3/4.5.4 SEAL INJEC'TION FLQW Th* Reactor Coolant Pump (RCP) seal injection flow restriction limits th* amount of !CCS flow that would bt diverted from the injection path following an ECCS actuation.
Thia limit i* baaed on safety analysis assumptions, sine* RCP seal injection flow is not isolated during Safety Injection (SI).
Th* LCO is not atrictly a flow limit, but rather a flow limit based on £ flow line reaiata.nce.
Lin* pressure and flow muat bt known to establish the proper line reaiata.nct.
Plow line resistanct ia determined by assuming that the RCS prtaaure i* at normal operating pre**ur*, &nd that th* centrifugal charging pWllp diac:harge preasure is greater th.an or equal to 2430 p8ig.
Charging pump header pr***ur* i* used instead of RCS pressure, since it is more reprtaentativ* of flow diversion during &n accident.
Th* additional LCO modifier, charging flow control v&lvfll full open, i.s required since the valve is de*igned to fail open. *with the LCO specified di.scharge pre**ur* and control valve position, a flow limit is e*t&blished.

ECCS SUBSYSIEMS !Continued)
With the RCS temperature below 350°F, one OPERABLE ECCS subsystem is acceptable without single failure consideration on the basis of the stable reactivity condition of the reactor and the limited core cooling requirements.
The limitation for a maximum of one *afety injection pump or one centrifugal charging pump to be OPERABLE and th* surveillance Requirement to verify all safety injection pumps except the allowed OPERABLE safety injection pump to be inoperable below 312°F provides assurance that a mass addition pressure transient can be relieved by the operation of a single POPS relief valve.
The surveillance requirements, which are provided to ensure the OPERABILITY of each component, ensure that, at a minimum, the assumptions used in th* saf aty analyses are met and that aubsy*tem OPERABILITY is maintained.
The safety analyses make the assumption* with respect to:
- 1) both th* maximum and minimum total sy*tem resi*tance, and 2) both the maximum and minimum branch injection line resistance.
These resistances, in conjunction with th* range* of potential pump performance, are used to calculate th* maximum and minimum ECCS flow as*umed in th* safety analyses.
The maximum and minimum flow surveillance requirement* in conjunction with the maximum and minimum pump performance curve* ensures that the assumption* of total system resistance and the di*tribution of that system resistance among the variou* paths are met.
The maximum total pump flow aurveillanc* requirements ensure the pump runout limits of 560 gpm for the centrifugal charging pumps and 675 gpm for the safety injection pump* are not exceeded *...__
The surveillance requirement for th* maximum difference between the maximum and minimum individual injection line flow* ensure that the minimum individual injection line resistance assumed for th* spilling line following a LOCA is m~t.
