IP3 CHECWORKS Power Uprate Analysis

1.

Introduction This calculation documents the revision of the Indian Point Unit 3 CHECWORKS model to predict Flow-Accelerated Corrosion (FAC) wear rate changes due to Stretch Power Uprate (SPU). The Indian Point Unit 3 SPU will change feedwater and steam flow rates, temperatures, and enthalpies, which in turn change local chemistry values. All of these factors affect wear rates due to FAC. As a result of the uprate, some lines will experience accelerated rates of FAC, 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 FAC degradation mechanism.

Indian Point 3 had previously developed a CHECWORKS model of FAC-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 FAC 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 14 [7.3.1]. In this way, the models 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.

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.

An exception was made to Assumption 4.1 in one case. The CHECWORKS HBD in the input model had the Boiler Feed Pump modeled as an electric pump instead of a steam driven pump. The CHECWORKS HBD was corrected to portray the Boiler Feed Pump as a steam driven pump.

4.3.

Because the Boiler Feed Pump was remodeled as a steam driven pump as discussed in Section 4.2, Steam Cycle Data was input for the original power level in addition to the Appendix K and SPU power levels for this location. Flow rate was obtained from the original HBD [7.1.1]. Feed Pump Turbine drain pressure and enthalpy was not shown on the original HBD; therefore, the original pressure and enthalpy was assumed to be equivalent to the SPU pressure and enthalpy as shown on the SPU HBD [7.1.3]. Note that this assumption has little impact on the model as no components in the Feed Pump Turbine drain are modeled.

4.4.

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 EPRIs Guidelines for Plant Modeling and Evaluation of Component Inspection Data [7.6].

4.5.

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.

4.6.

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 Calculation No. 040711-01, Revision 0 Page 5 of 44

FAC Version 1.OG 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 the tee. Therefore, the predicted wear rates for tees should be used with caution.

The flow rate in the Feedwater Pump Recirculation lines was shown as zero on the SPU Heat Balance [7.1.3] and Appendix K Heat Balance C7.1.21. In general flow through such lines is zero under normal operation, so a heat balance is not a good source for determining this flow. Therefore, an assumption was made that the flow rate under SPU and Appendix K conditions was equivalent to the flow rate under original pre-uprate conditions as defined in the input CHECWORKS model (the as-received model) [7.2]. Note that all components in these lines are constructed with FAC-resistant material, so this assumption has little to no impact on wear rate predictions.

IP3 CHECWORKS Power Uprate Analysis 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.

AA-BB.CC D AA

= System Abbreviation BB.CC = Multi-digit code to identifl a plant line or location D

= Brief line description Note that the AA-BB.CC portion of the line name corresponds to the plant line name and component name prefix as taken from the flow diagrams [7.3.3] and FAC isometrics [7.7]. New line names were created as required by CHECWORKS, not where plant line names changed. Therefore, some lines contain components with different component name prefixes, but in general the component prefix and line name agree. Note that if the AA-BB.CC portion of the line name was not unique for CHECWORKS purposes, an underscore followed by a 1,2,3 etc. was added to this portion of the line name.

For example, line name CD-01.lA FWH 3 1A to F W H 32A is plant line name CD-O1.lA in the Unit 3 Condensate system from Feedwater Heater 3 1A to Feedwater Heater 32A.

Update Model Based on SPU Operational or Configuration Changes With an uprate in power, lines with partial operation may increase or decrease their operation fiequency (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 occuTed due to the SPU [7.3.2].

Update Network Flow Analysis Definitions Network Flow Analysis (NFA) 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. NFA is used where operating conditions are not completely known. A different set of source/si& conditions is entered for each NFA per power level. Additional input data must be added to each NFA to reflect the SPU and Appendix K power levels identified in Section 5.1.2.

The Indian Point 3 CHECWORKS model did not contain any NFA definitions; therefore, no updates to the model were performed during this task [7.2].

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 and flow rate conditions to be entered (i.e. from one power level). Therefore, use of the component form 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.

5.5.2.

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 NFA would be used to calculate operating conditions and flow rate. For these the train flow is directly entered into the NFA definitions. Therefore, these lines the assigned flow factor is 1.O.

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.O 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.

Enter Duty Factors The duty factor is used to specie the fraction of the total plant operating hours that a given line was in operation. For full-time lines, the duty factor is 1.O. 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.

Implement the Advanced Run Definition This task involved a redefinition of the source in which CHECWORKS obtains thennodynamic conditions (pressure, enthalpy, temperature, and quality) and flow rate conditions for a component. Previously all thennodynamic and flow rate conditions had been entered individually for each component on the component data fonns. However, the component fonn allows only one set ofthennodynamic 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 RBD (except Z-type lines). The following sections detail the steps perfonned to implement the Advance4 Run Definition.

5.5.1. Enter Flow Factors On the CHECWORKS RBD 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 RBD calculated flow rate. The calculated flow factor for each line was entered on the ARD fonn.

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 fonn is used as the source of operating conditions. In some cases, if the input source (PEPSE or RBD) 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 CRECWORKS RBD, 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.

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.

Complete Advanced Run Definition 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 hction, 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].

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 NFA, 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 NFA (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.

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.

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.

("ARD"), or to use the operating conditions calculated using an NFA

("NF A"). For all cases, the option "NF A->HBD->ARD->COMP" was selected. This directs CHECWORKS to preferentially use Network Flow Analysis first (ifit exists for the line), followed by the ARD (for Z-type lines), the HBD (for all remaining lines), and finally the component.

Quanti@ Effect of Stretch Power Uprate An analysis was performed to calculate the change in CHECWORKS predicted wear rates due to the SPU conditions. Wear Rate Analysis was performed 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 performed 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 FAC wear rates (temperature, steam quality, and flow rate) were determined.

Results 6.1.

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

0 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).

0 The results of this analysis appear in Appendix B 6.2.

Steam Cycle Level Wear Rate Changes due to SPU An analysis was performed comparing Steam Cycle Level changes in wear rate predictions due to the SPU. Lines with similar thermodynamic 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 determined. The results of this analysis appear in tabular form in Appendix C. In addition, results are summarized on a steam cycle drawing in Appendix C.

(5) Values in GREEN show where flow rate has decreased while values in RED show where flow rate has increased. FAC rates increase with looreasing flow rates and decrease with decreasing flow rates.

IP3 CHECWORKS Power Uprate Analysis Reference 7.3.2 Email from Harry Hartjen (IP3) to Daniel R. Poe (CSI Technologies), dated 10/18/2004, regarding operational and configuration changes due to SPU, CSI Doc. No. 04071 113.

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 IPUIP3 due to the SPU.

This information was required for DDlR 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.

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.O, there are the following two additions:

Flow Accelerated Corrosion Program Checworks Analysis Enhancement, Technical

a.

X-under wlexp joints

b.

CND FWH 22 to FWH 23; this was added due to the SPU.

Subject:

RE: RAI FAC-1 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 flowrates 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"stage pressure taps.

RE: RAI FAC-1 Glen:

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 (i.e.,

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.

CSI Doc. No. 04071 137

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 (1 00% - the Original power level, -1 01.4% - 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.
