a. ECCS division I ennsisting of:

1.

The OPERABLE low pressure core spray (LPCS) system with a flow path capable of taking suction from the suppression pool and transferring the water through the spray sparger to the reactor vessel.

2.

The OPERABLE low pressure coolant injection (LPCI) subsystem A" of the RHR system with a flow path capable of taking suction from the suppression pool and transferring the water to the reactor vessel.

3. 7 OPERABLE ADS valves.
b. ECCS division II consisting of:

1.

The OPERABLE low pressure coolant injection (LPCI) subsystems "B" and "C" of the RHR system, each with a flow path capable of taking suction from the suppression pool and transferring the water to the reactor vessel.

2. 7 OPERA 8LE ADS valves.

c.

ECCS division III consisting of the OPERABLE high pressure core spray (HPCS) system with a flow path capable of taking suction from the suppression pool and transferring the water through the spray sparger to the reactor vessel.

APPLICABILITY: OPERATIONAL CONDITION 1, 2*'# and 3*'

aihe A05 is not required to be OPERABLE when reactor steam dome pressure is less than or equal to 100 psig.

EMERGENCY CORE COOLING SYSTEMS SURVEILLANCE REQUIREMENTS 4.5.1 ECCS division 1, II and III shall be demonstrated OPERABLE by:

a. At least once per 31 days for the LPCS, LPCI and HPCS systems:
1. Verifying by venting at the high point vents that the system piping from the pump discharge valve to the system isolation valvo is filled with water.
2. Verifying that each valve (manual, power operated or automatic),

in the flow path, that is not locked, sealed, or otherwise secured in position, is in its correct position.  ;

b. Verifying that, when tested pursuant to Specification 4.0.5, each: .
1. LPCS pump develops a flow of at least 5010 gpm a pump differential pressure greater than or equal to sid.
2. LPCI pump develops a flow of at least 5050 gpa a pump differential pressure greater than or equal to sid. ,
3. HPCS pump develops a flow of at least 5010 gpa a pump differential pressure greater than or equal to sid. ,

Actual injec-tion of coolant into the reactor vessel say be excluded from this test.

d. At least once per 18 months, for the HPCS system, verifying that the suction is automatically transferred from the condensate storage tank to the suppression pool on a condensate storage tank low water 1evel signal and on a suppression pool high water level signal, and verifying that the HPCS system will automatically re Reactor pts untg
