Emeraency Feedwater Tank Level (continued)
The dedicated emergency feedwater (EFW) tank provides the assured, safety grade water supply for the Emergency Feedwater System. The EFW tank inventory is monitored and displayed by 0 to 38 feet control room level indications. The control room indicators and alarms are considered the primary indication used by the operator. Therefore, -the LCO deals specifically with this portion of the instrument string.
The design basis accidents which require emergency feedwater are those in which the main feedwater supply and/or the electrical supply to the vital feedwater -
auxiliaries has been lost, e.g., a feedwater line break or a loss of offsite power.
In the event of such a loss er feedwater, the EFW tank is the initial i
source of water for the EFW System. As the EFW tank l
is depleted, manual operator action is necessary to l.
replenish the EFW tank or to realign the suction to the EFW pumps.
Since tank level is required by the operator for manual actions following an event, it has been included in this LCO.
183. Core Exit Temoerature 'Sackus) YT6EiiidEossTeT The core exit thermocouples (CETs) provide an indication of the reactor coolant temperature as it exits the active region of the core. The CET5dpfovid5
,inputsto accident monitoring instrumentation provides a display of core exit temperature over a range of 0 l
to 2500 F.
The displays consists efkissd[in~cluds 16 separate temperature measurements from 16 CETs, four from each quadrant.

Emeraency Feedwater Flow EFW Flow instrumentation is provided to monitor operation of decay heat removal via the OTSGs. The EFW injection flow to each OTSG (2 channels per OTSG, one associated with each EFW injection line) is determined from a differential pressure measurement calibrated to a span of 0 gpm to 1000 gpm.
Each differential pressure transmitter provides an input to a control room indicator and the plant computer.
EFW Flow is used by the operator to determine the need to throttle flow during accident or transient conditions to prevent excessive RCS cooldown rates when low decay heat levels are present.
EFW Flow is also used by the operator to verify that the EFW System is delivering the correct flow to each OTSG.
However, the primary indication of this function is provided by OTSG level.
These instruments are not assumed to provide information required by the operator to take a mitigation action specified in the safety analysis.
As such, they are not Type A variables.
However, the monitors are deemed risk significant (Category 1) and are included within the LCO based upon this consideration.

Low Pressure Iniection Flow (continued)
Low pressure injection flow instrumentation is provided to monitor flow to the RCS following a large break LOCA.
It is also used to monitor LPI flow during piggy back operation following a small break LOCA. The low pressure injection flow to the rector (2 channels, one associated with.each LPI injection line) is determined from a differential pressure measurement calibrated to a span of 0 gpm to 5000 gpm.
~
The LPI flow indication is used by the operator to throttle the flow to < 2000 gpm prior to switching the pump suction from the BWST to the RB sump. This assures adequate net positive suction head (NPSH) is maintained to the pump. The indication is also used to verify LPI flow to the reactor as a prerequisite to termination of HPI flow.
Since low pressure injection flow is a Type A variable on which the operator bases manual actions required for event mitigation for which no automatic controls are provided, it has been included in this LCO.

Degrees of Subcooling Two channels of subcooling margin with inputs from RCS hot leg temperature (T"), core exit temperature, and RCS pressure are provided byltheiSafetyl.Parameteh DisplaV! System:(SPDS)'. Multiple core exit temperatures are auctioneered with only the highest temperature being input to the monitor. A-note-has been added to indicate that the twc channels-of subcooling margin are backed up by either of two ind+eations of subeooWg-margin based-on-simi+ar inputs through the-Safety-Parameter Display System (SPOS).

This is cons 4dered-necessary-because-the core ex+t thermecouple-4nputs to the subccoling margin monitors are not environmentally-qualified.
The T inputs to the SPDS subcooling margin monitors and-SbDS operate over a range of 120 to 920 F.
The core exit temperature inputs operate over a range of 150-to 2000ar and 150 0 to 2500 F for-the-subcooHng-margi-n monitors and SPDS, respectively.
RCS pressure inputs operate over a wide range of 200 to 2500 psig anddow i angelofl0;tC600cpsig.

Dearees of Subcooling (continued)
The subcooling margin monitors are used to verify the existence of, or to take actions to ensure the restoration of subcooling margin.
Specifically, a loss of adequate subcooling margin during a LOCA requires the operator to trip the reactor coolant pumps (RCP's), to ensure high or low pressure injection, and raise the steam generator levels to the inadequate subcooling margin level.
Since degrees of subcooling is a. Type A variable on which the operator bases manual actions required for event mitigation for l
which no automatic control are provided, it has been l
included in this LCO.

in the control room to monitor the operational status of the EDG.
EDG Power (kW) output indication is a type A variable because EDG kW indication provides the control room operator EDG load management capabilities.
EDG load management enables the operator to base manual actions i
of load start and stop for event mitigation.
