1.0 PURPOSE DRE97-0010 REV. 0 PAGE The purpose of this calculation is to determine if sufficient Net Positive Sl,lction Head (NPSH) is 4
available to the Dresden LPCI and Core Spray (CS) pumps following_ a DBA-LOCA. This calculation examines NPSH conditions under long-term (> 600 seconds) conditions following the accident. *The results of this calculation will be used to support a Dresden License Amendment request. Upon approval ohhis request, this calculation will represent a Design ~asis Document.
2.0 METHODOLOGY AND ACCEPTANCE CRITERIA The minimum suppression pool pressure required to meet LPCI/CS pump NP.SH requirements will be determined ~nder long-term post-LOCA conditions: The minimum pool pressure r~quired will then be compared to the suppression pool pressure available post-LOCA (Ref 1). If the pr.essure available is greater than the pressure required, then adequate NPSH exists and pump protection is ensured. If the available pressure is less than the pressure requited, then the potential exists for the pumps to cavitate. In these situations, LPCI pump flows will be reduced to below-nominal values and new cases will. be run to establish the ability of the operator to throttle the pumps to an
- acceptable condition.
, r This acceptable condition is defined by the following criieria:
- 1) Adequate NPSH to the pumps - minimum suppression pool pressure available is greater than minimum pressure required for the LPCI and .CS pumps.
' ,i
- 2) Adequate containment cooling - the minimum containment cooling flow analy:zed is SOOO gpm total LPCI flow through a single LPCI heat exchanger.
I '.. .~
Various LPCl/CS pump combinations will be explored to determine the bounding NPSH case for the LPCI and Core Spray pumps. It will be show11 that the 4 LPCI/2 CS pµmp combination is the bounding NPSH case. This calculation is bounding for. NPSH due to use of the following conservative inputs:
- Maximum suppression pool temperature response - Reference 1 d.etermines *
- maximum. suppression pool temperatures post-LOCA, thus maximizing the vapor pressure and minimizing NPSH margin.
- Minimum suppression pool, pressure response - Reference I utilizes inputs that minimize suppression pool pressures post-LOCA, thus minimizing overpressure credit and minimizing NPSH margin.
- Technical Specifications minimum suppression pool level including drawdown, minimizing elevation head and minimizing NPSH margin
- increased clean. commercial steel suction piping friction losses by 15% to account for potential aging effects. thus maximizing suction losses
- ICALCULATION NO.
3.0 ASSUMPTIONS DRE97-0010 REV. 0 PAGE 5
- l. It is assumed that at 10 minutes into the accident, operator action will be taken to ensure that the LPCI and CS pumps have been throttled to their rated flows of 5000 and 4500 gpm respectively. This condition will be referred to as the "noininal flow" condition.
- 2. LPCVCS pump suction piping friction losses (excluding strainer losses) were developed for a single flow case using a FLO-SERIES model of the Dresden ECCS ring header and pump suction piping (Ref 4). This model was then run at the various Ll'CVCS pump combinations and flows as required* to support the cases evaluated in this calculation (Attachment A). The model that .was developed uses clean, commercial steel pipe. In order to compensate for the increased loss du~ to the potential effects of aging, the resulting friction losses from the model were increased by*J.5%. This is consistent with discussions provided in References 14 and 15.
- 3. To account for strainer plugging, on~ of the four torus strainers is assumed 100% blocked,.
while the remaining three strainers are assumed clean. While the torus strainers
- are not included in. the FLO-SERIES* model discussed .in Assumption 2, blocking a strainer translates to blocking *a torus-to-nng header entrance leg. This is accomplished in the model by closing one of the torus legs (Torus 1-4). Based on preyious sensitivity analyses, Torus-4 was chosen for maxim.um effect on both LPCI and Core Spray suction losses for all pump combinations.
- 4. The calculations in Reference l have been performed to minimize the extent of overpressure
. that would exist post-LOCA, and support the conclusion that overpressure would be available and can be employed to demonstrate adequate* LPCVCS NPSH performance. These calculations are more appropriate with respect to the prediction of minimum containment pressure than are the original design basis calculations. While different decay heat standards and heat exchanger perf9rmance predictions are applied in these calculations, the peak containment temperatures being predicted *are consistent with the original design basis temperature predictions. The pressure response is not a function of decay heat models, but is primarily only affected by the pool temperature and heat exchanger performance. The new calculations incorporate analysis ass~mptions to minimize overpressure that are consistent with NRC Information Notice 96-55. The. use of the Reference 1 data is thus conservative with .
respect to overpressure and minimizes NPSH margin.
- 5. NPSH Required (NI>SHR) curves are provided for the LPCI and Core Spray pump on the respec.tive vendor* pump curves (Refs. 12, 13). The NPSHR curves are provided from 3000 gpm to 6000 gpm pump flow. It is assumed that the NPSHR at 2500 gpm is the same as the NPSHR given at 3000 gpm. While it is recognized that the NPSHR may rise slightly at lower flows, 2500 gpm represents a mid-rang~ flow point for this pump and the NPSHR is expected to remain constant in this flow region.
ICALCULATION NO. DRE97-0010 REV. 0 PAGE 6 4.0 DESIGN INPUTS
- 1. Initial suppression pool temperature is 95°F (Ref 3). This is .the maximum allowable
- suppression pool temperature under normal operating conditions. This value is used as the initial pool temperature in Reference 1 to maximize suppression pool peak temperature, and is used as a minimum temperature during the LOCA in Reference 4 to maximize piping friction losses (maximum viscosity).
- 2. Numerous long-term suppression pool temperature and pressure responses were generated in Reference 1 based on a containment model developed by GE. The intent of these cases was to determine the maximum pool* temperatures expected* post-LOCA, and to vary the inputs in ,
such a way as to produce a coupled minimum pool pressure response. In this manner, the temperature-pressure combination that is bounding for NPSH was determined to be Case 2Al-
. 20% mixing. A tabular representation of the suppression pool temperature/pressure responses for this case is provided in Reference 2 and is summarized in Tables I and 2 of this calculation.
- 3. LPCI and CS pump suction piping friction losses (excluding strainer losses) from the torus strainers to the pumps were developed in Reference 4 using a FLO-SERIES model of the ECCS ring header and* s.uction piping. This piping model was then utilized for the various LPCl/CS pump combinations and flows as required to support the cases evaluated in this ca!Culation (Attachme~t A) .
- 4. The minimum torus level elevation with a maximum drawdown of 2.1 ft. is 491 '5", or 491.4 ft.
- (Ref 5). At the. time of peak suppression pool temperature, a recovery of I. I ft. occurs, resulting in a net drawdown of 1 ft (Ref. 6). This ~epresents a.torus level elevation of 492.5'.
- 5. The torus strainers have a head loss of S.8 ft.@ 10,000 gpm clean (Ref. 7).
- 6. LPCI and Core Spray pump centerline elevation is 478.1 ft. (Refs. 8, 9).
- 7. NPSH Available (NPSHA) is calculated using the following equation:
NPSHA = 144 V (Pi - Pv) + Z - hL - h,train (based on Ref. 10, p. 2.216) where: Pi - suppression pool pressure in psia Pv = saturation pressure in psia V = specific volume in ft 3/lb h1. = suction friction losses in feet h,1rain = head loss across strainer In feet Z . = static. head of water above pump inlet in.feet I
- 8. Saturation pressures and specific volumes at various temperatures are taken from Reference I I and are included in Tables 1 and 2.
- 9. LPCI pump NPSHR.is 30 ft. at 5000 gpm. 25 ft. at 2500 gpm (Ref. 12, Assumption 5):
- 10. Core Spray pump NPSHR is.27 ft. at 4500 gpm (Ref. 13).

6.0 CALCULATIONS DRE97-0010 REV. O The equation presented in Design Input 7 can be rewritten to solve for the minimum suppression PAGE 8 pool pressure required to meet pump NPSH requirements by setting the NPSHA equal to the NPSHR as follows:
Pt.., min = z CNPSHR- + h1ou1} + Pv ( l) 144 v where htobl = friction (hL) + strainer (hstrain) loss (Attachment A) hstrain = 5:8 ft.@ 10,000 gpm clean (Design Input 5) z = 492.5 ft. - 478. l ft. = 14.4 ft. (Design_ Inputs 4, 6)
NPSHR = 30 ft.@ 5000 gpm for LPCI (Design Input 9) 27 .ft. @ 4500 gpm for CS (Design Input l 0)
Solving Equ.ation l, the minimum suppression pool pressure required to meet LPCI and CS pump NPSH requirements under a spectrum of pump combinations is calculated and the, results presented in Tables l and 2. These results are plotted in Figures l and 2 along with the*available suppressi~n pool pressure (Ref 2). All the combinations evaluated involve* 2 CS p~mps. Thes~
cases bound the respective single CS pump scenarios due to the higher ring header/strainer losses of the 2-pump cases and no pool temperature benefit (c~oling) from the added Core Spray pump.
It can be seen that adequate NPSH is available to meet cs* pump requireme11ts post-LOCA for all pµmp combinations (Figure -2). However, the potential exists for the LPCI pumps to cavitate in the 4/2 and 3/2 pump nominal flow scenarios (Figure l ). For these latter cases, throttling of the LPCI pumps may be required. to ensure NPSH requirements are met. Addition.al cases are provided to establish. the ability of the operator to throttle the LPCI pumps to an acceptable condition as defined in Section *2.0 (Table 2). *These results, plotted in Figures 3 (LPCI) and 4 (CS), indicate that for all pump combinations, the LPCI pumps can be throttled to ensure pump.

SUMMARY
AND CONCLUSIONS An NPSH analysis was performed for the LPCI/CS pumps under long-term post-LOCA conditions as outlined in Reference l. Selecting inputs to* minimize NPSH margin, it was determined that adequate NPSH exists to meet CS pump requirements for all pump combinations.
However, the potential exists for the LPCI pumps to cavitate in the 4/2 and 3/2 pump scenarios.
For these cases. throttling of the LPCI pumps may be required to ensure NPSH requirements are met. Specific cases involving throttled LPCI pumps were evaluated to establish the ability of the operator to throttle the pumps to an acceptable condition. Under all post-LOCA pump combinations, positive NPSH margin could be obtained by throttling. the available LPCI pumps.
