For the Appendix R condition a single pump curve is developed by utilizing points from the pump curve (Ref. 2.2), Table 6.4 shows points taken from Ref. 2.2 pump curve data. These points are used to develop the pump curve shown in Figure 7.6. | |||

This curve is also based on flow through the jet pumps. | |||
The results of Ref. 2.25 will be modified to develop the system head loss curve for the Appendix R case. | |||
The total head is developed by revising the results of Calculation Reference 2.25 for the case being examined using the following equation: | |||
H-=H +H,-P, H = Total Head Hf-= Friction Loss H, = Total Static Head Pi = Jet Pump Pressure (removed as the recirculation loop discharge gate valve remains open during the Appendix R event - Ref. 2.36) | |||

Adjusting for the elevation difference between the bottom of the MSL and the PI tap (241.82 ft - (632.04 ft - 628.17 ft) gives an additional 237.95 ft of head.

008 In this revision the existing EZ-flow model contained In Calculation MDQO-999-970046 was converted to Multi-Flow 1.21 using the hardcopy files contained In the calculation. The Multiflow model was verified against current plant layout and configurations and case runs were made using the same pump configurations and flows as Rev. 007 with temperatures updated for Extended Power Uprate (EPU) conditions.
This revision also Includes evaluation of ECCS pump NPSH for the special events of Anticipated Transient Without Scram (ATWS). Appendix R, and Station Blackout (SBO) at Extended Power Uprate (EPU) conditions.
The model results were used to perform NPSH calculations for the RHR and CS pumps for various pump combinations and rated flow demands on the suction piping at various suppression pool temperatures.
FSAR sections 6.4, 6.5 and 6.15 and the Technical Specifications have been reviewed for changes associated with this change. This calculation revision reflects parameters/values associated with the Implementation of Extended Power Uprate (EPU). This condition will require license amendments that will revise various FSAR and Technical Specifications. Incorporation of EPU conditions for ECCS analysis into the FSAR and Technical Spec~ff ca*ons wJbe accomplished as a part of the EPU license and amendments following NRC approval._

- 1. PURPOSE The purpose of this revision is to revise the existing Emergency Core Cooling System (ECCS) suction piping hydraulic analysis to be based on the current accepted TVA method (Ref. 2.5) at Extended Power Uprate (EPU) conditions. Results of that analysis are then used to compute the Net Positive Suction H cad (NPSH) available for pump and s ystem flows. This revision also includes evaluation of ECCS pump NPSH for the special events of Anticipated Transient Without Scram (ATWS), Appendix R, and Station Blackout (SBO) at EPU conditions. NPSH available is determined for various ECCS pump combinations and rated flow demands on the suction piping at various suppression pool temperatures. In this revision the appropriate uncontrolled flows for the short term LOCA and Appendix R will be established. The impact of drywell hold-up volume on suppression pool level will be addressed in this revision.

CALCULATION SHEET The results presented are based on the conditions specified for each of the analyzed scenario. These conditions must be met for the results of the applicable scenarios to be valid.
Utilizing Figure 7.7, Core Spray pump flow is established by finding the operating point between the pump curve and the system curve. The system curve is determined by modifying the Pre-operational report data (Ref. 2.32). The Pre-operational report data accounts for the difference of elevation between the torus and the condensate storage tank.
Core Spray pump curve head and flow values are presented in Table 6.1.

Flow for the CS pump is taken and the corresponding head is taken from the pump curve (Ref. 2.2). The following equation is used to create a curve fit, Y =AX2 + Static head (ft)
Where:
Y = Head (ft)
A = Constant X = Flow (gpm) 380 ft (Ref. 2.2) = A(4213gpm) 2 (Ref. 2.32) + 30.625 ft A= 1.971906 x 10.5 Static head is equal to the difference between the water level elevation in the condensate storage tank and the vessel inlet nozzle.
618.625 ft (Ref. 2.32) - 588 ft (Ref. 2.23) = 30.625 ft Utilizing the calculated constant, the system curve is developed using the following equation:
Y = 1.97190 x I 0 5X2+30.625 ft (Eq. 6.1)

CALCULATION SHEET The established data is modified to include the elevation difference between the condensate storage tank (CST) water level and the torus water level.
588 ft - 536.0625 ft (Ref. 2.32) = 51.9 ft and adding this addition of elevation to Equation 6.1 develops the desirable system curve.

RHR Pump flow for LOCA-ST and Appendix R conditions are identified using the RHR pump curve (Ref. 2.2) and developed system head curves.
For the Appendix R condition a single pump curve is developed by utilizing points from the pump curve (Ref. 2.2), Table 6.4 shows points taken from Ref. 2.2 pump curve data. These points are used to develop the pump curve shown in Figure 7.6.

This curve is also based on flow through the jet pumps.
The results of Ref. 2.25 will be modified to develop the system head loss curve for the Appendix R case.
The total head is developed by revising the results of Calculation Reference 2.25 for the case being examined using the following equation:
H-=H +H,-P, H = Total Head Hf-= Friction Loss H, = Total Static Head Pi = Jet Pump Pressure (removed as the recirculation loop discharge gate valve remains open during the Appendix R event - Ref. 2.36)
The friction loss of 460 ft, determined in Ref. 2.25, is adjusted as shown below, for the multiple flows in the system used to develop the system head loss curve.

H, t 1800pm= (10800 2 *"460=460ft For Appendix R, the total static head (HI) is determined based on a reactor water level at the bottom of the Main Steam Line nozzle, normal torus water level, reactor pressure equal to or greater than 100 psig (Ref. 2.34), and no losses through -thejet pumps since the recirculation loop discharge gate valve remains open during the Appendix R event (Ref. 2.36). The reactor pressure is controlled by the operator based on reading PI-3-79 (Ref. 2.36). The reactor pressure of 100 psig is corrected to the bottom of the MSL from the location of the tap.
Total Static Head (KI-)= Water level at the bottom of Main Steam Line (MSL) reactor vessel nozzle (Ref. 2.34) -Water level in the torus (Ref. 2.25).
Water level at Main Steam Line (MSL) = 632.04 ft Water level in the torus = 536 ft PI-3-79 elevation = 628.17 ft (Ref. 2.35)
Pressure Indicator elevation is subtracted to account for the 100 psi (Ref. 2.34) reactor pressure that has to be maintained by the operator to ensure MSRV's continues operation.
Total Static Head (H-)= (632.04'-536')-(632.04-628.17) = 92.17 ft Jet Pump Pressure is neglected since the recirculation loop discharge gate valve remains open during Appendix R event (Ref. 2.36), which eliminates jet pressure.
Jet pressure = 123 psi, (Ref. 2.25) adjusted to percentage of flow in the system.

CALCULATION SHEET A plot of system head at the corresponding flows is developed using a third degree polynomial curve fit. The system head loss curve is presented with the pump curve in Fig. 7.6. Table 6.6 depicts the system head at various flows.
TABLE 6.6:
Pump system curve Flow Head (gp-m) (0 0 92 1000 96 2000 107 3000 125 4000 150 5000 183 6000 223 7000 270 8000 324 9000 386 10000 455 10950 527 11950 610 12950 700 Based on Figure 7.6, the system operating point is at 10,950 gpm with a corresponding head of 527 ft.
The reactor pressure is required to be 100 psig or greater based on Ref. 2.34. The system operating point requires adjustment for the reactor vessel pressure. The Appendix R condition is based on a temperature of 2230F (Ref. 2.30). Utilizing the conversion factor at that temperature (Ref. 2.13), 100 psig is converted to 241.82 feet. Adjusting for the elevation difference between the bottom of the MSL and the PI tap (241.82 ft - (632.04 ft - 628.17 ft) gives an additional 237.95 ft of head. Adding 237.95 ft to the static head of 529 feet, a new system head is established. This head is used to find the flow for the RHR pumps for the Appendix R case.
From Figure 7.7, the corresponding flow for a head of 767 ft is approximately 5,250 gpm. This flow is less than the flow used in the NPSH model (7,200 gpm) and the NPSH model therefore provides conservative results.
For the LOCA-short term scenarios, a dual pump curve is obtained by utilizing the data from the single pump curve and doubling the flow at constant head values (Ref. 2.2), Table 6.7 shows dual pump curve data.

H=Hf +HS-Pj H = Total Head Hf= Friction Loss H. = Total Static Head Pi = Jet Pump Pressure (removed as this case considers a broken recirculation loop)

CALCULATION SHEET Total Static Head (K,) = RHR discharge elevation at connection to Recirculation loop (Ref. 2.37) - Water level in the torus (Ref. 2.25)
RHR discharge elevation at connection to Recirculation loop = 577.17 ft Water level in the torus = 536 ft Total Static Head (H.) = (577.17 ft - 536 ft) = 41.17 ft Since the Jet Pump pressure loss needs to be subtracted out since it was included in Reference 2.25 analyses. In the analyses in this calculation, the recirculation loop discharge broken, the pressure loss for the jet pump must be removed from the system head loss.
From Reference 2.25, the Jet Pump pressure loss at 30,000 gpm = 123 psi.
As system head will be developed for multiple flows, the losses through the jet pump need to be determined at those flow rates. The loss at 30,000 gpm is adjusted based on flow consistent with the methodology in Ref. 2.25:

Per American Hydraulic Institute standards (Ref. 2.20), the required Net Positive Suction Head (NPSHr) of a pump is the NPSH that will cause the total head to be reduced by 3%, due to flow blockage from cavitation vapor in the impeller vanes (Ref. 2.20).
The NPSHa is the actual fluid energy delivered to the pump impeller through the piping configuration and is calculated by the following equation (Ref. 2.3).
NPSH. = ha + h, - hf- h* (Eq. 6.3) where:
ha = Atmospheric head = Suppression Pool airspace pressure converted to feet of water (ft).
h, = Static pressure head = Elevation difference between the centerline of the pump inlet and the suppression pool water level (ft).
hf= Total friction head loss (ft).
hVP = Vapor pressure of water at system temperature (ft).
The Browns Ferry Plant ECCS configuration includes an ECCS ring header circumscribing the suppression chamber with connecting piping to four inlet penetrations through the torus wall into the suppression pool. Inside the suppression pool, each connecting line is fitted with a flanged surface for mating to the ECCS strainer flanges. The ECCS ring header supplies the suction piping of the RHR, CS, High Pressure Core Injection (HPCI) and Reactor Core Isolation Cooling (RCIC) systems.
Since the ECCS ring header and the connecting piping to the ECCS strainers is common to the suction of all of the ECCS pumps, the flow and pressure distribution for the ring header and strainers is different for varying system demands. Therefore, to determine individual ECCS pump suction pressures for various plant states, a model of the suction piping configuration was created from TVA drawings (Ref. 2.4 and 2.6) for analysis with the Multiflow computer program (Ref. 2.5). A simplified layout of the Multiflow model for the ECCS ring header and suction piping to the RHR and CS pumps is shown in Figure 7.1 (See Section 8.0). All model link input dimensions and components were taken from TVA drawings (Ref. 2.4 and 2.6) which contained systems configuration and dimensions. Nodal diagrams for Units 1, 2 and 3 ECCS hydraulic models are shown in Figures 7.2, 7.3 and 7.4, respectively (See Section 8.0).
For piping links in the model, piping lengths included the total piping isometric dimension. When drawings did not specify whether a piping elbow was short or long radius, the conservative case, e.g.
short radius was chosen. The types of valves used in the models were taken from Reference 2.6. For all form losses (elbows, valves, etc.), the Multiflow default values of equivalent length, resistance, etc. were selected. The piping roughness value of 0.00015 ft was selected, which is acceptable for a condensate quality system and would not be expected to change with the system age.

CALCULATION SHEET In the MultiFlow, model the flow is represented in sgpm, requiring the conversion from gpm. The conversion is shown below.
Flow (gpm)
- Specific Volume of Water at standard Temp. and Pressure = Flow(sgpm) (Eq 6.4)
Specific Volume of Water at desired Temp. and Pressure The standard temperature and pressure used in Multiflow is 60'F at 14.7 psia. All flows are converted to sgpm at the corresponding temperature for all cases. All sgpm conversions are shown in Tables 4 and 5.
For the LOCA cases, in the MultiFlow model a pump component is used to model the strainer pressure drop as a function of the flow rate. Flows obtained from Reference 2.15 were converted to flow at standard conditions using Equation 6A. Values of head loss at corresponding strainer flow rates taken from Reference 2.15 are converted to head loss at standard conditions. A plot of head loss at standard conditions was developed. A third order polynomial equation of head loss at standard conditions was developed in order to obtain head loss values between data points (See Fig. 7.5).
Table 6.13 depicts the head loss used to model the strainers as a function of flow. The values listed in Table 6.13 are linearly interpolated in Multiflow to obtain the system head loss.

CALCULATION SHEET from the strainer flanges to the ECCS ring header tees. For these special cases, the strainer pressure drop is assumed to be zero since there is no debris in the strainer.
Pump static suction head is equal to the available water level above pump suction centerline. In the Multiflow model, the static head at the strainer flange node is needed for calculation purposes. It is necessary to establish this value in psig in the Multiflow model at the strainer flanges. From TVA drawings (Ref. 2.6), the low water level of the suppression pool is 536' 1 3/4" with Ap and 536' 3/4" with zero delta P, which will be considered here.

CALCULATION SHEET For cases where the water is routed through the drywell (All LOCA and SBO cases), holdup in the drywell must be taken into account. This will reduce the suppression pool level that can be considered in NPSH calculations. The volume of water holdup in the drywell is calculated as follows. (See Figure 6.2)
Figure 6.2 From Figure 6.2 (Ref. 2.28) the volume of the standing water in the drywell beneath the level of the vent is calculated by finding the volume of two spherical segments, the concrete portion and the concrete and water portion, and subtracting to obtain the volume of the water:
To find the radii of the water and concrete surfaces, basic geometry is used:
C = 33.5' -9' = 24.5 ft D = 33.5' - 9' - 2.125' (Ref. 2.28) = 22.375 ft A2 = 33.52-24.52= 522.0 ft A = 22.85 ft B2 =33.52 _ 22.3752 = 621.61 ft B=24.93 ft Where A, B, C, and D are segments defined on Figure 6.2.

To obtain the NPSH available, it was necessary to subtract fluid vapor pressure hp (at the analyzed suppression pool temperature) and take into account the suppression pool absolute pressure. Utilizing Equation 6.1, the available NPSH is determined. See Tables 7.1 through 7.24 for calculations of NPSHa for Unit 1. See Tables 11.1 through 11.24 for calculations of NPSHa for Unit 2. See Tables 14.1 through 14.24 for calculations of NPSHa for Unit 3.

This meant adding I psi to the short term results for RM and subtracting I psi from the long lenn rmsuts forCS in Tables I and 2 since the calculation already considered 2 psi in its original deweibn-istic resulb. Revision 3 modifird the calculation results per the NRC SER of approvd ovceTessure for NPSIL The conversion factor for I psi used in performng this calculation was 2-31 VOL The orign resilts of the calclto utilized the conversion factor corresponding to the suppression pool t emrature as listed in Table 3 of the calcuation.

Subject Pump/Flow Combination Cases for MULTIFLOW EPU Revision to NPSH Calculation Don.
The attached Is a listing of the cases we have agreed upon. The number of cases Is very similar to that of the existing calculation. It doesn' take long to modify the input and run each case 4the largest effect is formatting and presenting the results. I am leaving the office for the day, but will be here most of the day tomorrow. I will call you when I get in so that we can discuss any questions on the cases listed.
