39 ( Calculation No. 040711-02, Revision 0 Page 1 of 44 CSI TECHNOLOGIES, INC. IP2 CHECWORKS Power Uprate Analysis 1. Introduction This calculation documents the revision of the Indian Point Unit 2 CHECWORKS model to predict Flow-Accelerated Corrosion (F AC) wear rate changes due to Stretch Power Uprate (SPU). The Indian Point Unit 2 SPU will change feedwater and steam flow rates, temperatures, and enthalpies, which in tum change local chemistry values. All of these factors affect wear rates due to F AC. As a result of the uprate, some lines will experience accelerated rates ofFAC, while others will have reduced rates. The impact on each line depends on the complex interaction of changes in flow rate, pressure, temperature, enthalpy, steam quality, and chemistry on the F AC degradation mechanism.

Indian Point 2 had previously developed a CHECWORKS model ofF AC-susceptible piping. However, the previous model did not address the changes that will result from Appendix K Uprate and Stretch Power Uprate. This calculation details the process required to revise the CHECWORKS model so that it correctly reflects all plant power levels (the original power level, Appendix K Uprate, and Stretch Power Uprate). Also documented are the changes in F AC wear rates due to the SPU. Note that historical (pre-uprate and Appendix K Uprate) operating conditions remain within the model, associated to the applicable operating cycles. The SPU operating conditions are associated to the calendar time that those conditions are scheduled to occur, starting in Cycle 17 [7.3.1]. In this way, the model's predictions of total current and future wear will be as accurate as possible because the predictions will be based on both historical and expected future operating conditions.

4.2.1. The line on the CHECWORKS Heat Balance Diagram (HBD) representing the Moisture Separator/Moisture Preseparator drain lines was remodeled so the downstream connection of the line was the Heater Drain Tank instead of Feedwater Heater 25. The correct configuration was determined from flow diagrams [7.3.3] and the SPU heat balance diagram [7.1.3]. 4.2.2. The CHECWORKS HBD was corrected so that the steam driven Feed Pump supply originated in the Main Steam system upstream of LP Turbine as opposed to Main Steam upstream of the HP Turbine. Plant layout shows steam supply as coming from both locations; however, the SPU HBD shows that supply is from Main Steam upstream of LP Turbine under normal operating conditions

The overall flow rate, pressure, and enthalpy of these lines were calculated and entered in the CHECWORKS Steam Cycle (see Section 5.1.3). The combined flow rate was calculated as the sum of the liquid and steam flow rates (or the sum of multiple trains), the combined pressure was calculated as the average of all pressures, and the enthalpy was calculated as the weighted average of liquid and steam enthalpy (or the weighted average of multiple trains). These calculations were performed based on EPRI's Guidelines for Plant Modeling and Evaluation of Component Inspection Data [7.6]. 4.4. Plant period data was estimated for the cycle where the SPU will occur. Start and end dates were estimated based on anticipated dates [7.3.1].

( CSI TECHNOLOGIES, INC. IP2 CHECWORKS Power Uprate Analysis 5.5.3. Complete Advanced Run Defmition Form for Z-Type Lines Lines not associated to the CHECWORKS HBD are called Z-type lines. Because they are not associated to the HBD, CHECWORKS cannot automatically calculate chemistry and operating conditions for these lines. Therefore, when using the ARD function, the user must input not only flow factors and duty factors but also thermodynamic conditions, flow rate, and chemistry conditions for each operating cycle. Z-type lines were created due to limitations in the CHECWORKS HBD. In these cases, the computer model does not obtain the data from the correct location on the HBD, or the CHECWORKS program did not allow the correct data to be entered. For example, there is no global input into CHECWORKS to specify the pressure, temperature, enthalpy, or quality in feedwater heater drain lines. Instead the model calculates the conditions in the shell side drain as being equivalent to tube side heater outlet. This is incorrect, so the CHECWORKS HBD was not used as the source of operating conditions for heater drain lines. Instead, operating conditions for heater drain lines were entered on the ARD form.

Wear Rate Analysis was perfonned for two periods representing the original power level and the SPU power level. The water treatment for these two periods was modeled as identical, so wear rate changes are due to SPU conditions only. In both cases, Wear Rate Analysis was perfonned using Pass 2 methods, where predictions are calibrated to inspection history. The analysis obtained both actual results and percentage differences for representative components and lines so that detailed comparisons could be made. The analysis was limited to non-Chromium containing components only, so average values would not be skewed by these components.

RE: RAI FAC-1 Harry, There are no operational changes for Steam Plant Systems, such as use of additional trains or use of bypass lines not currently in operation, associated with uprate of IP2 / IP3. Changes due to the uprate which affect FAC are primarily changes in system f10wrates and temperatures, which are documented in the Heat Balance calculations.

Impact of these changes on piping velocities and temperatures is addressed in the applicable sections of the BOP Uprate Engineering Reports, forwarded to Entergy for review. Modifications associated with the uprate of IP2 / IP3 include: (1) MSR internal moisture separation system replacement, (2) HP Turbine rotor replacement, (3) HP turbine interstage drain piping modification, and (4) Relocation of HP turbine 1 st stage pressure taps.

Request for Additional HBDs CSI Doc. No. 04071137 Ron, Based on our discussion earlier today, it appears that we have some additional work to do on this end. We plan on modeling all three power levels (100% -the Original power level, -101.4% -the Appendix K power level, and 105% -the SPU power level) for each unit. In doing this, we will capture plant conditions at each point in history. To complete this task, we will need the following input: (1) Unit 3 PEPSE or HBD at -101.4% power (the Appendix K power uprate) (2) Unit 2 Original PEPSE or HBD at 100% power (pre-Appendix K) (3) Unit 3 Start date for the Appendix K Uprate (4) Unit 2 Start date for the Appendix K Uprate Please let me know if you have any questions.

39 ( Calculation No. 040711-02, Revision 0 Page 1 of 44 CSI TECHNOLOGIES, INC. IP2 CHECWORKS Power Uprate Analysis 1. Introduction This calculation documents the revision of the Indian Point Unit 2 CHECWORKS model to predict Flow-Accelerated Corrosion (F AC) wear rate changes due to Stretch Power Uprate (SPU). The Indian Point Unit 2 SPU will change feedwater and steam flow rates, temperatures, and enthalpies, which in tum change local chemistry values. All of these factors affect wear rates due to F AC. As a result of the uprate, some lines will experience accelerated rates ofFAC, while others will have reduced rates. The impact on each line depends on the complex interaction of changes in flow rate, pressure, temperature, enthalpy, steam quality, and chemistry on the F AC degradation mechanism.

Indian Point 2 had previously developed a CHECWORKS model ofF AC-susceptible piping. However, the previous model did not address the changes that will result from Appendix K Uprate and Stretch Power Uprate. This calculation details the process required to revise the CHECWORKS model so that it correctly reflects all plant power levels (the original power level, Appendix K Uprate, and Stretch Power Uprate). Also documented are the changes in F AC wear rates due to the SPU. Note that historical (pre-uprate and Appendix K Uprate) operating conditions remain within the model, associated to the applicable operating cycles. The SPU operating conditions are associated to the calendar time that those conditions are scheduled to occur, starting in Cycle 17 [7.3.1]. In this way, the model's predictions of total current and future wear will be as accurate as possible because the predictions will be based on both historical and expected future operating conditions.

Calculation No. 040711-02, Revision 0 Page 2 of 44

( \ ( " CSI TECHNOLOGIES, INC. IP2 CHECWORKS Power Uprate Analysis 2. Purpose The purposes of the power uprate analysis in CHECWORKS are as follows:

  • To gain the ability to describe the effects of power uprate on F AC-susceptible piping in the Licensing Submittal.
  • To ensure that the CHECWORKS model reflects current plant conditions going forward. Calculation No. 040711-02, Revision 0 Page 3 0(44

( " CSI TECHNOLOGIES, INC. IP2 CHECWORKS Power Uprate Analysis 3. Scope The scope of this power uprate analysis was determined from the input Indian Point 2 CHECWORKS model [7.2]. However, not all lines and components in the input model were included in this analysis.

Only those lines and components that were assigned to one of the Wear Rate Analysis run definitions in Table 1.0 of document number 00130-TR-OOI were analyzed as part of this project [7.10]. The CHECWORKS model also contains "non-modeled" lines and components (typically assigned to CHECWORKS lines with the prefix NCW for "Non-CHECWORKS").

No analysis was performed on these "NCW" lines or any other plant lines and components that were not part of the "official" CHECWORKS model. Note that Table 1.0 of document 00130-TR-OOI has two hand-written entries "x-under wi exp joints" and "CND FWH 22 to FWH 23" [7.10]. Lines and components that belong in these two locations were also included in this analysis.

This analysis was performed using CHECWORKS FAC version 1.0G. Assumptions and modeling decisions made during this analysis are documented in Section 4. The methodology employed during this analysis is detailed in Section 5. Results obtained are listed in Section 6 and in the Appendices.

Finally, Section 7 includes a list of all references used in this analysis.

Calculation No. 040711-02, Revision 0 Page 4 of 44

( CSI TECHNOLOGIES, INC. W2 CHECWORKS Power Uprate Analysis 4. Assumptions and Modeling Decisions The following assumptions and modeling decisions apply to the updated CHECWORKS model. 4.1. All data in the CHECWORKS model received as input (the as-received model) [7.2] was assumed to be complete and accurate.

4.2. Exceptions

were made to Assumption 4.1 in the following cases. These exceptions appear in this section, as they are not a standard part of a CHECWORKS power uprate analysis.

4.2.1. The line on the CHECWORKS Heat Balance Diagram (HBD) representing the Moisture Separator/Moisture Preseparator drain lines was remodeled so the downstream connection of the line was the Heater Drain Tank instead of Feedwater Heater 25. The correct configuration was determined from flow diagrams [7.3.3] and the SPU heat balance diagram [7.1.3]. 4.2.2. The CHECWORKS HBD was corrected so that the steam driven Feed Pump supply originated in the Main Steam system upstream of LP Turbine as opposed to Main Steam upstream of the HP Turbine. Plant layout shows steam supply as coming from both locations; however, the SPU HBD shows that supply is from Main Steam upstream of LP Turbine under normal operating conditions

[7.1.3]. 4.2.3. Reheat Steam to the Moisture Separator Reheater on the CHECWORKS HBD was remodeled so the source was from the Main Steam system upstream ofthe HP Turbine as opposed to downstream ofthe HP Turbine. The correct configuration was determined from flow diagrams [7.3.3] and the SPU heat balance diagram [7.1.3]. 4.2.4. The condensate pump was added to the CHECWORKS HBD; the condensate pump had been omitted previously.

4.2.5. The input CHECWORKS model did not have components in the Condensate system between Feedwater Heaters 22 and Feedwater Heaters 23. All components in these lines were modeled as part of this analysis.

Component information and configuration was determined by using the existing F AC isometric for Unit 3 as a guide [7.8]. Lines were named using Sketch 80A as the sketch number. The F AC Program Owner supplied component names [7.9]. 4.2.6. An error stating, "The input hydrazine cone. at SO Steam outlet caused a mass in-balance in the Water Chemistry Analysis" was generated when performing water chemistry analysis for Cycle 14. The hydrazine Calculation No. 040711-02, Revision 0 Page 5 of 44

( \. CSI TECHNOLOGIES, INC. IP2 CHECWORKS Power Uprate Analysis concentration at the Steam Generator Outlet was lowered from 18 ppb to 15 ppb for this water treatment.

This action enabled water chemistry analysis to run without error. 4.2.7. The hydrazine concentration at the SG outlet and MSR drain locations were not specified for Cycle 16 water treatment.

If this data is not entered, CHECWORKS calculates a concentration of zero at these locations.

Therefore, estimated hydrazine concentrations were entered at these locations by using the "rules of thumb" for a Recirculating Steam Generator

[7.6]. Based on the "rules of thumb", the concentration of hydrazine at the Steam Generator Outlet was assumed to be 60% of the final feedwater concentration, while the concentration ofhydrazine at the MSR Drain was assumed to be 120% of the final feedwater concentration.

4.2.8. During

WRA, an error message appeared for component MS-IBI4P-l US stating that, "Orifice size 5.761" cannot be greater than pipe inside diameter 5.611 "". The initial thickness of this component (0.507") was deleted; nominal thickness was then used in this calculation.

WRA was able to proceed without further error. 4.3. For a number of lines on the SPU Heat Balance Diagram [7.1.3] and Appendix K Heat Balance Diagram [7.1.2], thermodynamic and flow values (pressure, enthalpy, and flow rate) were listed separately for the steam phase and the water phase or for each train in a parallel train configuration.

The overall flow rate, pressure, and enthalpy of these lines were calculated and entered in the CHECWORKS Steam Cycle (see Section 5.1.3). The combined flow rate was calculated as the sum of the liquid and steam flow rates (or the sum of multiple trains), the combined pressure was calculated as the average of all pressures, and the enthalpy was calculated as the weighted average of liquid and steam enthalpy (or the weighted average of multiple trains). These calculations were performed based on EPRI's Guidelines for Plant Modeling and Evaluation of Component Inspection Data [7.6]. 4.4. Plant period data was estimated for the cycle where the SPU will occur. Start and end dates were estimated based on anticipated dates [7.3.1]. An estimation of operating hours was calculated from these dates based on calendar days. The Water Treatment for this cycle was modeled as equivalent to the most recent complete operating cycle. The model can be updated with actual values for these inputs when this data becomes available.

4.5. Due to the use of the Advanced Run Definition feature in this model, which is required for accurate modeling of the power uprate condition, CHECWORKS F AC Version 1.0G cannot accurately represent the operating conditions in tees that combine or split flow. In order to maintain simplicity in the CHECWORKS model, tees were modeled with a flow rate equal to the highest flow rate present in Calculation No. 040711-02, Revision 0 Page 6 of 44 CSI TECHNOLOGIES, INC. IP2 CHECWORKS Power Uprate Analysis ( the tee. Therefore, the predicted wear rates for tees should be used with caution. ( " Calculation No. 040711-02, Revision 0 Page 70f44

( CSI TECHNOLOGIES, INC. IP2 CHECWORKS Power Uprate Analysis 5. Methodology Additional input data was entered into the CHECWORKS model to model the power uprate. A number of tasks were required to convert the previous Indian Point Unit 2 model into a format that was compatible with a power uprate. The following section describes the tasks performed to enter power uprate data and to convert the model into a form compatible with multiple power levels. 5.1. Input SPU Global Data Additional CHECWORKS Power Levels representing the SPU and Appendix K operating conditions were defined in the model and associated to the applicable Plant Period. The following sections detail the steps involved in this task. 5.1.1. CHECWORKS Heat Balance Diagram The CHECWORKS Heat Balance Diagram (HBD) was reviewed to ensure that it correctly portrayed plant configuration.

The CHECWORKS HBD was compared to the plant Heat Balance Diagrams [7.1] and flow diagrams [7.3.3]. Discrepancies were noted and corrected as discussed in Section 4.2. 5.1.2. Power Level Data A Plant Power Level is defined for each power level at which the plant is operated for a significant period of time. Two new power levels were added to the model representing the SPU and Appendix K conditions.

Table 5.1 lists all power levels in the model and the operating cycles to which they apply. Table 5.1 Power Level History Power Power Operating Cycles Notes Level (%) (MWt) 100.00 3090.2 Cycles 1-16A Original Power Level 101.19 3127.0 Cycle 16B Appendix K Uprate 104.48 3228.5 Cycle 17 to End of Life Stretch Power Uprate Data was entered for the new power levels on the Power Level Form in accordance with the CHECWORKS User's Guide [7.5].

Steam phase enthalpy was obtained directly from the PEPSE diagram as the enthalpy after moisture removal in the LP Turbine. Liquid phase enthalpy was calculated as the enthalpy of saturated liquid at the pressure given on the PEPSE diagram. 5.1.4. Plant Period Data Each power level identified in Table 5.1 was associated to the correct operating cycle or cycles. The Appendix K Uprate start date was obtained through correspondence with plant personnel

[7.3.3]. The SPU is scheduled for the start of Cycle 17. To include this power level in the model , plant periods were created that have not yet occurred.

Redefinition of CHECWORKS Lines The CHECWORKS model was prepared for use of the Advanced Run Definition (see Section 5.5). This task consisted of redefining the CHECWORKS lines within the model so that all components on a given line are subject to the same thermodynamic conditions.

Appendix A contains a listing of all lines that appear in the CHECWORKS model. For conservatism, the tee where flow rate changed was associated to the line having the greatest flow rate. Note that the model will over-predict the wear for some sections oftees (see Section 4.5). Figure 5-1 illustrates the procedure used to group components into lines. In the diagram, seven lines exist, each with a different percentage of the total flow. Note that the tee is grouped with the line number seeing the greatest percentage of flow.

( ( CSI TECHNOLOGIES, INC. IP2 CHECWORKS Power Uprate Analysis 5.3. 5.4. Components were grouped into lines by comparing the input CHECWORKS model [7.2] with FAC isometrics

[7.7] and flow diagrams [7.3.3]. New lines were given names according to the naming convention, below. AABBC-D-E AA Abbreviation of the system (ex: CD = Condensate, EX = Extraction Steam, etc.) BB Sketch number the line begins on (ex: 01, 80, etc.) C = Sketch letter if sketch number includes a letter (ex: A for sketch 80A) D Sequential number for each line on one sketch, numbered in flow order E Brief description of the line New line names were created as required by CHECWORKS, not where plant line names changed. Therefore, lines may contain components located on different sketches but in all cases the sketch number corresponds to the first component in the line. For example, line name "CDSO-I-FWH 23A to FWH 24A" is located in the Condensate system, on F AC sketch SO, and runs from Feedwater Heater 23A to Feedwater Heater 24A. Update Model Based on SPU Operational or Configuration Changes With an uprate in power, lines with partial operation may increase or decrease their operation frequency (such as additional trains in operation or bypass lines now operated during full power). Additionally, uprates may call for design changes that may result in piping configuration changes. No operational or configuration changes occurred due to the SPU [7.3.2]. Update Network Flow Analysis Definitions Network Flow Analysis (NF A) is a module within CHECWORKS that calculates flow rate, pressure drops, temperature changes, and steam quality changes based on piping configuration and source/sink conditions.

NF A is used where operating conditions are not completely known. A different set of source/sink conditions is entered for each NF A per power level. Additional input data must be added to each NF A to reflect the SPU power level identified in Section 5.1.2. The Indian Point 2 CHECWORKS model did not contain any NF A definitions; therefore, no updates to the model were performed during this task [7.2]. 5.5. Implement the Advanced Run Definition This task involved a redefinition of the source in which CHECWORKS obtains thermodynamic conditions (pressure, enthalpy, temperature, and quality) and flow rate conditions for a component.

Previously all thermodynamic and flow rate conditions had been entered individually for each component on the component data forms. However, the component form allows only one set of thermodynamic Calculation No. 040711-02, Revision 0 Page 13 of 44

( i \ CSI TECHNOLOGIES, INC. IP2 CHECWORKS Power Uprate Analysis and flow rate conditions to be entered (i.e. from one power level). Therefore, use of the component fonn as the input for thermodynamic and flow rate conditions is not valid, as it does not reflect both pre-uprate and post-uprate conditions.

Instead, thermodynamic and flow conditions were entered globally (see Section 5.1) and linked to components through the association of a line to the CHECWORKS HBD (except Z-type lines). The following sections detail the steps performed to implement the Advanced Run Definition.

5.5.1. Enter

Flow Factors On the CHECWORKS HBD level, flow rates are expressed in totals rather than for each train. For example, feedwater flow rate might be entered as 10 million pounds per hour, where each train of a three-train system sees 3.33 million pounds per hour. As a result, flow multipliers had to be entered for the lines so that the actual flow rate is used to calculate wear rate at the component level. Thus for each line a flow multiplier, or flow factor, was calculated.

The flow factor is used to adjust the CHECWORKS HBD calculated flow rate. The calculated flow factor for each line was entered on the ARD form. There are some exceptions to the use of flow factors. The first is for lines and flow segments where NF A would be used to calculate operating conditions and flow rate. For these the train flow is directly entered into the NF A definitions. Therefore, these lines the assigned flow factor is 1.0. Other exceptions are made for some lines and flow segments where the ARD form is used as the source of operating conditions.

In some cases, if the input source (PEPSE or HBD) already listed flow rate per train, then the flow factor is set to 1.0 and the train flow rate is entered. Flow factors were calculated by consulting the CHECWORKS HBD, the plant heat balance diagrams [7.1], and the flow diagrams [7.3.3]. Flow factors for each line appear in Appendix A. 5.5.2. Enter Duty Factors The duty factor is used to specify the fraction of the total plant operating hours that a given line was in operation.

For full-time lines, the duty factor is 1.0. For part-time lines, the duty factor is set to a value less than one based on operation.

For example, if a line has full flow half of the time and zero flow half of the time, then the lines would be modeled with full flow and the duty factor would be set to 0.5. Use ofthe duty factor is in accordance with the recommendations of the EPRI Guidelines for Plant Modeling and Evaluation of Component Inspection Data [7.6]. Duty factors were taken from the input CHECWORKS model [7.2]. Duty factors for each line appear in Appendix A. Calculation No. 040711-02, Revision 0 Page 14 of 44

( CSI TECHNOLOGIES, INC. IP2 CHECWORKS Power Uprate Analysis 5.5.3. Complete Advanced Run Defmition Form for Z-Type Lines Lines not associated to the CHECWORKS HBD are called Z-type lines. Because they are not associated to the HBD, CHECWORKS cannot automatically calculate chemistry and operating conditions for these lines. Therefore, when using the ARD function, the user must input not only flow factors and duty factors but also thermodynamic conditions, flow rate, and chemistry conditions for each operating cycle. Z-type lines were created due to limitations in the CHECWORKS HBD. In these cases, the computer model does not obtain the data from the correct location on the HBD, or the CHECWORKS program did not allow the correct data to be entered. For example, there is no global input into CHECWORKS to specify the pressure, temperature, enthalpy, or quality in feedwater heater drain lines. Instead the model calculates the conditions in the shell side drain as being equivalent to tube side heater outlet. This is incorrect, so the CHECWORKS HBD was not used as the source of operating conditions for heater drain lines. Instead, operating conditions for heater drain lines were entered on the ARD form. Appendix A lists all the lines in the model and includes whether or not the line is a Z-type line. For Z-type lines, thermodynamic data and flow rate was obtained from the Heat Balance Diagrams [7.1]. 5.5.4. Set Wear Rate Analysis Source of Data Option The CHECWORKS model allows the user to specify the source of component operating conditions.

Component operating conditions can come from one of four locations:

the CHECWORKS HBD, the Component form, an NF A, or the ARD. During wear rate analysis, CHECWORKS can use the operating conditions stored at the component level ("COMP"), determine the operating conditions based upon steam cycle data and Advanced Run Definition Flow Factors ("HBD"), use the operating conditions entered on the Advanced Run Definition form only ("ARD"), or to use the operating conditions calculated using an NF A ("NFA"). For all cases, the option "NFA->HBD->ARD->COMP" was selected.

This directs CHECWORKS to preferentially use Network Flow Analysis first (if it exists for the line), followed by the ARD (for Z-type lines), the HBD (for all remaining lines), and finally the component.

The option "NFA->HBD->ARD->COMP" was selected for all lines since the model includes multiple power levels. 5.6. Perform Wear Rate Analysis Wear Rate Analysis (WRA) is a module within CHECWORKS that provides predicted wear rates and remaining service lives for each modeled component.

WRA was run on every component so that the predicted wear rates include the Calculation No. 040711-02, Revision 0 Page 15 of 44 ,----------------

WRA includes an error-trapping routine, so that discrepancies will be identified and corrected.

WRA was perfonned successfully without error. Quantify Effect of Stretch Power Uprate An analysis was perfonned to calculate the change in CHECWORKS predicted wear rates due to the SPU conditions.

Wear Rate Analysis was perfonned for two periods representing the original power level and the SPU power level. The water treatment for these two periods was modeled as identical, so wear rate changes are due to SPU conditions only. In both cases, Wear Rate Analysis was perfonned using Pass 2 methods, where predictions are calibrated to inspection history. The analysis obtained both actual results and percentage differences for representative components and lines so that detailed comparisons could be made. The analysis was limited to non-Chromium containing components only, so average values would not be skewed by these components.

In addition the changes due to SPU for some of the dominant parameters affecting F AC wear rates (temperature, steam quality, and flow rate) were detennined.

An analysis was perfonned on a sample of some of the components in the model most susceptible to FAC. Pass 2 Wear Rate Analysis was perfonned at the uprate, original power level and the SPU power level. The samples were determined as follows:

  • The five components in the model with the highest wear rates for the original, pre-uprate power level were selected.
  • The five components that experienced the greatest percent increase in wear rate due to the SPU (excluding chromium containing components).

The results of this analysis appear in Appendix B Steam Cycle Level Wear Rate Changes due to SPU An analysis was perfonned comparing Steam Cycle Level changes in wear rate predictions due to the SPU. Lines with similar thennodynamic conditions were grouped together and the average component wear rate was calculated for each grouping, called a Steam Cycle Location.

In addition some of the dominant parameters affecting FAC wear rates (temperature, steam quality, and flow rate) were detennined.

The results of this analysis appear in tabular fonn in Appendix C. In addition, results are summarized on a steam cycle drawing in Appendix C. Calculation No. 040711-02, Revision 0 Page 17 of 44

Dan: Attached is the response from our engineer, the Shaw Group to your request for a listing of all operational and/or configuration changes due to the SPU. Note that there are no operational and/or configuration changes to IP2IIP3 due to the SPU. This information was required for DDIR NO.6 and 7. Per your request, a hard copy set of IP3 FAC isometric drawings will be mailed today to your attention.

Note that drawing EC-H-50077 is not yet revised in this mailing. For correct piping configuration, see the information I sent you for the 3R12 Checworks update. Included in this mailing is: 1. Flow Accelerated Corrosion Program Checworks Analysis Enhancement, Technical Report No. 00130-TR-001 Revision 0 Volume 1 of 1. December, 2000. This report serves as the Unit 2 Checworks Model documentation. In addition to the Checworks Wear Rate Analysis Run Definitions listed in Table 1.0, there are the following two additions:

a. X-under w/exp joints b. CND FWH 22 to FWH 23; this was added due to the SPU. This information was required for DDIR No.4 Harry Hartjen From: Cunningham, Glenn [1]

RE: RAI FAC-1 Harry, There are no operational changes for Steam Plant Systems, such as use of additional trains or use of bypass lines not currently in operation, associated with uprate of IP2 / IP3. Changes due to the uprate which affect FAC are primarily changes in system f10wrates and temperatures, which are documented in the Heat Balance calculations.

Impact of these changes on piping velocities and temperatures is addressed in the applicable sections of the BOP Uprate Engineering Reports, forwarded to Entergy for review. Modifications associated with the uprate of IP2 / IP3 include: (1) MSR internal moisture separation system replacement, (2) HP Turbine rotor replacement, (3) HP turbine interstage drain piping modification, and (4) Relocation of HP turbine 1 st stage pressure taps.

RE: RAI FAC-1 Glen: IP2 CHECWORKS Power Uprate Analysis This is to confirm that the wear rate comparison will be completed by 12/31/2004.

As I mentioned to you we are having a contractor perform the update to our Checworks models. One of the inputs I have to provide to them is: The listing of all Unit 2 and Unit 3 operational and/or configuration changes due to the power uprate (Le., additional trains in operation, bypass lines operated at full power, etc.) Do you have this information or can you direct my question to someone who has this information.

Request for Additional HBDs CSI Doc. No. 04071137 Ron, Based on our discussion earlier today, it appears that we have some additional work to do on this end. We plan on modeling all three power levels (100% -the Original power level, -101.4% -the Appendix K power level, and 105% -the SPU power level) for each unit. In doing this, we will capture plant conditions at each point in history. To complete this task, we will need the following input: (1) Unit 3 PEPSE or HBD at -101.4% power (the Appendix K power uprate) (2) Unit 2 Original PEPSE or HBD at 100% power (pre-Appendix K) (3) Unit 3 Start date for the Appendix K Uprate (4) Unit 2 Start date for the Appendix K Uprate Please let me know if you have any questions.

We will be contacting Harry to inform him of this plan. Thank you, Brian Trudeau CSI Technologies, Inc. (847) 836-3000 ext. 717 (, www.csitechnologies.com Calculation No. 040711-02, Attachment A, Revision 0 Page 44 of44
