1.0 PURPOSE The purpose of this calculation is to calculate an allowable value and nominal trip setpoint for the drywell pressure high setpoint in the Technical Specification. The loop(s) consist of the instruments 1B21-PT-N094-A,B,E,F and 1B21-PIS-N694A,B,E,F for Div.

I and II, instruments I B2 1-PT-N067C,G,L,R and 1B2 1-PIS-N667C,G,L,R for Div. III.

2.0 DESIGN REQUIREMENTS The System B21 high pressure trip instrumentation (Ref. 3.1.12, 3.2.3, 3.2.4) provides for the following:

" Closure of Group 5 valves (E12-FO1 IA[B], E21-F012, E12-F024A[B], E12-F028A[B], E 12-F021, E61-FO03A[B], E61-FO05A[B], E6 1-F007, E6 1-F020) for containment/drywell isolation.

" Closure of Group 6B Valve No. E22-F023 for containment isolation.

" Logic inputs for closure of Group 9 Valve Nos. E51-F077, E51-F068 and E51-F078 for containment isolation.

" Initiation of LPCS and start of Div. 1 diesel.

" Initiation of RHR C (LPCI Mode) and start of Div. 2 diesel.

" Logic inputs for initiation of RHR A and RHR B in the LPCI mode and opening of injection Valve Nos. E12-F042A, B & C and E21-F005.

" Logic inputs for energization of ADS pilot valves A and B and opening of ADS valves.

" Initiation of HPCS and start of Div. 3 diesel.

" Initiation of LPCS and LPCI A and logic inputs for operation of Valves Nos. E 12-F028A and E 12-F042A.

" Initiation of LPCI B & C and logic for operation of Valve Nos. E 12-F028B and E12-F042B.

" Logic inputs for opening of Valve Nos. E30-FOOIA[B] and E30-FO02A[B] (upper containment pool dump to suppression pool).

" Logic inputs for trip of Feeder Breakers ESF12, ESF21, ESF 1I

Design Basis Event (DBE)

The drywell "HI" pressure measured by 1B21-PT-N094A,B,E,F, 1B21-PIS-N694A,B,E,F and I B2 1-PT-N067C,G,L,R, 1B2 1-PIS-N667C,G,L,R will provide the actions summarized by calculation section 1.2 whenever the trip setpoint is reached regardless of the cause. Instantaneous guillotine rupture of a recirculation or main steam line, intermediate size liquid line rupture, small size steam line rupture or loss of drywell cooling are included as possible causes (Ref. 3.2.5). These loops are required to operate under normal and accident conditions and are designed to Seismic Category I requirements for operation during and after a SSE event. The instruments in these loops are classified as QF I (Ref 3.2.2). Therefore, accident uncertainties will be evaluated in this calculation. Per Reference 3.1.31, seismic effects are not required to be considered for setpoint loops because the reactor will be shutdown following a seismic event.

Therefore seismic effects will not be considered for the subject loops.

JIM ~ CALCULATION SHEET ENTERGY SHEET 15 OF 41 CALCULATION NO. JC-011B21-N694-1 REV. 1 5.0 ASSUMPTIONS 5.1 All uncertainty values are assumed to be 2 sigma values unless specified otherwise (Ref. 3.1.3 1).

5.2 Per reference 3.1.31, the M&TE error is normally assumed to be equal to the reference accuracy of the transmitter. Per references 3.1.15, 3.1.16 and 3.1.32, a Fluke 45 (+/- 0.040 ma) and a pressure gauge (+/- 0.0125 psi) are used to calibrate the transmitters. The total M&TE error for this device is the SRSS of the two.

Converting the ma error to psi: (0.040 ma)(5/16 ma) = +/- 0.0125 psi. The SRSS of 0.0125 and 0.0125 is +/- 0.0177 psi. The setting tolerance from references 3.1.15 & 3.1.16 is + 0.04 ma, or +/- 0.0125 psi. Since the test equipment error is greater than the reference accuracy of the transmitter (+/- 0.0084 psi) and the setting tolerance, +/- 0.0 177 psi, shall be assumed for the M&TE error.

Per references 3.1.17, 3.1.18 and & 3.1.5, a Rosemount readout assembly (+/- 0.01 ma) is used to calibrate the Rosemount trip units. The accuracy of the readout assembly (MTE 2 ) is equal to (0.01 ma)(5/16) = +/- 0.0032 psi and the accuracy of the trip unit is +/- 0.20% span = 0.20% (5 psi) = +/- 0.0100 psi. References 3.1.17

& 3.1.18 specify a setting tolerance of+/- 0.04 ma = (0.04)(5/16) = +/- 0.0125 psi.

The larger value, + 0.0 125 psi, will be assumed for the M&TE error.

5.3 A maximum value of 28 vdc and minimum of 23 vdc will be assumed for power supply variation, as this is the value provided in reference 3.1.10 for the 24 vdc power supplies. This results in an assumed voltage variation of +4, -1 vdc. Per reference 3.1.30, some of the loop power supplies were replaced with Vicor model VI-N53-IM DC-DC converters that have a maximum variation of 0.55%,

which is bounded by the original power supply variation. For conservatism, +4 vdc will be used in this calculation.

5.4 Environmental Uncertainties for the transmitters are assumed to be determined by normal environmental conditions. The response time for instantaneous guillotine rupture of recirculation line or main steam line is approximately 1.1 seconds for a 20 psig drywell pressure. For intermediate size breaks, drywell pressure increases at a rate of approximately 1 psi/sec, to a pressure of approximately 4 psig at 5 seconds. For these scenarios, the trip system response time can be considered to be no greater than 5 seconds including a measurement loop response time of approximately 0.6 seconds. For small line breaks, the drywell pressure is assumed to rise at a relatively slow rate resulting in a trip of the System B21 high drywell pressure instrumentation. Containment pressure and temperature are assumed to remain at their normal operating values until the trip occurs. (Ref. 3.2.5, 3.1.11) 5.5 Specification E-100.0 (Ref. 3.1.2) states that froth will exist in rooms 1A3 11 and 1A313 up to elevation 141' 10". The transmitters used in this application are

mounted in local panels located on elevation 136'. The instruments are typically mounted at least 4' 6" above the floor (Ref. 3.1.13). Due to the fact that these transmitters are located at the upper fringe of the expected froth and the exposure to the froth would be a minimal time, the temperature uncertainty of the transmitter is assumed to be bounded by a 5 second function time except for conditions resulting from a small line break in the drywell. For a small line break, environmental conditions for rooms 1A3 11 and I A3 13 (containment) are the same as normal.

5.6 The transmitter(s) monitor containment air absolute pressure directly using a minimal amount of instrument tubing. Since this is a pressure measurement, changes in the containment air density will not affect the transmitter uncertainty.

Therefore, the process measurement uncertainty is assumed to be zero for the calculation. (Ref. 3.1.14) 5.7 This loop does not employ a primary element separate from the sensor.

Therefore, no additional uncertainties due to inaccuracies in the primary element exist and PE = +/- 0 5.8 Prior to trip of the drywell pressure high trip the temperature and humidity for rooms 1A311 and 1A313 will be "normal" therefore the effect caused by insulation resistance change is negligible.

5.9 Radiation effects are determined in reference 3.1.28, section 5.1 for Rosemount model 11 53B transmitters located in zones 1A3 11 and 1A313 as being 0.15%

URL. Reference 3.1.27, section 4.1, states that the radiation effect for the 1153D would be identical to the 11 53B, therefore the radiation effect for these transmitters is assumed to be 0.15% URL.

5.10 The drywell pressure measurements by the transmitters 1B21-PT-N094A,B,E,F and 1B21-PT-N067C,G,L,R are made using transmitters designed for absolute pressure measurement. The high drywell pressure setpoint is therefore established as an absolute pressure value. However, to assure that established drywell pressure limits are not exceeded these absolute pressure valves require adjustment to assure that the drywell pressure analytical limits expressed as pounds per square inch gage (psig) are not exceeded.

The technical specification pressure setpoint values are given as gage pressure reference to a site average barometric pressure of 14.70 psi. However, the pressure setpoints must be determined using a worst case barometric pressure value of 14.17 psia to assure that the established analytical limit is not exceeded.

(Ref. 3.1.11, Page 26, Note 6) (Ref. 3.1.15) 5.11 Over Pressure Effects refer to those uncertainties that may occur when pressure transmitters see pressures beyond their upper range limit prior to performing their required function. The pressure prior to instrument loop trip will be less than the upper range limit.

A ENTERGY CALCULATION SHEET SHEET 17 OF 41 CALCULATION NO. JC-011B21-N694-1 REV. 1 5.12 Since Rosemount 51ODU model is obsolete, they may be replaced with 71ODU's in the future (Ref. 3.1.29). The performance specifications for the 710DU are equal to or better than those of the 51 ODU.

5.13 The accuracy of the Rosemount trip units (+/-0.20% span) is valid for six months (Ref. 3.1.5). The trip units are calibrated every 115 days (Assumption 5.14).

Therefore, drift is included in reference accuracy.

5.14 A calibration interval of 30 months will be assumed for the transmitters, which is the nominal 24-month period, plus a 25% grace period (Retf 3.1.31). A calibration interval of 92 days plus a 25% grace period (115 days) will be assumed for the trip units (Ref. 3.1.17 and 3.1.18).

5.15 The radiation drift for the transmitters and trip units is assumed to be negligible because of the low normal dose rates. Per reference 3.1.1 section 2.4, there are no radiation effects on 1153B transmitters below 0.1 Mrad. Since 1 153D transmitters are expected to have the same radiation effects as the 11 53B (Ref.

3.1.27), no radiation effects are assumed for the 11 53D transmitters below 0.1 Mrad.

5.16 Variations of process characteristics do not affect the pressure sensed by the pressure transmitter. Therefore, PM = +/- 0.

5.17 Static Pressure Effects refer to those uncertainties that may occur when differential pressure transmitters are used at elevated process pressures. This effect does not apply to absolute pressure transmitters.

RA - reference accuracy L - negative bias uncertainty (applies to increasing setpoints only)

M - positive bias uncertainty (applies to decreasing setpoints only)

MTE - measurement and test equipment inaccuracies D - drift 6.2 Loop Uncertainties The random and bias components of:

PE - errors associated with the Primary Element PM - errors in Process Measurement, and IR - errors due to degradation in Insulation Resistance will be quantified, the loop error equation given, and the device and loop uncertainties combined to produce:

AL - SRSS of all device random uncertainties except drift LL - The sum of all negative bias uncertainties ML - The sum of all positive bias uncertainties CL - SRSS of all measurement and test equipment inaccuracies used for calibration.

DL - SRSS of all drifts LU - SRSS( AL, CL, PE, PM )IR - LL + ML 6.3 Total Loop Uncertainty The total loop uncertainty will be calculated using the reference 3.1.31 equation:

TLU = LU + DL 6.4 Allowable Value The allowable value for the loop will be calculated using the reference 3.1.31 equation:

AV= AL +/- LU

6.5 Nominal Trip Setpoint The nominal trip setpoint will be calculated using the reference 3.1.31 equation:

NTSP = AL +/- TLU 6.6 Spurious Trip Avoidance The probability of a spurious trip during normal plant operation using the Tech Spec setpoint will be evaluated using the methodology of reference 3.1.31 and calculated loop errors. Per reference 3.1.31, a 95% probability of no spurious trip is acceptable. Per reference 3.1.3 1, a Z of 1.645 corresponds to a probability of 95%.

6.7 LER Avoidance The probability of exceeding the Tech Spec allowable value without a trip at the tech spec setpoint will be evaluated using the methodology of reference 3.1.31 and calculated loop errors. Per reference 3.1.31, a 90% probability of avoiding LERs is acceptable.

Note: When considering the probability of a spurious trip, any late actuation will be conservative. Similarly, when considering the probability of an LER, any early actuation will be conservative. This means that single sided distributions are appropriate for this evaluation. Per reference 3.1.3 1, a Z of 1.28 corresponds to a probability of 90%.

6.8 Nomenclature The nomenclature of reference 3.1.31, Section 1.6, will be used. Errors associated with the transmitter will be subscripted with a "1", errors associated with the trip unit will be subscripted with a "2", while loop errors will be subscripted with an "L". For example, D, would be the transmitter drift, D2 would be the trip unit drift, and DL would be the loop drift.

= 16.67 - 0.0529

= 16.61 psia Per section 2.0, the technical specification allowable value is < 16.11 psia.

Therefore the technical specification AV is conservative with respect to the calculated value.

7.9 Nominal Trip Setpoint NTSP = AL - ITLUI

= 16.67-0.1509

= 16.51 psia

Per section 2.0, the technical specification NTSP is < 16.06 psia. Therefore the technical specification NTSP is conservative with respect to the calculated value.

• SRSS (0.0485, 0.0217, 0.0977)

= 0.0557 The highest probability of spurious trip exists when the process is at the point in its normal band closest to the setpoint, the Limiting Normal Transient (XT). A spurious trip will occur when the loop uncertainty is equal to or greater than the difference between this Limiting Normal Transient and the trip setpoint.

Maximum differential pressure between the drywell and auxiliary building is 1.0 psid (Ref. 3.2.1). During normal operation, the maximum pressure in the auxiliary building is 0.25 inwg = 0.0091 psi (Ref. 3.1.2). Therefore, the Limiting Normal Transient for the trip setpoint is 15.7 psia (XTs = 0.0091 + 1.0 + 14.67).

When an enveloping value of XT is used, the appropriate value of GN is zero aN = 0 Z = ABS(16.06 -15.7) / SRSS(0, 0.0577)

= 6.23 This is above the Section 6.6 minimum acceptable Z value of 1.645 for 95%.

= 0.897 The calculated Z is less than 1.28 and therefore does not meets the acceptance criteria of 90% LER avoidance. However, LER avoidance does not have to

include uncertainties associated with accident conditions. Therefore AL shall be recalculated based on normal plant conditions (AL').

Various measures are suggested below to reduce the uncertainty values and to provide a solution. However, because of the very small margin in this parameter, solution to this problem could require adjustment to the Allowable Value and / Or Nominal Trip Setpoint.

2 K. Melson EXCEL For information, it appears as though 8/10/12 None Required N/A Services Corp. the temperature effect is the largest uncertainty term for this instrumentation, which is driven by the high tum-down factor.

Services Corp. acceptable resolution may not be possible by merely reducing the uncertainties, and changing the required operating conditions, as suggested below. If this proves to be true, the calculation should be prepared in an approach that establishes new, acceptable values.

Thus, the calculation wilt not use the old values for AV to compare fbr the Z values, etc. It should be positively presented, and then possibly shown at the end that the AV and NTSP (as appropriate) need to be changed.

Note that the approach employed (using the greater of the actual M&TE, setting tolerance, or reference accuracy of the device being calibrated) is not covered in the JS-09 methodology.

[For this project, we recommend across the board that the procedures be changed, so that M&TE and Setting Tolerance are equal to or less than RA for the calibrated devices.

From the TSTF-493 perspective, this will simplify implementation. This should also be considered in Sections 5.2 and 6. Use of this approach would slightly reduce calibration errors.]

14 K. Melson EXCEL Section 5.9: First line, the reference 8/10/12 3.1.28 is correct.

Services Corp. to 3.1.28 would appear to be an incorrect reference for this information. Would suggest that it could need change to 3.1.27. Also, I don't think 3.1.27 will specifically refer to zones IA311 and 1A313.

Need to quantify radiation value from 3.1.2 (or another plant document), and then compare to the tested values in 3.1.27 for applicability.

accident effects. This may not be significant, as this is a fast trip. The actual radiation dosage could be computed for the subject accident over the short term that the device must function. This is generally a fairly small number. If the accident dose could be shown to be less than 104 R before the time of required trip, radiation effects could be removed; i.e.. considered neg*ligible.

16 K. Melson EXCEL Section 7.1: For consistency in 8/10/12 Four decimal resolution will be used.

Services Corp. resolution with the other terms, the Radiation Effect should be 0.0406.

Power Supply effect should be shown as 0.0010 psi and the Seismic Effect should be 0.1353 psi. Drift should be shown as 0.0899 psi.

Actually, just need to be consistent on the number of decimals for resolution. This will slightly change the answer for A 1. which should also be expressed to 4 decimal, since the other intermediate terms later are as well.

17 K. Melson EXCEL Significant math error at the end of 8/10/12 TD has been revised using 3-sigma Services Corp. Section 7.1: When DI is computed, reduction factor. Correct value used in the term, TD1 , is brought over as 0.57 DI.

instead of 0.057 psi, thus causing a very significant term. Instead of 0.578 psi for DI, the term becomes

0. 1065 psi. This could fix the problems for this calculation.

19 K. Melson EXCEL Section 7.10: The highest operating 8/10/12 STA section revised.

Services Corp. drywell pressure at which the trip is required is shown to be 2 psig, from E100.0; however, this is in excess of the trip setpoint; and thus the STA doesn't make sense as is. A better starting point could come from the LCO limit for containment pressure during normal operation. This would be LCO 3.6.1.4, which limits containment pressure to I psid containment to auxiliary bldg pressure. The listings I see for Aux Building pressures are very close to 0 psig within E100.O. Thus, I would say that starting somewhere around I psig is closer to a more realistic starting point than 2 psig. We can also credit operating experience to say we are ok. I think it also passes the STA, if non-accident errors only are used with this limit.
