CSI TECHNOLOGIES, INC. Indian Point 2 FAC System Susceptibility Evaluation (SSE)

1. Introduction Flow-Accelerated Corrosion (FAC) is a form of material degradation that results in thinning of the inside pipe wall in carbon steel piping and fittings under certain flow and chemistry conditions. If undetected, FAC may result in piping rupture and subsequent fatalities, injuries, equipment damage, unplanned plant shutdown, and transients that pose undesirable challenges to plant operators. Consequently, all US nuclear plants, including Indian Point, have FAC programs in place to detect and mitigate FAC before piping failure in accordance with Generic Letter 89-08 [7.1].

An effective FAC program includes three key elements: the System Susceptibility Evaluation (SSE), which defines and controls the program scope; the CHECWORKS computer model, which predicts wear rates for every modeled component; and the Susceptible Non-Modeled (SNM) Program, which prioritizes non-modeled but susceptible lines according to FAC potential.

CSI TECHNOLOGIES, INC. Indian Point 2 FAC System Susceptibility Evaluation (SSE)

2. Purpose This document contains the development and results of an FAC System Susceptibility Evaluation (SSE) for Indian Point Energy Center Unit 2. Each plant system, subsystem, and line is classified as either susceptible or non-susceptible to FAC. Susceptible piping forms the scope of the Indian Point FAC program, while non-susceptible piping is excluded from the FAC program. Susceptible piping is further categorized as either modelable in the EPRI computer program CHECWORKS Steam/Feedwater Application (SFA) or non-modelable. Susceptible Non-Modeled (SNM) piping falls outside the capabilities of CHECWORKS SFA.

The purpose of this document is to:

• Define the scope of the Flow-Accelerated Corrosion (FAC) program.

• Identify all plant lines to be modeled in the EPRI computer program CHECWORKS Steam/Feedwater Application (SFA).

• Identify all plant lines that form the scope of the Susceptible Non-Modeled (SNM) program.

3. Scope The scope of this System Susceptibility Evaluation is all plant piping. This includes piping in all systems, subsystems, and lines. This document reflects the current operating status of the plant. Periodic review and update of this document is recommended by EPRIS Recommendations for an Effective Flow-Accelerated Corrosion Program, NSAC 202L [7.2].

Section 4 of this document contains a record of all assumptions made. Section 5 describes the methodology employed in this analysis. The results obtained are documented in Section 6 and in the Appendices. Finally, Section 7 includes a list of all references used in this analysis.

4. Assumptions 4.1. General Assumptions The following assumptions apply to all plant systems, subsystems, or lines.

4.1.1. Piping with nominal pipe size less than or equal to 2 is assumed to be socket welded. Likewise, lines over 2 in diameter are assumed butt-welded.

4.1.2. If piping material is unknown, carbon steel material is assumed.

4.1.3. If a portion of a system, subsystem, or line is susceptible, then the entire system, subsystem, or line is considered susceptible. An exception is made for lines where valves are the only susceptible components. Since valves are inspected by the Preventative Maintenance or Corrective Action programs, they are considered outside the FAC program.

4.1.4. Lines on the Indian Point P&IDs [7.3] containing normally closed valves are assumed to operate less than 2% of the time. Likewise, lines containing valves that are normally open are assumed to operate greater than 2% of the time. This assumption is used when specific valve information is not found in the System Descriptions [7.4], Plant Operating Manuals [7.5], or responses to questions by Indian Point personnel [7.6].

4.1.5. It is assumed that no normally closed valves leak, unless confirmed otherwise by plant operating history.

4.1.6. Lines that exist in non-susceptible systems or subsystems are excluded from further analysis on the system or subsystem level, respectively.

These lines may or may not appear in the Appendices.

4.2. System, Subsystem, and Line Specific Assumptions Assumptions and susceptibility decisions made specifically for a single system, subsystem, or line appear in the Comments field of the Susceptibility Evaluation reports in the Appendices.

4.2.1. Instrumentation, level control lines, and indicator lines are assumed to have insufficient flow to be susceptible to FAC.

4.2.2. Floor drains, miscellaneous capped drain and vent lines, and miscellaneous vent lines to the atmosphere are assumed to have insufficient flow to be susceptible to FAC (or operate infrequently).

4.2.3. Multiple line names are used for the same line in cases where susceptibility changed along the line and in cases where relationships to CHECWORKS are simplified by separating sections of lines.

Report No. 0700.104-02, Revision 2 Page 5 of 19

CSI TECHNOLOGIES, INC. Indian Point 2 FAC System Susceptibility Evaluation (SSE) 4.2.4. The supply and return headers for multiple unit heaters, lines 2-UH-003 and 2-UH-071, are continued on a drawing that could not be located by Indian Point personnel. The continuations of these lines, as well as any lines fed by these headers should be considered FAC-susceptible until proven otherwise.

4.2.5. It is assumed that Boiler Feed Pump seal water lines from the Condensate system do not increase to above 200ºF when passing through the Boiler Feed Pumps.

4.2.6. Judging by the flow configuration on drawing A209775 [7.3], the header containing steam from several unit heaters (24UHR, 211UHR, 219UHR, 221UHR), steam traps (UHT-2-2, UHT-4-1), and the oil preheater does not appear to have an outlet. If an outlet exists that is not shown on the drawing, it should be assumed susceptible to FAC until proven otherwise through further evaluation.

4.2.7. Judging by the flow configuration on drawing B193201 [7.3], lines 2-UH-002 and 2-UH-079 appear to have no inlet. If an inlet exists that is not shown on the drawing, it should be assumed susceptible to FAC until proven otherwise by further evaluation.

5. Methodology The methodology employed in this analysis consisted of a number of successive steps.

Each step is explained in detail in the following sections. A flowchart of the methodology used is included in the Figure 5.1 Each plant system, subsystem, and line was reviewed against FAC susceptibility criteria and CHECWORKS modelability criteria (as defined in Section 5.1 and Section 5.2) to determine its susceptibility category. If an entire system or subsystem was determined to be non-susceptible, a line-by-line review was not conducted; however, where that was not the case, each line was evaluated and categorized accordingly and individually.

CSI TECHNOLOGIES, INC. Indian Point 2 FAC System Susceptibility Evaluation (SSE) 5.1. Susceptibility Exclusion Criteria The criteria used to determine susceptibility to FAC was taken from Section 4.2 of EPRI NSAC 202L [7.2]. Systems, subsystems, and/or lines are not considered susceptible to FAC if one or more of the conditions discussed below apply.

5.1.1. FAC Resistant Material Stainless steel or low-alloy steel with chromium content equal or greater than 1.25% are FAC-resistant [7.2 and 7.7]. Lines or systems made, or replaced with, such materials are not sufficiently susceptible to FAC to warrant further analysis. It should be noted, however, that resistance to FAC does not ensure against other corrosion mechanisms such as cavitation or impingement. Therefore, even if components are replaced with FAC-resistant material, the root cause of wear should be determined before excluding the replaced components from the inspection program.

Wholesale replacement of a line with FAC resistant material would cause that line to be excluded from the FAC program. However, if one component on a line is susceptible, then the whole line was considered susceptible.

Piping material was obtained from the Piping Specifications [7.8], P&IDs

[7.3], or the Indian Point isometric drawings [7.9].

5.1.2. Superheated Steam Piping transporting superheated steam with no moisture content was classified as non-susceptible. According to EPRIs Recommendations for an Effective Flow-Accelerated Corrosion Program, FAC is known to occur only under flowing water or wet steam conditions, and has not been documented in superheated steam piping [7.2].

Steam quality was obtained from the PEPSE Model [7.10] first, followed by the operating conditions found in the Piping Specification [7.8].

5.1.3. Single-Phase Piping at Low Temperature Piping with single-phase flow and an operating temperature below 200oF does not experience FAC and was classified as non-susceptible. No temperature exclusion exists for two-phase lines [7.2]. Other degradation mechanisms, such as cavitation, may occur at low temperatures but such mechanisms are outside the scope of this analysis.

Operating temperature was obtained from the PEPSE Model [7.10] first, followed by the operating conditions found in the Piping Specification

[7.8].

5.1.4. Low Operating Frequency Piping that operates less than 2% of the plant operating time was deemed non-susceptible. In general, such piping does not experience the amount of flow required to make FAC a legitimate concern and is excluded from further analysis in favor of piping with greater FAC susceptibility. Piping Report No. 0700.104-02, Revision 2 Page 8 of 19

CSI TECHNOLOGIES, INC. Indian Point 2 FAC System Susceptibility Evaluation (SSE) in this category includes lines with normally closed valves and those feeding or emerging from equipment that operate less than 2% of the plant operating time.

Exceptions to this rule are made when the operating frequency may be low, but the service is especially severe [7.2].

All lines excluded due to infrequent operation would be susceptible to FAC if operating frequency is increased above the 2% threshold.

Therefore, if operating frequency is increased, these lines should be reviewed for inclusion in the FAC Program.

Operating frequency was determined by information from Plant Operating Manuals [7.5], by information found in the System Descriptions [7.4],

responses to questions by Indian Point personnel [7.6], and by valve position on the P&IDs [7.3]. See Assumption 4.1.3 for more details.

5.1.5. Combination Single-Phase Piping with Low Temperature and Operating Frequency This category is a derivative of the two previous susceptibility criteria described in Sections 5.1.3 and 5.1.4. It may be used for a system, subsystem, or a line that operates >2% of total plant operating time but only occasionally (<2% of the time) will the temperature of the single-phase fluid, within the piping, exceed 200oF. Thus, piping containing a single-phase flow that operates less than 2% of the time above 200oF was classified as non-susceptible to FAC.

5.1.6. Non-Water/Steam Piping Piping that transports fluids other than water or steam, such as air or oil, are not susceptible to FAC.

5.1.7. Dissolved Oxygen Concentration Lines containing water with high levels of dissolved oxygen (typically greater than 1000 ppb) are considered immune to FAC and can be excluded from further analysis [7.2]. Systems normally meeting this criterion include Service Water, Circulating Water, and Fire Protection.

5.1.8. Low or No Flow While instrumentation and/or sensing lines may operate continuously, they experience very limited fluid flow. Such piping does not experience the amount of flow required to make FAC a legitimate concern and is excluded from further analysis in favor of piping with greater FAC susceptibility.

5.1.9. Non-Piping Systems that do not contain piping (e.g. computer system) were excluded from the FAC program.

Report No. 0700.104-02, Revision 2 Page 9 of 19

CSI TECHNOLOGIES, INC. Indian Point 2 FAC System Susceptibility Evaluation (SSE) 5.1.10. Piping Removed from Service Piping that has been removed from service and capped was excluded from the FAC program. Degradation mechanisms may occur in such piping, but for Flow-Accelerated Corrosion to occur, flow is required [7.2].

Table 5.1 provides a summary of the FAC susceptibility exclusion parameters discussed in this section. Also provided is the abbreviation used for each criterion.

CSI TECHNOLOGIES, INC. Indian Point 2 FAC System Susceptibility Evaluation (SSE) 5.2. Susceptible Non-Modeled (SNM) Criteria Each line that was not excluded due to criteria listed in Table 5.1 was determined to be susceptible to FAC. An explicit determination of suitability for CHECWORKS modeling was made for these lines. For each line that is susceptible but unsuitable for modeling, the basis for that determination was recorded. Lines were determined to be non-modelable in CHECWORKS if one or more of the conditions discussed below apply.

5.2.1. Weld Type Lines with socket-welded fittings were classified as non-modelable.

Almost all small bore lines (less than or equal to 2 in diameter) are constructed using socket-welded fittings. The socket weld uses a fit-up gap of variable size. This gap can greatly impact turbulence in piping, which in turn has a significant impact on wear rate. Since the size of the fit-up gap is unknown, CHECWORKS cannot accurately predict wear for socket-welded components [7.11].

For this analysis, all small bore lines were considered socket-welded and therefore non-modelable (see 4.1.1). In addition, the extremely large linear footage of small-bore lines and the often unknown thermodynamic conditions combine to make detailed modeling of small-bore piping inefficient and sometimes inaccurate.

5.2.2. Unknown Operating Conditions In cases where operating conditions cannot be accurately obtained or calculated, accurate modeling cannot be performed. In addition to chemistry, CHECWORKS requires a value for flow, frequency of operation, and two thermodynamic values (pressure, temperature, quality, or enthalpy) to predict wear. The PEPSE Model was the primary source of flow and thermodynamic conditions [7.10]. Thermodynamic conditions were also obtained from the operating conditions found in the Piping Specification [7.8]. Operating frequency was determined by valve position in the Plant Operating Manuals [7.5], on the P&IDs [7.3], from information found in System Descriptions [7.4], and through responses to questions by Indian Point personnel [7.6].

Where operating conditions were unknown or varied, the lines were classified as SNM.

5.2.3. Conditions outside CHECWORKS Modeling Capabilities Lines that operate with conditions outside of CHECWORKS modeling capabilities were considered SNM. For example, lines with entrained moisture or vent lines containing non-condensable gases were classified as non-modelable.

Report No. 0700.104-02, Revision 2 Page 11 of 19

CSI TECHNOLOGIES, INC. Indian Point 2 FAC System Susceptibility Evaluation (SSE) 5.2.4. Visually Inspected Lines Lines that are visually inspected during outages do not require modeling.

For many plants, this criterion applies to the Turbine crossunder piping.

5.2.5. Localized FAC Susceptibility Lines that were classified as FAC susceptible only at a single location were deemed non-modelable. Examples include carbon steel nozzles and valves in a low alloy line.

5.2.6. High Steam Quality Lines that contain very high quality (but not superheated) steam were classified as SNM. Modeling such lines is of little value as CHECWORKS predictions would be trivial.

Steam quality was primarily obtained from the PEPSE model [7.10],

followed by the operating conditions found in the Pipe Class Specifications [7.8].

Table 5.2 provides a summary of the CHECWORKS model exclusion parameters discussed in this section. Also provided is the abbreviation used for each criterion.

Email from Ryan Doremus (CSI) to Ian Mew (IPEC) regarding a Line Naming Convention, dated 7/27/2009.

Ian, Im close to the point where I will have to start assigning line names for categorization purposes. Since the P&IDs seem to be very good at giving line information (size, pipe class, etc.), I want to propose a simple naming convention that consists of Unit #, System Abbreviation, a sequential number, and if needed a sequential letter that would be used if susceptibility changes within a line.

U-SSS-000-A U = Unit Number SSS = System Abbreviation 000 = Sequential Number A = Section of line that is split for susceptibility.

For example: 2-6EX-003 or 2-BFD-002-A Let me know what you think.

Thank you, Ryan D. Doremus Engineer CSI Technologies, Inc.

CSI TECHNOLOGIES, INC. Indian Point 2 FAC System Susceptibility Evaluation (SSE)

1. Do actual lines exist from the HP Turbine to the Moisture Preseparators or are the Preseparators connected directly to the turbine? If they exist, are they inspected visually or should they be included in the CHECWORKS model?

2. Is it safe to assume that all Main Steam steam trap bypass valves on 9321-F-2041 and 9321-F-2042 are normally closed despite the fact that some are shown open?

3. Does the Feedwater Heater Bypass line (A235307, G-5) operate more or less than 2% of the time?

4. Do the Boiler Feed Pump discharge lines to the Drains Collecting Tank (9321-F-2017, H-6) operate more or less than 2% of the time?

5. Does the 18 HP Feedwater Heater Bypass line (9321-F-2019, F-3) operate more or less than 2%

of the time?

6. Do the lines from the Heater Drain Pump Discharge to the HDP Water Chemistry Monitor (9321-F-2022, A2) operate more or less than 2% of the time?

7. Do the level control lines from the Heater Drain Tank to the Condenser (A235304, A-1 C-1 F-1) operate more or less than 2% of the time?

8. Do the Moisture Separator drains to the Drains Collecting Tank (9321-F-2023, H4) operate more or less than 2% of the time?

9. Do the SG Blowdown lines to the sample coolers (9321-F-2729, D-6) operate more or less than 2% of the time?

10. What is the outlet temperature of the SG Blowdown sample coolers (9321-F-2729, E-6)?

Any information on these would be helpful. Feel free to forward these questions on to system engineers or to send me operating procedures that might answer the questions. To maintain the integrity of the project schedule, we will need these answers by Wednesday, August 5.

In addition to the above, please send the Aux. Steam operating procedures (SOP 29.1.1, 29.1.2, and 29.1.3) and the following drawings:

18. Does the 18 HP Feedwater Heater Bypass line (9321-F-2019, F-3) operate more or less than 2%

of the time?

19. Do the lines from the Heater Drain Pump Discharge to the HDP Water Chemistry Monitor (9321-F-2022, A2) operate more or less than 2% of the time?

20. Do the level control lines from the Heater Drain Tank to the Condenser (A235304, A-1 C-1 F-1) operate more or less than 2% of the time?

21. Do the Moisture Separator drains to the Drains Collecting Tank (9321-F-2023, H4) operate more or less than 2% of the time?

22. Do the SG Blowdown lines to the sample coolers (9321-F-2729, D-6) operate more or less than 2% of the time?

23. What is the outlet temperature of the SG Blowdown sample coolers (9321-F-2729, E-6)?

Any information on these would be helpful. Feel free to forward these questions on to system engineers or to send me operating procedures that might answer the questions. To maintain the integrity of the project schedule, we will need these answers by Wednesday, August 5.

In addition to the above, please send the Aux. Steam operating procedures (SOP 29.1.1, 29.1.2, and 29.1.3) and the following drawings:

9321-F-2027 9321-F-2028 9321-F-2033 9321-F-2067 9321-F-2720 9321-F-2722 9321-F-2723 9321-F-2745 9321-F-7020 A205957 B237144 192491 If its possible, I would like to have these drawings and the Aux. Steam OPs by next week, even if they come separately from the questions, to give me time to analyze them. If you have any questions, please feel free to contact me.

Thank you, Ryan D. Doremus Engineer CSI Technologies, Inc.

Email from Brian Trudeau (CSI) to Ian Mew (IPEC) regarding report comments, dated 11/23/2009.

CSI Doc. No. 0700.104.C.019

Ian, This email captures our discussion today concerning your comments on the Unit 2 SSE & SNM. I understand that these two items are the extent of your comments. We will give you a call to go over these and inform you how we have incorporated them prior to sending the final version of the SSE & SNM on or before Dec 4.

1) Ian sent new data to CSIs Ryan Doremus on historical inspections and replacements that he would like incorporated. This may impact plant experience for SNM lines and susceptibility if the entire line has been replaced with FAC resistant material. CSI will assess this data, make the appropriate changes, and provide Ian with a list of impacted lines.

2) Ian requested that CSI provide comments on why SNM lines were evaluated for high consequence of failure. A reason code is given, such as plant shutdown (FT) or unable to isolate (FI), but Ian would like further comments/discussion of this reason. For example, Ian would like to know why a line would cause the plant to shutdown if it fails. For large bore SNM lines, CSI will add the note This large bore line is important to plant operation and/or may be a personnel safety issue upon failure.

CSI will apply comment 2, above to applicable lines in the Unit 3 SNM.

Thanks,
