SE NOV 6Nuclear LLC LR-N05-0446 U. S. Nuclear Regulatory Commission Document Control Desk Washington, DC 20555 ASME CODE RELIEF REQUEST SALEM GENERATING STATION - UNIT I AND UNIT 2 DOCKET NOS. 50-272 AND 50-311 FACILITY OPERATING LICENSE NOS. DPR-70 AND DPR-75 Pursuant to 10 CFR 50.55a(a)(3)i), PSEG Nuclear LLC (PSEG) requests relief from American Society of Mechanical Engineers (ASME) Section Vill, Division 1, UG-27.
This section does not permit the use of plastic analysis; however, ASME Section Vill, Division 2 does permit the use of plastic analysis provided minimum wall thickness requirements are satisfied and any seam welds are fully radiographed.
This relief request is being submitted in an effort to align the lower design pressure of the Component Cooling (CC) heat exchanger with that of the remainder of the Salem Service Water System. Analysis has been performed which demonstrates that there is adequate safety margin of the CC Heat Exchanger under the design pressure requirements. PSEG is requesting for deviation from the normal approach of performing calculations. The proposed alternative is to use plastic analysis of the CC heat exchanger using the methodology provided in ASME Code, Section Vil Division 2, 2004 Edition, Appendix 4, Paragraph 4-136.4.
If you have any questions please contact Mr. Justin Weame at 856-339-5081.
Sincerely, Thomas P. Jove Site Vice President Salem Generating Station Attachments (1) Relief Request SC-RR-W03.

Alternative Provides Acceptable Level of Quality and Safety Component Description Component Cooling (CC) shell-and-tube heat exchangers (1 CCE5, 2CCE5, 2CCE6)
Applicable ASME Code Edition and Addenda:
American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code), Section VilI - Division 1, 1968 Edition, with No Addenda (Reference 1),
Paragraph UG-27 provides the requirements for the minimum wall thickness.
Reason for Request
Background The current design pressure for the tube-side (head) of the heat exchangers is less than the Service Water (SW) System design pressure. The vessel design pressure is 150 psig versus a SW system design pressure of 200 psig. The SW system typically operates at a pressure under 150 psig. However, under certain system cold weather configurations, the operating pressure can increase above 150 psig. The maximum operating pressure would occur following a loss-of-offsite power (LOOP) event due to the combination of three pumps operating and decreased winter flow demand as the Containment Fan Cooler Units (CFCUs) and non-safety flow loads are automatically isolated. In this configuration, the system pressure is expected to be approximately 180 psig, with some components experiencing slightly higher pressures due to hydrostatic pressure.
In order to address this issue, an evaluation was performed of the SW side of the heat exchangers to demonstrate that the ASME Code margins are maintained at the worst-case operating conditions. The goal was to demonstrate acceptability of the SW side of the heat exchangers to 200 psig for compatibility with the system design pressure. This analysis is documented in S-C-SW-MEE-1882 (Enclosure 1). The evaluation concluded that the CC shell-and-tube heat exchangers are acceptable per the original Code to 154 psig. This pressure was limited by the minimum wall thickness requirements of the Code for the channel (i.e., the channel head minimum wall thickness criteria per Paragraph UG-27 are not met for higher pressures).
Specific Code Issues This relief request is to permit the use of an alternative analysis that will demonstrate that the CC heat exchangers meet the intent of the ASME Code for a pressure of 191 psig. This pressure (191 psig) is high enough to satisfy all of the system pressure requirements for the CC heat exchanger.

Alternative Provides Acceptable Level of Quality and Safety The standard ASME Code calculations identify three areas that do not meet the standard Code requirements at the higher SW pressure (191 psig). Specifically,
- 1. The existing channel head wall thickness is 0.625 inches versus a required wall thickness 0.756 inches.
- 2. The existing nozzle reinforcement area is 7.48 in2 versus a required reinforcement area of 14.17 in2.
- 3. The existing channel flange minimum thickness is 4.63 inches versus a required thickness of 5.05 inches, based on maintaining an allowable stress of 17.5 ksi.
Proposed Alternative and Basis for Use:
Proposed Alternative The proposed alternative is to allow the use of plastic analysis of the CC shell-and-tube heat exchanger channel using the methodology provided in ASME Code, Section Vill -
Division 2, 2004 Edition, Appendix 4, Paragraph 4-136.4.
Basis for Use The issues related to the channel heads were evaluated using a finite element analysis (FEA). The FEA (enclosure 2) evaluated the inlet/outlet head using a three-dimensional model, which included the head, the nozzle and the flange. This permitted a single model to address all three design code compliance issues, as detailed in the previous section. The FEA included both elastic analysis and plastic analysis.
A scoping elastic analysis, using the allowable stresses provided in Section Vil -
Division 1, concluded that the flanges and nozzle reinforcement are acceptable for a SW pressure of 191 psig. However, the additional support provided by the nozzles and the pass partition plate are not enough to limit the membrane stress in the channel head to less than the allowable stress. Hence, a plastic analysis was necessary to justify operation at higher pressures. Plastic analysis can support higher working pressures by accounting for such strengthening phenomenon as strain hardening, redundancies by load shedding to other locations and strengthening by changing the basic shape of the component (i.e., large deflections).
The original Code of Record (ASME Section VilI - Division 1) does not permit the use of plastic analysis. However, ASME Section Vill - Division 2 does permit the use of plastic analysis, provided the minimum wall thickness requirements are satisfied and any seam welds are fully radiographed. The CC shell-and-tube heat exchangers do not satisfy either of these conditions. The minimum wall thickness requirement is not met 2

Alternative Provides Acceptable Level of Quality and Safety and the seam welds were only spot radiographed. Accordingly, the FEA results could not be used to support a formal Code evaluation of the heat exchangers. Regardless, plastic analysis was used to determine whether overall Code margins to failure (i.e., 2/3 factor of safety to plastic collapse) would be maintained.
The plastic analysis showed that the 2/3 factor of safety on plastic collapse was maintained for channel head elements subjected to internal pressure of at least 191 psig (even though the minimum wall thickness requirements are not satisfied). This was accomplished by accounting for such strengthening phenomenon as strain hardening, redundancies by load shedding and changing the basic shape of the component (i.e., large deflections). The head shell material is a 90-10 Cu-Ni material which is very ductile at 30% elongation. The flange is also constructed of a ductile material (carbon steel). The analysis approach is an adaptation of the Section Vil -
Division 2 procedure.
A 15% reduction of the stress-strain curve was made to philosophically account for the joint efficiency associated with spot radiography. This is not in accordance with the Code, but was done to maintain the overall Code approach of penalizing allowable stresses based on the level of inspections performed.
Allowable stresses were based on Section Vil - Division 1 allowable stresses.
When plastic analysis is used, the Code also requires that fatigue and ratcheting be specifically considered, because of the potential for higher than typical strains. For fatigue, the number of pressure cycles experienced by the channel heads is very low and the fatigue is not considered significant. Ratcheting is not considered a concern because the plastic analysis included a 15% reduction factor on the yield strength to account for the joint efficiency. This reduction is analytical, but in reality, sections will not develop plastic hinges until the actual minimum yield strength is reached, which is at higher pressures. Therefore, ratcheting is not considered to occur.
Conclusion Through the use of plastic analysis, it is demonstrated that the flanges and nozzle reinforcement are acceptable at a pressure of 191 psig, and that the inherent Code 2/3 margin to plastic collapse of the channel head (inherent in the ASME Code) is met for at least 191 psig. Based on this result, it is concluded that the heat exchanger provides margin that is consistent with the intent of the Original Code.

Page No.: 4 1.0 PURPOSE This calculation is a Section Vm11, Division 1, 1968 Edition (Reference 1) evaluation of the Salem Unit I Component Cooling (CC) Heat Exchanger Nos. 11, 21, and 22. The allowable stress for the cover bolting is from the 2001 edition of the ASME Code. TMe heat exchangers are evaluated for an incrcase in the tube side design pressure from 150 psig to 191 psig. Only the heat exchanger components that are affected by the design pressure increase are evaluated. As such, this is a partial code evaluation of the tube-side of the Component Cooling Heat Exchangers and is an addenda to the original code evaluation.

The joint efficiency for the tube is
= 0.6. This assumes the tube is a single sided butt weld and that no inspection was performed, which is conservative.
- 2.
Joint efficiencies for the inlet nozzle and outlet nozzle are E
= 0.8. This conservatively assumes the weld is a single sided butt weld with spot radiography (spot radiography is specified on Reference 4).
- 3.
The manway gasket is a full face gasket design. For the gasket seating load calculation, the gasket is assumed to have an OD equal to the bolt circle diameter minus the bolt hole diameter. This gives a smaller than actual gasket surface area, which is considered to give a reasonable load for the gasket seating load calculation.
- 4.
The gasket area for the gasket seating load calculation is based on the gasket OD and ID; the area for the gasket seal to the pass partition plate is not included in the gasket area.
- 5.
No credit is taken for the thickness of the 90-10 CuNi integral clad on the carbon steel manway cover and tubesheet.
- 6.
The channel flange is evaluated as a loose type flange, i.e., no credit is taken for stiffening provided by the channel hub. This is a conservative approach that simplifies the analysis, since the flange ring and hub are different materials (carbon steel and 90-10 CuNi).
- 7.
The manway flange thickness is evaluated with the approach in Reference 1. Paragraph UA-6(b)(2). Thbis provides the required flange thickness for a spherically dished cover with a full face gasket. This evaluation approach is suggested in Reference 1, Paragraph UA-56, since the typical flange evaluation in Appendix A is not applicable to full face gaskets.
- 8.
The corrosion allowance of the 9010 CuNi materials is 0 inches based on Reference 13. A corrosion allowance of 0 inches was also used for the titanium tube.

Revision: 0 1.0 PURPOSE This calculation documents a finite element analysis of the Service Water side of the Component Cooling (CC) Heat Exchangers Nos. II, 21, and 22 at Salem. PSEG Nuclear is currently re-evaluating the Salem Service Water (SW) system heat exchangers for an increase in design pressure from 150 psig to 200 psig. This analysis is being performed as part of that effort. This elastic-plastic finite element analysis calculates the collapse pressure of the heat exchanger channel.
2.0
SUMMARY
OF RESULTS Using the methodology of Reference 7, Appendix 4, 4-136.5, the maximum allowable pressure for the SW sidebf CC Heat Exchangers Nos. I 1, 21, and 22 is 267 psig. This is not a certification that the Heat Exchangers meet all applicable ASME B&PV code requirements.
3.0 FlNnE ELEMENT MODEL A three-dimensional finite element model of the CC heat exchangers "A" channel has been prepared to calculate the collapse load of the heat exchanger head. Note that the "A" channel is larger than the "B" channel. Therefore the results of this analysis are bounding for both channels.
While this calculation uses a methodology described in the ASME B&PV, it does not certify that the CC heat exchanger is in compliance with all ASME B&PV requirements.
The finite element analysis was performed using the ANSYS general purpose finite element computer program Version 8.1 on a Sun Microsystems 280R server running the Solaris 8 operating system. The ANSYS installation verification is documented in QA-8 I-I 3.1 Model Geometry The model geometry is taken from References I through 3. Channel UA" is modeled along with approximately 2 feet of the heat exchanger shdl. Note that this section of shell is not being evaluated, but is included for boundary conditions only. In addition, the cover and nozzle flanges are conservatively not included in the model. Scoping evaluations indicated that these components do not significantly impact the behavior of the channel shell. No credit is taken for the structural strength of the tubesheet clad.
The model is a three-dimensional half model, with the axis of symmetry at the along the heat exchanger axial length at the nozzle centerline. Figure 3-1 shows the model geometry. The model is meshed with 3-D solid elements with 10 nodes (ANSYS Element SOLID45). Figure 3-2 shows the model mesh.

SA-105-11 Tubesheet Heat Exchanger Shell SA-5 15 Grade 70 Nozzle Repad To properly account for the redistribution of load and potential concentration of strain for loads that produce stresses beyond the elastic limit, elastic-plastic material properties were included in this analysis. The behavior of the channel shell is of particular interest. Therefore, a stress-strain curve was developed for SB-171 90-10 Cu-Ni. Bi-linear stress-strain curves were used for the -
carbon steel portions of the model (SA-150-11 and SA-515 Gr. 70). Key material properties used in the stress-strain curves are shown in Table 3-2 (Reference 4).

Figure 34. Stress-Strain Curve for SB-171 90-10 Cu-NI 3.3 Boundary Conditions Figure 3-5 shows the model boundary conditions. The model is constrained at the following locations:
Transvcrsc (X-axis) motion is constrained at the model plane of symmetry.
Longitudinal (Z-axis) motion is constrained at the heat exchanger shell.
The edge of the partition plate engaged with the cover is constrained against vertical (Y-axis) motion.
The nozzle end nodes are coupled vertically (Y-axis) to ensure they remain in-plane vertically.

Prepared By Checked By Page: 10 0108-0309-JEM-1 7 _ l Revision: 0 Hydrostatic end loads are applied to the nozzles and the channel flange. The hydrostatic end load is calculated as follows:
F.e = PA, K'r, where:
Pdr = Heat Exchanger Internal Pressure r,
= Nozzle inside radius (Reference 1)
One half of this load (due to half-model) is applied as a pressure to the end of each nozzle and the channel flange.
The internal heat exchanger pressure is applied to all of the internal surfaces of the channel. The internal pressure applied to the tubesheet is modified to account for the misting volume of the tube penetrations as well as the stiffness of the tubes. Reference 8 calculates that the effective tubesheet pressure based on an internal pressure of 200 psi is 62 psi. This objective of this analysis is to calculate the collapse load of the heat exchanger channels. Therefore, a maximum pressure of 400 psi, which exceeds the re-rate design pressure of 200 psi, is applied. At an internal pressure of 400 psi, an effective pressure of 624(400/200)=l 24 psi will be applied to the tubesheet.

Revision: 0 4.0 ANALYSIS This calculation peiforms a Plastic Analysis of the CC heat exchanger channel using the methodology specified in Reference 7, Appendix 4, 4-136.4. This analysis does not attempt to certify that the heat exchanger meets the requirements of the ASME B&PV. Using the full stress-strain curve discussed above, a collapse load is calculated using the methodology described Reference 7, Appendix 6, 6-153. As the internal pressure is ramped up to a final arbitrary load of 400 psi, the deflection of the channel shell at a location remote fom discontinuities is plotted.
From this deflection vs. load data, a collapse limit line is plotted. The intersection of the deflection curve and collapse limit line is the collapse pressure. Per Reference 7, 4-136.4, the maximum loading of the component shall not exceed two-thirds of the plastic collapse load.
.4 With the deflection vs. load plotted with the load on the ordinate, the collapse limit tine is determined by first calculating the angle between the elastic portion of the deflection curvc and the ordinate (e). The angle between the collapse limit load and the ordinate (0) is calculated as follows:
P = tanN'(2tane) 4.1 Analysis Results Figures 4-1 and 4-2 show the stress intensity distribution of the channel at 200 psi and 400 psi, respectively. Review of these stress distributions indicates that the channel shell stress is primarily membrane stress and that no plastic hinges have been formed.
Figure 4-3 shows the deflection vs. load curve and the collapse limit line calculated in accordance with Reference 7, Appendix 6, 6-153 (See Appendix A for data). This data is taken at a point approximately midway between the tubesheet and flange (axially) and midway between the partition plate and upper nozzle repad. This is where the maximum shell displacement occurs.
The deflection vs. load curve on Figure 4-3 had not yet intersected with the collapse limit line at a pressure of 400 psi. Based on this, it is conservative to assume that the plastic collapse load is at least 400 psi. Given a plastic collapse load of 400 psi, the maximum heat exchanger channel load is 2/3 * (400 psi) - 267 psi. The displacement and strain at other locations, including the highest stress region, were also evaluated using this methodology. In all cases, the displacement data and collapse limit lines were essentially identical, supporting the 267 psi maximum heat exchanger channel load.
