' '". EMERGENCY CORE COOLING SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) 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.
At least once per 92 days, by verifying that the system develops a flow of at least 4250 gpm for a system head corresponding to a reactor pressure = 1000 psig when steam is being supplied to the turbine at 1000. +20. -80, psig.
c.
At least once per 18 months by:
1.
Performing a system functional test which includes simulated automatic actuation of the system throughout its emergency o>erating sequence and verifying that each automatic valve in tie flow path actuates to its correct position. Actual injection of coolant into the reactor vessel is excluded from this test.
~
2.
Verifying that the system develops a flow of at least 4250 gpm for a system head corresponding to c reactor pressure of = 165 psig when steam is being supplied to the turbine at 165.
15.
psig.
3.
Verifying that the suction for the HPCI system is automatically transferred from the condensate storage tank to the suppression pool on a condensate storage tank low water level signal or suppression pool high water level signal.
4.
Verifying that the ECCS RESPONSE TIME for the HPCI system is within its limit.'
' Instrumentation response time may be assumed to be the design instrumentation response time.
