Discussion and Pu ose I 4 T lculation is being revised to correct the error of using gauge instead of absolute terms when calculating for the centrifugal charging pump taking suction from the volume control tank (VCT) during normal operation. The format is also updated to current convention and for clarity. Although the original calculation was in error, the error was in the conservative direction wherein the calculated NPSH available (NPSHa) was one atmosphere or 34 ft below the actual value. Therefore the actual margin is 34 ft higher than calculated.

Desi n In uts and Data Sources

1. Elevation of VCT outlet pipe flange = 611'-0-1/40 = 611.02', per Drawing 1-5441-12, B/8 2, Elevation of pump centerline = 590'-9" = 590.75', per Drawing 1-5443-23, C/5.

3. Elevation of Pump suction nozzle is 20" above the centerline, per Pacific Pump Drawing PC-45605

= 590'-9" + 20" = 592'-50 = 592.42'.D 3I Note; Max normal operating flow is letdown flow of 120 gpm (max) plus 60 gpm miniflow, all per UFSAR table 9.2-2, plus 24 gpm seal return flow, per assumption 5 below, for a total fiow of 204 ~ m.

Method The NPSHa is defined as the total suction head in feet of liquid absolute, determined at the suction nozzle and referred to datum, less the absolute vapor pressure of the liquid in feet of liquid pumped.

Therefore; (1) NPSHa = Ha - Hvpa+ Hs, per Hydraulic Institute Standards page 41 Where Ha = atmospheric pressure in ft absolute (14.7 psi or 34 ft)

Hvpa = vapor pressure of liquid in 6 absolute Hs = total suction head in ft (2) Hs =Z+P/y-Hf Where Z = elevation of liquid in tank above pump suction nozzle in ft P/y = tank pressure in psig converted to ft of head by the density factor.

Hf = pipe &iction in ft between the tank and the pump suction nozzle.

Note; the pipe friction computed for the original calculation will be used for this revision.

The friction value for flows other than the 98 gpm used in the original will be calculated based on the square relationship of flow to friction as shown in the Darcy-Weisbach equation lHf = f(L/D)(V/2g), eq 2-8, pg 2-8 Crane, that is; (3) Hfz =Hfi(Q2/Ql) . ENS/141 Let07/s1 r I W

~

Acce tance Criteria able operating conditions exist when the NPSHa exceeds the NPSHr.

A~i

1. Based on review of the values, the friction value used in the original calc is assumed to be correct.
2. The level in the VCT is conservatively assumed to be below the low level alarm and actually out of the tank.
3. The liquid temperature is conservatively assumed to be 190 ', 5 ' above the highest procedural limit.
4. It is assumed that the values calculated based on the piping configuration of the unit 1 East pump are applicable to all 4 pump installations. This assumption is made since the slight differences in the unit 1 West and both unit 2 pumps are considered insignificant relative to magnitude of the margin of 12 ft.
5. The extremely conservative assumption that the seal leakoff on all 4 RCPs is at the maximum 6 gpm instead of the nominal 3 gpm. Procedure Ol-OHP 4022.002.001, Rev 8, C. S. 1, steps 3 &, 15 trips the pump and the if unit the flow on any one RCP rapidly increases to 6 gpm (the max reading on the flow instrument). We are assuming the unprecedented condition where the flow on all 4 RCPs reach 6 gpm simultaneously..

Calculation late the NPSHa at a flow of 204 gpm, at 190 deg F

1. Establish the friction (Hf) at 204 gpm based on the original HFLC2 computer calc at 98 gpm.

Hfi = total friction of the four series segments 1 through 4 from the VCT to the pump at 98 gpm

= 1.12+ 0.04 + 0.01 + 0.05 = 1.22 ft

=

Hf> friction of the segments at 204 gpm

= Hfi(Q2/Ql) [eq 3] = 1.22ft x.(204/98) = 5.29 ft

2. Calculate total suction head Hs = Z + P/y - Hf [eq 2] = (611.02' 592.42') + 0 - 5.29' 13.31 ft
3. Calculate NPSHa NPSHa = Ha - Hvpa+ Hs [eql]

vapor pressure of water@190' = 9.340 psia per Crane, Pg A-6 weight density of water @ 190 ' = 60.343 8/ft per Cran'e, Pg A-6 therefore Hvpa = P/y = 9.340 psia/(60.343 0/ft /144in2/ft ) = 22.29 ft NPSHa = 34- 22.29+ 13.31. = 25.02 ft, use 25 ft

4. Margin of NPSHa over NPSHr = 25 - 12 = 13 ft Summa of Results and onclusions Adequate NPSH exists at the extreme worst case bounding conditions reviewed in this revision since the NPSHa well exceeds the NPSHr with a margin of 13 ft.

KNSM 720719FK Rev.l Alternate Calculation Verification XNPUTS

1. Proto-Flo Version 3.04 Model for CVCS Normal charging floiv path developed

¹ for approved Calculation ENSM961213AF Rev. 1, Approval Date 5/28/97.

2. Model inputs Specific to Charging Pump NPSH Calculation ¹ ASM 720719FK Rev. 1 under worst case normal operating conditions.

~ Suction Temperature 190 '

~ VCT Pressure 14.7 psia

~ 'eal water injection flow 44 gpm Charging header flow 100 gpm

~ CCP mini-flow in service (model calculated flow at 57.24 gpm vs the 60 gpm assumed by calculation initiator)

Discussion Charging Pump NPSH calculation was verified using a previously approved Proto-flo model of the CVCS system under calculation ENSM 961213AF Rev. 1. Model inputs were revised slightly to reflect inputs used by calculation ENSM 720719FK Rev. 1.

The revised inputs are stated under item ¹2 of the inputs listed.

The revised Proto-flo model was run 7/6/98 on a Dell computer model =:.'XMT5133,

¹ AEP specific PC 6738. Results of this alternate calculation along with a CVCS System Nodal Model Drawing have been attached with the Verification Check List. The Proto-flo model automatically calculates NPSHa and compares the value against the NPSHr curve which was input as part of the model design. The verification calculation confirtns within one ft the results obtained under ENSM 720719FK Rev. 1
