The LOP instrumentation ~is required for the Engineered SAFETY ANALYSES, Safety Features to function in any accident with a loss of offsite power. The required channels of LOP instrumentation j LCO, and
- APPLICABILITY ensure that the ECCS and other assumed systems powered from
' the DGs provide plant protection in the event of any of the
- analyzed accidents in References 2, 3, and 4'in which a loss l of offsite power is assumed. The initiation of the DGs on l loss of offsite power, and subsequent initiation of.the~
ECCS, ensure that the fuel peak cladding temperature remains l
below the limits of 10 CFR 50.46.
Accident analyses credit the loading of the DG based on the loss of offsite power during a loss of coolant accident l
(LOCA).
The diesel starting and loading times have been included in the delay time associated with each safety l
5 system component requiring DG supplied power following a
- loss of offsite power.
d The LOP instrumentation satisfies Criterion 3 of the NRC 4
Policy Statement.
The OPERABILITY of the LOP instrumentation is depende it upon i
the OPERABILITY of the individual instrumentation channel i
Functions specified in Table 3.3.8.1-1. Each Function must have a required number of OPERABLE channels per 4.15 kV j
emergency bus; with their setpoints within the specified 2
Allowable Values. A channel is inoperable if its actual trip setpoint is not within its, required Allowable 'Value.
l The actual setpoint is calibrated consistent with applicable setpoint methodology assumptions.
The Allowable Values are specified for each Function in the Table. Nominal trip 'setpoints are specified in the setpoint calculations. The nominal setpoints are selected to ' ensure that the setpoint does not exceed the Allowable Value between CHANNEL CALIBRATIONS.

i Prior to Release for Operations (RFO) of the associated plant modification (i.e., i modification AP-027 for Division 1 or AP-028 for Division 2 ), each Division 1 and Division 2 emergency bus Degraded Voltage Function is monitored by two undervoltage i relays for each emergency bus whose outputs are arranged in a two-out-of-two logic configuration. The output of this logic inputs to a time delay relay (Ref.1). Prior to RFO of modification AP-029, the Division 3 emergency bus Degraded Voltage Function is monitored by one undervoltage relay with three output contacts arranged in a three-out-of-three logic configuration. The output of this logic inputs to a time delay relay.
Following RFO of the associated plant modification, each Division 1, Division 2, and Division 3 emergency bus Degraded Voltage Function is monitored by two undervoltage relays for each emergency bus whose outputs are arranged in a two-out-of-two logic configuration.

The time delay specified for the Divisions 1 and 2 4.16 kV Emergency Bus Loss of Voltage Functions corresponds to a voltage at the 120-volt Basis trip setpoint of a 67 volts and s 97 volts. Lower voltage conditions will result in decreased trip times. The l Division 3 4.16 kV Emergency Bus Loss of Voltage Function 120-volt Basis trip setpoint is a 67 volts and s 78 volts.
Six channels of 4.16 kV Emergency Bus Undervoltage (Loss of Voltage) Function per associated emergency bus for Divisions 1 and 2 and four channels for Division 3 are only required to be OPERABLE when the associated DG is required to be OPERABLE to ensure that no single instrument failure can l
preclude the DG function. (Six channels input to each of l the Division 1 and Division 2 DGs and four channels input to I
l the Division 3 DG. Each of the six channels for Division 1 and six channels for Division 2 is an inverse time delay rel ay. Each of these time delays are considered to be l separate channels. For Division 3, .the Loss of Voltage Function logic inputs to a single time delay relay. Thus, l only one time delay channel is associated with Division 3.)
Refer to LCO 3.8.l', "AC Sources-Operating," and LC0 3.8.2, "AC Sources-Shutdown," for Applicability Bases for the DGs.

A reduced voltage condition on a 4.16 kV emergency bus indicates that while offsite power may not be completely lost to the respective emergency bus, power may be insufficient for starting large motors without risking l
damage to the motors that could disable the ECCS function.
! Therefore, power supply to the bus is transferred from offsite power to onsite DG power when the voltage on the bus drops below the Degraded Voltage Function Allowable Values (degraded voltage with a time delay). This ensures that adequate power will be available to the required equipment.

As stated above, the purpose of this instrumentation is to ensure that sufficient power will be available to support the ECCS function during a LOCA. During a LOCA, the ECCS and other safety systems will be initiated at the start of the event. This large loading of .
l the safety buses results in a voltage transient of sufficient magnitude to start the degraded voltage timers. If the degraded voltage relays do not reset, which requires the voltage to i be restored to a level above the relay reset setpoint, the bus undervoltage time delay relays will trip, resulting in bus transfer to the DGs. Thus, the relay reset (pick-up) setpoint must be high enough to ensure adequate voltage for the safety-related loads. ,
Prior to RFO of the corresponding plant modification (i.e., modification AP-027 for '
Division 1, AP-028 for Division 2, or AP-29 for Division 3), the Degraded Voltage Function Allowable Value specified is the relay dropout setpoint. The Allowable Value has a 120-volt basis of 2107.5 volts and s109.5 volts (Ref. 5). Following RFO of the corresponding plant modification, the Degraded Voltage Function Allowable Value specified is the relay reset setpoint. The Allowable Value has a 120-volt basis of 2111.08 ,
volts and si11.82 as specified in IP Calculation 19-AN-19 (Ref. 5).
