CALCULATION MDQ0999970046, REV. 10, "NPSH EVALUATION OF BROWNS FERRY RHR AND CS PUMPS" This enclosure provides TVA Calculation MDQ0999970046, Rev. 10, "NPSH Evaluation of Browns Ferry RHR and CS Pumps."

The revised calculation corrects the RHR pump flow rate for the evaluation of ECCS pump NPSH for the Appendix R transient.

Figure 7.6, "RHR (Appendix R) pump curve and system curve,"

shows the corrected curves. This correction is reflected in the Appendix R results included in the calculation and used as input to TVA Calculation MDQ099920060011, Rev. 1 in . Other refinements were made to the calculation which did not impact the results.

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.

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 Head (NPSH) available for pump and system 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.

1Checked 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 for Appendix R and short term LOCA cases are determined from information taken from References 2.25, 2.32, and 2.33. Case pump flow combinations for Long term LOCA, SBO and ATWS cases are taken from Reference 2.21.

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.

4A The effective strainer hydraulic loss is taken at the point of the ECCS piping flange for the strainer.

618.625 ft (Ref. 2.32) - 588 ft (Ref. 2.23) = 30.625 ft Also, the elevation difference between the condensate storage tank (CST) water level and the torus water level had to be considered in calculating the static head.

588 ft - 536 ft (Ref. 2.32) = 52 ft The differential pressure between the reactor pressure vessel and the suppression chamber is 105 psi (Ref.

For LOCA cases, 0 psi is used. By subtracting the 105 psi, the system curve shifts down giving Equation 6.1 and the new operating point is established.

IChecked CALCULATION SHEET RHR Pump flow for LOCA-short term and Appendix R conditions are identified using the RHR pump curve (Ref. 2.2) and system head loss 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. T hese 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 system head that must be overcome is calculated by revising the results of Reference 2.25 for the case being examined using the following equation:

H=Hf +Hs-Pj+PR (Eq. 6.2)

H = Total Head (ft)

Hr= Friction Loss (fi)

Hs = Total Static Head (ft)

Pj = Jet Pump Pressure (ft) (removed as the recirculation loop discharge valve remains open during the Appendix R event - Ref. 2.36)

PR = Reactor Pressure (Ref. 2.24)

For Appendix R, the total static head (HR) is determined based on a reactor water level at the bottom of the Main Steam Line nozzle, normal torus water level, reactor pressure of 100 psig (Ref. 2.24), and no losses through the jet pumps since the recirculation loop discharge valve remains open during the Appendix R event (Ref. 2.36). The reactor pressure is controlled 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 (H,) = (632.04'-536')-(632.04'-628.17') = 92.17 ft 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. 2.24) reactor pressure that has to be maintained by the operator to ensure MSRVs continue operation.

Jet Pump Pressure is neglected since the recirculation loop discharge valve remains open during Appendix R event (Ref. 2.36), which eliminates jet pressure.

Jet pressure = 123 psi at 30,000 gpm, (Ref. 2.25) adjusted to percentage of flow in the system.

To determine the required pressure in the reactor pressure vessel to allow Appendix R cases to run at 7200gpm or less, a new system curve is developed by adding a head loss to the existing system curve, which shifts the operating point below 7200 gpm (See Table 6.7).

RHR discharge elevation at connection to Recirculation loop = 577.17 ft Water level in the torus = 536 ft Total Static Head (H-I)= (577.17 ft - 536 ft) = 41.17 ft 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 is 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:

CALCULATION SHEET 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 3=h.+h 3-hf-h, (Eq. 6.3) where:

h. = Atmospheric head = Suppression Pool airspace pressure converted to feet of water (ft).

h, = Static pressure h ead = Elevation difference b etween t he centerline o f t he pump i nlet and t he suppression pool water level (ft).

hf= Total friction head loss (ft).

hv = 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 7.0). 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 7.0).

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 60OF 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. Reference 2.15 provides strainer head loss for two different time periods. For short term (ess than 10 minutes), head losses are provided for three flows.

For long term (greater than 10 minutes), head loss is provided for one flow rate. Flows obtained from Reference 2.15 were converted to flow at standard conditions using Equation 6.4. Values of head loss at corresponding strainer flow rates, taken from Reference 2.15, are converted to head loss at standard conditions. A curve was developed and input into MultiFlow representing the head loss at the strainer addressing the variation in strainer head loss for the two time periods. Based on a review of Reference 2.15, the strainer head loss varies linearly with flow through strainer.

CALCULATION SHEET In order to assist analysis convergence in the ATWS, Appendix R and SBO cases, "dummy" check valves with a minimum equivalent length to model strainer loss were installed in the piping links 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.

Point A is the strainer piping flange.

Point A elevation = 525.333 + 2.283 = 527.616' and static head of Pt. A = 536.062 - 527.616 = 8.446' These pressures are valid for cases where water is routed directly to the suppression pool (Appendix R and ATWS). These values were established at the strainer flange points (nodes 1,5, 23, and 27) for the specified temperatures. The densities as a function of temperature in the following equations are taken from STMFUNC (Ref. 2.22).

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)

CD vent h = 25 1/2" COrKto EL 549.92 (Ref. 2.29) aIter Level EL 540.92 (Ref. 2.34)

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 A 2 = 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.

The volume of the concrete is found by using the equations in Reference 2.27:

SuLject Pump/Flow Combination Cases for MULTIFLOW EPU Revision to NPSH Calculation Don.

The attached Is a lsting of the cases we have agreed upon. The number of cases is very similar to that of the existing calculation. It doesn't take long to modify the input and run each case - the largest effect is formatting and presenting the results. Iam 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.
