Inspection Request Ginna SSOI IR 2003-002 Request # sm Requester:, Request:

1. Calculation DA-ME-97-045, Rev. 0 identifies as input #4.4.20 the Johnson Pump Company Certified Test Curve (bronze impeller) dated 8/17/98. The test curve is identified in the title block as having been revised by Rev # I to correct performance due to measurement error with initials R.H.D and date 9/12/20.

This curve is at 1786 rpm. Item A9.6 of the calculation indicates "from the Johnson pump curve at 1783 rpm, the nominal TDH at 5600 gpm is 161 feet" and determines a degradation ratio to be applied to the nominal pump curve based on 131.4 feet / 161 feet or 0.82. The curve at 1786 rpm indicates a TDH of 155 feet at 5600 gpm. Have the evaluations included consideration of the slight differences in rpm? Regardless of considering the 3 rpm difference, has A9.6 been updated to correspond to Rev # I to the curve? (0.82 may be a conservative result?) Rev # l of the curve indicates 135 feet a 6 0 0 0 gpm and 70 feet @7000gpm, whereas the table at A9.9 of the calculation indicates 146 and 90 respectively? Has this been updated to Rev # I of the curve? The degraded pump head in the same table is based on the 0.82 ratio above (may be conservative?) and on the higher 146 and 90 developed head (may be non-conservative?).

2. Calculation DA-ME-97-045, Rev. 0 identifies as input M.4.21 the Johnson Pump Company Certified Test Curve (SS impeller) dated 8/28/97. The test curve is identified as being at 1783 rpm and was used in the maximum flow analyses with 10 feet additional head.

CATS M07360 closure verification form indicates "(another) new pump curve from 10/15/98 testing (with SS impeller) attached. All numbers are conservatively less than DA-ME-94-045 Rev. 0 maximum pump head curve in Attachment 9...." This referenced new pump curve is at 1786 rpm whereas the 8/27/97 curve was at 1783 rpm. Did the closure evaluations include consideration of the slight differences in rpm? Without considering the 3 rpm differences, from the scale of the two curves it is difficult to determine that the 98 curve is "conservatively less" than the 97 curve - confirm this "conservatively less" statement.

3. Will calculation DA-ME-2000-036 Rev. Ifor the CCW Hx delta-P limits for Service Water flow (62-66 inch for normal discharge and 43-46 inch for alternate discharge) be on the CDs we have (do not have laptop with me w/CD capability today/tomorrow) or on the electronic system at Ginna?

If on neither, a copy is requested for Monday 4/14/03.--- H. S. Anderson

InsPection Request Ginna SSDI IR 2003-002 u Request ## de/ Requester: &rs- Date:  %'<9' Request :

1. DA-ME-91-0011 uses a figure D/G F.O. Consumption vs. Load table as its Attachment 1 which is indicated to be based on Design Input 3.2. No explanation of this table is included to indicate if a percentage on the x-axis

("Percent rated capacity (1950 KW)") of the figure such as say 100% (=I950 W e rated generator capacity) has been divided by overall generator efficiency of 0.95 to arrive at a D/G KW (1950 KWe10.95 = 2053 KW) >>> or converting to bhp = 2752 bhp which the EDG must develop and then the DIG fuel consumption at this 2752 bhp has been determined and is plotted on the y-axis ("D/G Fuel Consumption (#/HR)." If this isn't done internally in this figure, it would appear the calculation may be non-conservativeby approximately the l/(overall generator efficiency) factor. Request for Monday 4/14 the background of this figure and also documentation of manufacturer's testing of DIG consumption rates (Ibslbhp-hr! ?) and minimum fuel heat content. Recognizingthat the average of 2 EDGs' fuel consumption and total of 10,000 gallons for 2 tanks is used in the calc., when considering just the EDG#I fuel usage of 3307% or 4796 gallons, if overall generator efficiency is NOT already factored into the Attachment 1 then in Section 6.1 4796 gal.+ approx. 174 gal. (if not already considered) + 220 gal. unusable volume = 5190 gallons needed. The TS SR 3.8.3.1 requirement that each fuel oil storage tank contains >/= 5000 gallons of diesel fuel oil for each required diesel would not cover the above, without relying on excess in the other storage tank. -- For the 2 EDG's in Section 6.1 , 8846 gal + 174 gal. (if not already considered) x 2 + 220 gal x 2 = 9634 gal = OK For the 2 EDG's in Section 6.2, 9234 gal + 174 gal. (if not already considered) x 2 + 220 gal x 2 = 10,022 gal ? Section 6.1 subtracts 291 KW(e?) from the 2.5 hr. loads for DG#1 to reflect 1-SIP not operating and uses this for DG#2. What is the purpose of subtracting 246 KW(e?) from the 5.5 hrs and 32.0 hrs loads for DG#I loads to arrive at DG#2 loads? In Section 6.3, no explanation is given of why the 32,120 gal remaining is reduced to 32,099 (a conservative direction). Should the overall generator efficiency be factored in here, or has it already been? For this specific calc., it appears that 220 gal x 2 = 440 gal unusable should have been subtracted out which would have resulted in a lesser time. It appears in this calc that all DG loadings used are conservative versus the current FSAR Chapter 8 table with the exception of EDG #2 at recirculationfor 5.5 hours (1528 in calc versus 1647 in FSAR) and for 32 hours (1305 in calc. versus 1647-223 (AFW pump)=l424 in FSAR). The available fuel oil does support 24 hours of operation at 1950 W e , however the calc. does not document this specifically. Licensee Acknowledgment: L Ay/!!q bate:

2. The TS SR 3.8.3.1 requirement that each fuel oil storage tank contains >/= 5000 gallons of diesel fuel oil for each required diesel is not totally supported when (if?) usable volume is subtracted out. The wording in the bases appears to be supported (with minor wording ambiguities) in the calc.
3. EWR 4526 ME Confirm the tank dimensions are inside dimensions (uses 8 ft even and 16'1")? Confirm that drawdown to 7 1/2" inches remaining is assured. Calc. 1S07-M-01, Rev. 1 - Diesel Fuel Transfer Pump and Piping Modification Hydraulic Analysis - does not appear to consider the foot valve in the suction line from the tank in determination of NPSH for the fuel oil transfer pump.
4. DA-EE-99-097 - Pg. 15, last pgh - confirm for the measuring ruler that "indicated value of 76 inches corresponding to 5108 gallons (including a margin of 5.8 gallons ) will be used as the minimum acceptance level" - what is the 5.8 gallon margin a margin to? How is the margin determined? What was the source/development of the Gauge Chart on pg. 17 which indicates the tank is 96"diameter and 16' long (are these inside or outside dimensions? >>>

96" and 16' 1" were used in EWR 4526 ME-23).

5. 0-6.11 Surveillance Requirement / Routine Operations Check Sheet - Attachment 6 UST Storage Tank Level Log
       - This attachment indicate rounds is to inform SS of need to order fuel oil if "EDG's fuel level is -6400gals (Operability is 76 - 5109 gals)." Where is the EDG Gauge Chart available to the rounds individual? (Charts for

'V' the other two Attachment 6 readings follow as part of Attachment 6) The EDG Gauge Chart does not appear to be a part of this procedure. Minor typo in the procedure as the EDG Gauge Chart in DA-EE-99-097indicates 76' corresponds to 5108 (not 5109) gallons. Licensee Acknowledgment: $&

I. EWR 4526-ME-20, Rev I- Evaluation of Instrument Setpoints for EDG Fuel Oil System - This document uses a fuel oil consumption rate of 2.23 gpm (based on s.g. of 0.89 - other calculations of consumption use 0.82?) from a telephone memo that is attached to the document. The information in the memo is unclear if the usage is at generator ratings or at diesel engine ratings corresponding to [generator rating/overall generator efficiency]. It appears the memo may be non-conservative versus the regression figure in DA-ME-91-001, and, if overall generator efficiency should be factored in, may be even more non-conservative. The apparent non-conservatism versus DA-ME-91-001 could result in the times developed in the EWR being longer than they otherwise would be.

2. The TS SR statement that "this level ensures adequate fuel oil for a minimum of 1 hour of DG operation at 110% of full load" is not documented in the EWR (no consideration of 110% of full load is addressed, nor is a summation of times). Using information in the EWR (with additional potential conservatisms) does indicate that approximately 70 minutes of run time is provided by the available fuel below the fill setpoint 8.25" above reference 0 minus uncertainty level 0.5"=7.75" above reference 0 which would satisfy the TS SR statement.

\/

3. From the EWR it appears that physically a level on the sight glass that is 7.75" above instrument 0 (8.75" above inside bottom of day tank) would correspond to 7.75 above 'I instrument 0 for the level controValarm loop. The TS SR specifies a level of 7.75l as read on the sight glass. Please confirm that the TS SR 7.75" level marking on the sightglass physically is 7.75" above the instrument 0 for the level control/alarm loop (that is, it physically is 8.75 inches above the inside bottom of the day tank.)
4. Calc. No. 1S07-M-01, Rev. 1 indicates on pg. 6 (Special Notes) that "K values ... were increased to account for the fact that flow is not fully turbulent." The extent of this "increase" is not specifically addressed in the calculation? Are the suction foot valve and inlet screen included in the evaluation? Pgs. 7, 8, and 9 of the calculation indicate that T

the elevation difference between the bottom of the storage tank (224') and top of the day tank (256') = 12 feet. Page IIindicates the overall lift = 10 feet as used in the calculation which appears reasonable - please confirm actual elevation differences? Page 13 indicates static lift to pump suction= 8 feet which also appears reasonable - confirm elevation differences also. Licensee Acknowledgment: L Date: 54h
