NPSH Evaluation of Browns Ferry RHR and CS Pumps Prepared _ Date IChecked Date CALCULATION SHEET 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.2. REFERENCES

NPSH Evaluation of Browns Ferry RHR and CS Pumps Prepared Date.___I Checked -Date-CALCULATION SHEET 3 DESIGN INPUT DATA Input data required is derived from references shown above. The pump fluid temperatures are taken from TVA correspondence (Ref. 2.21 and Ref. 2.30). Case pump flow combinations are determined from information taken from References 2.25, 2.32, and 2.33.4 ASSUMPTIONS 4.1 No pressure drop is assumed across the strainers for ATWS, SBO, and Appendix R events.These events do not result in debris entering the suppression pool and the strainers are large enough to have negligible pressure drop when clean. Check valves with minimal equivalent length are included to aid with convergence.

4.2 For bends with no angle and/or curvature information denoted on drawings, 90" short radius elbows are conservatively assumed.4.3 HPCI and RCIC systems are assumed to not operate in a mode drawing suction from the torus ring header for all analyzed cases.4.4 The effective strainer hydraulic loss is taken at the point of the ECCS piping flange for the strainer.5 SPECIAL REQUIREMENTS/LIMITING CONDITIONS None Document:

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.TABLE 6.1 : CS Pump Curve Flow Head(ft)0 861 500 848 1000 825 1500 792 2000 749 2500 694 3000 626 3500 538 4070 409 4570 261 Data from the Pre-Operation report is used to develop a system curve (Ref. 2.32). 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 5 X 2+30.625 ft (Eq. 6.1)

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 (gp-m)0 1000 2000 3000 4000 5000 6000 7000 8000 9000 10000 10950 11950 12950 Head (0 92 96 107 125 150 183 223 270 324 386 455 527 610 700 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 223 0 F (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.TABLE 6.7: Dual Pumps Flow Head (gpm) (It)0 825 4000 810 6000 800 8000 787 10000 775 12000 755 14000 716 16000 675 18000 625 20000 575 22000 525 24000 475 As in the Appendix R case, the head loss curve is developed by revising the results of Reference 2.25 for the case being examined using the following equation: 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)Friction Loss = 526 ft (Ref. 2.25), adjusted based on the ratio of flow in the system.500 \oo Hf at 5000gpm= 50000) *526= 33ft Hf at 10000gpm =(2' J *526= 132ft H(at 15000gpm =2" *2 Hatl".O(tmm tl ) *526=296ft Hf at 20000gpm = 2 *526 526ft 20000)

@ 200WF Two RHR Pump (B/D) -6500 gpm, A/C -0 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- (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.

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.

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.Pool Level S 39'4 (Ref. 2.6)A-a -525- 4" (Ref. 2A)Ring Header Figure 6.1 Angle = 400 (Ref. 2.7 a, b and c)h is the vertical distance from point A to the Ring Header centerline.

NPSH Evaluation of Browns Ferry RHR and CS Pumps Prepared Date I Checked _ Date CALCULATION SHEET 8 RESULTS AND CONCLUSIONS Summary values of pump NPSH available are shown in Tables 6, 10 and 13 for Units 1, 2 and 3 respectively.

These values are based on zero credit for containment overpressure as indicated in column five of tables 6, 10, and 13.Flows used in Multiflow cases are conservatively higher than flows identified in this calculation.

All steps taken to calculate NPSHa are shown in Tables 7.1 through 7.24 for Unit 1, Tables 11.1 through 11.24 for Unit 2, and Tables 14.1 through 14.24 for Unit 3. The pump pressures are obtained from Multiflow output files. The equations used in these tables are shown in Table 8.Tables 9, 12 and 15 list the strainer pressure drop and flow rates for Units 1, 2 and 3 respectively.

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 4 the 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.Tom Newton LOCA Cae l MULIIFLI.W Revisio NPSH CiamLdoc Ij H o' C A W cvýt V::ýG- fc 7 o0 o0 Pumn/Flow Combinations for MULTIFLOW Revision to NPSH Calculation Note I -All cases to be run at 0 containment overpressure conditions Note 2 -LOCA strainer resistance to be developed as a function of strainer flow and input as a resistance element in MULTIFLOW model, special event strainer resistance taken as zero.Note 3 -All cases at EPU conditions only Note 4 -Cases at which NPSH. = NPSH, will require iteration on pool temperature to determine final pool temperature LOCA Pump/Flow Combinations Suppression Pool Temperature CS Pumps A/B/CAD- 3125 gpm each Temperature
