C. Assumptions

1. The temperature effect on the instrumentation will be assumed to be negligible as the performance specification for the indicators list a temperature limit range of -40 F to + 180 F. [ Reference 31
2. The measuring and test equipment (M&TE) uncertainties for the flow instruments are assumed to be equal to the calibration setting tolerance of the instruments. This assumption is based on uncertainties associated with the measuring and test equipment used for calibration being less than uncertainty associated with the instrument itself per review of the most recent calibration. Reference 7 also provides the following guidance "If possible, M&TE used for field calibrations will have a tolerance four times better than field equipment, but always better than field equipment."
3. Uncertainties associated with drift of an instrument have been assumed to be equal to the calibration setting tolerance of the instrument. This assumption is based on as-found values typically within the tolerance allowed by the calibration procedure per review of most recent calibrations.
4. It is assumed that dialindicators can be read accurately to one-half of their smallest division / increment.

I TITLE: InstrumInt Uncirttinty Associstzd CALCULATION # : 96-0277 with Flow instrumentation used for IT-15 Prepared By: JAK Chill Water Pumps inservice Test Date: 12/18/96 Page 2 of 5 j D. Inputs The inservice test (IST) for the chill water pumps is performed per IT-15. The IST currently records flow from F1-4667 for P-111 A,8 and F1-4666 for P-112A,B.

[ Reference 1]

For this calculation, the total uncertainty associated with the flow l instrumentation (FI-4666/FE-4666 & FI-4667/FE-4667) used to perform the IST must be taken into account. Error contributors to this total uncertainty include:

  • Instrument Accuracy
  • Calibration Setting Tolerance e Drift
  • Indicator Readability
1. Instrument Uncertainties for F1-4666 (discharge differential pressure flow indicator, Barton Model 227). The flow indicator has a range of 0-140 gpm j which corresponds to a full scale differential pressure input range of 0-58.53" H 20. [ Reference 4)
a. Instrument accuracy; Performance specifications for the Barton Model 227 meter show an accuracy 10.5% of full scale differential pressure (0-58.53" .H 2O) [ Reference 2 & 3]. F1-4666 measures differential pressure, therefore the uncertainties given in Reference 3 are associated with the differential pressure reading. The following method was used j to convert the uncertainty seen in the differential pressure reading to an .l uncertainty in flow.

O = Constant (dP)1/2(Equation 1, See Reference 6- Appendix C)

Where, O is the Volumetric flow rate and dP is the Differential Pressure measured across the orifice Using Equation 1 recognizing that a dP of 58.53" is expected with a flowrote of 140 gpm, solve for the constant:

140 gpm = Constant (58.53")1/2 Therefore the Constant =18.3 The Uncertainty is equal to 0.5%of full scale dP (58.53") oriO.3" The dP @ 140 gpm (58.53") plus uncertainty (0.3") = 58.83" Using Equation 1 this dP corresponds to a flowrate of:

O =18.3(58.83")1/2 = 140.4 gpm The corresponding uncertainty in gpm =140.4 gpm-140 gpm = 0.4 gpm

b. Calibration Setting Tolerance; The as-left tolerance for the instrument is i2 gpm. [ Reference 41
c. Drift;12 gpm (See Assumption C.3)
d. Indicator Readability; The minor division of F1-4666 is 2 gpm in the range of concern, therefore it will conservatively be assumed that the instrument can be read accurately to within il gpm. (See Assumption C.4)
e. M&TE: 12 gpm. (See Assumption C.2)
2. Uncertainties for FE-4666 (flow orifice associated with F1-4666)

The nominal accuracy for a flow orifice is 0.6% [ Reference 5] of maximum flow (140 gpm) or 0.84 gpm.

3. Instrument Uncertainties for F1-4667 (discharge differential pressure flow indicator, Barton Model 227). The flow indicator has a range of 0-110 gpm which corresponds to a full scale differential pressure input range of 0-35.49" H 20. [ Reference 4)
a. Instrument accuracy; Performance specifications for the Barton Model 227 meter show an accuracy 10.5% of full scale differential pressure (0-35.49" H O)2 [ Reference 2 & 3]. F1-4667 measures differential pressure, therefore the uncertainties given in Reference 3 are associated with the differential pressure reading. The following method was used to convert the uncertainty seen in the differential pressure reading to an uncertainty in flow.

O = Constant (dP)1/2(Equation 1, See Reference 6- Appendix C)

Where Q is the Volumetric flow rate and dP is the Differential Pressure measured across the orifice Using Equation 1 recognizing that a dP of 35.49" is expected with a flow rate of 110 gpm, solve for the constant:

110 gpm = Constant (35.49")1/2 Therefore the Constant =18.5 The Uncertaintyis equal to 0.5% of full scale dP (35.49") = 0.18" The dP @ 110 gpm (35.49") plus uncertainty (0.18") = 35.67" Using Equation 1 this dP corresponds to a flowrate of:

0 =18.5(35.67")1/2 = 110.5 gpm The corresponding uncertaintyin gpm =110.5 gpm-110 gpm = 0.5 gpm

c. Drift;i 1.5 gpm (See Assumption C.3)
d. Indicator Readability; The minor division of F1-4667 is 1 gpm in the range of concern, therefore it will conservatively be assumed that the instrument can be read accurately to within 10.5 gpm. (See Assumption C.4)
e. M&TE; 11.5 gpm. (See Assumption C.2) i
4. Uncertainties for FE-4667 (flow orifice associated with F1-4667) l The nominal accuracy for a flow orifice is 0.6% [ Reference 5] of j maximum flow (110 gpm) or i 0.7 gpm. I E. Calculation 1

1. The uncertainties of the instrumentation described in the input section will be combined using a systematic method established in Reference 6. Reference 6 also provides the basis for identifying, quantifying, and characterizing the error effects which must be considered in the development of an instrument uncertainty calculation. This methodology does not determine the maximum i uncertainty possible, but rather determines the best estimate uncertainty.

The best estimate or realistic approach combines independent and random uncertainties using the statistical square root sum of squares (SRSS) method.

Non-random or directional uncertainties would be combined algebraically (straight sum) according to their sign with the results of the SRSS computation. However, this calculation does not contain any directional uncertainties.

OPERABILITY DETERMINATION

1. Degraded or potentially nonconforming equipment:

1 Cable Spreading Room Ventilation Chil' ? Pumps P-111 A & P-111B

2. Safety function (s) performed:

i None, pump is non-safety related. The CSR-HVAC system provides chilled water to the cable spreading room to ensure that

electrical equipment vital to post accident recovery actisities is properly cooled.

1

3. Circumstances of potential nonconformance, including possible failure mechanisms:

Condition Report 96-416 identified a potential concern for adequacy of the IST program to ensure that pumps in the l program meet design basis as well as ASME Section XI requirements. This evaluation supports determination of operability pending completion of detailed analysis.

, 4. Requirement or conunitment established for the equipment, and why it may not be met:

P-l11 A and P-11IB are integral parts af the CSR-IIVAC system. Each chilled water pump shall circulate chilled water 4

' through the cable spreading room chillect water cooling coils (HX-101 A and HX-101Bg) sufficient flowrate to exchanger heat removal requirements.

' g O ,a/P

5. How and when the potentially nonconforming equipment was first discovered:

This generic concern was first identified in June 1996 as a specific concern for safety injection pump acceptance criteria from ASME Section XI versus design requirements.

6. Basis for declaring affected equipment operable:

Pump Nameplate Data - 96 gpm @ 53' Latest IST Data - P-111 A - 101 gpm @ 51.47', IST Acceptance Range - 47.87' to 52.51' P-11IB 100.5 gpm @ 50.78' , IST Acceptance Range - 47.31' to 51.7*

i Design Basis for pump performance - 96 gpm @ 53' per 6118-M-48. P-111 A and P-11IB circulates chill water between HX- 38A and HX-101 A&B therefore the design Cowrates in these coolers must be considered.

' HX-101 A&B - Design chilled water flowrate through the coils is 48 gpm per coil @ design heat removal rate of 240,000 bru\hr (96 gpm required for 480,000 bru\hr) per specification 6118-M-37 Rev.1.

HX-38A - Westinghouse CIM #130 page 17, Performance of model PB045W - Capacity when supplied with 92 gpm is 40.2 tons. The total required flow is 92 gpm per design. (6118-M 37 Rev.1)

The maximum cooling load per Calculation WEP008.0601, Cable Spreading , HVAC Evaluation, dated 4/10/92 table 4.1 1, is 239,000 btu /hr or 19.92 tons.

The pump performance as measured by the latest IT-15 exceeds the required design flow conditions of the pump and heat exchangers therefore the pump is operable.

OPERABILITY DETERMINATION

1. Degraded or potentially nonconforming equipment:

Control Room Ventilation Chiller Pumps P-112A & P-112B

2. Safety function (s) performed:

None, pump is non-safety related. Although condnuous control room occupancy is related to nuclear safety, equipment temperature limits and habitability during plant accidents can be maintained without continuous reliance on the CR-HVAC system

3. Circumstances of potential nonconformance, including possible faik re mechanisms:

Condition Report 96-416 identified a potential concern for adequacy of the IST program to ensure that pumps in the l program meet design basis as well as ASME Section XI requirements. This evaluation supports determination of operability I pending completion of detailed analysis.

4. Requirement or commitmer:t established for the equipment, and why it may not be met:

The CR-P VAC system provides heating, ventilation, air conditioning and radiological habitability for the control and computer rooms, which are both wi$ the control room envelope.

P-1124 and P-112B are integral parts of the CR-HVAC system. Each chilled water pump shall circulate chilled water thrragh the control room duct cooling coils (HX-100A and HX-100B) a sufficient flowrate to support heat exchanger heat ,

removal requirements. l The CR-HVAC system equipment is designed to maintain a room temperature of 75 *F. Temperatare limits for equipment l are based on the most limiting component temperature range. The PBNP FSAR Section 7.2 states that " .. protective I equipment inside the room ...will provide its protective function in an ambient of 100*F. Instrumentation and associated ciremtry in the control room is generally rated for an ambient temperaturc. range of 40 *F to 120 *F.

5. How and when the potentially nonconforming equipment was first disemcred:

This generic concern was first identified in June 1996 as a specific concern for safety injection pump acceptance critena from ASME Section XI versus design requirements.

6. Basis for declaring affected equipment operable:

Pump Nameplate Data - 116 gpm @ 65' Latest IST Data - P-112A - 117 gpm @ 64.62' P-ll2B- Il8 gpm @ 63.93' Design Basis for pump performance - 116 gpm @ 55' from DBD-31 reference 10.6.8, Johnson Component Instruction

  1. 440. P-112 A and P-112B circulates chill water between HX-38B and HX-100 A&B therefore the design flowrates in these coolers must be considered.

HX-38B - Westinghouse CIM #130 page 17, Performance of model PB055W - (HX-38B) requires 120 gpm of condenser water to provide _48.8 Tons. Per Calculation WEP008.0601, Main Control Room, HVAC Evaluation, dated 4/10/92 table 4.1-1 determined a maximum cooling load of 440,000 BTU /HR or 36.67 tons. Using a linear approximation for the current capacity based on P-112A&B performance the heat removal capacity of HX-38B is 47.58 tons for the flow associated with P-112A and 47.99 tons for P-112B.

HX-100A&B - Design chilled water flowrate through the coils is 116 gpm @ design heat ren.. . Ite of 580,000 btu /hr

( 48.3 tons, DBD-31)

The pump performance as measured by the latest IT-15 exceeds the required design flow conditions of the pump however based on a linear approximation of the heat removal capabilities of HX-38B the required chill water flow is 90.17 gpm.

This is based on HX-38B's ability to remove 48.8 tons @ 120 gpm. The worst case heat load is 36.67 tons which equates (via a linear approximation) to 90.17 gpm required chill water flow. Because the current pump capacity exceeds the PDF-1553 Revuiono 36/2+94

. s maximum required flow P-112A & P-112B are operable.
