Nozzle ID (away from repair weld) = xxx in. (3) (Reference 13.4)

Notes: (2)The OD of the nozzle is assumed equal to penetration diameter.

(2)The maximum nozzle inside diameter near the IDTB weld is conservatively used for other locations of Remaining Original Nozzle.

(3) The maximum Replacement Nozzle inside diameter is conservatively used for the whole section away from the repair weld.

(4) The length of the upper thick part of the Replacement Nozzle and the length of the transition from the thick to the thin part of the nozzle are slightly different from the Reference 13.4. Since this change is away from the investigated location, the impact on the results will be negligible and therefore these differences are acceptable.

Axial [kips] I Shear [kips] Mb [in-kips]

Note: these values represent load per "g'.

To obtain applicable loads, the unit loads are multiplied by the acceleration for CRDM specified in Reference 13.8:

Design (OBE) Safe Shutdown (SSE)

Horizontal l Vertical Note: to be consistent with the original calculation (Reference 13.15), also axial unit load is multiplied by the horizontal acceleration.

Thus, the external applicable loads are:

In addition Reference 13.8 specifies the CRDM SCRAM load of xxx kips each rod. Since this is a dynamic load, it will be conservatively multiplied by a factor of x. (FaC scRAM = xxx x x = xxx kips). This load is axially compressive due to the weight of the control rod and its extension shaft (and buffer piston) slamming into the hard stop at the bottom of the dry scram gravity fall stroke.

However, conservatively load will be considered as either compression or tension to maximize total stresses.

These loads are evaluated using hand calculation. The stresses due to these loads are added to the ANSYS results where appropriate for the ASME evaluation.

Total axial stress is s -=: a. F+r CAM = xxx ksi Where the stresses are taken from Table 5-5 for normal / upset condition.

Note that the remaining original nozzle is roll expanded during the repair. This roll expansion is considered to be hard enough to transfer bending loads to the RVCH and the IDTB weld will not be subjected to these loads. Therefore the axial bending stresses are not included in the total axial stresses. Also the axial membrane stress due to internal pressure is not used since this is already included in the ANSYS transient runs.

Since this is the only significant stress caused by external load (OBE and SCRAM), this axial stress also represents total stress intensity value.

Other related criteria include the design limits for minimum required pressure thickness (NB-3324) and reinforcement area (NB-3330). The requirements for minimum required pressure thickness and the reinforcement area are effectively addressed by meeting NB-3221.1, NB-3221.2 and NB-3221.3 as shown below.

NB-3221.1 - General Primary Membrane Stress Intensity (Pm1.OSm)

The applicable value occurs remote from discontinuities and includes no local effect. Path

'Headl ' (called as "Pathl" in output file) depicts an appropriate location for the RVCH base material. From "PALdes pres Path.out", the membrane stress intensity of path 'Headl ' is 13.32 ksi. For the RVCH base material, 1.0*Sm = 26.7 ksi (Table 9-1). Therefore, the requirement is met.

NB-3221.2 - Local Primary Membrane Stress Intensity (PL*51.5Sm)

The applicable value occurs across any solid section, considering discontinuities but not stress concentrations. Path 'Head2' (called as "Path2" in output file), which is taken one penetration radius away from the discontinuity into the head, depicts an appropriate location for the RVCH base material. From "PAL desjpres Path.out", the local membrane stress intensity of path

'Head2' is 15.05 ksi. For the RVCH base material, allowable stress = 40.05 ksi (Table 9-1).

Therefore, the requirement is met.

NB-3221.3 - Local Membrane + Primary Bending Stress Intensity (PL+ Pb,1.5SS)

The applicable value is taken from path 'Head2' (called as "Path2" in output file). The maximum membrane + bending stress intensity of path 'Head2' is 16.44 ksi. For the RVCH base material, allowable stress = 40.05 ksi (Table 9-1). Therefore, the requirement is met. Note, this is very conservative since Table NB-3217-1 of the ASME Code classifies this type of wall bending stress as a secondary stress 9.1.1.2 Primary Stress Intensitiesfor Level B Conditions Reference 13.8 indicates that there are three Upset condition transients - Loss of Load, Loss of Flow and Safety valves relieving. Per Reference 13.8, the maximum internal pressure is 2750 psia (for steady-state), the temperature varies from -535°F to 643°F. Since the pressure is higher than the Design Condition pressure, the pressure stresses induced by the Upset condition need to be evaluated and considered in this paragraph.

To quantify the Primary Stresses due to Upset Condition, the stresses of the Design Condition are multiplied by the ratio of the respective pressure values (xxx/xxx=xxx).

The following discussion describes the fatigue analysis process employed herein for the repair design.

Overall stress levels are reviewed and assessed to determine which model locations require detailed stress/fatigue analysis. The objective is to. assure that:

1. The most severely stressed locations are evaluated.

• 2.The specified region is quantitatively qualified.

9.2.1 Path Stress Evaluation The structural analysis of the transients indicates that the locations of high stresses are at the repair weld and the adjacent RVCH. The ANSYS Post Processor is used to tabulate the linearized stresses along paths through these locations and classify them in accordance with the ASME Code Criteria (i.e., membrane, membrane + bending, total etc). These paths are defined at the repair weld (material xxx) and the head area (material xxx) to allow stress evaluation in these materials separately. Review of the stress results and experience with analyses of similar configurations indicates that these sections include the location of the maximum stress/usage.

Note that paths in the nozzles are not required for the fatigue analysis, since these locations show smaller stresses, a FSRF of 2.0 can be used and the high alloy fatigue curve can be used for analysis.

The paths are shown in Figure 9-4 to Figure 9-5 and are described in Table 9-6. For post processor calculation, the definition of these paths is contained in the computer file "PAL path fat.mac". The linearized stress components for these paths are contained in the following computer output files:

Palisades 32-5054514-00 NON-PROPRIETARY 9.2.3 Fatigue Usage Factor Calculation For consideration of the fatigue usage, the Peak Stress Intensity Ranges are calculated. These values must include the 'total' localized stresses.

The geometry of the original and the repaired design results in a crevice-like configuration between the nozzle OD and the head penetration bore diameter. Therefore, the linearized

'membrane + bending' stress intensity range ("PAL Range(M+B).txt") at the crevice-like location is multiplied by a Fatigue Strength Reduction Factor (FSRF) of 4.0 (NB-3352.4(d),

Reference 13.2) to represent the Peak Stress Intensity Range.

The model used in the analysis may not depict all of the potential peak stresses for the fatigue analysis at the other locations. Therefore to bound the potential effect of this consideration, the other locations used in fatigue analysis are conservatively multiplied by a FSRF of 2.0.

The resulting values are confirmed to be greater than the 'total' stress intensities calculated directly from the model.

The following pages contain the calculation of the cumulative fatigue usage factor for the limiting point. The usage factor is calculated based on the design cycles shown in Reference 13.8 and Reference 13.1.

Per Reference 13.14, the maximum existing usage factor for the original nozzle is xxx for xxx years. Reference 13.14 also shows the existing usage factor of xxx for the Head Flange. Since this location is evaluated as the critical location of the Head, it is considered, that this is the maximum existing usage factor for the RVCH material. Therefore, this calculation considers the existing usage factor in repair design additional life calculation. Conservatively the xxx usage factor for xx years is added to the usage calculated from this analysis without adjusting for the years in service.

Upon reviewing the stress range results (from "PALRange(M+B).txt") and after taking into account the FSRF=4 for crevice-like location and FSRF=2 for the other locations, it is determined that the SI Ranges at path "Path5" outside node #14770 produce the highest usage factor for upper part of the IDTB weld connection (connected to the remaining original nozzle) and SI Range at path "Path9" outside node #11181 produce the highest usage factor for the lower part of the IDTB weld connection (connected to the replacement nozzle). Two locations are investigated because remaining original nozzle and replacement nozzle are exposed to the different external loads which are included in the fatigue calculation. Therefore, the fatigue qualification for these two locations is shown in this section. Conservatively, the low alloy fatigue curve is used for both locations, since these triple points also contain RVCH material.

The following calculation is provided to show the usage factor for xxx years of operation.

A.PALISADES CRDM NOZZLE IDTB WELD REPAIR ANALYSIS - NON-PROPRIETARY PLANT DOCUMENT NUMBER AR EVA Palisades 32-5054514-01 NON-PROPRIETARY 10.0 CONSIDERATION OF CORROSION OF RVCH BASE MATERIAL The design configuration of the nozzle repair results in a small area of the'RVCH base material (Low Alloy Steel xxx) being exposed to continuous contact with Reactor Coolant water. The chemistry of the Reactor Coolant combined with the properties of the RVCH wall material result in corrosion of the wetted surface.

The corrosion rate is determined to be xxx inch per year (Reference 13.7). At this rate, the total surface corrosion after xxx years of plant life (see Section 3.11 of Reference 13.1) is only 0.086 inch. This small amount of corrosion volume loss will not have a significant impact on the analysis.

Note that the loss of metal is expected to be much smaller in the annulus between the nozzle OD the bore due to the lack of flow. However, for conservatism, the loss of metal is assumed to be through the thickness of the low alloy steel material. The 0.086" increase in radius has a negligible effect on the stress levels and stress distributions in the wall. In addition, based on the diameter and thickness of the nozzle as well as the corrosion rate, the corrosion will not have any appreciable effect on the nozzle stresses and will not cause any denting. Thus, the larger bore diameter does not impact the stress / fatigue usage for the assembly and is acceptable.

In conclusion, the corrosion of the exposed low alloy steel material has negligible impact on the response of the RVCH nozzle repair and is therefore acceptable for 27 years from the time the modification is installed.

This calculation fulfills the requirements of Reference 13.1 Prepared by: P. KRAL Date: 12/2004 Page 64 of 106 Reviewed by: J. F. SHEPARD Date: 12/2004
