5. PURPOSE The calculation provides the uncertainty analysis for the CST level switches PS-2390A and PS2390B. It determines the level setpoint of the switches which ensures automatic transfer of the HPCI suction from the CST to Suppression Pool before CST inventory is depleted.

This revision to calculation IN1 -245 is incorporating a change to the CST low water level Suppression Pool transfer setpoint analytical limit. Reference calculation M-501. The change is being made to resolve concerns relating to vortexing in the CST resulting in air ingestion in the suction of the HPCI pump. These concerns were identified in Entergy Corrective Action Report CR-PNP-2006-01802-CA15.

The calculation will support Nuclear Change EC1 2609 and will require FSAR and Tech Spec revision.

6. CONCLUSION The calculation determined the following:

Trip Setpoint:

58 inches from tank zero, or 8.6 psig (this includes hydrostatic head pressure correction for the elevation difference between the measured level of the tanks and the location of the pressure switches; i.e. +6.5psig) see attachment 2.

>46 inches from tank zero, or _Ž8.17 psig (this includes hydrostatic head pressure correction for the elevation difference between the measured level of the tanks and the location of the pressure switches; i.e. +6.5psig) see attachment 2.

Note, the setpoint Allowable Value listed in Technical Specification Table 3.2.B requires revision. The new value is >- 46 inches above tank zero.

Setooint Analytical Limit:

43 inches from tank zero, or 8.05 (psig) (this includes hydrostatic head pressure correction for the elevation difference between the measured level of the tanks and the location of the pressure switches; i.e. +6.5psig) see attachment 2.

Setpoint Reset Value:

< 141 inches from tank zero, or S1 1.6 (psig) (this includes hydrostatic head pressure correction for the elevation difference between the measured level of the tanks and the location of the pressure switches; i.e. +6.5psig) see attachment 2 and note 4.

No Adjust Limit:

8.4 to 8.8 psig Surveillance Interval:

Once per 3 months M&TE Accuracy:

+/-0.03 psig (Specified in section 5 of PNPS Procedure 8.M.2-2.5.6)

7. INPUT AND DESIGN CRITERIA Section 7.4.3.2.5 of the FSAR describes the control scheme of the CST low level Suppression Pool transfer. It states three pump suction valves are provided in the High Pressure Core Injection (HPCI) System. One valve lines up to the pump suction from the CST and the other two from Suppression Pool. The CST is the preferred source. Upon HPCI initiation if the suction valve of the CST is closed, the initiation signal opens it. If the water level in the CST falls below the Suppression Pool transfer level setpoint, the Suppression Pool suction valves open automatically after a 3 second time delay. The time delay for the suppression pool suction valve opening is introduced to prevent false (transient) signals from initiating suction transfer. When the suppression suction valves are fully open, the CST suction valve automatically closes. Pressure switches PS-2390A and B are used to detect the CST low water level condition. Either switch can initiate opening of the Suppression Pool suction valves.

The CST suction valve does not actually receive a signal to close until after the 3 second time delay plus the cycle time of the suppression pool suction valves to fully open. The delay is insignificant with respect to the change in water level in the CST and is accounted for in the determination of the analytical limit.

i.e. CST Tank Level Change = (HPCI + RCIC Flow)(Time Delay)/(CST Surface Area)

Notes

1. The safety function of the switches is to provide signal to initiate transfer of HPCI pump suction from the. CST to suction from the suppression pool upon CST low water level condition. These switches are listed as 'Q' in the 0-List.

2. Tech Specs Table 3.2.B specifies Condensate Storage Tank Low Level Trip Function must be

_1 8" above tank zero, minimum of 2 operable Instrument Channels per Trip System. Tech Spec Table 4.2.B specifies Calibration Frequency once/3 months.

3. Per Attachment 3; the Temperature Effect (TE) is 2% of Full Range (FR.) per 100 0F. Per FSAR Table 10.9-1 and 10.9-2, maximum and minimum temperatures for the area the switches are located are 1050 F and 60°F respectively. The calibration temperature is assumed to be 70 0F. For conservatism, the larger AT is used to determine TE:

AT=105-70AT=35° F AT 35 TE--+- (2%of FR) -ATTE+/--

O -- (0.02

• 25)*

10010 TE---- 0.175 psig

4. Empirical data from obtained from the PNPS calibration records (Reference PNPS Procedure 8.M.2-2.5.6) show that PS2390A and PS2390B reset differential is within the G.E. Instrument Data Sheet Specifications for Reset Span Differential, 0.5 to 3 psid (see Reference 9). Adding the upper limit of the pressure switch reset differential span to the plant setpoint confirms the switch will not reset until after the CST level returns to a level greater than the NLL (Normal Operation Lower Limit). This will prevent opening the CST suction valve to HPCI/RCIC until this level is achieved.

5. Per the PNPS Equipment Qualification List, the pressure switches are not EQ qualified. The switches are not required to function for a harsh environment. Therefore, this calculation will be performed for normal operating conditions only.

6. The switches are seismically qualified. Per the seismic qualification test results, (see Attachment 3) the SOR switches function normally before and after seismic simulation. The vendor specifies an accuracy of +/- 1% Full Range. This value will be used in this calculation for the seismic effect (SE).

7. The Insulation Resistance Effect and Power Supply Effect are applicable to low energy analog signals and do not apply to ON/OFF mechanical devices. The switches PS-2390A&B are ON/OFF mechanical devices that open and close 125V DC contacts. These errors are not applicable to these devices.

Notes (cont.-

8. The sensor drift was statistically analyzed in Attachment 1 in accordance with ABB Impell Project Instruction 25-226-PI-001. The analysis used the data obtained from empirical data from 11/6/87 through 8/22/2007 obtained from the PNPS as-found/as-left instrument calibration records (reference PNPS Procedure 8.M.2-2.5.6). The calibration frequency of the switches for the above data is once per 3 months

• 25%. The value obtained from the statistical analysis has a probability and confidence of 95/95%.

From attachment 1, the drift value was determined to be +/-0.38 psi The sensor drift determined is considered to include the effects of measurement and test equipment (M&TE) and Reference Accuracy. Therefore, values will not be included in this calculation for M&TE Uncertainty or RA (Reference Accuracy).

9. The Condensate Storage Tanks provide the preferred supply to the HPCI and RCIC systems.

The Torus water storage provides the back up emergency HPCI and RCIC system supply. All suctions for the CST are located 10.5 feet (126 inches from the bottom of the tank; approximately 75,000 gallons) above the HPCI and RCIC suctions. Two stand pipes are in each tank, both are 10.5 feet high, one is for return water and the other is for the transfer pump supply. This ensures that there is a reserve available for HPCI and RCIC. The bottom penetration is normally lined up to the HPCI and RCIC systems.

10. Analytical Limit calculated in M-501, Rev 1, Minimum CST Level for Transfer of HPCI Pump Suction to Torus.

Analytical Limit, AL = 43 in; converted to psig (The density of water at 40 deg F is 62.426 lbs/ft)

AL 43in*62.426bs ft 3 = 1.553psig (rounded to 1.55 psig)

A~psig 1728in 3 /ft 3

11. Pressure Switch Range is obtained from G.E. Instrument Data Sheet (Cross Reference 7),

and as read from data plate on switches. Exact replacements can no longer be purchased from SOR. Current model of similar equipment has a higher adjustable range, 3-30 psig instead of 2-25 psig, see Attachment 5. Replacement of this switch with new equipment, if needed at some future date will require revision to this calculation.

12. CST overflow line at 39.5 ft. (474 inches from the bottom of the tank).

13. The External Pressurization Effect is not applicable because both sides of the pressure switch sensing mechanism are referenced to atmosphere. (i.e. Both the tank and switch are vented to atmosphere.) Therefore any change in the external or ambient pressure at the switch will be cancelled by the change in pressure at the Condensate Storage Tank.

14.The Overpressure Effect is not applicable because the Condensate Storage Tank is 40 feet high and vented. The maximum pressure of the process is within the calibration range of PS-2390A & B. Therefore, it is not possible to overpressure PS-2390A & B.

Notes (cont.)

15.The housing of the pressure switch is NEMA 4 weather tight. Pressure switches are not normally affected by humidity and the manufacture does not specify an error due to humidity variation. Therefore, the humidity effect is considered to be insignificant, HE = 0 psig.

16. The Process Measurement Effect is due to process temperature changes and piping friction losses. Neither of these effects results in a non-conservative error. The first effect is not applicable because the setpoint determination is performed assuming the process temperature (including instrument line fluid) is at 40 degrees F. The temperature of the CST water is controlled at greater than 45 OF. See drawing SM418 sh. 2 for temperature control of the CST. Conversion of the CST level in inches of water to pressure in lbs/in2 is calculated at 400 F. The density of water at 40 degrees F is 62.426 lbs/ft3. The conversion of the setpoint elevation to sensed pressure at PS2390A & B location is performed assuming the lowest temperature of the Condensate Storage Tank range of operability. This is a conservative method of analysis which results in a pressure switch measurement that corresponds to a CST level that is lower than actual. Also, fluid flowing through a piping system experiences a drop in pressure due to piping friction. The loss of process pressure due to piping friction results in a lower pressure at the location of the pressure switch which is located in the HPCI/RCIC suction piping. Reference drawing M209. This error is not applicable because it causes the pressure switch to trip at a higher CST level than required which is conservative.

8. ASSUMPTIONS CST temperature is assumed to be at the lowest value of the operating range. Refer to Drawing SM418 sh. 3. This is a conservative assumption which will result in an acceptable setpoint for all operating temperatures of the CST.

9. METHOD OF ANALYSIS This calculation is performed based on the methodology described in ENN-IC-G-003 "Instrument Loop Accuracy and Setpoint Calculation Methodology" and uses ABB Impell Project Instruction No. 25-226-PI-001 for analysis of the as-found and as-left instrument calibration data. The calculation has been prepared in accordance with EN-DC-126 "Engineering Calculation Process".

10. CALCULATION The setpoint for the CST low level Suppression Pool transfer is determined in accordance with rigor and equations prescribed in ENN-IC-G-003. The rigor as identified in ENN-IC-G-003 is type 1. The applicable equations used in the analysis follow.

AVSTM = AFT Operating Margin, OM The general form of the Operating Margin equation is:

OM = NLL - NTSP From the data in Table 7.1 the setpoint, Allowable Value and operating margin are determined using the above equations. Note, because the setpoint is decreasing, there are no biases and there is only one component in the loop being analyzed the following equations are applicable.

= 2.08 psig, or 2.1 psig (The actual plant setting is obtained by adding the head correction from Attachment 2. The plant setpoint is 8.6 psig)

The Trip Setpoint is converted to inches from the bottom of the tank as follows:

(2.1 psig) (27.73 inWC / psi @ 68 degree F) = 58.2 inches, say 58 inches The As-Found Tolerance and Allowable Value are:

As-Found Tolerance 2 2 1 AFTswRch = (DRswch +ALTswItch ) /2

= 2.1 -(0.43 + 0)

= 1.67 psig (Adding the head correction from Attachment 2, the AV is 8.17 psig)

The Allowable Value is converted to inches from the bottom of the tank as follows:

(1.67 psig) (27.73 inWC / psi @ 68 degree F) = 46.3 inches, say 46 inches Operating Margin The Operating Margin in inches is:

OM = NLL- NTSP

= (126 - 58) inches

= 68 inches

Attachment 2 PS-2390A & B Instrument Leg Head Correction Calculation Number INI -245 This attachment shows the method of solution, equations, values, tables and references used to determine "water head correction" for PS-2390NB.

Method of Solution HP = EL

• SG HP = hydrostatic head pressure EL = elevation difference SG = specific gravity of fluid EL = (elevation bottom of T1 05A and T1 05B) - (elevation midpoint of PS2390A and PS2390B)

Assumotions Elevations from drawings used are assumed to be within +/-1"; calculations will round off towards the conservative value.

Calculation elevation T1i05NB = 23ft Reference dwg. C338 Miscellaneous Structures Condensate Tank Details elevation PS2390A/B = 8.04ft Reference Attachment "K" SUDDS/RF#92-039 and verified by walkdown 12/17/98 EL = 14.96 ft elevation difference SG = specific gravity of CST water at 40°F (minimum water temperature will create largest head correction)

SG = 62.426 lbs/fte Reference ASME Steam Tables HP = (14.96ft)(62.4261bs/ft 3)
