The first level of protection is from the loss of voltage relays which operate on a definite time delay. The second level of protection is from the degraded voltage relays which operate on an inverse time characteristic.

3.2.4 Tolerance for the as-found operate time for a 120 volt to 92 volt step change shall be _>30 seconds and <50 seconds. These values fall within the minimum analytic limit of 20 seconds and the maximum analytical limit of 136.8 seconds.

3.2.5 Tolerance for the~as-found operate time for a 120 volt to 104.1 volt step change shall be

r 3.2.6 The relay shall be calibrated for an as-left operate voltage of >105.2 volts and <105.7 volts (nominal 105.2 volts, +0.5 volts, -0.0 volts).. This is based on the decision to create a negative calibration bias.

3.2.7 The relay shall be calibrated for an as-left operate voltage time delay of >89.5 seconds and <94.1 seconds (91.8 seconds, +/-2.3 seconds) for a 120 volt to 105.2 volt step change.

This range is based on the decision to limit calibration uncertainty to +/-2.5% of the nominal setpoint (91.8 seconds).

3.2.8 The relay shall be post-calibration trip tested for a 120 volt to 92 volt step change for an as-left tolerance of >30 seconds and <50 seconds. These values fall within the minimum analytic limit of 20 seconds and the maximum analytical limit of 136.8 seconds.

3.2.9 The relay shall be post-calibration trip tested for a 120 volt to 104.1 volt step change for an as-left tolerance of >82 seconds and -<101.6 seconds. These values are based on the nominal setting at 105.2 volts of 91.8 seconds +/-9.8 seconds (nominal +/- channel calibration acceptance value).

DA-EE-93-006-08 Page 8 of 49 Revision 5

3.3.1 The as-found operate voltage shall have acceptance criteria of >105.0 volts and <105.9 which are the minimum and maximum calculated setpoints.

3.3.2 The as-found reset voltage shall have acceptance criteria of ý>105.0 volts and <106.4 volts. The minimum value of 105.0 volts is equivalent to the minimum calculated setpoint for the operate voltage and the value of 106.4 volts is 0.5% higher than the maximum calculated setpoint.

3.3.3 The relay shall be trip tested for a 120 volt to 92 volt step change with acceptance criteria of >:30 seconds and <50 seconds. These values conservatively fall within the minimum analytic limit 6f 20 seconds and the maximum analytical limit of 136.8 seconds.

3.3.4 The relay shall be trip tested for a 120 volt to 104.1 volt step change with acceptance criteria of ?68.1 seconds and <125 seconds. The test voltage is 1.1 volts below the nominal setpoint of 105.2 (nominal - CCA). This range is conservatively based on the minimum calculated setpoint of 68.1 seconds at 105.0 volts and the maximum calculated setpoint of 125 seconds.

3.4 Loss of Voltage Relay Calibration The loss of voltage relays shall be calibrated at a nominal setpoint of 93.2 volts (dropout voltage) and 2.4 seconds which fall within the Calculated Setpoint Region (as seen on the chart in section 13.3).

3.4.4 Tolerance for as-found dropout time shall be +/-0.06 seconds from the previous as-left tolerance. This is based on the channel calibration acceptance value of 0.06 seconds.

3.4.5 The relay shall be calibrated for an as-left dropout voltage of >93.2 volts and <93.7 volts (nominal 93.2, +0.5 volts, -0.0 volts). This is based on the decision to create a negative calibration bias.

3.4.6 The relay shall be calibrated for an as-left dropout voltage time'delay of >2.13 seconds and <2.62 seconds (2.4 seconds, +0.22 seconds, -0.27 seconds). The range is based on the minimum calculated setpoint of 2.13 seconds and the maximum calculated setpoint of 2.62 second*.

DA-EE-93-006-08 Page 9 of 49 Revision 5

3.4.7 The relay shall be calibrated for an as-left pickup voltage of >93.7 volts and <94.2 volts.

These values are 0.5 volts higher than calibration values for the dropout voltage.

3.5.2 The as-found pickup voltage shall have acceptance criteria of >93.0 volts and <94.6 volts. The minimum value of 93.0 volts is equivalent to the minimum calculated setpoint for dropout voltage and the value of 94.6 volts is based on the stated tolerance of dropout being 99% of pickup.

3.5.3 The relay shall be trip tested for a 120 volt to 0.0 volt step change with acceptance criteria of >2.13 seconds and <2.62 seconds. This range is based on the minimum calculated setpoint of 2.13 seconds and the maximum calculated setpoint of 2.62 seconds.

3.5.4 The relay shall be trip tested for a 120 volt to 92.5 volt step change with acceptance criteria of >2.13 seconds and <2.62 seconds.

This range is based on the minimum calculated setpoint of 2.13 seconds and the maximum calculated setpoint of 2.62 seconds.

4.0 Design Inputs 4.1 EP-3-S-0505 revision 2, Instrument SetpointlLoop Accuracy Calculation Methodology 5.0 Assumptions 5.1 VTD-A0500-4002 provides the time-voltage characteristic curves for the inverse time degraded voltage relays which are Type 27 manufactured by ABB. Per the relay setting schedules (11253-1 sheets 3 and 4) the relays are set at 105.2 volts with a TLS setting of 6. 2 of design analysis DA-EE 068-03, Offsite Power Load Flow Study derives the equation for the curve matching the vendor manual time-voltage curve for TLS setting 6. The formula for the curve was determined to be matched by the equation V =

(VsM-rINN)(1-e(008(1 3. 5-T))), where T is time and the value to be inserted for VsErWING is the operate or reset coefficient. The derived equation is utilized in this calculation to demonstrate the proper application of the time delay relay for both operate and reset values as well as its coordination for protection of electrical equipment. VTD-AO500-4002 also indicates that the relays are set by adjusting the operate setting. The curves for reset are fixed at a value 0.5% higher than the associated operate value.

5.2 VTD-A0500-4002 indicates there is a 0.5 volt variation in operating voltage over the temperature range 20TC to 40TC for the degraded voltage relays. The relays are installed in DA-EE-93-006-08 Page 10 of 49 Revision 5

locations where ambient temperature varies between 10°C and 40TC. It is assumed that the variation is linear and can be interpolated over the expanded range to account for the actual environmental conditions.

5.3 VTD-A0500-4002 indicates there is a 0.2 volt variation in operating voltage for a 10 volt variation in control voltage. The relays are subjected to a larger variation in control voltage, between 128 volts and 140 volts. It is assumed that the variation is linear and can be interpolated over the expanded range to account for the actual control voltage applied to the relays.

5.4 Gilbert Associates Specification SP-5201 revision 3 indicates motors specified for safeguards equipment were required to be designed and satisfactory for full voltage starting at 80% rated voltage. It assumed that the motors are capable of running continuously at 90%

rated voltage (per NEMA Standard MG-1 Motors and Generators - induction motor variation from rated voltage).,

5.5 Thermal capability curves for all equipment connected to the 480 volt safeguards busses is not contained in Ginna's design basis document collection. The guidance of ANSI Standard C50.41, which provides criteria for the momentary operation of motors, is assumed to be applicable for utilization in the coordination curves being created in this calculation. The exceptions identified in the standard for which it can not be applied have been reviewed and are not applicable to the equipment connected to Ginna's 480 volt safeguards busses. In addition, due to the large amount of margin which the curve indicates is available, it is assumed that any additional voltage drop from the bus to the terminals of driven equipment will have a negligible effect on the results of this calculation. The thermal capability curves for 440, 460 and 480 volt motors have been added to the coordination curve in section 13.

The actual slope of the thermal capability curves follow an exponential function, however they have been depicted as straight lines for the small voltage range at which they are plotted. This approximation will have a negligible impact on the ability to demonstrate coordination for equipment protection.

5.6 VTD-A0500-4201 states in the "Specifications" section under "Tolerances" that repeatability over the allowable DC control power range is +/- 0.1%. The VTD also identifies in the "Specifications" section under "Control Power" that the allowable variation for the 125 VDC relays is 100 to 140 volts. It is assumed that variarion is linear and can be interpolated over the actual range of 128 to 140 volts for the Ginna installation.

5.7 DA-EE-92-131-06 calculates the degraded voltages for AC motor operated valves (MOV's).

The analysis demonstrates the operability of MOV's at bus voltages of 368 volts and 414 volts. It is assumed that these loads do not require discussion in this calculation (DA-EE 006-08) since DA-EE-92-131-06 provides the basis for their operability. The analyses are cross referenced in the configuration management system.to ensure reviews are performed when revisions are made.

5.8 DA-EE-92-008-07 analyzed the effect of degraded voltages on safety related motor control center (MCC) loads. The analysis demonstrates the operability of loads fed from the MCC's at a bus voltage of 414 volts. It is assumed that these loads do not require discussion in this DA-EE-93-006-08 Page 11 of 49 Revision 5

calculation (DA-EE-93-006-08) since DA-EE-92-008-07 provides the basis for their operability. The analyses are cross referenced in the configuration management system to ensure reviews are performed when revisions are made.

5.9 2 of the Offsite Power Load Flow Study (DA-EE-96-068) calculates the response of the circuit 767 tap changer for the limiting load flow case 116L_2007_AB. The most limiting response is identified as the target profile in attachment 12 of DA-EE-96-068 and is recreated in the coordination curve in this calculation for comparison of coordination with the degraded voltage relays.

5.10 The loss of voltage relays are set by adjusting the pickup setting. The dropout setting is a fixed percentage of pickup based on tap settings available on the relays. Ginna utilizes the 99% tap and calibrates the relays at the desired dropout voltage.

5.11 The meter drift for the KA-241 voltmeters is assumed to be 1.0% for a 72 month frequency.

There is no vendor data available for drift. Indicator drift over a 72 month calibration cycle is assumed to be equal to the reference accuracy of the voltmeter, which is specified in VTD-WO120-4470 to be 1.0% full scale.

5.12 There is no vendor data available for Parallax for calculating voltmeter uncertainty. Parallax is assumed to be negligible because of the Westinghouse "full view" voltmeter design. The voltmeter dial scale is beveled so that there is no dial shadow, making it possible to read the voltmeter at angles up to 60 degrees.

5.13 The effects of repeatability, hysteresis and linearity are assumed negligible in the total loop uncertainty calculation for the voltmeters. There is no vendor data available for repeatability, hysteresis and linearity. The calibration of the voltmeter is currently performed in both directions, as seen on calibration procedures CP-501.3, CP-501.4, CP-501.5 and CP-501.6.

This ensures that the attributes of reference accuracy (repeatability, hysteresis and linearity) are accounted for. In addition, generic data about taut band suspensions from another vender (Weschler Instruments) indicates that the taut-band suspension in type K-241 instruments eliminates friction, giving better accuracy [than the conventional pivot and jewel types] and almost perfect repeatability.

8.0 Method of Analysis Instrument uncertainties will be determined and relay setpoints will be evaluated using the methodology of procedure EP-3-S-0505 except where indicated otherwise. This procedure utilizes guidance from ANSI/ISA-S67.04-1994 which is endorsed by ISA-$67.04-1994. EP-3-S-0505 states that it does not apply to time delay relays and protective devices, however NRC IN 91-29 states that the guidance in ANSI/ISA-S67.04-1982 was endorsed by regulatory Guide 1.105 revision 2 and applies both to process instrumentation and in part to certain relays that perform a safety function.

DA-EE-93-006-08 Page 14 of 49 Revision 5

9.0 Acceptance Criteria Requirement Acceptance Criteria UFSAR Section 7.3.3.2 states "The loss of voltage and degraded voltage trips ensure operability of engineered safety features equipment during a postulated design-basis event concurrent with a degraded bus voltage condition. The undervoltage setpoints are selected so that engineered safety features motors will start and accelerate the driven loads (pumps) within the required time and will be able to perform for long periods of time at degraded conditions above the trip setpoints without significant loss of design life."

Acceptance Criteria #1 Engineered safety features motors will start and accelerate the driven loads within the required time without the undervoltage voltage relays actuating.

Acceptance Criteria #2 Degraded voltage relays shall be set to allow operation of connected loads at degraded voltages (above the equipment ratings) and actuate at a degraded voltage (below equipment ratings) to ensure equipment thermal damage does not occur due to the degraded voltage condition.

UFSAR Section 8.3.1.1.4.2 states "Each safeguards bus has two undervoltage channels. Each channel has a type 27N relay to detect a complete loss of voltage and a type 27 relay to detect abnormally low voltage. One out of two relays is required to activate the channel.

10.0 Calculations/Computations - Degraded Voltage Relays (Type 27) 10.1 Degraded Voltage Relay Operate Voltage Setpoints 10.1.1 Minimum Analytical Limit (ALMIN)

Engineered safeguards sequence motors on Ginna's 480 volt Class 1E busses are rated 440 and 460 volts. They are designed for 80% degraded voltage starting and 90%

degraded voltage continuous operation [see assumption 5.4]. Utilizing the 90% rating for continuous operation, the 440 volt motors can operate continuously at 396 volts and the 460 volt motors can operate continuously at 414 volts.

The minimum analytical limit for the 480 volt Class 1E bus degraded voltage protection is 414 volts. This value is based on the NRC Safety Evaluation Report dated 3/26/1981 for Amendment No. 38 to Provisional Operating License which approved the degraded voltage relay setpoint of greater than or equal to 414 volts. Transposing this value through the 480/120 volt bus PT produces a voltage of 103.5 volts. This is the minimum voltage at which the degraded voltage relay is expected to begin timing during a degraded voltage condition. The degraded voltage relays will begin timing for all voltages below the minimum analytical limit.

A bus voltage of 414 volts would result in a slightly lower voltage at the terminals of the motors due to the voltage drop in the motor feeder cables. Since motors are constant power devices, operation at voltages below the continuous rating will result in an increased current requirement to the motor resulting in additional thermal heating. Long term operation at elevated current levels will result in accelerated aging of the insulation system of the motor windings. For the purpose of operating the emergency safeguards sequence loads, including smaller loads fed from motor control centers, this loss of life is considered negligible since the operating time at this voltage is minor in comparison to the overall lifespan of the equipment.

If the degraded voltage relays failed to actuate at 414 volts on the bus, there are procedural actions which will ensure equipment is protected from extended operation at low voltage. Procedure AP-ELEC.2 provides guidance for Operators to responding to low voltages on the 480 volt safeguards busses. Operations is required to start both emergency diesel generators if any 480 volt safeguards bus voltage lowers to less than 420 volts. If bus voltage drops below 414 volts, Operations is required to transfer the safeguards busses to the emergency diesel generators. [NOTE: see recommendation section 14.3]

10.1.2 Maximum Analytical Limit (ALMAX)

In order to ensure the degraded voltage relays do not inadvertently operate, a maximum analytical limit is required. The maximum analytical limit for the 480 volt Class 1E bus degraded voltage protection has been chosen to be 432 volts, which is 90% of the 480 volt rating of the busses. Transposing this value through the 480/120 volt bus PT produces a voltage of 108.0 volts. This is the maximum voltage at which the degraded DA-EE-93-006-08 Page 16 of 49 Revision 5

voltage relay is expected to begin timing during a degraded voltage condition. The relay will not begin timing for all voltages above this value.

10.2 Uncertainty Calculation The degraded voltage relays are affected by the following sources of uncertainty and bias:

Ru - relay uncertainty Tu - temperature uncertainty CVu - control voltage uncertainty Du - drift uncertainty MTEu - measurement and test equipment uncertainty Cb - calibration bias PTb - potential transformer bias VDb - voltage drop bias Total Loop Uncertainty (TLU) will be calculated with the following equations:

- TLU = -(Ru 2 + Tu2 + CVu 2 + Du2 + MTEu 2)')2 - Cb - PTb - VDb

+ TLU = (Ru 2 + Tu2 + CVu 2 + Du2 + MTEu2)1'2 + PTh 10.2.1 Relay uncertainty (Ru)

VTD-A0500-4002 states in the "Specifications" section under "Tolerances" that the operating voltage tolerance of +/- 5% is applicable based on use of the printed dial markings. It indicates that the relay may be set precisely using the calibration procedure provided in the vendor document to obtain desired values of operating voltage and delay with excellent repeatability which is defined as variation in control voltage and temperature.

Ginna performs relay calibration utilizing the procedure provided in VTD-A0500-4002, therefore the +/- 5% tolerance does not apply and the relay uncertainty is defined entirely in terms of its temperature uncertainty and control voltage uncertainty.

Therefore the relay uncertainty is +/- 0.0% of a 120 volt span.

10.2.2 Temperature uncertainty (Tu)

VTD-A0500-4002 states in the "Specifications" section under "Tolerances" that there is a 0.5 volt variation in operating voltage over the temperature range 200C to 400C.

The degraded voltage relays are located in the Relay Room and Screenhouse. UFSAR Table 3.11-1 indicates that normal temperature in these locations varies between 50'F and 104oF (100C to 400C). Assuming that the temperature uncertainty can be adjusted linearly over this larger temperature range, the corrected variation is 0.75 volts over the temperature range 10°C to 40'C. [refer to assumption 5.2]

DA-EE-93-006-08 Page 17 of 49 Revision 5

This is (0.75 volts)/(120 volts) or 0.625% of a 120 volt span. The relay temperature uncertainty is therefore +/- 0.625% of a 120 volt span.

10.2.3 Control Voltage Uncertainty (CVu)

VTD-A0500-4002 states in the "Specifications" section under "Control Power" that the allowable variation in control voltage is 100 to 140 volts and in the "Tolerances" section that there is a 0.2 volt variation in operating voltage for a 10 volt variation in control voltage.

The highest voltage on the DC distribution system occurs during equalization of the vital batteries. Technical Specifications bases section B3.8.4 indicates that the normal equalize voltage of the battery chargers is limited to less than or equal to 140 volts when tied to the DC electrical power distribution system, due to the voltage rating of various components and fuses. Therefore the upper voltage limit is 140 volts.

Technical Specifications Bases section B3.8.4 indicates that the minimum voltage limit forthe batteries is 2.13 volts per cell, which corresponds to a total minimum voltage output of 128 volts per battery.

Actual voltage at the degraded voltage relays will be slightly below these values due to cable impedance. Voltage drop is not required to be factored into this evaluation since the actual parameter being evaluated is the range between highest and lowest voltages.

Calibration procedure PR-1.1 requires the control voltage to be adjusted to 134 volts when performing calibration, therefore control voltage will vary by (140 volts - 128 volts) = 12 volts which can be represented as +/- 6 volts variation from the calibration voltage. Assuming that the variation in operating voltage is proportional to the variation in control voltage, the variation in operating voltage is calculated as +/- (6 volts / 10 volts)(0.2 volts) =

0. 12 volts. This is +/- 0.10% of a 120 volt span. [refer to assumptions 5.31 10.2.4 Drift uncertainty (Du) contains an IHPA computer run which calculated a 900 day drift of +/-

0.5997% of a 120 volt span and a maximum expected value of 0.6265% of a 120 volt span for the degraded voltage relays. For conservatism, the maximum expected value will be used, therefore the drift uncertainty is +/- 0.63% of a 120 volt span.

10.2.5 M&TE uncertainty (MTEu)

A review of work orders determined that the Doble F2200 test set was used to calibrate the degraded voltage relays. The typical uncertainty for the Doble test set is +/- 0.25%.

The typical value will be used, therefore M&TE uncertainty is +/- 0.25% of a 120 volt span.

10.2.6 Calibration bias (Cb)

DA-EE-93-006-08 Page 18 of 49 Revision 5

The nominal setting for the degraded voltage relay is 105.2 volts (setpoint SP-3526). In order to create a negative bias at the nominal setting, procedure PR-1.1 requires calibration between 105.2 and 105.7 volts (105.2, +0.5, -0.0 volts). The + 0.5 volts is 0.417% of 120 volts. The calibration bias is therefore -0.42% of a 120 volt span.

NOTE: The bias is equivalent to reducing the voltage to the relay and is therefore a negative bias which will be added to the negative TLU.

10.2.7 Potential Transformer bias (PTb)

Potential transformer accuracy depends on its accuracy class and the total connected burden. Nameplate information for the PT is documented in CMIS:

Westinghouse 480/120.volt potential transformers, style 254A481G04, type EMPL 0.6, ACC CL IL-44-060-2 line 7, FW impulse test 10KV. Thermal ratings at ambient temperatures are 750 VA at 30 degrees C, 500 VA at 55 degrees C. contains Westinghouse bulletin 44-204 which shows that the type EMPL potential transformer has'an accuracy rating of +/- 0.3% for burdens up to 75 VA and 85%

power factor (for W, X and Y burdens).

Based on drawings 10905-0054 sheet 3, 10905-0055 sheet 3, 10905-0056 sheet 3 and 10905-0057 sheet 3, the total burden on a PT consists of a type 27 and a type 27N relay.

VTD-A0500-4002 identifies the burden of the 27 relay as 1.2 VA and VTD-A0500-4201 identifies the burden of the 27N relay as less than 0.5 VA. The total burden is therefore 1.7 VA.

The total burden of 1.7 VA is less that 75 VA, therefore the potential transformer bias is

+/- 0.3% of a 120 volt span.

10.2.8 Voltage Drop bias (VDb)

A review of drawings 21946-0054, 21946-0055, 21946-0056 and 29146-0057 and circuit schedules L665, L666,(L683 and L684 shows that maximum cable length is 520 feet for circuit L683. The cable is #14 AWG and per Chapter 9, Table 9 of the NEC Handbook, impedance is 3.1 + jO.073 ohms/1000 ft.

Total burden on the PT is 1.7 VA (refer to section on potential transformer bias).

-1 = (1.7 VA)/120V = 0.014 A R = 2(520 ft)(3.1 + jO.073 ohms/1000 ft) = 3.224 + j 0.0759 ohms = 3.22 ohms Voltage drop = IR = (0.014A)(3.22 ohms) = 0.045 volts which is -0.038% of a 120 volt span.

Therefore the voltage drop uncertainty is a bias of -0.038% of a 120 volt span.

DA-EE-93-006-08 Page 19 of 49 Revision 5

NOTE: The bias is equivalent to reducing the voltage to the relay and is therefore a negative bias which will be added to the negative TLU.

This represents 92 volts at the low side of the 480/120 volt bus PT's. Voltage will be divided into three ranges:

• 92 volts to 96 volts (368 volts to 384 volts) 96 volts to 108.54 volts (384 volts to 434.16 volts) 108.54 volts and higher (434.16 volts and higher) 92 Volts to 96 Volts For voltages between 92 volts and 96 volts, the minimum analytical limit for degraded voltage relay time delay will be 20 seconds. This value provides adequate time for the motors to accelerate, without bus voltage remaining in a degraded voltage condition for an extended period of time. The value of 20 seconds will be compared against the time-voltage curve of the degraded voltage relays and the 480 DA-EE-93-006-08 Page 21 of 49 Revision 5

volt bus recovery voltage later in this calculation for the most limiting condition when the busses are being supplied by offsite power. For the scenario when the emergency diesel generators are providing power to the 480 volt busses, the dynamic analyses for the emergency diesel generators (DA-EE-92-111-01 and DA-EE 112-01) have been reviewed and determined not to be the limiting condition for evaluation. These analyses provide voltage profiles for the 480 volt busses while starting the safeguards sequence loads and demonstrate that the responsiveness of the exciter on the diesel generators causes bus voltage to rise significantly faster than scenarios when the 480 volt busses are powered from the offsite circuits. There are pending changes to these analyses, however the changes have been reviewed and are not expected to significantly alter the acceleration time of the motors.

96 Volts to 108.54 Volts The least amount of margin between actuation of the degraded voltage relays and the responsiveness of bus voltage occurs during the safeguards sequence with circuit 767 as the single source of offsite power. The coordination curve in the results section of this calculation contains the time-voltage curve for bus voltage recovery. The minimum analytical limit for time must be a point selected above the time-voltage curve for bus voltage recovery. Any point above this line, which appears as step changes in voltages due; to voltage regulator tap changes is acceptable. The analytical limit must also be chosen to ensure it is below the curve which represents the reset voltage of the degraded voltage relays which is fixed at a value 0.5% higher than the operate setting. For the purpose of this analysis, the minimum analytical limit for time will be represented by the equation for the degraded voltage relay reset associated with the maximum analytical limit for voltage at which the relay will actuate. This curve will provide the minimum analytical limit for time for all 480 volt bus voltages above 384 volts (80% of 480 volts) and is defined by the equation:

V = (108.54)(1-e°'

0" 3" 5 -1' T) @ 120 volt base voltage Solving the equation for time at the minimum calculated setpoint for voltage (105.0):

105.0 = (108.54)(1-e (°°(13.5 -)))

(105.0/108.54) = (1-e( 0.08 3" 5 -1))

(105.0/108.54) -

= -e( 00 8(13 "5 - T))

-(105.0/108.54) + 1 = e(0.08(13.5-13)

Ln[-(105.0/108.54) + 1] = 0.08(13.5 - T)

(1/0.08)(Ln[-(105.0/108.54) + 1]) = 13.5 - T T = 13.5 - (1/0.08)(Ln[-(105.0/108.54) + 1])

T = 56.3 seconds ALMIN@ Io5.o = 56.3 seconds Solving the equation for time at the maximum calculated setpoint for voltage (105.9):

105.9 = (108.54)(1-e(0.08' 3 5 - T)))

(105.9/108.54) = (1-e(°'° 3 "-1 )

(105.9/108.54) - 1 = -e( 0 "0 8(13'5 - 1 3 )

-(105.9/108.54) + 1 = e-(0.0(135-T)

DA-EE-93-006-08 Page 22 of 49 Revision 5

Ln[-(105.9/108.54) + 1 ] = 0.08(13.5 - T)

(1/0.08)(Ln[-(105.9/108.54) + 1]) = 13.5 - T T = 13.5 - (1/0.08)(Ln[-(105.9/108.54) + 1])

T = 60.0 seconds ALMIN@105.9 = 60.0 seconds The coordination curve in the results section of this calculation indicates the minimum margin between the degraded voltage reset and the bus voltage occurs between 106.0 and 107.0 volts.

108.54 Volts and Higher NEMA standard design requires equipment to be designed for normal operation at nominal rating +/- 10%. Therefore equipment rated 480 volts is capable of continuous operation at (480 volts)(0.90) = 432 volts or 108 volts on a 120 volt base. Therefore for proper coordination with the degraded voltage relay reset, there is no requirement for a minimum analytical limit for degraded voltage relay time delay for all voltages above 108.54 volts.

10.3.2 Maximum Analytical Limit for Degraded Voltage Relay Time Delay The degraded voltage relays have an inverse time trip characteristic curve. The formula for the curve was determined to be matched by the equation V =

(VsET7rNG)(1-e(0. 080'3.5 -

) ), where T is time and the value to be inserted for VSEMING is the operate or reset coefficient [see assumption 5. 11. The exponential function of the degraded voltage relays, results in the time-voltage curve becoming vertical as time increases.

In theory, an upper bound is required for the vertical portion of the degraded voltage relay characteristic curve, to ensure equipment protection is adequate. As time increases when equipment operates in a degraded voltage condition, equipment is susceptible to damage from thermal heating.

The minimum analytical limit for the operate voltage of the degraded voltage relays was selected to be 414 volts in a previous section of this calculation. This value is based on the 90% start rating of the motors with a terminal voltage rating of 460 volts. The equipment is capable of continuous operation at this voltage. No thermal damage is expected to occur on 440 and 460 volt rated equipment at voltages of 414 volts and higher. For any equipment rated 480 volts, this would be an area of concern for very long term operation.

Since the minimum analytical limit of the degraded voltage relays has been set at 414 volts, the setpoints calculated should provide a 95% confidence level that the degraded voltage relays will actuate prior to bus voltage falling below 414 volts. In order to provide protection for equipment a maximum analytical limit for time will be established.

DA-EE-93-006-08 Page 23 of 49 Revision 5

Ginna utilizes 125 seconds as the maximum calculated setpoint for relay actuation.

This was chosen as a conservative value to minimize the potential for thermal degradation for operation below 414 volts. This value will be retained and the maximum analytical limit will be calculated from the maximum calculated setpoint using the equation below:

CSMAX = ALMx +(- TLU)

ALMAx = CSMAx - (- TLU)

The value for - TLU will be determined later in this calculation to be - 11.8 seconds.

Therefore:

ALMAx = 125 seconds - (- 11.8 seconds)

ALMAX = 125 seconds + 11.8 seconds ALMAX = 136.8 seconds Utilizing an analytical limit of 136.8 seconds is considered a conservative time delay.

The loads connected to the bus are rated for terminal voltages of 440, 460 and 480 volts and are rated for continuous operation at 90% of the terminal voltage rating.

ANSI Standard C50.41 provides criteria for the momentary operation of motors, which requires motors to be capable of operating at rated load for a minimum of 60 seconds when 75 percent of rated voltage at rated frequency is applied to the motor terminals. The thermal capability curves for 440, 460 and 480 volt motors have been added to the coordination curve in section 11. The actual slope of the thermal capability curves follow an exponential function, however they have been depicted as straight lines for the small voltage range at which they are plotted. The distance between the motor thermal capability curves and the degraded voltage relay characteristic curve represents the margin in time before thermal degradation would be expected to occur. Due to voltage drop in the motor feeder cables, actual voltage at the terminals would be slightly lower than the value as indicated by the thermal capability curves. Based on engineering judgement, this is considered negligible in comparison to the margin (in time) available. [See assumption 5.5]

10.4 Uncertainty Calculation The time delay for the degraded voltage relays is affected by the following sources of uncertainty and bias:

Rut - relay uncertainty Tut - temperature uncertainty CVut - control voltage uncertainty Dut - drift uncertainty MTEut - measurement and test equipment uncertainty Cut - calibration uncertainty PTbt - potential transformer bias Total Loop Uncertainty (TLU) is calculated with the following equations:

DA-EE-93-006-08 Page 24 of 49 Revision 5

- TLU = -(Rut2 + Tut2 + CVut2 + Dut2 + MTEuL + Cut)" - PTbt

+ TLU = (Rut2 + Tut2 + CVut + Dut + MTEut + Cut2)1/2 + PTbt 10.4.1 Relay uncertainty (Rut)

VTD-A0500-4002 states in the "Specifications" section under "Tolerances" that the operating time tolerance of 4-10% is applicable based on use of the printed dial markings. It indicates that the relay may be set precisely using the calibration procedure provided in the vendor document to obtain desired values of operating voltage and delay with excellent repeatability. Repeatability is defined as variation in control voltage and temperature.

Ginna performs relay calibration utilizing the procedure provided in VTD-A0500-4002, therefore the +/- 10% tolerance does not apply and the relay uncertainty is defined entirely in terms of its temperature uncertainty and control voltage uncertainty. Therefore the relay uncertainty is +/- 0.0%.

10.4.2 Temperature uncertainty (Tut)

VTD-A0500-4002 does not specify time delay accuracy for variations in temperature.

For the purposes of this calculation an uncertainty will be added for calculation of the time delay temperature uncertainty. A value of +/- 0.625% will be used, which is equivalent to the value used for the temperature uncertainty associated with voltage.

10.4.3 Control Voltage Uncertainty (CVut)

VTD-A0500-4002 does not specify time delay accuracy for variations in control voltage.

For the purposes of this calculation an uncertainty will be added for calculation of the time delay control voltage uncertainty. A value of +/- 0.10% will be used, which is equivalent to the value used for the control voltage uncertainty associated with the relay.

10.4.4 Drift uncertainty (Dut) contains a summary of as found relay drift during testing. The worst case results for a relay were 9.73 seconds between maximum and minimum values. For conservatism this calculation will use +/- 9.73 seconds for drift. Utilizing the maximum analytical limit for time (136.8 seconds) as the span results in a value of +/- 7.11% of span.

10.4.5 M&TE uncertainty (MTEut) contains Dranitz manufacturer data. The Dranitz model 325 polymeter's time measurements accuracy is +/- 0.003% of reading (+/- least significant digit). Test timing is performed on the 0 to 999.99 or 0 to 99.999 second range. Utilizing the maximum analytical limit for time (136.8 seconds) as the span, measurement accuracy is DA-EE-93-006-08 Page 25 of 49 Revision 5

therefore +/- (0.003%)(136.8 seconds) + 0.01 seconds = +/- 0.014 seconds. Therefore the time delay MTEut is equal to +/- 0.014% of a 136.8 second span.

10.4.6 Calibration uncertainty (Cut)

Past revisions of procedure PR-1.1 calibrated the degraded voltage relays at 92 volts with a time delay of 40 seconds and an as-left tolerance of " 1.0 second. Since the relay was calibrated at the single point, an uncertainty of 1.0/40

+/- 2.5% was applied. The procedure is being revised to set the relay at 105.2 volts and perform testing at 105.0 volts, therefore using the equation from section 5.1 (assumptions) the new calibration value for time will be:

105.0 = (105.2)(1-e(°008 0'3.5 - 1M))

(105.0/105.2) = (1-e(°0.'0 3 5 -T)))

(105.0/105.2) - I = -ei(0.8(3.5 - T))

-(105.0/105.2) + 1 = e(°'08(135-T)

Ln[-(105.0/105.2) + 11 = 0.08(13.5 - T)

(1/0.08)(Ln[-(105.0/105.2) + 1]) = 13.5 - T T = 13.5 - (1/0.08)(Ln[-(105.0/105.2) + 1j)

T = 91.8 seconds (setpoint SP-4042)

Since the relay is only calibrated at the single point, a calibration uncertainty of +/- 2.5%

will continue to be utilized which is +/-2.3 seconds.

10.4.7 Potential Transformer bias (PTbt)

The potential transformers have an accuracy of +/- 0.3% of span. The change in time delay for a given change in voltage will vary non-linearly according to the time-voltage equation which is an exponential function. The minimum calculated setpoint for voltage was calculated as 105.0 volts and the maximum calculated setpoint for voltage was calculated as 105.9 volts. In order to add a potential transformer bias a slope will be utilized for the straight line between the minimum and maximum calculated voltage setpoints. The minimum analytical limit for time at 105.0 volts has been calculated to be 56.3 seconds and the minimum analytical limit for time at 105.9 volts has been calculated to be 60 seconds. A straight line between these points would have a slope of (60-56.3)/(105.9-105.0) or 4.1 seconds per volt. Combining these terms, +/- 0.3%(120 volts)(4.1 seconds/volt) = 1.48 seconds. Utilizing the maximum analytical limit for time (136.8 seconds) as the span, measurement bias is +/-(1.48 seconds)/(136.8 seconds) = _

0.0108 or +/- 1.08%.

Engineered safeguards sequence motors on Ginna's 480 volt Class l E busses are rated 440 and 460 volts. They are designed for 80% degraded voltage starting and 90%

degraded voltage continuous operation [see assumption 5.41. Utilizing the 80% rating for starting, the 440 volt motors can start at 352 volts and the 460 volt motors can start at 368 volts.

The minimum analytical limit for the 480 volt Class 1E bus loss of voltage protection is 368 volts. This value is based on the NRC Safety Evaluation Report dated 3/26/1981 for Amendment No. 38 to Provisional Operating License which approved the loss of voltage relay setpoint of greater than or equal to 368 volts. Transposing this value through the 480/120 volt bus PT produces a voltage of 92.0 volts. This is the minimum voltage at which the loss of voltage relay is expected to begin timing during an undervoltage condition. The loss of voltage relays will begin timing for all voltages below the minimum analytical limit.

A bus voltage of 368 volts would result in a slightly lower voltage at the terminals of the motors due to the voltage drop in the motor feeder cables. Running motors are constant DA-EE-93-006-08 Page 28 of 49 Revision 5

power devices. Therefore as terminal voltage decreases current requirement increases.

Starting motors are modeled differently than running motors. Starting motors are constant impedance devices resulting in decreasing locked rotor current as bus voltage decreases. The motors will therefore not draw maximum locked rotor current for this short period of time when the bus voltage drops and subsequently recovers. The short time delay associated with the loss of voltage relays will ensure the busses are tripped in a true loss of voltage scenario.

11.1.2 Maximum Analytical Limit (ALMAX)

In order to ensure the loss of voltage relays do not inadvertently operate, a maximum analytical limit is required. The maximum analytical limit for the 480 volt Class 1E bus loss of voltage protection has been chosen to be 381.2 volts which is 79.42% of the 480 volt bus rated voltage. This value was chosen to allow a conservative margin above the wost case value which is found in case 1 16L_2007_AB from DA-EE-96-068-03 (Offsite Power Load Flow Study) to ensure the time delay coordinates with the most limiting (recoverable) grid voltage conditions. The actual worst case voltage from case 11 6L_2007_AB is 79.64% of bus voltage. Therefore, using the conservative value of 381.2 volts and transposing this value through the 480/120 volt bus PT produces a voltage of 95.3 volts. This is the maximum voltage at which the loss of voltage relay is expected to begin timing during an undervoltage condition. The relay will not begin timing for all voltages above this value.

11.2 Uncertainty Calculation The loss of voltage relays are affected by the following sources of uncertainty and bias:

Ru - relay uncertainty Tu - temperature uncertainty CVu - control voltage uncertainty Du - drift uncertainty MTEu - measurement and test equipment uncertainty Cb - calibration bias PTb - potential transformer bias VDb - voltage drop bias Total Loop Uncertainty (TLU) will be calculated with the following equations:

- TLU = -(Ru2 + Tu2 + CVu2 + Du 2 + MTEu2)112 -Cb-PTb-VDb

+ TLU = (Ru2 + Tu2 + CVu2 + Du2 + MTEu2) t2 + PTb VTD-A0500-4201 states in the "Specifications" section under "Tolerances" that the operating voltage tolerance of +/- 2% is applicable based on use of the printed dial markings.

It indicates that more precise settings may be determined with three tolerances which should be considered independent and may be cumulative. The three tolerances are (1) constant DA-EE-93-006-08 Page 29 of 49 Revision 5

temperature and constant control voltage, (2) variation over allowable DC control voltage range and (3) variation over temperature range.

Constant temperature and constant control voltage will be calculated in the relay uncertainty section (Ru). Variation over allowable DC control voltage range will be calculated in the control voltage uncertainty section (CVu). Variation over temperature range will be calculated in the temperature uncertainty section (Tu).

11.2.1 Relay uncertainty (Ru)

VTD-A0500-4201 states in the "Specifications" section under "Tolerances" that repeatability at constant temperature and constant control voltage is +/- 0.1%. Therefore relay uncertainty is +/- 0.1% of a 120 volt span.

11.2.2 Temperature uncertainty (Tu)

The 27N relays contain the harmonic filter option. VTD-A0500-4002 states in the "Specifications" section under "Harmonic Filter" that the relay tolerance is +/- 0.4%

between 10TC and 40TC.

The loss of voltage relays are located in the Relay Room and Screenhouse. UFSAR Table 3.11-1 indicates that normal temperature in these locations varies between 50TF and 104 01 (100C to 400C).

Therefore the temperature uncertainty is +/- 0.4% of a 120 volt span.

11.2.3 Control Voltage Uncertainty (CVu)

VTD-A0500-4201 states in the "Specifications" section under "Tolerances" that repeatability over the allowable DC control power range is +/- 0.1 %. The VTD also identifies in the "Specifications" section under "Control Power" that the allowable variation for the 125 VDC relays is 100 to 140 volts.

The highest voltage on the DC distribution system occurs during equalization of the vital batteries. Technical Specifications bases section B3.8.4 indicates that the normal equalize voltage of the battery chargers is limited to less than or equal to 140 volts when tied to the DC electrical power distribution system, due to the voltage rating of various components and fuses. Therefore the upper voltage limit is 140 volts.

Technical Specifications Bases section B3.8.4 indicates that the minimum voltage limit for the batteries is 2.13 volts per cell, which corresponds to a total minimum voltage output of 128 volts per battery.

Actual voltage at the degraded voltage relays will be slightly below these values due to cable impedance. Voltage drop is not required to be factored into this evaluation since the actual parameter being evaluated is the range between highest and lowest voltages.

DA-EE-93-006-08 Page 30 of 49 Revision 5

Assuming that the variation in control voltage is linear over the 100 to 140 volt range (40 volt span), then the value can be adjusted for the actual control voltage range between 128 and 140 volts (12 volts span). [Refer to assumption 5.6] The uncertainty is therefore

(+/-0.1%)(12/40) = 0.03% of a 120 volt span.

I 1.2.4 Drift uncertainty (Du) contains an IHPA computer run which calculated a 900 day drift of +/-

0.2411% of a 120 volt span and a maximum expected value of -0.279% of a 120 volt span for the loss of voltage. For conservatism, the maximum expected value will be used, therefore the drift uncertainty is +/- 0.28% of a 120 volt span.

11.2.5 M&TE uncertainty (MTEu)

A review of work orders determined that the Doble F2200 test set was used to calibrate the degraded voltage relays. The typical uncertainty for the Doble test set is +/- 0.25%.

The typical value will be used, therefore M&TE uncertainty is +/- 0.25% of a 120 volt span.

11.2.6 Calibration bias (Cb)

The nominal setting for the loss of voltage relay is 93.2 volts (setpoint SP-2309). In order to create a negative bias at the nominal setting, procedure PR-1.1 requires calibration between 93.2 and 93.7 volts (93.2, +0.5, -0.0 volts). The + 0.5 volts is 0.417% of 120 volts. The calibration bias is therefore -0.42% of a 120 volt span.

NOTE: The bias is equivalent to reducing the voltage to the relay and is therefore a negative bias which will be added to the negative TLU.

11.2.7 Potential Transformer bias (PTb)

Potential transformer accuracy depends on its accuracy class and the total connected burden. Nameplate information for the PT is documented in CMIS:

Westinghouse 480/120 volt potential transformers, style 254A481G04, type EMPL 0.6, ACC CL IL-44-060-2 line 7, FW impulse.test 10KV. Thermal ratings at ambient temperatures are 750 VA at 30 degrees C, 500 VA at 55 degrees C. contains Westinghouse bulletin 44-204 which shows that the type EMPL potential transformer has an accuracy rating of +/- 0.3% for burdens up to 75 VA and 85%

power factor (for W, X and Y burdens).

Based on drawings 10905-0054 sheet 3, 10905-0055 sheet 3, 10905-0056 sheet 3 and 10905-0057 sheet 3, the total burden on a PT consists of a type 27 anda type 27N relay.

VTD-A0500-4002 identifies the burden of the 27 relay as 1.2 VA and VTD-A0500-4201 identifies the burden of the 27N relay as less than 0.5 VA. The total burden is therefore 1.7 VA.

DA-EE-93-006-08 Page 31 of 49 Revision 5

The total burden of 1.7 VA is less that 75 VA, therefore the potential transformer bias is

+/- 0.3% of a 120 volt span.

11.2.8 Voltage Drop bias (VDb)

A review of drawings 21946-0054, 21946-0055, 21946-0056 and 29146-0057 and circuit schedules L665, L666, L683 and L684 shows that maximum cable length is 520 feet for circuit L683. The cable is #14 AWG and per Chapter 9, Table 9 of the NEC Handbook, impedance is 3.1 +jO.073 ohms/1000 ft.

Total burden on the PT is 1.7 VA (refer to section on potential transformer bias).

I = (1.7 VA)/120V = 0.014 A R = 2(520 ft)(3.1 + jO.073 ohms/1000 ft) = 3.224 + j 0.0759 ohms = 3.22 ohms Voltage drop = IR (0.014A)(3.22 ohms) = 0.045 volts which is -0.038% of a 120 volt span.

Therefore the voltage drop uncertainty is a bias of -0.038% of a 120 volt span.

NOTE: The bias is equivalent to reducing the voltage to the relay and is therefore a negative bias which will be added to the negative TLU.

11.3 Loss of Voltage Relay Time Delay Setpoints The following design analyses have evaluated bus voltages during various loading scenarios:

DA-EE-96-068-03, Offsite Power Load Flow Study DA-EE-92-111-01, EDG A Dynamic Analysis DA-EE-92-112-01, EDG B Dynamic Analysis The time delay associated with the loss of voltage relays is required to actuate fast enough to avoid prolonged stalling of motors in the event of a loss of voltage and also be sensitive enough to permit momentary recoverable voltage dips when large motors are started.

11.3.1 Minimum Analytical Limit for Loss of Voltage Relay Time Delay The difference in source strength between the diesel generators and the offsite circuits has a significant impact on the 480 volt bus voltages during dynamic conditions. When the 480 volt safeguards busses are supplied from the grid, the voltage drop during the safeguards sequence will not be the limiting condition for evaluation of the loss of voltage relays. The largest magnitude voltage drop occurs when the emergency diesel generators are supplying power. Analysis of the variations in bus voltage during the safeguards sequence contained in the EDG A Dynamic Analysis and EDG B Dynamic Analysis indicates that the loss of voltage relays will operate for certain scenarios. These are recoverable scenarios, as shown in the analyses. Although highly improbable, the worst case scenarios analyzed for bounding conditions are the cases in which the containment spray motors and containment fans are started concurrently (attachment J9 in each analysis). The resulting plots of bus voltage versus time are below. The difference between dropout and pickup on the loss of voltage relays is 1% (refer to assumption 5.10). By inspection of the graphs, when voltage drops below 80% (which is higher than the loss of voltage relay maximum analytical limit previously calculated) a minimum time delay of 2 seconds will provide sufficient time for the diesel generator exciter to respond and raise bus voltage above 81% (which is higher than the actual reset value associated with an 80% dropout) of the loss of voltage relays. Therefore selecting a minimum analytical limit of 2 seconds bounds by the cases evaluated.

40 There are pending changes to the EDG dynamic analyses, however the changes have been reviewed and are not expected to significantly alter the acceleration time of the motors or the minimum analytical limit established as 2.0 seconds.

11.3.2 Maximum Analytical. Limit for Loss of Voltage Relay Time Delay DA-EE-93-006-08 Page 35 of 49 Revision 5

The loss of voltage relays have a maximum analytical limit established in order to assure the time delays associated with actuation of the undervoltage protection scheme and subsequent starting of the emergency diesel generators and initiation of safeguards sequence loads are adequate. A maximum time delay for the loss of voltage relays has been established as 2.75 seconds. The time delay for undervoltage system actuation is 12.75 seconds (setpoint SP-2325) which includes 275 seconds for undervoltage actuation and 10 seconds for diesel starting. This value is utilized in the COLR and Technical Specifications.

11.4 Uncertainty Calculation The time delay for the loss of voltage relays is affected by the following sources of uncertainty and bias:

Rut - relay uncertainty Tut - temperature uncertainty CVut - control voltage uncertainty Dut - drift uncertainty MTEut - measurement and test equipment uncertainty Cut - calibration uncertainty Total Loop Uncertainty (TLU) is calculated with the following equations:

- TLU = -(Rut2 + Tut2 + CVut 2 + Dut2 + MTEut' + Cut) "2

+ TLU =(Rut + Tut2 + CVut2 +Dut2 + MTEut2 + Cut)11 11.4.1 Relay uncertainty (Rut)

VTD-A0500-4201 does not specify a time delay accuracy. This accuracy will be conservatively based on how accurate the field calibration is performed. Since the relay is field calibrated to the nearest 0.1 second, the relay time delay accuracy is +/-0.05 seconds which is +/-2.5% of a 2.0 second span, utilizing the minimum analytical limit for time as the span.

11.4.2 Temperature uncertainty (Tut)

VTD-A0500-4002 does not specify time delay accuracy for variations in temperature.

For the purposes of this calculation an uncertainty will be added for calculation of the time delay temperature uncertainty. A value of +/- 0.4% will be used, which is equivalent to the value used for the temperature uncertainty associated with voltage.

11.4.3 Control'Voltage Uncertainty (CVut)

VTD-A0500-4002 does not specify time delay accuracy for variations in control voltage.

For the purposes of this calculation an uncertainty will be added for calculation of the DA-EE-93-006-08 Page 36 of 49 Revision 5

time delay control voltage uncertainty. A value of +/- 0.10% will be used, which is equivalent to the stated tolerance of +/- 0.10% repeatability over the allowable control power range, found in the VTD "Specifications" section under "Tolerances".

11.4.4 Drift uncertainty (Dut) contains a summary of as found relay drift during testing. The worst case results for a relay were 0.03 seconds between maximum and minimum values. For conservatism this calculation. will use +/-0.03 seconds for drift. Utilizing the minimum analytical limit for time as the span (2.0 seconds), drift uncertainty becomes +/-1.5% of span.

11.4.5 M&TE uncertainty (MTEut) contains Dranitz manufacturer data. The Dranitz model 325 polymeter's time measurements accuracy is +/- 0.003% of reading (+/- least significant digit), Test timing is performed on the 0 to 999.99 or 0 to 99.999 second range. Utilizing the minimum analytical limit for time (2.0 seconds) as the span, measurement accuracy is therefore +/- (0.003%)(2.0 seconds) + 0.01 seconds = +/- 0.016 seconds. Therefore the time delay MTEut is equal 0.016/2.0 = +/-0.8% of a 2.0 second span.

11.4.6 Calibration uncertainty (Cut)

Procedure PR-1.1 indicates that the time delay relays are calibrated at 2.4 seconds (setpoint SP-23 11) with an as left tolerance of +/-_0.12 seconds. An as-left tolerance of

+0.12 seconds represents an uncertainty of +/-6.0% of a 2.0 second span.

12.0 Calculations/Computations for Bus Voltmeters (Type KA-241)

There are four analog voltmeters for the 480 volt safeguards busses located on the Main Control Board.

12.1 Contributions to Uncertainty The voltmeters are affected by the following sources of uncertainty and bias:

RAu - Reference Accuracy uncertainty Ru - Readability uncertainty Tu - Temperature uncertainty Du - Drift uncertainty MTEu - Measurement and Test Equipment uncertainty CTu - Calibration Tolerance uncertainty PTb - Potential Transformer bias VDb - Voltage Drop bias Total Loop Uncertainty (TLU) will be calculated with the following equations:

-TLU =-(RAu2 + Ru2 + Tu2 + Du2 + MTEu2 +CTu2)/ - PTb - VDb

+ TLU =(RAu2 + Ru2 + Tu2 + Du2 + MTEu 2 +CTu2)1/2 + PTb 12.1.1 PT bias (PTb):

There are two potential transformers which step down the bus voltage for input to the voltmeters as shown on DWG 33013-1736 sheet 8. A selector switch determines the phase voltage to be measured. The PTs are Westinghouse style 7526A02G04, 480/120V, 0.6%

accuracy class at W burden and 1.2% accuracy class at X burden according to Attachment 11, Westinghouse Product Bulletin 44-200A.

The total burden on the PT is from the KA-241 Voltmeter. Other connected equipment includes the Basler Sync-check relay type BE1-25, and the KI-241 Synchro-scope with the associated voltmeter which can be neglected because these instruments will only be introduced into the circuit momentarily during monthly testing of the diesel generators.

These instruments will not be used during all other operating conditions.

Attachment # 8 contains the Westinghouse Application Data publication 43-200 which indicates the AC burden on the PT from the KA-241 Voltmeter is 1.92Watts at 120V. At 150V, this will be 2.4Watts based on the following:

150Volts (1.92Watts @ 120Volts)1

= 2.4AWatts @ 150Volts 120Volts The ASA Standard 'W Burden' is 12.5VA with a power factor as low as. 1; The burden on this PT falls into this category. Therefore, the accuracy class of.6% will apply.

12.1.2 Voltage Drop bias (VDb):

A review of drawings 21946-0054, 21946-0055, 21946-0056, and 21946-0057 and circuit schedules L181, L312, L425 and L582 shows that maximum calbe length is 350 feet (each) for circuits L425 and L502. The cable is #10 AWG. run in conduit for 120 feet. For conservatism, the entire run will be considered to be run in steel conduit. Each run will total 700 feet. The impedance of the conductor is 1.2+jO.063 ohms/1000ft according to the NEC handbook Chapter 9 Table 9. The total burden on a PT consists of a type KA-241 voltmeter with a burden of 2.4Watts at 150Volts (refer to section on PT bias).

Total burden on the PT is 2.4 watts (refer to section on potential transformer bias).

I = (2.4 VA)/150V = 0.016 A R -- 2(350 ft)(1.2 + jO.063 ohms/1000 ft) = 0.84 +j 0.0441 ohms = 0.84 ohms Voltage drop = IR = (0.016A)(0.084 ohms) = 0.0134 volts which is 0.009% of a 150 volt span.

This voltage drop is therefore.009% of a 150V span.

12.1.3 Measurement and Test Equipment Uncertainty (MTEu):

Attachment # 10 contains a copy of vendor data sheets for the Arbiter Model 1040C which is used for calibration. It indicates that accuracy is 0.25%

12.1.4 Reference Accuracy (RAu):

According to VTD-W0120-4470, the rated accuracy class of the KA-241 is 1%.

12.1.5 Drift (Du):

The drift associated with the voltmeters will be assumed to be equal to the reference accuracy of 1%. (See assumption 5.11) 12.1.6 Readability uncertainty (Ru):

There is no vendor data available for the readability of the meter. Readability will be based on half of the smallest demarcation on the scale. The voltmeter is divided in demarcations of 10 Volts so the readability uncertainty will be 5 volts or.83% of the 600 volt scale.

13.2 The chart on the following page depicts the characteristic curves for the degraded voltage relays with the new calculated setpoints. The most limiting 480 volt bus voltage is also shown (which appears as a step function) as well as the thermal capability curves for equipment connected to the bus (see assumption 5.5). The chart demonstrate the proper application of the degraded voltage relays to ensure equipment protection and provide proper coordination with the bus voltage recovery during the most limiting degraded voltage condition.

The Class 1E 480 volt safeguards busses 14, 16 17 and 18 are normally fed from the offsite sources (circuit 7T and circuit 767). The safeguards busses are backed by the emergency diesel generators in order to provide AC power in the event that offsite power is not available. The worst case voltages occur on the 480 volt safeguards busses during the sequential starting of emergency safeguards sequence loads.

The following design analysis have evaluated bus voltages during various loading scenarios:

DA-EE-96-068-03, Offsite Power Load Flow Study DA-EE-92-1 11-01, tDG A Dynamic Analysis DA-EE-92-112-01, EDG B Dynamic Analysis The differences in source strength between the diesel generators and the offsite circuits have a significant impact on the 480 volt bus voltages during dynamic conditions. During the most limiting voltage conditions on the grid, voltage will drop at the start of the safeguards sequence and the voltage recovery will be determined by the automatic tap changer responding and stepping up voltages in time periods equal to the maximum delay associated with the operation of the tap changer. This time delay will be the most limiting condition for analysis of degraded voltage relay response since the recover of voltage will be competing against the timing of the degraded voltage relay.

A summary of the calculated worst case bus voltages is contained in section 2.1 of the Offsite Power Load Flow Study. This indicates the worst case voltage occurs on bus 14 during an accident scenario with circuit 767 providing offsite power, analyzed in load flow case 116L_2007.AB. The minimum voltage is calculated as 79.64% of the 480 volt bus rating, or 382.3 volts.

Assessment of Calculations vs. Accettance Criteria #1 The chart for the degraded voltage relays in section 13.2 and the chart for the loss 'of voltage relays in section 13.3 demonstrate that the setpoints have been properly applied to coordinate with the range of potential bus voltages and the limiting conditions for protection of loads.

The degraded voltage relays have been shown to provide enough time delay for the loads to energize for the most limiting condition with offsite power supplying power to the safeguards busses. The loss of voltage relays have been set at a value which will permit the DA-EE-93-006-08 Page 46 of 49 Revision 5

relay to reset when bus voltage recovers during the most limiting condition when three motors start concurrently during the safeguards sequence (highly improbable scenario).

Acceptance Criteria #2 Degraded voltage relays shall be set to allow operation of connected loads,' at degraded voltages (above the equipment ratings) and actuate at a degraded voltage (below equipment ratings) to ensure equipment thermal damage does not occur due to the degraded voltage condition.

Assessment of Calculations vs. Acceptance Criteria #2 The minimum calculated setpoint for the degraded voltage relays has been determined to be 105.0 (420 volts on the 480 volt bus) volts and the maximum calculated setpoint determined to be 105.9 volts (423.6 volts on the 480 volt bus). As shown on the chart in section 13.2, the degraded voltage relays will actuate as low as 103.5 volts (414 volts on the 480 volt bus) when accounting for the uncertainty and bias terms associated with the degraded voltage relays. Actuation of the degraded voltage relays above 414 volts will ensure that equipment is protected from thermal damage due to a degraded voltage condition. The curve also shows the margin available between equipment thermal capability curves and degraded voltage relay actuation.

Acceptance Criteria #3 The loss of voltage relays shall be set to detect a complete loss of voltage.

Assessment of Calculations vs. Acceptance Criteria #3 The minimum analytical limit for the loss of voltage relays is 92 volts (368 volts on the 480 volt bus). This voltage has been established based on the starting capability of the loads fed from the 480 volt bus. Any voltage below this value is considered a complete loss of voltage and the loss of voltage relays are expected to actuate.

Acceptance Criteria #4 The degraded voltage relays shall be set to provide protection from abnormally low voltage.

Assessment of Calculations vs. Acceptance Criteria #4 The chart in section 13.2 contains the coordination curve for the degraded voltage relays and includes curves for the thermal capability of equipment fed from the busses. This chart demonstrates that the degraded voltage relays will actuate before equipment experiences thermal damage' from operation at degraded voltages. Including the uncertainty and bias terms, the degraded voltage relays will actuate between 103.5 volts (414 volts on the 480 volt bus) and 105 volts (432 volts on the 480 volt bus). The most limiting value of 414 volts has been selected since it represents the lowest acceptable, voltage for long term operation of equipment fed from the 480 volt busses.

Accptance Criteria #5 The degraded voltage relays shall not actuate during the engineered safeguards sequence with the busses supplied by the emergency diesel generators.

Assessment of Calculations vs. Acceptance Criteria #5 DA-EE-93-006-08 Pg 7o 9Rvso Page 47 of 49 Revision 5

The setpoints for the degraded voltage relays have been chosen to ensure the relays do not inadvertently actuate during the safeguards sequence. When the 480 volt busses are supplied from the emergency diesel generators bus voltage will drop to a lower value than when the 480 volt busses are supplied from offsite power, however the duration of the voltage dip will be shorter when the busses are supplied by the diesel generators. Therefore the most limiting condition for the actuation of the undervoltage relays is when the 480 volt busses are supplied by offsite power. The chart in section 13.2 shows the voltage profile for the most limiting condition on the 480 volt busses. This chart demonstrates that the voltage will recover before the degraded voltage relays time out and actuate. Since the relays do not actuate for this most limiting condition, they will not actuate for conditions when the 480 volt busses are supplied by the diesel generators.

Acceptance Criteria #6 The time delay on the loss of voltage relays shall be set to prevent inadvertent actuation during actuation of the safeguards sequence loads when the emergency busses are supplied from onsite sources.

Assessment of Calculations vs. Acceptance Criteria #6 The time delay for the loss of voltage relays, including uncertainty and bias terms ranges from 2.0 seconds to 2.75 seconds. These values have been chosen to ensure the loss of voltage relays do not inadvertently actuate. The most limiting condition evaluated (highly improbable) is for a concurrent start of the containment spray pump and two containment fans during actuation of the safeguards sequence. The bus voltage during this scenario will drop below the setpoint of the loss of voltage relays and remain there for approximately 1.5 seconds. The minimum analytical limit selected at 2.0 seconds provides time for the diesel generator to recover bus voltage before the loss of voltage relays actuate.

Accptance Criteria #7 The minimum calculated setpoint for the bus voltmeters should be greater than the operator decision setpoint.

Assessment of Calculations vs. Acceptance Criteria #7 The existing setpoint of 420 volts is less than the calculated minimum setpoint of 431 volts.

See Recommendations in section 14.3.

14.0 Recommendations 14.1 Additional margin between the recovery of bus voltage and the setpoint of the degraded voltage relays can be obtained by blocking the lowest tap setting on the offsite power voltage regulator for circuit 767. TSR 2007-0160 has been initiated to evaluate this recommendation.

14.2 Revise the TRM to include new undervoltage relay setpoints. CA-2007-002776 is tracking this item.

14.3 Procedure AP-ELEC.2 requires Operations to start both emergency diesel generators if any 480 volt safeguards bus voltage lowers to less than 420 volts. If bus voltage drops below 414 DA-EE-93-006-08 Page 48 of 49 Revision 5

volts, Operations is required to transfer the safeguards busses to the emergency diesel

'generators. It is recommended that these values are revised to start the diesel generator at a voltage of 440 volts and transfer safeguards busses to the diesel generators at a voltage of 430 volts. Based on a review of AutoLog values from January of 2005 until August of 2007, the minimum bus voltage recorded is 462 volts with average values of 480 volts. Therefore a value of 440 volts is indicative of a problem. This procedure change would provide -

additional assurance that electrical loads would not be operated for a significant amount of time at minimum acceptable voltage. CA-2007-001371 is currently tracking a revision to AP-ELEC.2 for this issue.

14.4 Calibration procedure PR-1.1 and test procedures PT-9.1.14, PT-9.1.16, PT-9.1.17 and PT-9.1.18 should be revised to incorporate the new setpoints contained in this calculation.

Required changes are identified in the "Conclusions" sections of this calculation (3.2, 3.3, 3.4 and 3.5).
