I PAGE 6 OF 30 E-NTERGY RIVER BEND STATION 1.0 PURPOSE AND DESCRIPTION

1.1 Purpose

The purpose of this calculation is to determine the uncertainty associated with the Division I &II, Safety-Related, 4.16 kV undervoltage time delay relays. Nominal trip Set points and Allowable values will be determined by the Electrical Engineering group in calculation G 13.18.3.1

  • 001 and documented on the applicable BE drawing.1.2 Loop Descriptions Each 4.16 kV emergency bus has its own independent Loss Of Power (LOP) instrumentation and associated trip logic. The voltage for the Division I and II buses is monitored at two levels, which can be considered as two different undervoltage functions; loss of voltage and sustained degraded voltage.Each 4.16 kV bus is monitored by three degraded voltage relays whose outputs are arranged in a two-out-of-three logic configuration (Reference 3.12). The channels include electronic equipment (e.g., trip units) that compares measured input signals with pre-established setpoints.

When the setpoint is exceeded, the channel output relay actuates a time delay relay, which then outputs a LOP trip signal to the trip logic. Two different time delays are applied depending on whether a LOCA signal is present at the time of the degraded voltage. The LOCA and Non-LOCA time delay is provided by the combination of the 27N relay and the 62K relays.1.3 Design Bases/Design Bases Event Per Bases B 3.3.8.1, Reference 3.7.3, "successful operation of the required safety functions of the Emergency Core Cooling Systems (ECCS) is dependent upon the availability of adequate power sources for energizing the various components such as pump motors, motor operated valves, and the associated control components.

The LOP instrumentation monitors the 4.16 kV emergency buses. Offsite power is the preferred source of power for the 4.16 kV emergency buses. If the monitors determine that insufficient power is available, the buses are disconnected from the offsite power sources and connected to the onsite diesel generator (DG) power sources.

1 PAGE 7 OF 30 ENTERGY RIVER BEND STATION 1.4 Degree of Accuracy/Limits of Applicability The results of this calculation are based on the statistical methods of at least 95% probability of occurrence for a two sided probability distribution in accordance with 7224.300-100-001 B,"General Electric Instrument Setpoint Methodology," (Reference 3.3) and EN-IC-S-007-R,"Instrument Loop Uncertainty

& Setpoint Calculations," (Reference 3.2). One-sided probability I could be used since the time delay relay performs its safety function in the decreasing direction only. However a two sided probability is used for added conservatism.

The results of this calculation are valid under the Assumptions stated in Section 7.0 of this calculation.

The appropriate use of this calculation to support design or station activities, other than those specified in Section 1.1 of this calculation, is the responsibility of the user.1.5 Applicability A data analysis has been performed in order to determine which, if any, redundant instrument loops are bounded by the results of this calculation.

This calculation is applicable to the Loops associated with the primary elements stated in Section 2.1. The results of this calculation are bounding for the applicable instrument loops, based on such factors as instrument manufacturer and model number, instrument location/environmental parameters, actual installation and use of the instrument in process measurements.

7.1 Assumptions

that do not require confirmation

7.1.1 Miscellaneous

Allowance (ML)A miscellaneous allowance has not been applied to the uncertainty of the devices ev with intermediate rounding of values in the conservative direction, sufficient conservatism has been introduced.

7.1.2 For conservatism, all uncertainties given in vendor data specifications are assumed to be 7.1.3 Zero Effect (ZE)Not applicable

7.1.4 Seismic

Effects (SE)Reference

3.9.2 states

that the undervoltage relays have been tested to 6 g ZPA "without damage, malfunction or failure." Reference

3.5 defines

the expected level of seismic activity for the 98 ft elevation of the control building as less than 3g. Therefore, seismic effects are assumed to be 0.7.1.5 Radiation Effects (RE) & Radiation Drift Effect (RD)Are not applicable to the relays and transformers evaluated by this calculation as they are located in a mild environment (Reference 3.6).7.1.6 Power Supply Effects (PS)Per Reference 3.9.1, the model 62K relay has a power supply effect of+/- 1% over the allowable DC control power range of 100 to 137.5 VDC (-20,+10%

variation).

Per Reference 3.9.2, the model 62L1 relay has a power supply effect of+/- 2% over the allowable DC control power range of 100 to 137.5 VDC (-20,+l0%

variation).

Per Reference 3.11.5, the allowable voltage range is 130 to 140 VDC (104 to 112%). Since the relay will only see an 8% voltage variation, +/-1% and +/-2% deviations will be used to calculate the PS effects for the respective time delay relays in this calculation.

Measurement Uncertainty (PM)Not applicable SETPOINT CALCULATION CALC. NO. G13.18.6.2-ENS*006 ENGINEERING DEPARTMENT REVISION:

1----19 OF 30 ENTERGY RIVER BEND STATION 7.1.8 Static Pressure Effects (SP)Not applicable

7.1.9 Humidity

Effects (HE)The relays were specified by the switchgear manufacturer and are assumed to be designed to withstand the environmental effects in the mounting location without effect.Per Reference 3.6, the humidity range for environmental zone CB-98 is 20 to 90% RH.Therefore, it is assumed that Humidity effects are negligible.

7.1.10 Insulation Resistance Effects (IR)(IR) effects, which may result in degradation of circuit insulation, are not applicable to the devices and circuits addressed by this calculation.

The timers evaluated are not low-current DC devices affected by current leakage due to insulation resistance degradation.

7.1.11 Voltage Drop Voltage drop due to long wiring lengths between source and load are not applicable because the timing relays evaluated are located in the same switchgear as their power source.7.1.12 Temperature Effects (TE)Per ABB Descriptive Bulletin IB 18.7.7-1G, Ref. 3.9.1, the temperature effect for an ITE 62K relay is 6% of setting over a span of 50 -131'F (-15'C -+55QC) or 0.0476% per 0 F.This value will be used to determine relay temperature effects.Per ABB Descriptive Bulletin IB 18.7.7-4B, Ref. 3.9.2, the temperature effect for an ITE 62L relay is 4% of setting over a span of-4 0 -131'F (-20'C -+55QC) or 0.0296% per °F.This value will be used to determine relay temperature effects.7.1.13 Temperature Drift Effects (TD)The drift analysis performed in Reference 3.14.3 is assumed to encompass all components of drift and drift effects, including drift due to temperature variations.

The drift analysis performed in Reference 3.14.3 is assumed to encompass all components of drift and drift effects except for temperature drift effects which are assumed to be included in the Reference Accuracy of the device.7.1.14 Instrument Drift None SETPOINT CALCULATION CALC.

Assuming linearity, this yields an effect of 0.0476 VAC/°F. The relays are housed inside the DIV I and II switchgear which are assumed to maintain an internal temperature of 104°F to prevent condensation.

Reference 3.6 also states that for 1% of the calendar year (30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />), the temperature could be 5°F higher. This is considered negligible.

However, the relay is calibrated in the electrical or relay shop which is assumed to be maintained at 73 0 F. Therefore:
