1.0 INTRODUCTION

1.1 Background

EPRI TR-112657 [1] provides alternative examination requirements for Class 2 piping welds in lieu of the requirements currently specified in Subsection IWC for such welds in ASME Code Section XI.

This evaluation will be performed according to the EPRI methodology.

The alternative risk-informed methodology calls for the categorization of piping welds into a risk matrix. Welds are categorized based upon two essential elements:

(1) identifying and evaluating the degradation mechanisms associated with the piping system under consideration, and (2) performing a consequence of failure evaluation to determine which portions of the piping system have the highest impact on plant safety.

Once welds are categorized according to these elements, the number of inspection locations shall be at least:

+

25% of Risk Category 1, 2, and 3 welds

+

10% of Category 4 and 5 welds No volumetric or surface element examinations of Category 6 and 7 welds are required; however, all elements, regardless of risk category, are to be pressure and leak tested [1].

Only the first element of the risk-informed approach, the evaluation of degradation mechanisms for all piping systems containing Class 2 (Category C-F-1 or C-F-2) piping welds, will be considered in this calculation for Virgil C. Summer Nuclear Station (VCSNS).

1.2 Scope The following VCSNS systems, containing all of the Class 2 piping in scope, are evaluated:

Reactor Building Spray System (SP)

Residual Heat Removal System (RHR)

Safety Injection System (SI)

Chemical & Volume Control System (CS)

Main Steam System (MS)

Feedwater System (FW and EF)

Service Water System (SW)

EPRI-156-331 Page 5 of 44

The potential degradation mechanisms for these systems are evaluated in Sections 3 through 9.

1.3 Assumptions

1)

Only normal and upset conditions are evaluated. Degradation mechanisms occurring due to emergency or faulted conditions are excluded from the scope of this calculation.

2)

System and system boundary identification is defined by the current ISI Program for Class 2 (Category C-F-1 and C-F-2) welds.

3)

Negligible outleakage occurs past containment isolation valves, as they have passed the requirements for containment leak tightness.

4)

If a system and/or section of piping is filled with primary water during startup or shutdown, the water quality will remain constant throughout normal plant operation.

5)

All lines evaluated in this calculation operate under some degree of tensile stress.

6)

For simplification purposes, containment ambient temperature was assumed to be 120°F during normal operations and 100°F during shutdown cooling operations. Ambient temperature outside containment is assumed to be 700F.

7)

No outside piping surfaces in any piping evaluated are exposed to wetting from concentrated chloride bearing environments (i.e., sea water, brackish water or brine) since all piping is located indoors.

2.0 DEGRADATION MECHANISMS According to the EPRI methodology [1], all Class 2 (Category C-F-1 and C-F-2) welds in the assessed systems must be classified by failure potential. This classification is accomplished by determining those degradation mechanisms that might apply to each assessed weld. The degradation mechanisms to be assessed are given below:

TASCS Thermal Stratification, Cycling, Striping TT Thermal Transient IGSCC Intergranular Stress Corrosion Cracking TGSCC Transgranular Stress Corrosion Cracking ECSCC External Chloride Stress Corrosion Cracking PWSCC Primary Water Stress Corrosion Cracking MIC Microbiologically-Influenced Corrosion PIT Pitting CC Crevice Corrosion E-C Erosion-Cavitation FAC Flow-Accelerated Corrosion For the purposes of this evaluation, any welds susceptible to FAC can be classified as having a high failure potential; welds susceptible to all other mechanisms can be classified as having a medium failure potential. Welds in the medium category must be upgraded to the high category if the associated pipe segment is also susceptible to water hammer.

Specific guidance for determining potential degradation mechanisms based on the EPRI methodology [1] is provided in Table 2-1. In the following sections of this calculation package, the criteria outlined in Table 2-1 are used to assess the potentially active degradation mechanisms for all the Class 2 systems listed in Section 1.2 for VCSNS. Evaluations of the Richardson Number (Ri) and AT allowable for locations potentially susceptible to Thermal Fatigue (see Table 2-1) are performed in Appendix I of this calculation.

A deviation to the EPRI RI-ISI methodology has been implemented in the failure potential assessment for VCSNS. Table 3-16 of EPRI TR-1 12657 [1] limits PWSCC-susceptible materials to Alloy 600 piping material. However, recent service history at VC Summer indicates that Alloy 182 weld metal may also be potentially susceptible to this degradation mechanism. For purposes of conservatism, all Alloy 182 welds at VC Summer that meet the other PWSCC criteria are considered potentially susceptible to PWSCC.

A second deviation to the EPRI RI-ISI methodology has been implemented in the failure potential assessment for VCSNS. Table 3-16 of EPRI TR-1 12657 [1] contains criteria for assessing the Revision 0

potential for thermal stratification, cycling and striping (TASCS). Key attributes for horizontal or slightly sloped piping greater than 1" nominal pipe size (NPS) include:

> Potential exists for low flow in a pipe section connected to a component allowing mixing of hot and cold fluids, or

> Potential exists for leakage flow past a valve, including in-leakage, out-leakage and cross-leakage allowing mixing of hot and cold fluids, or

> Potential exists for convective heating in dead-ended pipe sections connected to a source of hot fluid, or

> Potential exists for two phase (steam/water) flow, or

> Potential exists for turbulent penetration into a relatively colder branch pipe connected to header piping containing hot fluid with turbulent flow, AND AT > 500F, AND Richardson Number > 4 (this value predicts the potential buoyancy of a stratified flow)

These criteria, based on meeting a high cycle fatigue endurance limit with the actual AT assumed equal to the greatest potential AT for the transient, will identify all locations where stratification is likely to occur, but allows for no assessment of severity. As such, many locations will be identified as subject to TASCS where no significant potential for thermal fatigue exists. The critical attribute missing from the existing methodology that would allow consideration of fatigue severity is a criterion that addresses the potential for fluid cycling. The impact of this additional consideration on the existing TASCS susceptibility criteria is presented below.

Turbulent penetration TASCS Turbulent penetration typically occurs in lines connected to piping containing hot flowing fluid. In the case of downward sloping lines that then turn horizontal, as-shown in Figure 2-1, significant top to-bottom cyclic ATs can develop in the horizontal sections if the horizontal section is less than about 25 pipe diameters from the reactor coolant piping. Therefore, TASCS is considered for this configuration.

For upward sloping branch lines connected to the hot fluid source that turn horizontal or in horizontal branch lines as shown in Figures 2-2 and 2-3, respectively, natural convective effects combined with effects of turbulence penetration will keep the line filled with hot water. If there is no potential for in leakage towards the hot fluid source from the outboard end of the line, this will result in a well-mixed Revision 0

Preparer/Date STC 12/21/01 Checker/Date MIT 12/21/01 File No.

EPRI-156-331 Page 8 of 44*

fluid condition where significant top-to-bottom ATs will not occur. Therefore TASCS is not considered for these configurations. Even in fairly long lines, where some heat loss from the outside of the piping will tend to occur and some fluid stratification may be present, there is no significant potential for cycling as has been observed for the in-leakage case. The effect of TASCS will not be significant under these conditions and can be neglected.

Low flow TASCS In some situations, the transient startup of a system (e.g., RHR suction piping) creates the potential for fluid stratification as flow is established. In cases where no cold fluid source exists, the hot flowing fluid will fairly rapidly displace the cold fluid in stagnant lines, while fluid mixing will occur in the piping further removed from the hot source and stratified conditions will exist only briefly as the line fills with hot fluid. As such, since the situation is transient in nature, it can be assumed that the criteria for thermal transients (TT) will govern.

Valve leakage TASCS Sometimes a very small leakage flow of hot water can occur outward past a valve into a line that is relatively colder, creating a significant temperature difference. However, since this is a generally a "steady-state" phenomenon with no potential for cyclic temperature changes, the effect of TASCS is not significant and can be neglected. In cases where some cyclic component exists, TASCS should be considered.

Convection heating TASCS Similarly, there sometimes exists the potential for heat transfer across a valve to an isolated section beyond the valve, resulting in fluid stratification due to natural convection. However, since there is no potential for cyclic temperature changes in this case, the effect of TASCS is not significant and can be neglected.

In summary, these additional considerations for determining the potential for thermal fatigue as a result of the effects of TASCS provide an allowance for the consideration of cycle severity in assessing the potential for TASCS effects, and were applied to the failure potential assessment for VCSNS. This constitutes a deviation to the requirements of EPRI TR-112657 [1], since the methodology does not presently provide any allowance for the consideration of cycle severity in assessing the potential for TASCS effects. For the reasons discussed above, this approach is considered technically justifiable. Furthermore, EPRI concurs with this position and has submitted a revision to the methodology to the USNRC for generic review and approval [2].

3.0 REACTOR BUILDING SPRAY SYSTEM 3.1 System Description [3]

The basic function of the Reactor Building Spray System (RBSS), in conjunction with the Reactor Building Cooling System, is to remove the thermal energy released to Containment by a loss-of coolant accident (LOCA) or major steam line break inside the Reactor Building at a rate sufficient to limit the resulting overpressurization to a level below the design limit, thereby maintaining Containment structural integnity. It also serves to subsequently reduce the overpressure to a low level to minimize the pressure differential that induces leakage out of Containment. The RBSS serves this function by spraying water into Containment atmosphere to absorb heat and condense steam from the steam-air atmosphere.

An alternate function of the RBSS is to reduce the concentration of airborne radioactive iodine in Containment atmosphere. This further minimizes the potential for leakage of radioactive material from Containment. Sodium hydroxide (NaOH) is added to the sprayed water for the purpose of inducing the formation of water soluble, non-volatile iodine compounds. This process effectively removed the iodine from the gaseous atmosphere and maintains it in solution in the water collected in the Reactor Building recirculation sumps.

3.2 Class Boundaries The Class 2 RBSS piping under consideration consists of RPS pump "A" and "B" suction, discharge and test lines.

3.3 Piping and Materials Table 3-1 lists the Class 2 RBSS piping. The line numbers shown in this table are also given with the weld list in Appendix A. Dimensions and material information for all piping were obtained from Reference [4]. Line descriptions were obtained from Reference [5]. Design conditions were obtained from References [6 and 7].

A summary of the evaluation of each degradation mechanism for the conditions existing in the RBSS is given below. The information on which all evaluations are based is obtained from References [3, 5, 6 and 8], unless noted otherwise. A complete list of Category C-F-1 welds in the RBSS Class 2 piping, matched with their potential degradation mechanism(s) based on the EPRI procedure, is provided in Appendix A.

The RBSS was evaluated for normal operating conditions. (NOTE: Since this system is actuated based on Reactor Building pressure, it would not initiate automatically upon a spurious SI actuation signal) 3.4.1 Thermal Fatigue (TF) 3.4.1.1 Thermal Stratification, Cycling and Striping (TASCS)

The RBSS is not susceptible to TASCS since there is no hot/cold fluid mixing.

3.4.1.2 Thermal Transient (77T)

The RBSS is not susceptible to 'IT since there are no hot/cold fluid injections.

EPRI-156-331 Page 17 of 44

3.4.2 Stress Corrosion Cracking (SCC) 3.4.2.1 Intergranular Stress Corrosion Cracking (IGSCC)

The RBSS is not susceptible to IGSCC due to the low operating temperatures and the high-purity reactor grade water present in all runs [9].

3.4.2.2 Transgranular Stress Corrosion Cracking (TGSCC)

The RBSS is not susceptible to TGSCC due to the high-purity reactor grade water present in all runs

[9].

3.4.2.3 External Chloride Stress Corrosion Cracking (ECSCC)

The RBSS is not affected by this degradation due to the fact that all insulation is in compliance with Reg. Guide 1.36 and no lines are exposed to wetting from concentrated chloride bearing environments

[10].

3.4.2.4 Primary Water Stress Corrosion Cracking (PWSCC)

The RBSS is not affected by this degradation mechanism since there are no Inconel components present.

3.4.3 Localized Corrosion 3.4.3.1 Microbiologically Influenced Corrosion (MIC)

While the RBSS cannot be excluded from potential MIC susceptibility based on strict application of the EPRI criteria, the fact that all lines are filled with high purity, reactor grade water, as well as plant service history and industry experience, indicate that MIC would not be a concern in this piping.

3.4.3.2 Pitting (PIT)

The RBSS is not susceptible to PIT due to the high quality of the high-purity reactor grade water present in all runs [9].

3.4.3.3 Crevice Corrosion (CC)

The RBSS is not susceptible to CC due to the absence of thermal sleeves in this piping.

3.4.4 Flow Sensitive (FS) 3.4.4.1 Erosion-Cavitation (E-C)

The RBSS is not susceptible to E-C due to the fact that, even if any potential cavitation sources were present, the lines would only see flow during surveillance testing, which is of insufficient duration to result in an E-C concern.

3.4.4.2 Flow Accelerated Corrosion (FAC)

The RBSS is not evaluated as part of V. C. Summer's FAC Program [11]. Therefore, this system is not considered to be FAC-susceptible.

4.0 RESIDUAL HEAT REMOVAL SYSTEM 4.1 System Description [8]

The Residual Heat Removal System (RHRS) transfers heat from the RCS to the Component Cooling Water System (CCWS) to reduce the temperature of the reactor coolant to the cold shutdown temperature at a controlled rate during the second part of normal plant cooldown and maintains this temperature until the plant is started up again.

During the first phase of cooldown, the temperature of the RCS is reduced by transferring heat from the RCS to the steam and power conversion system through the steam generators (SGs).

Parts of the RHRS also serve as parts of the Emergency Core Cooling System (ECCS) during the injection and recirculation phases of a loss of coolant accident (LOCA).

The RHRS is also used to transfer refueling water between the refueling cavity and the refueling water storage tank (RWST) at the beginning and end of refueling operations.

A summary of the evaluation of each degradation mechanism for the conditions existing in the RHIRS is given below. The information on which all evaluations are based is obtained from References [5, 6, 8 and 13], unless noted otherwise. A complete list of Category C-F-1 welds, matched with their potential degradation mechanism(s) based on the EPRI procedure, is provided in Appendix B.

The RHRS was evaluated for normal operating conditions as well as for conditions of startup/shutdown, R-R initiation and inadvertent SI actuation.

4.4.1 Thermal Fatigue (TF) 4.4.1.1 Thermal Stratification, Cycling and Striping (TASCS)

At the initiation of decay heat removal (DHR) operations, one train is put into service [15]. At this time, fluid at 350'F from the RCS is drawn into the RH pump suction, HX bypass, and return lines, which are at the shutdown containment ambient temperature of 100'F. On the condition that this flow was initiated at a low flowrate to minimize thermal shock to the system, it would result in fluid stratification in the horizontal portions of the R-R piping. However, since DHR operations are not cyclic, this situation would not result in a TASCS concern (see Section 2.0).

Portions of the RHR HX "A" and "B" discharge lines downstream of the HX bypass line tie-in are potentially susceptible to TASCS due to the high-cycle fluid mixing at different temperatures that occurs during cold shutdown conditions. At this time, a low flow of fluid at 100'F from each HX File No.

EPRI-156-331

encounters a high flow of RCS fluid at 350'F from the bypass lines, and the area where the fluids mix is considered to be a region of significant TASCS concern.

4.4.1.2 Thermal Transients (TT)

At the initiation of decay heat removal (DHR) operations, one train is put into service [15]. At this time, fluid at 350'F from the RCS is drawn into the RH suction, discharge, and HX bypass lines, which are at the shutdown containment ambient temperature of 100F. According to Reference [16],

once the RHR pump for this train is started, the operator slowly increases the flowrate until flow is indicated (approximately 1500gpm at 45% demand). Using this value as a maximum possible for flow initiation, it would still be insufficient to result in a TT to any in-scope RHRS piping.

4.4.2 Stress Corrosion Cracking (SCC) 4.4.2.1 Intergranular Stress Corrosion Cracking (IGSCC)

The RHRS is not susceptible to IGSCC due to the low normal operating temperatures and the high quality of the chemistry-controlled primary and RWST water present in all lines [9].

4.4.2.2 Transgranular Stress Corrosion Cracking (TGSCC)

The RHRS is not susceptible to TGSCC due to the high quality of the chemistry-controlled water present [9].

4.4.2.3 External Chloride Stress Corrosion Cracking (ECSCC)

The RHRS is not affected by this degradation mechanism due to the fact that all insulation is in compliance with Reg. Guide 1.36 and the suction line is not exposed to wetting from concentrated chloride bearing environments [10].

4.4.2.4 Primary Water Stress Corrosion Cracking (PWSCC)

The RHRS is not susceptible to PWSCC since there are no Inconel components present.

4.4.3 Localized Corrosion (LC) 4.4.3.1 Microbiologically Influenced Corrosion (MIC)

Some portions of the RHRS cannot be excluded from potential MIC susceptibility based on strict application of the EPRI criteria. However, the fact that all lines are filled with high purity, reactor Revision 0

EPRI-156-331 Page 22 of 44

grade water, as well as plant service history and industry experience, indicate that MIC would not be a potential mechanism in this piping.

4.4.3.2 Pitting (PIT)

The RHRS is not susceptible to PIT due to the high quality of the chemistry-controlled water present

[91.

4.4.3.3 Crevice Corrosion (CC)

The RHRS is not susceptible to CC since there are no thermal sleeves present in this piping.

4.4.4 Flow Sensitive (FS) 4.4.4.1 Erosion-Cavitation (E-C)

Throttled temperature and flow control valves in the RHR HX discharge and bypass lines are potential cavitation sources during RHR operations, but would have an insufficient fluid velocity under these conditions to result in E-C.

4.4.4.2 Flow Accelerated Corrosion (FAC)

The RRHS is not evaluated as part of V. C. Summer's FAC Program [11]. Therefore, this system is not considered to be FAC-susceptible.

5.0 SAFETY INJECTION SYSTEM 5.1 System Description [8]

The Safety Injection System (SIS), also known as the Emergency Core Cooling System (ECCS), is designed to cool the reactor core as well as to provide additional shutdown capability following initiation of the following accident conditions:

1. Pipe breaks in the RCS which cause a discharge larger than that which can be made up by the normal makeup system, up to and including the instantaneous circumferential rupture of the largest pipe in the RCS.

2. Rupture of a control rod drive mechanism causing a rod cluster control assembly ejection accident.

3. Pipe breaks in the steam system, up to and including the instantaneous circumferential rupture of the largest pipe in the steam system.

4. A steam generator tube rupture.

The ECCS components are designed such that a minimum of two accumulators, one charging pump and one residual heat removal pump together with their associated valves and piping will assure adequate core cooling in the event of a Design Basis Accident.

5.2 Class Boundaries The Class 2 SIS piping under consideration consists of piping from the RWST and containment sump to the RHR pump suction lines, RHR discharge lines to the 6" hot and cold leg safety injection lines, and lines from the charging pumps to the 2" high head safety injection lines.

5.4.1 Thermal Fatigue (TF) 5.4.1.1 Thermal Stratification, Cycling and Striping (TASCS)

The SIS is not affected by TASCS. While some flow stratification may occur in lines used for RHR discharge during decay heat removal (DHR) operations, this would not result in a TASCS concern due to the non-cyclic nature of the operation (see Section 2.0).

5.4.1.2 Thermal Transient (;T)

The SIS is not affected by TT. The RHR return flow established at the initiation of DHR operations (when 350'F RCS fluid would enter 100°F shutdown ambient return lines at 500gpm max per line

[16]) would be insufficient to result in a TT.

5.4.2 Stress Corrosion Cracking (SCC) 5.4.2.1 Intergranular Stress Corrosion Cracking (IGSCC)

6.0 CHEMICAL & VOLUME CONTROL SYSTEM 6.1 System Description [20]

The Chemical and Volume Control System (CVCS) is used to establish a programmed water level in the pressurizer to maintain proper reactor coolant inventory. The programmed level is achieved by a continuous feed and bleed operation. Bleed rate is chosen by the selection of the proper combination of letdown orifices. Feed rate is determined by throttling charging pump flow, thereby maintaining the desired pressurizer level.,

The Reactor Coolant Pump (RCP) shaft seals ensure no loss of Reactor Coolant System (RCS) inventory from the pumps. The seal design requires a continuous flow of high-pressure water. Part of the discharge of the charging pump is sent to the reactor coolant pumps as seal injection flow. Most of that flow goes directly to the RCS, but some returns to the CVCS through the CVCS seal water heat exchanger to be cooled and reused.

The metals composing the RCS are an important barrier against the release of radioactive fission products. Therefore, the integrity of these metals is very important, and is partly sustained by controlling the chemical condition of the RCS fluid. Control of the water chemistry and the activity level of the coolant is performed on a continuous basis while the CVCS is in operation.

A sudden loss of reactor coolant, caused by a pipe rupture or similar accident, removes the means to cool the reactor's core. Without cooling, the fuel clad could melt or crack, causing the release of radioactive fission products. The plant's Emergency Core Cooling System (ECCS) automatically injects thousands of gallons of water onto the core when this accident situation is sensed. The CVCS charging pumps are incorporated into the ECCS because of their high-pressure flow capability.

The RCS coolant inventory is intentionally changed during various plant evolutions. The reduced temperature, pressure, and activity of the reactor coolant in the letdown portion of the CVCS makes it a useful place from which to lower the RCS coolant inventory. The centrifugal charging pumps with their high discharge pressure provide the necessary means to add to the coolant inventory.

In summary, the CVCS functions to:

"* Control reactor coolant inventory through maintenance of programmed water level in the pressurizer

"* Supply seal water injection flow to the reactor coolant pumps

"* Control reactor coolant chemistry conditions and activity levels

"* Supply high pressure water for the ECCS

"* Fill and drain the RCS Revision 0

7.0 MAIN STEAM SYSTEM 7.1 System Description [22]

The Main Steam System (MSS) functions to convey main steam from the steam generator to the main steam isolation valves (MSIVs) and to the Emergency Feedwater pump turbine..

The Main Steam System is designed to deliver 11,220,655 lbs/hr of steam to the turbine control valves and 986,352 lbs/hr tco the reheater for a total guarantee steam flow of 12,207,007 lbs/hr. The System is designed for the same conditions as the secondary side of the steam generators. Design pressure is 1185 psig and design temperature is 600'F.

Protection against overpressure of the steam generators is provided by the Main Steam safety valves installed on the Main Steam Headers of each generator, outside of Containment. They are capable of relieving more than 110 percent guarantee steam flow at 110 percent steam generator design pressure.

Steam generator power relief valves provide the means of controlled plant cooldown by steam discharge to the atmosphere when the condenser steam dump is not available. Each valve can pass approximately 6 percent of full load steam flow. One valve is provided on the Main Steam Header of each steam generator, upstream of the Main Steam isolation valves.

7.2 Class Boundaries The Class 2 MSS piping under consideration consists of the main steam header piping between the steam generators and the MSIVs as well as the safety and power relief valve lines.

8.0 FEEDWATER SYSTEM 8.1 System Description [24 and 25]

The Feedwater System (FWS) conveys feedwater to the steam generators (SGs). The FWS consists of three pneumatic actuated feedwater isolation valves, three check valves, three main feedwater control valves, three feedwater bypass control valves, and associated piping, instrumentation, and controls.

The FWS conveys Feedwater from the non-nuclear portion of the System within the Turbine Building to a 30-inch header located within the Intermediate Building. From this header a single 1 -inch line conveys Feedwater to each steam generator.

The Emergency Feedwater System (EFS), also evaluated in this Section, provides the required feedwater flow to the SGs for cooldown when the FWS is not available. The EFS operates in conjunction with the Main Steam Dump System (MSDS), if available, or the main steam power relief valves and safety valves, to remove thermal energy from the SGs. The EFS is used, additionally, to supply feedwater to the SGs during testing, startup, shutdown, Anticipated Transients Without Scram (ATWS) event and layup operations.

The EFS is designed to automatically deliver emergency feedwater, at a minimum total flow of 380 gpm, to at least two Steam Generators pressurized to 1211 psig, within one minute after an incident which results in insufficient or termination of main feedwater flow. The EFS is also designed to automatically deliver emergency feedwater during an ATWS event. Sufficient redundancy exists to establish this minimum flow while sustaining a single active failure in the system in the short term or a single passive failure in the long term. The EFS operates until the Residual Heat Removal System (RHRS) can be placed into operation. The RHRS can be placed into service when the reactor coolant pressure and temperature are approximately 400 psig and less than 350'F. The corresponding SG shell side pressure is approximately 125 psia.

8.2 Class Boundaries The Class 2 FWS piping under consideration consists of the main feedwater lines from the Feedwater Isolation Check Valves to the steam generators, and the emergency feedwater lines from the steam generators to the 6"X4" reducers.

8.3 Piping and Materials Table 8-1 lists the Class 2 FWS piping. The line numbers shown in this table are also given with the weld list in Appendix F. Dimensions and material information for all piping were obtained from

Reference [4]. Line descriptions were obtained from Reference [5]. Design conditions were obtained from Reference [6, 26 and 27].

A summary of the evaluation of each degradation mechanism for the conditions existing in the FWS is given below. The information on which all evaluations are based is obtained from References [5, 6, 8, 24 and 25], unless noted otherwise. A complete list of Category C F-2 welds in the FWS Class 2 piping, matched with their potential degradation mechanism(s) based on the EPRI procedure, is provided in Appendix F.

The FWS was evaluated for normal operating conditions as well as conditions of startup/shutdown.

8.4.1 Thermal Fatigue (TF) 8.4.1.1 Thermal Stratification, Cycling and Striping (TASCS)

The Emergency Feedwater System is used during heatup to 3% power [30]. At 1% power, the EFW flowrate is 87gpm per SG, which is sufficiently high to preclude any TASCS concerns in the 6" lines, and the flowrate increases to 260gpm per line at 3% power [30]. At this time, the main Feedwater System is initiated at 260gpm per SG. The 130'F fluid mixing with potential 5601F SG outflow would result in a potential TASCS concern in the horizontal run between the 18"X16" reducing elbow and the steam generators.

8.4.1.2 Thermal Transient (TT)

As discussed under TASCS, the Emergency Feedwater System is used during heatup to 3% power

[30]. At 3% power, the EFW flowrate is 260gpm per SG, resulting in 95TF fluid encountering 560'F SG fluid at the nozzle. This will result in a TT at this location. At 3% power, the main Feedwater System is initiated at 260gpm per SG [30]. This flowrate is insufficient to result in a TT concern due to the mixing of feedwater fluid and SG outflow in the horizontal run between the reducing elbow and the SG nozzles. (NOTE: While welded thermal sleeves are located on both the Feedwater and Emergency Feedwater System nozzles [31], they do not preclude these regions from being TIT concerns) 8.4.2 Stress Corrosion Cracking (SCC) 8.4.2.1 lntergranular Stress Corrosion Cracking (IGSCC)

This system is not susceptible to this degradation mechanism since all piping is carbon steel.

8.4.2.2 Transgranular Stress Corrosion Cracking (TGSCC)

This system is not susceptible to this degradation mechanism since all piping is carbon steel.

8.4.2.3 External Chloride Stress Corrosion Cracking (ECSCC)

This system is not susceptible to this degradation mechanism since all piping is carbon steel.

8.4.2.4 Primary Water Stress Corrosion Cracking (PWSCC)

This system is not susceptible to this degradation mechanism since there is no Inconel present.

8.4.3 Localized Corrosion 8.4.3.1 Microbiologically Influenced Corrosion (MIC)

This system is not susceptible to MIC due to the high normal operating temperature of all lines.

8.4.3.2 Pitting (PIT)

This system is not susceptible to PIT due to the high quality of the chemistry-controlled fluid present in all lines [28].

EPRI-156-331 Page 38 of 44 8.4.3.3 Crevice Corrosion (CC)

This system is not susceptible to CC. Although thermal sleeves are welded onto the Feedwater and Emergency Feedwater System nozzles [31], the secondary water chemistry control precludes the presence of oxygen in these lines [28].

8.4.4 Flow Sensitive (FS) 8.4.4.1 Erosion-Cavitation (E-C)

This system is not susceptible to E-C due to the high operating temperatures and lack of potential cavitation sources.

8.4.4.2 Flow Accelerated Corrosion (FAC)

Some FWS components are currently evaluated in accordance with the existing plant FAC program

[11, 32, 33]. These locations will be considered potentially susceptible to FAC.

9.0 SERVICE WATER SYSTEM 9.1 System Description [29]

The Service Water System (SWS) provides water from the Service Water Cooling Pond for cooling of the emergency diesel generators, the component cooling heat exchangers, the HVAC mechanical water chiller condensers, and supply for the service water pumphouse cooling coils. During post accident conditions, loss of offsite power, or testing, the Reactor Building cooling units are cooled by the SWS. In addition, this system is the backup water source for the Emergency Feedwater and Component Cooling Water systems. The SWS consists of two independent ("A" and "B") full capacity loops with the capability of valving the third service water pump into either loop. The system is related to nuclear plant safety and is designed such that a single failure does not cause loss of cooling to more than one of the redundant loops.

9.2 Class Boundaries The Class 2 SWS piping under consideration consists of the lines between the Industrial Cooling Water Isolation valves and Containment Isolation valves (downstream of the Service Water Booster Pumps), and the check valves upstream of the Reactor Building Cooling Units.

AWN 9.3 Piping and Materials Table 9-1 lists the Class 2 SWS piping. The line numbers shown in this table are also given with the weld list in Appendix G. Dimensions and material information for all piping were obtained from Reference [4]. Line descriptions were obtained from Reference [5]. Design conditions were obtained from Reference [6 and 30].

A summary of the evaluation of each degradation mechanism for the conditions existing in the SWS is given below. The information on which all evaluations are based is obtained from References [5, 6, 8 and 29], unless noted otherwise. A complete list of Cafegory C-F-2 welds in the SWS Class 2 piping, matched with their potential degradation mechanism(s) based on the EPRI procedure, is provided in Appendix G.

The SWS was evaluated for normal operating conditions as well as conditions of inadvertent SI actuation.

9.4.1 Thermal Fatigue (TF) 9.4.1.1 Thermal Stratification, Cycling and Striping (TASCS)

The SWS is not susceptible to TASCS since there is no hot/cold fluid mixing.

9.4.1.2 Thermal Transient (TT)

The SWS is not susceptible to TT since there are no hot/cold fluid injections.

9.4.2 Stress Corrosion Cracking (SCC) 9.4.2.1 Intergranular Stress Corrosion Cracking (IGSCC)

This system is not susceptible to this degradation mechanism since all piping is carbon steel.

9.4.2.2 Transgranular Stress Corrosion Cracking (TGSCC)

This system is not susceptible to this degradation mechanism since all piping is carbon steel.

9.4.2.3 External Chloride Stress Corrosion Cracking (ECSCC)

This system is not susceptible to this degradation mechanism since all piping is carbon steel.

9.4.2.4 Primary Water Stress Corrosion Cracking (PWSCC)

This system is not susceptible to this degradation mechanism since there is no Inconel present.

9.4.3 Localized Corrosion 9.4.3.1 Microbiologically Influenced Corrosion (MIC)

The SWS is potentially susceptible to MIC. Even though a biocide has been added to the entire SW flow for purposes of MIC-prevention [29], the SWS is a low-temperature, low-flow, raw water system and hence a MIC concern.

9.4.3.2 Pitting (PIT)

The SWS is potentially susceptible due MIC, since it is a low-flow, raw water system.

9.4.3.3 Crevice Corrosion (CC)

This system is not susceptible to CC since there are no thermal sleeves present.

9.4.4 Flow Sensitive (FS) 9.4.4.1 Erosion-Cavitation (E-C)

This system is not susceptible to E-C since there are no potential cavitation sources.

9.4.4.2 Flow Accelerated Corrosion (FAC)

The SWS is not considered susceptible to FAC since no SWS locations are included in V. C.

The criteria of the EPRI Risk-Informed Procedure for thermal fatigue evaluation (as given in Table 2

1) includes the determination of certain key values: the Richardson Number (Ri) in the case of TASCS, and the allowable AT in the case of 'IT. For some operating conditions, sufficient information is available to determine the desired parameter directly, while for others, a "cut-off' (threshold) value can be established for purposes of evaluating the criteria. The methodology for determining Ri and the allowable AT is given below.

RICHARDSON NUMBER Methodology Richardson Number values were only calculated for elements potentially susceptible to TASCS-3-1 (low flow), which is sometimes combined with TASCS-3-4 (two-phase flow), as well as TASCS-3-2 (valve leakage). For TASCS-3-3 (convection heating) or TASCS-3-5 (turbulent penetration) the Richarson Number is not a meaningful value. The methodology for the evaluation of the Richardson Number is given in Reference [0-1]. The value of the Richardson number is calculated using Equation 1:

Ri = (g / p) * (Ap

• d) / u2 (1) where:

d = inner pipe diameter (ft) g = acceleration due to gravity (32.2 ft/sec)

Ap = absolute value of difference in density (lbmlft3) p = density of the stratified flowing fluid lbm/ft3) u = velocity of the fluid in the stratified portion of the pipe cross section (ft/sec)

Density values are obtained from Reference [0-2] at the hot/cold fluid temperatures. In performing the evaluations, p is taken as that of the warmer fluid, even when the colder fluid is actually flowing.

This assumption incorporates conservatism, in that it renders the evaluated piping more, rather than less, susceptible to TASCS.

As actual flowrates are often uncertain, the value of Ri was set equal to 4 (the critical value) in all evaluations, and the corresponding value of u was then determined and converted to a "threshold" flowrate. In converting between u (ft/sec) and flow rate (gpm) for comparison with actual operating conditions, the cross-sectional area used was that of the entire pipe and not merely the stratified portion. This assumption also incorporates conservatism, in that it renders the evaluated piping more, rather than less, susceptible to TASCS. This calculated flow rate was then used as a "cut-off' for evaluation purposes. If the actual flow rate was expected to be significantly lower, the piping would be considered susceptible to TASCS under the given conditions; if the actual flow rate was expected to Revision 0

\\ý_ý 00%

be significantly higher, the piping would not be considered susceptible. In cases where the actual flowrate was a known value, this conclusion could be made with even more certainty.

One further criterion was applied following the determination of the Richardson Number, and that was whether the conditions encountered were cyclic (frequently encountered, or high-frequency in nature),

as opposed to steady-state or infrequent. This criterion was used in the final d&termination regarding element TASCS susceptibility, and is discussed at some length in Section 2.0 of this calculation.

Calculated threshold flowrate values for all cases evaluated are given in Table 0-1, and are compared to actual flowrates where available. Values for temperatures, flowrates, etc. for each system are taken from the References cited in the relevant Section. Conclusions regarding potential susceptibility to the TASCS degradation mechanism are given for all cases.

AT ALLOWABLE Methodology The methodology for the evaluation of AT allowable is given in Reference [0-1], with additional information provided in Reference [0-3]. In cases where the transient flow rate is known, the value of AT allowable can be directly evaluated using the following method:

Firstly, the mean fluid temperature of the potential thermal transient is determined. Then, the heat transfer coefficient (h) is calculated using Equation 2:

h=FQO-'/DIS (2) where:

S= determined from Figure 0-1 at the mean fluid temperature [0-1]

Q = transient flow rate (gpm)

D = pipe ID (in)

Next, the value T is determined using Equation 3:

T=k/ht (3) where:

k = thermal conductivity of the material (BTU/hr-ft-0F) at the mean fluid temperature, taken from [0-4]

t = pipe thickness (ft)

Once T has been calculated, AT allowable for the transient can be determined from Figure 0-2

[Reference 0-3] for the appropriate material. If the maximum transient AT is greater than this allowable value, a Tr will occur. If not, the piping is not susceptible under the stated conditions.

Calculated AT allowable values for all cases evaluated are given in Table 0-2, and are compared to actual maximum ATs. Values for temperatures, flowrates, etc. for each system are taken from the References cited in the relevant Section. Conclusions regarding potential susceptibility to the TT degradation mechanism are given for all cases.
