1.0 Statement of Preb8;g This calculation pr?viks an analysis of NPSH conditions for the RHR and Core Spray ;

Pumps during performance test conditions and determines the margin for NPSH available i following the design basis loss of coolant accident (DBA LOCA). Proper and reliable performance of Emergency Core Cooling System (ECCS) pumps requires adequate net positive suction head (NPSH) which is defined as the absciute 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).

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 l

values for containment leakage to determine the minimum NPSH margin that will be available. The suppression pool profiles are based on the design basis recirculation line I break DBA LOCA with 65 F and 75*F ultimate heat sinks. Results from the analysis are l

presented in new FSAR figures showing the minimum NPSH margin for the low pressure i ECCS pumps following a DBA LOCA.

2.0 Summary of Results and Recommendstions Table 4 provides the suction pressure drop that is calculated for each RHR and Core 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 between the idle pump no-flow condition and with the normal pump test flow rate.

Tables 5 and 6 provide calculations of the available NPSH and margin for suppression pool temperatures of 166 F and 178 F. These are the peak suppression pool temperature for the 65 F and 75 F heat sink design cases [Refs.10 & 37). The RHR and Core Spray Pumps are provided adequate NPSH under design conditions at the peak pool temperature !

with the initial wetwell pressure of 0.5 psig. 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 wetwell pressure shown on Figures 4 and 6 (described below). Evaluation of the ECCS pump NPSH conditions with LOCA-

generated debris is included in Calculation M-734 [Ref. 40]. Conditions associated with )

the DBA LOCA are used because this event produces the highest peak in suppression pool temperature. !

Table 7 provides a calculation of the available NPSH and margin for the point of minimum

. NPSH margin following a DBA LOCA based on the results shown in Figures 5 and 7 l (described below). The 112'F data corresponds to the 1% per day leakage case and the !

119 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 65'F heat sink design case. The 115 F data corresponds to the 1% per day leakage case and the l 126 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 "pnmary 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 Technical Specification (TS) limit (1%/ day) and 5 times the TS limit (5%Iday).

Figures 5 and 7 provide graphical presentations ofNPSH margin as a function of time l after a DBA 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 pressure required to meet the NPSHa for the pump. The Core Spray pumps are predicted to have smaller NPSH margin throughout the accident response. For the 65 F heat sink '

case, the point ofleast margin for the Core Spray pump occurs during the suppression !

pool cooldown, approximately 52 hours6.018519e-4 days 0.0144 hours 8.597884e-5 weeks 1.9786e-5 months after the accident at which time Core Spray pump margin is approximately 11.5 feet. The minimum RHR pump margin occurs at approximately the same time and is approximately 17.3 feet. For the 75 F heat sink case, the point ofleast margin for the Core Spray pump occurs during the suppression pool cooldown, approximately 90 hours0.00104 days 0.025 hours 1.488095e-4 weeks 3.4245e-5 months after the accident at which time Core Spray pump margin is approximately 10.8 feet. The minimum RHR pump margin occurs at approximately the same time and is approximately 16.6 feet.

Based on the information presented, substantial NPSH margin will be available to assure reliable operation of the RHR and Core Spray pumps. Available NPSH will exceed required NPSH over the entire range of suppression pool temperatures that are predicted following the DBA LOCA. To complete an analysis for the adequacy of NPSH available to the RHR and Core Spray pumps, a debris head loss analysis must be performed for comparison to the margin for NPSH available presented in this calculation. The debris analysis and comparison to the NPSH margin is included in Calculation M-734 [Ref. 40).

3.0 Calculation of Total Suction Losses and NPSH Available

) 3.A Edethod of Solution 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 j i strainer. The suction line head loss is calculated at the conditions for temperature and ;

! pump flow rate for the pump performance In-Service 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 also predicts the NPSH available at the l ECCS pump suctions under accident conditions and the resulting margin between NPSH '

Available and NPSH Required.

A number ofvariables determine the margin for NPSH available to the pumps. Principally j they are

} Suppression pool water level, temperature, and density.

Wetwell pressure.

j Vapor Pressure of the suppression pool water.

1 Pump suction line head loss which is principally a function of geometry and flowrate

{ (which includes the clean suction strainer head loss).

[ The suction pressure drop as would be read on a pressure gage mounted at the pump i suction is also calculated. The pressure drop is the difference in the pressure read with the

pump idle (0 gpm) and with the pump at the test flow rate. This measurement method [

i - cancels out the effect of gage height versus the datum such that only the delta-P is important.

There is a maximum amount of strainer fouling that can be tolerated such that there will be i adequate NPSH to the ECCS pumps under containment accident conditions. This i calculation determines the minimum margin for NPSH available to the ECCS pumps

! following the bounding DBA LOCA. A fixed amount of the total available margin is used

- to calculate the maximum pressure drop that may be allowed during routine pump j performance testing. The allowable pressure drop for the test conditions is based on the j calculated suction line losses at the accident conditions for wetwell temperature, pressure, j and pump flow rate.

The pressure drop at the test conditions (PGAGE-STAne - PGAGE.atumG ) provides a measure i of the dynamic pressure drop caused by resistances and restrictions in the suction line plus

[ the conversion of static head to velocity head as follows:

t dP = PGAGE.srAne - PGAGE-RtWNG " Suction Line Pressure Drop + Velocity Head 1

The allowable suction dP is a fixed amount of NPSH margin allocated for surveillance i testing purposes and must be of sufficient magnitude so that it is within a reasonable measurement range c.onsidering testing accuracy and repeatability.

3.B InDut Data and Assumptions The physical configurations of the suction lines to the RHR and Core Spray Pumps are taken fiom the drawings listed in the Reference section.

The head losses due to pipe fittings are in accordance with [Ref 7].

Pipe fiiction 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 5100 gpm RHR Pump flow rate is based on the flow limitations for the RHR heat exchanger. This single pump value of flow bounds the per-pump flow for the two-pump case used in accident analyses [Ref. I1,12]. The 4400 gpm Core Spray Pump flow rate is the minimum pump runout flow rate assumed in the accident analysis (4100 gpm) plus an assumed minimum flow line flow rate of 300 gpm [Ref 11,12].

The following assumptions apply:

i

1. The RHR and Core Spray Pump accident flow rates of 5100 gpm and 4400 gpm, respectively, correspond to the flow at zero reactor pressure.

1

2. The RHR and Core Spray Pump performance test flow rates of 4800 gpm and 3300 gpm, respectively, correspond to the IST test conditions with 80F torus water.

The limiting case fer the Pilgrim ECCS suction strainers is the suction line to the RHR pump from the common ECCS strainer since the RHR velocity is greater than for the Core Spray pump, with the evaluation as follows (refer to Figure 1):

based on the total suction head losses plus the additional fixed head loss of 2 feet at the accident I conditions for wetwell temperature, pressure, and pump flow rate. The total suction heat loss (hst) is calculated at both the IST conditions for temperature and pump flow rate and for the accident conditions.

Section 4.0 Updated FSAR NPSH Analyses and Firures Section 4.A Method of Solution This section of the calculation prepares updated NPSH analysis for the FSAR. The original analysis was submitted to the AEC during the original licensing review via Amendments 9 and 24 to the SAR. This analysis was incorporated into the FSAR and remains there currently as FSAR Figures 14.5-9,14.5-10, and 14.5-13 and Section 14.5.3.1.3. He revised analysis in this calculation will be incorporated in the UFSAR by the 10CFR50.59 process.

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 the ideal gas law. The

" containment pressure required" to provide the required 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 margin. All calculation results are presented in various plots.

1. Numbers in parentheses refer to the following notes. Numbers not in parentheses refer to the corresponding references at the end of this section.

2. Initial "Drywell Airspace Pressure" is assumed equal 1.30 psig which is a conservative nommal value for drywell pressure based on a review of randomly selected summer and winter drywell pressures. Drywell pressure, temperature, and humidity along with wetwell pressure, temperature and humidity are used to calculate the initial mass of noncondensible gas inside containment. De combination of the values selected for each of these six parameters provides a conservative estimate of the initial mass of noncondensible gas.

3. Initial wetwell airspace temperature is assumed to equal the initial suppression pool temperature.

4. Initial Drywell Temperature is assumed to equal .a uniform value of 150'F instead of the 135'F (General area temperature per Table 5.2-2 "Drywell Atmosphere Cooling Data Shect") which is used in containment and decay heat removal system analysis [Ref.14]. A higher initial temperature is conservative because less initial noncondensible mass is present in containment. Derefore, the partial pressure of ncza.makasible gas is less initially and less over the course of the transient ami ecniduwii resulting in a lower (conservative)

NPSIIA calculation.

5. %c initial drywell humidity used is 20% less than that assumed in the Amendment 9 analysis. A lower humidity at a given pressure results in a higher initial mass ofimin.mniensible gas in the containment. His design value remains conservative since the drywell is initially inerted with dry nitrogen and then scaled. A leak inside containment will raise the humidity, offset by emn"wisation on drywell surfaces and the drywell cooling coils.

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 in the above table.

7. A>rierninwsit 9 analysis was prepared before the actual piping configuration was known. De suction line head loss used in the berninierk analysis was estimated between 4.2 and 4.7 fect. Use of the value of 4.2 feet gives good agreement between the berniniwrk 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. De suction line head losses are somewhat lower based on the as-built piping configuration.

8. The data table for the suppression pool temperature curve contaired in reference 37 was provided via the GE letter reference 38.

Selected data points for the suppression pool temperature as indicated in the attached tables for 75*F seawater NPSH analysis were taken from reference 38. Between 4 and 5 days,17 additional pool temperature data points were established by linear interpolation between the pool temperature at 4 days and 5 days. %cse additional data points were necessary to find the point of minimum margin which occurs before the 5th day for the 5'Nday Icakage case. Between 7 and 8 da35,9 additional pool temperature data points were established by linear interpolation between the pool temperature at 7 days and 8 days. Dese additional data points were necessary to find the point of minimum margin which occurs before the 8th day for the l'Nday leakage case.

i Section 4.C.2 Eauntions 4 An expression for calculating the initial mass of noncondensible gas inside the drywell and torus can be derived 1 based on the ideal gas law:

PV = MRT l a Sohing for the mass (M):

1 y _ PV RT ;

The total initial mass of noncondensible gas inside containment is the sum of the initial mass located in two separate volumes (torus airspace, and drywell): l Mt = Md + Ms The initial mass in each volume is composed of water vapor and noncondensible gas (air / nitrogen). To calculate

the initial mass of noncondensible gas, the contribution to the initial pressure from water vapor is subtracted.

The magnitude of this water vapor contributio s is a function of relative humidity p and the saturation pressure corresponding to the mixture temperature:

Per Dalton's Rule:

i Pmixture = Pgas +Pwater vapor so Pgas = Pmixture -Pwater vapor

= Pwater vapor and Pwater vapor = $ Psp p,p Equation 1 I 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 relative humidity. The result of Equation 11 prosides the initial mass of noncondensible gas in primary containment:

'Pd-($Pvd) (144k)Vd 9 ~Ps-($Pvs) 9 (144k)Vs l Eq.I1 Mt= + '

R Td R Ts Equation 11 is the general equation to calculate the initial mass of noncondensible gas inside containment as a function ofinitial pressure, humidity, and temperature. Amendment 9 analysis used Eq.12 which is derived from Eq.1I by setting drywell pressure equal to 14.7 psia (0 gage), wetwell airspace pressure equal to 14.7 psia ,

(0 gage), and drywell and wetwell humidity equal to 100%. Equation 12 was used to calculate the Amendment 9 !

The above ratio's for SYdday and 0.5Ydday were applied as a flat amount in Amendment 9 analysis. Although !

conservative, this approach is unrealistic and arbitrary. FSAR Appendix R (Equation R.49) prosides a rational basis for calculating the leakage from containment based on the calculated pressure during any time step, and a i reference leakage at a reference pressure.

Only a portion of the mass leaked from the containment is gas since the mixture leaking from containment is a mixture of water vapor and noncondensible gas. The humidig ratio "a)" 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 Vair=Vwater (i.e.,

the water vapor and gas are hemogeneously mixed in the containment volume (drywell and wetwell) and Tair =

Twater (i.e., both the water vapor and gas are at the suppression pool temperature). Equation 16 which prosides the humidity ratio based on the ratio of gas and water vapor pressure is derived from the ideal gas law as follows: .

This case is the first case performed and is hereafter referred to as the " Benchmark Case" Per Amendment 9 to the FSAR, the following methodology is used- 1 l

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 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 loop operating. The l 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 containment (drywell and wetwell) pressure calculated as a function of the suppression pool temperature for the following reasons

a) Water from the pool is being pumped into the reactor vessel by a core spray cooling system 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 retums to the wetwell is hotter than the suppression pool water by approximately 50'F.

b) 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 atmospheric temperature will track the water temperature.

c) The drywell airspace temperature will always be hotter than the pool temperature because of the elevated temperature of the break flow.

5. The containment pressure is then given by Equation 19.

6. The total NPSH available to the pumps is given by Equation 20.

Section 4.C.4 Updated FSAR NPSH Analysis and Finures The calculation performed to prepare the updated FSAR curves is fundamentally consistent with that used in the " Benchmark Case" Revised inputs are utilized in this analysis per Table 8.
The following methodology is used:
1. Calculate the initial mass of air [or nitrogen] inside the primary containment. The total initial mass is given by Equation 11:
)(147,000)
{15.996 - (.80(3.718))}(144 Mt= +. . . .
53.3 (610) l
)(124,500)
{l4.696 - (1.0 (.3069)}(144 b = 17316.12 lbm 33.3 (340) 1
2. Calculate the reference leakage rate L7 :
The reference leakage rate is a percentage of the initial mass of noncondensibles per unit time. So for the l'/dday and 5'/dday cases, the reference leak rate is:
L T[1%} = 17316.12 lbm (.01/ day) = 173.16 lbm / day or 0.002004 lbm / sec L T[5%} = 17316.12 lbm (.05 / day) = 865.81 lbm / day or 0.010021 lbm / sec
3. In successive steps from 100 seconds after the accident till the point of muumum NPSHM is passed, calculate:
a) mass leakage (water vapor + gas) from containment ( micak ) using Eq.15 b) relative humidity to using Eq.16 c) noncondensible gas leakage from containment ( mgas ) using Eq.17 d) remaining mass of noncondensible gas in containment (Mt*) using Eq. I 8 e) containment pressure (Pc) using Eq.19. '
This calculation is performed for a:
lYdDay leakage rate - Table 11 for a 65'F seawater temperature Table 17 for a 75'F seawater temperature )
SYdDay leakage rate - Table 12 for a 65'F seawater temperature Table 18 for a 75'F seawater temperature
4. Using the same suppression pool temperature data and time steps from the previous step,
! calculate the:
, a) pressure provided by the remaining mass of noncondensible gas in containment (Pgas) is calculated using Eq. 21, b) NPSHA using Eq. 22,
, c) Pc Req 'd using Eq. 23, I d) NPSHM using Eq. 24.

These steps are performed separately for the RHR and Core Spray pumps. The results are l
- contained in the following tables: l RHR pump at IWDay leakage rate - 65'F Seawater Temperature (Table 13) l RHR pamp at 5WDay leakage rate - 65'F Seawater Temperature (Table 15) l CS pump at 1%/ Day leakage rate - 65*F Seawater Temperature (Table 14) l CS pump at SWDay leakage rate - 65'F Seawater Temperature (Table 16) 1 RHR pump at IWDay leakage rate - 75'F Seawater Temperature (Table 19)
RHR pump at SWDay leakage rate - 75'F Seawater Temperature (Table 21)
CS pump at IWDay leakage rate - 75'F Seawater Temperature (Table 20)
CS pump at SWDay leakage rate - 75'F Seawater Temperature (Table 22)
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 pool temperature for the following reasons:
I a) 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 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 dr>well vent system. The water which returns to the wetwell is hotter than the suppression pool water by approximately 50 F.
b) 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 atmospheric temperature will track the water temperature.
c) The drywell airspace temperature will always be hotter than the pool temperature because of the elevated temperature of the break flow.

7 .. __ _ c' i Response to NRC staffquestions regarding " User Defined Inputs for ANS 5.1-1979 Decay Heat - Reanalysis Using 2a Uncertainty" which was submitted for review as i Attachment 5 to BECo letter 2.97.035 dated May 14,1997.
1. With regard to fuel enrichment, why was 4.2% selected rather than the previous value of 3.781% 7 The highest GE12 lattice enrichment was selected.
I
2. What is the basis for the isotopic fission product fractions 7 i
The isotopic fission fractions are taken from the General Electric lattice physics { code for the selected GE12 lattice. The fission fractions are typical for BWRs at i end-of-cycle, when much of the power generated is from plutonium (Pu). I i
13. The U235 fraction is seems low. Please comment on this observation.
As mentioned in the previous response, the end of cycle fission fraction for a BWR is heavily weighted to plutoniunt
4. What is the basis for the selected R factor of 0.6 7 This value is calculated by the lattice physics code for the selected lattice.

5. What is the basis for the selected Si factor (G factor multiplier) of 0.856 7 This value is calculated by the lattice physics code for the selected lattice. I

6. What is the basis for the exposure length of 32,500 MWD / ton 7 1
The 32,500 MWD / ton value is based on the most recent end of cycle core average I exposure for a Pilgrim Nuclear Power Station GE12 fuel cycle. l l Enclosure 2 i l l J
