CALCULATION SHEET gggg PREPARED BY: PD}f CALC.# M462 CHECKED BY: h REV. E3 DATE 25-NOV-97 SHEET 6 OF 103 1.0 Statement of Problem This calculation provides an analysis of NPSH conditions for the RHR and Core Spray Pumps during performance test conditions and determines the margin for NPSH available following the Design Basis Loss of Coolant Accident (DBA LOCA). Proper and reliable , performance of Emergency Core Cooling System (ECCS) pumps requires adequate net i positive suction head (NPSH) which is defined as the absolute pressure at the pump impeller datum less the vapor pressure of the fluid being pumped. If the available NPSH is less than the NPSH required by the pump, cavitation will occur within the pump. Cavitation reduces the pump performance and may cause mechanical damage. It is necessary to calculate the head losses in the suction lines for the RHR and Core Spray Pumps under normal testing and accident conditions The suction head losses will be used to evaluate pump NPSH at the normal testing and DBA LOCA conditions to determine the minimum margin that will be available to accommodate potential degradation of the suction strainers from LOCA-generated debris. A fixed amount of margin is subtracted from the total available and is used as the basis for the maximum allowable strainer head loss at normal conditions to be applied during pump In-Service Testing (IST). l It is necessary to perform a time dependent analysis of NPSH conditions following the DBA LOCA using the predicted suppression pool temperature profiles and postulated values for containment leakage to determine the minimum NPSH margin that will be l available. The suppression pool profiles are based on the design basis recirculation line break DBA LOCA with 65 F and 75 F ultimate heat sinks Results from the analysis are presented in new FSAR figures showing the minimum NPSil margin for the low pressure ECCS pumps following a DBA LOCA. 2.0 Summary of Results and Recommendations i ! Table 4 provides the suction pressure drop that is calculated for each RHR and Core i I Spray Pump operating at the normal IST performance test conditions and at accident conditions The test condition value represents the pressure drop at the pump suction I l between the idle pump no-flow condition and with the normal pump test flow rate 1 i Tables 5,6, and 7 provide calculations of the available NPSH and margin for suppression ; I pool temperatures of 130 F,166 F. and 185 F. These are the suppression pool temperatures at the stan and at the peak for the 65 F and 75 F heat sink design cases ! [Refs 10 & 37]. Table 8 gives the available NPSH at the point of minimum NPSH margin l during the Suppression Pool cooldown when containment pressure drops back to o psig. l With the suction conditions degraded due to LOCA-generated debris, a positive NPSH margin must be maintained at the peak pool temperature based on the corresponding
l CALCULATION SHEET g gg PREPARED BY: PDit CALC.# M-662 CHECKED BY: M REV. E3 DATE 25-NOV-97 l SHEET 6 OF 1o3 wetwell pressure shown on Figures 4 and 6 (described below). Evaluation of the ECCS , pump NPSH conditions with LOCA-generated debris is included in Ca'.ulation M-734 l [Ref. 39]. Conditions associated with the DBA LOCA are used because this event produces the highest peak in suppression pool temperature. Table 8 provides the available NPSH and margin for the point of minimum NPSH margin l following a DBA LOCA based on the results shown in Figures 5 and 7 (described below). l The 128 F data corresponds to the 5% per day leakage case at the peint of minimum l margin when the containment pressure has decreased to atmospheric pressure for the 65 F ! heat sink design case. The 124 F data corresponds to the 1% per day leakage case and the 132 F data corresponds to the 5% per day leakage case at the point of minimum margin when the containment pressure has decreased to atmospheric pressure for the 75 F heat sink design case. ! Figures 4 and 6 provide graphical presentations of the calculated values for " primary l containment pressure" and the " containment pressure necessary to meet NPSH required" for both the RHR and Core Spray pumps after a DBA LOCA with 65 F and 75 F heat ! ' sinks. Containment pressure is evaluated for a containment leakage rate equal to the l Technical Specification (TS) limit (1%/ day) and 5 times the TS limit (5%/ day). Figures 5 and 7 provide graphical presentations of NPSH margin as a function of time i after a DB A LOCA with 65 F and 75 F heat sinks. The margin curves shown on this ! figure are the difference between the primary containment pressure and the containment l pressure required to meet the NPSHa for the pump. The Core Spray pumps are predicted j to have smaller NPSH margin throughout the accident response. For the 65 F heat sink l i case, the point ofleast margin for the Core Spray pump occurs during the suppression ! pool cooldown, approximately 39 hours afler the accident at which time Core Spray pump l l margin is approximately 10.6 feet. The minimum RHR pump margin occurs at the same l time and is approximately 11.7 feet. For the 75 F heat sink case, the point ofleast margin l for the Core Spray pump occurs during the suppression pool cooldown, approximately 72 j hours afler the accident at which time Core Spray pump margin is approximately 10 0 feet. 1 The minimum RHR pump margin occurs at the same time and is approximately iI 2 feet From these total NPSH margin values 2 feet are deducted and the remaining margin is the minimum available for accornmodating LOCA-generated debris on the suction strainers. Based on the information pre:sented, substantial NPSH margin will be available to assure reliable operation of the RHR and Core Spray pumps Available NPSH will exceed l required NPSH over the entire range of suppression pool temperatures that are predicted j following the DBA LOCA. To complete an analysis for the adequacy of NPSH available i to the RHR and Core Spray pumps, a debris head loss analysis must be performed for l comparison to the margin for NPSH available presented in this calculation The debris I analysis and comparison to the NPSH margin is included in Calculation M-734 [Ref 39). l

- I 3.0 Calculation of Total Suction Losses and NPSH Available 3.A Method of Solution i This calculation determines the suction line losses for the RHR and Core Spray Pump. )
These losses are used to predict the suction pressure drop that will occur with a clean ! strainer. The suction line head loss is calculated at the conditions for temperature and pump flow rate for the pump performance In-Sersice Test (IST). The calculation for : suction head loss is repeated at the predicted accident conditions for wetwell temperature, l pressure, and pump flow rate. This calculation predicts the NPSH available at the ECCS pump suctions under accident conditions and the resulting margin between NPSH , Available and NPSH Required. A number ofvariables determine the margin for NPSil available to the pumps. Principally
' they are:
Suppression pool water level, temperature, and density. Wetwell pressure. Vapor Pressure of the suppression pool water. Pump suction line head loss which is principally a function of geometry and flowrate (which includes the clean suction strainer head loss). 3 The suction pressure drop as would be read on a pressure gage mounted at the pump suction is also calculated. The pressure drop is the difTerence in the pressure read with the ! pump idle (0 gpm) and with the pump at the test flow rate. This measurement method cancels out the effect of gage height versus the datum such that only the delta-P is imponant. There is a maximum amount of strainer fouling that can be tolerated such that there will be l adequate NPSH to the ECCS pumps under containment accident conditions. This calculation determines the minimum margin for NPSH available to the ECCS pumps following the bounding DB A LOCA. A fixed amount of the total available margin is used to calculate the maximum pressure drop that may be allowed during routine pump performance testing. The allowable pressure drop for the test conditions is based on the calculated suction line losses at the accident conditions for wetwell temperature, pressure, and pump flow rate. The pressure drop at the test conditions (Poror-suuc - Poror.atwiso ) provides a measure of the dynamic pressure drop caused by resistances and restrictions in the suction line plus l the conversion of static head to velocity head as follows. l dP = Parar-snue - Paror.uivre; = Suction Line Pressure Drop + Velocity Head 1

E3 DATE 2540V-97 SHEET 8 OF 103 The allowable suction dP is a fixed amount of NPSH margin allocated for surveillance testing purposes and must be of suflicient magnitude so that it is within a reasonable measurement range considering testing accuracy and repeatability. 3.B Input Data and Assumptions The physical configurations of the suction lines to the RHR and Core Spray Pumps are taken from the drawings listed in the Reference section. The head losses due to pipe fittings are in accordance with [Ref. 7]. Pipe friction values are based on the Moody diagram [Ref. 7]. The pipe roughness value was selected for steel pipe with light rust per [Ref. 8]. The strainer characteristics are in accordance with [Ref.14]. The design basis accident conditions inside containment are in accordance with [Ref 10,37]. The 5600 gpm RHR Pump flow rate is the mnout flow for single pump operation. This single pump value of flow bounds the per-pump flow for the two-pump case used in accident analyses [Ref.11,12]. The 4400 gpm Core Spray Pump flow rate is the runout flow rate assumed in the accident analysis (4100 gpm) plus a minimum flow recirculation flow rate of 300 gpm [Ref. I1,12]. The following assumptions apply:
- 1. The RHR and Core Spray Pump accident flow rates of 5600 gpm and 4400 gpm, respectively, correspond to the flow at zero reactor pressure.
- 2. The RHR and Core Spray Pump performance test Oow rates of 4800 gpm and 3300 gpm, respectively, correspond to the IST test conditions with 80 F torus water

, The maximum allowable pump suction pressure drop as measured at the IST testing conditions is based on the total suction head losses plus the additional fixed head loss of 2 feet at the accident conditions for wetwell '.empetature, pressure, and pump flow rate. The total suction head loss (hst)is calculated at both the IST conditions for temperature and pump Dow rate and for the accident conditions. The fixed head loss of 2 feet at the accident conditions is used to calculate a + maximum dP for the test conditions that will ensure that NPSH s will meet or exceed the available margin for LOCA debris at the accident conditions using the following relationship:

This mass of nitrogen is based on a Drywell volume of 132,000 ft' which is a conservatively low value for determining the minimum credible initial mass. The DB A-LOCA involves a breakdown of the reactor vessel pressure boundary with subsequent flooding of only the core volume within the reactor shroud.

E3 DATE 25-NOV-97 SHEET _ ZI OF (03 Section 4.0 Modated FSAR NPSH Analyses and Finures i Section 4.A Method of Solution i This section of the calculation prepares updated NPSH analysis for the FSAR. The original , analysis was submitted to the AEC during the Pilgrim licensing review via Amendments 9 and 24 ) to the SAR. This analysis was incorporated into the FSAR as Figures 14.5-9,14.5-10, and l 14.5-13 and Section 14.5.3.1.3. The revised analysis in this calculation will be incorporated into I. the UFSAR. The same approach used in the original FSAR analysis is used. Considering a known suppression pool temperature profile, the coincident containment pressure is calculated using simple thermal i equilibrium assumptions. The " Containment Pressure Required" to provide the necessary NPSH is calculated and plotted with the coincident containment pressure. The difference between the containment pressure at any point in time and the containment pressure required represents NPSH margin. Calculation results are plotted as figures. l 1 i 1 l l l I l -. . .-

- 4. Initial Drywell Temperature is assumed to equal a uniform value of 150 F instead of the 135 F (General area temperature l
per FS AR Table 5.2-2 "Drywell Atmosphere Cooling Data Sheet") which is used in containment and decay heat removal system analysis. A higher initial temperature is conservative because less initial noncondensible mass is present in containment. Therefore, the partial pressure of noncondensible gas is less initially and less over the course of the transient and cooldown resulting in a lower value for NPSHA.
- 5. The initial Drywell humidity used is 80% versus 100% assumed in the Amendment 9 analysis as described in the reference.
- 6. A table of values for suppression pool temperature as a function of time after the accident is taken from the pool temperature curve specified.
- 7. Amendment 9 analysis was prepared before the actual piping configuration was knowm The suction line head loss used in the benchmark analysis was estimated between 4.2 and 4.7 feet. Use of the value of 4.2 feet gives good agreement between the benchmark case for Figure 14.5-10. Use of the value of 4.7 feet gives good agreement between the benchmark case and Figure 14.5-9. The actual suction line head losses are lower based on the as-built piping configuration.

To calculate the initial mass of noncondensible gas, the contribution to tne initial pressure from water vapor is subtracted. The magnitude of this water vapor contribution is a function of relative humidity p and the saturation pressure corresponding to the mixture temperature: Per Dalton's Rule: 3 Pmixture = Pgas+ $P,p} f i so Pgas =Pmixture ~ \$P,p} Equation i l is used to calculate the total initial mass in the Drywell and Wetwell airspace. As discussed above the equation is derived from the ideal gas law, Dalton's rule and the defmition of j relative humidity.

RTd RTs Equations 13a and 13b were used in the Amendment 9 analysis to calculate the percentage of the original mass of noncondensibles in containment afler 1.5 days: Eq.13a At 5% per day: M f = (0.95)'SM f= 0.926M, Eq.13b At 0.5% per day M f = (0.995)I M f= 0.9925M, The above ratio's for 5%/ day and 0.5%/ day were applied as a flat amount in An:endment 9 analysis. Although conservative, this approach is unrealistic and arbitrary.

The humidity ratio (w) can be ( used to determine the amount of dry gas contained in the vapor / gas mixture. This ratio is derived from the ideal gas law since the water vapor and gas are homogeneously mixed in the containment l volume (Drywell and Wetwell) and both the water vapor and gas are at the suppression pool l temperature. Also, the containment atmosphere is assumed to be at 100% relative humidity ; (saturated) aner the event has been initiated.

This case is the first case performed and is hereafler referred to as the " Benchmark Case" Per Amendment 9 to the FSAR, the following methodology is used: ! 1. Calculate the initial mass of air [or nitrogen] inside the primary containment assuming atmospheric pressure and a 100% relative humidity in both the Wetwell and Drywell. The l; initial Drywell temperature was assumed to be 150 F, and the Wetwell temperature 80 F. The total mass is given by Equation 12.
- 2. Assume the containment leaked at a constant rate of 5% free vol/ day for 1.5 days, the time
- required following an accident for the pool temperature to return to 130 F with one RHR l loop operating. The reduced mass is then given by Equation 13a and 13b.
! 3. Due to flow through the Drywell vents or vacuum breakers, the Drywell and Wetwell pressures will be approximately equal, i.e., Pd = Ps.
- 4. The Drywell and Wetwell airspace masses and volumes can be combined and the l containment (Drywell and Wetwell) pressure calculated as a function of the suppression pool temperature for the following reasons:
j Water from the pool is being pumped into the reactor vessel by a core spray cooling system l pump. This water is heated by the decay heat of the reactor core and pours out of the vessel via the break and into the suppression pool via the Drywell vent system. The water which returns to the Wetwell is hotter than the suppression pool water by approximately L 50 F. Because of the large flow of water involved, the low thermal capacity of the Drywell atmosphere, and the slow time rate of change of the temperature of the water flowing i through the Drywell, the Drywell atmospheric temperature will track the water temperature. I The Drywell airspace temperature will always be hotter than the pool temperature because of the elevated temperature of the break flow. l l 5. The containment pressure is then given by Equation 19. l l 6. The total NPSH available to the pumps is given by Equation 20.

E3 DATE 25-NOV-97 SHEET 39 OF 103 I l l l l Section 4.C.4 Updated FSAR NPSH Analysis and Figures I 1 1 The calculation performed to prepare the updated FSAR curves is fundamentally consistent with l that used in the " Benchmark Case" Revised inputs are utilized in this analysis per Table 9. The following methodology is used:
- 1. Calculate the initial mass of air (or nitrogen) inside the primary containment. The total initial mass is given in Section 3.C.5 as 16,315 lbm. )
- 2. Calculate the reference leakage rate Lr:
The reference leakage rate is a percentage of the initial mass of noncondensibles per unit time. So for the 1%/ day and 5%/ day cases, the reference leak rate is: L T(1%) = 16315lbm(.01/ day) = 163.15lbm day or 0.001888lbm / sec L T[5%) = 16315lbm(.05/ day) = 815.75lbm dar or 0.009442 lbm / sec
- 3. In successive steps from after the accident until the point of minimum NPSHM is passed, calculate:
Mass leakage (water vapor + gas) from containment ( m/cak ) using Eq.15 l Relative humidity to using Eq.16 i Noncondensible gas leakage from containment ( mgay ) using Eq.17 Remaining mass of noncondensible gas in containment (Alt *) using Eq.18 Containment pressure (Pc) using Eq.19. , ! This calculation is performed for: ! l 1%/ Day leakage rate - Table 12-for a 65 F seawater temperature i Table 18 for a 75 F seawater temperature j 5%/ Day leakage rate - Table 13 for a 65 F seawater temperature l Table 19 for a 75 F seawater temperature l l
- 4. Using the same suppression pool temperature data and time steps from the previous step, calculate:
Pressure provided by the remaining mass of noncondensible gas in containment (Pgas) is calculated using Eq. 21, NPSHA using Eq. 22, Pc Rey 'd using Eq. 23, NPSHM using Eq. 24. l l l

! CALC.# M462 CHECKED BY: _ REV. E3 DATE 25-NOV-97 SHEET 40 OF 103 l These steps are performed separately for the RHR and Core Spray pumps. The results are contained in the following tables: l RHR pump at 1%/ Day leakage rate - 65 F Seawater Temperature (Table 14) i RHR pump at 5%/ Day leakage rate - 65 F Seawater Temperature (Table 16) CS pump at 1%/ Day leakage rate - 65 F Seawater Temperature (Table 15) CS pump at 5%/ Day leakage rate - 65 F Seawater Temperature (Table 17) RHR pump at 1%/ Day leakage rate - 75 F Seawater Temperature (Table 20) l- RHR pump at 5%/ Day leakage rate - 75 F Seawater Temperature (Table 22) CS pump at 1%/ Day leakage rate - 75 F Seawater Temperature (Table 21) CS pump at 5%/ Day leakage rate - 75 F Seawater Temperature (Table 23)
- 5. As in the Amendment 9 methodology; due to flow through the Drywell vents or vacuum breakers, the Drywell and Wetwell pressures will be approximately equal, i.e., Pd = Ps.
The Drywell and Wetwell airspace masses and volumes can be combined and the containment (Drywell and Wetwell) pressure calculated as a function of the suppression t pool temperature for the following reasons: l Water from the pool is being pumped into the reactor vessel by a core spray cooling system pump for the 65 F case (by a Core Spray pump and LPCI pump for the 75 F). This water i is heated by the decay heat of the reactor core and pours out of the vessel via the break and into the suppression pool via the Drywell vent system. Because of the large flow of water involved, the low thermal capacity of the Drywell atmosphere, and the slow time rate of change of the temperature of the water flowing through the Drywell, the Drywell atmosphuic temperature will track the water temperature The Drywell airspace temperature will always be hotter than the pool temperature because of the elevated temperature of the break flow. l l
