Question:

The NRC Staff has a question on the safety status of the setpoints for cooling tower fan speed control and cooling tower bypass valve automatic closure. The licensee has credited manual operator actions for these functions. If it is determined that these items are safety-related, the Staff requests the calculations for each setpoint; a statement of whether each is, or is not, a limiting safety system setting (LSSS), and a TSTF -493 statement.

Response

This question has multiple parts which will be addressed in order.

There are three credited operator actions in the LDCN 12-0015 license amendment request (LAR) which have defined completion times as discussed on pages 14-15 of the LAR

Enclosure:

1. Verification of proper UHS Cooling Tower operation and securing affected ESW train within 70 minutes of the accident.
2. UHS Cooling Tower Inlet temperature switchover within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> to ESW Pump Discharge temperature.
3. Securing one train of ESW within 7 days.

Actions 2 and 3 are time-driven and do not rely on indication inputs for progression through the applicable Emergency Operating Procedures (EOPs). (See LAR Enclosure pages 14-16 and item 8 (pages 6-7) ofLAR Attachment 6.)

Action 1 requires the isolation of an ESW train within 70 minutes if a failed system component is discovered, as discussed in detail on LAR Enclosure pages 15 and 16. The credited operator action requires the use of the following indications in EOP E-1 step 11:

Step 11.a-Annunciators 30E [NG07 bus undervoltage I overvoltage annunciator] and 31 E [NG08 bus undervoltage I overvoltage annunciator]: Check NG07 [ 480 V AC load center, train 'A' separation group 1] and NG08 [480 VAC load center, train 'B' separation group 4] bus trouble annunciators (non-safety related);

Step 11. b - Computer points EFT0067 A [UHS cooling tower inlet temperature from ESW train 'A'] or EFT0068A [UHS cooling tower inlet temperature from ESW train 'B']

Determine ESW return temperature (UHS cooling tower inlet temperature) (non-safety related);

Step 11.b Response Not Obtained (RNO) If computer points are unavailable, determine UHS cooling tower inlet temperature using High/Low ESW return temperature indications EFTSHL0067B, EFTSHL0068B (non-safety related);

Page 1 of3

Step 11.c-EFHIS0065A and 66A [UHS cooling tower bypass valve hand indicating switches for ESW trains 'A' and 'B' respectively] on control room panel RL019 or locally at EFHV0065 and 66: Check UHS cooling tower bypass valve position indication is appropriate for the temperatures determined in step 11.b (These valve "HIS" hand-indicating switches are safety-related, but are similar to the devices excluded from the scope ofTSTF-493-A Revision 4, i.e., devices that derive input from contacts which have no associated sensor or adjustable device.)

Step 11.d - EFHIS0061 A & 62A [UHS cooling tower fans hand indicating switches for ESW trains 'A' and 'B' respectively] on control room panel RL019 or locally at EFHIS0063A/B/C/D, EFHIS0064A/B/C/D [local UHS cooling tower fans hand indicating switches for ESW trains 'A' and 'B' respectively]: Check UHS cooling tower fan speed indication is appropriate for the temperatures determined in step 11. b (These fan "HIS" hand-indicating switches are safety-related, but are excluded from the scope of TSTF-493-A Revision 4.)

If the indications in the RNO column are unavailable, E-1 directs a transfer to EOP Addendum 17 to secure the ESW train in which a failure is suspected. Verification of successful ESW train isolation can be achieved using the ESW pump running indications found on safety-related hand indication switches EFHIS0055A and EFHIS0056A on control room panel RL019.

The ESW pump hand-indicating switches are safety-related, but are excluded from the scope of TSTF-493-A Revision 4. LAR Attachment 6 (pages 8-11) provides detailed discussions ofEOP device pedigree. As such, there are no TSTF-493-A implications associated with cues for the above operator actions.

As discussed in detail on LAR Enclosure pages 15-17, step 19 ofEOP E-1 directs the performance ofEOP Addendum 40 to transfer the automatic control of the UHS cooling tower bypass valves and fans to the ESW pump discharge temperature channels (EFT-0061 and EFT-0062). Although not a credited operator action with a defined completion time (LAR Enclosure page 15), Step 5 ofEOP Addendum 40 is a continuous action step to check UHS cooling tower fan speeds (safety-related EFHIS0061A & 62A discussed above under E-1 Step 1l.d) vs. the ESW pump discharge (ESW supply) temperature (safety-related temperature indicators EFTI0061, EFTI0062) so that any equipment failures involving the temperature control handswitches (EFHS0067, EFHS0068) or ESW supply temperature loops (EFT-0061, EFT-0062) would be recognized and addressed (e.g., by securing the affected ESW train, if necessary) to support maintaining the necessary UHS pond inventory.

There is one setpoint calculation associated with the safety-related, temperature-based circuitry used to automatically position the EFHV0065/0066 UHS cooling tower return bypass valves and to automatically establish the speed of UHS cooling tower fans. That setpoint calculation is included as Attachment 2 and demonstrates that a 2.5°F Channel Uncertainty must be accounted for when establishing the Nominal Trip Setpoints that protect the Safety Analysis Limits defined in Calculation EF -123 (LAR Enclosure pages 8-12). E-1 step 11 (discussed above) verifies the proper operation of the bypass valves and cooling tower fans from the EFT -0067 A and EFT-0068A channels. E-1 step 19 (manual enabling of automatic control from ESW pump Page 2 of3

discharge temperature loops at 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />) directs the performance of EOP Addendum 40 which verifies proper operation of the bypass valves and cooling tower fans from the EFT -0061 and EFT -0062 channels. However, none of the setpoints in the EFT -0067 A, EFT -0068A, EFT -0061, or EFT -0062 temperature channels satisfy the definition of a Safety Limit-Limiting Safety System Setting (SL-LSSS) as agreed to between the NRC Staff and the industry during the review and approval ofTSTF-493-A Revision 4.

During the NRC review ofTSTF-493 the Staff posted a comment on March 22, 2006 that stated:

"TSTF-493, Revision 0 did not generically define the scope of the instrumentation affected. To cover those systems that should be covered to meet 10 CFR 50.36 the TSTF scope for identifying LSSS should apply to TSs instrumentation related to variables which protect the integrity of the reactor fuel and the integrity of the reactor coolant pressure boundary (RCPB) physical barriers. This translates to TSs instrumentation, excluding manual trip functions, that trip the reactor (i.e.,

reactor trip system instrumentation, reactor protection system instrumentation);

TSs instrumentation that ensure the core is adequately cooled in the event of a design basis accident or transient (i.e., engineered safety feature actuation instrumentation, emergency core cooling system instrumentation); TSs instrumentation that provides additional margin to core safety limits, such as the end-of-cycle recirculation pump trip instrumentation [for BWR plants]; and TSs instrumentation that provides RCPB overpressure protection (pressurizer safety valves, safety/relief valves)."

In response to this comment the Owners Groups had the NSSS vendors identify a list of generic LSSSs that protected the reactor core and reactor coolant pressure boundary pressure Safety Limits during anticipated operational occurrences, which are the only events that are considered for determining the Safety Limit (SL) LSSSs. TSTF-493 was subsequently revised to include the identified list of LSSS functions for each NUREG.

Additional supporting or exempting statements were also included to further define the components that must be considered in the LSSS scope. For Westinghouse plants, the SL-LSSS functions that are within the scope of additional, setpoint-related surveillance and operability footnotes are limited to the functions specified in TS 3.3.1, "RTS Instrumentation," and TS 3.3.2, "ESFAS Instrumentation," as discussed in TSTF-493-A, Revision 4, Attachment A, "Identification of Functions to be Annotated with the TSTF-493 Footnotes-NUREG-1431, Westinghouse Plants." TSTF-493 does not apply to the LDCN 12-0015 LAR since no SL-LSSSs are involved.

1.0 Purpose & Scope Calculation J-UEF03, Rev. 001 Page 2 of21 This calculation determines the UHS Cooling Tower fan speed control and ESW to UHS Cooling Tower bypass valve control setpoints considering instrument uncertainties.

Post Implementation of Calculation EF -123 Temperature loops EFT-0061/62 (ESW supply line) and EFT-0067A/68A (ESW return line) actuate the UHS Cooling Tower fans (CEF01A/B/C/D); first in slow speed then into high speed as the temperature rises. The fans are normally controlled via the return line and switched to the supply line post Design Basis Accident (DBA) initiation. Fan control is used to protect two design basis parameters. In the initial hours of a DBA these loops protect the maximum UHS temperature limit (FSAR SP Chapter 9.2, Calc. EF-123).

The fans are then used to ensure an adequate UHS inventory is maintained throughout the UHS's 30 day action statement (FSAR SA Chapter 9.2, Calc. EF-123).

These temperature loops also actuate the ESW to UHS Cooling Tower bypass valves (EFHV0065/66). Bypass valve control is set up to ensure freeze protection (FSAR SA Chapter 9.2, RFR 200802059). This valve also aids the above mentioned fan operation in that cooling is only achieved when the valve is closed, allowing return water over the UHS Cooling Tower fill.

Configuration A below details temperature instrumentation loops EFT -0061/62 (ESW supply line) and EFT-0067A/68A (ESW return line) for UHS Cooling Tower fan and bypass valve control.

Each output isolation card feeds a selector switch (no signal impact/uncertainty) to allow selection between the supply and return lines. (EFT -0067 A to EFT-0061 & EFT-0068A to EFT-0062)

Post Implementation of MP 11-0004, Pre Implementation of Calculation EF -123 MP 11-0004 is incorporating physical SSC changes to allow the plant operational changes shown above per the requirements of EF -123 once they have been approved by the NRC. Until NRC approval of the EF-123 changes, MP 11-0004 will approve the physical SSC changes against the existing UHS design basis documentation, specifically calculation EF-54. Per EF-54 and FSAR SA 9.2.5.2.3 & FSAR SA 9.2.5.5 the current design basis function of these setpoints is freeze protection only. As the EF-123 changes also review the instrumentation setpoints with respect to freeze protection, the analysis of setpoints for the "Post Implementation of Calculation EF -123" used in the remaining sections of this calculation is bounding over the interim state of operation post MP 11-0004 implementation. No further review for this is necessary or will be performed.

SYSTEM EF LOOPS 67A & 68A DETERMINE THE DEGREE OF UNCERTAINTY IN THE SUBJECT INSTRUMENTATION LOOPS-This calculation is identical to J-UEF03, Revision 000. It shows one revision performed prior to the creation of J-UEF03, but is otherwise identical. The 'I' in the title implies a link to the Wolf Creek Power Plant, but there is no UHS at Wolf Creek. J-UEF03, Revision 001 has superseded J-UEF03, Revision 000; it has also superseded J-1EF03, Revision 000.

This calculation determined the setpoints when they were controlled via EF Loops EFT -0067 A and EFT-0068A exclusively. This document was superseded by J-UEF03, Revision 001.

Calculation J-UEF03, Rev. 001 Page 5 of21 1.1.4 J-UEF03, Revision 001, Instrument Loop Uncertainty Estimate: UHS Cooling Tower Fan Speed and Bypass Valve Control - This revision incorporates the changes done by MP 11-0004 to the UHS Cooling Tower Fan Speed and Bypass Valve Control. The MP added a hand switch to allow control off of the existing ESW return line temperature instrumentation loops EFT -0067 A and EFT -0068A or the new ES W supply line temperature instrumentation loops EFT -0061 and EFT -0062.

2.0 Methodology 2.1 The methodology used to determine this uncertainty will be that of ISA-S67.04, Dated September 1994, Setpoints for Nuclear Safety-Related Instrumentation, and ISA-RP67.04, Dated September 1994, Methodologies for the Determination of Setpoints for Nuclear Safety-Related Instrumentation.

2.2 The general equation for channel uncertainty (CU) is:

2 2

2 ] 1/2 IRB I CU = [PM + PE + e 1 + e 2 +... + e N

+ BT +

T

Where, PM = Random component of the process measurement uncertainty PE = Random component of the primary element uncertainty en= Square Root Sum of the Squares of all random independent components of uncertainty associated with a module n BT = Algebraic sum of all bias estimates for all biases in a channel (2.2)

RBT =Sum of the absolute value of all random bias (and arbitrary distribution) estimates in a channel.

2.3 The general equation for a module uncertainty (en from equation 2.2) is:

e= [RA2 + DR2 + TE2 + RE2 + SE2 + HE2 + SP2 + MTE2]

112 + B+ IRBI (2.3)

Where, e = Module total uncertainty RA = Module reference accuracy DR = Module drift over a specified period TE = Module temperature effect RE = Module radiation effect SE =Module seismic (vibration) effect HE = Module humidity effect SP = Module static pressure effect MTE = Maintenance and test equipment used during module calibration B =Bias uncertainty estimates associated with module RB = Sum of absolute values of all random biases or abnormally distributed uncertainties for the module.

2.4 Bounding Uncertainty Loop Calculation J-UEF03, Rev. 001 Page 6 of21 Configuration A, in section 1.0 above, shows all of the loop components necessary to actuate the UHS Cooling Tower fans and by-pass valves. This section breaks down Configuration A into a bounding set of loop modules that shows the loop uncertainty for any one component actuation.

The 2AO-L2C-R circuit cards have no impact on signal transmission. These cards are used for isolation and interlocking. For this reason they have been removed from the uncertainty. The supply/return line loop selector hand switch will also not be included as it also has no impact on signal transmission. The three Low, High, and High-High setpoint bistable (switch) circuit cards are identical and for any one component actuation only one switch will be used. Thus for any one component actuation the signal is impacted by the three modules shown below.

The bounding uncertainty case is as follows:

Calculation J-UEF03, Rev. 001 Page 7 of21 2.5 Dependent uncertainties, shared amongst the separate modules, will be combined in such a way that independent variables will be combined using a square root sum of the square technique, (SRSS) while dependent variables will be combined by algebraic addition.

Reference 8.3.2 describes how the dependence of the various effects is related. The variables described in section 2.3 are compared in Table 3, Variable Dependency, for each component in the loop.

a: The reference accuracy, or calibrated accuracy, and the module drift are both dependent with respect to M&TE and independent with respect to each other.

This does not include the TE as it is not calibrated.

b: Since these components are all located in the same cabinet, they are all exposed to the same environment and seismic effect.

Thus, the temperature, humidity, and seismic effects will be considered dependent between modules (circuit cards), but independent with respect to each other.

c: Since these components all use the same power supply, the power supply effects will be considered dependent.

i:

This effect is considered independent of all other effects.

Calculation J-UEF03, Rev. 001 Page 8 of21

  • Since all of the components are exposed to no more than atmospheric pressure and minimal radiation, the only environmental effects are temperature and humidity.
    • Only one piece of M&TE will be considered for all of the rack mounted components.

2.6 Final Setpoint Determination The final step in this calculation is to determine the setpoints for UHS Cooling Tower Fan and Bypass Valve control. Each setpoint is determined by combining the Safety Analysis Limits (SALs) found in the Design Inputs section, the setpoint uncertainties derived in this calculation, and margin.

The formula for a rising setpoint:

TS = SAL - CU - Margin The formula for a falling setpoint:

TS = SAL + CU + Margin

Where, TS = Trip Setpoint SAL = Safety Analysis Limit CU = Channel Uncertainty 3.0 Assumptions 3.1 Assumptions concerning the values of specific error terms for the loop components are included within the "Design Inputs" section for that component.

The Process Measurement Accuracy is an error that is introduced due to possible fluctuations in the process medium that will impact the temperature measurement.

Per calculation J-2B01, environmental effects are not considered. The temperature linearity is included in the basic accuracy. The humidity is assumed to have no effect as the RTD's are sealed devices that are also protected by a closed thermo-well and 0-ring sealed connection head assembly. No Process Measurement Accuracy will be incorporated for this loop.

4.3.1 Frequency of Element Accuracy Confirmation: Every 6 Months per MP 11-0004.

4.3.2 No uncertainty will be given to the temperature elements for temperature, radiation, and humidity. FSAR 3.11(8).5.7 describes a mild environment as being,:SilO OF,< 103 rads, and,:S 90% humidity while FSAR Table 3.11(8) shows this room reaching 120 OF and 95% humidity. However, this section also describes a mild environment as an environment that will not exceed its anticipated abnormal condition.

NUREG0588 implementation has further determined the temperature elements to be rated category 'D' for HEL8, LOCA, and MSL8 design basis accidents (Ref. Director Database). Category D is defined as being located in a mild environment post-accident. Temperature and humidity uncertainties are not necessary for equipment rated for mild environments. The expected radiation levels are within mild environment requirements.

4.3.2.1 Temperature Effect: This component will not be impacted by temperature shifts as its primary function is to measure temperature. Per Table 5, Expected Environment A Values, the element could see a temperature shift of 16°F (120-104oF) which is inside the temperature elements expected range. Per calculation J-2801, the normal environmental temperature effect for this component is included in the Reference Accuracy (RA).

4.3.2.2 Humidity Effect:

Per calculation J-2801, this component will not be impacted by humidity changes as the RTD' s are sealed devices that are protected by a closed Thermo-well and 0-ring sealed connection head assembly.

4.6 Maintenance & Testing Equipment (MTE)

Typically a 1 to 1 accuracy (MTE to Component) is used for calculating MTE uncertainties. I&C craft is then held to a 2 to 1 accuracy for calibration. This is done for conservatism in setpoint uncertainty calculations. However, calculation EF-123, which determines the safety analysis limits (SALs) for these setpoints requires all conservatisms to be removed. In order to remove conservatism, the actual MTE accuracies will be used for this calculation.

The temperature element is not calibrated. The temperature curves are determined at the factory and provided to Callaway for scaling.

Calculation J-UEF03, Rev. 001 Page 14 of21 The rack components (TT, TS) are calibrated using a decade box (RTD simulator) and Digital Multimeter (DMM). The DMM used to calibrate these loops must be a Keithley I97 or equivalent. Per reference 8.2.I 0, the uncertainty of this DMM is 0.03% span (I 00 OF per 4.4.I) or 0.03 °F. The decade box used to calibrate these loops must be a Transcat 70 I OT decade box or equivalent. Per reference 8.2.I 0 the uncertainty of the decade box is 0.02% of the reading. The worst case reading (the highest possible ohms reading) is I2I.I50 per reference 8.2.I, giving an uncertainty of 0.02423!2. Converting to degrees xo~ =

0 02423n (Ref 4.2.3.I, 4.2.3.2) determines a decade box uncertainty ofO.II25°F.

4. 7 Safety Analysis Limits (SAL)
4. 7.I Freeze Protection The ESW to UHS Cooling Tower Bypass Valves open on a low temperature to prevent water going over the cooling tower fill and freezing. In addition, when the initial DBA temperature is below freezing, the water, although rising in temperature, cannot be allowed over the fill until a certain point to ensure large droplets don't freeze and impede tower performance.

Per RFR 200802059, the criteria for closing EFHV0065/66 requires either the ambient wet-bulb temperature to be greater than 32 For the ESW return water temperature to be greater than or equal to 6I F. The fans may then be run at any temperature above this to provide cooling. The freeze protection function is necessary for both supply and return line setpoints. The Bypass valve fulfills a secondary role as being necessary for fan operation.

4.7.1.I Freeze Protection SAL-6I F.

(RFR 200802059) 4.7.2 Return Line SALs The UHS Cooling Tower Fan Speed and Bypass Valve Position is controlled off of the return line at the beginning of a DBA to protect the ESW system from reaching the max ESW temperature of 92.3 F (Ref. 8.2.4, 8.I.4) A discussion of the GOTHIC model anticipated max temperature and its acceptability can be found in Calculation EF -123 (Ref 8.I.4 ). With respect to setpoint determination the GOTHIC model requires the UHS Cooling Tower Fast Speed control (high-high setpoint) to actuate (set) between I 02.5 and 107.5 F. The fast speed (high-high setpoint) reset values are of no consequence as the temperature is not anticipated to reach this limit prior to swap over to the supply line temperature loops. The slow speed (high setpoint) fan runs in this scenario are negligible as the temperature in the return line heats up quickly and doesn't reach normal levels until after swap over to the supply line. The bypass valve must be closed prior to reaching the fast speed setpoint to allow for proper cooling.

4.7.2.1 Fan Fast Speed Set-Between I02.5 and 107.5 OF (Calculation EF -123)

4.7.3 Supply Line SALs Calculation J-UEF03, Rev. 001 Page 15 of21 After the ESW DBA temperature has reached a controllable state the UHS Cooling Tower Fan Speed and Bypass Valve Position will be controlled via the supply line temperature. At this point max temperature and UHS inventory is a concern for UHS operation. The GOTHIC model anticipated temperature values, as well as the inventory losses associated with using these setpoints are determined and can be found in calculation EF-123. With respect to setpoint determination the GOTHIC model fast and slow (high-high and high setpoints) set and reset values are used to ensure these two limits are maintained. The bypass valve is not expected to change state during the use of this control, but it must be closed to achieve proper cooling from the tower.

Calculation J-UEF03, Rev. 001 Page 16 of21 5.1 The final equation for the Channel Uncertainty combines equation 2.2 and 2.3 for use with the values found in Table 11. Dependant variables between modules from table 4 are taken out of their module specific uncertainty and combined in the overall channel uncertainty. The resultant Channel Uncertainty Equation is calculated below:

(0.15+ 0.15i] 112 cu = 2.475 OF The Setpoint Uncertainty associated with temperature instrumentation loops EFT -0067 A, EFT-0068A, EFT-0061, and EFT-0062 is 2.475 °F. For ease of use and to add margin, the setpoint uncertainty (Channel Uncertainty CU) used in this calculation will be rounded up to 2.5 OF.

5.3 Setpoint Determination Per the methodology for deriving a Trip Setpoint (TS), found in section 2.6, TS is equal to the Safety Analysis Limit (SAL) +/- the Channel Uncertainty (CU) +/- Margin (M).

The values are added or subtracted depending on whether the SAL is triggered rising or falling (directionality). The setpoints found in Tables 12 and 13 have been derived using this equation.

5.3.1 Example Calculation (Tables 12113): Supply Line TSHH Set (Fan Fast speed actuation)

Required action point: 102.5-107.5.

Calculation Methodology (2.6): Rising: TS = SAL - CU -Margin Calculation Methodology (2.6): Falling: TS = SAL+ CU +Margin If TS is known, margin is then: Rising: Margin = SAL - CU - TS IfTS is known, margin is then: Falling: Margin= SAL- (CU + TS)

      • Setpoint supports a Safety Analysis Limit (SAL). Other setpoints may be changed without impacting the analysis (EF-123).

Note 1: The values chosen for non-SAL setpoints support the values used in calculation EF-123. As their function does not impact the safety analysis results, they may be revised without recourse to the safety analysis. Thus the margin associated with these setpoints is not considered. These setpoints do operate in the proper order. With raising temperature the valve closes followed by the slow start of the fans and finishing with the fast start of the fans. With falling temperature when the fast fans kick off the slow fans will be running. The slow fans will then kick off followed by the valve opening. It is important to note that there is an interlock to ensure the fast fans will run if a set signal has been provided to the slow and fan start circuitry.

Note 2: The valve must be closed prior to the fast speed start signal to ensure the safety analysis is maintained. However, the valve should be closed prior to the slow speed start for proper cooling tower operation. For this reason the slow speed start setpoint was used to determine valve reset margin.

7.0 Conclusion Calculation J-UEF03, Rev. 001 Page 19 of21 This calculation determines the UHS Cooling Tower fan speed control and ESW to UHS Cooling Tower bypass valve control setpoints considering instrument uncertainties. A Channel Uncertainty for instrumentation temperature loops EFT -0061, EFT -0062, EFT-0067 A, and EFT -0068A of 2.5 OF has been determined via this calculation. The UHS Fan slow and fast speed control setpoints, as well as the UHS bypass valve control setpoints have additionally been determined. See Table 12, Supply Line (EFT-0067A, EFT -0068A) Setpoint Determination, and Table 13, Return Line (EFT -0061, EFT -0062)

Setpoint Determination, for a breakdown of the new values.

7.1 Margin Discussion The margin associated with each setpoint is discussed in Table 12, Supply Line (EFT-0067A, EFT-0068A) Setpoint Determination, and Table 13, Return Line (EFT-0061, EFT-0062) Setpoint Determination.

Per section 5.2, the Channel Uncertainty was rounded up to 2.5 OF, providing a relatively small amount of margin in the setpoint determination section.

Per section 4.3.3, the seismic effect was rounded to 1 oF, providing a relatively small amount of margin to the temperature element uncertainty determination. Section 4.3.3 also discusses inherent margin associated with the testing of this equipment.
